Özet

Objectives: Hepatitis B virus reactivation, particularly when occurring under immunosuppressive therapy, poses a risk for patients with chronic or resolved hepatitis B virus infections. This study aimed to evaluate the incidence and clinical outcomes of hepatitis B virus reactivation in kidney transplant recipients with resolved hepatitis B virus infection. Materials and Methods: We retrospectively screened patients who underwent kidney transplant between 2012 and 2023 seen at our center (Izmir, Türkiye). We included transplant recipients with resolved hepatitis B virus infection. We analyzed risk factors associated with reactivation and the clinical course of patients who developed hepatitis B virus reactivation. Results: Our analyses included 95 kidney transplant recipients; mean follow-up period was 70 ± 31 months. Baseline serology revealed that 9.4% of patients had isolated anti-HBc positivity, whereas 90.6% were positive for both anti-HBc and anti-HBs. None of the patients received antiviral prophylaxis at baseline; however, 14 patients received prophylaxis during the follow-up period. Among the 81 transplant recipients who did not receive prophylaxis, hepatitis B virus reactivation occurred in 3 patients (3.7%). No serious adverse outcomes, such as liver failure, liver transplant, or death due to hepatitis B virus reactivation were observed. Conclusions: Although hepatitis B virus reactivation is uncommon in hepatitis B surface antigen-negative/ anti-HBc-positive patients after kidney transplant, reactivation remains a potential risk. In patients not scheduled for long-term prophylaxis, careful assessment regarding the necessity, efficacy, and safety of antiviral intervention is critical for optimal management.
