Objective: To describe the clinical characteristics of drug-induced liver injury (DILI) in multidrug-resistant tuberculosis (MDR-TB) patients.Materials and methods: A retrospective study conducted in hospitalized patients with MDR-TB and DILI. The criteria of the DILI Expert Working Group were used for the diagnosis of DILI, and the RUCAM (Roussel Uclaf Causality AssessmentMethod) for the causality analysis. The specific association between DILI and antitubercular drugs was established by drug rechallenge or discontinuation and recovery. Results: Seven cases of MDR-TB and DILI are described in this research. The mean age (standard deviation) was 39.10 (3.30) years.Mean DILI occurred 30.40 (27.70) days after starting the treatment. Three (43.00 %) patients presented jaundice. Regarding the type of injury, four (57.00 %) had hepatocellular injury and three (43.00 %) cholestatic injury. Fou...
