Abstract

Drug-induced liver injury (DILI) is one of the most common adverse reactions of anti-tuberculosis treatment. To improve the diagnosis and management of anti-tuberculosis drug-induced liver injury (ATB-DILI) for clinicians and tuberculosis control workers, the Chinese Medical Association Tuberculosis Branch has developed guidelines for the diagnosis and treatment of ATB-DILI. These guidelines summarized recent research progress in relevant fields and provide detailed explanations, recommendations, and quality assessments related to ATB-DILI, covering aspects such as definition, risk factors, mechanisms, pathological manifestations, clinical classification, diagnosis, and management. The key recommendations are as follows.Recommendation 1: Risk factors: NAT2 slow acetylation genotype, GSTM1 gene variation, advanced age, hepatitis virus infection or concurrent acute/chronic liver disease, HIV infection, malnutrition, and alcohol (ethanol) intake are risk factors for ATB-DILI (2, B).Recommendation 2: R-value calculation: Calculate the R-value for suspected ATB-DILI patients at different time points during the course of the disease. ALT and ALP values should be obtained on the same day, with a maximum interval of no more than 48 hours. This helps to accurately determine the clinical type and prognosis of DILI (2, C).Recommendation 3: Comprehensive medical history collection: Collect information on past medication history, clinical features, dynamic changes in liver biochemical…
