Replication of association at the LPP and UBASH3A loci in a UK autoimmune Addison’s disease cohort

Howarth Sophie , Sneddon Georgina , Allinson Kathleen , Razvi Salman , Mitchell Anna , Pearce Simon

Background: Autoimmune Addison’s disease (AAD) is a rare endocrinopathy arising from a complex interplay between multiple genetic susceptibility polymorphisms and environmental factors. Several variants in immune pathways have been identified through hypothesis-driven candidate gene analysis, though these associations can prove difficult to replicate. The first genome wide association study (GWAS) with patients from Scandinavian Addison’s registries identified associ...

Identification and characterization of a receptor for N-terminal pro-opiomelanocortin peptide

Alshammari Fatema , Bicknell Andrew , Lander Elizabeth

Background: Numerous studies have reported the role of the N-terminal of pro-opiomelanocortin (N-POMC1-76) and its smaller fragments; 1-28 and 1-49, in adrenal steroidogenesis and mitogenesis. A full understanding of this area will help to understand the pathophysiology of certain adrenal tumours but exactly how these peptides elicit this effect is unclear. We have recently identified an orphan G protein-coupled receptor (GPCR) as a possible N-POMC receptor. Preliminary data s...

Gender-Related Analytical Bias in Biochemistry - Under-Recovery in a Serum Cortisol Immunoassay

Chipchase Allison , Hall Sebastian

Background: The displacement of cortisol from its binding globulin (CBG) in the Abbott Alinity immunoassay assumes an average concentration of CBG in all individuals. Displacement buffer volume, and/or composition, is frequently insufficient to displace cortisol where higher concentrations of CBG are present (e.g. with higher oestrogen concentrations). To address this bias, the Eastern Pathology Alliance (EPA) introduced a 1:2 dilution step on all serum cortisol specimens in D...

Inflammation-Based Scores as Predictors of Treatment Response in Advanced Adrenocortical Carcinoma

Mangone Alessandra , S. Elhassan Yasir , Prete Alessandro , Asia Miriam , Detomas Mario , Altieri Barbara , Mantovani Giovanna , Ronchi Cristina L.

Background: Standard treatment for advanced adrenocortical carcinoma (ACC) is mitotane in monotherapy or combined with etoposide, doxorubicin and cisplatin (EDP), yet biomarkers predictive of treatment response are lacking. Inflammation-based scores were proposed as predictors for gemcitabine+capecitabine efficacy, used as second-line in progressive ACC. We investigated the role of inflammation-based scores in predicting response to first-line treatment in advanced ACC.<p ...

Development of novel immunoassays for pro-opiomelanocortin (POMC)-derived peptides as surrogate markers of adrenocorticotrophin levels for use in the diagnosis of Cushing’s syndrome

Donnelly Megan , Lowry Philip , Gibbins Jon , Bicknell Andrew

Plasma adrenocorticotrophin (ACTH) is extremely labile and far from an ideal analyte for use in the diagnosis of Cushing’s syndrome. Processing of ACTH by some ectopic tumours releases high levels of smaller ACTH-like fragments, α-MSH and CLIP, which can interfere with individual antibodies in current diagnostic immunoassays. Furthermore, cross-reactivity with the precursor of ACTH, pro-opiomelanocortin (POMC), increases the likelihood of erroneous interpretations an...

Factors which contribute to LDL-C target attainment in familial hypercholesterolaemia

Vineall Owen , Jones Ben , Cegla Jaimini , David Alessia

Background: In the UK, NICE guidelines for familial hypercholesterolaemia (FH) recommend a greater than 50% reduction in low-density lipoprotein-cholesterol (LDL-C) as the therapeutic target. However, despite the availability of a range of lipid lowering medication, this target is often difficult to achieve and, more importantly, maintain life-long. Understanding factors that affect LDL-C target achievement is key to reducing cardiovascular disease (CVD) risk. Currently, there...

Involvement of the adrenal gland in post-bariatric surgery Type 2 Diabetes remission

Doria Durazzo Isabella , F. Brisnovali Niki , Akalestou Elina

Currently, most Type 2 Diabetes (T2D) treatments are targeted for the mitigation of the disease rather than remission. It has been previously demonstrated that T2D remission post-bariatric surgery in mice is independent of weight loss, indicating a metabolic mechanism. One avenue that remains largely unexplored is the role of cortisol, a hormone secreted from the adrenal cortex, dysregulation of which is linked to insulin resistance and obesity. The enzyme 11β-Hydroxyster...

Can we use swabs to collect samples for salivary androgen analysis?

Adaway Joanne

Salivary androgens (testosterone, androstenedione, 17-hydroxyprogesterone, 11-ketotestosterone and 11-hydroxyandrostenedione) are currently analysed on samples collected by passive drool. Other saliva analyses such as cortisol are often collected using swabs such as Sarstedt Salivettes, therefore multiple samples are required if both cortisol and androgen analysis is requested. The aim of this study was to determine whether salivary androgen analysis could be performed on samp...

Adrenal reserve and glucocorticoid requirements post unilateral adrenalectomy for primary aldosteronism

Bakaya Kaushiki , Bharadwaj Aniket , Chung Teng-Teng

Introduction: Primary aldosteronism (PA) is the most common cause of secondary hypertension that can be cured by surgery. Mild autonomous cortisol co-secretion is a recognised feature of PA, which is associated with an increased cardiometabolic penalty and the possibility of adrenal insufficiency postoperatively. There have also been case reports of adrenal crisis post adrenalectomy for this patient subtype. We report our experience of adrenal insufficiency post adrenalectomy ...

Sulfasalazine as a cause of false positive elevation of normetanephrine in patients with adrenal mass – A diagnostic challenge

Ter Zuling Eunice , Balasubramanian Sabapathy

In clinical settings, when biochemical screening revealed grossly elevated urinary normetanephrine and metanephrine in the presence of an adrenal mass, there is a high clinical suspicion of a pheochromocytoma. However, sulfasalazine, an anti-inflammatory drug can cause analytical drug interference, leading to falsely positive elevation of urinary normetanephrine and a misdiagnosis of phantom pheochromocytoma. This report illustrates two patients with adrenal mass who had false...

Preliminary data from FABULAS: a Feasibility study of RadioFrequency endoscopic ABlation, with ULtrasound guidance, as a non-surgical, Adrenal Sparing treatment for aldosterone producing adenomas

Argentesi Giulia , Wu Xilin , Goodchild Emily , Laycock Kate , Ney Alexander , Senanayake Russell , MacFarlane James , Goodchild George , Wilson Patrick , Godfrey Ed , Gurnell Mark , Cheow Heok , P Pereira Stephen , M Drake William , J Brown Morris

Primary aldosteronism (PA) is the potentially curable cause of high-risk hypertension in 5-10% of unselected patients. Diagnosis and lateralisation of PA is challenging and complex. Outcomes post total adrenalectomy, the standard treatment for unilateral aldosterone producing adenomas (APAs), are variable. Between 30-60% are cured (1), but prediction of outcome is unreliable, and some patients are reluctant to have abdominal surgery to remove a whole adrenal gland. Endoscopic ...

HLA-DRB1*0404 is associated with the deletion of the 21-hydroxylase pseudogene in AAD patients

Mavridou Maria , Mitchell Anna , Allinson Kath , Lane Laura , Pearce Simon

Background: HLA-DRB1*04 is one of the MHC alleles which is associated with several autoimmune endocrinopathies, including autoimmune Addison’s disease (AAD). The two versions of the gene which encodes the main target of the autoimmune attack in AAD, steroid 21-hydroxylase, are encoded in a gene cluster, called RCCX module, which is a copy number variation located in the MHC class III locus. Previous data from our group showed that AAD patients are more likely to have no c...

Whole genome sequencing and Sanger sequencing to identify novel mutations in adrenal tumours from cats with primary hyperaldosteronism

Watson Alice , Syme Harriet , Brown Morris

Primary Hyperaldosteronism (PA) is caused by adrenal tumours or bilateral adrenal hyperplasia (Djajadiningrat-Laanen et al., 2011) causing constitutive aldosterone production. Both germline and somatic mutations have been identified in human PA (Scholl, 2022). The commonest somatic mutations in benign tumours causing PA in humans include KCNJ5, CACNA1D, ATP1A1 and ATP2B3 (Williams et al., 2015). It is hypothesized that analogous somatic mutations arise in fel...

Depleting NAD+ pools specifically in the endoplasmic reticulum lumen impairs 11β-hydroxysteroid dehydrogenase activity

Kabli Ali , Heising Silke , Heaselgrave Samuel , Elhassan Yasir , Hardy Rowan , Stromland Oyvind , Ziegler Mathias , Morgan Stuart , Hodson David , Lavery Gareth

Introduction: The endoplasmic reticulum (ER) lumen enzyme 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) obtains NADPH from hexose-6-phosphate dehydrogenase to reduce cortisone to the active glucocorticoid cortisol. Cells depleted in NAD+ (parent molecule of NADPH) have impaired 11β -HSD1 activity, which can be rapidly rescued with supplementation of the NAD+ precursor nicotinamide riboside. This suggests the existence of an ER-specific pathway to NAD(P)(H)....

Salivary dexamethasone and 11-dehydrodexamethasone analysis post overnight dexamethasone suppression test

Marshall David , Keevil Brian , Issa Basil

Background: The 1 mg overnight dexamethasone suppression test (ONDST) is recommended as a first-line test for the investigation of Cushing Syndrome. Measurement of dexamethasone alongside cortisol in a 9am serum sample has been credited with improving diagnostic sensitivity of the test. Previous studies have also looked at the utility of salivary dexamethasone and have observed poor correlation with serum dexamethasone. Herein we introduce the concept of measuring 11-dehydrode...

Mapping the chromatin-associated-lncRNAs and their enhancer regions between lymphatic and endothelial cells

Mitic Tijana , Chaloner Emma , Zhang Chenyun , Dudnakova Tatiana , Dunn-Davies Hywel

Blood vessels supply nutrients, oxygen and other key molecules necessary for the function of all organs in the body. The endothelial cell (EC) repair and response to injury or hypoxia is also regulated by the interplay of chromatin-modifying enzymes. Likewise, dysregulation of the lymphatic system underlies the development of the metabolic syndrome. New technologies using omics approaches have now allowed the detection of chromatin and RNA molecules that directly interact in n...

Prednisolone replacement therapy in Adrenal Insufficiency: Defining target ranges and timing for optimum Prednisolone level sampling

Sharma Angelica , Lazarus Katharine , Choudhury Sirazum , Meeran Karim

Introduction: Glucocorticoid replacement in adrenal insufficiency may be achieved by administering thrice- daily hydrocortisone or once-daily very low dose (2-4 mg) prednisolone. Prednisolone’s longer half-life enables once-daily dosing, improving patient satisfaction and compliance. At very low doses, it has shown no difference in most markers of metabolic risk when compared with hydrocortisone. At Imperial College Healthcare NHS Trust (ICHNT), use of an eight-hour troug...

Validating the cholesterol-year-score as a predictor of major cardiovascular events in familial hypercholesterolaemia

Vineall Owen , Jones Ben , David Alessia , Cegla Jaimini

Background: Cardiovascular disease (CVD) risk in familial hypercholesterolaemia (FH) is driven by cumulative exposure to high low-density lipoprotein cholesterol (LDL-C) levels. Previously, LDL-C burden has been loosely approximated using the cholesterol year score (CYS) based on two LDL-C readings only. We aimed to determine whether a more sophisticated LDL-C burden score based on serial LDL-C measurements, could more accurately predict major atherosclerotic cardiovascular ev...

Neonatal salt wasting: A rare case of X-linked adrenal hypoplasia congenita

Frank Amy R , Longmuir Sophie , McNeilly Jane , McGowan Ruth , Faisal Ahmed S , Smith Karen

Neonatal salt wasting can present in neonates with a life-threatening state of hyponatraemia, hyperkalaemia, dehydration and metabolic acidosis. The differential diagnosis of neonatal salt wasting includes congenital adrenal hyperplasia (CAH) most commonly due to 21-hydroxylase deficiency, pseudohypoaldosteronism (PHA), X-linked adrenal hypoplasia congenital (AHC) and aldosterone synthase defects. Diagnostic work up should include serum measurement of ACTH, Cortisol, 17OH-prog...

Mapping corticosteroids in mouse kidney following changes in dietary salt intake using mass spectrometry imaging

Stasinopoulos Ioannis , Khan Shazia , MacKay Logan , Brown Roger , Bailey Matthew , Andrew Ruth

Blood pressure homeostasis is regulated via renal sodium reabsorption by aldosterone and glucocorticoids, although the role of glucocorticoids is less clear. High-salt diets lead to suppression of aldosterone in plasma, but changes in available ligands for the mineralocorticoid and glucocorticoid receptors in kidney subregions are unknown. Hypothetically, high-salt intake modifies aldosterone and corticosterone amounts in specific kidney subregions. Kidney cryosections from ma...

Screening for adrenal insufficiency using home waking salivary cortisone is accurate and lowers NHS costs

Debono Miguel , Elder Charlotte , Lewis Jen , Jacques Richard , Caunt Sharon , Fearnside Jane , Dixon Simon , Newell-Price John , Whitaker Martin , Keevil Brian , Ross Richard

Introduction: The 250µg Short Synacthen test (SST) is the reference standard for a diagnosis of adrenal insufficiency (AI) in most endocrine centres. The test is expensive and time consuming, requiring clinic attendance. We hypothesised that a cheaper home waking salivary cortisone (WSC) is predictive of the SST 30-minute cortisol >430 nmol/l cut-off and carried out a diagnostic accuracy study to assess the predictive value of the WSC in diagnosing and excluding AI. W...

Using mass spectrometry imaging to study the lipidome of atherosclerotic plaques

Ntshangase Sphamandla , Khan Shazia , Kaczynski Jakub , Newby David , Hadoke Patrick , Andrew Ruth

Atherosclerotic cardiovascular disease (ASCVD) is a chronic inflammatory disorder characterised by the gradual build-up of plaques in the arterial wall. Unstable plaques are more dangerous than stable plaques as they are prone to rupture and obstruct blood flow, resulting in heart attacks and strokes. Lipids play a key role in plaque progression, yet their exact involvement remains elusive. We hypothesise that stable or unstable plaques will have distinct spatial lipid phenoty...

The importance of questioning the ACTH result in Cushing’s and potential need for a two-site assay

Hart Dulciana , Arya Aditi , Levy Miles J

This case shows the potential unreliability of a single ACTH assay in the context of Cushing’s syndrome and need for better ways of measuring ACTH and precursors. A 35 year-old lady presented with severe abdominal pain and cushingoid features. CT scan showed a 2.9 cm right adrenal nodule. Investigations: 24-hour UFC 446 nmol/l, post-dexamethasone cortisol level of 572 nmol/l. The referring hospital found a suppressed ACTH < 0.1ng/l consistent with ACTH-independent Cus...

Prednisone is 100% converted to Prednisolone by first pass metabolism

Chia Eng Pei , Lazarus Kate , Narula Kavita , Choudhury Sirazum , Tan Tricia , Meeran Karim

Prednisolone is widely prescribed in the UK, whereas prednisone is used instead for the same indications in the United States. Both have utility as anti-inflammatory agents and for use as glucocorticoid replacement therapy at lower doses. Oral prednisone is converted to prednisolone by first pass hepatic metabolism by 11 beta HSD-1. This study was undertaken to compare the bioavailability of prednisone against prednisolone. To determine the conversion of prednisone to predniso...

Prolonged adrenal suppression does not always need additional glucocorticoid therapy

Narula Kavita , Lararus Kate , Meeran Karim , Tan Tricia

A 53 year old female weighing 117 kg was thought to be slightly cushingoid by her GP who checked a morning cortisol. This was surprisingly undetectable (<28nM) on 13th June 2022. The patient was urgently referred for a medical opinion. A repeat cortisol in A&E was 29nM with an undetectable ACTH. Given the lack of clinical features of adrenal failure, further history was obtained. The patient appeared well on examination, and denied any inhaled, oral/ topical steroid us...
