title: Evening urine cortisol excretion and DST results in depression and anorexia nervosa.
abstract: Cortisol determination in a single one-hour urine sample collected between 2200 h and 2300 h has been shown to identify accurately patients with Cushing's disease. To examine the usefulness of this procedure for identifying psychiatric patients with a pituitary-adrenal disturbance, we studied 17 drug-free depressed patients, 6 euthymic anorectic patients and 10 healthy volunteers. We found that there was good agreement between DST results and evening urine cortisol excretion in this sample (when cortisol levels were expressed as ng of cortisol per mg of creatinine), and that adopting as a criterion a urine cortisol value two standard deviations above the mean cortisol value of the controls predicts 74% of the dexamethasone suppression test (DST) results. We would like to suggest that this measure deserves further study as a potentially useful and simple alternative to the DST for identifying psychiatric patients with a pituitary-adrenal disturbance.
