Cross-reaction between Yersinia outer membrane proteins and anti-Borrelia antibodies in sera of patients with Lyme disease.
Diagnosis of Yersinia infections accompanied by reactive arthritis could be complicated by cross-reaction with other arthritogenic bacteria. The possible cross-reaction between Yersinia antigens and anti-Borrelia antibodies in blood sera of patients with Lyme disease was studied. The occurrence of specific IgA, IgG and IgM antibodies was analyzed in serum samples from 30 patients with Yersinia-triggered reactive arthritis, 30 patients with Lyme disease and five samples from healthy blood donors. For anti-Borrelia IgG antibodies, cross-reaction was detected with YopH, YopB, V-ag, YopD, YopN, YopP and YopE, and for IgA with YopD. For IgM, no cross-reaction was detected. Owing to cross-reactivity with Borrelia, the diagnosis of Yersinia-triggered reactive arthritis should be based on a combination of serological and clinical findings.
