Circulating levels of MCP-1, VEGF-A, sICAM-1, sVCAM-1, sE-selectin and sVE-cadherin: Relationship with components of metabolic syndrome in young population

Abstract

IntroductionInflammation and endothelial dysfunction are considered the primary manifestations of the cardiovascular disease. Studies have established a relationship among components of metabolic syndrome (MetS) with inflammatory markers and the loss of permeability, vasoconstriction and vasodilatation endothelial. ObjectiveTo determine the relationship among the concentrations of soluble endothelial dysfunction molecules and inflammation cytokines and components of the metabolic syndrome in young population. Material and methodsA study was performed in 240 young adult students ages 18–28 years. To define the presence of clinical and metabolic alterations and MetS the modified ATP-III criteria was considered. In all subjects were determined sociodemographic characteristics, anthropometric measures and the metabolic profile. Circulating levels of MCP-1, VEGF-A, sICAM-1, sVCAM-1, sE-selectin and sVE-cadherin were determined by ELISA immunoassay (Bioscience). Statistical analysis was performed using STATA statistical software v. 9.2. ResultsFrom all the participants, 44.6% had obesity, 59.9% had abdominal obesity, 49.6% low HDL-c and 16.7% high levels triglycerids. The 16.25% of the population showed 3 or more components of the MetS. Elevated MCP-1, sICAM-1 and sE-selectin levels were linked to the presence of obesity. In a model adjusted by age–gender, high soluble levels of MCP-1 and VEGF-A were linked with abdominal obesity (OR=1.83; 1.02–3.28 and OR=2.03; 1.15–3.56, respectively), as well as to the presence of the 2 components of MetS. sVCAM-1 levels were associated with impaired glucose (OR=4.74; 1.32–17.0); sE-selectin with low HDL-c (OR=1.99; 1.05–3.75), although sICAM-1 and sVE-cadherin were associated with impaired systolic blood pressure (OR=4.04; 1.24–13.1 and OR=6.28; 1.90–20.7, respectively). ConclusionLevels of circulating MCP-1 and VEGF-A were associated with adiposity, levels of sVCAM-1 with the presence of impaired glucose, sE-selectin with low HDL-c, while the levels of sICAM-1 and sVE-cadherin were associated with impaired systolic blood pressure in young adults independently of other traditional risk factors.
