Lyme borreliosis and multiple sclerosis: any connection? A seroepidemic study

A total of 769 adult neurological patients hospitalised in clinics and hospitals situated in the Lublin region (eastern Poland) were examined during the years 1997-2000 with ELISA test for the presence of anti-Borrelia burgdorferi sensu lato antibodies. A statististically significant (p=0.0422) relationship was found between the clinically confirmed diagnosis of multiple sclerosis and the positive serologic reaction with Borrelia antigen. Ten out 26 patients with multiple sclerosis (38.5%) showed positive serologic reaction to Borrelia, whereas among the total number of examined neurological patients the frequency of positive findings was twice as low (19.4%). The result suggests that multiple sclerosis may be often associated with Borrelia infection
