Clinical and laboratory characteristics of arginine vasopressin resistance and high carrier frequency of a novel homozygous variant p.R113C in the AQP2 gene among Buryats

Makretskaya Nina , Nanzanova Ulyana , Hamaganova Irina , Eremina Elena , Filatova Alexandra , Skoblov Mikhail , Tiulpakov Anatoly

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...

Eremina Irina , Kuraeva Tamara , Zilberman Lubov , Peterkova Valentina

Purpose: To assess the prevalence of pancreatic autoantibodies (Ab) and their impact on the course of type 2 diabetes mellitus (DM2) in adolescents.Materials and methods: ICA, GADA, IA-2 and IAA were measured in 66 patients with DM2. Depending on the presence of autoantibodies (Ab) patients were divided into 2 groups: Ab- and Ab+. HLA-typing was carried out in 45 patients. The secretion of C-peptide in the standard carbohydrate brea...

Combination of mutations in the HNF1A and ABCC8 genes: clinical polymorphism in members of the same family.

Eremina Irina , Raykina Elizaveta , Titovich Elena , Peterkova Valentina , Laptev Dmitry

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...

Investigation of Iodine Deficiency in the North of Siberia

Osokina Irina

Introduction: Siberia traditionally belonged to iodine-deficient regions. Cessation of iodine prevention in the 1990-s promoted the increase of iodine deficiency disorders (IDD) in Siberia. For iodine prophylaxis now is used iodized salt, and iodine preparations.The Aim: To estimate the iodine deficiency, the prevalence of IDD and the effectiveness of iodine prophylaxis in the North of Krasnoyarsk territory.<p class=...

Serum Catecholamines in Children With Type 1 Diabetes Mellitus

Osokina Irina

Background: young children with type 1 diabetes mellitus (DM1) have a tendency to recurrent hypoglycemia. Increased sensitivity to insulin in young diabetes patients may be associated with features of secretion of catecholamine, particularly adrenaline.The aim: to explore the basal levels of catecholamine (epinephrine, norepinephrine, and dopamine) in serum of young children with type 1 diabetes mellitus to identify of p...

A 16-Year-Old Girl with Prader-Willi Syndrome and Type 2 Diabetes Mellitus

Osokina Irina

Background: Prader-Willi syndrome (PWS) is a complex genetic disorder with implications on the endocrine and neurologic systems, metabolism, and behavior. Early in life, PWS is characterized by hypotonia and failure to thrive, followed by obesity and hyperphagia. Patients with PWS develop hypothalamic dysfunction which may lead growth hormone deficiency, hypogonadism, hypothyroidism, adrenal insufficiency and poor bone mineral density. Traditionally, obesity i...
