BACKGROUND The role of stress in the onset of chronic fatigue syndrome is unclear. Our objectives in this study were first, to determine the relation between the onset of chronic fatigue syndrome and stressful life events and difficulties. Secondly, we examined the role of a particular type of problem, dilemmas, in the onset of chronic fatigue syndrome. METHOD We used a case-control design wi...

OBJECTIVE To delineate the risk factors, symptom patterns, and longitudinal course of prolonged illnesses after a variety of acute infections. DESIGN Prospective cohort study following patients from the time of acute infection with Epstein-Barr virus (glandular fever), Coxiella burnetii (Q fever), or Ross River virus (epidemic polyarthritis). SETTING The region surrounding the township of D...

PURPOSE Chronic fatigue syndrome has been associated with decreased function of the hypothalamic-pituitary-adrenal axis. Although neurally mediated hypotension occurs more frequently in patients with chronic fatigue syndrome than in controls, attempts to alleviate symptoms by administration of hydrocortisone or fludrocortisone have not been successful. The purpose of this study was to investiga...

OBJECTIVES To examine cognitive function in chronic fatigue syndrome. METHODS Twenty patients with chronic fatigue syndrome recruited from primary care and 20 matched normal controls were given CANTAB computerised tests of visuospatial memory, attention, and executive function, and verbal tests of letter and category fluency and word association learning. RESULTS Patients with chronic fatig...

The syndrome of chronic fatigue, feverishness, diffuse pains, and other constitutional complaints, often precipitated by an acute infectious illness and aggravated by physical and emotional stressors, has a lengthy history in the medical literature. The Centers for Disease Control (CDC) recently formulated a case definition, renaming the illness "chronic fatigue syndrome." Nevertheless, there r...

In China, moxibustion is reported to be useful and has few side effects for chronic fatigue syndrome, but its mechanisms are largely unknown. More recently, the focus has been on the wealth of information supporting stress as a factor in chronic fatigue syndrome, and largely concerns dysregulation in the stress-related hypothalamic-pituitary-adrenal axis. In the present study, we aimed to deter...

BACKGROUND Mortality associated with chronic fatigue syndrome is uncertain. We investigated mortality in individuals diagnosed with chronic fatigue syndrome in secondary and tertiary care using data from the South London and Maudsley NHS Foundation Trust Biomedical Research Centre (SLaM BRC) Clinical Record Interactive Search (CRIS) register. METHODS We calculated standardised mortality ratio...

OBJECTIVE The aims of this study were to examine: (i) baseline pressure pain thresholds in patients with chronic fatigue syndrome and those with chronic low back pain compared with healthy subjects; (ii) the change in mean pain threshold in response to exercise; and (iii) associations with exercise-induced increase in nitric oxide. PARTICIPANTS Twenty-six patients with chronic fatigue syndrom...

A minimal intervention, based on cognitive-behavioural therapy for chronic fatigue syndrome and consisting of self-instructions combined with email contact, was tested in a randomised controlled trial (ISRCTN27293439). A total of 171 patients participated in the trial: 85 were allocated to the intervention condition and 86 to the waiting-list condition. All patients met the Centers for Disease ...
