Gene-Environment (GxE) Interactions in Childhood Type 1 Diabetes (T1D): A Case-only Geographical Approach in the ISIS-Diab Cohort

Bougneres Pierre , Fur Sophie Le , Valtat Sophie , Lathrop Mark , Valleron Alain-Jacques , ISIS-Diab Network France

Background: T1D concordance in MZ twins being ~40%, non-heritable factors play a major causal role in this autoimmune disease. T1D has recently increased in young European children. Collecting prospective environmental data in a cohort of millions children-years starting soon after birth seems unpracticable. Retrospective case–control studies are an alternative, provided biased controls and recall bias can both be avoided.Objectives: To develop a &#...

Childhood Type 1 Diabetes (T1D) Management with e-learning through Self-educational Tools

Bibal Cecile , Laure Castell Anne , Aboumrad Brigitte , Lucchini Philippe , Bougneres Pierre

Background: Children with type 1 diabetes (T1D) and their parents need personalized i) information about the disease and glucose homeostasis and ii) knowledge and guidelines about diet and insulin therapy.Objectives: To set a complete educational program that allows children with T1D to improve disease management and daily life.Methods: Education modules were written and trained with children and parents at outpatient visits. Each ...

Laparoscopic sleeve gastrectomy in adolescents with morbid and dynamic obesity. A controlled monocentric study.

Filippo Gianpaolo De , Pourcher Guillaume , Castell Anne Laure , Kyheng Christele , Bougneres Pierre

Background: Following years of dietary and lifestyle intervention (DLI) as the only therapeutic option, reports of bariatric surgery are emerging in adolescents with morbid obesity. We present herein preliminary results of our 4-yr sleeve gastrectomy study.Objectives and hypotheses: To compare the effects of laparoscopic sleeve gastrectomy (LSG) and intensive DLI in adolescents with morbid obesity (ie BMI >4 DS) and extremely active weight gain (i.e....

“Semi-Hot” Thyroid Nodules Associated with GNAS Mutations in Three Adolescents

Lambert Anne Sophie , Rodrigue Danielle , Papin Jean Francois , Linglart Agnes , Bougneres Pierre

Background: Hot thyroid nodules are uncommon in children and adolescents. Hyperfunctioning adenoma do not always produce hyperthyroidism, but can precede the apparition of a truly toxic adenoma. Autonomous adenoma can be associated with mutations of TSH-R and some mutations of GNAS.Patients: Patient 1 presented mild clinical hyperthyroidism. Patients 2 and 3 were asymptomatic and had clinical euthyroidism. Examination revealed a unique isolated thyroid n...

Lack of Catch Up Growth in Severe Hashimoto Thyroiditis (HT) in Young Children

Vincent Audrey , Rodrigue Danielle , Teinturier Cecile , Bouvattier Claire , Bougneres Pierre , Linglart Agnes

Background: Profound hypothyroidism due to Hashimoto thyroiditis (HT) is a cause of severe growth arrest in children. Although it is commonly thought that thyroxine replacement fully restores height deficit, no data on catch up growth are available.Objective and hypotheses: Assess the growth pattern and final height in a series of 10 patients with severe HT afec L-thyroxine therapy was initiated.Method: Monocentric retrospective ob...

Validating Genetic Markers of Response to Recombinant Human GH in Children with GH Deficiency or Turner Syndrome: Results From the PREDICT Validation Study

Chatelain Pierre , Stevens Adam , De Leonibus Chiara , Clayton Peter , Wojcik Jerome

Introduction: Genetic markers associated with the response to recombinant human GH (r-hGH) have been identified in Growth Hormone Deficiency (GHD) and Turner Syndrome (TS) children in the PREDICT long-term follow-up (LTFU) prospective study (NCT00699855).1 A validation (VAL) study (NCT01419249) was conducted to confirm association.Methods/design: Inclusion criteria for GHD and TS children were identical in the LTFU and VAL studies (GHD defined...

Short-Term Results of Single-Port Sleeve Gastrectomy in Adolescents with Severe Obesity

De Filippo Gianpaolo , Pourcher Guillaume , Piquard Catherine , Ferretti Stefano , Dagher Ibrahim , Bougneres Pierre

Background: Dietary and lifestyle modifications commonly proposed to overweight or obese youth lack efficacy in those with severe obesity. Early results with bariatric procedures in obese adolescents suggest that weight loss and safety are comparable or better than those seen in adults. One of these procedures, laparoscopic sleeve gastrectomy, is commonly performed using multiple ports. We selected single port sleeve gastrectomy (SPSG) as a minimally invasive surgery to be tes...

Normal Minipuberty in a Patient with DAX1 Mutation: a Reliable Marker of the Function of the Hypothalamic–Pituitary–Gonadal Axis?

Fudvoye Julie , Christine Lebrethon Marie , Pierre Bourguignon Jean , Simone Parent Anne

Background: We report here the case of a 5-week-old male patient, referred to the hospital because of failure to thrive. An adrenal insufficiency was diagnosed and the genetic testing showed a mutation in the DAX1 gene leading to a premature stop codon.In addition to adrenal hypoplasia congenita, DAX1 mutation is known to be classically associated with hypogonadotrophic hypogonadism which is mostly characterized by absence of onset of puberty and inferti...

Long Term Outcomes of Precocious Puberty due to Hypothalamic Hamartomas

Rodrigue Danielle , Thomas-Teinturier Cecile , Motte-Signoret Emmanuelle , Bougneres Pierre , Linglart Agnes

Background: Hypothamamic hamartomas (HH) are rare benign tumours of the tuber cinereum revealed by central precocious puberty (CPP) and, in some cases, gelastic seizures and cognitive impairment.Objective and hypotheses: Evaluation of the treament by GnRH analogues on control of puberty and final height in patients with HH.Method: We report a series of five cases of CPP secondary to HH (four girls and one boy). Early in infancy (9 ...

Genetic Markers Contribute to the PREDICTION of Response to GH in Severe but not Mild GH Deficiency

Stevens Adam , Murray Philip , Wojcik Jerome , Raelson John , Koledova Ekaterina , Chatelain Pierre , Clayton Peter

Background: Single nucleotide polymorphisms (SNPs) associated with the response to GH therapy have previously been identified in growth hormone deficient (GHD) children in the PREDICT long-term follow-up (LTFU) study (NCT00699855).Objective and hypotheses: To assess the effect of GHD severity on the predictive value of genetic markers of growth response.Method: We used pre-pubertal GHD children (peak GH <10 μg/l) from the ...
