RIACE is a multicentre observational prospective study that is being conducted in 19 collaborating centres in Italy

Recruitment of patients with T2DM (n. 15,993) started in 2007 and was completed in 2008

160 subjects were excluded due to missing or implausible values; data from the remaining 15,773 patients were than analyzed

Age: 66.0±10.3 years (median 67 years)

Diabetes duration: 13.2±10.2 years (median 11 years)

56.8% male and 43.2% female

13.593 subjects (86%) completed the 4 to 6 year follow-up NCT00715481; URL http://clinicaltrials.gov/show/NCT00715481

Conclusions (1)

Non-albuminuric renal impairment is the predominant clinical phenotype in patients, particularly women, with reduced eGFR.

Concordance between CKD and diabetic retinopathy is low, with only a minority of patients with renal dysfunction presenting with any or advanced retinal lesions.

The non-albuminuric form is associated with a significant prevalence of CVD, especially at the level of the coronary vascular bed.

Even within the normoalbuminuric range, in type 2 diabetic patients, AER is correlated with several risk factors which are potentially susceptible of therapeutic intervention.

Page 51: La Nefropatia Diabetica: nuove acquisizioni ...iscrizioni.fclassevents.com/nefrologia2014/presentazioni/4/08_Penno.pdf · La Nefropatia Diabetica: nuove acquisizioni epidemiologiche

Conclusions (2)

CKD is associated with HbA1c variability more than with average HbA1c, whereas retinopathy and CVD are not.

CKD is associated with hypertriglyceridemia and with resistant hypertension (likely bidirectional?).

Non-albuminuric renal function impairment is also detectable in a high proportion of patients with type 1 diabetes.
