Triple Blockade of the Renin Angiotensin Aldosterone System in Diabetic (Type 1&2) Proteinuric Patients

October 24, 2013 updated by: Pete Antonopoulos, John H. Stroger Hospital

Study of Triple Blockade of the Renin Angiotensin Aldosterone System (RAAS) in Diabetic (Type 1&2) Proteinuric Patients With (ACE-, ARB, DRI)

Study Hypothesis:

Reduction in albuminuria has been shown to decrease progression of diabetic

nephropathy. In diabetic nephropathy patients treated with maximal

antihypertensive doses with dual RAAS blockade (total daily dose valsartan 320

mg and either enalapril 40 mg or benazepril 40 mg daily, or losartan 100mg), persistent

albuminuria reflects further additional RAAS activation. Microvascular renal

disease due to increased RAAS activation may be more effectively treated with

triple blockade by the addition of a direct renin inhibitor (DRI) Aliskiren.
