Ghrelin and Brain-Derived Neurotrophic Factor in Children with Prader-Willi Syndrome

Bogova Elena , Volevodz Natalya , Peterkova Valentina

Background: Prader-Willi syndrome (PWS) is a complex multisystem genetic disorder arising from lack of expression of paternally inherited imprinted genes on chromosome 15q11–q13. Hyperphagia represents one of the most serious symptoms of the PWS, leading to develop premature mortality.Objective and hypotheses: To compare orexigenic (ghrelin) and anorexigenic factor (brain derived neurotrophic factor (BDNF)) concentration in non-GH-treated obese pati...

High Prevalence GnRH Receptor Mutations in Russian Patients with Idiopathic Hypogonadotropic Hypogonadism

Frolova Elena , Makretskaya Nina , Kalinchenko Natalya , Kolodkina Anna , Zubkova Natalya , Petrov Vasiliy , Vasilyev Evgeniy , Tiulpakov Anatoly

Background: GNRHR gene mutations are responsible for development to normosmic idiopathic hypogonadotropic hypogonadism (iHH) and known to be the most frequent cause of this condition. Nevertherless, the reported frequency of GNRHR mutations in iHH patients estimated to be as low as 3-6%.Objective: To evaluate the frequency of GNRHR gene defects in a heterogeneous group of Russian patients with iHH and described the p...

Congenital hypothyroidism: outcome of a 26 year screening (1996-2021)

Svinarev Michail , Kurmacheva Nataliia , Gumeniuk Olga , Chernenkov Yuriy , Aranovich Vera

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...

The impact of covid-19 pandemic on the incidence type 1 diabetes in children

Kurmacheva Nataliia , Svinarev Michail , Chernenkov Yuriy , Gumeniuk Olga , Aranovich Vera

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 ...

Analysis of the GHR gene poly¬morphism in a non-disgenetic 46,XY DSD cohort without molecular diagnosis.

Celeste Mattone Maria , Perez Garrido Natalia , Costanzo Mariana , Hidalgo Lorena , Berger Malena , Zoff Luciana , Sonia Baquedano Maria , Ramirez Pablo , Berensztein Esperanza , Ciaccio Marta , Marino Roxana , Belgorosky Alicia , Guercio Gabriela

Background: Being born small for gestational age (SGA) is an associated condition to nonspecific 46,XY DSD (without molecular diagnosis and with no specific disorders of undermasculinization). However, the underlying mechanism of the relationship between the presence of genital abnormalities and intrauterine growth restriction is unknown. The GH-IGF system is crucial for sex differentiation in mice and in humans, members of this system were detected in embryon...

Disorders of sex development (DSD) are those congenital conditions in which development of chromosomal, gonadal, or anatomical sex is atypical. The aim of this study was to characterize the histology of 46,XX DSD prepubertal gonads. We studied 25 gonads of fourteen 46,XX DSD patients. The age of biopsy/gonadectomy was 1.17 (0.08–4.17) years (median and range). Molecular studies confirmed the absence of SRY by PCR and/or MLPA in blood samples of all patients and i...

Background: In Androgen insensitivity syndrome (AIS) is a hereditary disease in which AR mutations in 46,XY patients present with partial (PAIS) or complete (CAIS) defects in virilisation.Objective and hypotheses: The aim was to analyze the effect of lack of androgen action in germ cell (GC) health and survival along postnatal development, previous to Sertoli cell (SC) pubertal maturation.Method: The histological features and quant...

Background: Carriers of germline DICER1 mutations are predisposed to a rare cancer syndrome, the DICER1 syndrome, associated with tumors such as pleuropulmonary blastoma (PPB), ovarian Sertoli-Leydig cell tumors (SLCT), multinodular goiter (MNG), cystic nephroma (CN), embryonal rhabdomyosarcoma (ERMS) or primitive neuroectodermic tumor. DICER1 is involved in the generation of microRNAs (miRNAs), short, double-stranded, non-coding RNAs that modulate gene expression at ...
