For most of these antibodies, however, the role in pathogenesis is not established. Primary SS-ILD group, D. Its aetiology may be secondary to immunologic mechanisms, vascular endothelial cell injury and activation of fibroblasts. They also have pulmonary interstitial fibrosis and reduced survival. The anti-RNA Polymerase III antibody is the third major scleroderma antibody and is about as common as Scl-70 or centromere antibodies. The incidence of cardiac involvement was similar between the dcSSc groups, and scleroderma renal crisis was more frequent in the non-ACA diffuse group.

In this condition, the immune system mistakenly attacks and damages healthy body tissue. As mentioned above, the anti-RNA polymerase III antibody is associated with one of the diffuse variants of scleroderma and has a different typical clinical symptom profile than diffuse patients with the anti-Scl70 antibody (see Table 2). Some of the antibodies may be common in people with scleroderma. In SLE, three autoantibody tests—anti-Sm, dsDNA, and phospholipid—included in the classification criteria of SLE are commercially available in addition to standard immunofluorescent ANA.
