Mast cells are known to control mineralocorticoid synthesis and secretion in human normal adrenal gland and aldosterone-producing adenomas through release of serotonin. We recently detected these immune cells in human fetal adrenal from 18 weeks of gestation in the subcapsular layer, in correlation with the expression of steroidogenic enzymes required for aldosterone biosynthesis. This observation suggests the implication of mast cells in the mineralocorticoid synthesizing pat...

Background: Development of cystic fibrosis–related diabetes (CFRD) is associated with worse pulmonary function, poorer nutritional status, more chest infections and increased mortality. In cystic fibrosis (CF) patients, abnormality of the 1 hour glucose during Glucose Tolerance test (GTT) is reported to be a better predictor of early CFRD and is associated with decline in pulmonary function compared to the 2-hour glucose level during GTT. We report a case series of 4 pati...

Background: We describe our experience in medical therapy for invasive somatotroph pituitary macroadenomas in 8 children or adolescents presenting with acromegaly/gigantism, in terms of growth and IGF-I levels control.Patients: Eight children, aged 5 to 17 years (median 12.4 years), presented with growth hormone (GH) hypersecretion related to somatotroph pituitary macroadenomas with cavernous sinus invasion in 6/8. Genetic testing revealed AIP mutation i...

Background: Congenital hypothyroidism (CH) is referred to dyshormonogenesis for 15 to 30%. Homozygous mutations associated have been demonstrated in DUOX2, TPO, TG, SLC5A5 (NIS), SLC26A4 (Pendred), DUOXA2, and IYD (DEHAL1) genes.Objective and hypotheses: Previous studies focusing on one or few thyroid-specific genes have proved not to be comprehensive enough for understanding physiopathological mechanisms of HC with dyshormonogenesis. Emerging diagnostic...

Background: TransCon Growth Hormone is a once-weekly sustained-release prodrug of recombinant human growth hormone (hGH, somatropin). Based on the inert TransCon prodrug technology unmodified hGH is released with a Cmax and AUC comparable to daily therapy. TransCon hGH leverages the known pharmacology of daily hGH and is being developed for the treatment of growth hormone deficiency (GHD).Objective and hypotheses: Both hGH levels and resulting IGF-I leve...

Background: Knowing the changes of cardiovascular risk factors (CRF) in relation to weight loss would be helpful to advise overweight children and their parents and to decide whether drugs should be prescribed in addition to lifestyle intervention.Objective and hypotheses: The aim of the study was to determine the degree of overweight reduction to improve CRFs in overweight children.Method: We studied changes of blood pressure (BP)...

Background: Bi-allelic mutations of CYP21A2 encoding 21-hydroxylase are the most frequent cause of congenital adrenal hyperplasia (CAH). Non-classical CAH (NCCAH) or even just hyperandrogenism may be caused by mild or mono-allelic (single) heterozygous mutations of CYP21A2. These mutations are associated either with elevated basal or ACTH-stimulated levels of 17-hydroxyprogesterone (17OHP) in blood.Objective and hypotheses: The objective of this study wa...

Background: In premature and small-for-date infants, immature adrenal enzyme activity, adrenal stress responses and impaired hepatic clearance may lead to mild to moderate false-positive increases of steroid hormone precursors. This complicates screening programs for congenital adrenal hyperplasia (CAH) in these patients.Objective and hypotheses: We present a preterm female infant (born at 33 weeks of gestation) who’s newborn screening 55 h after bi...

Background: Various endocrine complications are common after HSCT but primary adrenal insufficiency (Addison’s disease, AD) is absolutely rare. To the best of our knowledge, there is only one case of AD reported in a 9-year-old girl after HSCT and busulfan and cyclophosaphamide-based conditioning for myelodysplastic syndrome.Objective: We report on a 14-year-old boy from Albania who developed an Addisonian crisis 12.7 years after HSCT.<p class="...

Background: Congenital hyperinsulinism of infancy (CHI) is the most common cause for persisting hypoglycaemia in infancy. Genetic causes are mutations in ABCC8 or KCNJ11 (coding for K+ATP-channel subunits), less frequently mutations in GCK or GLUD1. Further genetic examinations are usually performed only if phenotypic aspects point to other specific genes, such as the rare short chain 3-hydroxylacyl-CoA dehydrogenase (<...
