[Late manifestations of Lyme borreliosis].

Month to years after an early local or an early disseminated infection some patients develop late manifestations of lyme borreliosis. Most frequently involved organs are the skin (acrodermatitis chronica atrophicans), joints (Lyme arthritis) and the nervous system. A history of exposure and the clinical picture may suggest Lyme borreliosis, however, confirmation by serological and other tests is needed. Antibiotic treatment during early stages normally prevents development of late manifestations. Late stages persist if not treated. By adequate antimicrobial therapy they are treatable and usually show a good prognosis. Recovery may be delayed, some patients suffer from residual difficulties. Currently there is no accepted case definition for a "post lyme syndrome". The term "chronic Lyme disease" suggests (a never proven) persistent infection by viable bacteria. Repeated and prolonged antibiotic treatments are not indicated.
