Autoantibodies against histones and actin in patients with rheumatic diseases assessed by the western blot method.
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.
