title: Enalapril improved renal function and proteinuria in chronic glomerulopathies.
abstract: Ten patients (6 men, 4 women, age range 35-64 years) with glomerulopathies were studied. Diagnoses were membranoproliferative glomerulonephritis (GN; n = 4), membranous GN (n = 3), focal and diffuse glomerulosclerosis (n = 2), and poststreptococcal GN (n = 1). These were confirmed by renal biopsy in 8 of the 10 patients. All patients had reduced function (creatinine clearance 15-55 ml/min); proteinuria ranged from 1.0 to 10.4 g/day. Three normotensive patients received enalapril 10 mg once daily. Seven hypertensives received enalapril 10-40 mg once daily to control blood pressure (BP). Concomitant diuretic therapy (furosemide/bumetanide) was administered to 6 patients. There were visits every 14 days for a mean of 15.9 months (range 9-26 months). Diet was monitored, and BP was significantly controlled in the hypertensive patients but not altered in the normotensives. Serum creatinine, blood urea nitrogen, creatinine clearance, and 24-hour urinary protein improved and did not deteriorate progressively. Serum potassium did not change significantly. No adverse clinical events were noted. Enalapril therapy may improve the prognosis for GN over time by maintaining glomerular filtration rate and decreasing proteinuria.
