GH Unmasked Laryngomalacia and worsened Obstructive Sleep Apnea in Infants with Prader-Willi Syndrome

Salehi Parisa , Wrede Joanna E , Johnson Kaalan E , Chen Maida L

Background: Prader-Willi Syndrome (PWS), due to loss of paternal gene expression on chromosome 15q11.2-13, is characterized by hypotonia, hypothalamic-pituitary dysregulation, abnormal respiratory drive, and hyperphagia. GH, often started in infancy, improves tone, body composition, and height. Concerns about sudden death in children with PWS started on GH, hypothesized secondary to worsening obstructive sleep apnea (OSA) from adenotonsillar hypertrophy, resulted in guidelines...

Altered Stress System Activity in Children with ADHD

Angeli Eleni , Johnson Elizabeth , Korpa Terpsichori , Apostolakou Filia , Papassotiriou Ioannis , Chrousos George , Pervanidou Panagiota

Background: Attention-deficit/hyperactivity disorder (ADHD) is the most prevalent neurodevelopmental disorder worldwide. Evidence suggests dysfunction of the fronto-subcortical pathways and the dopaminergic and noradrenergic systems, as well as dysregulation of the stress system, i.e., the hypothalamic–pituitary–adrenal (HPA) axis and the sympathetic nervous system (SNS).Objective and hypotheses: The aim of the study was to examine i) the diurn...

A Novel Non-Invasive Short Synacthen Test

Elder Charlotte , Johnson Trevor , Loxley Martin , Keevil Brian , Wales Jerry , Wright Neil

Background: The short synacthen test (SST) is a popular diagnostic investigation for adrenal insufficiency (AI). Cannulation and blood sampling are required making it invasive, time-consuming and resource-intensive. Salivary cortisol is a well-established alternative to serum sampling.Objective and Hypotheses: To develop a non-invasive alternative to the 1 μg SST, using a novel formulation of Synacthen (with a nasal drug enhancer, chitosan) given na...

Mortality in children with monogenic diabetes

Globa Eugenia , Zelinska Natalia , Franco Elisa De , Houghton Jayne , Johnson Matthew , Ellard Sian ,

Background: In this study we investigated mortality in children with monogenic diabetes.Methods: Within the Ukrainian Pediatric Diabetes Register (UPDR) the number of children with type 1 diabetes mellitus (DM1) 0-17 y.o. in 2019 was 9860 (1 in 769), with DM2 - 36 (1 in 210,547) with neonatal DM (NDM) - 66 (1 in 115,000), with MODY - 40 cases (1 in 114,844). We used targeted next generation sequencing (tNGS) of all known...

Congenital hyperinsulinism diagnosed after 12 months can have a monogenic aetiology

Hopkins Jasmin , Childs Alexandra , Hewat Thomas , Patel Kashyap , Houghton Jayne , Johnson Matthew , Laver Thomas , Flanagan Sarah ,

Background: Congenital hyperinsulinism (HI) is characterised by inappropriate insulin secretion despite low blood glucose which is commonly diagnosed in infancy (before the age of 12 months). Screening of the >20 known genes identifies a mutation in over 45% of cases. The likelihood of identifying a mutation in a known gene in individuals diagnosed after 12 months is not currently known.Aim: We aimed to identify the ...

High-dose steroids in the management of Paediatric Multisystem Inflammatory Syndrome Temporally associated with SARS-CoV-2 (PIMS-TS): Considering the hypothalamic-pituitary-adrenal axis

McGlacken-Byrne Sinead M , Johnson Mae , du Pre Pascale , Katugampola Harshini ,

Background: Steroid therapy has been used as a therapeutic strategy in the management of Paediatric Multisystem Inflammatory Syndrome Temporally associated with SARS-CoV-2 (PIMS-TS) with good effect. However, as always, exogenous steroid administration carries with it a risk of iatrogenic adrenal insufficiency.Aim: We characterise steroid therapy use in PIMS-TS and consider implications for hypothalamic-pituitary-adrenal...

Clinical Case of Cystic Fibrosis-like and APECED-like Syndrome due to Gain-of-Function Variant in STAT1

Vasilev Teodor , Johnson Matthew , Yaneva Natasha , Slavcheva Olga , Modeva Iskra , Hattersley Andrew , Savova Radka ,

Background: STAT1 mutations can cause an extensive spectrum of disease, varying from severe bacterial and viral infections to mild disseminated mycobacterial disease, also chronic mucocutaneous candidiasis. Many patients present with autoimmune manifestations as type 1 diabetes, hypothyroidism and systemic lupus erythematosus. There are risks of cancers and cerebral aneurysms.Aim: To present the clinical manifes...

A Novel Non-invasive Short Synacthen Test Validated in a Healthy Paediatric Population

Elder Charlotte , Vilela Ruben , Johnson Trevor , Kemp E Helen , Keevil Brian , Newell-Price John , Ross Richard , Wright Neil

Introduction: Worldwide the Short Synacthen Test (SST) is the most popular diagnostic investigation for adrenal insufficiency (AI) amongst both paediatric and adult endocrinologists. Cannulation and blood sampling are required making it invasive, time-consuming and resource-intensive. We have previously validated a reliably absorbed and well tolerated formulation of nasal synacthen (Nasacthin003) in healthy adult males, measuring the glucocorticoid response in salivary cortiso...

Variability of advice and education for steroid sick day dosing in Duchenne Muscular Dystrophy and the impact of the COVID-19 pandemic: Results of a UK wide patient survey

Thakrar S , Cheung MS , Johnson A , Katugampola H , Manzur A , Muntoni F , Mushtaq T , Turner C , Wood C , Guglieri M , Wong SC ,

Introduction: The use of long-term oral corticosteroid in DMD is associated with a range of side effects including secondary adrenal insufficiency. The updated international care consensus (2018) recognizes this important issue and recommends emergency plans to be in place.Aim: This online UK-wide patient survey aims to determine the advice and education given for sick day dosing plans and the impact of the COVID-19 pand...

Evaluation of Prepubertal Patients with Suspected Neurosecretory Dysfunction of Growth Hormone Secretion: Diagnostic Steps and Treatment Response

Sydlik Carmen , Weiszenbacher Claudia , Pozza Susanne Bechtold-Dalla , Schmidt Heinrich

Background and aims: Existence and diagnostic procedures of neurosecretory dysfunction (NSD) are still a matter of debate. The aim of the study was to analyse prediagnostic data of short-statured children with pathologic and normal spontaneous GH-secretion and to evaluate the effect of GH-therapy in NSD-patients.Methods: Of 90 children aged 3–16 years, in whom 12-hour night profiles for GH-secretion were performed (unicentric), in 49 NSD was diagnos...
