Abstract
Sera of 34 patients with progressive systemic sclerosis and of 11 patients with polymyositis/dermatomyositis (PM/DM) were analyzed by the immunoblotting technique for the presence of marker antibodies. The presence of anti-centromere, anti-Topoisomerase-I (anti-Topo-I) and anti-Jo-1 antibodies was found to be highly specific for the CREST syndrome, diffuse scleroderma and PM/DM, respectively, but only of limited sensitivity (78, 44 and 45%, respectively). Anti-Topo-I positive diffuse scleroderma patients had a more severe disease (digital pitting scars and renal insufficiency) than anti-Topo-I negative diffuse scleroderma patients. Anti-Jo-1 was associated with interstitial lung disease. Longitudinal studies showed a constant antibody pattern. Our results confirm the clinical usefulness of these marker antibodies.Entities:
