• Antinuclear antibody (ANA) test results were correlated with the clinical status of 56 patients with systemic scleroderma. Three groups were identified. (1) The speckled pattern represented a benign clinical subset. Acrosclerosis, Raynaud's phenomenon, calcinosis, and esophageal dysmotility characterized this group. None of these patients had pulmonary, renal, or cardiac disease. (2) Two patterns and ANA-negative test results were associated with a different incidence of certain clinical characteristics. The thready pattern was associated with pulmonary involvement. Diffuse skin involvement and Raynaud's phenomenon were found with the nucleolar pattern. Patients with ANA-negative test results had the most severe disease, including renal failure. (3) Two patterns were not associated with different clinical characteristics. These were the small speckle-like thready pattern and the homogeneous pattern. This study supports the theory that ANA patterns may be used as imunologic markers for different clinical characteristics of patients with scleroderma as they have already been used in lupus erythematosus.
