Adrenal insufficiency steroids

Endocrinologists are specialists in hormonal diseases, including adrenal and pituitary conditions that cause secondary adrenal insufficiency. An endocrinologist will have more training and experience in properly diagnosing and treating secondary adrenal insufficiency than most physicians. Most cases of permanent secondary adrenal insufficiency should be managed by an endocrinologist.  In cases of steroid withdrawal for the treatment of medical conditions, endocrinologists often work with the primary physician or specialist in that disease to assess the recovery of pituitary-adrenal reserve and provide guidance about whether long term glucocorticoid therapy is needed.

The electrolyte disturbances in primary adrenal insufficiency are due to diminished secretion of cortisol and aldosterone (see "Causes of primary adrenal insufficiency (Addison's disease)" ). A major function of aldosterone is to increase urinary potassium secretion. As a result, hypoaldosteronism can be associated with hyperkalemia and mild metabolic acidosis [ 1,2 ]. Sodium wasting is a variable feature of this disorder. It is not prominent in adults with isolated hypoaldosteronism, probably because aldosterone secretion is only modestly reduced. (See "Etiology, diagnosis, and treatment of hypoaldosteronism (type 4 RTA)" .)

The clinical presentation of adrenal insufficiency is variable, depending on whether the onset is acute, leading to adrenal crisis, or chronic, with symptoms that are more insidious and vague. Therefore, the diagnosis of adrenal insufficiency depends upon a critical level of clinical suspicion. Adrenal crisis should be considered in any patient who presents with peripheral vascular collapse (vasodilatory shock), whether or not the patient is known to have adrenal insufficiency. Likewise, isolated corticotropin (ACTH) deficiency, although rare, should be considered in any patient who has unexplained severe hypoglycemia or hyponatremia. (See "Clinical manifestations of adrenal insufficiency in adults" .)

A discussion on stress should include recognition of Dr. Hans Selye. His classic work on stress ( The Stress of Life , McGraw- Hill Book Co., .) and his many other publications report “that our various internal organs, especially the endocrine glands and the nervous system, help to adjust us to the constant changes which occur in and around us. He calls this adjustment the General Adaptation Syndrome. Selye concluded that the adrenals were the body’s prime reactors to stress. He stated that the adrenals “…are the only organs that do not shrink under stress; they thrive and enlarge. If you remove them, and subject an animal to stress it can’t live. But if you remove them, and then inject extract of cattle adrenals (cortex), stress resistance will vary in direct proportion to the amount of the injection, and even be put back to normal.” Likewise a person’s stress resistance will vary with the competence of his adrenals, but continually stressing the adrenals finally depletes them.

During minor illness (., flu or fever >38° C [° F]) the hydrocortisone dose should be doubled for 2 or 3 days. The inability to ingest hydrocortisone tablets warrants parenteral administration. Most patients can be educated to self administer hydrocortisone, 100 mg IM, and reduce the risk of an emergency room visit. Hydrocortisone, 75 mg/day, provides adequate glucocorticoid coverage for outpatient surgery. Parenteral hydrocortisone, 150 to 200 mg/day (in three or four divided doses), is needed for major surgery, with a rapid taper to normal replacement during the recovery. Patients taking more than 100 mg hydrocortisone/day do not need any additional mineralocorticoid replacement. All patients should wear some form of identification indicating their adrenal insufficiency status.

In the ., the most common cause (about 75%) of primary adrenal insufficiency in adults is an autoimmune process. It may occur with other autoimmune conditions that affect other glands, such as the thyroid. The rest of the time, Addison disease is due to other causes, such as tuberculosis , a common cause in areas of the world where tuberculosis is more prevalent , other chronic infections, especially fungal infections , bleeding into the adrenal glands ( hemorrhage ) and the spread of cancer into the adrenal glands. Rarely, it may be due to a genetic abnormality of the adrenal glands.
