HIV Treatment Reduces Accelerated Biological Aging by Nearly Four Years, Landmark Study Shows
A landmark study presented at ESCMID Global 2026 shows that antiretroviral therapy (ART) reduces the accelerated biological aging seen in people with HIV (PWH) by an average of 3.7 years after roughly 1.5 years of treatment. Researchers used a plasma proteomic aging clock (PAC) built from hundreds of blood‑protein markers to compare pre‑ART and post‑ART samples from the Swiss HIV Cohort Study. Untreated HIV infection was associated with a median ten‑year age acceleration, while sustained viral suppression gradually restored proteomic age toward chronological levels. The findings highlight inflammation‑driven aging as a reversible component of HIV disease.
