Gut Integrity, Microbial Translocation, Immune Activation, Inflammation And Vitamin D In Drug Users Living With Hiv, Jacqueline S. Hernandez Mar 2020

Gut Integrity, Microbial Translocation, Immune Activation, Inflammation And Vitamin D In Drug Users Living With Hiv, Jacqueline S. Hernandez

FIU Electronic Theses and Dissertations

The purpose of this study was to examine associations between MT, immune activation, inflammation, gut integrity and vitamin D status in the context of cocaine use among People Living with HIV (PLWH). One hundred cocaine and non-cocaine users living with HIV were selected from the Miami Adult Studies in HIV cohort. Blood samples were collected to assess MT (LPS), immune activation (sCD163 and sCD27), inflammation (IL-6, TNF-a, hs-CRP, IL-17 and IL-22), gut integrity damage (I-FABP) and vitamin D status. Data on socio-demographic characteristics, anthropometrics, diet and disease progression were collected. Descriptive statistics, independent t-test, multiple linear and logistic regressions were …

Cocaine and other drugs of abuse increase HIV-induced immunopathogenesis; and neurobiological mechanisms of cocaine addiction implicate a key role for microRNAs (miRNAs), single-stranded non-coding RNAs that regulate gene expression and defend against viruses. In fact, HIV defends against miRNAs by actively suppressing the expression of polycistronic miRNA cluster miRNA-17/92, which encodes miRNAs including miR-20a. IFN-g production by natural killer cells is regulated by miR-155 and this miRNA is also critical to dendritic cell (DC) maturation. However, the impact of cocaine on miR-155 expression and subsequent HIV replication is unknown. We examined the impact of cocaine on two miRNAs, miR-20a and …
