Introduction: Children with congenital adrenal hyperplasia (CAH) and adrenal insufficiency (AI) rely on lifelong hormone replacement with hydrocortisone (HC). Alkindi® is the first HC licensed for children from birth to 18 years with AI, available in small doses of 0.5, 1, 2 and 5mg required for the needs of neonates, infants and children.Objectives: Primary: long-term safety of Alkindi®; Secondary: long-term d...

Introduction: Classic congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency results in impaired synthesis of gluco- and often also of mineralocorticoids. Early treatment with glucocorticoids and mineralocorticoids prevents life-threatening crises. In some centres, additional salt is prescribed in the first year. However, until now the use of salt is controversial and not proved to result in better outcome in studies.<s...

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 ...

Context: There is a limited data from large cohorts regarding pubertal characteristics of children with classical 21-hydroxylase deficiency(21OHD).Objective: To explore the timing and tempo of puberty, and pubertal height gain(PHG) in children with 21OHD-CAH.Design: A multicenter observational, retrospective, longitudinal analysis.Patients: D...

Background: Androgens play a pivotal role in non-reproductive tissues, such as the kidney, heart, and liver, as well as the pancreas. Since the androgen receptor is expressed in pancreas and liver cells, this raises the possibility that excess testosterone results in insulin hypersecretion, and in fetuin-A, a protein produced in the liver. However, whether fetuin-A and insulin levels are affected by androgens in classic congenital adrenal hyperplasia (CAH) due...

Background: Paragnagliomas and pheochromocytomas are rare neuroendocrine tumors that originate from the paraganglionic cells of the autonomic nervous systems. These tumors may be extra or intra-adrenal in site. The use of antihypertensive medications is usually challenging in these patients. Long acting alpha and beta blockade can be quite useful preoperatively but challenging postoperatively. We present a case of familial paraganglioma that was successfully t...

Context: Deficiency of 3β-hydroxysteroid dehydrogenase 2 (3βHSD2) causes a very rare form of congenital adrenal hyperplasia (CAH) known as 3βHSD2 deficiency, which is a consequence of biallelic HSD3B2 gene defects. The estimated prevalence is less than 1/1,000,000 live births. Knowledge of comprehensive steroid metabolome patterns in 3βHSD2 deficiency is scarce.Objective: We aimed...

Background: Adrenarche describes the developmental event of the human adrenal cortex when the zona reticularis increases the synthesis of C19 steroids (DHEA/-S) markedly at around 6-8 years of age. Early appearance of this event is called premature adrenarche (PA) and has been associated with adverse outcomes including polycystic ovary syndrome and metabolic syndrome. Recently novel biosynthetic pathways of androgen production have been revealed, but their rol...

Objectives: To investigate changes in levels of autoantibodies(Abs) against 21-hydroxylase(21OH) in APECED patients and in patients with isolated primary autoimmune adrenal insufficiency (AI) over time after manifestation of AI.Methods: 24 patients with APECED with AI and 5 patients with isolated autoimmune AI were recruited. APECED was confirmed by finding at least two major components of the disease and/or two mutation...

Background: Glucagon stimulation test (GST) is used to assess growth hormone (GH) and cortisol reserves in children being investigated for GH deficiency, as a small percentage of children with idiopathic GH deficiency can also exhibit deficiency in the adrenocorticotrophic hormone (ACTH)-cortisol axis. However, the extent of normal cortisol response after glucagon stimulation and its associations with clinical and laboratory parameters have not been thoroughly...

Background: Congenital adrenal hyperplasia (CAH) is a rare condition characterised by adrenal insufficiency and a life-long risk of adrenal crises. There is a paucity of information on the epidemiology of acute adverse events in this population.Objective: To investigate the frequency, aetiology and consequences of acute adverse events attributed to adrenal insufficiency in CAH.Methods</stro...
