WebAbstract. Objective: The high-dose dexamethasone (dex) suppression test of cortisol secretion (8 x 2 mg dex over two days or 8 mg overnight) is a mainstay in the differential diagnosis of Cushing's syndrome (CS). In some patients with pituitary Cushing's disease (CD), however, plasma cortisol is not suppressed to < 50% of control by 8 mg of dex. WebAfter a standard overnight 1-mg dexamethasone test, which served as a reference, three other tests were randomly performed at 1-wk intervals by administering 0.0035, 0.0070, and 0.015 mg oral dexamethasone per kilogram of body weight overnight. Blood samples were obtained for cortisol, ACTH, and dexamethasone. WebObjective: To determine the effects of dexamethasone or synthetic ACTH administration on endogenous ACTH concentrations in healthy dogs. Animals: 10 healthy neutered dogs. Procedures: Each dog received dexamethasone (0.01 mg/kg), synthetic ACTH (5 μg/kg), or saline (0.9% NaCl) solution (0.5 mL) IV at intervals of ≥ 30 days. inch timmendorfer strand
