Congenital adrenal hyperplasia (CAH) refers to any of several autosomal recessive diseases resulting from defects in steps of the synthesis of cortisol from cholesterol by the adrenal glands. All of the forms of CAH involve excessive or defective production of sex steroids and can prevent or impair development of primary or secondary sex characteristics in affected infants, children, and adults. Many also involve excessive or defective production of mineralocorticoids, which can cause WebEndogenous production of excess glucocorticoids caused by spontaneous hyperadrenocorticism also results in steroid hepatopathy. Hepatic lesions are identical to those seen with exogenous administration of glucocorticoids. • Dogs with atypical hyperadrenocorticism can also develop lesions of steroid hepatopathy.
WebThe 11-deoxycortisol levels normally increase to 100 times the control value following metyrapone administration. Reduced response occurs in patients with hypoadrenalism or with hypopituitarism and in some patients with diseases of the hypothalamus. Patients with myxedema, some pregnant patients, and those on oral contraceptives respond poorly. WebThe substrate for P450c11 is 11-deoxycortisol.

WebResults: Our results showed that adrenal insufficiency of any cause was adequately diagnosed using the response of 11-deoxycortisol, dehydroepiandrosterone, or these analytes combined in a two-steroid profile. A three-steroid profile yielded a test with 100% accuracy for discriminating primary adrenal insufficiency from normal status.
