Hepatitis C virus (HCV) infection is common among patients receiving chronic dialysis. However, few studies have examined both survival on dialysis as well as transplantation outcomes for HCV-seropositive patients, partly due to lack of information about HCV-serostatus in large registry datasets.
Methods: We performed a retrospective cohort study for patients receiving hemo- and peritoneal dialysis between 1/1/2004 – 12/31/2014. We linked detailed data that included HCV antibody serostatus from a national dialysis provider with transplant registry data from the Organ Procurement and Transplantation Network. We used Cox and cause-specific hazards regression to determine hazard ratios (HRs) of all-cause mortality, kidney transplant wait-listing, and kidney transplantation associated with HCV seropositivity.
Results: Among 442,171 dialysis patients, 31,624 (7.2%) were seropositive for HCV. HCV seropositivity was associated with a small elevation in the risk of death (aHR 1.09, 95% CI 1.07-1.11) but a substantial reduction in access to the kidney transplant waitlist (sHR 0.67, 95% CI 0.61 – 0.74). Once waitlisted, HCV-seropositive patients underwent transplantation as rapidly (sHR 1.10, 95% CI0.96-1.27) as HCV-seronegative patients. Compared to remaining on dialysis, HCV-seropositive patients lived longer with kidney transplantation, with better survival evident by 9 months after transplant. Importantly, as in Figure 1, the strategy of accepting an HCV-seropositive donor kidney (HCV+D) provided a survival advantage by 2 years compared to the option of remaining on the waitlist or receiving an HCV-negative donor kidney.
Conclusion: HCV-seropositive dialysis patients with HCV have reduced access to the kidney transplant waitlist, despite deriving a significant survival benefit from transplantation. These patients and their physicians should carefully consider the benefits of accepting kidneys from donors with HCV.
