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...

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% ...

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...

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...

Background: Treatment adherence to daily subcutaneous rhGH is a burden for GHD patients, with noncompliance reported in up to 77% of patients and significantly associated with reduced efficacy (Rosenfeld Endocr Pract 2008; Cutfield PLoS One 2011). Somavaratan, a novel rhGH fusion protein with t1/2 >100 h, demonstrated clinically meaningful improvements in height velocity and IGF-I in prepubertal children with GH deficiency (GHD) in a multicenter, randomized, Pha...

Background: TransCon GH is designed as a once-weekly sustained-release prodrug of recombinant human GH (hGH, somatropin). Based on the inert TransCon prodrug technology unmodified native hGH is released with a Cmax and AUC comparable to daily therapy. TransCon GH leverages the known pharmacology of daily hGH and is being developed for the treatment of GH deficiency (GHD) in children and adults.Objective and hypotheses: Develop a safe and efficacious sust...

Background: Diencephalic syndrome (DS) is a rare disorder of severe emaciation classically associated with infantile Hypothalamochiasmatic low-grade gliomas (HCLGGs) and GH excess. However, diagnostic criteria remain undefined and published literature includes non-specific tumour-related cachexia. In a large optic pathway LGG cohort (n=166), we have previously demonstrated that DS independently predicts multiple tumour progressions and severe endocrine morbidity.<...

Backgrounds: The prevalence of congenital malformations (CM) is higher in infants referred with capillary (c) TSH elevation on newborn screening. However, establishing the prevalence of CM ± dysmorphic syndromes in true congenital hypothyroidism (CH) requires careful distinction between true and transient CH.Objective: To determine the prevalence of CM ± dysmorphic syndromes in all infants referred with TSH elevation on newborn screening in Sco...

Background: Bone mass is low in obese children when measured by conventional techniques. However, these imaging modalities cannot quantify alterations in bone microstructure and strength. High resolution peripheral quantitative computed tomography (HRpQCT – isotropic voxel size 82 mm) provides the resolution required to determine 3-dimensional in-vivo bone microstructure; microfinite element (microFE) analysis of HRpQCT images provides insight into skeletal biome...

Background: Short stature is a recognized complication of Crohn’s disease (CD) in children. Less is known on the impact of disease on final adult height and body proportions.Objective and hypotheses: To assess height and body proportions in 48 adults (F: 30; M: 18) with childhood (ACO) or adult (AAO) onset CD and 44 children (C) (F:22; M:22) with CD.Method: Standing, sitting height (SH) and leg length (SILL) were measured and ...
