Thyroid Peroxidase Antibodies in Non-Autoimmune Hyperthyroidism Treated with Radioactive Iodine.

Earlier studies suggest increased serum levels of thyroid peroxidase antibodies (TPOAb) in some cases with non-autoimmune hyperthyroidism. The aim of the study was to assess the incidence of hypothyroidism in patients with nodular toxic goitre and toxic adenoma at 12 months after radioactive iodine therapy in the relation to TPOAb levels. The study comprised 100 patients (83 females; 17 males) treated with radioactive iodine therapy.
