BACKGROUND: In kidney transplantation, concerns have been raised regarding increased incidence of viral opportunistic infections in hepatitis C virus (HCV) nucleic acid test (NAT)-negative (-) recipients who received HCV NAT-positive (+) donor kidneys, specifically BK polyomavirus (BKPyV), cytomegalovirus (CMV), and Epstein-Barr virus (EBV). The purpose of this study was to determine the incidence of these three viral opportunistic infections in HCV NAT- recipients who have undergone kidney transplantation with HCV NAT+ donor kidneys at our institution. METHODS: This was an Institutional Review Board-approved, single-center, retrospective case-control study of HCV NAT- kidney transplant recipients with HCV NAT+ donors from 2018 to 2021. The primary outcome was the cumulative incidence of viral infections of BKPyV, CMV, and/or EBV within 1 year following kidney transplantation. RESULTS: A total of 231 patients were included, 77 in the exposed (donor HCV NAT+) group and 154 in the control (donor HCV NAT-) group. The adjusted cumulative incidence of viremia within 1 year did not statistically differ between groups (77% exposed group versus 66% for the control group, hazard ratio 1.34, 95% confidence interval 0.95-1.89). In addition, no statistically significant differences were observed for secondary outcomes with the exception of CMV viremia (62% exposed versus 49% control, p = 0.021). However, there were more patients in the exposed group at high risk for CMV viremia based on serostatus (CMV Donor+/Recipient-, D+/R-). CONCLUSION: Among patients who received HCV NAT+ donor kidneys, no clear association was observed between exposure to HCV NAT+ donor kidneys and viral infections of BKPyV, CMV, or EBV.
