There has been an increase the prevalence of andrological diseases in all age groups in recent decades, including those with comorbid conditions such as pathology of the cardiovascular system and liver, which are manifestations of metabolic syndrome.Research aim: to investigate the relationship between formation of hepatic steatosis and hypoandrogenism (HA) in adolescent boys.Materials and methods. The study involved 42 adolescent boys aged 14–18 years with laboratory confirmed HA in whom total testosterone levels were less than 12.0 nmol/l. Sex hormones, gonadotropins, insulin levels, biochemical parameters of liver function, the state of free radical oxidation and antioxidant protection were determined in patients. Based on ultrasound examination adolescents with HA were divided into 2 groups: group 1 – 15 adolescents with signs of liver steatosis; group 2 – 27 adolescents with normal ultrasound parameters of a liver. The control group consisted of 38 boys of the same age with normal indicators of physical and sexual development without signs of pathology of the hepatobiliary system. Results. Individual assessment of sexual development allowed to diagnose I degree of delayed sexual development in 44.7%, II degree in 38.3% and III degree in 17.0% of adolescents. HA negatively affects the physical development of most boys (78.7%), due to short stature (40.0%), weight deficiency (20.0%) and overweight (18.7%). Factor analysis allowed to build a factor model of hepatic steatosis formation in adolescents with delayed sexual development and HA, which describes 76.0% of the sample and consists of five factors. Conclusion. Atherogenic changes of the lipid profile, androgen deficiency, insulin resistance, activation of cytolytic processes in the liver and oxidative stress formation due to a decrease in the effectiveness of antioxidant protection are important in the pathogenesis of hepatic steatosis in boys with HA. A factor model of the hepatic steatosis development in adolescent boys with HA gives grounds for the development of therapeutic and preventive measures in adolescent boys with HA and comorbid liver pathology.
Abstract. Background. The purpose of the study is to evaluate the efficacy of hepatoprotectors in comprehensive treatment of adolescents with obesity, non-alcoholic fatty liver disease and dysfunctional disorders of the biliary tract (DDBT
Background. The purpose was to determine the structure and age characteristics of clinical and endoscopic features of gastroduodenal pathology in adolescence. Materials and methods. The study included 493 adolescents between 10 and 14 years of age and 444 adolescents aged 15 to 18 years. Clinical, laboratory and instrumental studies were conducted (esophagogastroduodenoscopy, intragastric pH-metry, Helicobacter pylori DNA). Results. The study showed that in adolescence, the inflammatory lesions of the upper digestive tract predominate in both age groups. Destructive lesions occur in 8-10 % of patients in the 10-14 age group, and their incidence increases 2 times in boys and 1.5 times-in girls in the 15-18 age group. Motility disorders of the upper digestive tract are determined in 30 % of patients regardless of age, more often in girls. Lesions of the upper digestive tract are usually accompanied by basal gastric hyperacidity in boys, while in girls the basal normacidity is more often determined. Helicobacter pylori infection is detected in 2/3 of adolescents with disorders of the upper digestive tract, slightly more often in the 10-14 age group. Conclusions. The results obtained in the course of the study can focus the directions of etiotropic and pathogenetic therapy for the upper digestive tract diseases depending on the age and gender of the patients.
Recently, interest in the problem of free radical oxidation in biological membranes, which is directly related to both the normal functioning of cells and the occurrence, course and outcome of many pathological conditions, has increased again in clinical medicine. The aim was to determine the role and impact of antioxidant defense in boys with hypoandrogenism. The study involved 75 adolescents with hypoandrogenism aged 13–18 years, who underwent a complex of clinical and laboratory examinations. All patients were conducted complex of anthropometric research and determination of the degree of delayed puberty, laboratory and instrumental examination. Free radical oxidation was determined by the levels of malondialdehyde, conjugated dienes, carbonated proteins, superoxide dismutase and catalase in the serum, and restored glutathione and glutathione peroxidase in whole blood. Based on their determination, the coefficient of oxidative stress was calculated. Statistical processing of results was performed using parametric and nonparametric methods. The study of indicators of the free radical oxidation process found that adolescents with hypoandrogenism have multidirectional changes in the oxidation of proteins and lipids, namely: the level of conjugated dienes increases, the concentration of malondialdehyde remains at the level of the control group, and the level of carbonated proteins tends to decrease. As for the activity of antioxidant protection enzymes, a significant decrease in the level of glutathione peroxidase was detected, while the level of superoxide dismutase and catalase remained at the level of normative indicators. Oxidative stress accompanies and is one of the pathogenetic links in the formation or maintenance of the state of hypoandrogenism in boys. This requires the use of antioxidants, the complex of which must be selected individually.
