The effect of angiotensin-converting-enzyme inhibition on diabetic nephropathy.

TLDR
Whether captopril has kidney-protecting properties independent of its effect on blood pressure in diabetic nephropathy is determined.
Abstract
Background Renal function declines progressively in patients who have diabetic nephropathy, and the decline may be slowed by antihypertensive drugs. The purpose of this study was to determine whether captopril has kidney-protecting properties independent of its effect on blood pressure in diabetic nephropathy. Methods We performed a randomized, controlled trial comparing captopril with placebo in patients with insulin-dependent diabetes mellitus in whom urinary protein excretion was ≥ 500 mg per day and the serum creatinine concentration was ≤ 2.5 mg per deciliter (221 μmol per liter). Blood-pressure goals were defined to achieve control during a median follow-up of three years. The primary end point was a doubling of the base-line serum creatinine concentration. Results Two hundred seven patients received captopril, and 202 placebo. Serum creatinine concentrations doubled in 25 patients in the captopril group, as compared with 43 patients in the placebo group (P =0.007). The associated reductions in risk...

TL;DR: In this article, a unified approach to fitting two-stage random-effects models, based on a combination of empirical Bayes and maximum likelihood estimation of model parameters and using the EM algorithm, is discussed.

TL;DR: Captopril protects against deterioration in renal function in insulin-dependent diabetic nephropathy and is significantly more effective than blood-pressure control alone.
