Abstract:
Objective To observed the impact of selenium supplementation therapy on the thyroid perioxidase antibody(TPO-Ab) levels and serum oxidative stress[malondialdehyde(MDA, glutathione peroxidase(GPx), and superoxide dismutase(SOD)] in patients with Hashimoto′s thyroiditis. Methods 79 patients with Hashimoto′s thyroiditis were randomly divided into trial group(n=44) and placebo group(n=35) .The double-blind treatment was for 24 weeks. The thyroid hormone levels, serum TPO-Ab levels, and oxidative stress indexes(MDA, GPx, and SOD) of both groups were detected before and after treatment. Results (1)There was no change of thyroid hormone levels either before or after treatments of both groups(P>0.05). (2)TPO-Ab of the trial group decreased significantly after the treatment(P<0.05). While the placebo group has little change. Group with TPO-Ab≤200 IU/ml and the course≤1 year manifested the most obvious declines by 29.98% and 26.63% respectively. (3)The oxidative stress level of trial group significantly decreased after 24 weeks. There was significantly positive correlation between the oxidative stress indexes and TPO-Ab. However the placebo group was with little change. Conclusion Selenium supplementation may reduce the level of TPO-Ab titers and oxidative stress in patients with Hashimoto′s thyroiditis, especially for those with lower antibody titers and short course.
