Introducion: Autoimmune thyroid diseases (AITDs): Hashimoto's thyroiditis (HT) and Graves’ disease (GD) are common chronic autoimmune endocrine disorders in children. The mechanisms leading to the development of these diseases remain unknown, however scientific reports indicate that in addition to environmental factors, genetic background plays an important role. In our previous studies, we showed that some polymorphisms of the genes for IL2RA, FAIM...

Background: The period of 0–6 month of life is a short window for postnatal testicular maturation and the diagnostic of reproductive disorders.Objective: To evaluate the functional condition of the hypothalamo-pitutary-gonadal axis in 1–3 months boys with cryptorchidism.Method: 51 boys ages 1–3 months with cryptorchidism were examined: group 1–30 boys with unilateral inguinal retention testes and group 2–21...

Background: The prevalence of congenital adrenal hyperplasia (CAH) in European countries is reported as 1:10–15 000. It depends on the quality of its diagnostics and efficacy of neonatal screening (NS). In Ukraine the NS was started in 2012.Objective and hypotheses: This is the first study of CAH epidemiology in children 0–18-year-old in Ukraine.Method: In 2013 it was created a database (DB) of Ukrainian children with CAH...

Background: Turner syndrome (TS) is the most well-known and common chromosomal disorder accompanied by delayed growth. According to the Ukrainian national register (UNR) of children with dwarfism the growth retardation is common for all girls with TS.Objective and hypotheses: The aim of the study was to determine the growth parameters of TS girls different age and karyotype, before GH treatment.Method: According to the UNR it was p...

Background: Turner syndrome (TS) is one of the most common genetic disorders associated with abnormalities of chromosome X that occurs in different populations with a frequency of 25–210 per 100 000 female live births.Objective and hypotheses:: The aim of this study was to investigate the prevalence of TS in ukrainian children, as well as frequency variations of karyotype and age of primary diagnosis of TS.Method: We analysed ...

Background: Mesoderm-specific transcript (MEST) is an epoxide α/β-hydrolase protein with catalytic activity that is determinant for the development of adipocytes. The MEST gene is an imprinted gene transcribed only from the paternal allele. Although the mechanism by which MEST overexpression augments fat accumulation and storage in adipocytes has not been fully elucidated, frequent subcellular contacts between MEST-positive endoplasmic reticulum, mi...

Type 1 diabetes (T1DM) in childhood is a highly prevalent disease, with incidence oscillating around 17.6/100000. However, incidence is higher in some communities (25.5/100,000), as it is in the case that concerns us. Diabetic ketoacidosis (DKA) is a complication usually recorded in 25–40% of cases but has been as high as 55% in studies of children under 5 years old. (T1DM) is an associated autoimmune disease to other precursor autoimmune pathologies.<p class="abstext...

Background: Growth hormone plays a primary role in stimulating postnatal growth by way of insulin-like growth factor 1 (IGF1) which is produced in the liver in response to GH. A deficiency of GH arrests maturation during childhood, and the stature of such subjects is generally much shorter than the average stature. However, some cases of GH deficiency attain normal stature as adults.Case presentation: A 20 years old man was referred for a further evaluat...

Introduction: Steroidogenic factor-1 (SF1), encoded by the NR5A1 gene, regulates several genes involved in male sexual determination, such as SOX9 and AMH, cholesterol mobilization and synthesis of a number of steroidogenic enzymes, like 3βHSD, and androgen biosynthesis, like INSL3. Mutations in NR5A1 have been associated to a broad phenotypic spectrum in 46, XY subjects, including pure gonadal dysgenesis, infertility, anorchia...

Background: Animal models of insulin-dependent diabetes show hyperactivity of hypothalamus–pituitary adrenal (HPA) axis, independently of hypoglycaemia. Few data exists regarding type 1 diabetes (T1D) in children.Objective: To describe HPA axis activity according to the anxiety levels in prepubertal T1D children.Method: Prepubertal T1D children and siblings of T1D children (controls) were included. State-Trait Anxiety Inventor...
