title: [A decrease in urinary proteins in an elderly patient with refractory minimal change nephrotic syndrome administration of an angiotensin converting enzyme inhibitor in combination with steroids].
abstract: A 72-year-old woman had been treated for hypertension and hyperthyroidism by a local doctor. In May 1998, she came to this institution with a chief complaint of leg edema. Based on the clinical findings, she was diagnosed as having nephrotic syndrome with massive proteinurea, hypoproteinemia and hyperlipidemia. Renal biopsy findings showed minimal change nephrotic syndrome (MCNS). No substantial improvement was obtained by steroid therapy. We therefore additionally administered angiotensin-converting enzyme inhibitor (enalapril maleate). The urinary protein concentration significantly decreased. On decreasing the dose of steroids, the urinary protein concentration increased. Cyclophosphamide helped us to decrease the steroid dosage. This treatment resulted in type II incomplete remission. The final diagnosis was refractory MCNS. During steroid therapy, she developed hyperglycemia. She had no histology of diabetes mellitus. There is therefore a possibility that steroids can induce hyperglycemia even in patients without a history of diabetes mellitus. These results suggest that careful monitoring of plasma glucose is necessary during steroid therapy and that the administration of an angiotensin-converting enzyme inhibitor is effective in elderly patients with refractory primary nephrotic syndrome.
