Abstract
Background. The prevalence and predictors of nonalcoholic fatty liver disease (NAFLD) in human immunodeficiency virus (HIV)-infected highly active antiretroviral therapy-experienced patients and the association of NAFLD with risk of cardiovascular disease and subclinical atherosclerosis are unknown.
Methods. We performed a cross-sectional observational study. NAFLD was defined by liver-spleen attenuation values of <1.1 on computed tomography in persons who had neither evidence of chronic viral hepatitis nor a significant history of alcohol consumption.
Results. We enrolled 225 patients; 163 (72.4%) were men. Mean (±SD) HIV infection duration was 147 ± months, and mean (60 ± SD) body mass index (calculated as weight in kilograms divided by the square of height in meters) was 23.75 ± 3.59. NAFLD was diagnosed in 83 patients (36.9% of the total cohort). The following variables were significantly associated with NAFLD in univariate analyses: sex, waist circumference, body mass index, cumulative exposure to nucleoside reverse-transcriptase inhibitors, visceral adipose tissue, homeostasismodel assessment of insulin resistance index, serum alanine and aspartate aminotransferase levels, and ratios of total serum cholesterol to high-density lipoprotein cholesterol. Coronary artery calcium scores and a diagnosis of diabetes were not associated with NAFLD. In multivariable logistic regression analyses, factors associated (P < .001) with NAFLD were higher serum alanine to aspartate ratio (odds ratio, 4.59; 95% confidence interval, 2.09–10.08), male sex (odds ratio, 2.49; 95% confidence interval, 1.07–5.81), greater waist circumference (odds ratio, 1.07; 95% confidence interval, 1.03–1.11), and longer nucleoside reverse-transcriptase inhibitor exposure (odds ratio, 1.12 per year of exposure; 95% confidence interval, 1.03–1.22).
Conclusions. NAFLD is common among HIV-infected persons who have the traditional risk factors for NAFLD (elevations in serum alanine level, male sex, and increased waist circumference) apparent. Exposure to nucleoside reverse-transcriptase inhibitors was an independent risk factor for NAFLD, with an 11% increase in the odds ratio for each year of use.
