High Serum IgG4 Concentrations in Patients with Hashimoto's Thyroiditis.

Purpose. Since recent reports suggest that Hashimoto thyroiditis (HT) may be associated with IgG4-related disease, we aimed to find out whether the measurement of serum IgG4 allows for the identification of distinct types of HT, with different clinical, sonographic, and serologic characteristics. Methods.

Decreased Expression of Thyroglobulin and Sodium Iodide Symporter Genes in Hashimoto's Thyroiditis.

Aim. The aim of the study was to compare the expression of sodium iodide symporter (NIS), thyroglobulin (Tg), tumor necrosis factor- α (TNF α ), and interleukin-1 β genes in patients with Hashimoto's thyroiditis (HT) and healthy individuals. Subjects and Methods.
