Background Liver injury is one of the most important adverse effects of antiretroviral therapy, leading to therapy changing or discontinuation. Data on liver injury in human immunodeficiency virus-1-infected patients receiving antiretroviral therapy are limited in China. The purpose of this study was to investigate the features of liver injury in human immunodeficiency virus type 1-infected patients receiving non-nucleosides reverse transcriptase inhibitors-based antiretroviral therapy in China.Methods Seventy-five patients on antiretroviral therapy containing non-nucleosides reverse transcriptase inhibitors were retrospectively studied. The patients were divided into 2 groups: group 1 (with liver injury, n=45) and group 2(without liver injury, n=30). The features of liver injury were analyzed. The sex, age, baseline CD4 counts, hepatitis B virus (HBV) and/or hepatitis C virus (HCV) co-infection, hepatotoxic drug use and nevirapine or efavirenz use were compared between two groups.Results Forty-five patients (60.0%), 31 (68.9%) males and 14 (31.1%) females, aged 12 to 52 years (averaged (3g±9)years), experienced at least one episode of liver injury. Forty (53.3%) patients were co-infected with HBV and/or HCV, 42 (56%) patients had concomitant use of antituberculosis drugs or cotrimoxazole, 46 (61.3%) and 29 (38.7%) patients received regimen containing nevirapine and efavirenz, respectively. Grade 1 liver injuries were observed in 26 (57.8%)patients, grade 2 in 16 (35.6%), grade 3 in 2 (4.0%) and grade 4 in 1 (2.2%). Three (6.7%) patients discontinued highly active antiretroviral therapy (HAART) due to liver injury. In group 1, there were 29 (64.4%) patients co-infected with HBV and/or HCV, 32 (71.1%) patients received regimen containing nevirapine, and 30 (66.7%) patients had concomitant use of anti-tuberculosis drugs or cotrimoxazole, respectively, significantly higher than those in group 2 (11 (36.7%), 14 (46.7%)and 12 (40%), respectively; P=0.018, 0.033, 0.023, respectively). The sex, age, baseline CD4 counts and disease stage were not factors associated with liver injury.Conclusions Liver injury associated with HAART containing non-nucleosides reverse transcriptase inhibitors was mild to moderate and those who were co-infected with HBV and/or HCV, had concomitant use of antituberculosis drugs or cotrimoxazole and received a regimen containing nevirapine were prone to liver injury while receiving HAART.
