Background: Pfizer International Growth Database (KIGS) contains data of Turner syndrome (TS; N=7378) or Noonan syndrome (NS; N=613, female=224; male=389) patients who were treated with rhGH.Objective: To compare the effect of rhGH on near adult height (NAH) in TS and NS patients. We hypothesized a similar outcome in both diagnoses. Determinants of the treatment outcome in NS patients were also assessed.Patients a...

Background and aims. In several European countries, the incidence of primary congenital hypothyroidism (PCH) seems to increase in the last decade, especially in countries that have lowered the newborn screening TSH cutoff. In Flanders, two centers manage since 2012 the newborn screening for PCH and these maintained the same TSH assay (Delphia, Perkin Elmer) and cutoff (15 mU/l). We studied the current incidence and etiology of PCH and initiation of thyroxine treatment in Fland...

Congenital Hyperinsulinism (CHI) is primarily associated with defects in the regulated release of insulin from ß-cells but little information is available about the role of other islet cell types. Pancreatic polypeptide (PP) cells represent a minor component of the islet endocrine cell population. PP causes satiety, decreases gastrointestinal tract motility and suppresses glucagon release. Since CHI is associated with feeding problems and loss of glucagon-mediated counter...

Background and Aim: Several genetic variants associating with hepatic fat content in adults have been identified in genome-wide association studies. Their effects in children remain unclear. This study aimed to test the effect of genetic variants known to associate with hepatic fat in adults, individually and combined as a genetic risk score (GRS), on cardiometabolic traits, and to investigate the predictive ability of the GRS for hepatic steatosis in children...

Background: Congenital adrenal hyperplasia (CAH) arises from mutations in CYP21A2 gene, which encodes for the steroidogenic enzyme 21-hydroxylase. Currently employed chorionic villus sampling and amniocentesis provide genetic results at ~14 weeks of gestation at the earliest. At this time, the genitalia of the affected female foetuses have already become virilized. To prevent genital ambiguity, prenatal treatment with dexamethasone must begin on or before gestational ...

Adeno-associated virus (AAV) gene therapy reached the maturity and a liver-targeting approach is currently used as a replacement treatment for rare hepatic and muscular diseases. X-linked hypophosphatemia (XLH) is a rare disease associated with hyperfunction of fibroblast growth factor 23 (FGF23) in bone and characterized by severe skeletal deformities and short stature. The current medical therapies for XLH requires life-long repeated treatment presenting major limitatio...

Background: Hypogonadism has been associated with cardiovascular disease. However, little is known about the cardiovascular impact of hypogonadism during development. Using hypospadias as a surrogate of hypogonadism, we investigated whether hypospadias is associated with vascular dysfunction during childhood and whether it is a risk factor for adult cardiovascular disease.Methods: Our human study spanned molecular mechan...

Background: Brain tumours are the most frequent solid tumours during childhood. Many of these patients develop endocrine disorders.Objective: To describe our cohort of patients with primary brain tumours, followed in the Pediatric Endocrinology Unit at Hôpital Universitaire Necker–Enfants Malades, Paris, France between 2010–2015, to assess current practice and propose recommendations.Methods: Retrospective a...

Introduction: Primary brain tumors are the second most common childhood malignancies, with an increasing survival rate over the years. Late effects on puberty and fertility alter survivors’ quality of life.Methods: We included 204 patients diagnosed with a primary brain tumor before 18 years, followed in pediatric endocrinology at the University Hospital “Necker-Enfants Malades” in Paris between January 20...

Aldosterone synthase deficiency (ASD) is a rare autosomal recessive disease caused by inactivating mutation in the CYP11B2 gene, usually presenting with severe salt-wasting in infancy or stress-induced hyperkalaemia and postural hypotension in adulthood. ASD is unable to be detected by Neonatal screening of 17-hydroxyprogesterone, hence patients would not be diagnosed until they suffer from salt-wasting crisis. Due to this potentially life-threatening risk, early detection and...
