The Side-Effects of Lanreotide in Children with Congenital Hyperinsulinism (CHI): A Decade-long Exploration

Malhotra Neha , Yan Georgina , Morgan Kate , Gilbert Clare , Doodson Louise , Gan Chin , Dastamani Antonia

Background: Lanreotide, a prolonged-release somatostatin analogue, has been utilized off-label for nearly a decade to treat cases of congenital hyperinsulinism (CHI) that do not respond to diazoxide. Acute side-effects of Lanreotide include diarrhoea and topical allergic reactions. Long-term effects include hepatitis, gallstones, growth suppression, hypothyroidism and gastrointestinal dysmotility. However, limited number of case series have documented the long...

Genetic screening and tumour surveillance program outcomes in rare paediatric hereditary endocrine tumour syndromes

Oprea Alina , Izatt Louise , Ajzensztejn Michal , Snow Emma , Carroll Paul , Wei Christina

Background: Hereditary syndromic endocrine tumours are associated with significant morbidity in the paediatric population. Advances in molecular genetics enable early cascade genetic testing with early initiation of tumour screening. Controversy exists around the start age and burdens arising from screening-related harms.Objective: To describe the efficiency of the screening program for paediatric patients with genetic r...

Characterising the natural history of Multiple Endocrine Neoplasia 2B caused by M918T RET pathogenic variants in children and young people

McGlacken-Byrne Sinead , Butler Colin , Abdel Aziz Tarek , Izatt Louise , Brain Caroline , Kurzawinski Tom

Aim: We describe the natural history, treatment, and clinical outcomes of Multiple Endocrine Neoplasia type 2B (MEN2B) caused by the M918T RET pathogenic variant.Methods: Retrospective case notes review of all young people <18 years presenting to a quaternary paediatric endocrinology referral centre in the UK between 2005-2023 who have MEN2B caused by the M918T pathogenic variant in the RET proto-onc...

Three-year results on weight and eating disorders with digi-physical treatment in paediatric obesity: A pragmatic clinical trial

Hagman Emilia , Lindberg Louise , R. Putri Resthie , Drangel Andreas , Marcus Claude , Danielsson Pernilla

Background: The integration of mobile health technology with a limited number of physical visits shows promising treatment outcomes, but long-term evidence is lacking. Additionally, concerns about eating disorders following obesity treatment are common among families and caregivers, although data on this matter are scarce for children and adolescents. This study evaluates three-year weight outcomes for patients using a digi-physical treatment tool and reviews ...

Mutations in MAGEL2 and L1CAM are Associated with Congenital Hypopituitarism and Arthrogryposis

Gregory Louise C , Pratik Shah , Sanner Juliane RF , Arancibia Monica , Hurst Jane , Jones Wendy D , Spoudeas Helen , Le Quesne Stabej Polona , Ocaka Louise , Loureiro Carolina , Martinez-Aguayo Alejandro , Williams Hywel , Dattani Mehul T

Background: Congenital hypopituitarism (CH), involving deficiencies in one or more anterior pituitary hormones, is rarely observed in combination with severe joint contractures, termed arthrogryposis. Schaaf-Yang syndrome (SHFYNG), which has phenotypic overlap with Prader-Willi syndrome, may be associated with arthrogryposis. L1 syndrome, a group of X-linked disorders including hydrocephalus and spasticity of the lower limbs, may also present with generalized contractures in r...

Thioredoxin Reductase 2 (TXNRD2) Variant As A Cause Of Micropenis, Undescended Testis And Selective Glucocorticoid Deficiency

Patjamontri Supitcha , Lucas-Herald Angela , McMillan Martin , Prasad Rathi , Metherell Louise , McGowan Ruth , Tobias Edward , Faisal Ahmed S.

Introduction: The molecular aetiology of familial glucocorticoid deficiency (FGD) is very heterogeneous. A recent report of a genetic variant in TXNRD2, the gene encoding thioredoxin reductase Type 2, in a South Asian kindred with FGD suggests that the maintenance of redox balance may be critical for adrenocortical function. We present the second report of an individual from another south Asian family harbouring a different pathological variant in <em...

The Incidence of Congenital Combined Pituitary Hormone Deficiency in Denmark - a national observational study

Kjersgaard Jakobsen Louise , Beck Jensen Rikke , Holtum Birkebæk Niels , Hansen Dorte , Rønholt Christensen Ann-Margrethe , Thybo Christesen Henrik

Background: Congenital combined pituitary hormone deficiency (cCPHD) is the loss of ≥2 pituitary hormones caused by genetic or prenatal factors.Methods: For the period 1996–2020, patients with cCPHD were identified from the Danish National Patient Registry and the registries at the four Danish hospitals approved for the management of cCPHD. Retrospective hospital file reviews were performed to validate the diagn...

A rare heterozygous IGFI variant causing impaired IGF-I cleavage and postnatal growth failure: a novel disease mechanism with insights into IGF-I physiology

Cottrell Emily , Andrews Afiya , Williams Jack , Chatterjee Sumana , Edate Sujata , A. Metherell Louise , Hwa Vivian , L. Storr Helen

Background: Pathogenic IGFI gene mutations causing childhood growth failure are rare. Only 5 autosomal recessive mutations, one IGFI copy number variant and 2 heterozygous frameshift mutations are reported. Heterozygous missense IGFI mutations have not previously been described.Objectives: To identify and functionally characterise a novel missense IGFI variant in a patient with postnat...

An Investigation Of Androgen-responsive Non-coding RNAs In Boys With Atypical Genitalia Without Genetic Variants in the Androgen Receptor (AR)

Alimussina Malika , McMillan Martin , Chudleigh Sandra , D McNeilly Jane , A Diver Louise , McGowan Ruth , S Tobias Edward , Faisal Ahmed S

Introduction: Recent studies point to the existence of androgen-responsive non-coding (nc) RNAs in peripheral blood mononuclear cells (PBMC) RNA.Aim: To quantify the androgen-responsive gene expression of SNORD5 and RNY5 and investigate their relationship to the testosterone (T) rise following hCG stimulation in boys with no genetic evidence of androgen insensitivity.Methods: 19 bo...

SGPL1 Deficiency Leads to Downregulation of Key Enzymes Within the Steroidogenic Pathway

Maharaj Avinaash , Meimaridou Eirini , Williams Jack , Güran Tülay , Braslavsky Debora , Metherell Louise , Prasad Rathi

Background: SGPL1 deficiency is associated with a pathological accumulation of sphingolipid intermediates and a multi-systemic condition incorporating primary adrenal insufficiency. Sphingolipid intermediates such as ceramide, sphingosine and sphingosine 1-phosphate are postulated to act as modulators of the steroidogenic pathway, often acting as second messengers altering downstream expression of steroid responsive transcriptional elements. Ceramide and sphin...
