[Redox status parameters in adolescent-mongoloids with exogenously constitutional obesity and fatty hepatosis]

It is assumed that in the progression of obesity, complicated by fatty hepatosis in adolescents, a significant role is given to the reactions of oxidative stress with deficiency of antioxidant factors. However, an important factor that remains outside the field of view of researchers is the ethnicity of the patient, which is an important element in the development of a personalized approach in the treatment and prevention of diseases. In connection with this, the purpose of this study was to study the changes in the lipid peroxidation-antioxidant defense processes in adolescent Mongoloids with exogenously constitutional obesity complicated by fatty hepatosis. 18 adolescent boys with fatty hepatosis were examined on the background of exogenous-constitutional obesity of the first degree; 38 adolescent boys with exogenously constitutional obesity without changes in the liver and 37 practically healthy adolescents (control group). All subjects surveyed for ethnicity belonged to the Mongoloids. Spectrophotometric and fluorometric methods were used in the research. The results of the study indicated a high intensity of lipid peroxidation reactions in Mongoloid boys with obesity and fatty hepatosis relative to control values: an increase in blood plasma content of compounds with unsaturated double bonds (p<0.001), diene conjugates (p=0.0012), ketodienes and conjugated trienes (p<0.0001), in the absence of significant differences in the level of TBA-active products. Increased values of total antioxidant activity in blood plasma (p=0.0023) and erythrocyte superoxide dismutase activity (p=0.0072), decreased levels of fat-soluble vitamins in blood plasma [α-tocopherol (p<0.0001) and retinol (p=0.0011)] and oxidized form of glutathione in erythrocytes (p=0.0083) have been found. The pronounced insufficiency of fatsoluble vitamins - α-tocopherol and retinol in patients of the main group was also noted in comparison with patients without morphological changes in the liver. Thus, in teenage Mongoloids with exogenously constitutional obesity and fatty hepatosis, it is possible to recommend antioxidant drugs in addition to basic metabolic therapy.
