Hepatitis B core antibody-positive (HBcAb+) graft is known as a risk for de novo hepatitis B virus (HBV) infection in recipients after liver transplantation (LT). However, little is known about the possibility or incidence of de novo HBV infections after LT in hepatitis B surface antigen-negative (HBsAg-)/HBcAb+ recipients using HBsAg-/HBcAb- grafts. The study aimed to evaluate the prevalence of de novo HBV infection in HBsAg-/HBcAb+ recipients using HBsAg-/HBcAb- grafts. A retrospective review was performed with the records of 1129 adult patients who underwent primary LT at a single institution in an HBV endemic area between January 2000 and December 2013. A total of 78 patients (6.9%) were reviewed for de novo HBV infection after LT. De novo HBV infection was developed in 1 patient (1.28%). The patient was a 65-year-old woman who underwent LT due to alcoholic liver cirrhosis. De novo HBV was not related to graft loss or death and well treated with tenofovir. In conclusion, de novo HBV infections may occur in HBsAg-/HBcAb+ recipients using HBsAg-/HBcAb- grafts, and caution is needed in these patients.
