Cyclosporin A in steroid-sensitive nephrotic syndrome with frequent relapses.

Eight patients with steroid-sensitive nephrotic syndrome which frequently relapsed despite cyclophosphamide treatment were given cyclosporin A (7.5 mg/kg/day to 10 mg/kg/day) for 8 to 12 weeks. Six had minimal change glomerulonephritis and two had focal segmental glomerulonephritis. Cyclosporin A was given to 5 patients when their nephrotic syndrome was in relapse and to 3 patients when the nephrotic syndrome was in remission. Cyclosporin A induced a transient remission in only one patient.
