The catalytic role of iodine excess in loss of homeostasis in autoimmune thyroiditisDuntas, Leonidas H.Current Opinion in Endocrinology, Diabetes and Obesity: October 2018 - Volume 25 - Issue 5 - p 347–352 doi: 10.1097/MED.0000000000000425 THYROID: Edited by Lewis E. Braverman and Angela M. Leung Abstract Author Information Purpose of review To review the latest developments concerning the role of iodine in the pathophysiology of autoimmune thyroiditis. Recent findings Recent studies have provided evidence that in areas with excess iodine intake, increased incidence of autoimmune thyroiditis marked by high titers of thyroid peroxidase and thyroglobulin antibodies has occurred. Investigations in the NOD.H2h4 mouse, a strain prone to AIT, showed that they are better adapted to the Wolff–Chaikoff effect. Summary To provide an overview of the studies conducted during the last few years implicating iodine in the development and manifestation of autoimmune thyroiditis.
