Liver disease is now a leading cause of non-AIDS related morbidity and mortality in people living with HIV (PLWH). The present study investigated the interplay between adverse lifestyle factors that are prevalent in PLWH, biological mediators of liver pathogenesis, and a non-invasive measure of liver fibrosis (FIB-4 index) in HIV mono- and HIV/HCV co-infected individuals.
The results of this investigation in the Miami Adult Studies of HIV (MASH) cohort show that the odds of liver fibrosis progression significantly increased over two years for HIV mono-infected participants who drank alcohol hazardously (OR 3.038, P=0.048), and had BMI ≥ 28kg/m2 …

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 …
