BACKGROUND: Antituberculosis drug-induced liver injury (ATDILI) is a major safety concern for the treatment of tuberculosis (TB). The impact of chronic hepatitis B infection (CHBI) on the risk of ATDILI is still controversial. In this study, we aimed to assess systematically the influence of CHBI on the susceptibility to ATDILI. METHODS: We reviewed all English-language medical literature with the medical subject search headings hepatitis B and antitubercular agents from the major medical databases. Thereafter, a systematic review and meta-analysis was performed on those publications that qualified. RESULTS: A total of 938 citations were retrieved on the initial major database search, from which 15 studies were determined to be eligible for analysis. While undergoing anti-TB treatment, 575 cases with drug-induced liver injury (DILI) and 4128 controls without DILI were enrolled into this analysis. The pooled odds ratio of all studies for the CHBI to ATDILI was 2.18 (95% confidence interval, 1.41-3.37). Among the studies with a strict definition of DILI (alanine aminotransferase > 5 × upper limit of normal value) and combination anti-TB regimen, the impact of CHBI on ATDILI was significant only in the prospective studies (odds ratio, 3.41; 95% confidence interval, 1.77-6.59), but not in the case-control studies. However, in the studies with a strict definition of DILI and isoniazid only treatment, the association between CHBI and ATDILI was not statistically significant. CONCLUSION: This meta-analysis suggests that CHBI may increase the risk of ATDILI in the standard combination therapy for active TB. Close follow-up and regular liver test monitoring are mandatory to treat TB in chronic hepatitis B carriers.
