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...

Introduction: The ESPE e-Learning web portal is a free, globally accessible online tool to enhance learning in Paediatric Endocrinology and Diabetes. Since August 2022, the e-learning content includes 30 accredited hours of ESPE/ISPAD e-learning Continuing Medical Education (CME) courses with ten core modules each in Paediatric Endocrinology, Paediatric Endocrinology in Resource Limited Setting (RLS) and Paediatric Diabetes. The CME modules were created by wor...

Background: Late identification of male patients with congenital adrenal hyperplasia (CAH) due to 21 hydroxylase deficiency (21OHD) can increase the risk of developing a benign tumor near the mediastinum testes called testicular adrenal rest tumors (TART), that can cause infertility. However, these long-term consequences of 21OHD have not yet been studied in Indonesia.Objective: This study aims to elucidate the prevalenc...

The phenotype in male individuals with a mosaic sex chromosomal abnormality is heterogenous, but ambiguous genitalia, delayed puberty, disturbed spermatogenesis, and short stature are frequently seen. Genetic investigation in boys with idiopathic/isolated short stature usually includes SHOX gene analysis (sequencing and copy number detection by MLPA), genome wide array analysis, and/or whole exome sequencing (WES). In the Netherlands, conventional karyotyping is not part of th...

Introduction: Cardiovascular disease (CVD) is the major cause of morbidity and mortality in type 1 diabetes (T1D). Recent studies implicated deregulated phosphate homeostasis in the etiology of CVD. The objective of this study is to address the relationship between the phosphate-regulating hormone fibroblast growth factor 23 (FGF23) and cardiovascular risk factors in adults with and without type 1 diabetes (T1D).Methods:...

Introduction: Individuals with Prader-Willi syndrome (PWS) suffer from hyperphagia, hypotonia and hypothalamic dysfunction, leading to a variety of pituitary hormone deficiencies. Central adrenal insufficiency (CAI) has been reported in PWS, while each of these studies used different testing modalities and cut-off values. Therefore, reported prevalence of CAI ranges from 0% to 60%. It has been speculated that CAI might be responsible, at least in part,...

Introduction: Turner syndrome (TS) is a genetic condition which is reported to be associated with electrocardiogram (ECG) abnormalities, of which the rate-corrected QT interval (QTc) is the most common indicated deviation. Our objectives were to gain more insight in the prevalence of QTc-prolongation using both Bazett's and Hodge's correction formulas in patients with TS of all ages and to investigate whether QTc prolongation is more prevalent in patie...

Introduction: Hypophosphatasia (HPP) is a congenital disorder of the bone and mineral metabolism. It is based on mutations in the ALPL gene, which codes for tissue-unspecific alkaline phosphatase (TNSAP). Methods:The casuistic of 3 children with heterozygous ALPL mutation are presented. The patients were identified by laboratory data screening for reduced AP activity at the Children's Hospital of the University Hospital Freiburg....

Introduction: The hypothalamic melanocortin-4 receptor (MC4R) pathway plays a vital role in energy balance. Genetic defects in the MC4R pathway may result in severe early onset obesity.Objective: The TEMPO registry (NCT03479437) aims to identify and enroll approximately 1000 participants with rare genetic forms of obesity that are potentially related to key genes, upstream or downstream, of the MC4R. In addition, the TEMPO registry will evaluate the burd...

Background: POMC deficiency is an extremely rare monogenetic obesity syndrome generally characterized by early onset hyperphagia, red hair and adrenal insufficiency. So far treatment of obesity and hyperphagia with MSH substitution failed, either due to ineffectiveness or side effects of available MC4R agonists.Objective and hypotheses: We hypothesized that the new MC-4R agonist setmelanotide might be a treatment option in POMC deficient patients.<p ...
