Hypersensitivity to these agents depressed sodium or potassium serum levels marked kidney and liver disease or dysfunction suprarenal gland failure hyperchloremic acidosis adrenocortical insufficiency severe pulmonary obstruction with inability to increase alveolar ventilation since acidosis may be increased (dichlorphenamide) cirrhosis (acetazolamide, methazolamide) long-term use in chronic noncongestive angle-closure glaucoma. 

Chronic adrenocortical insufficiency is characterized by weakness, fatigue, weight loss, hypotension, hyperpigmentation, and inability to maintain the blood glucose level during fasting. In such individuals, minor noxious, traumatic, or infectious stimuli may produce acute adrenal insufficiency with circulatory shock and even death.

Drugs with mineralocorticoidlike activity (aldosterone agonists) are frequently administered as replacement therapy whenever the natural production of mineralo-corticoids is impaired. Mineralocorticoid replacement is usually required in patients with chronic adrenocortical insufficiency (Addison disease), following adrenalectomy, and in other forms of adrenal cortex hypofunction. These conditions usually require both mineralocorticoid and glucocorticoid replacement. 

Type E (Ending of use) reactions, where discontinuation of chronic therapy is too abrupt, e.g. of adrenal steroid causing rebound adrenocortical insufficiency, of opioid causing the withdrawal syndrome. 

Suppression ofhypothalamic/pituitary/adrenocortical feedback system (with delayed recovery) occurs with chronic use, so that abrupt withdrawal leaves the patient in a state of adrenocortical insufficiency.

Fludrocortisone is the compound that is most often used at present for long-term mineraiocorticoid treatment. The dose of fludrocortisone needed in chronic adrenocortical insufficiency varies very widely, from 0.05... 

The immediate management of patients with acute adrenal insufficiency includes intravenous therapy with isotonic sodium chloride solution supplemented with 5% glucose and corticosteroids and appropriate therapy for precipitating causes such as infection, trauma, or hemorrhage. Because cardiovascular function often is reduced in the setting of adrenocortical insufficiency, the patient should be monitored for evidence of volume overload such as pulmonary edema. After an initial intravenous bolus of 100 mg, hydrocortisone (cortisol) should be given by continuous infusion at a rate of 50-100 mg every 8 hours. At this dose, which approximates the maximum daily rate of cortisol secretion in response to stress, hydrocortisone overwhelms the 11/1HSD2 barrier in mineralo-corticoid-responsive tissues and has sufficient mineralocorticoid activity to meet all requirements. As the patient stabilizes, the hydrocortisone dose may be decreased to 25 mg every 6-8 hours. Thereafter, patients are treated in the same fashion as those with chronic adrenal insufficiency see below). 

Of 62 initially autoantibody-negative patients treated with interferon alfa for chronic hepatitis C for a mean of 8 months, three developed antibodies to 21b-hydroxylase, a sensitive assay of adrenocortical autoimmunity (528). However, there were no cases of Addison s disease or subclinical adrenal insufficiency. This study suggested that the adrenal cortex is another potential target organ of autoimmune effects of interferon alfa, along with thyroid and pancreatic islet cells.
