[Diagnosis and therapy of Lyme arthritis]

Several distinct patterns of rheumatic manifestations can be seen throughout the course of Lyme borreliosis: intermittent and migratory musculoskeletal pain without objective findings, intermittent arthritis, chronic erosive arthritis, and joint deformities under affected skin in acrodermatitis chronica atrophicans. Commonly, Lyme arthritis is a late disease manifestation. A clinical history of extra-articular disease manifestations is the most reliable key to Lyme arthritis. However, arthritis often occurs without antecedent early-disease manifestations. The diagnostic significance of serological findings suggesting Lyme arthritis must be considered carefully with regard to the typical clinical features of Lyme arthritis and its potential differential diagnoses. Otherwise, Lyme arthritis will be frequently over-diagnosed. Lyme arthritis can be cured with antibiotics. However, treatment failures occur with any of the hitherto recommended regimens.
