The current study intends to assess the impact of oral selenium intake on anti-Tg antibody in individuals with autoimmune hypothyroidism.
In this double-blinded randomized controlled trial, two groups of 72 autoimmune hypothyroid patients were randomly assigned; one group received levothyroxine (LT4) and oral selenium and the other group was given placebo with LT4. Anti-Tg antibody, free T4, anti-TPO antibody, and TSH were identified in both groups before the treatment and also 3 months after treatment and analysis of data was done by SPSS software.
After the intervention, the average amount of anti-Tg antibody decreased in both of the groups, and this decrease was noticeably greater in the intervention group (P = 0.03). In the intervention group, the TSH level decreased after the intervention (p < 0.05), and the free T4 level increased after the intervention (p < 0.05); the changes in these two variables were statistically significant.
Consumption of selenium, compared to placebo, in patients with autoimmune hypothyroidism drastically reduces the level of anti-Tg antibody, and it significantly increases the free T4 level. Also, there is a greater decrease in the level of TSH compared to the control group.
本研究旨在评估口服硒对自身免疫性甲状腺功能减退患者抗Tg抗体的影响。
在这项双盲随机对照试验中，将两组各72名自身免疫性甲状腺功能减退患者随机分组；一组接受左甲状腺素（LT4）和口服硒，另一组接受LT4加安慰剂。在治疗前及治疗3个月后对两组患者的抗Tg抗体、游离T4、抗TPO抗体和促甲状腺激素进行检测，并使用SPSS软件进行数据分析。
干预后，两组患者的抗Tg抗体平均量均下降，且干预组的下降更为明显（P = 0.03）。干预组干预后促甲状腺激素水平下降（p < 0.05），游离T4水平升高（p < 0.05）；这两个变量的变化具有统计学意义。
与安慰剂相比，自身免疫性甲状腺功能减退患者服用硒可显著降低抗Tg抗体水平，并显著提高游离T4水平。此外，与对照组相比，促甲状腺激素水平下降幅度更大。
