Effect of ACE inhibitors on proteinuria and renal functioning in primary glomerulopathies]

Angiotensin converting enzyme inhibitors was given to 16 patients with glomerular nephritis in whom a complete remission of nephrotic syndrome could not be achieved with immunosuppressive-anti-inflammatory therapy. Captopril in the daily dose of 25-75 mg and enalapril in the daily dose of 10 mg were administered for 1-36 months (mean 12.6 months). Daily proteinuria decreased by 40-80% comparing with baseline value in 2/3 of patients. Total protein and albumin serum levels increased simultaneously. No changes in blood creatinine were noted in patients with initially normal renal functioning except one patient. Renal functioning was stable in 50% of patients with increased blood creatinine levels (mean 200 mumol/L). Blood creatinine was increasing in the remaining patients.
