7 Distance Covering 1,727,000 square kilometres, it is Australia s second largest State. It represents more than a quarter of the country s total area with a current population of over three million people. To put Queensland in perspective, it s more than seven times the size of the United Kingdom, more than four and half time the size of Japan, around six and half times the size of New Zealand, more than five times the size of Texas.

9 2. Glucorticoid Production
10 Any of a group of steroid hormones, such as cortisol, that are produced by the adrenal cortex, are involved in carbohydrate, protein, and fat metabolism, and have anti-inflammatory properties
11 Adrenal glands
12 Adrenal glands Functionally consist of three tissues under independent control. Outer cortex (ZG), mainly controlled by the reninangiotensin system regulates release of aldosterone (sodium homeostasis). Inner cortex (ZF&R), mainly controlled by the CRH - ACTH system regulates the responses to stress via the actions of cortisol. Also produces adrenal androgens. Medulla, which is part of the sympathetic nervous system produces adrenaline & noradrenaline.

21 CUSHING S SYNDROME large group of signs and symptoms chronic exposure to excessive concentrations of glucocorticoids challenging diagnosis Adrenal tumour, Pituitary tumour (ACTH) or Ectopic ACTH production

25 4. Testing and Diagnosis
26 Diagnosis Disease suggested by signs and symptoms Many non-specific None are truly characteristic of Cushing s Must confirm findings with biochemical tests Medications Glucocorticoids injested, inhaled, topical Factitious
27 Cortisol Assay 1 Tandem mass spectroscopy gold standard method lab logistical issues assay frequency, availability of instrumentation Immunoassay readily available for cortisol assay issues cross-reactivity, binding protein interference Random access and run 24/7
28 Cortisol Assay 2 Other issues biological variability diurnal variation plus episodic secretion total vs free >95% circulates bound to CBG and albumin nonactive free - biologically active
29 Recommendations for Initial Testing Urinary Free Cortisol (UFC) x 2 ~midnight salivary cortisol 1 mg o/n dexamethasone suppression test (DST) Longer low-dose DST (2 mg/d for 48 hrs. Extended Liddles test
30 Adrenal Insufficiency (Addison s disease) tiredness, weakness, lethargy anorexia, nausea, vomiting weight loss BP, postural hypotension, dizziness loss of body hair pigmentation
31 Conclusion Syndromes due to cortisol excess or deficiency cause significant morbidity and mortality and may be difficult to diagnose. Modulation of hypothalamic-pituitary-adrenal feedback with synthetic hormone analogues is often required for diagnosis. Synacthen is most commonly used to stimulate the HPA axis and dexamethasone to suppress.
32 5. Overview of UPLC MS/MS Method

34 Clinical states requiring multianalyte analysis Metyrapone Cortisol and 11 deoxycortisol Cushing s Sydrome Cortisone and Cortisol Congenital Adrenal Hyperplasia (CAH) Cortisol and 11 deoxycortisol Dexamethasone Suppression Test Cortisol and Dexamethasone Fictious Cushing s Syndrome Cortisol, Cortisone, Prednisolone, Methyl Prednisolone and Dexamethasone
35 Advantages of UPLC MS/MS Multi component analysis Sensitivity (LOQ < 1nmol/L) Small sample volume (200 ul) Minimal sample prep, commonality across matrices High throughput (Cycle time 4 min) Specificity
36 Sample preparation 1 Plasma total steroids Incubated with 1M HCl for 15 min to release from binding proteins Plasma free steroids Ultrafiltration under temperature controlled conditions Urine Saliva
37 Sample preparation 2 200ul sample + Internal standards + water Extracted using 50mg bed OASIS HLB SPE columns Washed and eluted with ethyl acetate Dried under air and reconstituted in Mobile phase Inject 20ul
