OBJECTIVE: The purpose of this study was to evaluate the basis for the racial/ethnic disparity in kidney allograft survival.
METHODS: We conducted a retrospective study of 2130 patients who underwent kidney transplantation between January 1995 and December 2003. Patient and graft survivals were compared using Kaplan-Meier analysis.
RESULTS: Black recipients were more likely than white recipients to have hepatitis C infection (24.6% vs 7.1%), current tobacco use (21.2% vs 13.1%), previous alcohol use (22.6% vs 9.7%), and past illicit drug use (13.6% vs 3.9%). Current employment was less common among blacks. Additionally, black recipients were more likely to have a prior kidney transplant (16.7% vs 11.0%) and to have a cadaver kidney donor (74% vs 56.5%). The 5-year allograft survival rate was 72% for whites and 59% for blacks (p < .01). Previous kidney transplantation, cadaveric donor, donor age, recipient employment status, and recipient tobacco use were associated with allograft survival in a Cox proportional hazard model.
CONCLUSIONS: Graft survival rate in black kidney transplant recipients is significantly lower than whites, and this disparity can be partially explained by the low rate of live donors and a higher previous transplantation rate in blacks.
