The 83-kDa antigen of Borrelia burgdorferi was expressed as a recombinant
protein in Escherichia coli and purified for use in an enzyme-linked
immunosorbent assay (p83-ELISA). Antibodies to the 83-kDa antigen of both
the immunoglobulin G (IgG) and IgM isotypes could be detected in all stages
of Lyme disease. Sensitivity varied, depending on the clinical stage of
illness. In early stages, as defined for 118 patients with erythema
migrans, it was found to be 20% (24 of 118 patients: 7 with IgM, 16 with
IgG, and 1 with IgM and IgG). Of the patients with late-stage Lyme
arthritis and acrodermatitis chronica atrophicans, 94% (16 of 17:2 with IgM
and IgG and 14 with IgG) and 86% (36 of 42:2 with IgG and IgM and 34 with
IgG) revealed positive results in the p83-ELISA, respectively. p83 displays
sequence heterogeneity according to the genomospecies, but when the
reactions of serum specimens from acrodermatitis chronica atrophicans
patients and arthritis patients with p83 derived from representative
strains of B. burgdorferi sensu stricto and Borrelia afzelii in ELISAs were
compared, no differences in specificity and sensitivity were seen. When 82
serum specimens from healthy controls were tested, none had IgG and only 3
(4%) had IgM antibodies, indicating a high specificity. Positive reactions
with antibodies against Treponema pallidum (1 of 37 patients; IgG) and
Epstein-Barr virus (1 of 44 patients; IgM) and with autoantibodies of
various specificities (1 of 53 patients; IgG) were seen with < 3% of the
serum samples te11111111111111111111 high speficicity for B. burgdorferi.2+
13% for IgM antibodies, the IgM p83- ELISA provided little diagnostic
information for Lyme disease, whereas the IgG p83-ELISA appears to be a
suita ;e test for serodiagnosis of advanced-stage Lyme disease.
