The sensitivities and specificities of three enzyme-linked immunosorbent
assays (ELISAs) for Borrelia burgdorferi antibodies were compared for 41
patients presenting with symptoms compatible with late Lyme borreliosis
(LB) and 37 healthy controls. All subjects were living in southwestern
Finland, where LB is endemic. Only patients with culture- or PCR-proven
disease were enrolled in the study. The antigens of the ELISAs consisted of
sonicated spirochetes, 41-kDa flagellin, and recombinant P39 protein of B.
burgdorferi. Fifteen patients had strongly or moderately positive results
in the serological assay(s), 19 patients had only weakly positive or
borderline antibody levels, and the remaining 7 patients were seronegative
by ELISA. The sensitivities of the ELISAs were 78.0% with sonicate antigen,
41.5% with 41-kDa flagellin, and 14.6% with P39 protein. The specificities
of the tests were 89.2, 86.5, and 94.6%, respectively. The sonicate antigen
ELISA seems to be an effective screening method. These results show that
antibodies to B. burgdorferi may be present in low levels or even absent in
patients with culture- or PCR-proven late LB. Therefore, in addition to
serological testing, the use of PCR and cultivation is recommended in the
diagnosis of LB.
