Reactivity features of cytokines and vasculoendothelial growth factor in patients with chronic cerebral ischemia and metabolic syndrome

Abstract

The purpose of the research is to determine the correlation between cytokines (interleukin-6, interleukin-10), vasculoendothelial growth factor, biochemical and anthropometric parameters in patients with chronic cerebral ischemia and metabolic syndrome. We examined 77 patients with chronic cerebral ischemia divided into 2 groups: with metabolic syndrome and without metabolic syndrome. In addition to neuroimaging, anthropometric and biochemical research we determined serum concentrations of interleukin-6, interleukin-10 and vasculoendothelial growth factor. It was found that patients with chronic cerebral ischemia and metabolic syndrome had significantly higher concentrations of interleukin-6, vasculoendothelial growth factor, indicators of weight, body mass index, waist circumference, glucose concentration, triglycerides, very low density lipoproteins, and high density lipoproteins was lower compared with the group without metabolic syndrome. During the comparing process of the biomarkers concentrations depending on gender, it was found that in patients with chronic cerebral ischemia and metabolic syndrome, the concentration of interleukin-6 was significantly higher in women than in men. Examination of all patients with chronic cerebral ischemia showed a direct correlation between the concentrations of interleukin-6 and glucose, the concentrations of interleukin-6 and weight, the concentrations of interleukin-6 and the waist circumference and between the concentration of vasculoendothelial growth factor and the waist circumference, in the group with metabolic syndrome - between the concentrations of interleukin-6 and interleukin-10, and in the group without metabolic syndrome - between the waist circumference and the atherogenic coefficient, between the concentrations of low density lipoproteins and β-lipoproteids, between the concentrations of low density lipoproteins and very low density lipoproteins. Thereby, metabolic syndrome is an additional complicating factor that comprehensively affects the reactivity of cytokines and vasculoendothelial growth factor in the pathogenesis of chronic cerebral ischemia.
