This study investigates the seroreactivity to Borrelia burgdorferi antigens
of patients suffering from rheumatoid arthritis (RA) for < 5 yr.
Subjects were matched with controls for age, sex and area of residence in
order to minimize the risk of differential exposure to B. burgdorferi. A
total of 57 pairs were tested by immunofluorescence assay (IFA) and Western
blotting. Only two RA patients showed positive IFA results, and another was
positive by Western blot analysis. No significant difference in Lyme
seropositivity was detected between cases and controls using either
serological test. Furthermore, no significant difference in antibody
response was observed to specific or non-specific proteins (e.g. Osp C, 93
kDa protein, flagellin, heat shock proteins). These results do not support
the previous suggestions that B. burgdorferi may be involved in the
aetiology of RA, or that RA favours the production of antibodies that
cross-react with B. burgdorferi proteins.
