Abstract
Drug-induced hepatotoxicity represents a major clinical challenge in the management of patients with Human Immunodeficiency Virus (HIV), tuberculosis (TB), and HIV–TB coinfection, largely due to prolonged and combined therapeutic regimens that increase exposure to potentially hepatotoxic drugs. Early detection and appropriate classification of liver injury remain essential to prevent severe complications and treatment interruptions. This narrative review aims to examine the integration of hepatotoxicity monitoring with pharmacogenetic determinants in the context of HIV and tuberculosis therapy. Current evidence on the epidemiology, pathophysiological mechanisms, diagnostic approaches, and pharmacogenetic predictors of hepatotoxicity is summarized, with particular emphasis on genetic polymorphisms in drug-metabolizing enzymes such as N-acetyltransferase 2 (NAT2) and cytochrome P450 2B6 (CYP2B6), which influence susceptibility to liver injury associated with isoniazid and efavirenz. The available literature indicates that systematic biochemical monitoring, combined with pharmacogenetic information, may improve risk stratification, facilitate early detection of hepatotoxicity, and support more individualized therapeutic strategies. Integrating clinical assessment with pharmacogenetic data could therefore contribute to optimizing treatment safety and advancing personalized medicine approaches in populations affected by HIV and tuberculosis.
