AB To the Editor.—On the surface, the recent article by Abraham and colleagues1 would seem to address a provocative question: whether or not the progression of nondiabetic chronic renal disease can be affected by the administration of the angiotensin-converting enzyme inhibitor (ACEI) enalapril. Closer inspection reveals little data concerning this patient group. Of the 10 patients able to complete short-term therapy, 4 actually had diabetic nephropathy and only 2 of the 6 patients with nondiabetic renal disease had significant proteinuria (Nos. 4 and 10). Only 1 of these 2 patients (No. 4) seemed to have a significant reduction in proteinuria, but he was withdrawn from the study before the long-term phase of the study could be completed. The authors state that "the rate of progression of renal insufficiency seemed to slacken in 3 of 4 patients with diabetic nephropathy," based on changes in slopes of serum creatinine curves (the
