Kidney transplantation and waitlist mortality rates among candidates registered as willing to accept a hepatitis C infected kidney

Academic Article


  • Background: HCV-infected (HCV+) ESRD patients derive significant survival benefit from kidney transplantation (KT) over remaining on dialysis. Given high mortality rates on dialysis and the unique ability to accept HCV+ and HCV- donor kidneys, understanding their access to KT is essential. Methods: Three thousand nine hundred and sixty-three adult kidney-only candidates reported as willing to accept an HCV+ kidney from 2008 to 2014 were identified and assumed to be HCV+. Time-at-risk began at date of listing. Cumulative incidence of transplant and waitlist mortality were assessed using competing risks, and separate mixed effects Cox proportional hazards models were used to examine waitlist mortality and transplantation rates. All models were adjusted for candidate demographic and clinical characteristics with a random effect for listing organ procurement organization with nested listing center. Results: HCV+ candidates were commonly older (>50¬†years: 82.6%), African American (52.8%), and male (73.6%). Five years after listing, 35.5% of candidates were transplanted with an HCV+ donor kidney, 9.7% transplanted with an HCV- donor kidney, and 23.6% died on the waitlist. Overall transplant rates exceeded waitlist mortality rates (22.69 vs 11.45 per 100 person-years [PY]), largely driven by transplantation with HCV+ donor kidneys. Utilization of HCV+ donor kidneys was associated with increased transplantation rate (17.72 per 100 PY), while rate of transplant with HCV- donor kidneys was much lower (4.97 per 100 PY) than waitlist mortality (11.45 per 100 PY). Conclusion: In light of effective HCV therapies, it may be prudent to institute strategies to decrease waiting time and waitlist mortality for HCV+ candidates by increasing utilization of HCV+ donor kidneys.
