Abstract
The antibody responses to Epstein-Barr nuclear antigen (EBNA) polypeptides were analyzed by immunoblotting in 93 patients with autoimmune connective tissue diseases (ACTD) in comparison with 50 clinically healthy control subjects. Antibody frequencies to EBNA-2, -4 and -6 were signficantly higher in patients than in controls. Among the patients with ACTD, those with systemic lupus erythematosus (SLE) showed a significant increase in the frequency of anti-EBNA-3 antibodies. These results confirm the particularity of the antibody responses against Epstein-Barr virus (EBV) polypeptides in patients with ACTD; they could either reflect basic immune disturbances or suggest a participation of EBV in the pathogenesis of the disease.
