Context: Children with congenital adrenal hyperplasia (CAH) and adrenal insufficiency (AI) require hydrocortisone replacement from birth. Continuous monitoring of therapy during growth is necessary. Until now, children were dependent on off label use with divided hydrocortisone tablets or pharmacy compounded capsules. A licensed paediatric formulation that allows accurate dosing down to 0.5mg is now available.Objective: ...

Introduction: Lockdown measures following the COVID-19 pandemic are shown to have greatly affected lifestyle behaviours and health-related quality of life (HRQoL) of children. The impact on children with severe obesity has not yet been described. Aim of this study was to investigate the impact of COVID-19 lockdown on eating behaviours, physical activity (PA), screen time, and HRQoL of children (including adolescents) with severe obesity....

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...

Carney complex 1 (CNC, OMIM# 160980) is an autosomal-dominantly inherited complex tumor predisposition syndrome associated with skin pigment abnormalities and neoplasms of heart, endocrine glands and other organs. CNC is caused by heterozygous constitutional loss-of-function variants in the PRKAR1A-gene. PRKAR1A codes for the cAMP-dependent protein kinase type I-alpha regulatory subunit, an enzyme that represents an integral part of protein kinase A (PKA) tha...

Introduction: Children with cancer are at increased risk of endocrine complications, especially children with a brain tumor. One of these late effects includes bone disorders (ranging from low bone mineral density (BMD) to osteoporosis). Children with a suprasellar Low Grade Glioma (LGG) may be especially at risk for bone problems due to exposure to multiple treatment modalities, hypothalamic dysfunction and/or decreased mobility in combination with vision los...

Three patients from two unrelated families in Malta; one consanguineous (siblings: Patient 1, male and Patient 2, female) and one non-consanguineous (Patient 3, male), manifested hypogonadotropic hypogonadism with delayed puberty, intellectual disability, scoliosis, and ataxia with cerebellar hypoplasia on MRI. GnRH tests revealed low peak LH and FSH concentrations in the patients: Patient 1; LH 2.3 IU/L, FSH 4.4 IU/L (14.3y), Patient 2; LH 3.6 IU/L, FSH 6.4 IU/L (12.5y), Pati...
