[Autoantibodies Against Histones and Actin Determined by Western Blotting in Patients with Rheumatic Diseases]

Using the Western blot method, the authors analyzed 85 sera obtained from patients with rheumatic diseases, focused on the presence of antihistones and antiactin autoantibodies. The authors detected a 32% incidence of the two investigated autoantibody specificities. In a group of 42 patients with systemic lupus erythematosus in 22 sera (52%) positive antihistone antibodies were present, whereby autoantibodies anti-H1 and anti-H2B were most frequent. In 15 sera in this group of patients (36%) antiactin autoantibodies were present.
