title: Stability of renal allograft recipients after conversion from cyclosporine to azathioprine.
abstract: Forty-eight patients with stable renal function after allotransplantation have been converted from CsA/prednisone to azathioprine/prednisone to assess the short- and long-term effects upon renal function. Virtually all patients show an initial improvement in serum creatinine levels. Three patients developed chronic renal failure after 12 to 21 months, and three died of pneumonia 7, 12, and 19 months later. The mean serum creatinine level at latest follow-up (seven to 36 months) was 2.5 +/- 1.5 mg/dL for all 48 patients. Of interest, a control group of 21 patients not converted to azathioprine had serum creatinine levels of 2.5 +/- 0.8 mg/dL, over a follow-up period of five to 25 months. It is not immediately apparent that either group will have a superior overall outcome, although patients on azathioprine seem to have more of a risk for graft loss. More data are needed with various dosage schedules, and with randomized controls.
