Abstract

Iodine deficiency (even moderate) plays a major role in pregnancy associated goiter development, which is only party reversible after pregnancy. The prevalence of post partum thyroiditis is reported to be slightly lower in areas of iodine deficiency. Thus iodine supplementation may be effective in decreasing pregnancy associated increase in thyroid volume, but enhances the risk of increasing the prevalence of thyroid dysfunction in the post partum period. Therefore, we evaluated the effect of iodine supplementation (with two different doses: 50 microg and 250 microg) on the prevalence of post partum thyroiditis and the decrease in thyroid volume up to 8 months post partum in an area of mild iodine deficiency. Thyroid volume of 56 women was evaluated 5 days and 3 months after delivery (study I). In an intervention study (Study II) 70 women were randomized to receive 50 or 250 microg of potassium iodide for a period of 8 months post partum beginning five days after delivery. Thyroid volume, the echogenecity of the thyroid gland, thyroid hormone parameters (T4, T3, fT4, TSH) and thyroid antibodies (TPO and Tg-Ab) were measured 5 days, 3 and 8 months after delivery. A total number of 11 women developed postpartum thyroid dysfunctio...Continue Reading

Autoimmune Thyroiditis

Autoimmune thyroiditis is an inflammatory disease of thyroid gland due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-cells and thyroid autoantibodies. Discover the latest research on autoimmune thyroiditis here.
