A case of living-donor renal transplantation for chronic renal failure caused by secondary amyloidosis.

Abstract In Japan, amyloidosis is a rare cause of renal failure and of renal transplantation. We treated a patient who underwent a renal transplantation because of chronic renal failure caused by secondary amyloidosis with a good result. The patient was a 50-year-old woman who was diagnosed with secondary amyloidosis and an amyloid kidney. She underwent living donor renal transplantation after about 7 years of hemodialysis. During the 3-year posttransplantation period, she maintained good allograft function with a serum creatinine level about 1.2 mg/dL. Because of amyloidosis is a systemic disease, amyloid kidney patients often experience fatal complications, so the indications for renal transplantation in amyloid patients are still controversial. But if the patient's general condition is good, renal transplantation can be an effective therapy for patients with kidney failure caused by amyloidosis.
