Male Fertility Genes Located in Y-Chromosomal Regions Display Differential mRNA Profiles in Response to GnRH Treatment of Cryptorchidism-Dependent Infertility

Hadziselimovic Faruk , Gegenschatz-Schmid Katharina , Verkauskas Gilvidas , Stadler Michael

Background: Undescended testes in patients with defective mini-puberty contain germ cells that fail to differentiate normally into Ad spermatogonia and ultimately leads to infertility. Six months treatment with the gonadotropin-releasing hormone GnRH increases luteinizing hormone and testosterone secretion and rescues fertility in the majority of pathological cryptorchid testes. Several Y chromosomal genes in the male-specific Y region (MSY) are essential for spermatogenesis, ...

Identification of X-linked Adrenoleukodystrophy in Boys Presenting with Adrenal Insufficiency in the Absence of Adrenal Antibodies

Ryalls Michael , Gan Hoong-Wei , Biedenkapp Joe , Davison James

Adrenoleukodystrophy (ALD) is an X-linked, metabolic disorder caused by genetic deficiency of peroxisomal ALD protein resulting in accumulation of very-long chain fatty acids (VLCFA) primarily in the adrenal cortex and central nervous system. Approximately 35–40% of boys with ALD develop cerebral ALD (CALD), which causes rapidly progressive cerebral demyelination, loss of neurologic function, and death. Disease progress can be halted by allogeneic hematopoietic cell trans...

An Irish Regional Study of Paediatric Growth Hormone Deficiency (CO-GHD): Classification of Causes and Factors Associated with Persistent GHD at Transition

Grace Mariana , Joyce Caroline , Morissey Rose , Moore Michael , O'Connell Susan

Childhood-onset growth hormone deficiency (CO-GHD) is topical at present due to the increasing understanding of underlying genetic aetiologies, influence on childhood growth, and future effects on adolescence and adult health. There is no previous Irish data of this group of children.Methods: A retrospective cohort study over 2 years (2013-2015) including all children diagnosed with GHD who received recombinant growth hormone treatment (rGH). Predictors ...

In vitro Evidence that Growth Plate Chondrocytes Differentiate into Perichondrial Cells

Spath Stephan-Stanislaw , Andrade Anenisia , Chau Michael , Nilsson Ola

Background: During early bone formation, mesenchymal stem-cells condense and differentiate into collagen type 2-expressing chondrocytes which form the cartilaginous bone anlagen. This anlage becomes enclosed by the perichondrium. The perichondrium consists of two layers, the inner cambium layer containing chondrocyte- and osteo-precursor cells and the outer fibrous layer important for mechanical and structural support. While the regulation of the growth plate is increasingly w...

A Six-Month Safety and Efficacy Study of TransCon hGH Compared to Daily hGH in Pre-Pubertal Children with Growth Hormone Deficiency (GHD)

Chatelain Pierre , Malievsky Oleg , Radziuk Klaudziya , Senatorova Ganna , Beckert Michael

Background: TransCon hGH is a long-acting prodrug of recombinant human growth hormone (hGH) that releases fully active unmodified hGH into the blood compartment. This presentation will detail the final safety and efficacy results of TransCon hGH in a Phase 2 study in children with GHD over a treatment period of six months.Objective and hypotheses: The objective of this Phase 2 study in GHD was to investigate 1) safety and tolerability, 2) pharmacokinetic...

Pediatric Phase 2 Data Demonstrate that TransCon hGH Has an Anti-hGH Immunogenic Profile that is Comparable to Daily hGH

Gilfoyle David , Pihl Susanne , Chatelain Pierre , Beckert Michael

Background: TransCon hGH, is a once-weekly prodrug releasing unmodified hGH, for the treatment of Growth Hormone Deficiency (GHD) in children and adults. To date, TransCon hGH has demonstrated comparable efficacy, safety and anti-hGH immunogenic profile to daily hGH, with no occurrence of neutralizing antibodies.Objective and hypotheses: Protein-based therapies may be associated with generation of drug-specific antibodies, which may impact efficacy, part...

Effects of a Stressful Environment (SE) on Height, BMI and Menarche

German Alina , Mesch Gustavo , Shmoish Michael , Hochberg Ze'ev

Background: Children’s exposure to stress predicts poor health. Poor growth and maturation are recognized indicators of poor health.Objective and hypotheses: SE correlates with height, BMI and menarche. We correlated seven indicators of SE with countries’ average adult height, BMI and menarche age.Method: Data for 57 countries of average men and women’s height, BMI and menarche age were collected from WHO report. The...

A Multicentre Study Evaluating the Risk and Prevalence of Diabetic Retinopathy in Children and Young People with Type 1 Diabetes Mellitus

Ng Sze May , Ayoola Omolola O , McGuigan Michael , Chandrasekaran Surendran

Background: There is currently limited data published on the prevalence of diabetic eye disease in children and young people (CYP) with type 1 diabetes mellitus (T1DM), yet diabetic retinopathy remains one of the commonest causes of blindness in young adults.Objectives: To determine the risk and prevalence of diabetic retinopathy and to evaluate the risk factors associated with diabetic retinopathy in CYP with T1DM.Methods: All CYP...

A Phase 2, 6-Month, Randomised, Active-Controlled, Safety and Efficacy Study of TransCon hGH Compared to Daily Human GH in Children with GH Deficiency

Chatelain Pierre , Malievsky Oleg , Radziuk Klaudziya , Senatorova Ganna , Beckert Michael

Background: TransCon human GH (hGH) is a long-acting prodrug of recombinant hGH that releases fully active unmodified hGH. TransCon hGH was shown in phase 1 studies in healthy volunteers and a phase 2 study in adults with hGH deficiency to: i) be safe and well tolerated, ii) provide dose-dependent hGH levels, with same peak level and exposure compared to daily GH, iii) be suitable for a once-weekly dosing regimen, and iv) induce an IGF1 response within the normal range. This o...

Cholestatic Hepatopathy and Hypoglycaemic Seizures as Primary Manifestation of Hypocortisolism in Infancy

Saupp Peter , Fried Michael , Bergmann Carsten , Meissner Thomas , Kummer Sebastian

Background: Cholestatic hepatopathy is a rare but serious threat to neonates and young infants. Their immature hepatic excretory function predisposes for severe and rapidly progressive hepatic injury. Because of the wide range of possible etiologies, it is often difficult to make an accurate diagnosis. One rare endocrine cause can be primary or secondary hypocortisolism.Case presentation: i) A 7-week-old term-born female with cholestasis, elevated liver ...
