Chronic liver disease is an important cause of morbidity and mortality among people living with human immunodefciency virus (HIV) and is frequently related to non-alcoholic fatty liver disease (NAFLD). The objective is to estimate the prevalence and risk factors of hepatic steatosis among consecutive patients with stable HIV infection on antiretroviral therapy (ART). Also, the use of transient elastography (TE) as a mean to identify a subgroup at risk for non-alcoholic steatohepatitis (NASH) and/or liver fbrosis. HIV infected patients were enrolled between August2016 and February2017. Inclusion criteria: ≥18 years with undetectable HIV viral load. Exclusion criteria: pregnancy; alcohol intake ≥20g/day and co-infection B or C viruses. Patients underwent ultrasound (US) to diagnose liver steatosis. Signifcant fbrosis (≥F2) was estimated if at least one of the following were present: APRI>1.0, FIB4>3 and/ or liver stifness ≥7.1kPa. Subjects with TE≥7.1kPa were proposed a liver biopsy and NAFLD Scoring System (NAS)≥3 was considered as diagnosis of NASH. A total of 98 patients were included. Liver steatosis was diagnosed in 31 patients (31.6%) and was independently associated with male gender, BMI, ALT and total bilirubin levels. The prevalence of signifcant fbrosis assessed by TE, APRI and FIB4 was 26.9%, 6.4% and 3.2%, respectively. Seven patients had a TE result ≥7.1kPa. NASH was found in 5 (83.3%). Among HIV infected patients undergoing ART, almost one third have NAFLD. Neither TE, APRI or FIB4 were able to act as surrogates for signifcant liver fbrosis. Nevertheless, TE≥7.1kPa was able to accurately select a subgroup of patients at risk for NASH.
