Long-term findings in patients with facial palsy and antibodies against Borrelia burgdorferi.

Abstract

Little is known about the long-term effects of Borrelia burgdorferi (Bb) infection in untreated patients with peripheral facial palsy. We investigated 12 patients with elevated serum Bb antibody levels, with a median follow-up time of 11 years, during which 3 of the 12 still exhibited intrathecal antibody production of antibodies against Bb flagellar antigen, and 2 of the 3 had normal serum Bb antibodies. Four of the 12 had elevated serum antibody titres at the late follow-up examination. Arthralgia, reported by 7 patients, was the single most common complaint. Four patients showed extensive oculomotor disturbances, which were not correlated to antibody titres or intrathecal antibody synthesis. In 1 of the patients with intrathecal Bb antibody production, most symptoms were eradicated by antibiotic treatment 6 years after the initial infection. We conclude that even several years after a Bb infection, intrathecal Bb antibody production can still occur in serum Bb IgG antibody negative patients with a history of facial palsy.
