Abstract

Introduction. The interest in the study of anti-oxidized low-density lipoproteins (anti-oxLDL) is due to their association with the development and progression of atherosclerosis and metabolic syndrome. Purpose of the study. To study the level of antibodies of oxidized low-density lipoproteins (anti-oxLDL) in serum in obese children. Materials and Methods. 76 children aged 5 to 17 years participated in the study. A standard objective and laboratory examination was performed, including physical and sexual development, lipidogram and anti-oxLDL levels. To assess anthropometric data, the standard deviation coefficient was calculated using the Auxology application. The parameters of fat metabolism were determined according to the data of blood biochemical analysis. The content of anti-oxLDL was determined by immuno-enzymatic analysis using test kits “Biomedica”. Results. According to the results of the examination the patients were divided into three groups: group 1 included 36 children with constitutional-exogenous obesity and increased level of anti-oxLDL, group 2-30 patients with constitutional-exogenous obesity and normal level of anti-oxLDL, group 3-10 healthy children. The level of antibodies to oxidized low density lipoproteins (oxLDL) in obese children is 11.6 times higher compared to healthy children. The antibody titer in prepubertal children is 2206 [1809;2603] IU/mL, and in adolescents it is 1505.5 [1109;1902] IU/mL. The highest values of anti-oxLDL levels were observed in patients with 1st degree obesity 2623 [2245;3001] IU/mL and 3rd degree obesity 2914.5 [2678;3151] IU/mL. Conclusion. High of anti-oxLDL levels were found in pre-pubertal children with obesity, especially in 1st and 3rd degree obesity. In obese children, the level of anti-oxLDL has a direct correlation with the duration of the underlying disease and the increase in low-density lipoprotein (LDL) levels. Further studies are needed on the role of anti-OCOLDL as an early predictor of atherosclerosis in clidren with obesity.
