Abstract

Earlier reports have suggested that dexamethasone significantly increases levels of plasma homovanillic acid (HVA) in normal subjects, but that this effect may be altered in some depressed patients. To investigate the specificity of such alterations, we administered dexamethasone (1 mg p.o. at 11 p.m.) to 33 normal subjects, 27 depressed patients (8 with psychotic features), and 16 schizophrenic patients. Plasma for assay of cortisol and HVA was obtained at 4 p.m. before and on the day following dexamethasone administration. Dexamethasone induced significant increases in plasma HVA in the normal subjects and in the schizophrenic patients, but not in the depressed patients. Indeed, psychotically depressed patients tended to show a dexamethasone-associated decrease in plasma levels of HVA. In contrast to cortisol "suppression" or "nonsuppression", dexamethasone-induced changes in plasma levels of HVA (i.e., increases or decreases) sensitively and specifically discriminated between patients with affective and nonaffective psychoses.
