[The chronic fatigue syndrome. A multifactorial approach and the treatment possibilities].
The chronic fatigue syndrome is a poorly defined symptoms complex characterized primarily by chronic or recurrent debilitating fatigue and various combinations of other symptoms, including psychological symptoms, sore throat, lymph node pain, headache, myalgia, arthralgias. Psychological disturbances, ranging from mild depression or anxiety to severe behavioral abnormalities, are always present. Chronic fatigue syndrome is the name that more accurately describes this symptom complex of unknown cause. A viral aetiology has long been hypothesized: many viruses are potential candidates, including any of the 23 Coxsackie A or 6 Coxsackie B viruses, herpes viruses, particularly Epstein-Barr virus and varicella. These studies, though interesting, remain unconvincing because of methodological flaws such as a poor case definition and inadequate control groups. This syndrome may represent an infection by a yet unidentified virus. It is more likely due to an abnormal immune response toward different intracellular pathogens. There is no treatment to ameliorate the chronic fatigue syndrome. Epidemiological studies are essential with explicit operational case definition before progress can be made in the management of this distressing disorder.
