To describe the prevalence and factors associated with nonalcoholic fatty liver disease (NAFLD) among HIV-infected persons not infected with hepatitis C virus (HCV). A cross-sectional study among HIV-infected patients in a large HIV clinic. NAFLD was defined as steatosis among patients without viral hepatitis (B or C) co-infection or excessive alcohol use. The prevalence of NAFLD was identified by ultrasound examination evaluated by two radiologists blinded to the clinic information; liver biopsies were performed on a subset of the study population. Factors associated with NAFLD evaluated by proportional odds logistic regression models. Sixty-seven (31%) of 216 patients had NAFLD based on ultrasound evaluation. Among those with NAFLD, steatosis was graded as mild in 60%, moderate in 28%, and severe/ marked in 12%. Factors associated with the degree of steatosis on ultrasound examination in the multivariate model included increased waist circumference (odds ratio [OR] 2.1 per 10 cm, p<0.001), elevated triglycerides (OR= 1.2 per 100 mg/dl, p=0.03), and lower HDL levels (OR 0.7, p=0.03). African Americans were less likely to have NAFLD compared to Caucasians (14% vs. 35%), although this did not reach statistical significance (OR= 0.4, p=0.08). Similar associations were noted for the subset of patients diagnosed by liver biopsy. CD4 cell count, HIV viral load, duration of HIV infection, and antiretroviral medications were not independent risk factors associated with NAFLD after adjustment for dyslipidemia or waist circumference. NAFLD was common among this cohort of HIV-infected, HCV-seronegative patients. NAFLD was associated with a greater waist circumference, low HDL and high triglyceride levels. Antiretroviral medications were not associated with NAFLD; prospective studies are needed to confirm this finding.
