Background: The adequacy of cortisol response in NCCAH has not been fully elucidated.Objective and hypotheses: To evaluate cortisol response to ACTH stimulation test in children and adolescents with NCCAH and possible heterozygosity for CYP21 gene molecular defects.Method: Data of ACTH stimulation test from 146 children and adolescents with clinical hyperandogenism were evaluated retrospectively. Cortisol responses to ACTH stimulat...

Background: It is now widely accepted that chemical pollutants in the environment can interfere with the endocrine system. The impact of endocrine disrupting chemicals on puberty disorders is concerned. bisphenol-A (BPA) has been measured in fetal plasma. There are different toxic effects with different doses of BPA.Objective and hypotheses: To observe vaginal opening day (VOD), hypothalamic kiss-1 gene and ovarian estrogen receptors (ER) gene expression...

Background: Generalised glucocorticoid resistance (Chrousos syndrome) is a rare inherited disease characterized by tissue insensitivity to glucocorticoids and associated with defects in human glucocorticoid receptor (hGR) gene (NR3C1, 138040). Despite of elevated serum and urine cortisol the patients do not develop clinical picture of Cushing syndrome but present with hyperandrogenia and hypertension.Case presentation: We present a case in which clinical...

Background: Follicle-stimulating hormone (FSH) plays a key role in reproduction. The G-protein coupled FSH receptor (FSHR), is expressed primarily in gonads, and specifically binds FSH. FSHR is also expressed in vascular endothelium, osteoclasts, adipose tissue, monocytes and rodent pancreatic islets. Elevated FSH levels are associated with development of obesity, insulin resistance, osteoporosis, and cardiovascular disease. In a recent study, we showed that h...

Introduction: Rare mutations of the ESR1gene, encoding the estrogen receptor alpha (ERα), have been shown to cause estrogen resistance in humans. To date, there are no effective therapeutic options. We report the case of a new inactivating mutation of ERα and provide evidence for a partial restoration of biological effects of estrogen.Methods: We performed clinical and biological phenotyping of the index case and sequenced the ESR1...

Background and aims: The low dose short corticotropin test (LCT) is the most frequently used test to diagnose glucocorticoid-induced adrenal insufficiency (GAI) in children. Result of the LCT must be interpreted with caution since stimulated peak cortisol (PC) thresholds depend on the assay and time of sampling. We evaluated the prevalence of GAI by the LCT using both 20 and 30 minutes sampling and cortisol measurements by the most recent Roche Elecsys Cortiso...

Introduction: Diagnosing growth hormone deficiency (GHD) in children is complex. Spontaneous growth hormone (GH) pulses during late night may influence the pituitary GH response to provocation tests. We evaluated refractoriness during arginine-insulin-tolerance test (AITT) when having a GH-peak during a short spontaneous nocturnal profile in children with short stature.Methods: Altogether 257 children 0-18 years were exa...

Background: in our days the case of reduction of bone mineral density becomes more common. This pathology can be detected in children and adolescents with obesity with the help of densitometry.Aim: to reveal the dynamics of body composition indicators in obese children.Methods: we examined 32 children with obesity in the University Hospital (Minsk) in 2020-2022 yrs. Their anthropom...

Timely recognition and treatment of neonatal hypoglycemia are important because of the potential for adverse neurodevelopmental outcomes. One of the major problems in infants born following a pregnancy complicated by diabetes is hypoglycemia. In addition, hypoglycemia occurs in infants of non-diabetic mothers. We conducted a retrospective cohort study including all infants who had hypoglycemia during the first day of life, between 1-9-2017 and 31-8-2020. We studied the relatio...
