Characterisation of Type 2 Diabetes mellitus in children and young people across 2 large tertiary Paediatric Diabetes centres

Chatterjee Sumana , Baioumi Alaa , Pryce Rebekah , Williams Georgina , Giri Dinesh

Introduction: The prevalence of paediatric Type 2 diabetes (T2DM) is increasing, contributed by rising incidence of obesity worldwide. Paediatric T2DM is a progressive disease with increased risk of complications and morbidities. Despite recent research, many aspects such as its pathophysiology and optimal management remain unknown.Aim: To characterise the cohort of T2DM patients across 2 large tertiary paediatric diabet...

Age at diagnosis of XLH amongst children with and without a family history: Findings from the International XLH Registry

Uday Suma , Sandilands Kerry , Williams Angela , Mughal M.Zulf

Background: X-linked hypophosphatemia (XLH) is a rare, progressive, genetic phosphate wasting disorder leading to rickets, lower limb deformities as well as short and disproportionate stature. The condition is inherited in the majority, however spontaneous mutations are reported in ≈30% of cases. Its rarity, coupled with its diverse clinical manifestations, may lead to delayed diagnosis and subsequently delayed treatment initiation. The objective of this an...

FADES: A Birth Cohort to Understand the Mechanisms Underlying Accelerated Onset of Autoimmunity in Children with Down's Syndrome

Williams Georgina , Mortimer Georgina L. , Leary Sam D. , Williams Alistair J.K. , Gillespie Kathleen M. , Hamilton - Shield Julian P.

Background and Aims: Children with Down's syndrome (DS) are at increased risk of autoimmune conditions including type 1 diabetes (T1D), coeliac and thyroid disease. We previously examined the clinical and immunogenetic characteristics of these conditions in children with DS. An earlier age-of-onset of diabetes was observed compared with children with T1D from the general population despite having decreased frequencies of the established genetic susceptibil...

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 ...

Sphingosine-1-Phosphate Lyase (SGPL1) Deficiency is Associated with Mitochondrial Dysfunction

Maharaj Avinaash , Bradshaw Teisha , Williams Jack , Guran Tulay , Braslavsky Debora , Brugger Britta , Metherell Lou , Prasad Rathi

Background: Loss of function mutations in SGPL1, a key component of sphingolipid metabolism, are associated with accumulation of sphingolipid intermediates giving rise to a multisystemic disease incorporating primary adrenal insufficiency (PAI) and progressive renal and neurological disease. Sphingolipids are implicated in mitochondrial apoptosis via induction of mitochondrial outer membrane permeabilization, cytosolic release of inter-membranal cytochrome c and activ...

Early Onset Hypertension with Primary Hyperaldosteronism through Mutation in the Calcium Channel CACNA1H – Case Report

Dumitrescu Cristina , Chirita Corina , Procopiuc Camelia , Gherlan Iuliana , Olaru Maria , Lifton Richard P , Nelson-Williams Carol

Background: The genetic causes of primary hyperaldosteronism are still being discovered.Results: We present the case of a 17-years-old girl who was found by accident with severe hypertension (TA 180/100 mmHg, bilateral). Her personal history was unremarkable. Her father had hypertension and a paternal aunt had died at 55 due to a stroke. Both her sisters and mother had normal blood pressure. The cardiological examinationshowed concentric left ventricle h...

Androgen Profile Differs to Adults in Adolescent Girls with Polycystic Ovary Syndrome

Frerichs Carley , Das Urmi , Garden Ann , Williams Cara , Dharmaraj Poonam , Didi Mohammed , Ramakrishnan Renuka , Blair Jo

Background: Diagnostic criteria for polycystic ovarian syndrome (PCOS) are well established in the adult population, but may not be appropriate for adolescent girls. Clinical and/or biochemical hyperandrogenism is one important diagnostic criterion. Screening for hyperandrogenism is often restricted to measurements of testosterone in adult practice. It was our impression that this strategy would under-diagnose PCOS in our adolescent population.Objective ...

A novel case of hypoglycaemia secondary to a pro-insulin processing disorder

Amin Nadia , Wark Gwen , Church David , Burling Keith , Barker Peter , Williams Gemma , O'Rahilly Stephen

Background: Hypoglycaemia in patients with a high concentration of insulin and low concentration of C-peptide can be secondary to administration of exogenous insulin. This often results in safeguarding measures, with significant consequences for the patient and family. We report a novel case of a patient with symptomatic hypoglycaemia. Initial results suggested high insulin and low C-peptide levels, but subsequent testing revealed a pro-insulin processing diso...

Puberty and Gonadal function in Wolfram Syndrome: A retrospective single centre study

Cunningham Olivia , Newell Laura , McCarthy Liam , Williams Denise , Barrett Timothy , Dias Renuka

Background: Wolfram Syndrome (WS) is a rare progressive neurodegenerative disorder characterised by early-onset diabetes and optic atrophy as well as a variable spectrum of other clinical features. It is caused by mutations in the WFS1 gene. There is currently limited published literature on pubertal progression and gonadal function in WS.Aims: To review the gonadal function and pubertal progression of a cohort of adoles...

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...
