Actuality: Standard methods for determining the compensation of the disease don't always reliably reflect the level of the glycemic control of the patient, which leads to decompensation diabetes and reduce the quality and duration of life for patients. Evaluation of glycemic variability indices allows the physicians to predict the risk of developing life-threatening conditions and compensate the diabetesAim: To condu...

Next Generation Sequencing Results in 142 Patients with Congenital Hyperinsulinism

Gubaeva Diliara , Melikyan Maria , Vasiliev Eugeny , Petrov Vasily , Tiulpakov Anatoly

Congenital hyperinsulinism (CHI) is a life-threatening disorder characterized by hypoglycemia due to dysregulated secretion of insulin from pancreatic β-cells. Genetic diagnosis is essential for patient management. NGS technologies give the ability to generate large amounts of sequence data in a relatively short amount of time. We report next generation sequencing (NGS) results in 142 patients (66 boys, 76 girls) with CHI seen at Endocrine Research Centre (Moscow...

Artificial Neural Networks for Prediction Final Height in Children with growth Hormone Deficiency

Gavrilova Anna , Nagaeva Elena , Rebrova Olga , Shiryaeva Tatiana , Peterkova Valentina

Background: Mathematical models predicting final height (FH) and its standard deviation score (SDS) in children with growth hormone deficiency is an important tool for clinicians to manage treatment process. Previously developed models do not have enough accuracy or are not good enough for practical use.Objective and hypotheses: We used four binary and seven continuous predictors available at the time of diagnosis and start of therapy and developed multi...

Long-Term Cognitive Effects from Dexamethasone-Treated Pregnancies

Shaytarova Anna , Khramova Elena , Suplotova Lyudmila

Background: In most countries of the world the prenatal glucocorticoid treatment to prevent reproductive losses in hyperandrogenic pregnancies has been found non-efficient. In Russia, up to present, dexamethasone has been listed in the standard threapy of pregnancy noncarrying risk of hyperandrogenic women. Simultaneuously, during the last decade the safety of treating pregnant women with synthetic glucocorticoids has been the subject-matter of intense debates considering poss...

Improvements in Bone Mineral Density in Girls of Prepubertal Age with Turner Syndrome

Malievsky Oleg , Volevodz Natalya , Peterkova Valentina

Background: Patients with Turner’s syndrome (TS) develop osteoporosis, resulting from chromosomal deficiency and estrogen deficiency by gonadal dysgenesis.Objective and hypotheses: The aim of this study was to assess bone mineral density (BMD) and parameters of bone remodeling during somatropin therapy in prepubertal girls with TS.Population and/or methods: We examined 22 girls with TS of the age of 11–15 years (the mean ...

Klippel-Feil Syndrome and Thyroiditis: a Case Report

Guidoni Elisa , Scarinci Renato , Municchi Giovanna

Background: Klippel–Feil syndrome (KFS) is characterized by congenital fusion of cervical vertebrae and has a prevalence of 1:50 000. The phenotypic expression is variable, sometimes presenting with extraskeletal symptoms.Case report: A girl was referred at the cronological age (CA) of 10.3 years with a suspected diagnosis of Turner syndrome, due to the presence of webbed neck and progressive deceleration of growth velocity. The girl, born in Russia...

Experience with Molecular Diagnosis in 48 Cases of Neonatal Diabetes Mellitus Using Targeted Next-Generation Sequencing

Tikhonvich Yulia , Vasilyev Evgeny , Petrov Vasily , Malievsky Oleg , Petryaikina Elena , Ribkina Irina , Stotikova Olga , Tiulpakov Anatoly

Background: Neonatal diabetes mellitus (NDM) comprises a group of monogenic disorders caused by mutations in genes involved in pancreatic development or insulin secretion. Accurate and rapid molecular diagnosis of NDM is pivotal for making decision on the treatment strategy. Next-generation sequencing (NGS) allows simultaneos analysis of several candidate genes, which facilitates the diagnostic procedure in NDM.Objective and hypotheses: To summarise our ...

Targeted Next-Generation Sequencing Demonstrates High Frequency of ‘Dyshormonogenesis Genes’ Mutations in Severe Congenital Hypothyroidism

Makretskaya Nina , Bezlepkina Olga , Kolodkina Anna , Kiyaev Alexey , Vasilyev Evgeny , Petrov Vasily , Kalinenkova Svetlana , Duhoreva Olga , Malievsky Oleg , Dedov Ivan , Tiulpakov Anatoly

Background: 80–85% of cases of congenital hypothyroidism (CH) are shown to be due to thyroid dysgenesis, while 15–20% are due to dyshormonogenesis. At least 12 candidate genes are associated with congenital hypothyroidism (CH), however its molecular basis is defined in fewer than 10% of the patients (ESPE consensus, 2014). Recent studies suggest that using a next generation sequencing (NGS) approach may increase the mutation yield in CH.Objecti...

Screening of Mutations in Idiopathic Hypogonadotropic Hypogonadism Using a Targeted Next-Generation Sequencing Approach

Kolodkina Anna , Kareva Maria , Kalinchenko Natalia , Raygorodskaya Nadezhda , Malievsky Oleg , Fidelina Olga , Vasilyev Evgeny , Petrov Vasily , Naumova Maria , Tiulpakov Anatoly

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...
