Abstract

Clinical significance of specific antinuclear antibodies (ANA) in Japanese patients with systemic sclerosis was studied. The patients with systemic sclerosis were classified into four groups according to ANA: (1) anticentromere antibody-positive; (2) anti-Scl-70 antibody-positive; (3) anti-nRNP antibody-positive, and (4) others. The mean score (the number of positive signs in six selected specific signs) of the patients with anti-Scl-70 antibody was significantly higher than those of the other three groups. More frequent contracture of phalanges in the patients with anti-Scl-70 antibody, less diffuse pigmentation in the patients with anti-nRNP antibody, and less pulmonary fibrosis in the patients with anticentromere antibody were revealed. As shown above, the detection of specific ANA in systemic sclerosis is clinically important.
