Background: Implementation of type 1 diabetes (T1D) in children is constant from 20 years. In combination with insulin treatment, therapeutic patient education (TPE) is essential to improve care and prognostic. The use of video games as educational support appears suitable for learning in children, innovative, and interesting to respond to the increase in TPE needs in T1D and current economic constraints.Objective and hypotheses: To validate in a proof o...

Background: In adults, bariatric surgery has gradually emerged as a ‘metabolic’ surgery, able to rapidly improve metabolic disturbances linked to severe obesity. Even if type 2 diabetes is rare in european obese adolescents, alterations in insulin sensitivity are present in almost all.Objective and hypotheses: To evaluate the modification of insulin resistance (IR) and insulin sensitivity (IS) in severe obese adolescents who underwent bariatric...

Background: GH deficiency (GHD) is classically defined on the basis of a cut-off applied to the peak GH level during stimulation tests; a process with recognised limitations. Identifying the functional role of genes whose expression is associated with pGH may help with our understanding and classification of GHD.Objective and hypotheses: Identify patterns of gene expression (GE) related to pGH and to describe the function, and regulation of these genes.<...

Background: Prediction of response to recombinant GH (r-GH) is currently based on regression modelling. This approach generates a prediction equation which can be applied to data from an individual child. However this method can underestimate the effect of inter-dependent variables. Random forest classification (RFC) is an alternative prediction method based on decision trees that is not sensitive to the relationships between variables.Objective and hypo...

Background: Because the success rate of lifestyle interventions is modest in severely obese adolescents, surgical treatments are now proposed. Laparoscopic adjustable gastric banding (LAGB) represents an attractive treatment with minimal morbidity and reversible procedure.Method: All adolescents were included in prospective longitudinal assessment and entirely managed by a pediatric team. Surgery was proposed only after at least 1-year lifestyle interven...

Background: Acromegaly is a rare childhood disorder. The use of a growth hormone (GH) receptor antagonist, pegvisomant, has shown great results in adults with acromegaly. We describe results of pegvisomant therapy in two girls with invasive GH pituitary macroadenomas.Case presentation: Case 1: A somatotroph pituitary macroadenoma was diagnosed in a 8-year-old girl with progressive tall stature (height: 148 cm, >+3 S.D.; growth velocity...

Background: Prader-Willi syndrome is a rare genetic neurodevelopmental disorder caused by a paternal deficiency of maternally imprinted gene expression located in the chromosome 15q11-q13 region. Previous studies have demonstrated that several classes of neurodevelopmental disorders can be attributed to either over- or under-expression of specific genes that may lead to impairments in neuronal generation, differentiation, maturation and growth. Epigenetic chan...

Introduction: The neuropeptide oxytocin (OT) plays an important role in modulating behaviour and social interactions. Prader-Willi syndrome (PWS) is a rare genetic neurodevelopmental disorder due to abnormal hypothalamic development including OT dysfunction that involves endocrine, nutritional and behavioural outcomes/features/trajectory. We previously showed in a phase I/II study (NCT02205034) that 18 infants with PWS, less than 6 months of age, who received ...

Responsiveness to recombinant human growth hormone (rhGH) treatment in Turner syndrome (TS) is highly variable. Previous research has characterised genetic variants associated with rhGH response but these only have a minor impact. The relationship of these genetic variants to the blood transcriptome is unknown. The aim of this analysis was to relate unsupervised baseline blood transcriptome and genetic data from TS patients to their phenotype, karyotype and responsiveness to r...

Background/Aim: 25 to 40% of children with well-controlled X-linked hypophosphatemia (XLH) show linear growth failure, despite optimal conventional treatment (oral phosphate supplementation and active forms of vitamin D) with final height -2 SDS. Recombinant human growth hormone (rhGH) may be an adjuvant treatment of the growth retardation in these patients. Therefore, the main objective of this study was to describe how rhGH treatment improves final heigh...
