Background: Heterozygous mutations in the IGF1 receptor (IGF1R) are often associated with congenital IGF1 resistance, causing variable degrees of intrauterine growth retardation (IUGR) and postnatal short stature. To date, only one homozygous IGF1R mutation has been reported, in a child presenting with severe growth failure, mild intellectual impairment, microcephaly, dysmorphic features, and cardiac malformations.Objective: We now repo...

Baseline Cortisol Concentrations Predict Positively and Negatively Anti- and Pro- Oxidation, Respectively that are Measured Following an Acute Aerobic Exercise Bout in Pre- and Early Pubertal Normal-Weight and Obese Boys

Paltoglou George , Papagianni Maria , Fatouros Ioannis G. , Mantzou Aimilia , Jamurtas Athanasios , Avloniti Alexandra , Stefanaki Charikleia , Kanaka-Gantenbein Christina , Chrousos George P. , Mastorakos George

Background: Little data exist regarding the hypothalamic-pituitary-adrenal (HPA) axis activation and the interplay between the HPA axis and markers of pro- and anti-oxidation in children, following an acute aerobic exercise bout in children.Objective and hypotheses: To investigate the changes of HPA axis hormones following an acute bout of aerobic exercise and their respective association with markers of pro- and anti- oxidation in normal weight and obes...

Exposure to Phthalates and Phenols in Relation to Gestational Blood Glucose Homeostasis

Fisher Benjamin G. , Frederiksen Hanne , Andersson Anna-Maria , Juul Anders , Thankamony Ajay , Ong Ken K. , Dunger David B. , Hughes Ieuan A. , Acerini Carlo L.

Background: Endocrine disrupting chemicals (EDCs), such as phthalates and bisphenol A (BPA), have been associated with insulin resistance (IR) and type 2 diabetes (T2D) in non-pregnant adults. By contrast, recent pilot studies of pregnant women found negative associations between phthalates and blood glucose, and a lack of association with BPA. No studies have examined gestational IR or secretion in relation to EDC exposure.Objective: To confirm these re...

Growth and Endocrinopathy in Wolfram Syndrome: The Experience of a Nationally Commissioned Specialist Clinic

Kershaw Melanie , Gleeson Susan , Williams Denise , Gupta Rajat , Ainsworth John , Kulkarni Archana , McCarthy Liam , MacPherson Lesley , Bates Rachel , McGee Marie , Barrett Timothy G

Background: Wolfram syndrome (WS) is a monogenic disorder associated with diabetes mellitus (DM), optic atrophy, diabetes insipidus (DI), neurological deterioration and deafness. Growth has been poorly characterised in case series.Objective and hypotheses: To determine growth and prevalence of endocrine disorders, qualify therapies and metabolic outcome for DM, and relationship of cranial MRI findings to clinical findings in children and young people (CY...

Abdominal fat Distribution Measured by Magnetic Resonance Imaging in 197 Children Aged 10–15 Years – Correlation to Anthropometry and Dual X-Ray Absorptiometry

Tinggaard Jeanette , Hagen Casper P , Mouritsen Annette , Mieritz Mikkel G , Wohlfahrt-Veje Christine , Fallentin Eva , Larsen Rasmus , Christensen Anders N , Jensen Rikke B , Juul Anders , Main Katharina

Background: Obesity in childhood is defined by age- and sex-specific BMI cut-off values. However, BMI does not disclose the distribution of fat mass. Increased abdominal adipose tissue is associated with a higher risk of cardio-metabolic disease in adulthood. Thus, precise measurements of abdominal adipose tissue in children may enable early prevention of disease.Objective and hypotheses: To validate measurements of abdominal adipose tissue by anthropome...

Untargeted Plasma Metabolomics in Prepubertal ICSI and Naturally Conceived Children Unravels Gender: Dimorphic Metabolic Trajectories After ICSI

Background: ICSI is an assisted reproduction technique (ART) mainly used to overcome male infertility. Nowadays, ICSI is employed frequently due to its high success rate, despite it being highly invasive (i.e. epigenetic risk). Recent studies in ART offspring show a higher incidence of cardio-metabolic risk than in naturally-conceived (NC) controls. Thus, in our prior untargeted metabolomic study between ICSI and NC prepubertal girls, we demonstrated insulin resistance in the ...

Kinetics of FT4 serum concentrations in newborns and infants with congenital hypothyroidism during follow-up differ in the three severity groups

Steffens Britta , Gächter Pascal , Koch Gilbert , l'Allemand Dagmar , Janner Marco , Konrad Daniel , Welzel Tatjana , Pfister Marc , Szinnai Gabor

Background: The goal of congenital hypothyroidism (CH) treatment is rapid normalization and maintenance of TSH and FT4 in the reference range. Recommended starting dose of levothyroxine (LT4) ranges from 10-15 mg/kg/d. Hyperthyroxinemia can be accepted in the context of normal TSH and LT4 should only be reduced in case of symptoms or repeatedly increased FT4. The aim of this study was to quantify duration and maximum peak of FT4 levels outside the reference range for each CH s...

Introduction: Neonatal diabetes, defined as the onset of diabetes within the first six months of life, is very rare disease. Several genetic factors caused to neonatal disease have been identified to date. PTF1A (pancreatic transcription factor 1a) play a key role in early pancreas development and cerebellar neurogenesis. Biallelic mutations in PTF1A have been reported in patients with pancreatic and cerebellar agenesis, whereas mutations loc...
