Miller Kellee , Hermann Julia , Maahs David , Hofer Sabine , Foster Nicole , Holl Reinhard

Objectives: To assess change in rates of pediatric CGM use over the past 5 years across demographic and clinical characteristics and association with hemoglobin A1c (HbA1c), data from 2 registries were compared: the US-based T1DX and the German/Austrian DPV.Methods: Registry participants in DPV and T1DX aged <18yrs with T1D duration ≥ 1yr with available data in any of the following years were included in the analysis (N for each year by registr...

Diabetes and Insulin Injection Modalities: Effects on Hepatic Expression and Activity of 11β-Hydroxysteroid Dehydrogenase Type 1 in Juvenile Diabetic Rats

Rougeon Veronica , Moisan Marie-Pierre , Barthe Nicole , Beauvieux Marie-Christine , Marissal-Arvy Nathalie , Barat Pascal

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...

MAP3K1 Mutation in a Patient with Complete XY Gonadal Dysgenesis

Kohler Birgit , Gehrmann Nicole , Gruters-Kieslich Annette , Bignon-Topalovic Joelle , McElreavey Kenneth , Bashamboo Anu

Background: 49,XY gonadal dysgenesis (GD) is a very rare disorder of testes development with an incidence of 1:50–100 000. MAP3K1 is a MAPK that mainly regulates the MAPK pathways. High Map3k1 expression was found in female and male mice gonads at 13.5 dpc. In 2010, MAP3K1 mutations were identified in two families with complete and partial XY GD and in two unrelated sporadic cases with complete XY GD (Pearlman 2010 AJMG). Recently, four additional mutations (four out of 4...

Rationale for a reduced dexamethasone dose in prenatal congenital adrenal hyperplasia therapy based on pharmacokinetic modelling

Neumann Uta , Stachanow Viktoria , Blankenstein Oliver , Fuhr Uwe , Huisinga Wilhelm , Reisch Nicole , Kloft Charlotte

Context: Prenatal dexamethasone (Dex) therapy is used in female foetuses with congenital adrenal hyperplasia (CAH) to suppress adrenal androgen excess and prevent virilisation of the external genitalia. The prenatal dexamethasone dose of 20 µg/kg/d has been used for decades in prenatal CAH. Despite the risks for the treated mother and potentially for the unborn child, no clinical study or evaluation had been conducted in order to determine a Dex dose with a scientific rat...

Successful transition in Congenital Adrenal Hyperplasia - A single centre experience over 20 years

Kiewert Cordula , Jedanowski Julia , P. Hauffa Berthold , Petersenn Stephan , Führer Dagmar , Unger Nicole

Introduction: Transition medicine aims at the coordinated transfer of young patients with a chronic disease from paediatric to adult specialist care. The present study reflects 20 years of experience in transitioning patients with congenital adrenal hyperplasia (CAH) in a single centre university setting.Methods: The endocrine transition clinic was established in 2002 and offers joint consultations with a paediatric and ...

Absence of Puberty and Estrogen Resistance by Estrogen Alpha Receptor Inactivation in Two Sisters: A Mutation for Variable Phenotypic Severity

Delcour Clémence , Khawaja Nahla , Mammeri Hedi , Drira Leila , Chevenne Didier , Ajlouni Kamel , De Roux Nicolas

Introduction: Estrogens play an essential role in reproduction and their peripheral action is mediated via nuclear alfa and beta receptors (ER) as well as membrane receptors. To date, only 3 females and 2 males from 3 families with a loss of function of ERa have been reported. The phenotype in these families was strongly suggestive of an estrogen resistance with an absence of a complete puberty, a delay in epiphyseal maturation with high estradiol levels and e...

Untargeted Plasma Metabolomics in Subjects with Differences in Tissue Glucocorticoid Sensitivity Identifies a Novel metabolic Signature

Nicolaides Nicolas C. , Ioannidi Maria-Konstantina , Koniari Eleni , Sertedaki Amalia , Klapa Maria I. , Chrousos George P. , Charmandari Evangelia

Background: Tissue glucocorticoid sensitivity is characterized by a considerable variation in terms of therapeutic response and side effects to synthetic glucocorticoids. The multi-metabolite concentration profile measured by untargeted plasma metabolomics provides a comprehensive metabolic signature that might be used in clinical practice.Objective and Hypotheses: To investigate the usefulness of plasma metabolomics in identifying a metabolic signature ...

Fracture Epidemiology for Children in Western Australia between 2005–2015: Do We Need to be Concerned about Bone Health?

Jenkins Mark , Nimphius Sophia , Hart Nicolas , Chivers Paola , Rantalainen Timo , Ruter Kristina , Borland Meredith , McIntyre Fleur , Stannage Katherine , Siafarikas Aris

Aim: Western Australia is a state with unique geography and population distribution having only a single tertiary paediatric hospital (Princess Margaret Hospital, PMH in Perth) managing the majority of children and adolescents with fractures in the Emergency Department (ED). Fracture incidence in 0–16 year olds is known to be high and varies between countries with boys having a 1.5 fold higher fracture incidence than girls. There are no specific data for Australia. The ai...

Background: Accumulating evidence suggests that decreased 25-hydroxyvitamin [25(OH)D] concentrations are associated with components of the metabolic syndrome.Objective: The aim of our study was to investigate the effect of vitamin D supplementation on metabolic syndrome parameters in obese children and adolescents.Patients and methods: Two hundred thirty two (n=232) obese children and adolescents aged [mean ±S....

Transcriptomic Analysis in Healthy Subjects with Differences in Tissue Sensitivity to Glucocorticoids Identifies Novel Disease-associated Genes

Nicolaides Nicolas C. , Polyzos Alexandros , Koniari Eleni , Lamprokostopoulou Agaristi , Golfinopoulou Eleni , Papathanasiou Chryssanthi , Sertedaki Amalia , Thanos Dimitris , Charmandari Evangelia

Background: Glucocorticoids exert profound immune-modulating effects and regulate the expression of genes involved in cell cycle progression and apoptosis. Synthetic glucocorticoids are the most potent agents used in the treatment of inflammatory, autoimmune and lymphoproliferative disorders. Considerable variation in response to therapeutic doses of glucocorticoids exists among individuals, as evidenced by differences both in disease response and in the incidence of glucocort...
