Treatment of nephrotic syndrome associated with idiopathic rapidly progressive glomerulonephritis and cyclosporin A.

Recent reports suggest that cyclosporin A is beneficial in inducing remission of idiopathic nephrotic syndrome. Nephrotic syndrome is seen in 10-30% of patients with rapidly progressive glomerulonephritis. We report a case of a 69-year-old man with nephrotic syndrome, associated with idiopathic rapidly progressive glomerulonephritis, who was treated initially with corticosteroid and cyclophosphamide. Three months later he developed thrombophlebitis and leucopenia and cyclophosphamide was suspended. Relapse of nephrotic syndrome associated with rapidly progressive glomerulonephritis developed and therapy with cyclosporin A was used with a good response.
