Hormono-metabolic disorders in women with hypothalamic syndrome in the ontogenetic aspect

Abstract

Introduction. The rising incidence of obesity among children and adolescents has become a major public health problem. Problems of female reproductive function associated with obesity include menstrual irregularities, complications of pregnancy and childbirth, and infertility.Aim. To conduct a prospective analysis of carbohydrate, lipid metabolism, neuroendocrine regulation in women with primary infertility and hypothalamic syndrome of puberty.Materials and methods. Prospective, longitudinal study of adolescent girls (n=170) with hypothalamic dysfunction for 14.2±1.6 years, mean age was 14.41±0.26 years. The second stage of the study included an assessment of the hormonal status and metabolic changes in 86 women, of which 46 were fertile, 26 had primary infertility and 14 had secondary infertility, mean age was 21.89±1.15 years. Clinical and laboratory methods were used to study the indicators of lipid and carbohydrate metabolism, pituitary-ovarian and adrenal hormonal regulation systems, instrumental and functional research methods, as well as statistical analysis methods were carried out.Results. Among adolescent girls with hypothalamic dysfunction a high proportion of secondary amenorrhea − 31% (p=0.042) and metabolic syndrome − 86% was revealed, as well as a significant increase in follicle-stimulating hormone, testosterone, cortisol and a decrease in the concentration of progesterone, inhibin B, an increase in cholesterol, low density lipoproteins, triglycerides, the HOMA index, insulin and a decrease in high density lipoprotein cholesterol. We found a high proportion of polycystic ovary syndrome − 19.8%, polymenorrhea − 18.6%, oligomenorrhea − 19.8%, primary infertility − 30.2%, (p=0.001) in women with a history of hypothalamic obesity in the pubertal period. We determined a set of primary infertility predictors: the presence of triglyceridemia and hyperlipidemia in the puberty period (OR 9.5; 95%CI [1.7–51.9]) and hormone-dependent diseases in the reproductive period (OR 5.6; 95%CI [2.5–18.2]).Conclusion. In our opinion, timely prevention and correction of lipid metabolism disorders in adolescents, as well as early detection of hormone-dependent diseases in the reproductive period are promising for the prevention of reproductive disorders.
