Hypoadrenocorticism in dogs, or, as it is known in people, Addison's disease, is an endocrine system disorder that occurs when the adrenal glands fail to produce enough hormones for normal function. The adrenal glands secrete glucocorticoids such as cortisol [ 1 ] and mineralocorticoids such as aldosterone ; [ 2 ] when proper amounts of these ...
The ACTH test (also called the cosyntropin, tetracosactide, or Synacthen test) is a medical test usually requested and interpreted by endocrinologists to assess the functioning of the adrenal glands' stress response by measuring the adrenal response to adrenocorticotropic hormone (ACTH; corticotropin) or another corticotropic agent such as tetracosactide (cosyntropin, tetracosactrin; Synacthen ...
Individuals with Addison's disease have more than a doubled mortality rate. [37] Furthermore, individuals with Addison's disease and diabetes mellitus have an almost four-fold increase in mortality compared to individuals with only diabetes. [38] The risk ratio for cause mortality in males and females is 2.19 and 2.86, respectively. [37]
The most common cause of primary adrenal insufficiency (Addison's disease) overall is autoimmune adrenalitis. [2] The prevalence of Addison's disease ranges from 5 to 221 per million in different countries. [30] In children, congenital adrenal hyperplasia (CAH) is the most common cause of adrenal insufficiency, with an incidence 1 in 14,200 ...
In this form of meningococcal disease, meningitis generally does not occur. Low levels of blood glucose and sodium, high levels of potassium in the blood, and the ACTH stimulation test demonstrate the acute adrenal failure. Leukocytosis need not be extreme and in fact leukopenia may be seen and it is a very poor prognostic sign.

A low-dose ACTH stimulation test has been suggested as a sensitive test for secondary adrenal insufficiency diagnosis. [10] When compared to insulin tolerance testing [11] and the high-dose ACTH test, this test allows for a more accurate identification of patients with secondary adrenal insufficiency. [12]
Conversely, chronically elevated ACTH levels occur in primary adrenal insufficiency (e.g. Addison's disease) when adrenal gland production of cortisol is chronically deficient. In Cushing's disease, a pituitary tumor leads to excessive production of ACTH, which stimulates the adrenal cortex to produce high levels of cortisol
