Introduction: The gold standard for the diagnosis of adrenal insufficiency (AI) is the ACTH stimulation test. According to the guidelines approved by the European Endocrine Society, the ACTH stimulation test should be performed with the administration of the standard dose of i.v. Synachten® 250 µg for adults and children aged ≥ 2 years (infants should receive 15 µg/kg, children ≤ 2 years 125 µg). In many clinical settings a Syna...

Background and aims: Poly- and perfluoroalkyl substances (PFAS) are non-degradable, man-made-chemicals. PFAS are considered to be ‘Endocrine Disrupting Chemicals’ (EDCs), a group of chemicals which have been reported to interfere with endocrine processes and cause adverse effects on perinatal, neurodevelopmental, metabolic and reproductive outcomes. Especially when exposure occurs during susceptible periods of human development, such as early life....

Introduction: Recombinant Growth Hormone (GH) has changed the lives of many patients with Prader-Willi Syndrome (PWS). GH treatment has beneficial effects on body composition, physical performance, cognition, psychomotor development, respiratory function and quality of life of patients with PWS. Due to the narrow therapeutic range, GH treatment is subject to strict limits. Clinicians measure serum immunoreactive Insulin-like Growth Factor 1 ('total IGF-I&#...

Background & Aims: Children with acute lymphoblastic leukemia (ALL) frequently receive high doses dexamethasone during treatment, which may induce acute side effects. The aims of the current study were to determine the influence of a five-day dexamethasone course on changes in leptin, fat mass, body mass index (BMI), hunger, sleep and fatigue and to explore the associations between these changes.Methods: Pediatric AL...

Objective: This project aims to evaluate the effect of two isotopically labelled internal standards on the quantification of 17OHP by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS) as an orthogonal technique.Methods: Three LC-MS/MS and one GC-MS/MS laboratories, spanning four countries worldwide, who routinely measure serum17OHP, compared two internal ...
