ABSTRACT
BackgroundMetabolic syndrome (MetS), a cluster of factors associated with risks developing cardiovascular diseases, is public health concern because its growing prevalence. Considering the combination concomitant components, their development and severity, MetS phenotypes are largely heterogeneous, inducing disparity in diagnosis.MethodsA case/control study was designed within NuAge longitudinal cohort on aging. From 3-year follow-up 123 stable individuals, we present deep phenotyping approach based multiplatform metabolomics lipidomics untargeted strategy to better characterize metabolic perturbations define comprehensive signature over time older men.FindingsWe significant changes MetS, involving modulations 476 metabolites lipids, representing 16% detected serum metabolome/lipidome. These results revealed systemic alteration metabolism, various pathways (urea cycle, amino-acid, sphingo- glycerophospholipid, sugar metabolisms…) not only intrinsically interrelated, but also reflecting environmental (nutrition, microbiota, physical activity…).InterpretationThese findings allowed identifying signature, reduced 26 for future translation into clinical applications diagnosing MetS.FundingThe Study supported by research grant from Canadian Institutes Health Research (CIHR; MOP-62842).
