Abstract:
The chronic fatigue syndrome (CFS) is characterized by a feeling of tiredness persisting for over 6 months, associated with a number of other symptoms including headaches, myalgia and arthralgia, memory and concentration impairment. Its cause is unknown, there are neither objective diagnostic methods, nor causal treatment of the condition. In view of hypotheses suggesting a relationship between CFS and infections, 86 patients with a history of borreliosis or tick-borne encephalitis were examined. In 50% of these cases CFS could be identified. This clinical pattern was found in as many as 71% of the borreliosis patients, while only 24% of those with history of tick-borne encephalitis were diagnosed with CFS. Moreover, in the patients with a history of borreliosis after symptomatic treatment recommended for CFS, an amelioration was noted in as many as 61% of the cases. The findings suggest that the chronic fatigue syndrome is frequent among patients with a history of borreliosis.
