Immunoaging at Early Ages Could Drive a Higher Comorbidity Burden in People with HIV on Antiretroviral Therapy Compared with the Uninfected Population. | LitMetric
* It compared 40 PWH divided into two age groups (40-45 and ≥60 years) with 30 HIV-negative controls matched by sex and age.
* Results indicate that older PWH had more health issues and higher CD8 T cell counts, while younger PWH showed signs of accelerated immune aging and higher inflammatory markers, suggesting a need for early medical interventions.
Article Abstract
This is an observational, cross-sectional, comparative case-control, pilot study aimed at assessing the impact of HIV infection and age on immunological markers in people with HIV (PWH) on antiretroviral therapy (ART). The study included 40 PWH on ART, divided into two age groups (40-45 years vs. ≥60 years), and 30 HIV-uninfected controls matched by sex and age. The results show that older PWH on ART had more comorbidities and a higher frequency of CD8 T cells compared to older controls, with a significant decrease in CD8 naïve T cells with age. Additionally, younger PWH on ART exhibited higher frequencies of activated CD8 T cells and elevated levels of inflammatory markers (sCD14, IL-6) compared to age-matched controls, with values similar to those of older PWH on ART. These findings suggest that younger PWH on ART may experience accelerated immunoaging, highlighting the need for early interventions in this population.
