Background/Aim: X-linked hypophosphatemia (XLH) is a rare disease caused by inactivating mutations in the phosphate-regulating endopeptidase homolog X-linked (PHEX) gene, characterized by chronic hypophosphatemia. XLH children present with progressive skeletal deformities (leg bowing, waddling gait, poor growth and disproportional short stature), dental abscesses, and craniosynostosis. Most affected children have been treated so far with multiple dail...

Background: Protein intake is crucial for growth. Many inherited metabolic diseases (IMD) require a strict controlled protein diet.Aim: to evaluate growth, pubertal status and body composition in IMD requiring a strict controlled protein diet.Patients & Méthods: Longitudinal follow up cohort study. We recorded data before 4years (early childhood, n=189); betwe...

Background: Type1 diabetes mellitus is increasing worldwide in childhood. Education is an essential part of the package care at diagnosis. It adresses children with newly diagnosed type 1 diabetes and their families and is made by young doctors and paramedical staff (nurses and nutritionnists).Objective: to assess the knowledge of the medical and paramedical staff concerning the global management of type 1 diabetes in ch...

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: FOP is an ultra-rare, severely disabling genetic disorder characterised by progressive heterotopic ossification (HO) following flare-ups. The median age at diagnosis is 5 years, and patients are managed by multiple specialties. No study to date has provided a longitudinal evaluation of FOP. Final data are presented for participants, aged <25 years, enrolled in the first 36-month, prospective, global natural history study of FOP (NCT02322255).</...

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&Aim: Activation of mechanistic target of rapamycin (mTOR) as a major regulator of adipogenesis and lipid accumulation is controlled by upstream regulators hamartin/tuberous sclerosis complex (TSC) 1 and tuberin/TSC2. Hamartin and tuberin form a protein complex that inhibits signal transduction to mTOR. The impact of TSC1 deficiency is not clearly defined in human adipose tissue. We identified a likely pathogenic TSC1 splicing variant in a lipo...

Introduction: Non-communicable diseases are recognized as a major cause of morbidity in low and middle-income countries (LMICs). There are 21 francophone countries (>100 million speak French) in Sub-Saharan Africa (FSSA). We identified only 19 pediatric endocrinologists in FSSA (37% in Cameroon and Senegal) mostly trained in France or through the successful anglophone “Paediatric Endocrine Training Centers for (West) Africa” (PETC[W]A) offered i...

Background: Estrogen replacement is a treatment of choice for pubertal induction in adolescent girls with ovarian failure due to Turner syndrome (TS). Recently published data show, that prepubertal low dose estrogen replacement is more physiologic, and can optimize response to growth hormone treatment, pubertal timing, and improve cognition. The metabolic effects of such treatment regimen have not been fully investigated to date.Objective and hypotheses:...

Introduction: Non-alcoholic fatty liver disease (NAFLD) is diagnosed in up to 60% of overweight children. Diagnosis and management of NAFLD is challenging due to the lack of non-invasive imaging biomarkers. Ultrasound (US) is the most widely non-invasive method used to identify liver steatosis, however it has low sensitivity to detect mild steatosis and to quantify hepatic fibrosis. Liver Elastography (LE) is a non-invasive methodology used to evaluate hep...
