Abstract: Fifteen patients of idiopathic nephrotic syndrome who failed to respond to 8 weeks of corticosteroid therapy formed the material for this study. There were 10 males and 5 females, age ranging from 4 to 56 years. Three patients had hypertension. Histological lesions were focal and segmental glomerulosclerosis (FSGS) in 8; membranous glomerulonephritis in 3; mesangial proliferative glomerulonephritis in 2 and membranoproliferative glomerulonephritis in 2 patients. Proteinuria ranged from 3.64 to 8.66 g/1.73 m2/day. Serum albumin ranged between 2.2 to 3.3 g/dl. Serum creatinine was elevated > 1.5 mg/dl in 3 cases. After discontinuing steroids, enalapril was started in a dose of 2.5 mg/day and increased by 2.5 mg/day every 3-4 days till the maximum tolerated dose but not exceeding 20 mg/day. Proteinuria, serum albumin and serum creatinine estimations were done every 4 weeks for six months and every three months thereafter. Patients were followed up for 6 to 30 months. Proteinuria decreased to < 1.5 g/1.73 m2/day in 12 patients (80%) and to < 0.5 g/1.73 m2/day in 10 patients (66.7%) by 8 weeks. There was no significant decrease in proteinuria in 3 (20%) patients; two of these were cases of FSGS and one of membranoproliferative glomerulonephritis. Oedema, hypoalbuminaemia and hypercholesterolaemia returned to normal in all patients who had a decrease in the proteinuria. There was no correlation between the histological lesion and response to enalapril. There was no rise in the serum creatinine level above the baseline in any of the patients. Except for cough in one patient, no other significant side effects were observed. We conclude that enalapril is effective in reducing proteinuria and thereby the morbidity in steroid resistant nephrotic syndrome irrespective of the underlying pathology.
