Objective  To evaluate the association between N-acetyltransferase 2 (NAT2) gene polymorphisms and the risk of antituberculosis drug-induced liver injury (ATDILI). Methods  We searched the PubMed, Embase, Wanfang, China National Knowledge Internet and VIP databases to find case-control studies, with the last updated search being performed on June 2017. Odds ratio (OR) with 95% confidence interval (CI) was calculated to evaluate the strength of association. Results  A total of 29 studies, involving 1 382 cases and 5 967 controls were included. The results of the Meta-analysis indicated that NAT2 slow acetylators were associated with increased risk of ATDILI compared with fast and intermediate acetylators [OR=3.08, 95%CI (2.44, 3.88), P<0.000 01]. Similar results were also found in subgroup analysis when stratified by ethnicity, isoniazid dosage and diagnostic criteria of ATDILI. Conclusion  Individuals with NAT2 slow acetylators may have increased risk of ATDILI.
