|Abstract: ||We determined baseline 0800h plasma cortisol concentrations, 24-hr urinary free cortisol (UFC) excretion, the post-dexamethasone cortisol values at 0800h and 1600h, and the 0800h dexamethasone concentrations in 60 depressed patients categorized according to the DSM-III. Up to 59% of the variability in the 0800h post-dexamethasone cortisol values could be explained by the multiple regression on UFC, 0800h basal plasma cortisol, age (all positively related), and dexamethasone concentrations (negatively related). The 1600h post-dexamethasone cortisol data were best explained (i.e., 55% of the variance) by the multiple regression on basal plasma cortisol, UFC (positive) and dexamethasone (negative). After controlling for UFC, baseline plasma cortisol, and age no significant effects of the depressive state (diagnostic classification or severity of illness) on the post-dexamethasone cortisol values could be detected. It can be deduced that cortisol non-suppression during depression is related strongly to baseline cortisol hypersecretion and increasing age. These factors are additive and contribute independently towards cortisol escape from suppression by dexamethasone.|
