Abstract

There has been concern that cyclosporine's nephrotoxicity increases the incidence of delayed graft function (DGF), prolongs periods of oliguria, and reduces graft survival. In order to further study whether CsA should be used in DGF, we conducted a randomized prospective trial of the effect of CsA versus antilymphocyte globulin on the effects of DGF. Between 12/22/85 and 3/11/88, all patients with DGF after an initial 12-24 hr of CsA were randomized to either daily Minnesota ALG and prednisone or lower-dose CsA (10 mg/kg/day) and prednisone. Resolution of DGF was defined as a lack of dialysis dependency and a 25% fall in the serum creatinine (CR). If DGF was not resolved by 2 weeks, transplant renal biopsies were performed to assess the presence of occult rejection. CsA (10 mg/kg/day) was initiated in the ALG group only after resolution of the DGF. Of the 45 patients who recovered graft function, 19 received ALG and 26 received CsA. CsA significantly prolonged the duration of DGF (ALG 9.74 days, CsA 13.69 days, P = 0.035) but did not result in a prolongation of hospitalization. No difference in CR was found between the two groups at 1 month, 3 months, 6 months, or 12 months. Mean CR at 12 months was 1.98 mg/dl for ALG versus 1.96 mg/dl for CsA. Overall graft survival did not differ in the CsA and ALG groups (P = 0.33). CsA does slightly increase the duration of DGF as compared with ALG but has no effect on one-year serum CR or one-year graft survival. Since there appeared to be no harmful long-term effects of the slight lengthening of DGF, a lower-dose of CsA protocol with biopsy surveillance for occult rejection can be used in patients with DGF.
