ACTH

A 39-amino acid hormone produced by the anterior pituitary gland, which regulates adrenocortical activity, stimulating release of cortisol, mineralocorticoids, and adrenal androgens; pituitary ACTH is regulated by corticotropin-releasing hormone (CRH).
Daily pattern ACTH levels vary over the space of a 24-hour day, peaking at 6–8 am and evening 6–11 pm; ACTH suppression or stimulation testing may be required to confirm the diagnosis of changes in adrenal function.
ACTH increased in Addison’s disease, congenital adrenal hyperplasia, Cushing disease, pituitary-dependent Cushing syndrome, ectopic ACTH-producing tumours, Nelson syndrome.
ACTH decreased in Secondary adrenocortical insufficiency, adrenal carcinoma, adenoma.

ACTH

Adrenocorticotropic HORMONE. This hormone is produced by the pituitary gland, on instructions from the hypothalamus (the part of the brain immediately above the gland) when a stressful situation arises. ACTH is carried by the blood to the adrenal glands and prompts them to secrete the hormone cortisol into the bloodstream. ACTH is sometimes used as medication.
