Ehsan Alijani, Neda Abbasi

Background: Selenium forms a significant component of seleno-proteins in the body. Seleno-methionine is integrated into proteins instead of methionine and acts as a storage pool. In proteins, the active form of Selenium is seleno-cysteine.in this review we aim to prevail the results of selenium effect on thyroid status in recent clinical trials. The systemic review aims to find out the correlation between supplementation of Selenium and anti-TPO antibodies and T4 levels in Hashimoto’s Thyroiditis. Selenium supplementation decreases the level of anti-TPO antibodies. The supplementation of Selenium increases the level of T4 levels.
Methods: The mean and standard deviation (SD) of all 8 studies was were calculated. One of the researches had all the information in figures, and only the levels of anti-TPO antibodies and FT4 were obtained. Heterogenicity was estimated using I2.
Results: The p-value calculated for Anti-TPO by SPSS of the eight groups had a p-value of 0.142. The p-value calculated for T4 levels by SPSS of the five groups had a p-value of 0.239. The heterogenicity test was zero after the I2 test. The studies that were included in the systematic review were assessed by Prisma diagram and selected among the articles resulted from search keywords selenium and anti TPO and hashimotho thyroiditis on different data sources. All the participants were evaluated by sex, ages, duration of the study and the levels of anti TPO AB and thyroxin (t4) and then using SPSS software to deploy metanalysis in the systematic review.
Conclusion: In 6 of 8 studies it was a relation of selenium and thyroid status, whereas 2 studies were not. As we ran meta analysis on the data we realized that there is not significant desired effect from selenium on thyroid antibodies against previous metanalysis done by other researchers.
