RESUMEN
The study analyzes the risk factors associated with antituberculosis drug-induced liver injury (ATB-DILI), and the relationship between ATB-DILI and NAT2 gene polymorphisms. Out of the 324 included patients, 57 (17.59%) developed ATB-DILI. Age, history of liver disease, alcohol consumption and timing of antituberculosis (ATB) treatment were independent risk factors for ATB-DILI in the patients with tuberculosis (TB; p < 0.05). There was a significant difference in the distribution of NAT2 metabolic phenotypes between the study group and the control group (p < 0.05). The ATB drug treatment for pulmonary TB can cause a high incidence of ATB-DILI. Age, history of liver disease, alcohol consumption and timing of ATB treatment are independent risk factors for ATB-DILI in patients with TB.
