[Leukocyte migration inhibition test in lupus erythematosus and dermatomyositis].

The Leucocyte-Migration-Inhibition-Test was performed to examine 10 patients with Systemic Lupus Erythematosus (SLE), 10 patients with Discoid Lupus Erythematosus (DLE) and 4 patients with Dermatomyositis for evidence of cell-mediated immunity to RNA, DNA, human muscle antigen and collagen human type I. Our results support, that cell-mediated immunity plays a pathogenic role in both diseases. Patients with SLE show a correlation between activity of disease, Leucocyte-Migration-Inhibition to DNA and DNA-binding-activity of serum. Muscle-antigen is an obvious relevant partner of reaction of cellular immunity in patients with Dermatomyositis.
