Peripheral and Hypothalamic Alterations in the Insulin-like Growth Factor (IGF) System in Response to High Fat Diet-induced Weight Gain

Guerra-Cantera Santiago , Díaz Francisca , Ros Purificación , Freire-Regatillo Alejandra , Torrecilla-Parra Marta , Barrios Vicente , Frago Laura , Chowen Julie A. , Argente Jesús

The insulin-like growth factor (IGF) system is fundamental for physiological processes such as growth and metabolism. In addition, in the brain it regulates glucose metabolism and neuroprotection. The IGF axis can be altered by nutritional status, but little is known regarding the effects of specific dietary components on this system.Our aim was to examine how high-fat diet (HFD) and low-fat/high sucrose diet (LFHSD) intake affect the central and circula...

Introduction: C-type natriuretic peptide receptor encoded by NPR2 gene stimulates chondrocyte differentiation and hypertrophy and extracellular matrix production within the growth plate. The phenotypical spectrum of NPR2 mutations is broad, from severe autosomal recessive acromesomelic dysplasia to milder autosomal dominant growth disorders. Some children with NPR2 variants are treated with growth hormone (GH), however, with the inco...

Use of Desmopressin for Bilateral Inferior Petrosal Sinus Sampling (BIPSS) in Pediatric Patients with Cushing Disease (CD)

Gil Silvia , Di Palma Isabel , Vaiani Elisa , Viterbo Gisela , Requejo Flavio , Ramos Javier Gonzalez , Lazzati Juan Manuel , Lubieniecki Fabiana , Rugilo Carlos , Ciaccio Marta

Introduction: BIPSS before and after desmopressin stimulation has been shown to be a useful tool for diagnosis of ACTH-dependent CD and negative magnetic resonance imaging (MRI)or positive MRI but inconsistent biochemical data, in adult patients. However, little is known about its usefulness in pediatric population.Objective: To evaluate the prevalence of negative MRI, the sensitivity of BIPSS before and after desmopress...

National Multidisciplinary Decision-Making Guideline for Children and Young People (Idiopathic Thickened Pituitary Stalk and/or Idiopathic Central Diabetes Insipidus

Cerbone Manuela , Bulwer Chloe , Ederies Ashraf , Vallabhaneni Kirtana , Ball Stephen , Kamaly Ian , Grossman Ashley , Gleeson Helena , Korbonits Marta , Nanduri Vasanta , Tziaferi Vaya , Jacques Tom , Visser Johannes , Spoudeas Helen A

Background: Thickening of the Pituitary Stalk (TPS) and/or Central Diabetes Insipidus (CDI) can occour in isolation or synchronously/metachronously in the same patient. Due to their rarity and wide spectrum of underlying aetiologies they represent a diagnostic and management conundrum.Aim: To develop a high-quality national multidisciplinary guideline for the assessment and management of children and young people (CYP) before their 19th birthd...

A Homozygous Pathogenic Variant in the TRHR Gene in a Boy Who Presented With Severe Familial Short Stature and Central Hypothyroidism

Šnajderova Marta , Plachy Lukaš , Strakova Veronika , Elblova Lenka , Dušatkova Petra , Zemkova Dana , Lebl Jan , Pruhova Štěpanka

Introduction: Congenital central hypothyroidism (CCH) is a rare disease with inappropriate thyroid hormone secretion due to impaired TSH stimulation. TSH levels are not elevated; the patients are not diagnosed in TSH-based newborn screening. Biallelic variants in TRHR gene (encoding TRH receptor) are one of four genetic defects known to cause isolated CCH (THRH, THSB, IGSF1, TBL1X). The phenotype is variable but generally mild (neon...

The Expression of Cytokines in SGA Children Throughout Lactation Allows to Characterize Early the Type of Cath-up

Diez-Lopez Ignacio , Sarasua Ainhoa , delHoyo Marta , Lorente Isabel , Segura Raquel Gomez de , Picon Minerva , Leniz Asier , Fernandez Alfredo , Puy-Portillo Maria

Up to 50% of children born SGA at 2 years have not made a correct catch up (by excess or defect), with repercussions on size, metabolic and cardiovascular alterations, DM, etc. The Project has developed a prospective cohort of SGA and seeks to study phenotypic, BQ and genetic differences that explain their different behavior.Material and methods: We study live births of single pregnancies in our Hospital during 2012–2014, and are classified accordin...

Germline and Somatic DICER1 Mutations in Familial Papillary Thyroid Carcinoma and Multinodular Goiter

Lumbreras Cesar , Chueca Maria Jesus , Arribas Laura , de Randamie Rajdee , Alonso Angel , Fernandez Pilar , Berrade Sara , Anda Emma , Regojo Rita Maria , Mendiola Marta , Moreno Jose Carlos

Background: The inheritable component of familial Papillary Thyroid Cancer (fPTC) was recently attributed to monogenic defects in a reduced number of genes including DICER1. DICER1 codes for a ribonuclease of the RNaseIII family essential for the biogenesis of microRNAs.Objective and hypotheses: We aimed to identify germline and/or somatic mutations in DICER1 in a familial pedigree with PTC, multinodular goiter (MNG) and other ...

Early Onset Obesity and Hyperphagia Associated with Defects in the GNAS Gene

Garcia Marta , Espinosa Nuria , Guerrero-Fernandez Julio , Salamanca Luis , Morais Ana , Gracia Ricardo , Elkoro Intza Garin , Casado Isabel Gonzalez , de Nanclares Guiomar Perez , Moreno Jose C.

Background: Imprinted genes are known to regulate fetal growth and a ‘parental conflict’ model predicts that paternally and maternally expressed imprinted genes promote and inhibit fetal growth, respectively. GNAS is a complex imprinted locus with multiple oppositely imprinted gene products. Maternal, but not paternal, G(s)alpha mutations lead to obesity in pseudohypoparathyroidism type IA (PHPIA). However, the disorder rarely causes severe obesity in infancy as pred...

Hyperphosphatemic Familial Tumoral Calcinosis: Novel Indication to Sevelamer Carbonate

Fuentes-Bolanos Noemi , Canovas Sanchez Laura , del Toro Codes Marta , Martinez Moya Gabriela , Natividad Pedreno Moises , de la Cruz Moreno Jesus

Background: Hyperphosphatemic familial tumoral calcinosis (HFTC) is a condition characterized by hyperphosphatemia and abnormal deposit of phosphate and calcium most often around the hips, shoulders and elbows and rarely in the brain.Case presentation: A four-year-old-girl from Arabian origin was referred to the regional paediatric endocrine clinic from the Orthopedics Team due to: recurrent calcinosis of the right calcaneus and incipient left wrist pain...
