Altered negative feedback control of the hypothalamic-pituitary-adrenocortical (HPA) system is a frequent laboratory sign of major depression. It coincides with depressive episodes and partially reverses after recovery from psychopathology. Such an HPA disturbance in feedback control can be acquired as a result of stressful life experiences and be compounded by age or it can be genetically predetermined at all levels involved in fine-tuned neuroendocrine regulation. Major psychiatric disorders run in families and a high familial load for an affective illness therefore increases an individual's risk of becoming affected. We investigated whether the HPA feedback disturbance observed among patients with depression is present in otherwise healthy individuals who are at high risk for psychiatric disorders because they have a first-degree relative with an affective illness. Using rigid psychodiagnostic techniques, we screened 431 consecutively admitted patients with depression and identified 35 families with one or more high-risk probands (HRPs). The results of a combined dexamethasone/human corticotropin-releasing hormone (DEX-CRH) test showed that the group of dexamethasone-pretreated (1.5 mg; 23.00 h) HRPs released more cortisol after stimulation with human CRH (100 micrograms; 15.00 h the next day) than a control group (CPs), but less than a group of patients with an acute major depressive episode (DPs). The peak cortisol values were 146.1 +/- 147.7 nmol/l (mean +/- SD) (HRPs), 75.3 +/- 47.9 nmol/l (CPs) and 278.2 +/- 199.2 nmol/l (DPs), yielding significant (F = 9.66, p < 0.001) group differences, with values for HRPs vs. CPs and HRPs vs. DPs being significant at the 1% level (t test).(ABSTRACT TRUNCATED AT 250 WORDS)
