Abstract: The survival benefit of transplanting hepatitis C (HCV)-positive donor kidneys into HCV-positive recipients remains uncertain. The purpose of this study was to assess the effect of HCV-status of the donor (D) kidney on the long-term outcomes in kidney transplant recipients (R). We evaluated 2169 consecutive recipients of deceased-donor kidney transplants performed between 1991 and 2007. The following HCV cohorts were identified: D-/R- (n = 1897), D-/R+ (n = 59), D+/R- (n = 118), and D+/R+ (n = 95). Patients were followed for a mean of 6.02 (standard deviation = 4.26) yr. In a mulitvariable Cox-proportional hazards model, D+/R+ cohort had significantly lower patient survival (adjusted-hazard ratio [HR] 2.1, 95% CI [1.4-2.9]) with respect to the reference D-/R- group, whereas mortality was not increased in D-/R+ group. The rate of graft loss was increased in both D+/R+ and D-/R+ but was comparable with each other (adjusted-HR 1.8, 95% CI [1.4-2.5]) vs. adjusted-HR 2.0, 95% CI [1.4-2.8], respectively). D-/R+ cohort experienced significantly higher rate of rejection (adjusted-HR 1.7, 95% CI [1.2-2.5]) and chronic allograft nephropathy (adjusted-HR 2.1, 95% CI [1.2-3.7]). Neither donor nor recipient HCV-status impacted the risk of recurrent or de novo GN. Transplanting HCV-positive kidneys as opposed to HCV-negative kidneys into HCV-positive recipients provided similar graft survival but compromised patient survival in the long term.
