Abstract: PURPOSE: Elevated levels of inflammation associated with human immunodeficiency virus (HIV) infection are one of the primary causes for the burden of age-related diseases among people with HIV (PWH). Circulating proteins can be used to investigate pathways to inflammation among PWH. EXPERIMENTAL DESIGN: cell count among 87 black South African PWH before antiretroviral therapy (ART). RESULTS: cell count, and age respectively. Twelve out of 14 age-associated proteins have been reported to be associated with age in the general population, and 4 have previously shown significant associations with age for PWH. Furthermore, many of the age-associated proteins such as CST5, CCL23, SLAMF1, MMP-1, MCP-1, and CDCP1 have been linked to chronic diseases such as cardiovascular disease and neurocognitive decline in the general population. We also found a synergistic interaction between male and older age accounting for excessive expression of CST5. CONCLUSIONS AND CLINICAL RELEVANCE: We found that advanced age may lead to the elevation of multiple inflammatory proteins among PWH. We also demonstrated the potential utility of proteomics for evaluating and characterizing the inflammatory status of PWH.
