View clinical trials related to Autoimmune Thyroiditis.
Filter by:Our aim is to investigate if selenium supplementation versus placebo adjuvant to the standard treatment with levothyroxine (LT4) in patients with autoimmune thyroiditis will lead to improved thyroid specific quality of life, and reduced autoimmune activity. The trial will include 472 participants (2 X 236) from four clinical trial sites.
The purpose of this study is to evaluate whether low-level Laser therapy is effective in ameliorating the thyroid function of patients with hypothyroidism caused by chronic autoimmune thyroiditis.
Selenium suppresses autoimmune destruction of thyrocytes and decreases titers of serum TPOAb in AIT patients. Older 4 clinical trials approved the efficacy of the daily dose of 200micg. It's believed that Se saturates the deficient stores of GPX so GPX saves the thyrocytes against to oxidative stresses. Although less than 70 micg/d is sufficient to maximize GPX activity, none of the authors tested the doses less than 200 micg/d. Our hypothesis was that If 100 micg/d can not suppress the TPOAb titers,it means autoimmune destruction can not be blocked by saturation of deficient stores of GPX solely and the mechanism of action requires more than repletion of deficient stores. It's important not only to estimate the optimal dose but to understand the mechanism of action. High dose therapy may also suppress TPOAb levels in Se-non-deficient AIT patients, if it is so, Se therapy may becomes the solely treatment modality which can suppress the autoimmunity in more than 400 million AIT patients. Because there've been no way to suppress autoimmune war and replacement of LT4 had been the only treatment modality for palliation. An other independent part of the study is to test the effect of Se in adolescent AIT patients.
