Abstract: Background While a low CD4/CD8 ratio during HIV treatment correlates with immunosenescence, its value in identifying patients at an increased risk for clinical events remains unclear.Methods We analyzed data from the CoRIS cohort to determine whether CD4 count, CD8 count, and CD4/CD8 ratio at year two of antiretroviral therapy (ART) could predict the risk of serious non-AIDS events (SNAEs) during the next five years. These included major adverse cardiovascular events, non-AIDS-defining malignancies, and non-accidental deaths. We used pooled logistic regression with inverse probability weighting to estimate the survival curves and cumulative risk of clinical events.Findings The study included 4625 participants, 83% male, of whom 200 (4.3%) experienced an SNAE during the follow-up period. A CD4/CD8 ratio <0.3 predicted an increased risk of SNAEs during the next five years (OR 1.63, 95% CI 1.03-2.58). The effect was stronger at a CD4/CD8 ratio cut-off of <0.2 (OR 3.09, 95% CI 1.57-6.07). Additionally, low CD4 count at cut-offs of <500 cells/mu L predicted an increased risk of clinical events. Among participants with a CD4 count >500 cells/mu L, a CD8 count >1500 cells/mu L or a CD4/CD8 ratio <0.4 predicted increased SNAE risk.Interpretation Our results support the use of the CD4/CD8 ratio and CD8 count as predictors of clinical progression. Patients with CD4/CD8 ratio <0.3 or CD8 count >1500/mu L, regardless of their CD4 count, may benefit from closer monitoring and targeted preventive interventions.Copyright (c) 2023 The Author(s).
