21-hydroxylase deficiency (21OHD) is the most common form of congenital adrenal hyperplasia (CAH) and is caused by mutations in the CYP21A2 gene. 21OHD causes a wide array of clinical symptoms that result from gluco- and mineralocorticoid deficiency and adrenal androgen excess. In most cases, supra-physiological glucocorticoid doses are necessary which may cause short stature, obesity, hypertension, cardiovascular and metabolic co-morbidity with reduced quality of lif...

Background: Inherited amino-acid metabolism disorders (IAAMDs) require lifelong restriction of natural dietary proteins. Nutritional amino-acid mixtures (AMM) free of the poorly metabolised amino-acids by the enzyme block, improve nutrition. An adequate protein intake is crucial to ensure normal body development, notably during puberty. We aimed to: 1/ describe growth and puberty in IAAMDs 2/ investigate associations linking height, IGF1 and IGFBP3 with AAM an...

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...

Background: Although isolated GH deficiency (IGHD) is one of the most frequent causes of postnatal proportional undergrowth, up to 85–90% of IGHD cases are still classified as idiopathic. On the other hand, previous reports identified up to 40 different GH1 proximal promoter haplotypes, some of which show hypomorphic effects, significantly reducing GH1 expression levels.Objective and hypotheses: To investigate the frequency of ...

Background/ Aim: Over the past 6 years, the IGF1/ IGFBP3 generation test (IGFGT) has been used in Belgium in a standardized form to identify children with severe primary IGF1 deficiency (SPIGFD). In this study, the discordance of the IGF1 and IGFBP3 responses during an IGFGT and the prevalence of SPIGFD were analyzed in a cohort of children with short stature (height SDS < - 2) and presenting with low (below lower reference limit) serum IGF1 level and norma...
