Background: We analyzed characteristics of patients with stunting admitted at Endocrinology Department of Muratsan University Medical Settings, the only specialized center in Armenia. No similar study was carried out in this region.Objective and hypotheses: Patients (n=102) were evaluated prospectively.Method: The following parameters were used for statistical analysis- demographic information, diagnosis, anthropometric da...

Background: Prader-Willi syndrome (PWS) is a complex multisystem genetic disorder arising from lack of expression of paternally inherited imprinted genes on chromosome 15q11–q13. Hyperphagia represents one of the most serious symptoms of the PWS, leading to develop premature mortality.Objective and hypotheses: To compare orexigenic (ghrelin) and anorexigenic factor (brain derived neurotrophic factor (BDNF)) concentration in non-GH-treated obese pati...

Background: GNRHR gene mutations are responsible for development to normosmic idiopathic hypogonadotropic hypogonadism (iHH) and known to be the most frequent cause of this condition. Nevertherless, the reported frequency of GNRHR mutations in iHH patients estimated to be as low as 3-6%.Objective: To evaluate the frequency of GNRHR gene defects in a heterogeneous group of Russian patients with iHH and described the p...

Background: Mutations in PROP1 are the most common known genetic cause of congenital multiple pituitary hormone deficiency (MPHD).Objective and hypotheses: Aim of our study was to clinically and genetically characterize a cohort of Lithuanian patients with MPHD.Method: Seventy-six Lithuanian MPHD patients were tested for PROP1 gene by Sanger sequencing. Hormonal investigations, pituitary imaging and GH therapy wer...

The changes of the immune reactivity, the production of hormones and the neuroendocrinal regulation of immune homeostasis are the entities closely connected with the puberty. There is evidence for the role of cytokines in securing of intersystemic interaction as well as for the influence of reproductive hormones on the cytokine production. However, the question as to the role of cytokine in the formation of delayed puberty continues to be relevant.<stron...

Background: Several studies found a high prevalence of sleep disorders in PWS patients. It is assumed that Prader-Willi Syndrome (PWS) patients are at a high risk of sleep disordered breathing, such as obstructive sleep apnea (OSA), because of their childhood obesity, associated with muscle hypotonia, leading to upper airway collapse.Objective and hypotheses: We studied a group of PWS children (genetically confirmed, non-GH-treated) who performed complet...

Objective: To characterise clinical presentation of congenital isolated ACTH deficiency.Methods and results: Clinical and anthropometric data were obtained. Biochemical liver function parameters, blood glucose, insulin, TSH, free thyroxin (FT4), GH, cortisol, and ACTH levels were analyzed. POMC and TBX19 genes were analysed by Sanger sequencing. The girl was born at full-term with normal weight and length. The parents are cousins. At birth cra...

Background: Diamond–Blackfan anemia (DBA) is an inherited bone marrow failure syndrome, which presents with anemia in early infancy. Survival depends on blood transfusions, which in consequence lead to iron overload (IOL). The most common complications of IOL are hepatic cirrhosis, endocrinopathies and cardiomyopathy.Results: We present the case of 17 years old girl with DBA and IOL-associated endocrinopathies. Her treatment consists of multiple blo...

Idiopathic Ketotic Hypoglycemia (IKH) is the most common non-iatrogenic cause of hypoglycemia in children beyond infancy. The severity of the symptoms and frequency of hypoglycemic episodes may vary among the patients. The etiology of IKH is unclear; disturbances in gluconeogenesis, glycolysis and glycogenolysis were regarded as possible causes. Familial IKH recurrence is often observed, suggesting a genetic basis of glucose homeostasis dysregulation.We ...

Background: Prader-Willi syndrome (PWS) is a complex, multisystem disorder that arises from lack of expression of paternally imprinted genes on chromosome 15q11-q13. Its major clinical features include neonatal hypotonia, short stature, developmental delay, hyperphagia, childhood onset obesity, hypothalamic endocrinopathy and characteristic appearance. It is known that due to severe obesity PWS patients are prone to develop type 2 diabetes mellitus (T2DM), whi...
