About this study

Official title: Reduced Estimated Glomerular Filtration Rate (eGFR)and Prediction of Cardiovascular Disease and Renal Outcome in Subjects With Type 2 Diabetes: Italian Multicenter Study

Reduced glomerular filtration rate (GFR) has been recently shown to be a powerful predictor of cardiovascular morbidity and mortality in the general population, independent of traditional cardiovascular risk factors.

This observational study is aimed at assessing the association of reduced estimated GFR with cardiovascular morbidity and mortality in a large italian population (at least 15,000 subjects) of type 2 diabetic outpatients over a 4-year follow-up.

Read the detailed description

Reduced GFR has been recently shown to be a powerful predictor of cardiovascular morbidity and mortality in the general population, independent of traditional cardiovascular risk factors. Since type 2 diabetic patients show increased cardiovascular morbidity and mortality as compared with the general population, the identification of predictors of cardiovascular disease in these patients is of fundamental importance for clinical purposes. One of these predictors is increased urinary albumin excretion rate, which is associated with an increased risk of cardiovascular disease more than of end-stage renal disease. However, a growing body of evidence indicates that a significant proportion of normoalbuminuric diabetic patients, particularly with type 2 diabetes, may exhibit reduced GFR. It is currently unknown the predictive role of this abnormality toward cardiovascular events and death, independent of albuminuria and other known risk factors, in the diabetic population.

This observational study is aimed at assessing the association of reduced estimated GFR with cardiovascular morbidity and mortality in a large italian population (at least 15,000 subjects) of type 2 diabetic nondialytic outpatients over a 4-year follow-up.

Secondary endpoints are to assess in this population:

  • the prevalence and incidence of reduced GFR, as classified according to the National Kidney Foundation criteria, and its association with traditional cardiovascular risk factors;
  • the prevalence, incidence and cardiovascular predictivity of micro and macroalbuminuria.

Patients will be recruited from electronic records of 20 italian outpatients diabetic clinics.

Routine anamnestic, clinical, laboratory and instrumental data will be recorded at baseline and over 4 years to obtain information about:

  • renal function (albumin/creatinine ratio, serum creatinine with estimation of glomerular filtration rate [eGFR]);
  • cardiovascular risk factors (smoking, physical activity, family history of diabetes, dyslipidemia, hypertension and cardiovascular disease, BMI and waist circumference, total, LDL, HDL and non-HDL cholesterol, triglycerides, arterial blood pressure and HbA1c);
  • current glucose-, lipid- and blood pressure-lowering and anti-platelet or anti-coagulant treatment;
  • other illnesses;
  • cardiovascular events (myocardial infarction, stroke, lower limb ulcer/gangrene/amputation and coronary, carotid and lower limb revascularization, endovascular/surgical) and deaths.

These data will be derived from the electronic database of each participating center.

Laboratory analyses will be performed in each centre laboratory after proper standardization of analytical techniques.

Where is the study taking place?

The record lists 20 sites in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

cardiovascular morbidity and mortality (time frame: 4 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00715481, which also lists 23 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Feb 2015.
