Unravelling the role of epigenetics in reproductive adaptations to early-life environment

Melamed Philippa

Adult reproductive function is affected by early life environments and experiences, pointing to a possible role for epigenetic modifications in directing an adaptive response. Using mouse and cellular models, we have been studying the mechanisms underlying the shorter reproductive lifespan experienced by Bangladeshi women who grew up in Bangladesh as opposed to the UK, a phenotype associated specifically with the greater immune challenges in Bangladeshi childhood and altered D...

Heterozygous CYP11A1 Mutation Associated with 46XY Disorder of Sexual Differentiation and Mild Adrenal Insufficiency

Bowen Philippa , Nicoll Nicky , Giri Dinesh

Background: CYP11A1 encodes the P450 side chain cleavage (scc) enzyme. This protein localises to the mitochondrial inner membrane and catalyses the conversion of cholesterol to pregnenolone which is the first and rate-limiting step in the synthesis of all steroid hormones. P450scc deficiency is a rare disorder that can present as adrenal insufficiency and varying degrees of disorder in sex development (DSD) in 46XY individuals. Typically, this disorde...

Mosaic PHEX variants are important causes of X-linked hypophosphataemic rickets.

Prentice Philippa , Owens Martina , Brain Caroline , Allgrove Jeremy , Gevers Evelien ,

Introduction: X-linked hypophosphataemic rickets (XLH), due to mutations in the PHEX (Phosphate-regulating Endopeptidase homolog; X-linked) gene, causes reduced bone and dentin mineralisation and decreased renal phosphate reabsorption. Mosaic PHEX mutations are reported only in a few case reports.We report three male cases, with mosaic pathogenic PHEX variants, showing importance of considering this in the diagnosis of XLH.Case 1 pre...

Outmoded by Mody? A Case Report of HNF1A-Mody in Paediatric Stroke

Siese Thomas , Hickingbotham Hannah , Eggers Anne , Alins-Sahun Yolanda , Bowen Philippa , Hamilton-Shield Julian

Background: The association between HNF1A-MODY and vascular complications including stroke has previously been identified in adults but to date there have been no reported paediatric cases published.Description: We present the case of an Eritrean 13-year-old girl, who was admitted with an acute ischaemic stroke, on a background of Diabetes Mellitus (Presumed Type 1) diagnosed the previous year. Aside from being on multip...

Project to improve paediatric post-neurosurgical fluid management and to reduce the risks associated with Diabetes Insipidus (DI), Syndrome of Inappropriate ADH (SIADH) and Cerebral Salt Wasting (CSW).

Miller-Molloy Felix , Saxena Shreya , Bowen Philippa , Fellows Greg , Crowne Liz

Background: Complex fluid balance problems are well established post-neurosurgery and traumatic brain injury (TBI). The triple-phase response requires fluid management strategies reactive to urine output as patients shift between DI and SIADH. Prevalence of CSW is controversial; but ensuring sodium homeostasis is central to safe fluid management. To improve clinical care for these complex patients an audit of existing institutional guidelines was undertaken. N...

Recent Secular Change in Pre- and Postnatal Growth and Adiposity in Infants of Mothers with Gestational Diabetes

Olga Laurentya , Prentice Philippa , Hughes Ieuan , Acerini Carlo , Ong Ken , Dunger David

Objective: Typically, infants born to mothers with gestational diabetes mellitus (IOGDM) have greater risks for macrosomia, later obesity and metabolic diseases. However, we have noticed that birth weights of IOGDM have reduced over the last decade even with uniform application of the International Association of Diabetes and Pregnancy Study Group’s (IADPSG) consensus definition. We therefore compared infancy growth outcomes from two IOGDM cohorts born during non-overlapp...

Complexities in the Management of New-Onset Diabetes after Transplantation (Nodat) in an Adolescent with Senior-Loken Syndrome

Bowen Philippa , Garde Alison , Adams Rebekah , Velleman Sophie , Inward Carol , Giri Dinesh

Background: New-Onset Diabetes after Transplant (NODAT) is a well characterized entity in adult population but less described in paediatric and adolescent population. The development of NODAT is associated with reduced graft function. The consensus for its management is largely available for adult population with a lack of specific guidelines applicable to the paediatric population.Case: A 16-year-old patient with an established renal failure and visual ...

Infancy Lipidomic Analyses and Associations with Early Nutrition and Growth

Prentice Philippa , Koulman Albert , Matthews Lee , Acerini Carlo , Ong Ken , Dunger David

Background: Links between early life exposures and long-term health outcomes may in part be due to nutritional programming, and suggested benefits of breast feeding during infancy include reduced risk of obesity and metabolic disease. Mechanisms remain unexplained but potential differences in lipid exposures during infancy may be involved.Objective and hypotheses: To explore the effects of breast- or formula-feeding on lipidomic profiles we used recently...

Novel Severe Skeletal Dysplasia with Under-Mineralisation Associated with Reduced In Utero Calcium Transport and TRPV6 Compound Heterozygous Variants

Bowen Philippa , Caswell Richard , Castle Bruce , Welch C Ross , Hilliard Tom , Smithson Sarah , Ellard Sian , Burren Christine

Background: Fetal skeletal bone development and mineralisation depends on placental calcium transfer. Although Parathyroid Hormone (PTH) pathway has some contribution, TRPV6 (the sixth member of the Transient Receptor Potential Vanilloid family) is a recently identified receptor involved in calcium transport and is predominantly expressed in the placenta. It has not previously been linked with skeletal development disorders.Case: This infant had...

Efficacy and safety profile of recombinant insulin like growth factor 1 (rh IGF1) therapy: A long term follow up study at a single tertiary centre.

Aftab Sommayya , Prentice Philippa , Katugampola Harshini , Tollerfield Sally , Atterbury Abigail , Shah Pratik , Peters Catherine , Gevers Evelien , Dattani Mehul ,

Background & Objective: Recombinant human insulin like growth factor 1 (rhIGF1) therapy is the only treatment available for primary IGF1 deficiency and related disorders. However, it’s efficacy in promoting growth is controversial and needs cautious monitoring for adverse effects. The aim of this study was to determine the long-term efficacy and safety profile of rhIGF1 therapy.Methods: Retrospective review of a...
