Objectives: The study aimed to investigate the incidence of and risk factors for liver damage in patients with human immunodeficiency virus type-1 (HIV-1) mono-infection receiving antiretroviral therapy (ART).
Methods: We retrospectively analyzed the clinical data of patients who were diagnosed with HIV-1 infection and initiated ART from January to December 2017. Among them, 382 patients with HIV-1 mono-infection and normal baseline liver function were included in the analysis. The incidence of liver damage at each follow-up point, and possible risk factors for liver damage were evaluated via COX regression survival analyses.
Results: The overall incidence of liver damage (grade I-IV) was 27.23% (interquartile range [IQR]: 26.38%-28.72%). Grade I liver damage was most common and accounted for 22.13% of cases (IQR: 21.06%-24.04%), while grade II liver damage accounted for 3.40% of cases (IQR: 3.19%-4.26%). COX regression and survival analyses revealed that baseline body mass index (BMI), alanine aminotransferase (ALT) level, CD4+ T cell count, HIV-1 viral load, and the antiretroviral regimen were significantly correlated with the occurrence of liver damage. Moreover, baseline ALT levels and HIV-1 viral load were identified as independent risk factors for liver damage in patients with HIV-1 mono-infection.
Conclusion: Liver damage is common in patients with HIV-1 mono-infection undergoing ART. Patients with risk factors for liver damage should be well-informed before the initiation of ART, and liver function should be closely monitored during ART even in patients with normal liver function before ART.
