Association between Thyroid Autoimmunity and Fibromyalgia

Experimental and Clinical Endocrinology & Diabetes, 05/02/2012

In the study, euthyroid fibromyalgia (FM) patients showed significantly higher prevalence of positive thyroperoxidase antibody (TPO Ab), as compared to age and sex matched healthy control. However, TPO Ab positivity was relatively low and not associated with the clinical manifestations in euthyroid FM patients. This finding support thyroid autoimmunity may influence the development of FM, but the evidence which support that FM is related to autoimmune etiology is not clear, and FM severity may not be affected by the presence of thyroid autoantibody.
