Global recall of a growth hormone jet delivered device: experiences with children forced to switch from a needle free system to a growth hormone device with needle.

P. van Eck Judith , S. Renes Judith , J.C. Sas Theo , L.T. van den Akker Erica , C.M. van der Kaay Daniëlle

Introduction: Growth hormone (GH) treatment is essential for growth in children with GH deficiency. Also short children born small for gestational age (SGA), and children with syndromes like Turner Syndrome (TS), Noonan Syndrome (NS) and Silver Russel Syndrome (SRS) can benefit from GH treatment. For children with needle anxiety GH delivered by a jet device can be a solution for the daily subcutaneous treatment for many years. In 2021, a global recall of the o...

IHH gene variant causing short stature and minor skeletal disorders

García-Zarzuela Ana , Domínguez-Riscart Jesús , Rodriguez-Barrios Carmen , Morales-Pérez Celia , Karen-Heath Emma , Mª Lechuga-Sancho Alfonso

Introduction: Short stature is a frequent reason for consultation in the paediatric age group. After appropriate clinical, radiological and laboratory evaluation, up to 60-80% of children are classified as idiopathic short stature (ISS) because no underlying cause can be found. Nowadays, the spreading of molecular is revealing that many of the patients initially classified as TBI, have variants in genes involved in the growth plate development. IHH gene is inv...

Congenital Hypopituitarism and Diabetes Insipidus with Normal Radiological Pituitary Gland and a Mutation in IRF2BPL.

Jesús Dabad Moreno María , Ruiz Cano Rafael , Carmen Carrascosa-Romero María , Cerdán Oncala Sandra , Belén Delgado García Ana , De las Heras Gómez Lucía

Background: Congenital hypopituitarism (CH) is a group of disorders characterized by deficiencies in one or more hypophyseal hormones and a marked variability in genotype-phenotype correlations. Central diabetes insipidus (DI) is caused by a decreased release of ADH and results in a variable degree of polyuria. Their association is normally found in congenital cerebral midline abnormalities, such as septo-optic dysplasia.Objectiv...

Age and Gender-Specific Reference Data for High-Resolution Magnetic Resonance Based Musculoskeletal Parameters in Healthy Children and Young People

Elsharkasi Huda M. , Chen ¹Suet C. , Steell Lewis , Joseph Shuko , Abdalrahman Naiemh , Johnston Blair , Foster John E. , Wong Sze C. , Ahmed S. Faisal

Background: The need to understand the relationship between bone, muscle, and fat within the bone-muscle unit has recently gained great prominence. Although high resolution (HR) MRI is a non-invasive imaging modality that can provide this information, there is limited expertise in children and young people.Objectives: To establish MRI-based normative data for bone, bone marrow adiposity and muscle adiposity in children a...

Circulating Growth-and-Differentiation Factor-15 in Early Life: Relation to Prenatal and Postnatal Size

Díaz Marta , Campderrós Laura , López-Bermejo Abel , de Zegher Francis , Villarroya Francesc , Ibáñez Lourdes

Background: Growth-and-differentiation factor-15 (GDF15) is a regulator of energy homeostasis, and is used as biomarker of several pathological states.Objectives: To assess longitudinally GDF15 concentrations in a cohort of infants born either appropriate- (AGA, n=70) or small-for-gestational-age (SGA, n=33), the latter known to be at increased risk for central adiposity and metabolic alteration...

Craniosynostosis in Inactivating PTH/PTHrP Signaling Disorder 2: A Non-Classical Feature to Consider

Riaño-Galan Isolina , Rothenbuhler Anya , Debza Yahya , Barosi Anna , Mantovani Giovanna , Perez de Nanclares Guiomar , Linglart Agnès

Classic features of inactivating PTH/PTHrP Signaling Disorder 2 or 3 (iPPSD2, iPPSD3), i.e. former pseudohypoparathyroidism include multi-hormone resistance, short stature, subcutaneous ossifications, brachydactyly, and early-onset obesity and a molecular defect at the GNAS region. In addition, patients may present with less-known features including craniosynostosis (CSO).Objective: To describe the prevalence of CSO in a cohort ...

Analysis of Hypothalamic Metabolic Circuits after Normalization of Body Weight in Mice That Had Been Obese Due to High Fat Diet Intake

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

The obesity epidemic continues to be a dramatic problem in the developed world despite attempts to curtail its rise. Reducing energy intake and/or increasing energy expenditure can result in weight loss; however, if one returns to their poor lifestyle habits the previous weight is not only recuperated, but often surpassed.We hypothesized that although a normal body weight may be achieved, the hypothalamic circuits controlling appetite and energy expendit...

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...

PAPP-A2 Deficiency Induces Sex-Specific Changes in Hydroxyapatite-(CaOH) Crystallinity and the Effects of IGF-1 on Bone Composition in Adult Mice

Vargas Antonio , Rubio Leticia , Rivera Patricia , Christians Julian , de Fonseca Fernando Rodríguez , Chowen Julie , Suárez Juan , Argente Jesús

Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a regulator of IGF-1 availability, causes postnatal growth failure in humans and mice, at least in part through dysregulation of bone size and density. The present study aimed to determine the effects of Pappa2 gene deletion and the response to recombinant murine IGF-1 (rmIGF-1) on femur microstructure and composition. Hydroxyapatite-related crystallography and ionic substitutions were analyzed by X-ray p...

PAPP-A2 Deficiency Results in Sex-Dependent Modifications in Hypothalamic Regulation of Energy Homeostasis

Rivera Patricia , Vargas Antonio , Bonsón Javier , Christians Julian , Rodríguez de Fonseca Fernando , Chowen Julie , Suárez Juan , Argente Jesús

Pregnancy associated plasma protein (PAPP)-A2 is an insulin-like growth factor (IGF) binding protein (BP) protease that regulates IGF-1 availability affecting postnatal growth. Mutations in human PAPP-A2 cause short stature and changes in bone size and mineral density. The present study aimed to characterize the effects of constitutive Pappa2 gene deletion on hypothalamic regulation of energy homeostasis in adult male and female mice. In addition to being sho...
