Abstract:
Introduction: A micronutrient called selenium; a non-metallic element is necessary to manufacture selenoproteins, including selenocysteine. The thyroid has the highest concentration of selenium per gram of tissue in people. The majority of known selenoproteins, including glutathione peroxidase, are expressed in the thyroid and are crucial for the metabolism of thyroid hormones, control of redox states, and preservation of cellular homeostasis. It has been demonstrated that selenium therapy for Graves orbitopathy patients can slow the disease's course and enhance the quality of life. Different selenium supplements have demonstrated varying anticancer efficacy in thyroid cancer. It also looked at how different treatment plans affected patients' thyroid function, mood, and inflammatory markers. TSH (thyroid-stimulating hormone) is slightly elevated in subclinical hypothyroidism, while T4 or T3 levels are normal.
Objective: The purpose of this study was to evaluate the therapeutic effects of levothyroxine sodium given alone or in combination with selenium on patients with chronic lymphocytic thyroiditis and hypothyroidism to serve as a guide for clinical treatment. The purpose of the current study is to ascertain the impact of selenium supplementation on thyroid hormone and anti-thyroid peroxidase antibody (anti-TPO AB) levels. The pathophysiology of this illness may be affected by the imbalance in the activity of T cells such as Th1, Th2, Th17, and Treg. This study was to evaluate any changes in the release of cytokines by these cells after selenium administration in patients with HT. The diagnosis and management of thyroid problems during pregnancy are covered in detail in this article. It also includes a summary of the main recommendations made by several medical associations for the diagnosis, treatment, and interpretation of thyroid function during pregnancy.
Results: The combined group's overall effective rate was much greater than the control group's. After therapy, both groups' TT3, TT4, TSH, TgAb, and TPOAb levels, SAS and SDS scores, and levels of inflammatory mediators such as IL-2, IL-10, and TNF- all showed a significant improvement. In the combination group, IL-10 levels increased more, and TGAb, TPOAb, IL-2, TNF-, SAS, and SDS scores reduced more when compared to the control group, whereas the differences in the other indices were not statistically significant. According to research, LT4 has some efficacy in treating CLT with hypothyroidism, and selenium therapy in combination with LT4 can increase its therapeutic effect and help patients' immunological and inflammatory responses as well as their mood.
Conclusions: Myo-inositol, vitamin D, and selenium supplementation together had an impact on the decline in cytokine markers, Ab-TPO, and Ab-TG levels, which helped to compensate for the underlying condition. Since myricetin is a strong inducer of HATC cell death, it may be helpful in the creation of HATC therapeutic medicines. Myricetin significantly reduced the growth of HATC cells, by almost 70%. A significant number of dead cells showed sub-G1 phase arrest. In SNU-80 HATC cells, myricetin similarly displayed cytotoxicity and caused DNA condensation in a dose-dependent manner. Additionally, myricetin induced the mitochondria to release apoptosis-inducing factor (AIF) into the cytoplasm and changed the potential of the mitochondrial membrane.
