Prevalence and Risk Factors of Moderate-to-Severe Hepatic Steatosis in Human Immunodeficiency Virus Infection: The Copenhagen Co-morbidity Liver Study

Abstract

Abstract Background People with human immunodeficiency virus (PWH) may be at risk of nonalcoholic fatty liver disease. We compared the prevalence of moderate-to-severe hepatic steatosis (M-HS) in PWH with human immunodeficiency virus (HIV)-uninfected controls and determined risk factors for M-HS in PWH. Methods The Copenhagen Co-Morbidity in HIV Infection study included 453 participants, and the Copenhagen General Population Study included 765 participants. None had prior or current viral hepatitis or excessive alcohol intake. Moderate-to-severe hepatic steatosis was assessed by unenhanced computed tomography liver scan defined by liver attenuation ≤48 Hounsfield units. Adjusted odds ratios (aORs) were computed by adjusted logistic regression. Results The prevalence of M-HS was lower in PWH compared with uninfected controls (8.6% vs 14.2%, P < .01). In multivariable analyses, HIV (aOR, 0.44; P < .01), female sex (aOR, 0.08; P = .03), physical activity level (aOR, 0.09; very active vs inactive; P < .01), and alcohol (aOR, 0.89 per unit/week; P = .02) were protective factors, whereas body mass index (BMI) (aOR, 1.58 per 1 kg/m2; P < .01), alanine transaminase (ALT) (aOR, 1.76 per 10 U/L; P < .01), and exposure to integrase inhibitors (aOR, 1.28 per year; P = .02) were associated with higher odds of M-HS. Conclusions Moderate-to-severe hepatic steatosis is less common in PWH compared with demographically comparable uninfected controls. Besides BMI and ALT, integrase inhibitor exposure was associated with higher prevalence of steatosis in PWH.
