Given this concern, it is crucial to assess aging biomarkers and their correlation with the HIV reservoir in order to comprehensively characterize and monitor these individuals. Fifty-five PHIVAYA (median age: 23, interquartile range [IQR]: 20\u201327 years, and 21 [18\u201323] years on ART at the time of study sampling) were studied along with 23 age-matched healthy controls. The PHIVAYA exhibited significantly higher percentages of activated, senescent, exhausted CD4 and CD8 T cells, shorter telomeres, reduced thymic output, and higher levels of circulating inflammatory markers (PAMPs, DAMPs, and pro-inflammatory cytokines IL-6, IL-8, and TNF\u03b1) as well as denervation biomarkers (neural cell adhesion molecule 1 [NCAM1] and C-terminal Agrin fragment [CAF]), compared to controls. HIV-DNA levels positively correlated with activated, senescent, exhausted CD4 and CD8 T cells, circulating biomarkers levels, and inversely with regulatory T and B cells and telomere length. According to their viremia over time, PHIVAYA were subgrouped into 14 Not Suppressed (NS)-PHIVAYA and 41 Suppressed (S)-PHIVAYA, of whom 6 who initiated ART within one year of age and maintained sustained viral suppression overtime were defined as Early Suppressed (ES)-PHIVAYA and the other 35 as Late Suppressed (LS)-PHIVAYA. ES-PHIVAYA exhibited significantly lower HIV-DNA reservoir, decreased percentages of senescent and exhausted CD4 and CD8 T cells, reduced levels of circulating inflammatory and denervation biomarkers, but longer telomere compared to LS- and NS-PHIVAYA. They differed significantly from healthy controls only in a few markers, including higher percentages of regulatory T and B cells, and higher levels of DAMPs. Overall, these results underscore the importance of initiating ART early and maintaining viral suppression to limit the establishment of the viral reservoir and to counteract immune and cellular premature aging. These findings also suggest new approaches for minimally invasive monitoring of individuals at high risk of developing premature aging and age-related illnesses.<\/jats:p>","DOI":"10.1371\/journal.ppat.1012547","type":"journal-article","created":{"date-parts":[[2024,9,23]],"date-time":"2024-09-23T17:33:32Z","timestamp":1727112812000},"page":"e1012547","update-policy":"https:\/\/doi.org\/10.1371\/journal.ppat.corrections_policy","source":"Crossref","is-referenced-by-count":13,"title":["HIV
