Nephropathy In Type 2 Diabetes and Cardio-renal Events

Nephropathy in Type 2 Diabetes: Effects of an Intensive Multifactorial Intervention Trial on Cardio-renal Events.

The NID-2 study, a multicentric study (21 centres enrolled), was planned in two phases:

Phase 1(observational study, completed in September 2005): after the identification of a type-2 diabetic population with typical Diabetic Nephropathy (DN), to study of the rate of renal and cardiovascular events during a middle term follow-up.

Phase 2(interventional study, started in October 2005): after randomization in two groups, a group (intervention group) is treated with an intensive multifactorial intervention whose aim is to reduce morbidity and mortality due to diabetic complications. The other group (control group) continues the conventional therapy . To avoid bias in the treatment in each center, the randomization was performed for centre.

The same patients that completed the first phase of the NID-2 study (observation) were enrolled for the phase 2 of the study (intervention).
