Background: Adherence to GH treatment is a challenge.Objective and hypotheses: We analysed the impact of treatment duration, treatment success, treatment indication, age, gender, pubertal stage, and height on treatment adherence (TA) to optimise treatment success.Method: Based on the easypod autoinjector used in the Saizen-online prospective, multicenter, open-label, noninterventional study we analyzed TA in 6 months periods. TA wa...

Background/Objective: 17bHSD3D is a rare genetic disorder that leads to disorders of sex development (DSD) in 46,XY patients. Phenotype at birth ranges from unsuspicious female genitalia to micropenises. Besides molecular genetic testing no reliable lab parameters have been established for pre-identifying patients through basal steroid-levels or hCG-testing. This bares the risk of under-, mis- or late diagnosis. Further, little research has been performed on psychological well...

Background: Beckwith Wiedemann syndrome (BWS) is an overgrowth disorder with vari-able phenotype (hemihypertrophy, macroglossia, visceromegaly, malformations, and hypo-glycaemia in 30–50%) and predisposition for tumors, during the second part of pregnancy and first few years of life.Objective and hypotheses: Molecular characterisation of a patient with BWS was perfor-med to ensure adequate clinical management. This analysis revealed the most common ...

Background: Steroidogenic factor (SF1, NR5A2) regulates multiple genes known to be involved in gonadal development, adrenal development, steroidogenesis, and gonadotroph development. Heterozygous mutations in the NR5A1 gene have been described in association with mild to severe gonadal dysgenesis with or without adrenal failure. Homozygous mutations are rare and have also been described in association with gonadal dysgenesis with or without adrenal failure.<p class="abstex...

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 (<...

Background: Reports on obesity, high blood pressure and reduced insulin sensitivity in children with classical congenital adrenal hyperplasia (CAH) indicate an increased cardiovascular risk.Objective and Hypotheses: To evaluate potential mechanisms, we analysed various parameters of the carbohydrate metabolism in children and adolescents with CAH.Method: Out of 86 patients with classical CAH, n=41 (21 m, 20 f; ages: 6.9&#1...

Background: It has been reported that children with congenital adrenal hyperplasia (CAH) have higher BMI, increased body fat and greater waist-to-hip ratio (WHR) than control children.Objective and hypotheses: Recently it was speculated that the screening potential of waist-to-height ratio (WHtR) and waist circumference (WC) for cardio-metabolic risk in adults is higher than WHR and BMI.Method: To review this hypothesis, we studied...

Background: Implementation of type 1 diabetes (T1D) in children is constant from 20 years. In combination with insulin treatment, therapeutic patient education (TPE) is essential to improve care and prognostic. The use of video games as educational support appears suitable for learning in children, innovative, and interesting to respond to the increase in TPE needs in T1D and current economic constraints.Objective and hypotheses: To validate in a proof o...

Background: Patients with 21-Hydroxylase deficiency (21OHD) present increased levels of cytochrome P450 21-hydroxylase substrates, like progesterone and 17α-hydroxyprogesterone. Previous studies could show that these hormones are involved in the production of androgens via the backdoor pathway. As a second source of androgens, 11-oxyandrogens derived from the human adrenal glands are recognized as being major androgens. Specifically, 11-oxyandrogens ...

Introduction: Androgens are essential for the development of male sex characteristics. Testosterone (T) production from androstenedione (A) by the Hydroxysteroid 17-Beta Dehydrogenase 3 (HSD17B3) in gonadal Leydig cells triggers the differentiation of the Wolffian ducts into epididymis, vas deferens, seminal vesicles and the prostate. Shortly after, the virilisation of the external male genitalia starts through the conversion of T into dihydrotestosterone (DHT...
