Background: Registries are of key importance for a centre of expertise. Endo-ERN consists of 71 reference centres (RCs) that cover several groups of rare endocrine conditions within 8 themes ( It is unclear if awareness, participation and availability of registries is uniform for all conditions within Endo-ERN.Objective: To determine the extent of engagement in registries of Endo-ERN members.<p cl...

National UK Guidelines for the Clinical Assessment, Diagnosis, Treatment and Follow-up of Children and Young People (CYP) Under 19 Years of Age with Phaeochromocytoma (PCC) and Paraganglioma (PGL) – On Behalf of the UK Paediatric Phaeochromocytoma and Paraganglioma Guideline Development Group (GDG)

Background: PCC and PGL are rare in CYP. National children’s registry data reveal an annual incidence of 0.2 and 0.3 per million in 5–9 and 10–14 year age groups respectively. Almost all result from a genetic predisposition, can present with non-specific symptoms, and represent a significant management challenge.Aims: We aimed to provide the first interdisciplinary national management guidelines using the AGREEII framework for CYP with con...

Regulation of Salt, Sugar and Sex Steroids in Humans by Genetic Variations in NADPH Cytochrome P450 Oxidoreductase (POR) Identified in 1000 Genome Samples

Pandey Av Amit V , Udhane Sameer S , Parween Shaheena

A broad spectrum of human diseases, including abnormalities in steroidogenesis, are caused by mutations in the NADPH cytochrome P450 oxidoreductase (POR) (1-4). Human POR is a diflavin reductase that transfers electrons from NADPH to small molecules, non-P450 redox partners and cytochrome P450 proteins in the endoplasmic reticulum. Cytochrome P450 proteins perform a very wide range of reactions, including metabolism of steroids, drugs and other xenobiotics. Therefore, genetic ...

Glucocorticoid Deficiency Causes Differentially Dysregulated Oxidative Stress Depending on the Steroidogenic Defects

Li Nan , Weger Meltem , Griffin Aliesha , Eachus Helen , Cunliffe Vincent T , Krone Nils

Glucocorticoids regulate a wide range of biological processes including metabolism. Patients with adrenal insufficiency show impaired glucocorticoid biosynthesis either caused by adrenal defects (primary adrenal insufficiency) or by defects in the pituitary gland or hypothalamus (secondary or tertiary adrenal insufficiency). The systemic consequences of differentially disrupted steroid hormone biosynthesis remain unclear. Increasing evidence suggested steroid hormone precursor...

Pubertal Females Produce an Enhanced Interferon-Alpha, Anti-viral Response Compared to Males, Which is Associated with X Chromosome Number, and Not Sex Hormones

Webb Kate , Butler Gary , Ciurtin Coziana , Peckham Hannah , Radziszewska Anna , Wedderburn Lucy R , Ioannou John

Introduction: Very little is known about the development of the immune system during puberty. Autoimmune diseases, like juvenile onset systemic lupus erythematosus (jSLE), have an unexplained female bias and a higher incidence after puberty. IFN alpha (IFNα) is a potent antiviral cytokine, and jSLE has a strong IFNα transcriptional signature. Toll like receptors 7 and 9 (TLR7/9) sense viral RNA and DNA respectively, and trigger plasmacytoid dendritic cells (pDC) to p...

Sex Differences in Autoimmune Disease: Testosterone is Associated with a Decrease in Expression of Key Anti-viral Genes During Puberty, Which may Decrease the Risk of Autoimmunity in Males

Webb Kate , Butler Gary , Ciurtin Coziana , Peckham Hannah , Radziszewska Anna , Wedderburn Lucy R , Ioannou Yiannis

Introduction: There are well described sex differences in the immune system. It has been shown in both innate and adaptive immunity that females have a more robust response than males. Various autoimmune diseases have a strong sex bias towards females. It is the accepted dogma that oestrogen in females relates to an increased risk of autoimmunity, but evidence to this end is scarce. Interferon alpha (IFNα) is a potent anti-viral innate cytokine, and many autoimmune diseas...
