IgG-class insulin autoantibodies in autoimmune thyroid disease.
We studied the incidence of insulin autoantibodies (IAA) in 97 patients with autoimmune thyroid disease with an enzyme-linked immunosorbent assay. The sera were also tested for islet cell antibodies (ICA) and thyrotropin receptor antibodies (TRAb). IAA as assessed by a standard deviation score were present in 7 patients (7.2%). None of the patients were seropositive for ICA. Data from this random sampling and a retrospective study of 12 patients on antithyroid drug treatment indicated that the presence of IAA was not associated with TRAb.
