Dx - assess cortisol excess, determine if pathologic, and ACTH-dependence: Cortisol excess - see if 24 hr urine cortisol > 100. Pathologic excess - low-dose dexamethasone should suppress cortisol… won’t if diseased. ACTH dependence - is ACTH normal/high (ACTH-dependent), or low (ACTH-independent)

Cortisol is Important in Resisting Stress & Inflammation. Almost any type of stress, whether physical or neuro- genic, causes an immediate and marked increase in ACTH secretion by the anterior pituitary gland, followed within minutes by greatly increased adreno- cortical secretion of cortisol.

Because ACTH stimulates cortisol production in the adrenal gland, this results in hypercortisolism. In patients with hypercortisolism, this is the most common form. It occurs in about 80-85% of the patients [4, 6, 7]. In ACTH-independent hypercortisolism, elevated cortisol secretion is a …

In Synacthen test, synthetic ACTH is injected and we will monitor the levels of cortisol. Normally, the levels of cortisol should be high after the injection of the synthetic ACTH, which indicates normal adrenal cortex. However, if cortisol levels value is not raised, this will give us an indication that the patient has Addison’s disease.
ACTH
In patients who have ACTH-secreting pituitary tumors, the elevated levels of ACTH “drive” the adrenal cortex to make excessive amounts of cortisol, a glucocorticoid, as well as aldosterone, a mineralocorticoid, and several weak androgens; high levels of these hormones (over time) cause many serious and significant medial problems and ...
