Cushing’s disease history and symptoms
From Wikidoc - Reading time: 3 min
Overview
[edit | edit source]Cushing's disease (also known as Cushing disease, tertiary or secondary hypercortisolism, tertiary or secondary hypercorticism, Itsenko-Cushing disease)[1][2] is a cause of Cushing's syndrome characterised by increased secretion of adrenocorticotropic hormone (ACTH) from the anterior pituitary (secondary hypercortisolism). This is most often as a result of a pituitary adenoma (specifically pituitary basophilism) or due to excess production of hypothalamus CRH (Corticotropin releasing hormone) (tertiary hypercortisolism/hypercorticism) that stimulates the synthesis of cortisol by the adrenal glands. Pituitary adenomas are responsible for 80% of endogenous Cushing's syndrome,[3] when excluding Cushing's syndrome from exogenously administered corticosteroids.
This should not be confused with ectopic Cushing syndrome or exogenous steroid use.[4]
History and Symptoms
[edit | edit source]The symptoms of Cushing's disease are similar to those seen in other causes of Cushing's syndrome.[5] Patients with Cushing's disease usually present with one or more signs and symptoms secondary to the presence of excess cortisol or ACTH.[6] Although uncommon, some patients with Cushing's disease have large pituitary tumors (macroadenomas). In addition to the severe hormonal effects related to increase blood cortisol levels, the large tumor can compress adjacent structures. [citation needed] These tumors can compress the nerves that carry information from the eyes, causing a decrease in peripheral vision.[citation needed] Glaucoma and cataracts also may occur in Cushing's syndrome. In children, the two main symptoms are obesity and decreased linear growth.[7]
The clinical diagnosis must be based on the presence of one or more of the symptoms listed below, because the syndrome itself has no true pathognomonic signs or symptoms.[citation needed] The most common symptoms seen in male patients are purple striae, muscle atrophy, osteoporosis, and kidney stones.[7]
