    Abstract:
    To determine whether the increase in proteinuria resulting from high dietary protein intake could be prevented by angiotensin-converting enzyme inhibition (ACEI), we performed paired studies on 8 nephrotic patients with normal GFR. They were fed sequential diets with a protein content of 0.8 (LPD) and 1.6 g/kg BW (HPD) each for 8 weeks. Patients on HPD received enalapril (ENAL) 10 mg/day. Despite the significant difference in protein intake, urinary protein excretion, at the end of the two dietary periods, was not statistically different. However, total serum protein and serum albumin increased significantly with HPD + ENAL treatment. The capability of ACEI to prevent the increase in proteinuria induced by HPD may be due to changes in glomerular hemodynamics, possibly mediated by changes in the activity of angiotensin II. Our study indicates that protein metabolism in nephrotic patients is better maintained with HPD + ENAL than with LPD alone.
