A Novel Stem Cell Model for the Triple A Syndrome

Da Costa Alexandra Rodrigues , Qarin Shamma , Bradshaw Teisha Y. , Watson David , Prasad Rathi , Barnes Michael R. , Metherell Louise A. , Chapple J. Paul , Skarnes William C. , Storr Helen L.

Triple A syndrome (AAAS) is a rare, incurable, recessive disorder, characterised by achalasia, alacrima, adrenal failure and a neurodegenerative phenotype. The AAAS gene encodes ALADIN, is a nuclear pore complex (NPC) protein necessary for nuclear import of DNA protective molecules, important for redox homeostasis. ALADIN’s role is not fully characterised: its discovery at the centrosome and the endoplasmic reticulum suggests a role outside the NPC. To date, the ...

Burosumab, a Fully Human anti-FGF23 Monoclonal Antibody, for X-linked Hypophosphatemia (XLH): Sustained Improvement in two Phase 2 Trials in Affected Children 1–12 years old

In XLH, excess fibroblast growth factor 23 (FGF23) causes hypophosphatemia and consequent rickets, skeletal deformities, and growth impairment. The efficacy and safety of burosumab, a fully human monoclonal antibody against FGF23, was evaluated in two Phase 2 trials in children with XLH. In CL201, 52 children with XLH (5–12 years old, Tanner ≤2) were randomized 1:1 to receive subcutaneous burosumab every 2 (Q2W) or 4 (Q4W) weeks, with doses titrated up to 2 mg/kg to...

Introduction: Rare mutations of the ESR1gene, encoding the estrogen receptor alpha (ERα), have been shown to cause estrogen resistance in humans. To date, there are no effective therapeutic options. We report the case of a new inactivating mutation of ERα and provide evidence for a partial restoration of biological effects of estrogen.Methods: We performed clinical and biological phenotyping of the index case and sequenced the ESR1...

New Insights into Low Dose Dexamethasone Suppression Test in Paediatric Cushing’s Syndrome

Wilkinson Ingrid C E , Martin Lee , Grossman Ashley B , Monson John P , Akker Scott , Savage Martin O , Drake William M , Storr Helen L

Background: The Low dose dexamethasone suppression test (LDDST) is an important investigation for suspected Cushing’s Syndrome (CS). The traditional definition of normal suppression of serum cortisol to ≤50 nmol/l during the LDDST (0.5 mg 6 hrly × 48 h) comes from a time when biochemical autoanalysers did not routinely detect very low values. Previous studies reported 5.1–8.3% of patients with Cushing’s Disease (CD) suppressed to <50 nmol/l at 48 ...

24-H Urinary Free Cortisol as a Screening Test for Cushing’s Syndrome in Children

Shapiro Lucy , Elahi Shezan , Baliey Joe , Perry Les , Martin Lee , Grossman Ashley , Akker Scott , Monson John , Drake William , Savage Martin , Storr Helen

Background: Cushing’s syndrome (CS) in children remains a challenge to diagnose and exclude. Published diagnostic guidelines for CS are heavily based upon adult data. The use of 24-h urinary free cortisol (UFC) measurements in the diagnosis of adult CS may have limited use. There is little data on the utility of 24-h UFC in children.Objective and hypotheses: We hypothesised that 24-h UFC is a robust and reliable screening test in children. The study...

Challenges Experienced in Delivering Growth Hormone Therapy in Children's with Prader Willi Syndrome in Birmingham Children's Hospital.

Kollurage D Udeni Anuruddhika , Barrett Tim , Jayamanne B D W , Krone Ruth

Prader Willi Syndrome (PWS) is a rare neuro-genetic disorder inherited as a result of lack of expression in 15q11-13 gene and 70% are paternally inherited. Characteristic features are dysmorphism, behavioural problems, infantile hypotonia, short stature, hypothalamic dysfunction, hyperphagia and morbid obesity. The long-term morbidity and mortality depend on hypothalamic dysfunction and obesity. While multidisciplinary care is essential, growth hormone (GH) is a recognized...

Background: Bone growth and mineralization during childhood are now recognized as important for bone health in adulthood, leading to renewed interest in identifying modifiable factors that impact bone mineral density (BMD) in childhood. Emerging data suggest that duration of breastfeeding may affect BMD in later childhood and adult life. However, such data are sparse and inconsistent.Objectives: This study examined the relationship betwe...

Follow-Up Evaluation of Clinical Markers and Inflammatory, Biochemical and Hormonal Profiles in Children with Bodyweight Problems

Ṭaranu Ioana , Bolboacă Sorana D. , Creţ Victoria

Introduction: In the last years, the relationship between clinical markers and blood parameters has been evaluated closely as part of transversal studies, but a longitudinal approach might be more useful in explaining its complexity.Aim: The study aims to evaluate the relationship between changes in the values of clinical markers and of the inflammatory, biochemical and hormonal profiles of obese and overweight children ...

I.V. Zolendronic Acid: Experience of Treatment of Children with Osteogenesis Imperfecta in Indonesia

Pulungan A , Zacharin M , Armstrong K , Soesanti F , Pramesti D L

Background: The incidence of osteogenesis imperfecta (OI) worldwide is unknown. In the USA, the incidence is ~1/20 000 live births: for Indonesia (population 240 million) this should extrapolate to 12 000 OI patients rather than the 35 patients currently registered with the Indonesian Pediatrics Society (IPS), Faculty of Medicine, University of Indonesia-Cipto Mangunkusumo Hospital (RSCM). This enormous disconnect signifies many missed diagnoses, mortality or both.<p class...
