Wikiera Beata , Pesz Karolina , Petriczko Elzbieta , Nocon-Bohusz Julita , Urbanowicz Ewa , Walczak Mieczyslaw , Sasiadek Maria , Noczynska Anna

Background: Central precocious puberty (CPP) results from activation of the hypothalamic-pituitary-gonadal axis before the age of 8 years in girls and 9 years in boys. The molecular basis of the maturation of this axis is still poorly understood. The MRKN3 gene located in the Prader-Willi syndrome critical region (chromosome 15q11–q13), inhibit factors stimulating pulsative. GnRH secretion. In 2013 inactivating mutations in the MRKN3 gene were discovered...

Background: Cerebral infarction (CI) is a known vascular complication following treatment of suprasellar tumors. Risk factors for CI, incidence rate, and long-term prognosis are unknown for patients with childhood-onset craniopharyngioma (CP).Methods: MRI of 244 CP patients, recruited between 2007 and 2019 in KRANIOPHARYNGEOM 2007, were reviewed for CI. Risk factors for CI and outcome after CI were analyzed.<p class=...

Objectives: To reassess growth hormone (GH) status by the means of Insulin (ITT) and Glucagon tests (GL) in young adults with childhood-onset GHD.Methods: We present preliminary data of 67 subjects (25F, 42M) recruited from a single Center, in whom anthropometrics, ITT and GL stimulation tests and IGF-1 evaluations were undertaken at adult height achievement, at a mean age of 17.3±2.2 (range: 13.3-25.7). Subjects we...

The chimeric CYP21A1P/CYP21A2 and TNXA/TNXB gene deficiencies in patients with Congenital Adrenal Hyperplasia

Fanis Pavlos , Toumba Meropi , Katerina Chrysostomou Anna , Mousikou Maria , Nicolaou Stella , Kyriakou Andreas , Neocleous Vassos , A Phylactou Leonidas

Background: Congenital Adrenal Hyperplasia (CAH) is an autosomal recessive disorder with more than 90% of cases caused by defects in the steroid-21 hydroxylase (CYP21A2) gene. Such defects are the main cause of 21-hydroxylase enzyme deficiency that affects the biosynthesis of cortisol and aldosterone. The CYP21A2 gene is part of the RCCX module, which is located on chromosome 6p21.3, in the major histocompatibility complex (MHC) class III reg...

Introduction: Central precocious puberty (CPP) is due to premature activation of the hypothalamic-pituitary-gonadal axis. Mutations in the imprinted gene MKRN3 are the most common monogenic form of CPP. Recently, attention was directed to DLK1, another imprinted gene. Defects in this gene resulted to be a rare cause of CPP in girls and adult women with precocious menarche, obesity and metabolic derangement. We aimed to investigate a cohort of female and male p...

Background: The primary goal of GH treatment in GHD children and adolescents is to normalize height, in order to attain an adult height within the target height (TH) range.Aim: to investigate height improvement in GHD paediatric patients treated with GH in our Country.Subjects: 737 patients with isolated GHD (39.5% females) from 13 tertiary Centres for Paediatric Endocrine Care...

Does cervical medullary decompression have an impact on growth in children with achondroplasia?

Fava Daniela , Tedesco Caterina , Angelelli Alessia , Napoli Flavia , Pepino Carlotta , Pepe Alessia , Teruzzi Daniela , Pisati Angelica , Fay Cortella Maria , Binelli Maria , Maghnie Mohamad , Di Iorgi Natascia , Elsa Maria Allegri Anna

Background: Foramen magnum stenosis (FMS) is a life-threatening complication in children with achondroplasia (ACH) which may require cervicomedullary decompression (CMD). There is no evidence if FMS and CMD affects growth in children with ACH.Aim: To evaluate the impact of FSM and CMD surgery on anthropometric measurements in children with ACH.Methods: Sixty-five patients with ACH ...

Introduction: Recent studies have revealed the presence of zinc and the expression of zinc transporter (ZnT) family members in most endocrine cell types. Moreover it was demonstrated that the ZnT family plays an important role in the synthesis and secretion of many hormones like insulin. We studied the prevalence of ZnT8 Ab in patients with autoimmune thyroid diseases (AITD).Material and methods: The study was performed in the group consisting of 20 Grav...

Background: The patatin-like phospholipase domain-containing protein 3 (PNPLA3) I148M and the transmembrane 6 superfamily member 2 (TM6SF2) E167K polymorphisms have been recognized as the major risk polymorphisms for Non-Alcoholic Fatty Liver Disease (NAFLD). Data supported a close relationship of NAFLD with thyroid function both in adults and children. To investigate the influence of NAFLD and of its genetics on thyroid function.<p class...

Rosaria Umano Giuseppina , Cirillo Grazia , Rondinelli Giulia , Vittoria Foderini Maria , Ferrara Serena , Di Sessa Anna , Marzuillo Pierluigi , Santoro Nicola , Miraglia del Giudice Emanuele

Purpose: Leptin plays a key role in the regulation of body weight and other endocrine systems. Recently, impairment of leptin gene transcription due to genetic variations in a long-noncoding RNA, also referred as lncOb, has been described in mice. In humans, a correspondent polymorphism (rs10487505) has been associated with relatively low plasmatic leptin levels compared to obesity severity and with early obesity onset.Objectives...
