Chronic autoimmune thyroiditis (cAIT) and Graves’ disease (GD) is the most common autoimmune disorders in children, associated with induction of inflammation and autoimmunity process. OPG, a cytokine receptor which mediates suppressive effect on osteoclastogenesis and its soluble ligand RANKL (sRANKL) are regulators of inflammation and may be a link between bone, autoimmune disease, and vasculature.Aim of the study: We hypothesized that cytokines OP...

Background: Autoimmune thyroid diseases (AITD) are one of the most common organ-specific autoimmune disorders, of which Hashimoto’s thyroiditis (HT) and Graves’ disease (GD) are 2 of the most common clinical expressions. HT is characterized by hypothyroidism (hypoT) that results from the destruction of the thyroid by specific T cell-mediated cytotoxicity. In contrast, GD is characterized by hyperthyroidism (hyperT) induced by thyrotropin receptor-specific stimulatory...

Background: Chronic autoimmune thyroiditis (cAIT) and Graves’ disease (GD) are the most common autoimmune disorders in children. Proinflammatory cytokine such as IL-6 has been generally associated with the induction of inflammation and autoimmunity. Osteoprotegerin, a soluble glycoprotein and a member of the tumor necrosis factor receptor (TNFR) family, play an important role in bone homeostasis and in vasculature.Objective and hypotheses: The aim o...

Background: Chronic autoimmune thyroiditis (cAIT) leads to hypothyroidism due to T cell-mediated cytotoxicity in most cases. By contrast, Graves’ disease (GD) with thyrotropin receptor stimulatory autoantibodies cause hyperthyroidism. OPG a cytokine receptor which mediates suppressive effect on osteoclastogenesis is a key regulator of inflammation and may be a link between bone, autoimmune disease and vasculature.Objective and hypotheses: Cytokines ...

Background and objective: Given phenotype variability as well as limited utility of conventional endocrine investigations in reaching the diagnosis in a 46,XY patient suspected of a disorder of sex development (DSD), there is an increasingly stronger argument for considering targeted genetic sequencing at an earlier stage of the evaluation process. This study focused on identifying the relationship between clinical examination, endocrine and radiological assessment, as well as...

Delayed puberty (DP) in boys is considered the most common hypoandrogenia of puberty. It should be noted that DP adversely affects physical development, body formation and the health status of adolescents. The heterogeneity of the population of adolescents with DP has led to a differentiated approach and the allocation of the following three clinical options (CO) of DP: 1 - DP, accompanied by growth retardation; 2 - DP without significant deviations in physical development; 3 ...

Background: Pseudohypoparathyroidism 1A, newly classified as inactivating PTH/PTHrP signaling disorder type 2 (iPPSD2), is defined by resistance to parathyroid hormone, short stature and early-onset obesity. Short stature is caused by skeletal dysplasia and additionally, in some cases, also by the coexistence of growth hormone deficiency, as other hormonal resistances might be present (e.g. thyroid-stimulating hormone, growth hormone releasing hormone (GHRH), ...

Objective: Determination of changes in metabolic status and vitamin D concentrations in obese children.Methods: We examined 210 children in the University Hospital (Minsk) from 2021 to 2022 yrs. Their anthropometric parameters (height, weight, body mass index (BMI)) were determined. Blood levels of vitamin D, OPG, insulin were determined. All children were divided into 2 groups: group 1 children with morbid obesity (MO) ...

Background: Mammalian puberty is initiated by the pulsatile release of gonadotropin-releasing hormone (GnRH) from hypothalamic neurons. Enhanced at puberty (Eap) 1 is a transcription factor within this regulatory network integrating exogenous and endogenous informations, e.g. weight. Recent studies indicate an epigenetic regulation of the pubertal process.Objective and hypotheses: This study investigates if overweight modifies epigenetic marks i...

Objective: determination of changes in metabolic status and vitamin D concentrations in obese children.Methods: We examined 221 children in the University Hospital (Minsk) from 2019 to 2021 yrs. Their anthropometric parameters (height, weight, body mass index (BMI)) were determined. Blood levels of vitamin D, insulin were determined. All children were divided into 2 groups: group 1 children with morbid obesity (MO) - 159...
