Randomized Controlled Trial Clinical Trial
A single institution, randomized, prospective trial of cyclosporin versus azathioprine-antilymphocyte globulin for immunosuppression in renal allograft recipients.
Between September 26, 1980 and December 31, 1983, 230 splenectomized, transfused renal allograft recipients were randomized to treatment with either cyclosporin-prednisone (N = 121, 68 diabetic and 53 nondiabetic recipients; 73 cadaver and 48 related donor grafts) or azathioprine-prednisone-antilymphocyte globulin (N = 109, 61 diabetic and 48 nondiabetic recipients; 69 cadaver and 40 related donor grafts). The results were analyzed on March 31, 1984. Actuarial patient survival rates at 2 years were 88% in the cyclosporin and 91% in the azathioprine groups (p = 0.649). ⋯ D.) serum creatinine levels (mg/dl) at 1 year were higher in cyclosporin (2.0 +/- 0.6) than in azathioprine (1.5 +/- 0.5) treated recipients (p = less than 0.001). A reduction in cyclosporin dose because of nephrotoxicity was required in 96 of the cyclosporin-treated patients (70%), and 25 were switched to treatment with azathioprine (21%). The incidence of all infections in cyclosporin-treated patients was approximately half of that in azathioprine-treated patients, and only nine per cent of the cyclosporin-treated patients were diagnosed to have cytomegalovirus infections during the first post-transplant year vs. 28% in azathioprine-treated patients (p = 0.002).(ABSTRACT TRUNCATED AT 400 WORDS)
