Background and aims: Congenital hyperinsulinism (CHI) is a rare condition causing severe and recurrent hypoglycaemia in children. Feeding is a key aspect of glucose delivery; however, with severe illness causing nausea and frequent use of parenteral and non-oral feeding, infants with CHI often develop a range of feeding problems. Previous studies have shown persistence of feeding problems in this group but there is limited data on families’ experiences and per...

Purpose: ACTH-independent bilateral adrenal hyperplasia is a rare cause of pediatric Cushing's syndrome (CS). Our objective was to describe the features of pediatric ACTH-independent CS and to compare groups defined by etiology.Methods: We conducted a retrospective observational study of patients aged 0–18 years at management in 1992–2022 for ACTH-independent CS in any of three Paris university pediatric...

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...

Introduction: Increlex® was approved as an orphan drug for treatment of growth failure in children and adolescents with SPIGFD in 2007 with relatively little data available. Therefore sequential measurements of serum IGFI, glucose, insulin and potassium were performed in SPIGFD patients treated with Increlex® to evaluate their significance in safety and efficacy.Design: Blood samples were taken after meals before and 30, 6...

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: 5α-reductase type 2 deficiency (SRD5A2) is a rare cause of 46,XY DSD. Consensus guidelines on sex of rearing assignment at birth favours male gender. Typically undervirilised genitalia at birth virilise variably at puberty, posing gender identity challenges.Aim: We describe relevant data on clinical phenotype, hormonal and molecular workup and gender preference in patients with SRD5A2 deficiency from a ...

Background: Severe primary insulin-growth factor-1 (IGF-1) deficiency (SPIGF1D) is a rare cause of growth retardation. Diagnostic criteria include age- and sex-dependent low basal IGF-1 levels (<2.5th percentile), height ≤ -3SDS, absence of growth hormone deficiency and of any secondary causes of growth failure.Objectives: Description of pubertal onset and growth spurt, data on adult or near-adult-he...

Background: Severe primary insulin-growth factor-1 (IGF1) deficiency (SPIGF1D) is a rare cause of growth retardation. Diagnostic criteria include age- and sex-dependent low basal IGF1 levels (<2.5th percentile), height ≤ −3SDS, absence of growth hormone (GH) deficiency and of any secondary causes of growth failure.Objectives: Phenotypic description, follow-up and molecular studies in a cohort of patients diagnosed with growth f...

Background: Glibenclamide has proven to be efficient for patients with neonatal diabetes owing to potassium channel mutations. Anyway its pharmaceutical form is not suitable for young children or infants. The tablets dosage is too high for most infants and must be crushed and diluted before administration. We developed a suspension of glibenclamide (EMA Orphean drug designation january 2016) fitting recommendations of drug administration to allow a precise dosage and designed ...

Background: Sulfonylurea therapy (SU) allows a better metabolic control than insulin in patients with neonatal diabetes secondary to mutation in potassium channel subunits (ND-K). Most of these patients have neurological and neuromotor developmental impairments whose changes under SU has not been studied in a systematic and prospective way in a large cohort.Objective and Hypotheses: To demonstrate the beneficial effect of SU on neuropsychological functio...
