Recent Secular Change in Pre- and Postnatal Growth and Adiposity in Infants of Mothers with Gestational Diabetes

Olga Laurentya , Prentice Philippa , Hughes Ieuan , Acerini Carlo , Ong Ken , Dunger David

Objective: Typically, infants born to mothers with gestational diabetes mellitus (IOGDM) have greater risks for macrosomia, later obesity and metabolic diseases. However, we have noticed that birth weights of IOGDM have reduced over the last decade even with uniform application of the International Association of Diabetes and Pregnancy Study Group’s (IADPSG) consensus definition. We therefore compared infancy growth outcomes from two IOGDM cohorts born during non-overlapp...

Altered DNA Methylation in Peripheral T-cells from Patients with Congenital Adrenal Hyperplasia

Karlsson Leif , Barbaro Michela , Ewing Ewoud , Gomez-Cabrero David , Lajic Svetlana

Background: Patients with Congenital Adrenal Hyperplasia (CAH) are at risk of several co-morbidities, such as impaired cognitive functions, short stature and adverse effects on metabolism. The causes of these effects are suboptimal glucocorticoid replacement therapy, adrenal crises and prenatal glucocorticoid exposure. However, there are no data available to this day how these factors are affecting epigenomic programs.Objective and hypot...

Increasing Use of Continuous Glucose Monitoring (CGM) Among Youth with Type 1 Diabetes (T1D): Icomparison of Youth from the T1D Exchange (T1DX) and the DPV Initiative

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...

The Rationale and Design of TransCon GH

Sprogoe Kennett , Beckert Michael , Mortensen Eva , Karpf David B , Leff Jonathan A

Background: The fundamental challenge of developing a long-acting growth hormone (LAGH) is to create a more convenient growth hormone (GH) dosing profile while retaining the excellent safety, efficacy, and tolerability of daily GH. With GH receptors on virtually all cells, replacement therapy should achieve the same tissue distribution and effects of daily (and endogenous) GH while maintaining levels of GH and resulting IGF1 within the physiologic range....

Baseline Demographics of the TransCon GH Phase 3 heiGHt Trial

Beckert Michael , Karpf David B , Shu Aimee , Lin Zhengning , Leff Jonathan A

Background: TransCon GH is a novel sustained-release recombinant human GH (somatropin) prodrug in development for children with GH deficiency (GHD). It is designed to release unmodified GH and intended to provide comparable efficacy, safety, tolerability, and immunogenicity to daily GH with once-weekly dosing. Based on results from a phase 2 trial, which demonstrated comparable efficacy (annualized height velocity for TransCon 0.21 mg GH/kg per week of 12.9 cm/year vs 11.6 cm/...

Growth, Body Composition and Metabolic Parameters during Childhood in a Cohort of Children Born with a Small for Gestational Age

Loredana Marcovecchio M. , Gorman Samantha , Murgatroyd Peter , Ong Ken , Dunger David , Beardsall Kathryn

Aims: To examine growth, body composition and glucose metabolism during childhood in children born small for gestational age (SGA).Methods: Single centre cohort study of 150 children (63 boys), identified from newborn records as being born SGA (birth weight SDS <−1.5) and assessed between the age of 4 and 7 years. Data collected included: anthropometric parameters (height, weight, BMI: transformed into age- and sex-adjusted SDS), lean and fat m...

Patterns of Thyroglobulin Levels in Infants Referred With High TSH on Newborn Screening, Compared with Iodine-sufficient Healthy Controls

Kallali Wafa , Neumann David , Krylova Katerina , Jones Jeremy H. , Smith Karen , Shaikh Guftar , Donaldson Malcolm

Background: Thyroglobulin (Tg) is exclusively synthesised by thyroid tissue and a potentially useful aid to diagnosis in congenital hypothyroidism (CH). However, its role has yet to be fully evaluated.Objective: To examine the sensitivity and specificity of Tg in helping define the etiology of CH.Patients and methods: Tg was measured in a single laboratory by Immulite 2000 chemiluminescent immunometric assay (CVs 9.8, 5.7 and 5.7% ...

Evaluation of a Novel Method to Detect Residual ß-Cell Function by Dried Blood Spots in Children and Adolescents with a Recent Diagnosis of Type 1 Diabetes

Willemsen Ruben , Burling Keith , Ackland Fran , Edge Julie , Diaz Renuka , Barker Peter , Guy Catherine , Dunger David

Background: The majority of drug developments in type 1 diabetes (T1D) are aimed at preventing decline of beta cell function (BCF), as this has been associated with better glycaemic control and fewer long-term complications. Traditionally, BCF is evaluated by the C-peptide response to the labour-intensive mixed-meal-tolerance-test (MMTT), but there’s a need for a more practical alternative. We developed a new method to measure C-peptide in ‘dried blood spots’ (D...

Pharmacokinetic Modelling Predicts Native hGH Levels Following Administration of a Sustained-Release Prodrug, TransCon hGH, to Children with GHD

Sprogoe Kennett , Beckert Michael , Christoffersen Eva Dam , Gilfoyle David , Wegge Thomas

Background: TransCon Growth Hormone is a once-weekly sustained-release prodrug of recombinant human growth hormone (hGH, somatropin). Based on the inert TransCon prodrug technology unmodified hGH is released with a Cmax and AUC comparable to daily therapy. TransCon hGH leverages the known pharmacology of daily hGH and is being developed for the treatment of growth hormone deficiency (GHD).Objective and hypotheses: Both hGH levels and resulting IGF-I leve...

Neonatal Diabetes due to NKX2.2 Mutation – Genotype, Clinical Phenotype and Therapeutic Challenges in a Very Low Birth Weight Diabetic Neonate

Auerbach Adi , Shlomai Noa Ofek , Shokrun Ariella Weinberg , Levy-Lahad Ephrat , Zangen David

Background: Insulin treatment in a very low birth weight neonate having persistent hyperglycemia is challenging. The very recently reported novel human genetic cause of neonatal diabetes due to NKX2.2 pancreatic transcription factor mutations is associated with very low birth weight deliveries.Objective and hypotheses: To study the diagnostic process, the molecular genetics, the clinical phenotype, and the significant therapeutic challenges in the manage...
