BackgroundHepatitis C virus (HCV) infection has been deemed detrimental to kidney transplantation (KT) outcomes. Breakthrough HCV treatment with direct-acting antiviral (DAA) medications improved the probability of HCV+ kidney use for KT even in noninfected (HCV-) recipients. We hypothesized that recipient HCV infection influences deceased donor KT outcomes, and this effect could be modified by donor HCV status and use of DAAs.Study DesignWe conducted a retrospective cohort study based on data from the Organ Procurement and Transplantation Network as of September 2018. A mate kidneys analysis was performed with HCV+ and HCV- recipients of solitary adult KT from ABO-compatible deceased donor between January 1994 and June 2018. We selected donors where 1 KT recipient was HCV+ and the mate kidney recipient was HCV-. Both HCV- and HCV+ donors were identified and analyzed separately. Outcomes, including survival of patients, grafts, and death-censored grafts, were compared between the groups.ResultsFour-hundred and twenty-five HCV+ and 5,575 HCV- donor mate kidneys were transplanted in HCV-discrepant recipients. HCV+ recipients of HCV- donor had worse patient and graft survival (adjusted hazard ratio 1.28; 95% CI, 1.19 to 1.37 and adjusted hazard ratio 1.26; 95% CI 1.18 to 1.34, respectively) and death-censored grafts (adjusted hazard ratio 1.24; 95% CI, 1.15 to 1.34) compared with HCV- recipients. Comparable patient and graft survival and death-censored grafts were found in recipients of HCV+ donors, regardless of recipient HCV status. The risk associated with HCV positivity in donors or recipients in the pre-DAA era (before December 2013) was no longer statistically significant in the post-DAA era.ConclusionsGiven comparable outcomes between HCV+ and HCV- recipients in post-DAA era or when receiving HCV+ donor kidneys, broader use of HCV+ kidneys regardless of the recipient's HCV status should be advocated, and allocation algorithm for HCV+ kidneys should be revised.Copyright © 2020 American College of Surgeons.
