Alcohol use predicts elevation in inflammatory marker soluble CD14 in men living with HIV
2016
ABSTRACTIndependently, HIV infection and heavy alcohol use increase microbial translocation (MT) of gut products into systemic circulation. MT and consequent immune response have been linked to chronic inflammation and a host of negative health outcomes in individuals living with HIV. However, previous research has not systematically investigated the immune correlates of heavy drinking specifically within the HIV-positive population. This pilot study investigated MT and immune activation as a function of alcohol use in 21 HIV-positive men who met NIAAA criteria for heavy drinking. Participants averaged 46.7 ± 8.5 (mean ± standard deviation) years of age, 12.2 ± 9.2 years since HIV diagnosis, 337 ± 158 CD4 nadir, and 643 ± 245 current CD4 count. All participants were virologically suppressed on antiretroviral therapy. Data on alcohol use and immune function were collected at baseline and three-month follow-up. Plasma concentrations of markers of MT and immune activation (lipopolysaccharide (LPS), soluble C...
