Increased serum interleukin-37 (IL-37) levels correlate with oxidative stress parameters in Hashimoto’s thyroiditis

Purpose Interleukin-37 (IL-37), member of the IL-1 family, is a natural suppressor of immune and inflammatory responses. Increased serum IL-37 levels were observed in several autoimmune diseases, including Graves’ disease. To our knowledge, no data on Hashimoto’s thyroiditis (HT) are available in the literature.
