Autoantibody to mitotic spindle associated antigen (MSA) was examined in sera from patients with positive mycoplasma pneumoniae particle agglutination (PA) test along with various autoimmune diseases and healthy subjects by means of indirect immunofluorescence (IF) using HEp-2 cells as substrates. Anti-MSA antibody was identified in 9 patients sera including 7 out of 180 sera with positive mycoplasma pneumoniae PA test, one with systemic lupus erythematosus (SLE) and one with scleroderma (PSS) respectively. Five of 9 sera with positive anti-MSA antibody contained anti-nuclear antibody (ANA) including 4 with speckled staining ANA and one with homogeneous + nucleolar staining ANA. Two collagen diseases sera positive for anti-MSA antibody showed negative mycoplasma pneumoniae PA test. In addition, there was no correlation between the presence of anti-MSA antibody and the titers of mycoplasma pneumoniae PA test. Our results indicated that anti-MSA antibody was not limited to such connective tissue diseases as previously described by other workers. It would be speculated that mycoplasma pneumoniae infection might induce anti-MSA antibody production.
