Nephropathy In Type 2 Diabetes and Cardio-renal Events (NID-2)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified December 2011 by Sasso Ferdinando Carlo, Second University of Naples.

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

Phase 1(observational study, completed at 2007): after the identification of a type-2 diabetic population with typical DN, to study of the rate of renal and cardiovascular events during a middle term follow-up.

Phase 2(interventional study, started at 2007): 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.

Primary Outcome Measures:
  • CV events (total CV mortality, non fatal IMA, non fatal stroke, TIA, major amputations, by-pass or PTCA) [ Time Frame: 4 years ]

Secondary Outcome Measures:
  • A) (In patients with microalbuminuria) • Progression to macroalbuminuria • Regression to normoalbuminuria B) (In patients with macroalbuminuria) • Doubling time of serum creatinine • Reduction of proteinuria to <0,5 g/die [ Time Frame: 4 years ]

Enrollment: 850
Study Start Date: March 2003
Estimated Study Completion Date: September 2012
Estimated Primary Completion Date: July 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
Control group patients will continue their usual therapy. During the study such patients could receive all the therapeutic modifications according to the good medical practice of the specialist.
Drug: current therapy
the patients have to be treated according the standard good medical practice by any center
Experimental: 2

An intensive multifactorial intervention is performed to achieve the goals for the following risk factors: hypertension, hyperglycaemia, lipids, anaemia.

In particular, new antihypertensive drugs will be added one by one until the achievement of blood pressure target (<130/80 mmHg).

Drug: irbesartan

Therapy for hypertension:

- Step 1: irbesartan 300 mg/die and ramipril 10 mg/die

Drug: ramipril

Therapy for hypertension:

- Step 1: irbesartan 300 mg/die and ramipril 10 mg/die

Drug: hydrochlorothiazide

Therapy for hypertension

- Step 2: Diuretic (hydrochlorothiazide 12.5-25 mg/die if serum creatinine <2 mg/dl, furosemide 25-75 mg/die if serum creatinin ≥2 mg/dl)

Drug: furosemide

Therapy for hypertension

- Step 2: Diuretic (hydrochlorothiazide 12.5-25 mg/die if serum creatinine <2 mg/dl, furosemide 25-75 mg/die if serum creatinin ≥2 mg/dl)

Drug: amlodipine

Therapy for hypertension

- Step 3: amlodipine up to 10 mg/die

Drug: atenolol

Therapy for hypertension

- Step 4: atenolol up to 100 mg/die

Drug: doxazosin

Therapy for hypertension

- Step 5: doxazosin up to 4 mg/die

Drug: clonidine

Therapy for hypertension

- Step 6: clonidine

Drug: insulin

Therapy for Hyperglycaemia (to achieve HbA1c <7):

- insulin

Drug: simvastatin

Therapy for hypercholesterolemia:

- for reducing LDL cholesterol < 100 mg/dl: simvastatin up to 80 mg/die

Drug: fibrate

Therapy for hypertriglyceridemia

- for reducing triglycerides < 150 mg/dl and/or increasing HDL cholesterol > 40-50 mg/dl: a fibrate

Drug: erythropoietin

Treatment of anaemia:

- erythropoietin

Drug: aspirin

Antiplatelet therapy (in all patients without contraindications):

- aspirin up to 160 mg/die
