Abstract

Irisin is a newly identified myokine secreted by skeletal muscle and has significant effects on body metabolism. Thyroidal functional state has a profound influence on the metabolism of human body. Therefore, the aim of this study was to investigate the possible changes in serum irisin concentrations before and after treatment in hypothyroid subjects. The study included 26 patients with overt hypothyroidism due to Hashimoto thyroiditis and 19 healthy subjects. Baseline serum thyroid function tests and presence of thyroid autoantibodies and levels of creatine kinase (CK) and irisin were measured in both groups. All measurements in the hypothyroid group were repeated after euthyroidism was achieved. Serum irisin levels were significantly lower in the hypothyroid groups than the control group (p < 0.001). Negative correlation between irisin and thyroid stimulating hormone and CK levels (r = - 0.623, p < 0.001 and r = - 0.389, p = 0.008, respectively) and a positive correlation between irisin and free thyroxine (fT4) levels (r = 0.570, p < 0.001) was found. Serum CK levels decreased significantly after treatment (p < 0.001). Serum irisin levels significantly increased (from 57.4 to 99.8 U/L, p < 0.001) when the hypothyroid patients...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.
