Background and hypotheses: Recent results showing elevated tetrahydrocortisol/tetrahydrocorticosterone ratio (THFs/THE) in morning urines of diabetic children compared to controls suggest an increased nocturnal activity of 11 β-hydroxysteroid dehydrogenase type 1 (11β-HSD1). We made the hypothesis that a reduced inhibition of hepatic 11β-HSD1 activity by exogenous insulin, due to its subcutaneous (SC) administration and absence of first hepatic passage, could ex...

Background: Vitamin D may have cardio-protective properties due to its biological actions. In children, observational studies linking actual vitamin D level and blood pressure have yielded conflicting results. Whether early life vitamin D exposure may elicit a programming effect on later systolic blood pressure (SBP) and diastolic blood pressure (DBP) needs further investigation.Objective and hypotheses: We investigated whether higher levels of cord 25-h...

Background: A diagnosis of diabetes in children used to mean type 1 diabetes (T1D) and lifelong insulin therapy. However, over the last decades the spectrum of diabetes has widened and even if auto immunity remains the most prevalent etiology, confounding factors and overlap with other causes of diabetes types sometimes make a revision of the initial diagnosis necessary.Objective and hypotheses: To classify diabetes etiologies in youth with diabetes usin...

Background: Congenital adrenal insufficiency represents a life-threatening condition. Among its multiples causes, mutation of NNT1 is the most recently discovered. We had the opportunity to observe one case. NNT1 is a gene coding for a membrane protein which protects cells from oxidative stress.Objective and hypotheses: As few cases have been published until now, we describe a new case.Results: In a consanguineous (second grade) Al...

Background: Our first report of this randomized controlled trial (RCT) demonstrated improved treatment satisfaction but no difference in HbA1c between the CSII and MDI treated groups, and added to the controversy as to whether CSII improves HbA1c or not. Therefore, we thought it would be valuable to assess if CSII had other potential advantages and if our finding of lower insulin dose requirements could be explained.Objective and Hypotheses: To study how...

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...

Background: Final results from MEGHA study required by Health French Authorities (HAS).Objective and hypotheses: Objectives are to carry out longitudinal follow-up during maximum 5 years of AGHD patients treated with Saizen, with a description of prescription modalities, demographic and clinical characteristics, patient compliance, product safety, and quality of life.Method: MEGHA is a multicentric study, with prospective follow-up...

Inactivating mutations of ß-cell KATP channels cause the most common and severe form of congenital hyperinsulinism (HI), a ß-cell disorder that results in dysregulated insulin secretion and persistent hypoglycemia. Children with KATPHI are typically unresponsive to diazoxide, the only FDA-approved drug for HI. Octreotide, an SST2-selective agonist peptide that inhibits insulin secretion, is used as second line therapy, but poor efficacy and SST2...

Introduction: The human fetal adrenals (HFA) produce high levels of steroids. The gland is distinguishable from the 7th gestational week and can be separated in two zones: the fetal zone in the center which correspond of 80 % of the gland and the definitive zone in the periphery. At this time of the development, neural crest cells are reaching the adrenal primordium, producing catecholamines. A third zone, the transitional zone appears later in the early 2nd t...

Background: A combination of GH and a gonadotropin releasing hormone analogue (GnRH a) is hypothesized to improve adult height in children with a poor adult height prediction.Study design: In this multicenter study, 24 girls in early puberty (bone age ≤12.0 y),with a predicted adult height ≤151.0 cm and normal body proportions were treated with GH (Zomacton) 50 μg/kg per day and triptorelin (Gonapeptyl) 3.75 mg/month SC or IM (for 4 year...
