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]
In the insufficiency of 21-hydroxylase to participate in the biosynthesis of cortisol, the 21-hydroxylation in the zona fasciculata of the adrenal cortex is impaired, so 17OHP and progesterone will not be properly converted into 11-deoxycortisol and 11-deoxycorticosterone, respectively − the precursors for cortisol and aldosterone.
Adrenal crisis is a serious, life-threatening complication of adrenal insufficiency. Hypotension , or hypovolemic shock , is the main symptom of adrenal crisis, other indications and symptoms include weakness , anorexia , nausea , vomiting, fever, fatigue , abnormal electrolytes , confusion , and coma.

An "adrenal crisis" or "Addisonian crisis" is a constellation of symptoms that indicates severe adrenal insufficiency. This may be the result of either previously undiagnosed Addison's disease, a disease process suddenly affecting adrenal function (such as adrenal hemorrhage ), or an intercurrent problem (e.g., infection, trauma) in someone ...
Adrenal hemorrhage characteristic of the Waterhouse–Friderichsen syndrome has been identified in several autopsies of patients who died of sepsis secondary to capnocytophaga canimorsus infection. [8] Viruses may also be implicated in adrenal problems: Cytomegalovirus can cause adrenal insufficiency, [9] especially in the immunocompromised.
When a person with adrenal insufficiency is known to be exhibiting symptoms of an adrenal crisis, treatment begins before diagnostic testing. [14] When adrenal insufficiency is suspected a blood sample can be collected to test serum cortisol and ACTH levels, while treatment begins during the wait for results. Once an acutely ill person has ...
Pale skin may contribute to patients' diminished appearance and aid in differentiating between primary and secondary adrenal insufficiency. Secondary adrenal insufficiency is not associated with a lack of aldosterone, so symptoms and signs of mineralocorticoid deficiency, such as salt craving, postural hypotension, and electrolyte abnormalities ...
Adrenal insufficiency Before 7.5 years Up to 50% in childhood, varies with age Asymptomatic No clinical presentation, further studies can reveal subclinical adrenal insufficiency or mild AMN phenotype Most common phenotype in boys under four years of age Proportion of asymptomatic patients decreases with age
