HIV-1 Infection Alters the Viral Composition of Plasma in Men Who Have Sex with Men.

ABSTRACT: Altered gut virome and expanded abundance of certain viruses were found in HIV-1-infected individuals. It remains largely unknown how plasma virus composition changes during HIV-1 infection and antiretroviral therapy (ART). We performed viral metagenomic analysis on viral particles enriched from human plasma from 101 men who have sex with men (MSM) with or without HIV-1 infection and whether or not on ART and compared the differences in the plasma virome. An increased plasma viral abundance of main eukaryotic viruses was observed during HIV-1 infection in MSM, especially in AIDS patients (CD4⁺ T cell counts of <200). Anellovirus, pegivirus and hepatitis B virus (HBV) were the most abundant blood-borne viruses detected among MSM and HIV-1-infected individuals, and anellovirus and
