Background: As per the World Health Organization Global Tuberculosis (TB) Report 2019, there were an estimated 10.0 million new TB cases worldwide in 2018, with India (27%) having the maximum burden of the disease. Drug-induced liver injury (DILI) due to antitubercular treatment (ATT) is a serious adverse effect and a major cause of discontinuation of ATT, leading to increased drug resistance, morbidity, and mortality. Methodology: This was an observational study that was conducted at a tertiary care center in South Maharashtra having a dedicated TB nodal center. All newly detected cases of pulmonary and extrapulmonary TB and cases of TB after relapse/failure/treatment after default, who reported to this nodal center from January 2019 to June 2019 and in whom Category 1 and Category 2 ATT was started as per the Revised National Tuberculosis Programme protocol, were enrolled in this study. Results: Out of 100 enrolled patients, 10 (10%) were diagnosed to have ATT-induced DILI, which is concordant with other studies. No deaths were recorded. However, there was no statistically significant difference between male and female patients who developed DILI (12% males vs. 8% females). No correlation was found with body mass index or alcohol consumption. Conclusion: A fine balance should be struck between unnecessary discontinuation of ATT and continued safe treatment. Patient and staff education, careful selection of regimen, and close monitoring of risk factors will minimize cases of DILI.
