OBJECTIVE Subtle dysregulations of the hypothalamus-pituitary-adrenal axis in chronic fatigue syndrome have been described. The aim of this study was to examine the negative feedback regulations of the hypothalamus-pituitary-adrenal axis in chronic fatigue syndrome. METHODS In 21 patients with chronic fatigue syndrome and 21 healthy control subjects,(More)
OBJECTIVE It has been suggested that a hypofunctional hypothalamic-pituitary-adrenal (HPA) axis in chronic fatigue syndrome could result in an exaggerated release of pro-inflammatory cytokines during stress. As pro-inflammatory cytokines are involved in the induction of sickness behavior and thus constitute a potential physiological correlate of(More)
OBJECTIVES Subtle alterations of the hypothalamic-pituitary-adrenal (HPA) axis in chronic fatigue syndrome (CFS) have been proposed as a shared pathway linking numerous etiological and perpetuating processes with symptoms and observed physiological abnormalities. Because the HPA axis is involved in the adaptive responses to stress and CFS patients(More)
OBJECTIVE Subtle dysregulations of the hypothalamic-pituitary-adrenal (HPA) axis have been proposed as an underlying pathophysiological mechanism in chronic fatigue syndrome (CFS). This study attempted to assess the relationship between patient characteristics and HPA axis functioning using a neuroendocrine challenge test. METHOD A test battery designed(More)
OBJECTIVE Alterations of the immune-neuroendocrine interplay have been described in chronic fatigue syndrome (CFS). Employing a recently developed method, the study set out to investigate whether patients with CFS have an altered sensitivity to glucocorticoids (GCs) when under stress. METHODS A total of 21 CFS patients and 20 healthy age- and(More)
A reduced secretion of cortisol has been proposed as a possible explanation of the symptoms in chronic fatigue syndrome. However, the evidence of hypocortisolism in chronic fatigue syndrome is conflicting. In order to simultaneously assess possible alterations in adrenocortical sensitivity and secretory adrenal reserve, the authors administered both(More)
