<abstract xmlns="http://www.w3.org/1999/xhtml"><p> Fatigue is a common feature in a wide variety of chronic inflammatory and autoimmune diseases, but fatigue in autoimmune thyroid disease (AITD) has not been investigated so far.

This cross-sectional clinical study included 62 patients with increased concentrations of thyroperoxidase antibodies (TPOAbs) as confirmation of AITD and 52 healthy individuals who were negative for thyroid antibodies; all controls were euthyroid.
