The use of kidneys from hepatitis C virus (HCV)-positive (D+) deceased donors for HCV-negative recipients (R-) might increase the donor pool. We analyzed the national Organ Procurement and Transplant Network (OPTN) registry from 1994 to 2014 to compare the outcomes of HCV D+/R- (n = 421) to propensity-matched HCV-negative donor (D-)/R- kidney transplants, as well as with waitlisted patients who never received a transplant, in a 1:5 ratio (n = 2105, per matched group). Both 5-year graft survival (44% vs 66%; P < .001) and patient survival (57% vs 79%; P < .001) were inferior for D+/R- group compared to D-/R-. Nevertheless, 5-year patient survival from the time of wait listing was superior for D+/R- when compared to waitlisted controls (68% vs 43%; P < .001). Of the 126 D+/R- with available post-transplant HCV testing, HCV seroconversion was confirmed in 62 (49%), likely donor-derived. Five-year outcomes were similar between D+/R- that seroconverted vs D+/R- that did not (n = 64). Our analysis shows inferior outcomes for D+/R- patients although detailed data on pretransplant risk factors was not available. Limited data suggest that HCV transmission occurred in half of HCV D+/R- patients, although this might not have been the primary factor contributing to the poor observed outcomes.
