Aboriginal populations experience a very high rate of end-stage renal disease (ESRD); however, little is known about the outcomes of transplantation in this population. We performed a retrospective database review to determine the short- and long-term outcomes of kidney transplantation in Aboriginals. Adult Aboriginal (AB) and Caucasian (C) individuals receiving primary kidney transplants between 1969 and 2003 in Manitoba, Canada were examined. A total of 705 recipients were included (126 AB and 579 C). AB recipients were younger, had different etiologies of ESRD, longer cold-ischemic times for deceased donor transplants, and higher peak panel reactive antibody levels. At 1 year post-transplant, there was no difference in serum creatinine, acute rejection or graft survival between AB and C recipients. However, AB recipients experienced greater weight gains early post-transplant and were more likely to develop post-transplant diabetes mellitus. AB recipients exhibited inferior 10-year graft (AB 26% vs. C 47%, p < 0.01) and patient survival (AB 50% vs. 75%, p < 0.01). When graft survival was censored for death with a functioning graft, there was no difference between the two groups. Multivariate analysis revealed AB race to be an independent predictor of premature graft failure and patient death. In conclusion, kidney transplant outcomes have historically been inferior in the Manitoba population of Canadian Aboriginals.
