We have studied the long term effects of captopril therapy on proteinuria in ten patients with non-insulin-dependent diabetes mellitus with hypertension and nephropathy. There were 7 males and 3 females, with a mean age of 53.3 ± 10.6 years. After a run-in period of two weeks, therapy with captopril was started. The following parameters were studied: serum glucose, sodium, potassium, cholesterol and triglycerides, glycosylated haemoglobin, renal function and 24 hour urine protein excretion before and at six month intervals for up to 24 months. Average BP fell significantly from 182.5 ± 28/95 ± 7.1 to 146 ± 16.7/76 ± 18.1 mmHg although no significant changes were seen in the biochemical parameters studied, except a reduction in 24 hour urine protein excretion from 3.86 ± 2.85 to 0.88 ± 1.08 g/24 h after 24 months of treatment (P < 0.01). No correlation was observed between the reduction in proteinuria and any other parameters studied. Our results confirm the reduction of proteinuria in patients with type II diabetes mellitus and stable diabetic nephropathy treated with captopril. This effect was maintained for a period of 24 months.
