Kidney transplantation from living-unrelated donors: comparison of outcome with living-related and cadaveric transplants under current immunosuppressive protocols
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.
