AbstractImmunosuppression can lead to hepatitis B virus (HBV) reactivation in hepatitis B core antigen antibodies (anti-HBc) positive patients, especially those undergoing chemotherapy, although there is limited data on solid organ recipients, especially lung transplantation. Our aim was to analyze the risk of HBV reactivation and the potential impact of anti-HBc-positive status (both donors and recipients) on prognosis in a lung, kidney, and liver transplantation cohort.Retrospective analysis including data from all transplants in adults (2011-2012) in a tertiary hospital, with prospective HBV serology study to assess the risk of reactivation and its possible impact on survival.In total, 392 transplant recipients were included (196 kidney, 113 lung, 83 liver). Pre-transplantation anti-HBc screening was more frequent in liver recipients (P < .001) and donors (P < .001) than in kidney or lung. Fifty-five (14%) recipients were anti-HBc-positive and were not undergoing antiviral prophylaxis. Three (5.4%) cases of HBV reactivation occurred: 2 in pre-transplant anti-HBc-positive recipients and 1 with prior unknown anti-HBc status. All were HBeAg+ with HBV deoxyribonucleic acid (DNA) >10E8 IU/mL and only mild fibrosis. Baseline recipient anti-HBc positive status was the only factor associated with HBV reactivation. No reactivation cases occurred in lung or kidney recipients of anti-HBc positive grafts. Survival was lower in lung transplants, especially in human immunodeficiency virus-infected patients and those with prior immunosuppression.Anti-HBc positive status is a risk factor for HBV reactivation in solid organ recipients. Anti-HBc testing is highly recommended in solid-organ transplant recipients in order to identify those anti-HBc positive and therefore candidates for periodical hepatitis B surface antigen (HBsAg) and HBV DNA screening after transplant.
