Four children with monarthritis of the knee had no further manifestations of
Lyme borreliosis, but a positive antibody titer against Borrelia burgdorferi as measured by Elisa. About 3 years after antibiotic therapy none of the children had arthritis, but one suffered from fibromyalgia and another child had still a vigorous reactivity against Borrelia burgdorferi antigens by Elisa and immunoblot. In this study 4 out of 20 children with recently recognized arthritis had
Lyme arthritis which makes it a rather frequent
disease. The clinical presentation could not distinguish these 4 children from 4 other children with monarthritis of the knee of unknown origin. In the absence of better diagnostic criteria, the association of monarthritis, not otherwise explained, with a positive
Lyme serology seems to be sufficient evidence to establish a diagnosis of
Lyme arthritis. After confirmation of the diagnosis children should be treated without delay.
