Cushing’s disease treatment results correlation with pituitary MRI in children

Yanar Eda , Makazan Nadezhda , Kareva Maria , Vorontsov Alexandr , Vladimirova Victoria , Peterkova Valentina ,

Objective: Transsphenoidal surgery (TSS) is a treatment of choice for Cushing`s disease (CD), whose effectiveness range is from 70 to 90%. Recurrence rate after successful treatment is about 25%. Preoperative predictors of remission and recurrence are still unexplored what leads to further investigations.Aim: Analysis of remission and recurrence rates of CD after radical treatment according to preoperative MRI....

Myokines - biologically active proteins produces and secretes by skeletal muscles in response to physical activity (PA). They play a role in lipid and glucose metabolism, myogenesis and osteogenesis, thermogenesis activity. Exercise-induced expression of myokines in adolescents with simple obesity insufficiently studied.Objective: to determine which intensity and duration of PA maximally changes the level of myokines (interleukin-6 (IL-6...

Background: Birth weight (BW) is associated with the development of obesity, insulin resistance and type-2 diabetes in adulthood. The results of studies on the correlation between BW and the severity of obesity and cardiovascular risk factors (CVRF) among obese children are contradictory. The objective of our study was to evaluate the association between birth weight and the presence of CVRF in genetically homogeneous group of obese children and adolescents.</...

Pediatric Cushing`s disease due to somatic USP8 mutations

Yanar Eda , Kareva Maria , Kolodkina Anna , Antysheva Zoia , Bogdanov Victor , Peterkova Valentina

Objective: Somatic mutations in the USP8 gene were discovered as the most common genetic defects in corticotropinomas with a frequency of 30 to 60% in adult patients. With regard to pediatric patients, establishing prevalence of USP8 mutations is still challenging due to the rarity of CD incidence in childhood.Aim: To determine the frequency of somatic genetic drivers of CD in a cohort of pediatric patients.<p class=...

Background: Congenital hyperinsulinism (CHI) is a heterogeneous group of disorders, characterized by hypoglycemia due to inappropriate insulin secretion. Despite huge progress in understanding the pathophysiology of CHI, its etiology remains unknown in about 30% of cases.Aim: To perform whole-exome sequencing in patients with CHI.Results: A total of 314 patients with congenital hyp...

Hypercalcitoninaemia in girl with pseudohypoparathyroidism type 1A.

Pankratova Maria , Pisareva Elena , Lyadova Olga , Chugunov Igor , Volevodz Nataliya , Bezlepkina Olga , Peterkova Valentina

Background: Pseudohypoparathypoidism (PHP) type 1A is a rare endocrine disorders caused by GNAS mutation. Patients phenotype with PHP type 1A include obesity, round facies, brachydactyly, subcutaneous ossifications, short stature. The resistance of action of parathyroid hormone (PTH) leads to hyperphosphatemia, hypocalcaemia and secondary hyperparathyroidism. Hypercalcitoninaemia has been described in limited patients with PHP without thyroid patholog...

Introduction: Central Precocious Puberty (CPP) has recently been described in patients with isolated or syndromic neurodevelopmental disorders, with greater attention from the scientific community. We carried out this study to compare the main aspects of non-isolated and isolated forms of CPP.Methods: We conducted a retrospective monocentric study, collecting all treated cases of CPP from 1st January 2013 to 31 December ...

Neonatal diabetes mellitus in a patient with a novel heterozygous mutation in GATA6

Sechko Elena , Raykina Elizaveta , Kuraeva Tamara , Laptev Dmitriy , Bezlepkina Olga , Peterkova Valentina

Transient neonatal diabetes mellitus (TNDM) occurs in 50-60% of all cases of neonatal diabetes mellitus (NDM). The most common cause of TNDM (70%) is almost invariably associated with defect in chromosome 6 and mutations in the KCNJ11, ABCC8, INS, NHF1B etc. genes. TNDM is caused by mutations in the GATA6 gene in rare cases. This gene encodes a transcription factor that is important for the development of the hematopoietic, cardiac and gastrointestinal systems.<p class="ab...

Introduction: Severe insulin resistance due to insulin receptor mutation is usually diagnosed at the neonatal period (Donohue and Rabson-Medenhall syndromes), or later in a type A insulin resistance syndrome. We report here two cases of insulin receptor mutation whose presenting signs were less noticeable.Observation: A 13-year-old girl was referred for short stature (Height −2.5 SDS) with SGA (birth length 44.5 cm, at gestational age 41 weeks). Cl...

Introduction: Multinodular goiter (MNG) is a common disorder of the thyroid gland, characterized by thyroid enlargement due to the development of multiple hyperplastic nodules. It is infrequent in children. Here, we present the case of two families with novel DICER1 mutations and familial history of nodules in adolescence.Observations: A 10-year-old female presented a MNG. TSH, Free T3, Free T4 were in the normal range and thyroid autoantibodies were neg...
