✦ Synopsis

Despite significant improvements in the results of renal transplantation since the introduction of cyclosporin, graft loss beyond the 1st year remains a significant and unresolved problem. In a retrospective analysis, 348 cyclosporin-treated renal transplant recipients with a functioning graft at 12 months were studied. Forty-eight patients in whom graft failure occurred in the 2nd and 3rd years were compared to 300 patients who maintained graft function beyond this time. Both groups were comparable with respect to donor and recipient features. Factors reflecting recipient immunological responsiveness--sensitization, previous transplantation and early rejection episodes--continued to affect graft survival beyond the 1st year. Surprisingly, there was a higher incidence of prior transfusion in the group with graft failure in the 2nd and 3rd years than in those with longer function (65% vs 24%). Serum creatinine levels at 3 and 6 months were also predictive of graft loss amongst patients with a functional graft at 1 year. It remains to be answered whether new immunosuppressive drugs and strategies will overcome these risks for late graft loss.
