Pathogenesis of T2DM in aging

Diabetes Risk Factors in

Aging

Zamboni M et al. Nutr Metab Cardiovasc Dis, 2008

A new link between aging and diabetes:

the sarcopenic obesity

The general population is ageing

DM has a high prevalence, which increases substantially with

age

The socio-economic burden of DM will only continue to grow

DM is considered to lead to accelerated aging

The diabetic population has a high prevalence of geriatric

syndrome

DM emerged as a significant predictor of progression in any

frailty characteristics

Rationale for treating elderly diabetic

people

To keep patients aymptomatic

To prevent either acute or chronic

complications

To preserve QoL

To avoid adverse drug reactions

Il caso di Aristide…..

77 anni con 4 anni di storia di T2DM. Anamnesi positiva per ischemia cardiaca e

osteoartrite degenerativa della colonna

Terapia

• Metformina 1 g bid, aspirina 75 mg qd, bisoprolol 5 mg qd, ISMO 10 mg bid, ramipril 5

mg bid, simvastatina 40 mg qd

All’obiettività:

• Peso 95 kg; BMI 33 kg/m2; PA140/75 mmHg; polso 65 bpm

Laboratorio:

• HbA1c: 8.6% (70 mmol/mol)

• eGFR: 42 mL/min/1.73 m2

• Total cholesterol: 151 mg/dl (3.9 mmol/L)

• Low-density lipoprotein cholesterol: 77 mg/dl (2.0 mmol/L)

• High-density lipoprotein cholesterol:42 mg/dl (1.1 mmol/L)

• Plasma triglyceride: 185 mg/dl (2.1 mmol/L)

BMI=body mass index; HbA1c=haemoglobin A1c.

Secondo voi, qual’è la principale considerazione da

fare rispetto alla terapia del Sig. Aristide?

1. Evitare l’ipoglicemia

1. Evitare l’aumento del peso

2. Ridurre i potenziali rischi di interazione tra farmaci

3. Valutare la sicurezza di ogni ulteriore trattamento

farmacologico

Quale sarebbe la vostra opzione

terapeutica per il Sig. Aristide?

1. Sulfonilurea

2. Glinide

3. Pioglitazone

4. Insulina

5. Agonista del recettore GLP-1

6. Inibitore DPP-4

DPP-4=dipeptidyl peptidase-4; GLP-1=glucagon-like peptide-1.

Alcuni problemi nella cura di Aristide

• Ipoglicemia

• Peso corporeo

• Sottostante malattia cardiovascolare

• Farmacoterapia multipla e complessa – interazione tra

farmaci

• Insufficienza renale

With increasing age, potential reaction time between awareness and onset of

symptoms is decreased, contributing to an increased risk for asymptomatic

hypoglycaemia and greater susceptibility to cognitive impairmenta,1,2

Thresholds for hypoglycaemia symptoms

vary with agea,1,2

Snyder RW, Berns JS. Semin Dial. 2004;17:365-70.

Recommendations for altering therapy in case of

reduced glomerular filtration rate (GFR):

Insulin (rough rule of thumb) › GFR 10–50 ml/min, reduce insulin dosage by 25%

› GFR <10 ml/min, reduce insulin dosage by 50%

Avoid metformin and miglitol

Reduce dose and use with caution: glibenclamide;

Impaired renal function and risk of drug-

induced hypoglycaemia

Although the risk of lactic acidosis on metformin is 10–20 times lower than

that on phenformin and does not differ from the risk in patients not taking

the drug, this agent still carries the historic burden of its predecessors. It is

even doubtful whether metformin plays a causal role in the pathogenesis of

lactic acidosis at all……….. We believe that standard contraindications to

the use of metformin should be relaxed, and that the benefits of reducing

the number of patients excluded from using it would by far outweigh the

potential risks. We propose removal of the following contraindications from

the list:

1. old age;

2. chronic renal insufficiency (as long as GFR >40 ml/min);

3. chronic heart failure (NYHA stages I and II); and

4. discontinuation of metformin therapy 2 days before surgery and i.v.

contrast medium administration.

Tolerability and efficacy of vildagliptin in T2DM

patients with moderate or severe renal insufficiency

• Primary objective: to evaluate the safety and tolerability of vildagliptin (50 mg once

daily) vs placebo as monotherapy or add-on therapy to other antidiabetic drugs in

patients with T2DM and moderate or severe renal impairment during

24 weeks of treatment

• Key exploratory objective: to evaluate the efficacy of vildagliptin vs placebo in HbA1c

and FPG reduction from baseline after 24 weeks of treatment

aRandomised: patients must remain on their current antidiabetic therapy (stable dose for at least 4 weeks prior to visit 1) or remain untreated for

the duration of the study if patient is not on antidiabetic therapy at study entry (unless patient meets criteria for rescue medication).

Interaction of DPP4 inhibitors with cytochrome p450

The choice of anti-hyperglycaemic agent should focus on:

Drug safety

Heart failure

Renal dysfunction

Bone fractures

Drug-drug interactions

Performance status

Strategies specifically minimising the risk of low

blood glucose may be preferred

In the elderly, the basic principle should be

“START LOW, GO SLOW”
