ABSTRACT
Liver transplantation (LT) with hepatitis B core antibody (anti-HBc) positive grafts to hepatitis B surface-antigen (HBsAg) negative recipients is safe and has likely contributed to improvements in organ access over the years. The incidence of de novo hepatitis B infection (HBV) in these instances is low with appropriate prophylaxis and is affected by recipient immunologic status. There is debate as to whether hepatitis B surface antibody (anti-HBs) positivity may safely inform prophylaxis discontinuation post-LT. In this retrospective study of all hepatitis B surface antigen (HBsAg) negative recipients of anti-HBc positive organs at three large academic centers between January 2014 and December 2019, nine LT recipients discontinued prophylaxis after developing anti-HBs antibodies 1 year or later post-LT. Three of the nine patients (33%) developed de novo HBV, defined by positive HBsAg or hepatitis B virus (HBV) DNA, during the study period. The remaining six patients had no evidence of HBV infection after a mean follow-up of 37 months. The patients without de novo HBV had higher anti-HBs titers at the time of prophylaxis discontinuation and were less likely to have negative anti-HBs at the time of transplant or negative anti-HBc at any time point. These results suggest that quantitative anti-HBs titer thresholds rather than qualitative anti-HBs positivity at 1 year or later after LT should be used to identify patients at decreased risk of de novo infection and help guide prophylaxis duration.
