Background: The steroidogenic enzyme aromatase (CYP19A1) is a protein located in endoplasmic reticulum (ER) that catalyzes the conversion of androgens to estrogens. Both deficiency and excess of aromatase activity lead to disease states implicating its role in human biology. Cytochrome P450 (CYP) enzymes in ER use reduced nicotinamide adenine dinucleotide phosphate through cytochrome P450 oxidoreductase (POR) for their metabolic activities. Mutations in POR cause disorders of ...

Background: It is well known that growth hormone (GH) brings about several effects, involving bone, body composition, lipids and glucose homeostasis. However, the complex interplay between these parameters is rather poorly studied in children with childhood-onset-GH deficiency (CO-GHD).Objective and hypotheses: To investigate lipids, adipokines (leptin- adiponectin- resistin) and glucose homeostasis and their relationship with bone and body composition i...

Background: GH treatment is effective in improving adult height (AH) in short children born Small for Gestational Age. If SGA children are short at the start of puberty, they could benefit from combined GH/GnRH Analogue (GnRHa) treatment.Objective and hypotheses: To determine the timing and progression of pubertal development in short SGA children, comparing GH treatment with combined GH/GnRHa treatment.Method: For the present stud...

Background: A broad spectrum of human diseases including abnormalities in steroidogenesis is caused by mutations in the NADPH P450 oxidoreductase (POR). POR transfers electrons from NADPH to several small molecules, non-P450 redox partners and all microsomal cytochrome P450 proteins. POR disruption affects all partners with disastrous consequences and POR knock-out mice are embryonically lethal. A number of POR mutations and polymorphisms have been characterized from patients ...

Background: Severe obesity due to hypothalamic involvement has major impact on prognosis in long-term survivors of childhood-onset craniopharyngioma. The long-term effects of rehabilitation efforts on weight development and obesity in these patients are not analysed up to now.Method: 108 patients with childhood-onset craniopharyngioma recruited in HIT Endo before 2001 were included in the study. Long-term weight development (BMI SDS after ...

Background: As a result of hypothalamic involvement and/or treatment-related hypothalamic damage, up to 75% of childhood craniopharyngioma patients develop hypothalamic obesity.outcome is important for optimization of treatment.Method: Eating behaviour was analysed in 101 survivors of childhood craniopharyngioma, recruited from 1980 to 2001 in the HIT-Endo multicentre study, and in 85 BMI-matched healthy controls using the Inventory for eating behavior a...

Background: Anti-Müllerian hormone (AMH) inhibits the in utero growth of the Müllerian structures in female fetuses. In neonates with suspected disorders of sexual development (DSDs), the presence of testicular tissues and functioning Sertoli cells can be investigated by testing for serum AMH concentration.Objective: To evaluate the performance of two new AMH assays in a hospital laboratory.Method: The technical performan...

Background: Adrenal insufficiency is a rare cause of neonatal cholestasis, which is reversible with prompt glucocorticoid administration.Case presentation: A 2-month old baby boy was referred to the paediatric endocrine department for evaluation of intermittent hypoglycaemia associated with metabolic acidosis, hyponatraemia and hyperkalaemia. The infant was second born to second-degree consanguineous parents whose first...

Introduction: Continuous Glucose Monitoring Systems(CGM), including real-time(rtCGM) or intermittently Ssanned CGM(isCGM, flash technology) are evolving technologies that can help both healthcare professionals and families to improve glycaemic control in children and adolescents with diabetes mellitus. The technology offers the possibility of monitoring glucose in real time or on demand through the interstitial fluid, contributing to the improvement of glycaem...

Introduction: Carbohydrate restriction (CH-R) in adolescents with obesity results in faster BMI reduction and glucose metabolism improvement than diets with normal carbohydrate proportion, without a higher weight regain in the short term. However, data on weight and metabolic trajectories of these patients after a more prolonged follow-up are sparse.Objectives: To evaluate metabolic and body composition evolution during ...
