[Lyme borreliosis and Lyme neuroborreliosis - an update].

Lyme borreliosis is a tick-borne infectious disease caused by the spirochete bacterium Borrelia burgdorferi sensu lato. Lyme borreliosis is the most frequent zoonosis in Germany.Most cases show dermatological manifestations, like erythema migrans, followed by infections of the nervous system. Cerebrospinal fluid analysis should be performed if Lyme neuroborreliosis is suspected. Cell-based assays (like LTT or ELISPOT) should not be used when investigating Lyme disease.A recent randomized controlled trial showed a similar effect of doxycycline compared to betalactam-antibiotics regarding neurological symptoms in Lyme neuroborreliosis. This corroborates current German guideline recommendations.The prognosis of Lyme disease after antibiotic treatment is usually favorable. Frequency of fatigue, depression, impairments in quality of life and cognitive impairment are similar in patients after treatment of Lyme neuroborreliosis when compared to the general population.
