High-throughput proteomic analysis reveals systemic dysregulation in virally suppressed people living with HIV.

ABSTRACT: BACKGROUNDPeople living with HIV (PLHIV) receiving antiretroviral therapy (ART) exhibit persistent immune dysregulation and microbial dysbiosis, leading to development of cardiovascular diseases (CVDs). We initially compared plasma proteomic profiles between 205 PLHIV and 120 healthy control participants (HCs) and validated the results in an independent cohort of 639 PLHIV and 99 HCs. Differentially expressed proteins (DEPs) were then associated to microbiome data. Finally, we assessed which proteins were linked with CVD development in PLHIV.METHODSProximity extension assay technology was used to measure 1,472 plasma proteins. Markers of systemic inflammation (C-reactive protein, D-dimer, IL-6, soluble CD14, and soluble CD163) and microbial translocation (IFABP) were measured by ELISA, and
