Objectives: GH deficiency (GHD) and small for gestational age (SGA) status are associated with cardiovascular risks. We therefore investigated antiatherogenic effects of GH.Methods: Subfractions of LDL and HDL, lipoprotein-associated phospholipase A2 (Lp-PLA2), and high-sensitivity C-reactive protein (hsCRP) were measured at baseline, after 8 and 52 weeks of GH treatment in 51 short children born SGA (n=33) or with GHD (n=18).<p cla...

Leydig-Cell Tumour, a Rare Cause of LH-Independent Sexual Precocity in Boys

Gerard Maxime , Thomas-Teinturier Cecile , Bouvattier Claire , Mantel Anne , De Lambert Guenolee , Beaudoin Sylvie , Mussini Charlotte , Pierre Bougneres

Background: Leydig-cell tumours in children are rare, comprising only 4 to 9% of all primary testis tumours in prepubertal males. These boys present with isosexual precocious pseudopuberty characterized by increased testosterone and low gonadotropin levels. We describe two cases and will discuss differential diagnosis and pathogenesis.Case 1: C. was first referred at 8 years old for pubertal development with accelerated growth since 4 years of age. His v...

Baseline Characteristics, GH Response, and Long term Evolution in 67 Patients with Pituitary Stalk Interruption According to the Initial Presentation

Bar Celine , Zadro Charline , Diene Gwenaelle , Oliver Isabelle , Pienkowski Catherine , Jouret Beatrice , Audrey Cartault , Sevely Annick , Tauber Maithe , Edouard Thomas

Background: Pituitary stalk interruption syndrome (PSIS) is a frequent cause of congenital hypopituitarism. Patients are initially referred for the evaluation of hypoglycemia during the neonatal period or growth retardation during infancy or childhood. PSIS are either associated with extra-pituitary malformations (EPM+) or isolated (EPM−).Objective and hypotheses: To compare baseline characteristics, GH response, and long term evolution in patients...

Effects of romosozumab on bone ultrastructure and density in a patient with primary osteoporosis caused by a novel heterozygous WNT1 mutation

Montero-Lopez Rodrigo , Blaschitz Alexandra , Tischlinger Katharina , Wimleitner Marlene , Hörtenhuber Thomas , Klinger Markus , Cejka Daniel , Högler Wolfgang

Background: Genetic defects in the Wnt signaling pathway lead to early-onset osteoporosis (EOOP). Romosozumab is a monoclonal antibody against sclerostin, an inhibitor of the Wnt/ß-catenin pathway. Romosozumab has shown great efficacy in adult osteoporosis, however its effect in patients with Wnt-related EOOP is unknown. In monoallelic loss-of-function WNT1 mutations, romosozumab could potentially stimulate the defective Wnt signaling pathway an...

Phenotype and genotype of children with biallelic GHRHR gene mutations: a Belgian case series

Van de Velde Simone , Boros Emese , Brunelle Chloë , Beckers Dominique , De Schepper Jean , Thomas Muriel , Heinrichs Claudine , Brachet Cécile

Background: Children with biallelic GHRHR gene pathogenic variants share a phenotype of growth failure starting in infancy and resulting in a proportionate short stature and bone age delay due to a complete isolated growth hormone (GH) deficiency. The genotype ranges from rare promotor mutations to the more frequent splicing mutations, some genotypes being specific to certain geographic areas. Diagnosis is mainly made around the age of 7 years and more often i...

Denosumab in the treatment of paediatric hypercalcaemia

Tischlinger Katharina , Blaschitz Alexandra , Hörtenhuber Thomas , Montero-Lopez Rodrigo , Wimleitner Marlene , Uday Suma , Crane Janet , Högler Wolfgang

Background: Hypercalcaemia has various etiologies and treatment is often challenging. Therapeutic options include aggressive fluid management, loop diuretics and antiresorptive drugs. Since both hypercalcaemia and bisphosphonates can cause acute kidney injury (AKI), bisphosphonates are not recommended in patients with renal impairment. Denosumab, an antiresorptive human monoclonal antibody, is not associated with AKI and offers a temporary treatment option. Ho...

Congenital hypothyroidism in children with Sotos syndrome

Cavarzere Paolo , Munari Stefania , Raitano Vincenzo , Gaudino Rossella , Nicolussi Principe Lara , Arrigoni Marta , Zoller Thomas , Antoniazzi Franco

Background: Congenital Hypothyroidism (CH) is the most common neonatal endocrinologic disorder and one of the most preventable causes of mental retardation and neurological alterations in children. The incidence of CH lies between 1 in 2000-3000 newborns. The replacement therapy with levothyroxine (LT4) should be started immediately since studies show that a rapid normalization of TSH and fT4 optimizes the neurodevelopmental outcome. Infants with Down syndrome...

Childhood Obesity and Iron Metabolism

Sousa Bebiana , Galhardo Júlia

Introduction: Hypoferraemia is the most common nutritional deficiency worldwide and a leading cause of potential developmental disorders in children. Obesity seems to be associated with this condition, but it is still unclear if it is caused either by depleted iron stores, diminished availability, or both.Aim: To analyse the relationships between childhood obesity, iron metabolism and inflammation....

Recurrent Apnea in a Boy Suffering from Congenital Hyperinsulinism in the Course of Diazoxide Treatment

Nowaczyk Jedrzęj , Kucharska Anna

Congenital hyperinsulinism (CHI) is rare disease which prevalence is estimated as 1:2500 to 1:50000 born newborns. Main reason of the disease are genetic mutations in genes responsible for regulation of insulin secretion. First line treatment is diazoxide therapy.Our patient was diagnosed with CHI at the age of 2 months. Biochemical tests prooved diagnosis of CHI. He presented lack of negative feedback and secreted pathologic amount of insulin – dur...

TRIAC Treatment of Allan-Herndon-Dudley Syndrome (AHDS) due to Defects in Thyroid Hormone Transporter MCT8

Iglesias A , Gomez-Gila A L , Casano P , del Pozo J , de Mingo M C , Pons N , Calvo F , Obregon M J , Bernal J , Moreno J C

Background: AHDS is a devastating disease caused by defects in the thyroid hormone (TH) transporter MCT8. Endocrine expression is heralded by systemic hyperthyroidism with elevated serum T3, mildly increased TSH and decreased T4. However, the brain is hypothyroid, causing severe psychomotor retardation. Therapeutic attempts with PTU+levothyroxine or the T3-analogue DITPA could normalize TH derangements but without any neurological improvement. ...
