<![CDATA[Background: Tuberculosis is still one of the leading causes of poor health and death worldwide. Drug-induced liver injury (DILI) is an important and serious side effect of anti-tuberculosis treatment and can cause non-adherence of patients to the treatment. To reduce the possibility of patients developing DILI, the risk factors must be identified. Methods: This systematic review was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 statement. Inclusion and exclusion criteria were used to screen and filter the articles that were obtained from literature searching performed through several journal databases. The extracted data were analyzed qualitatively and quantitatively. The quality of each study was also assessed using the modified Newcastle Ottawa Scale (NOS). The protocol for this systematic review has been registered with PROSPERO CRD42022384892. Results: The results showed that, of the 13 studies analyzed qualitatively, 11 studies with a total of 4,920 patients were selected for quantitative analysis. The factors analyzed and the results were female gender (OR=1.10; 95% CI=0.72-1.67; P=0.65), age over 40 years (OR=1.60; 95% CI=1.04-2.46; P=0.03), body mass index less than 18.5 kg/m2 (OR=0.96; 95% CI=0.52-1.79; P=0.9), active smoking (OR=0.71; 95% CI=0.34-1.49; P=0.36), frequent alcohol intake (OR=1.44; 95% CI=0.61-3.42; P=0.41), hepatitis B (OR=3.42; 95% CI=1.72-6.79; P<0.001]), and hepatitis C (OR=12.87; 95% CI=6.67-24.86; P<0.00001]). Conclusion: In conclusion, the evidence from this review suggests that older age, hepatitis B, and hepatitis C are significant risk factors thought to increase the incidence of DILI in active pulmonary tuberculosis patients taking first-line anti-tuberculosis regimens.]]>
