The drugs used to reduce glucose levels in patients with

type 2 diabetes seem important for the ultimate

cardiovascular outcome the combination of intensive

glycemic control when safely attainable with newer

diabetes drugs (empagliflozin canagliflozin liraglutide

and semaglutide) may decrease the incidence of MACE

nephropathy and retinopathy Moreover depending on the

drug used CV mortality and heart failure may also be

reduced

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

The drugs used to reduce glucose levels in patients with

type 2 diabetes seem important for the ultimate

cardiovascular outcome the combination of intensive

glycemic control when safely attainable with newer

diabetes drugs (empagliflozin canagliflozin liraglutide

and semaglutide) may decrease the incidence of MACE

nephropathy and retinopathy Moreover depending on the

drug used CV mortality and heart failure may also be

reduced

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

The drugs used to reduce glucose levels in patients with

type 2 diabetes seem important for the ultimate

cardiovascular outcome the combination of intensive

glycemic control when safely attainable with newer

diabetes drugs (empagliflozin canagliflozin liraglutide

and semaglutide) may decrease the incidence of MACE

nephropathy and retinopathy Moreover depending on the

drug used CV mortality and heart failure may also be

reduced

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

The drugs used to reduce glucose levels in patients with

type 2 diabetes seem important for the ultimate

cardiovascular outcome the combination of intensive

glycemic control when safely attainable with newer

diabetes drugs (empagliflozin canagliflozin liraglutide

and semaglutide) may decrease the incidence of MACE

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

The drugs used to reduce glucose levels in patients with

type 2 diabetes seem important for the ultimate

cardiovascular outcome the combination of intensive

glycemic control when safely attainable with newer

diabetes drugs (empagliflozin canagliflozin liraglutide

and semaglutide) may decrease the incidence of MACE

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

The drugs used to reduce glucose levels in patients with

type 2 diabetes seem important for the ultimate

cardiovascular outcome the combination of intensive

glycemic control when safely attainable with newer

diabetes drugs (empagliflozin canagliflozin liraglutide

and semaglutide) may decrease the incidence of MACE

nephropathy and retinopathy Moreover depending on the

drug used CV mortality and heart failure may also be

reduced

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

The drugs used to reduce glucose levels in patients with

type 2 diabetes seem important for the ultimate

cardiovascular outcome the combination of intensive

glycemic control when safely attainable with newer

diabetes drugs (empagliflozin canagliflozin liraglutide

and semaglutide) may decrease the incidence of MACE

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

SIRTUIN 6 EXPRESSION AND INFLAMMATORY ACTIVITY IN DIABETIC

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

The drugs used to reduce glucose levels in patients with

type 2 diabetes seem important for the ultimate

cardiovascular outcome the combination of intensive

glycemic control when safely attainable with newer

diabetes drugs (empagliflozin canagliflozin liraglutide

and semaglutide) may decrease the incidence of MACE

nephropathy and retinopathy Moreover depending on the

drug used CV mortality and heart failure may also be

reduced

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

The drugs used to reduce glucose levels in patients with

type 2 diabetes seem important for the ultimate

cardiovascular outcome the combination of intensive

glycemic control when safely attainable with newer

diabetes drugs (empagliflozin canagliflozin liraglutide

and semaglutide) may decrease the incidence of MACE

nephropathy and retinopathy Moreover depending on the

drug used CV mortality and heart failure may also be

reduced

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

The drugs used to reduce glucose levels in patients with

type 2 diabetes seem important for the ultimate

cardiovascular outcome the combination of intensive

glycemic control when safely attainable with newer

diabetes drugs (empagliflozin canagliflozin liraglutide

and semaglutide) may decrease the incidence of MACE

nephropathy and retinopathy Moreover depending on the

drug used CV mortality and heart failure may also be

reduced

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

The drugs used to reduce glucose levels in patients with

type 2 diabetes seem important for the ultimate

cardiovascular outcome the combination of intensive

glycemic control when safely attainable with newer

diabetes drugs (empagliflozin canagliflozin liraglutide

and semaglutide) may decrease the incidence of MACE

Zinman B Bergenstal RM Buse JB LEADER Steering Committee LEADER Trial Investigators Collaborators (2255)

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

Zinman B Bergenstal RM Buse JB LEADER Steering Committee LEADER Trial Investigators Collaborators (2255)

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

Zinman B Bergenstal RM Buse JB LEADER Steering Committee LEADER Trial Investigators Collaborators (2255)

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

SIRTUIN 6 EXPRESSION AND INFLAMMATORY ACTIVITY IN DIABETIC

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

Zinman B Bergenstal RM Buse JB LEADER Steering Committee LEADER Trial Investigators Collaborators (2255)

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

SIRTUIN 6 EXPRESSION AND INFLAMMATORY ACTIVITY IN DIABETIC

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

Zinman B Bergenstal RM Buse JB LEADER Steering Committee LEADER Trial Investigators Collaborators (2255)

BACKGROUND

The cardiovascular effect of liraglutide a glucagon-like peptide 1 analogue when added to standard care in patients with type 2 diabetes

remains unknown

METHODS

In this double-blind trial we randomly assigned patients with type 2 diabetes and high cardiovascular risk to receive liraglutide or placebo

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes nonfatal myocardial

infarction or nonfatal stroke The primary hypothesis was that liraglutide would be noninferior to placebo with regard to the primary outcome

with a margin of 130 for the upper boundary of the 95 confidence interval of the hazard ratio No adjustments for multiplicity were

performed for the prespecified exploratory outcomes

RESULTS

A total of 9340 patients underwent randomization The median follow-up was 38 years The primary outcome occurred in significantly fewer

patients in the liraglutide group (608 of 4668 patients [130]) than in the placebo group (694 of 4672 [149]) (hazard ratio 087 95

confidence interval [CI] 078 to 097 Plt0001 for noninferiority P=001 for superiority) Fewer patients died from cardiovascular causes in the

liraglutide group (219 patients [47]) than in the placebo group (278 [60]) (hazard ratio 078 95 CI 066 to 093 P=0007) The rate of

death from any cause was lower in the liraglutide group (381 patients [82]) than in the placebo group (447 [96]) (hazard ratio 085 95

CI 074 to 097 P=002) The rates of nonfatal myocardial infarction nonfatal stroke and hospitalization for heart failure were nonsignificantly

lower in the liraglutide group than in the placebo group The most common adverse events leading to the discontinuation of liraglutide were

gastrointestinal events The incidence of pancreatitis was nonsignificantly lower in the liraglutide group than in the placebo group

CONCLUSIONS

In the time-to-event analysis the rate of the first occurrence of death from cardiovascular causes nonfatal myocardial infarction or

nonfatal stroke among patients with type 2 diabetes mellitus was lower with liraglutide than with placebo

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Twenty-two diabetic patients were treated with drugs that work on the

Compared with nondiabetic plaques diabetic plaques had more inflammation

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

SIRTUIN 6 EXPRESSION AND INFLAMMATORY ACTIVITY IN DIABETIC

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

SIRTUIN 6 EXPRESSION AND INFLAMMATORY ACTIVITY IN DIABETIC

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Twenty-two diabetic patients were treated with drugs that work on the

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

Clinical studies suggest a link between peripheral insulin resistance and

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

A FIXED RATIO COMBINATION OF INSULIN DEGLUDEC AND LIRAGLUTIDE (IDEGLIRA) REDUCES GLYCEMIC FLUCTUATION AND

BRINGS MORE PATIENTS WITH TYPE 2 DIABETES WITHIN BLOOD GLUCOSE TARGET RANGES

KING AB1 PHILIS-TSIMIKAS A2 KILPATRICK ES3 LANGBAKKE IH4 BEGTRUP K4 VILSBOslashLL T5

BACKGROUND

Reducing glycemic fluctuation is important for optimal diabetes management This post hoc analysis examined glycemic

fluctuations and the proportion of subjects achieving recommended blood glucose targets with the fixed ratio combination of

insulin degludec and liraglutide (IDegLira) compared to insulin degludec (IDeg) and liraglutide alone

METHODS

We analyzed nine-point self-monitored blood glucose (SMBG) profiles from two randomized trials involving IDegLira in patients

with type 2 diabetes (T2D) and continuous glucose monitoring (CGM) data from a subset of patients in one of these trials to assess

glycemic fluctuation and day-to-day variability

RESULTS

Compared with IDeg IDegLira resulted in a greater proportion of subjects with SMBG values within target ranges (39-

90thinspmmolL) than IDeg for all pre- and postprandial values and for the full nine-point profile (Pthinspltthinsp005 for all) IDegLira also

resulted in a greater reduction in the range of SMBG values over 24thinsph than IDeg (Pthinsplethinsp00001) CGM data showed that IDegLira

provided greater reductions in interstitial glucose (IG) fluctuation (Pthinsp=thinsp00018) and postprandial IG increment (Pthinsp=thinsp00288)

compared with IDeg Compared with liraglutide IDegLira brought a higher proportion of subjects within SMBG target ranges (all

pre- and all postprandial values and the full nine-point profile Pthinspltthinsp001 for all) and resulted in a greater reduction of time outside

the IG target range (Pthinsp=thinsp00072) IDegLira also reduced mean IG more than liraglutide (Pthinspltthinsp00001)

CONCLUSIONS

Treatment with IDegLira allows more patients with T2D to maintain blood glucose within target ranges throughout the day than

either IDeg or liraglutide alone

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

Abstract

The role of sirtuin 6 (SIRT6) in atherosclerotic progression of diabetic

patients is unknown We evaluated SIRT6 expression and the effect

of incretin-based therapies in carotid plaques of asymptomatic diabetic

and nondiabetic patients Plaques were obtained from 52 type 2

diabetic and 30 nondiabetic patients undergoing carotid endarterectomy

Twenty-two diabetic patients were treated with drugs that work on the

incretin system GLP-1 receptor agonists and dipeptidyl peptidase-4

inhibitors for 26 plusmn 8 months before undergoing the endarterectomy

Compared with nondiabetic plaques diabetic plaques had more inflammation

and oxidative stress along with a lesser SIRT6 expression and collagen

content Compared with non-GLP-1 therapy-treated plaques GLP-1 therapy

-treated plaques presented greater SIRT6 expression and collagen content and less inflammation and oxidative stress

indicating a more stable plaque phenotype These results were supported by in vitro observations on endothelial

progenitor cells (EPCs) and endothelial cells (ECs) Indeed both EPCs and ECs treated with high glucose (25 mmolL) in

the presence of GLP-1 (100 nmolL liraglutide) presented a greater SIRT6 and lower nuclear factor-κB expression

compared with cells treated only with high glucose These findings establish the involvement of SIRT6 in the inflammatory

pathways of diabetic atherosclerotic lesions and suggest its possible positive modulation by incretin the effect of which is

associated with morphological and compositional characteristics of a potential stable plaque phenotype

MODULATION OF GLP-1 SIGNALING AS A NOVEL THERAPEUTIC APPROACH

IN THE TREATMENT OF ALZHEIMERS DISEASE PATHOLOGY Tramutola A Arena A Cini C Butterfield DA Barone E

Clinical studies suggest a link between peripheral insulin resistance and

cognitive dysfunction Post-mortem analyses of Alzheimer disease (AD)

subjects revealed insulin resistance in the brain suggesting a role of this

condition in cognitive deficits observed in AD In this review we focus on the

glucagon-like peptide-1 (GLP-1) signaling pathway whose role in the brain

is collecting increasing attention because of its association with insulin

signaling activation Areas covered The role of GLP-1-mediated effects in the

brain and how they are affected along the progression of AD pathology is

discussed Furthermore we provide a comprehensive discussion about the use

of GLP-1 mimetics drugs which have been developed as a treatment for T2DM

but seem to possess a number of other physiological properties including

neuroprotective and anti-inflammatory effects that may be useful to slow AD

progression Expert commentary The repurposing of antidiabetic drugs for

the modulation of brain insulin resistance in AD appears to be of great interest

The beneficial effects on synaptogenesis neurogenesis and cell repair as well

as the reduction of the chronic inflammatory response and most importantly

the reduction of amyloid plaques in the brain indicate that these drugs have

promise as novel treatments for AD
