YR 1991 UL http://www.ccjm.org/content/58/2/184.abstract AB Chronic renal insufficiency is a progressive, self-perpetuating process which is influenced in part by activation of the intrarenal renin-angiotensin system. Oral angiotensin-converting enzyme inhibitors are being studied in animals and humans to determine whether they slow the decline in renal function characteristic of progressive renal disease. In animals that have reduced renal mass, streptozotocin-induced diabetes mellitus, or puromycin aminonucleoside nephrosis, these agents can reduce proteinuria, decrease the frequency of sclerotic glomeruli, and normalize intrarenal hemodynamics. They also may decrease glomerular hypertrophy that occurs after renal ablation. In human trials, angiotensin-converting enzyme inhibitors decrease proteinuria by altering the glomerular capillary permeability. The effect of these agents on progressive disease may be influenced by how soon therapy is begun and how long it is continued.
