Background: Recent studies demonstrate that children with Congenital Adrenal Hyperplasia (CAH) may develop visceral adiposity and insulin-resistance. Data on adipocytokines are scanty and contradictory.Objective: To evaluate leptin and adiponectin concentrations in CAH adolescents and investigate their correlation with glucocorticoids and hormonal and metabolic profile.Methods: Leptin, adiponectin, insulin and HOMA were evaluated i...

Background: Hypothalamic hamartomas(HH)-rare heterotopic congenital malformations (incidence 1:200 000)-present with central precocious puberty (CPP) or gelastic seizures (GS) but their natural history and best treatment strategy are unknown. Given their proximity to the hypothalamus–pituitary axis, wider endocrine dysfunction may be expected.Objective and hypotheses: To describe clinical features and any evolving endocrinopathies in HH patients, by...

Background: The effects of GH deficiency (GHD) and GH replacement therapy (GHRT) on body composition and functional measures of physical fitness are largely unknown particularly in children.Study aim: To evaluate body composition, muscular strength and flexibility, and exercise tolerance in GHD children at baseline and after one-year GHRT.Patients and methods: We enrolled 19 children and adolescents with untreated ...

Background: The melanocortin-4 receptor (MC4R) pathway is a key regulator of energy balance and satiety. Variants in genes upstream of MC4R encoding leptin receptor (LEPR), proopiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1(PCSK1) and those involved in Bardet-Biedl syndrome (BBS) can impair MC4R pathway signaling. Clinically, these variants are characterized by hyperphagia (Pathologic insatiable hunger) and early-onset, severe obesity. E...

Background: Bone involvement is described as a relevant sign in patients suffering Gaucher disease (GD).Objective and hypotheses: To analyze the long-term effect of enzyme replacement therapy on bone mineral density, a retrospective observational study was conducted in a cohort of 34 GD pediatric patients (14 males, 20 females, median age 11.3 years).Method: Lumbar spine (LS) (L2–L4, N: 34) and total body (TB) (N: 24) bone min...

Background: Numerous studies focused on the association between hypospadias and Endocrine Disrupting Chemicals (EDC) exposures. The wide variability of phenotypes included in these studies, the absence of comparison groups representative of the populations and the absence of concomitant genetic testing to rule out another cause make the results questionable.Objective and hypotheses: We performed a prospective phenotype-specific analysis of patients with ...

Background: Severe forms of 46,XY DSD with uncertain sex may have a family history (FH) in ~15–20% of cases. On the other side of the DSD spectrum, data regarding isolated hypospadias is sparse and a FH of genital malformation is thought to be less frequent.Objective and hypotheses: The aims of the study were i) to determine the frequency of genital abnormalities in families of isolated hypospadiac boys, ii) to determine whether there is a particula...

Background: Congenital Hypopituitarism (CH) is a rare heterogeneous genetic disorder characterized by the deficiency of pituitary hormones. CH can be associated with extra pituitary phenotypes such as midline craniofacial malformations. To date, a minority of patients carry pathogenic variants in more than 30 genes, and thus more than 80% of cases remain unresolved.Objective: To identify de novo pathogenic variants in no...

Purpose: The aim of this study was to identify risk factors for adult obesity in childhood solid cancer or lymphoma survivors (CCS).Patients and Methods: The study included 3199 patients of the French Childhood Cancer Survivor Study Cohort (FCCS) with 303 obese patients who had returned self-questionnaire. Analyses were adjusted on social deprivation index and sex.Results: CCS bein...

Congenital hyperinsulinism (CHI) is a life-threatening disease and manifests in the majority of cases in the first days after birth. Based on the distribution of affected cells, focal CHI forms are distinguished from diffuse CHI forms. Focal forms occur in most cases due to a paternally inherited heterozygous mutation in a subunit of an ATP sensitive potassium channel (ABCC8, KCNJ11). Within the diagnostic setting, focal forms can be visualized by 18F DOPA PET scan, as a marke...
