Liver Damage During Treatment with Reverse-Transcriptase Inhibitors in HIV Patients

摘要

The advent of highly active antiretroviral therapy (HAART) in 1996 has markedly enhanced the life expectancy of people living with HIV (PLWH), largely due to the effectiveness of reverse transcriptase inhibitors (RTIs). These drugs target the reverse transcriptase enzyme, crucial for the HIV virus to convert its RNA into DNA within host cells, effectively disrupting the viral replication process. This action reduces the patient’s viral load, helping preserve immune function and prevent progression to AIDS. Consequently, the predominant causes of mortality among individuals living with HIV have transitioned from opportunistic infections and AIDS-related cancers to liver disease and cardiovascular complications. Liver damage in PLWH could arise from multiple sources including co-infections, chronic substance use, and notably, antiretroviral therapy itself, which can be hepatotoxic. This review highlights the risks of hepatic damage associated with nucleoside and non-nucleoside RTIs and underscores the variability in hepatotoxicity risks among different drugs. It emphasizes the necessity for regular monitoring of liver health in PLWH and adjusting antiretroviral regimens to minimize liver fibrosis risk. This risk is particularly pronounced in patients who associate the infection with hepatitis B or C virus, where the potential for hepatotoxicity significantly increases.
