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...

We described a family in which MODY-GCK was detected in 6 people and its course varied.Materials and methods: The diagnosis of GCK-MODY was verified by the proband and his relatives on the basis of direct automatic sequencing and sequencing by Sanger.Results: Proband – a boy of 12 years, diabetes mellitus (DM) type 1 is diagnosed at the age of 11 years. He felt polydipsia, polyuria. Body weight was normal, he has not any disea...

Background: Congenital nephrogenic diabetes insipidus (arginine vasopressin resistance) is a rare inherited disorder characterized by insensitivity of the kidney to the antidiuretic effect of vasopressin. About 90% cases nephrogenic diabetes insipidus is an X-linked recessive disorder caused by variants in the AVP V2 receptor gene (AVPR2). In the remaining cases (10%) the disease is autosomal recessive or dominant and, for these patients, variants in ...

Background: 5-α-reductase type 2 enzyme catalyzes the conversion of testosterone into dihydrotestosterone, a potent androgen responsible for male sexual development during the fetal period. From 2017 to 2019, a homozygous hg38_chr2:31529414 C>T variant in SRD5A2 gene have been identified in 3 unrelated patients with DSD 46,XY of Buryat origin. The variant has been previously reported in one patient from China (Song et al, 2019) and l...

Background: According to the World Health Organization, the social determinants of health, the conditions in which people are born, grow, live and work – significantly influences on health. The CAF Foundation, the Endocrinology Scientific Center and the Institute for Family Health under the Alfa-Endo Program studied prevalence of some social determinants in families of children with type 1 diabetes mellitus.Objective and hypotheses: Investigate soci...

Background: Rare metabolic bone diseases (RMBD) are at the crossways of Endocrinology, Nephrology, Orthopaedic surgery and Rheumatology. Most of RMBD lead to short stature, bone pain, tooth anomalies, leg deformities, bone fragility and disability of variable importance. The organization of care varies immensely amongst European countries. Several European networks dedicated to RMBD already exist, supported by societies such as ESPE, ECTS or research grants, albeit their focus...

Introduction: A natiowide screening for Congenital Hypothyroidism (CH) was introduced 1996 in Russian Federation and Saratov Region. Revelation of the incidence of CH is of great value at the background of moderate iodine deficiency existing in Saratov and Saratov Region. Neonatal screening is an effective method for early detection of congenital hypothyroidism, a disorder that requires the prompt initiation of the treatment, in order to prevent the subsequent...

Viral infections may increase the risk of developing type 1 diabetes (T1D), and recent reports suggest that Coronavirus Disease 2019 (COVID-19) might have increased the incidence of pediatric T1D (M. Rahmati et al., 2022). In general, the course of viral infection in children is mild, the question of the long-term effects of COVID-19 on a child and adolescent, in particular, on pancreatic beta cells, remains unclear.Purpose: To ...

Background: Borderline precocious and normal-onset puberty can show slow or fast course. The fast development of pubertal signs can be resulted in decrease in final height (FH) via accelerated growth and bone maturation.Objective and hypotheses: To study the effectiveness of GnRHa in improving FH in girls with advanced bone age (BA) and decreased predicted height (PH) in borderline early or normal physiological puberty.Method: 135 ...

Background: Recently, mutations in the maternally imprinted MKRN3 gene have been associated to familial idiopathic central precocious puberty (iPPC). The clinical phenotype and the frequency of these mutations are poorly described.Objective and hypotheses: Delineate the frequency of MKRN3 mutations in iPPC and perform a genotype–phenotype correlation in MKRN3 mutated patients.Method: 59 index cases with iPPC have been included...
