Hyperparathyroidism after three years of burosumab in children affected with x-linked hypophosphatemia

V Zhukouskaya Volha , Ertl Diana-Alexandra , Berkenou Jugurtha , Audrain Christelle , Bardet Claire , Rothenbuhler Anya , Linglart Agnes

Background/aim: Hyperparathyroidism (HPHT) is a common feature in patients with X-linked hypophosphatemia (XLH) especially when treated with vitamin D analogues and phosphate supplements. Although the exact mechanism is not clear, it is assumed that phosphate supplements taken chronically stimulate parathyroid hormone (PTH) secretion. We prospectively assessed the effect of a novel pathogenetic treatment anti-FGF23 (burosumab) on PTH levels in children with XL...

Exploration of O-link protein biomarkers in children born after IUGR and early impaired developmental changes in heart function

Änghagen Olov , Rudholm Feldreich Tobias , Ärnlöv Johan , Bang Peter

We recently assessed systolic heart function in children from IUGR and normal control pregnancies and reported early developmental impairment of left ventricular longitudinal strain – a sensitive echocardiographic measure – during the first 3 months of life in IUGR children. In accordance with previous studies, this suggest that the increased cardiovascular risk later in life imposed by IUGR/SGA may, at least to some extent, be primary and not entirely secondary to...

The Metabolism of 11-Oxy Androgens by Fetal CYP3A7 and CYP3A4 is Less Efficient Compared to Classical Androgens

du Toit Therina , E Flück Christa , V Pandey Amit , Groessl Michael

Steroidogenic enzyme expression in the fetal adrenal and the placenta hints at the production and metabolism of adrenal-derived 11-oxy androgens (11OxyAs) in the fetal-placental unit. Thus, 11OxyAs are present in placental tissue, fetal cord blood and neonatal serum, and could have a particular role during fetal development. The metabolism of the 11OxyAs in the fetal unit, therefore, presents as a focal point of investigation. Adrenal androgens are primarily metabolized by the...

Does the Treatment with Recombinant Human Growth Hormone Improve Final Height in Patients Affected by X-Linked Hypophosphatemia?

André Julia , Zhukouskaya Volha V. , Rothenbuhler Anya , Lambert Anne-Sophie , Salles Jean-Pierre , Mignot Brigitte , Linglart Agnès

Background/Aim: 25 to 40% of children with well-controlled X-linked hypophosphatemia (XLH) show linear growth failure, despite optimal conventional treatment (oral phosphate supplementation and active forms of vitamin D) with final height -2 SDS. Recombinant human growth hormone (rhGH) may be an adjuvant treatment of the growth retardation in these patients. Therefore, the main objective of this study was to describe how rhGH treatment improves final heigh...

Evaluation of Puberty in Patients with Noonan Syndrome and Mutations in the RAS/MAPK Genes

Malaquias Alexsandra C. , Noronha Renata M , Homma Thais K , Albuquerque Edoarda V A , Bertola Debora R , Jorge Alexander A L

Background: Noonan syndrome (NS) is a rare genetic disease characterized by facial dysmorphism, short stature, heart defects, chest deformities, and variable developmental delay/learning disabilities. Almost 80% of patients have a mutation in the genes encoding components of the RAS/MAPK pathway. Puberty was described as delayed in NS patients, but few studies are focusing on this subject and genotype-phenotype correlations so far.<s...

Criteria for First-Year Growth Response to Growth Hormone Treatment in Prepubertal Children with Growth Hormone Deficiency: Do they Predict Final Height Outcome?

Straetemans Saartje , De Schepper Jean , Thomas Muriel , Tenoutasse Sylvie , Beauloye Véronique , Rooman Raoul , BESPEED the members of

Background/Aim: Several criteria for the first year growth response (FYGR) to growth hormone (GH) treatment have been proposed. We explored which FYGR criteria predict best the final height outcome after GH treatment in prepubertal children with GH deficiency (GHD).Methods: Height data of 129 GHD children (83 boys) treated with GH for at least 4 consecutive years with at least 1 year before pubertal onset, were retrieved...

Brain Magnetic Resonance Imaging in Children with Isolated Growth Hormone Deficiency and Idiopathic Short Stature Diagnoses

Yesquen Pamela , Clemente María , Campos Ariadna , Mogas Eduard , Vázquez Élida , Carrascosa Antonio , Yeste Diego

Introduction: Diagnosis of growth hormone deficiency (GHD) and idiopathic short stature (ISS) is not straightforward. Nowadays growth hormone (GH) stimulation tests play a key role in the diagnosis but they are controversial due to the lack of normative data, poor reproducibility and poor disease concordance.The magnetic resonance imaging (MRI) is also a tool in the study of patients with short stature. Structural alterations of the hypo...

Background: 16 year old female neonate presented with neonatal diabetes, congenital hypothyroidism and sepsis.Objective and hypotheses: To evaluate the neonate for a common cause of neonatal diabetes, congenital hypothyroidism and sepsis and to explore for the best modality of management, including a possible role for sulphonylureas.Method: The neonate born of 3rd degree consanguinity was admitted and started on insulin infusion an...

Case Report on Hyperinsulinism/hyperammonaemia Syndrome: An Easily Treatable Cause of Postprandial Hypoglycaemia

Seneviratne Sumudu , Jayatunge Tharanga , Atapattu Navoda , De Silva K. S. H. , Wickramasinghe V. P. , De Silva Harendra

Background: Hyperinsulinism/hyperammonaemia (HI/HA) syndrome is associated with postprandial hypoglycaemia and mild hyperammonemia. There is increased insulin release following protein ingestion, which is amenable to diaxozide therapy. While developmental delay and normoglycaemic seizures can also occur, hepatomegaly has not been reported. We report a child with HI/HA and hepatomegaly, mild learning difficulty and obesity, who was initially mistaken to have glycogen storage di...

Background: Cystic fibrosis-related diabetes (CFRD) is a common complication in cystic fibrosis (CF). CFRD symptoms and treatment may impose additional burden and adversely affect their QoL.Objective and hypotheses: Assess HRQoL in CF children with normal glycaemia (CFN) and CFRD and evaluate the change in HRQoL over 1 year period along with clinical changes.Method: A prospective study was undertaken including children aged 10&#150...
