The consecutive use of azathioprine and cyclophosphamide after cadaveric renal homotransplantation in a 20 year old male is charted. The change to cyclophosphamide was made because of dissatisfaction with the early postoperative course. There was slow improvement in the subsequent convalescence, but, retrospectively, there is no reason to believe that this might not have occurred even without making the drug switch. The globulin injections were daily for ten days, every other day for 20 days, and twice a week until they were discontinued because of anaphylactic reactions. ALG, Horse antilymphocyte globulin; BUN, blood urea nitrogen level; CCr, creatinine clearance; and WBC, white blood cell count.
