The Growth Response to Growth Hormone Treatment is Greater in Patients with SHOX Enhancer Deletions Compared to SHOX Defects

Donze Stephany , Meijer Caroline , Kant Sarina , Zandwijken Gladys , van der Hout Annemieke , van Spaendonk Resie , van den Ouweland Ans , Wit Jan Maarten , Losekoot Monique , Oostdijk Wilma

Background: Short stature caused by point mutations or deletions of the short stature homeobox (SHOX) gene (SHOX haploinsufficiency, SHI) is a registered indication for growth hormone (GH) treatment. Patients with a SHOX enhancer deletion (SED) have a similar phenotype, but their response to GH is unknown. It is uncertain if duplications of SHOX or its enhancer (SDUP) can cause short stature.Objective and hypotheses: To describe the clinical characterist...

Resting energy expenditure and body composition in children and adolescents with severe obesity due to (suspected) medical causes: comparison between different subtypes of obesity

Abawi Ozair , Koster Emma , Welling Mila , Boeters Sanne , van Rossum Elisabeth , van der Voorn Bibian , de Groot Cornelis , van den Akker Erica ,

Background: Paediatric obesity is a multifactorial disease characterized by an imbalance between energy intake and expenditure. In rare cases, obesity is caused by underlying medical disorders arising from disruptions in the leptin-melanocortin pathway, which regulates satiety and energy expenditure.Aim: To investigate resting energy expenditure (REE) in relation to body composition in children and adolescents with sever...

Clinical features and response to rhGH treatment in ten patients with heterozygous IGF1 variants

Punt Lauren , van der Kaay Danielle , van Setten Petra , Bocco Gianni , de Munnik Sonja , Losekoot Monique , van Duyvenvoorde Hermine , de Bruin Christiaan , Maarten Wit Jan , Joustra Sjoerd

Introduction: Patients carrying homozygous IGF1 loss-of-function mutations are extremely rare and show severe pre- and postnatal growth failure, microcephaly, developmental delay, retrognathia and sensorineural deafness. Heterozygous variants in IGF1 appear to be more common in short stature, but only few cases have been reported in detail. Therefore, clinical features and growth response to recombinant human growth hormone (rhGH) therapy are...

Metabolic Health in Short Children Born Small for Gestational Age Treated with GH and GnRHa: Results of a Randomised, Dose-response Trial

Background: Previously we showed that pubertal children born small for gestational age (SGA) with a poor adult height (AH) expectation can benefit from treatment with GH 1 mg/m2 per day (~0.033 mg/kg per day) in combination with 2 years of GnRH analogue (GnRHa) and even more so with a double GH dose. GnRHa treatment is thought to have negative effects on body composition and blood pressure. Long-term effects and GH-dose effects on metabolic health in children treate...

Recurrent Ketosis after Prolonged Exercise in Type 1 Diabetes: The Need for Glycogen Replacement Strategies: Case Report

van Albada Mirjam , van Waarde Willie Bakker

Background: In diabetic athletes, glycogen depletion can contribute to the early development of starvation ketones as is demonstrated by our patient.Case presentation: Our patient, a 15-year-old male triathlete with type 1 diabetes for 5 years was referred to our tertiary center because of suboptimal regulation on continuous subcutaneous insulin infusion (CSII). He frequently awoke with nausea and ketosis, which was initially attributed to failure of ins...

Capillary TSH Cut-off Levels for Congenital Hypothyroidism Screening: Evidence Against Adopting the UK Threshold of 10 mIU/l

Jones Jeremy , Shaikh Guftar , Mason Avril

Background: The recommended capillary TSH cut-off level for neonatal screening for congenital hypothyroidism (CH) in the UK is 10 mIU/l. However several of the regional screening laboratories have adopted lower cut-off limits in order to increase detection sensitivity. There is now pressure to standardise the UK screening programme with universal adoption of the recommended cut-off. Scotland has been using a cut-off of 8 mIU/l since the adoption of AutoDELFIA TSH screening met...

Sexual Dimorphism in Cortisol Production and Metabolism Throughout Pubertal Development: A Longitudinal Study

van Keulen Britt , Dolan Conor , van der Voorn Bibian , Andrew Ruth , Walker Brian , Boomsma Dorret , Hulshoff-Pol Hilleke , Rotteveel Joost , Finken Martijn

Background: Sex differences in disease susceptibility might be explained by a sexual dimorphism in hypothalamic-pituitary-adrenal axis activity, which has been postulated to emerge during puberty. The aim of this study is to assess the contribution of pubertal development to sexual dimorphism in cortisol production and metabolism.Methods: Participants, born between 1995 and 1996, were enrolled from the population-based N...

International Consensus: Ovarian Tissue Cryopreservation in Young Turner Syndrome Patients. Outcomes of an Ethical Delphi Study Including 55 Experts from 16 Different Countries.

Summary Answer: The majority of the expert panel states that ovarian tissue cryopreservation (OTC)should be offered to young females with Turner syndrome (TS)Background: OTC is a valid option to preserve the fertility of young females at risk of iatrogenic premature ovarian insufficiency (POI). Offering OTC to females with a genetic cause of POI seems a logical next step. One of the most common genetic disorders related ...

Effects of tiratricol treatment withdrawal in MCT8 deficiency: ReTRIACt Trial

Freund Matthijs , Chatterjee Krishna , van Geest Ferdy , van der Most Floor , Bowers Dominic , Persson Anders , J Bauer Andrew , Edward Visser W.

We introduce the ReTRIACt Trial (NCT05579327) of tiratricol (Triac) for MCT8-deficiency, a rare X-linked disease resulting from disordered thyroid hormone transport and characterized by profound neurodevelopmental delay and features of chronic peripheral thyrotoxicosis. The ReTRIACt Trial aims to verify the effects of tiratricol observed in previous studies. It is a double-blind, randomized, multicenter, placebo-controlled study to evaluate the effects of tiratricol discontinu...
