Effects of cyclosporine, azathioprine and prednisone on Kimura's disease and focal segmental glomerulosclerosis in renal transplant patients.

Nephrotic syndrome secondary to focal segmental glomerulosclerosis (FSGS) is a common cause of renal failure leading to transplantation. Various immunosuppressive drugs, including cyclosporine, have been used in the treatment of FSGS with varying degrees of success. The patient described herein was afflicted with end stage renal disease secondary to steroid-resistant nephrotic syndrome due to FSGS with coexistent Kimura's disease. After kidney transplantation, the patient experienced a remission of both the Kimura's disease and the nephrotic syndrome in the native kidneys, leading to the resumption of renal function by the native kidneys in spite of severe transplant glomerulopathy. This case suggests that certain cases of FSGS without extensive interstitial disease may benefit from aggressive treatment with a combination of immunosuppressive drugs.
