Influence of donor and recipient hepatitis B virus infection on long‐term outcomes after kidney transplantation

Abstract

The demand for transplantable kidneys continues to outstrip supply, and the risk of donor-derived infection limits utilization. The effect of donor or recipient HBV status, defined by surface antigen (HBsAg) positivity, on long-term survival outcomes of kidney transplant (KT) is unknown. We conducted a retrospective cohort study based on Organ Procurement and Transplantation Network (OPTN) data from 2000 to 2019. We identified three cohorts based on donor (D) or recipient (R) HBsAg status: D-R, D-R+, and D+R-. Pairwise comparisons of patient survival (PS) and all-cause graft survival (GS) after propensity score matching were performed to assess the effect of HBV infection in KT recipients. Our findings showed that there were no statistically significant differences in PS and GS among D-R, D-R+, and D+R-groups, nor was the patient or GS different between donor and recipient HBsAg+ status. Finally, in 2019 kidney discard rates were 15% higher for HBsAg+ deceased donors compared to HBsAg- donors. HBsAg+ status was not associated with worse PS or GS after KT. Prior to broadly advocating utilization of HbsAg+ kidneys, further studies assessing KT recipient morbidity and safety are necessary.
