Abstract. Against the background of the steady pace of urbanization, the negative impact of anthropogenic toxic substances on human health is increasing every year. The most sensitive to the action of ecotoxicants is the child and adolescent organism. Given the acute reaction of the skin to the influence of toxic chemicals, aggravated by humoral changes in the body during puberty, the identification of criteria for the toxic etiology of acne is certainly relevant. The aim of the study was to determine the criteria of the predominantly toxicological mechanism of acne formation. To assess the effect of anthropogenic dermatotoxicants on the formation of acne, 595 children and various districts of the Moscow region were examined, of which 301 adolescents suffered from acne, and 294 practically healthy children made up the control group. The study used spectrometric, cytogenetic, biochemical and immunological research methods. The content of essential and toxic trace elements in adolescent hair samples was evaluated. A micronuclear test was performed in buccal epithelial cells. The testosterone level and the immunoregulatory index were evaluated. The results obtained in the study indicate at least two mechanisms of the formation of acne vulgaris in adolescents. The first is associated with a violation of the regulation of sex hormones, and the second with the dermatotoxicity of anthropogenic ecotoxicants. Adolescents with predominantly intoxicating etiology were characterized by low concentrations of selenium and zinc, high mercury and lead in hair samples, as well as an increase in the number of micronuclei in the buccal epithelium. Adolescents with predominantly hormonal etiology were characterized by an increase in testosterone levels and a decrease in the immunoregulatory index. At the same time, in adolescents with signs of genetic instability determined by the results of a micronucleus test, the clinical course of acne was significantly more severe than in children without pronounced karyopathology. Based on statistical processing of these data, prognostic algorithms were built to differentiate acne in adolescents by etiological factor. Thus, anthropogenic chemical toxicants, represented mainly by heavy metal salts, have an aggravating effect on the formation and course of acne in adolescents.
Among skin diseases in children and adolescents, the most common pathology is acne. The main pathogenetic link of acne in adolescents is hormonal imbalance. The effect on the sebaceous glands of high concentrations of dihydrotestosterone causes a change not only in the quantitative but also in the qualitative composition of the sebaceous secretion. The study is devoted to assessing the characteristics of sexual development, immune status and biochemical parameters in boys suffering from acne. Materials and methods. Materials and methods. A comparative analysis of the state of immunity, sexual development, biochemical parameters of 147 boys suffering from acne, and 142 healthy boys who do not suffer from acne. It was found that the immune status of boys suffering from acne was characterized by a decrease in cytotoxic lymphocytes. In the peripheral blood of these boys, serum interferon , tumor necrosis factor , interleukins 1, 2, 8 and 10, as well as small circulating immune complexes were significantly higher than in the boys of the control group. In boys suffering from acne, in the puberty period, the concentration of prolactin in 1314 years is significantly lower, and testosterone levels are significantly higher than in boys of the control group of the same age. At 1517 years of age, the concentration of luteinizing hormone in boys with acne is significantly lower, and testosterone is higher than in boys in the control group. Evaluation of the degree of formation of secondary sexual characteristics indicates that boys suffering from acne differed from their peers from the control group by a small advance in sexual development. Thus, boys suffering from acne, characterized by advanced and disharmonious puberty.
The physiological characteristics of sexual development and immune status in girls suffering from acne disease have been analyzed. It is revealed that at puberty, in girls suffering from acne, the concentration of luteinizing and follicle-stimulating hormone in peripheral blood was significantly lower than girls in the control group. While menarche was in girls 14-13 years old with acne there indexes were significantly less than in the control group. The formation of breast and pubic hair at puberty, they lagged behind in comparison with girls in the control group. The immune status of acne was characterized by a decrease in cytotoxic lymphocytes and increased T-lymphocytes helper cells and immunoregulatory index. In the peripheral blood of these girls there was an increase in interleukin-4 and serum tumor necrosis factor, level of circulating immune complexes, mainly due to the low concentration of serum interferon γ was significantly lower than in healthy girls. The indicators of basal metabolism indicate that girls with acne disease higher rates of creatinine and glucose, and also lower neeterificirovannah fatty acids and enzyme activities of alanine (Alat) and aspartic (AST) transferases than girls in the control group. Thus, ladies suffering from acne, was characterized by delayed and at the same time disharmonious puberty. They are characterized by a later menarche, delayed the establishment of the rhythm of the menstrual cycle, some changes of rhythm humoral regulation and biochemical homeostasis.

Comparative analysis of immune status and pubertal development in healthy girls and those suffering from acne disease. It is revealed that the immune status of girls suffering from acne disease, characterized by a decrease in cytotoxic lymphocytes, increase T-lymphocytes helper cells and immunoregulatory index. In the peripheral blood of these girls there was an increase in interleukin-4 and serum tumor necrosis factor, level of circulating immune complexes, mainly due to the low was significantly lower than in g concentration of serum interferon healthy girls. In girls suffering from acne in puberty the concentration of luteinizing and follicle-stimulating hormone in peripheral blood was significantly lower than girls in the control group. While menarche in girls 14-13 years old, with acne, there were significantly less than in the control group. The formation of breast and pubic hair at puberty, they lagged behind in comparison with girls in the control group. The indicators of basal metabolism indicate that girls with acne disease higher rates of creatinine and glucose, and also lower essential fatty acids and enzyme activities of alanine and aspartic transferases than girls in the control group. Thus, ladies suffering from acne, was characterized by delayed and at the same time disharmonious puberty. They are characterized by a later menarche, delayed the establishment of the rhythm of the menstrual cycle, some changes of rhythm humoral regulation and biochemical homeostasis.
