Abstract

Abstract : Objectives: To assess the association among immune activation, immune senescence, inflammation biomarkers and renal function measured by estimated glomerular filtration rate (eGFR) at inclusion and its evolution over a 3-year follow-up in HIV-infected patients with undetectable viral load. Design: The Chronic Immune Activation and Senescence (CIADIS) substudy consecutively included patients between October 2011 and May 2013 enrolled in the ANRS CO3 Aquitaine observational cohort. Methods: Biomarkers of T-cell activation, differentiation and senescence were summarized in a cellular-CIADIS weighted score and inflammation biomarkers in a soluble-CIADIS weighted score using principal component analysis. Logistic regression and linear mixed models were used to determine the association between the CIADIS weighted scores and confirmed eGFR less than 60 ml/min per 1.73 m 2, and evolution of eGFR, respectively. Results: Of 756 patients with an undetectable viral load, 76% were men, and median age was 51 years (Interquartile range: 45–57 years). In multivariable analysis, the soluble-CIADIS weighted score was independently associated with a confirmed eGFR less than 60 [odds ratio = 1.4; 95% confidence interval (CI) 1.1–1.8] but the cellular-CIADIS weighted score was not (odds ratio = 1.2; 95% CI 1.0–1.5). Only in patients with a confirmed eGFR less than 60 ml/min per 1.73 m 2 at inclusion, a higher soluble-CIADIS weighted score (increased inflammation) was associated with a steeper decrease of renal function of −2.3 (ml/min per 1.73 m 2 ) per year (95% CI −3.6 to −1.0). Conclusion: At inclusion, soluble-CIADIS weighted score was independently associated with a confirmed eGFR less than 60 ml/min per 1.73 m 2 . The soluble-CIADIS weighted score was associated with a decrease of eGFR evolution during a 3-year follow-up only in patients with a confirmed eGFR less than 60 ml/min per 1.73 m 2 .
