title: Chronic hepatitis B infection and risk of antituberculosis drug-induced liver injury: Systematic review and meta-analysis.
abstract: 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.
  
  
  CONCLUSIONS
  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.
