CG at the Methylation IGF1 Locus is an Epigenetic Predictor of GH Sensitivity

Ouni Myriam , Castell Anne Laure , Bougneres Pierre

Background: The growth and IGF1 responses to GH treatment show a large variation across children with idiopathic short stature (ISS). Compliance and GH regimens are important determinants. The d3 variant of the GH receptor (GHR) is a significant genetic predictor. The role of individual epigenetics had not been studied. The IGF1 locus is an attractive candidate where CG methylation could influence GH action.Objectives: To study GH effects on a) IGF1 gene...

CG Methylation at the IGF1 P2 Promoter is a Major Epigenetic Determinant of Postnatal, Not Foetal Growth

Ouni Myriam , Le Stunff Catherine , Castell Anne Laure , Bougneres Pierre

Background: The height of children has a Gaussian distribution. Genetics explain an important part of individual variability, but no single genomic variant accounts for more than 0.3% of height variance. At the interface of genetics and environment, epigenetics is expected to contribute to phenotypic variability. IGF1 is an attractive locus to test this hypothesis.Objectives: To quantify the effect of CG methylation of IGF1 promoters on height.<p cla...

Investigation into β-cell Adaptation During Puberty

Castell Anne-Laure , Ethier Melanie , Fergusson Grace , Ghislain Julien , Poitout Vincent

Background: Puberty is a time of hormonal changes that are associated with insulin resistance. Although insulin sensitivity is restored at the end of puberty in healthy youth, it does not resolve in obese adolescents leading to an increase of cardio metabolic disease such as type 2 diabetes. In response to an increase in insulin demand, as during pregnancy or obesity-induced insulin resistance, β-cells increase their functional mass to maintain glucose homeostasis. Howeve...

Insulin Pump Does Not Allow a Better Control than Injections in Childhood Type 1 Diabetes (T1d) in the ISIS-Diab Cohort

Fur Sophie Le , Castell Anne Laure , Lucchini Philippe , Bougneres Pierre , Network ISIS-Diab

Background: The use of insulin pumps is rapidly spreading within the paediatric T1D community. A few small studies have promoted pump usage, while large registries have shown almost no advantage of this treatment.Objectives: Compare the results of treatment with insulin pump (‘Pump’) with insulin injections (‘Inj’) in a large cohort of children with T1D in field conditions.Patients: We studied 3137 children of t...

Correction of Carnitine Deficiency in Children with Recent Onset Type 1 Diabetes

Castell Anne Laure , Bibal Cecile , Gaignard Pauline , De Filippo Gianpaolo , Bougneres Pierre

Background: Carnitine deficiency (CD) has been reported in children at time of type 1 diabetes (T1D) diagnosis. By impairing free fatty acid ß-oxidation in liver, muscle mass and pancreatic ß cells, CD might impair glucose homeostasis and residual insulin secretion. We postulate that reversed of these FAO defects may help regenerate a healthier ß cell mass and increased the diabetes honeymoon duration.Objective: Evaluate the effects of car...

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....

Very Low Estradiol Levels are Independent From Duration of Amenorrhea in Girls with Severe Anorexia Nervosa

Kyheng Christele , De Filippo Gianpaolo , Castell Anne-Laure , Flandrin Jennifer , Durin Julie , Delafoy Manon , Duranteau Lise

Background: Anorexia nervosa (AN) is a primary psychiatric disease, complicated by serious endocrine disturbances. Hypogonadotropic hypogonadism with primary or secondary amenorrhea is the most common endocrine repercussion of AN, with consequent estrogen deficiency and concerns about bone mineral density. Furthermore, establishing regular menstrual cycles is considered as one of the important milestones in girls treated for AN.Aim: To quantify the estro...

Type 1 Diabetes (T1D) Management with Few Blood Glucose (BG) Measurements but Frequent Free Adjustment of Treatment with Cell Phones or E-mails

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

Background: Many children with type 1 diabetes (T1D) are asked to measure blood glucose (BG) 4–6 times a day routinely to adjust insulin dosages. There is no evidence though that such high frequency is beneficial to HbA1C or glycemic profile, although this is often claimed.Objectives: We challenged ‘the more BG measurements, the better control’ dogma for alleviation of T1D burden in child life and evaluation of HbA1C.<p class="abstext"...

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 ...
