[Chronic fatigue syndrome--a defined unity?].
Chronic fatigue syndrome (CFS) is characterized by a sudden onset of an influenza-like illness followed by marked chronic fatigue and abnormal exercise-induced exhaustion. The precise pathogenesis of this disorder is unknown, but viral infection triggering immune imbalance has been suggested. The literature on CFS is reviewed. We find no consistent support for chronic viral infection or immunological dysfunction. The data in the published studies are rather conflicting, and further research in order to identify parameters that differentiate CFS from other disorders is necessary.
