Adherence with Twice-Monthly, At-Home Dosing Schedule of Somavaratan (VRS-317) Long-Acting Growth Hormone Treatment in Children with Growth Hormone Deficiency (GHD) (NCT02068521)

Humphriss Eric , Sheikh F. Naureen , Seaman Morgan , Ng David , Bright George

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...

Design and Clinical Development of TransCon Growth Hormone for Growth Hormone Deficiency (GHD)

Beckert Michael , Gilfoyle David , Mikkelsen Jan Moller , Rasmussen Grethe , Rau Harald , Sprogoe Kennett

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...

Efficacy of Growth Hormone Treatment in Patients with Type 1 Diabetes Mellitus and Growth Hormone Deficiency

Bonfig Walter , Lindberg Anders , Cutfield Wayne , Dunger David , Camacho-Hubner Cecilia , Holl Reinhard W

Background: The combination of type 1 diabetes mellitus (T1DM) and GH deficiency is uncommon. In a previous study (1) we found that in children with T1DM and GHD with adequate adaptation of insulin dosage, the metabolic control of T1DM did not worsen during GH treatment. However, decreased catch-up growth was observed and no data on GH dose was available.Objective: To analyse first year treatment growth response and GH dosage in prepubertal patients with...

The Diencephalic Syndrome of Emaciation in Infantile Hypothalamochiasmatic Low-Grade Gliomas : a Retrospective Case–Control Study of Diagnostic Parameters and Long-Term Outcomes Over 30 Years of Follow-Up

Gan Hoong-Wei , Meijer Lisethe , Gullick Georgina , Senbanjo Margaret , Walker David , Spoudeas Helen

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.<...

Management of Hyperhydration in a Child with Syndrome of Inappropriate Antidiuretic Hormone Secretion (Siadh) Using a Selective Vasopresin Receptor Agonist

Delgado-Carballar Violeta , Thankamony Ajay , Willemsen Ruben , Elleri Daniela , Dunger David

Background: Management of SIADH is challenging and no optimal therapies are available in children. We present a case of an 11 years old boy with severe SIADH resistant to 30% fluid restriction in the context of an intracranial suprasellar high grade B-cell lymphoma who requires hyperhydration for chemotherapy protocol. Tolvaptan is an oral highly selective arginine vasopressin V2 receptor antagonist, which has been approved for use in SIADH in adults.Obj...

The Prevalence of Congenital Malformations in Infants with TSH Elevation on Newborn Screening: the Importance of Distinguishing Between True and Transient Congenital Hypothyroidism

Ouarezki Yasmine , Mansour Chourouk , Jones Jeremy , alghanay Abubaker , Smith Sarah , Stone David , Donaldson Malcolm

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...

Opposing Effects of Childhood Obesity on Radial and Tibial Bone Microstructure

Dimitri Paul , Jacques Richard , Paggiosi Margaret , King David , Walsh Jennifer , Bishop Nick , Eastell Richard

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...

Infancy Lipidomic Analyses and Associations with Early Nutrition and Growth

Prentice Philippa , Koulman Albert , Matthews Lee , Acerini Carlo , Ong Ken , Dunger David

Background: Links between early life exposures and long-term health outcomes may in part be due to nutritional programming, and suggested benefits of breast feeding during infancy include reduced risk of obesity and metabolic disease. Mechanisms remain unexplained but potential differences in lipid exposures during infancy may be involved.Objective and hypotheses: To explore the effects of breast- or formula-feeding on lipidomic profiles we used recently...

Prenatal Exposure to Phthalates and Phenols in Relation to Anogenital Distance at Birth in Male Infants

Fisher Benjamin G , Thankamony Ajay , Ong Ken K , Dunger David B , Hughes Ieuan A , Acerini Carlo L

Introduction: Increasing incidence of male reproductive disorders may be due to fetal exposure to putative endocrine disruptor chemicals (EDCs), such as phthalates and phenols. Anogenital Distance (AGD) is a biomarker of fetal androgen action in animals, and has recently been linked to testicular dysgenesis syndrome in humans.Objective: To examine the relationship between prenatal phthalate and phenol exposure and birth AGD in male infants.<p class="...

The Effects of Delaying Puberty with GnRH Agonists in Patients with Idiopathic GH Deficiency

Dunger David B , Lindberg Anders , Dorr Helmut G , Camacho-Hubner Cecilia , Geffner Mitchell E

Background: Treating central precocious puberty with GnRH agonist (GnRHa) to increase height gain is well-established. Although not recommended, GnRHa have also been used in patients with IGHD at onset of puberty yet there are few data on its efficacy.Objective and hypotheses: Growth prediction models derived from KIGS (Pfizer International Growth Database) may provide an opportunity to estimate additional height gain produced by pubertal blockade.<p...
