Background: RARβ cooperates with Nur77 to in-vitro regulate HSD3B2 transcription. NUR77 expression parallels HSD3B2 expression with a much lower level in androgen-producing adrenocortical tissues (childhood virilizing adrenocortical tumours (VAT), fetal zone (FeZ) and zona reticularis, ZR). RARβ is down-regulated in starved, hyperandrogenic H295R cells. However, the mechanisms regulating this expression pattern and the relevance of RARβ to huma...

Background: To date at least 30 genes are known to be associated with idiopathic hypogonadotropic hypogonadism (IHH). Analysis of all these gene candidates by Sanger sequencing would be expensive, labour-intensive and time-consuming. Recent introduction of next-generation sequencing (NGS) enables simultaneous analysis of multiple gene targets making it an attractive approach in such conditions as IHHObjective and hypotheses: To study the spectrum of mole...

Background: Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) results from gain-of-function mutations in the AVPR2 gene coding for vasopressin receptor 2 (V2R). In contrast, nephrogenic diabetes insipidus (NDI) is caused by loss-of-function mutations in AVPR2. Here we describe and functionally characterize a novel mutation located in the seventh transmembrane domain of V2R. This mutation was identified in a boy suffering from water-induced hyponatrem...

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 ...

Aim: To develop a low cost formula as screening tool for identifying youths with overweight/obesity (OW/OB) at risk for impaired glucose tolerance (IGT).Methods and results: A retrospective observational study was performed in 1189 Caucasian youths with OW/OB aged 5-17 years, in whom information about family history for diabetes (FD), fasting glucose (FG), 2-hour glucose levels post-oral glucose tolerance test, alanine a...

Background/Aim: X-linked hypophosphatemia (XLH) is a rare disease caused by mutations in PHEX, leading to elevated FGF23 levels, hypophosphatemia and chronic renal phosphate wasting. Burosumab is a monoclonal antibody against anti-FGF23, which has been recently approved for treatment of XLH. Beyond clinical trials, little is known about its efficacy/safety in clinical practice which is the aim of study.Patients/Methods: ...
