Clinical and laboratory test data of 77 patients with systemic lupus erythematosus (SLE) were evaluated by factor analysis. Six factors representing disease patterns were extracted: cutaneous symptoms of alopecia, malar rash, rash and photosensitivity; renal involvement; the anticoagulant syndrome of phlebitis and partial thromboplastic time inversely related to platelet count; lymphopenia; viral or fibromyalgia symptoms of headache, nervousness, joint and muscle pain; and serology of anti-DNA antibodies and complement inversely related. Application of factor analysis reveals various clinical presentations of SLE.
