Hepatic steatosis in individuals living with HIV measured by controlled attenuation parameter: a cross-sectional study
OBJECTIVESAvailable data on the prevalence of hepatic steatosis in an unselected HIV-infected population are limited. The aim of this study was to determine the prevalence of hepatic steatosis and assess the associated factors in HIV-infected individuals. PATIENTS AND METHODSOne hundred and thirty-six HIV-infected individuals were enrolled in this cross-sectional study. Patients underwent transient elastography and controlled attenuation parameter (CAP) measurements. We analyzed the associations between the CAP value and demographic, metabolic, and immunologic parameters. For the first time, in HIV-infected individuals, we used a continuous scale of CAP values to identify significant covariates of hepatic fat accumulation. As a result and compared with other methods, one of the main advantages of CAP was that the quantitative measurement of liver steatosis could be used for analysis. RESULTSUsing univariate analysis, CAP was significantly correlated with the following continuous variablesCD4 percentage (P=0.035), CD8 percentage (P=0.016), age (P<0.001), CD4/8 ratio (P=0.002), BMI (P<0.001), serum triglyceride (P<0.001), and serum cholesterol (P=0.004) levels, the length of known HIV positivity (P<0.001), and liver stiffness (P=0.041). With respect to categorical variables, a significant association was found for the presence of diabetes (P=0.006), hypertension (P<0.001), facial lipodystrophy (P=0.031), and the use of lopinavir (P=0.042). In multivariate analysis using linear regression, BMI (P<0.001), presence of diabetes (P=0.026), and hypertension (P=0.040) were identified as independent significant correlates. Darunavir therapy was associated negatively with the CAP value (P=0.032). CONCLUSIONOur findings reflect the importance of metabolic factors in hepatic steatosis. The strongest independent covariate was BMI..
