The discriminatory power of three clinical tests for adrenal activity are compared by measuring the variability of the results obtained in 40 normal control subjects, 35 patients with mild essential hypertension, and 13 patients with Cushing syndrome. The variance of the 24-h integrated plasma concentration of cortisol was significantly (P < 0.0001) smaller than the variance of the 24-h urinary excretion of 17-hydroxycorticosteroids and free cortisol. While the 24-h urinary excretion of 17-hydroxycorticosteroids and free cortisol of the patients with Cushing syndrome overlapped with the corresponding values of the normal and hypertensive subjects, their integrated cortisol concentration did not exhibit any overlap.

D007700 Kinetics The rate dynamics in chemical or physical systems.
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D003480 Cushing Syndrome A condition caused by prolonged exposure to excess levels of cortisol (HYDROCORTISONE) or other GLUCOCORTICOIDS from endogenous or exogenous sources. It is characterized by upper body OBESITY; OSTEOPOROSIS; HYPERTENSION; DIABETES MELLITUS; HIRSUTISM; AMENORRHEA; and excess body fluid. Endogenous Cushing syndrome or spontaneous hypercortisolism is divided into two groups, those due to an excess of ADRENOCORTICOTROPIN and those that are ACTH-independent.

D006854 Hydrocortisone The main glucocorticoid secreted by the ADRENAL CORTEX. Its synthetic counterpart is used, either as an injection or topically, in the treatment of inflammation, allergy, collagen diseases, asthma, adrenocortical deficiency, shock, and some neoplastic conditions.
