Abstract
Fifty-one patients with lupus erythematosus were studied retrospectively. They were chosen on the basis of their antinuclear antibody (ANA) immunofluorescent pattern. Only those with the thready or the large speckle-like thready patterns were studied. Autoantibody profiles consisting of ANA, anti-single-stranded deoxyribonucleic acid (ssDNA) antibody, and anti-extractable nuclear antigen (ENA) antibody determinations were obtained. The patients with the thready ANA pattern and anti-ENA (Sm) antibodies had a significantly higher incidence of pulmonary, joint, and renal involvement than the anti-ENA negative patients with the large speckle-like thready pattern. There was also a significantly higher incidence of Raynaud's phenomenon in patients with the thready pattern than in those with the large speckle-like thready pattern. Photosensitivity was seen significantly more frequently in the patients with the large speckle-like thready pattern than in those with the thready pattern.
