title: Significance and specificity of anti-SSA/Ro antibody in patients with bullous disorders.
abstract: Sera from 45 patients with pemphigus and from 25 patients with bullous pemphigoid were screened for the presence of anti-SSA/Ro autoantibody by double immunodiffusion and SSA/Ro enzyme-linked immunosorbent assay and immunoblot analysis. Totally 6 of them were found to have IgG4 subclass anti-SSA/Ro antibody by SSA/Ro enzyme-linked immunosorbent assay, and this was further confirmed by immunoblot analysis. None of these 6 patients have any evidence of symptoms or signs for connective tissue disease.
