Abstract

Objectives. Living-unrelated donors may become an additional organ source for patients on the kidney waiting list. We studied the impact of a combination of calcineurin inhibitors and mycophenolate-mofetil together with steroids on the outcomes of living-related (LRD), unrelated (LUR), and cadaver transplantation. Methods. Between September 1997 and January 2000, 129 patients underwent LRD (n = 80) or LUR (n = 49) kidney transplantation, and another 173 patients received a cadaveric kidney. Immunosuppressive protocols consisted of mycophenolate-mofetil with cyclosporine-Neoral (41%) or tacrolimus (59%) plus steroids. We compared the patient and graft survival data, rejection rate, and graft functional parameters. Results. LRD recipients were younger (33.6 years) than LUR (47.8 years) and cadaver (43.7 years) donor recipients (P <0.001). HLA matching was higher in LRD patients (P <0.001). Acute rejection developed in 28.6% of LUR versus 27.5% of LRD transplants and 29.7% of cadaver kidney recipients (P = not significant). The creatinine level at 1, 2, and 3 years after transplant was 1.63, 1.73, and 1.70 mg% for LRD patients; 1.48, 1.48, and 1.32 mg% for LUR patients; and 1.75, 1.68, and 1.67 mg% for cadaver kidney recipients (P = not significant), respectively. No difference in patient survival rates was found among the groups. The 1, 2, and 3-year graft survival rates were significantly better in recipients of LRD (91.3%, 90.0%, and 87.5%, respectively) and LUR transplants (89.8%, 87.8%, and 87.8%, respectively) than in cadaver kidney recipients (81.5%, 78.6%, 76.3%, respectively; P <0.01). Conclusions. Despite HLA disparity, the rejection and survival rates of LUR transplants under current immunosuppressive protocols are comparable to those of LRD and better than those of cadaveric transplants.
