Waterhouse–Friderichsen syndrome (WFS) is defined as adrenal gland failure due to hemorrhages in the adrenal glands, commonly caused by sepsis. Typically, the bacteria responsible for triggering the bleeding is Neisseria meningitidis. [1] The bacterial infection leads to massive bleeding into one or both adrenal glands. [2]
Adrenal insufficiency can also result when a patient has a brain mass in the pituitary gland (e.g. pituitary adenoma, craniopharyngioma) which can take up space and interfere with the secretion of pituitary hormones such as ACTH, therefore leading to decreased adrenal stimulation (secondary adrenal insufficiency). [2]
Rapid onset of symptoms indicates acute adrenal failure, which is a clinical emergency. [5] An adrenal crisis can be triggered by stress, such as from an injury, surgery, or infection. [1] Addison's disease arises when the adrenal gland does not produce sufficient amounts of the steroid hormones cortisol and (sometimes) aldosterone. [1]
Adrenal insufficiency is the clinical sign of insufficient glucocorticoid production or action, with or without concurrent insufficiency in mineralocorticoids and adrenal androgens. [21] Adrenocorticotropic hormone deficiency or exogenous glucocorticoid or opioid medication suppression of adrenocorticotropic hormone can cause adrenal ...
Other stimulation tests for adrenal insufficiency which are used in non-critical patients, such as the test using metyrapone or a test which employs insulin to induce hypoglycemia, are not preferred for CIRCI. [6] Both a metyrapone-induced decrease in cortisol and hypoglycemia are potentially harmful to intensive care patients.
The syndrome was first identified by Jeremy Allgrove and colleagues in 1978; since then just over 100 cases have been reported. [3] The syndrome is called Triple-A due to the manifestation of the illness which includes achalasia (a dysfunction of the esophagus), addisonianism (adrenal insufficiency of primary type), and alacrima (insufficiency ...
Nelson's syndrome is a disorder that occurs in about one in four patients who have had both adrenal glands removed to treat Cushing's disease. [1] In patients with pre-existing adrenocorticotropic hormone ()-secreting pituitary adenomas, loss of adrenal feedback following bilateral adrenalectomy can trigger the rapid growth of the tumor, leading to visual symptoms (e.g. bitemporal hemianopsia ...
Clinical manifestations of adrenocorticotropic hormone deficiency are similar to those of primary adrenal insufficiency, except for cutaneous hyperpigmentation and electrolyte disturbances. [ 2 ] Adrenocorticotropic hormone deficiency is characterized by nonspecific symptoms such as fatigue , anorexia , unintentional weight loss , and ...
