Dynamics of indicators of endothelial dysfunction in children with obesity

Introduction. Constitutionally exogenous obesity (CEO) belongs to a number of significant medical and social problems of the modern world, assumes epidemic proportions and leads among alimentary-dependent pathology in children. The aim of the work was to determine changes in indicators of endothelial dysfunction (ED) in children of different age with obesity of various severity. Materials and methods. One hundred twenty six children aged of 6 to 17 years were comprehensively examined, data on changes in the serum content of ED mediators in CEOs grade 1-3 were presented by quantitative determination of nitric oxide, endothelin-1, leptin, homocysteine, intercellular adhesion molecules and vascular cell adhesion-1, tissue-type plasminogen activator inhibitor antigen, Willebrand factor and his antigen. Results. The regularities of changes in the concentrations of these compounds in the blood depending on the age of patients and the degree of obesity, which reflect the functional state of the endothelial system and can serve as criteria for the severity of ED requiring adequate and timely correction in children, have been established. Conclusion. Indicators of endothelial dysfunction can serve as criteria for its severity, their detection will allow optimizing early diagnosis and determining the amount of timely therapy.
