Overview of the mothers and children enrolled in the analysis. The group of mothers was finally divided into three groups of healthy women and mothers with different thyroid diseases, and the group of newborns consisted of a few twins and a majority of singletons. HT group comprised 15 patients with concomitant AIT, including euthyroid subjects on levothyroxine; one child from twin pregnancy had insufficient cord blood volume to perform the analysis. In terms of the related mothers and newborns calculations, 101 pairs were included in the analyses. AIT—autoimmune thyroiditis; HT—hypothyroidism; TSH—thyrotropin; fT4—free tetraiodothyronine; fT3—free triiodothyronine; TRAb—autoantibodies to TSH-receptor; a-TPO—autoantibodies to thyreoperoxidase; a-Tg—autoantibodies to thyroglobulin; Se—selenium; SELENOP—selenoprotein P; GPX3—plasma glutathione peroxidase.
