Importance of Se deficiency as druggable risk factor for AID. (A) High thyroid disease prevalence (pathol. Thyroid; goiter, (sub-) clinical hypothyroidism or autoimmune thyroiditis) is observed under low baseline Se intake. (B) The population on low Se intake (Ningshan) had an almost twice-higher incidence of thyroid disease as compared to the population with higher Se intake (Ziyang). (C) During pregnancy, Se status in the pregnant mothers decline from trimester 1 (Trim 1) to Trim 3, causing a severe Se deficit (<45 µg/L) in one-third of pregnancies in a European observational study. (D) Supplemental Se during pregnancy was capable of suppressing the high incidence of postpartum thyroid dysfunction (PPTD) and permanent hypothyroidism (PHT) in predisposed women ca. two-fold.
