Abstract

BACKGROUND The aim of this study was to investigate the clinical characteristics and the risk factors associated with anti-tuberculosis (anti-TB) drug-induced liver injury (DILI). MATERIAL AND METHODS This retrospective study enrolled 140 hospitalized patients diagnosed with anti-TB DILI during January 2009 to December 2015. We assessed the baseline characteristics and performed regular follow-up up to the 24th week to assess the possible risk factors associated with the condition. RESULTS The study population was 58.6% male and 41.4% female patients; 20.7% were diagnosed with grades 4-5 DILI and 79.3% with grades 1-3 DILI. Female patients were significantly more likely to be diagnosed with grades 4-5 DILI than with grades 1-3 DILI (58.6% vs. 36.9%, p=0.036). Patients treated with a multidrug anti-TB regimen were more commonly affected with grades 4-5 DILI (86.2% vs. 68.5%, p=0.045). A significant number of patients who reinitiated anti-TB therapy suffered severe liver injury in comparison to patients with grades 1-3 DILI (41.4% vs. 10.8%, P<.001). Laboratory examinations revealed significantly higher values for total bilirubin (TBL), International normalized ratio (INR), and Hy's law (P<.001) in the grades 4-5 group compare to...Continue Reading
