Association of Thyroid Autoimmunity and Chronic Urticaria
Increase prevalence of thyroid autoimmunity is found in patients with chronic urticaria. About 5-34% of chronic urticaria patients is associated with the presence of thyroid autoimmunity who are euthyroid status whereas 5-10% of them with either hyperthyroidism or hypothyroidism.

There is no such report on the association of thyroid autoantibodies and chronic urticaria in Taiwan population yet. This study is designed to investigate the prevalence of thyroid autoimmunity associated with chronic urticaria in Taiwanese population. In addition, we intend to find out the change in the level of thyroid autoimmunity after the treatment in order to further understand their relationship. We also intend to find out the prognostic parameters in patients with the presence of thyroid autoimmunity and chronic urticaria.
