Background: Selenium (Se) is a crucial micronutrient for thyroid gland homeostasis. Acting through iodothyronine deiodinases, it regulates thyroid hormones synthesis and by glutathione peroxidases removes harmful free radicals. The Se role in pathogenesis of autoimmune thyroiditis is currently under investigation. Se supplementation decreases antithyroid antibodies during pregnancy, may prevent from postpartum thyroiditis and is approved for treatment of mild Graves’ opht...

Background: Selenium (Se) sufficiency is beneficial for thyroid metabolism and pregnancy course due to its antioxidant and anti-inflammatory properties.

Despite lacking or conflicting recommendations for its supplementation in pregnancy, Se is used in a clinical setting, as a common constituent of multivitamin pregnancy diet supplemen...

Introduction: Subclinical hyperthyroidism (SH) affects about 1% of world human population at least. The diagnosis of this disease leans on the laboratory criteria only: decreased of TSH and normal FT3 and FT4 concentrations.

These symptoms are anticipated by increasing of left ventricular walls thickness and its mass index.<p class=...
