PAPS synthase 2 is the major PAPS-supplying enzyme for DHEA sulfation

Mueller Jonathan Wolf , Idkowiak Jan , Gesteira Tarsis F , Vallet Cecilia , Hardman Rebecca , van den Boom Johannes , Dhir Vivek , Knauer Shirley K , Rosta Edina , Arlt Wiebke

PAPS (3′-phospho-adenosine-5′-phosphosulfate) synthases provide the cofactor PAPS for all human sulfation pathways. The cytoplasmic sulfotransferase SULT2A1 uses PAPS mainly to sulfate the androgen precursor DHEA (dehydroepiandrosterone). Apparent SULT2A1 deficiency is caused by mutations in the gene coding for PAPSS2; suggesting some form of PAPS synthase-sulfotransferase pairing. Knockdown studies within human adrenocortical NCI-295R ce...

ARID1a, a SWI/SNF subunit, is important for the regulation of a subset of glucocorticoid responsive genes

Stubbs Felicity , Birnie Matthew , Flynn Benjamin , Fang Hai , Biddie Simon , Lightman Stafford , Conway-Campbell Becky

In the clinic, glucocorticoids are widely used due to their anti-inflammatory properties. Despite their huge benefits, prolonged use is often associated with severe side effects as well as the development of glucocorticoid resistance in some cases. Mutations in an important SWI/SNF subunit, ARID1a, have previously been linked to glucocorticoid resistance and are associated with a vast number of human cancers. Determining the functional role of ARID1a...

Intra-adrenal cytokine expression during inflammatory stress is immune-dependent

Fudulu Daniel , Horn George , Hazell Georgina , Angelini Gianni , Lightman Stafford , Spiga Francesca

The hypothalamic-pituitary-adrenal axis is the primary neuroendocrine system activated to establish homeostasis during the stress of critical illness and surgery. However, such critical states also trigger a systemic inflammatory activation that usually precedes the release of adrenocorticotrophic hormone (ACTH) and cortisol. Systemically or locally induced inflammation of the adrenal gland had been described during critical illness. This facilitates...

Development of a liquid chromatography tandem mass spectrometry assay for the profiling of salivary androgens and gestagens

Adaway Joanne E , Schiffer Lina , Arlt Wiebke , Keevil Brian G

Measuring circulating androgen and gestagen concentrations is essential for the diagnosis and treatment monitoring of pathological conditions caused by abnormal steroidogenesis, such as congenital adrenal hyperplasia (CAH) and polycystic ovary syndrome (PCOS). Saliva collection represents a simple and non-invasive technique advantageous for multi sample profiling. We therefore developed a liquid chromatography-tandem mass spectrometry assay for the s...

20β-Dihydrocortisol; a weak endogenous agonist of the glucocorticoid receptor but a potent agonist of the mineralocorticoid receptor

Morgan Ruth , Beck Katharina , Nixon Mark , Homer Natalie , Melchers Diana , Houtman Rene , Meijer Onno , Hadoke Patrick , Odermatt Alex , Keen John , Walker Brian

Cortisol conversion to 20β-dihydrocortisol (20β-DHF) has been reported in many tissues and cells, including skin, muscle, thrombocytes and fibroblasts, although the enzyme responsible is poorly characterised. We have attributed 20β-DHF generation to carbonyl reductase 1 and shown increased activity of this pathway in adipose tissue in obesity in humans, horses and mice. This study addressed the hypothesis that 20β-DHF activates gl...

Improving the therapeutic index of topical anti-inflammatory steroids: angiostatic effects of 5α-tetrahydrocorticosterone vs hydrocortisone

Abernethie Amber J , Maltese Giorgia , Livingstone Dawn EW , Gastaldello Annalisa , Morgan Ruth A , Walker Brian R , Hadoke Patrick WF , Andrew Ruth

Glucocorticoids (GC) have potent anti-inflammatory effects, acting mainly through the glucocorticoid receptor (GR). However GCs have debilitating side effects and a safer alternative is required. 5α-tetrahydrocorticosterone (5αTHB, a metabolite of the natural rodent glucocorticoid corticosterone) may provide a solution: 5αTHB is anti-inflammatory in vivo, effective topically to suppress irritant dermatitis, but with fewer syst...

Salivary cortisol response to the short Synacthen® test provides a reliable alternative to serum measurement in the assessment of suspected hypoadrenalism

El-Farhan Nadia , Tennant Sarah , Lansdown Andrew , Evans Carol , Rees D Aled

Background: Serum total cortisol responses to the short Synacthen® test (SST) are used to confirm or refute a diagnosis of adrenal insufficiency. Salivary cortisol measurement offers a non-invasive alternative and has the potential advantage of evaluating free, bioavailable cortisol. However, reference ranges and its performance in the investigation of suspected hypoadrenalism (SH) have not been firmly established.Aims: 1....

Is renin a useful marker of mineralocorticoid replacement in addison’s disease?

Lyall Marcus , Salem Tarek , Gibb Fraser

The utility of renin measurement in guiding mineralocorticoid replacement is unclear. To address this we retrospectively examined the parameters and treatment of 97 patients with Addison’s disease over a five year period.Methods: Adrenal replacement, blood pressure (BP), orthostatic BP response, urea, sodium, potassium and renin levels of 97 patients attending our clinic were collected over the period 2012–2016. Data ...

Using mouse adrenocortical cell lines to investigate how glucocorticoid synthesis is dynamically regulated

Hazell Georgina , Horn George , Lightman Stafford , Spiga Francesca

Glucocorticoid hormones (cortisol in man, corticosterone in rodent; CORT) are vital for maintaining normal homeostasis in multiple systems ((e.g., the cardiovascular, metabolic, and immune systems), and for an optimal response to acute and chronic stress. Plasma CORT is released from the adrenal zona fasciculata (ZF) in response to circulating levels of pituitary-derived adrenocorticotropin hormone (ACTH). ACTH binds to the MC2-receptor on the membra...

The impact of a point-of-care rapid cortisol assay on success rate, procedural efficiency and radiation dose in adrenal vein sampling for primary hyperaldosteronism

Adam Safwaan , Soares Julian , Lake Ed , Col Caterina Del , Yates Allen , Trainer Peter , Chalmers Nicholas

Introduction: Catheterisation of the right adrenal vein when performing adrenal vein sampling (AVS) is challenging. The AVS Accuracy Kit (AAK) (Trust Medical, Kasai, Japan) enables point-of-care confirmation of accuracy of AVS by rapid cortisol assay. We investigated whether use of AAK during AVS would impact upon procedural success, number of venous samples taken, radiation dose and screening time.Methods: 0.5 ml of each venous blood sample was centrifu...

Does cortisol exposure from the Hydrocortisone day curve predict mortality, type II Diabetes or lipid profiles?

Mourougavelou Vishnou , Choudhury Sirazum , Tan Tricia , Alaghband-Zadeh Jamshid , Bodenham Emma , Meeran Karim , Cegla Jaimini

Background: Hydrocortisone day curves (HCDCs) are commonly used to assess hydrocortisone replacement for patients with adrenal insufficiency (AI).Methods: HCDCs were obtained for 216 adrenally insufficient patients between 2004 and 2012 at Imperial College Healthcare NHS Trust. The area under the curve (AUC) was calculated for each patient’s day profile. Lipid profiles and glycated haemoglobin (HbA1c) values were recorded for each patient at both th...

It’s a matter of time: the emergence of autoimmune polyendocrine syndrome in autoimmune Addison’s disease reaches 100% among those diagnosed more than 50 years ago

White Katherine , Mackay Alick

Addison’s disease (AD) has an estimated prevalence of 126–144 per million among Northern European populations. Average age at diagnosis is 39, but AD may be diagnosed from pre-teens to 80 year olds.AD may occur in isolation or as part of autoimmune polyendocrine syndromes. Previous studies identified significant associations with autoimmune thyroid disease (predominantly hypothyroidism), type 1 diabetes mellitis, vitiligo, vitamin B12 deficienc...

Short synacthen test requests may be reduced by considering test indication and identifying a 9am cortisol value that predicts test result

Wong Christine , Moran Carla

Background: Short synacthen tests (SSTs) are routinely performed for the investigation of adrenal insufficiency (AI), but are costly and time consuming. The frequency of SST testing could be reduced by prioritising testing for specific indications (based on likelihood of failure of the test), and also by identification of an assay-specific 9am cortisol level that obviates the need to proceed to SST.Methods: Retrospective review...

Enteric coating delays the absorption of prednisolone variably and should not be used

Zhang Jennifer , Choudhury Sirazum , Meeran Karim

Once daily oral prednisolone has been shown to mimic the normal circadian rhythm better than other glucocorticoids. Our advice is to take prednisolone first thing on waking and before breakfast to try to mimic the normal circadian rhythm as closely as possible. The leaflet that comes with prednisolone suggests that it should be taken with food. Enteric-coated prednisolone (EC) is believed to be kinder on the stomach, but there is no evidence for its use. We compared EC with st...

How relevant is aldosterone and cortisol co-secretion?

Bhatt Padmanabh Shrikant , Sam Amir H , Salem Victoria , Meeran Karim

Background: Studies suggest that glucocorticoid hypersecretion alongside primary hyperaldosteronism (PA) is common and may contribute to the adverse metabolic phenotype. Adrenal crisis post-surgery for PA is rare.Aim: To determine the prevalence of cortisol co-secretion in PA in patients at Imperial College London NHS Trust, Hammersmith Hospital (a tertiary referral centre for adrenal tumours).Methods: Am...

The potential use of I-131 Norcholesterol scan for large adrenal mass

Alnaim Abdulrhman , Wan Ming Young Simon , Abdel-Aziz Tarek Ezzat , Chung Teng-Teng , Kurzawinski Tom , Bomanji Jamshed

Background: Characterisation of large adrenal lesion is challenging. There is no single robust imaging marker in defining benignity, especially for lesions which are greater than 4cm and are believed to carry increased risk of malignancy.A radiolabelled cholesterol analog tracer, I-131-Norcholesterol (NP-59), localises to adrenal cortical lesions. It has an established role in Conn’s syndrome. It is not expected to concent...

Prednisolone should be first line replacement therapy for adrenal insufficiency

Prabhudev Hemanth , Smith David , Choudhury Sirazum , Meeran Karim

Introduction: We offer patients needing glucocorticoid replacement in primary and secondary adrenal insufficiency the choice of either once daily prednisolone or thrice daily hydrocortisone. A recent European study found no difference between prednisolone and hydrocortisone users in several markers, including glucose, weight, body mass index (BMI), systolic and diastolic blood pressure and waist circumference, although they did suggest an increase in cholesterol and low densit...

Does higher cortisol exposure during hydrocortisone replacement therapy lead to osteoporosis?

Mourougavelou Vishnou , Choudhury Sirazum , Tan Tricia , Alaghband-Zadeh Jamshid , Bodenham Emma , Meeran Karim , Cegla Jaimini

Background: Glucocorticoid-induced osteoporosis is one of the major clinical concerns of long-term steroid treatment. Previous studies have shown that immunosuppressive doses of glucocorticoid can lead to osteoporosis. This study investigated whether there is a relationship between cortisol exposure and the development of osteoporosis in patients receiving replacement doses.Methods: Hydrocortisone day curves (HCDCs) performed a...

How accurate are urinary metanephrines in screening for phaeochromocytoma?

Walsh Joseph , Spence Kirsty , McDonnell Margaret , Graham Una

The Endocrine Society recommends urinary or plasma metanephrines as first choice screening tests for phaeochromocytoma due to their high sensitivity. Test specificity is limited by the influence of many commonly prescribed medications resulting in false positive results and additional investigations. The aims of this retrospective study were to (1) Determine the diagnostic accuracy of urinary metanephrines using current cut-off values and (2) Evaluat...

Clinical implications of the short synacthen test: an audit of its rational use in the assessment of adrenocortical insufficiency

Stratos Efstratios , Likhari Taruna , Sharma Sanjeev

Aims: The short synacthen test (SST) is considered as the gold standard test to assess the viability of the hypothalamic-pituitary-adrenal axis. This study explores the appropriateness of its clinical use in a district general hospital. Furthermore, it assesses the effectiveness of the alternate use of 9AM cortisol in excluding hypoadrenalism and the cost-effectiveness of sampling both 30 and 60 minutes serum cortisol in SST.Me...

The effect of 4,4′ DDT, 4,4′ DDE, 4,4′ DDD, and 2,4′ DDD on dihydrotestosterone binding to and releasing from the androgen receptor

Resto Tahyra , Chavez Amanda , Flores Ventura , Dean Frank

The androgen receptor (AR) is required for the development of the male phenotype and traits. Some compounds, including diphenylethers and diphenylamines, inhibit AR activity by binding to a surface cleft named binding function 3 (BF-3). Such inhibitors bind by hydrophobic interactions between the two phenyl groups and the BF-3 site. A similar diphenyl group structure is found in 4,4′ DDT, 4,4′ DDE, 4,4′ DDD, and 2,4′ DDD, whic...

Quality of life in patients with adrenal disease: a systematic review

Ho Winnie , Druce Maralyn

Evaluating patients with adrenal disease is uniquely challenging as biochemical parameters for assessing disease control or adequacy of hormone replacement are imprecise or lacking. QOL measures are increasingly being used to assess patients with adrenal disease, using a range of generic and disease specific measures. Reduced quality of life has been observed in patients with adrenal disease, even when biochemical cure is possible. We performed a sys...

A comparison between short synacthen and long synacthen results in clinical decision making

Hegde Pallavi , Bawa Fareha , Sharma Dushyant , Purewal Tejpal

Introduction: Traditionally the long synacthen test (LST) is used in some centres to assess hypothalamic/ pituitary and adrenal (HPA) axis. Evidence that it offers advantage over short synacthen test (SST) is lacking. Whilst changing our local protocol we evaluated 27 patients who had both tests in our trust. We compared the impact of the results in clinical decision making.Results: Mean age was 53 years. The indications for th...
