Abstract
Objective — to study the relationship between indicators of oxidative stress and lipid metabolism in adolescent boys with hypoandrogenism (HA). Materials and methods. A survey of 29 adolescents aged 13—18 years with HA was conducted. The comparison group consisted of 84 boys of similar age with normal sexual and physical development. The concentration of testosterone, indicators of free radical oxidation, antioxidant system and lipid metabolism were measured. The results were aggregated using the Wilcoxon—Mann—Whitney criteria, the Fisher angular transform, and the Pearson coefficient. Results and discussion. It has been established that the majority of adolescent boys with HA have type IIa dyslipidemia,which is recorded 2.5 times more oftenwith a high level of oxidative stress. Various interrelationships between pro and antioxidant systems with indices of blood lipid spectrum in adolescent boys with HAare revealed, the pattern depends on the degree of oxidative stress. In boys, with normal (physiological) value of the oxidative stress coefficient, multiple intersystem interactions were found indicating the main role of the antioxidant defense system in regulating lipid metabolism, which indicates a sufficiently high compensatory and adaptive capabilities of the body to maintain the functional state at the proper level. With an increase in the degree of oxidative stress, there are other relationships between the studied parameters with the connection of the mechanisms of the regulatory influence of testosterone and free radical oxidation. In boys, with normal (physiological) value of the oxidative stress coefficient, multiple intersystem interactions were found indicating the main role of the antioxidant defense system in regulating lipid metabolism, which indicates a sufficiently high compensatory and adaptive capabilities of the body to maintain the functional state at the proper level. With an increase in the degree of oxidative stress, other relationships between the studied parameters occur, withemergence of regulatory influence of testosterone and free radical oxidation. Conclusions. With an increase in the degree of oxidative stress, the detected correlation between the indicators of free radical oxidation, antioxidant system and lipid metabolism suggests the development of maladaptive processes and emerges as an unfavorable prognostic factor for an increased risk of atherosclerosis and cardiovascular diseases, which requires timely and effective correction of metabolic changes.
