Microsomal and thyroglobulin autoantibody activity was detected in synovial fluid from 34 of 50 patients with various arthritides (rheumatoid arthritis, ankylosing spondylitis, osteoarthrosis, and gout). Serum from only 4 of these patients showed thyroid-autoantibody activity and the serum titers were considerably lower than the synovial-fluid titers. Thyroid autoantibody is probably produced locally in the joints of these patients.
