Background: Hepatitis B virus (HBV) reactivation is associated with complications and adverse outcomes in patients with clinically resolved HBV infection who are seronegative for hepatitis B surface antigen (HBs Ag), and seropositive for hepatitis B core antibody (HBc Ab) and/or hepatitis B surface antibody (HBs Ab) before kidney transplantation (KT). Methods: We retrospectively analyzed 52 patients with resolved HBV infection who were HBV-DNA negative. HBV-DNA after KT was evaluated, and the occurrence of HBV reactivation and outcomes were monitored. We defined HBV reactivation as seropositivity for HBV-DNA at or above the minimal detection level of 1.0 log IU/mL and treated preemptively (using entecavir) when the HBV-DNA level was at or above 1.3 log IU/mL, in accordance with the Japanese Guidelines for HBV treatment. Results: Among the 52 patients, the mean age was 57.2 ± 10.8 years. The median HBc Ab titer was 12.8 (interquartile range, 4.6-42.6) cutoff index, and five (9.6%) cases of HBV reactivation occurred. No patients developed graft loss and died due to HBV reactivation. Statistical analysis showed that age and HBc Ab titer were significant risk factors for HBV reactivation (P =.037 and P =.042, respectively). No significant differences were found between graft survival and the presence or absence of HBV reactivation. Conclusion: These results suggest that HBc Ab titer and age could be significant risk factors for HBV reactivation. Resolution of HBV infection did not appear to be associated with patient or graft survival, regardless of whether HBV reactivation occurred, when following our preemptive strategy.
