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...

Background: Mutations in PROP1 gene are the most common known genetic cause of multiple pituritary hormone deficiency. It is characterized by somatolactotroph, thyrotroph, gonadotroph and sometimes corticotroph deficiencies and pituitary hyper- or hypoplasia. The karyotype 47,XYY occurrs in 1 in every 1000 live male birth. Some studies report that the phenotype of XYY syndrome includes tall stature, behavioral problems and low fertility.Objectiv...

Background: PROP-1 gene mutations are responsible for most of the cases of multiple pituitary hormone deficiencies (MPHD).Objective and hypotheses: We performed to evaluate the final adult height (FAH) in a group of patients with a PROP-1 gene mutations. Twenty-five patients (11 males) with a PROP-1 gene mutation, not treated before, were recruited. All the patients had been treated with a fixed rhGH dose (0.033 mg/kg per day) for 10.5 years (7.0–11...

Background: The most common forms of maturity-onset diabetes of the young (MODY) are MODY-GCK and MODY-HNF1A. Prevalence of MODY in Russian population is unknown.Aims and objectives: To compare clinical laboratory characteristics of MODY-GCK and MODY-HNF1a in children and adolescents, to estimate prevalence of MODY.Method: 151 children and adolescents were screened for mutations in GCK and HNF1A. HbA1c, fasting and stimulated gluco...

Introduction: Type 1 diabetes mellitus (T1D) is the most common form of carbohydrate metabolism disorder in childhood. There are also monogenic forms of diabetes. In the world literature, there are isolated mentions of the combination of monogenic and autoimmune forms of diabetes mellitus.Clinical case: A 10-year-old obese patient presented with hyperglycemia. At hospitalization: height 168 cm, weight 87 kg, SDS BMI +3.0. Glycemia 14.4 m...

Mutations in HNF1A gene underlie the development of maturity onset diabetes of the young type 3 (MODY3). Mutations in ABCC8 gene are the cause of neonatal DM and the rare MODY12, which is clinically similar to MODY3. In these forms of MODY, there is a high sensitivity to sulfonylurea. Patient A, 17 y.o. He was born to woman with gestational DM. At the age of 12.5, fasting hyperglycemia of 13 mmol/l was detected. Insulin therapy was not prescribed due to the parent’s refu...

Background: Nowadays, single nucleotide polymorphisms in genes KISS1, KISS1R, MKRN3, DLK1 have been described as the leading cause of precocious hypothalamic-pituitary axis activation in children. Genetic testing in patients with hereditary forms of precocious puberty (PP) can expand our knowledge in underlying molecular mechanisms of the disease. The diagnosis of genetic bases is necessary for genetic counselling.Aim: T...

Background: Endothelial dysfunction is a macrovascular complication of type 1 diabetes. Children and adolescents with type 1 diabetes may suffer of endothelial dysfunction, irrespective of chronological age and disease duration.Objective and hypotheses: After evaluating the prevalence of early endothelial dysfunction, as measured by mean of reactive hyperaemia in adolescents with type 1 diabetes, at baseline and after 1-year follow-up, we started a 6-mon...

Pediatric obesity is constantly increasing and exposes to serious cardiovascular and metabolic risks. The first treatment against obesity is lifestyle change. Actually, any intervention seems to be effective on the evolution of this condition, especially in the long term. For this reason, the interest in non-pharmaceutical compounds is growing. Several studies mentioned the use of zinc and inositol as compounds acting on weight loss and insulin resistance. The aim of this stud...

Multiple Endocrine Neoplasia Type 1 (MEN1) is an inherited autosomal dominant disorder caused by mutations in the MEN1 tumor suppressor gene. Penetrance increases with age. It combines mainly hyperparathyroidism, adenomas of the pancreas and pituitary gland. The prevalence is about 2/100 000. Diagnosis in children is rare except in the case of family screening. We report the diagnosis of a familial MEN1 whose index case was an adolescent girl investigated because of hypoglycae...
