Abstract
Background
Hepatitis B surface antigen (HBsAg)-negative/hepatitis B core antibody (HBcAb)-positive patients with undetectable serum hepatitis B virus (HBV) DNA have experienced and resolved hepatitis B virus (HBV) infection. Lymphoma patients with resolved HBV infection have high risk of HBV reactivation when treated with robust immunosuppressive agents, but the reported rate varies extensively between different studies. This study aims to estimate the risk of HBV reactivation in HBsAg-negative/HBcAb-positive patients receiving rituximab-containing chemotherapy for lymphoma.
Methods
Databases were searched for papers published in English until 8 August 2016. The pooled risk of HBV reactivation was estimated using a random-effects model.
Results
Data from 15 studies were retrieved, including a total of 1312 HBsAg-negative/HBcAb-positive lymphoma patients treated with rituximab-containing chemotherapy. The results revealed HBV reactivation rate of 9.0 % [95 % confidence interval (CI) 0.05–0.15]. In subgroup analysis, the reactivation rates for prospective and retrospective studies were 17 % (I
2 = 87.3 %; 95 % 0.08–0.39, p < 0.001) and 7 % (I
2 = 43.1 %; 95 % CI 0.05–0.11, p = 0.07), respectively.
Conclusions
This meta-analysis confirms a measurable and potentially substantial risk of HBV reactivation in HBsAg-negative/HBcAb-positive patients with rituximab treatment for lymphoma. Prophylactic use of anti-HBV agents should be seriously considered for such patients.
