The prevalence of autoimmune thyroid diseases (AITD) is estimated to be about 5%. AITD are generally of low severity, but can affect significantly the quality of life, and they are a cause of considerable medical costs. The AITD comprise two main clinical presentations, Gravesâ�� disease and Hashimotoâ��s thyroiditis, whose clinical features are thyrotoxicosis and hypothyroidism, respectively. AITD is characterized by lymphocytic infiltration of the thyroid parenchyma; recruited T helper 1 lymphocytes are responsible of IFN-�³ and TNF-�± secretion, which stimulates CXCL10 (the main IFN-�³-inducible chemokines) production from the thyroid cells, generating an amplification feedback loop, that induces the autoimmune process. Epidemiological data show an interaction among environmental triggers and genetic susceptibility as the key factor leading to the initiation of AITD. An association of AITD and papillary thyroid cancer has been suggested. Moreover, AITD have been shown to be associated with other autoimune disorders (type 1 diabetes, Sj�¶grenâ��s syndrome, rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, cryoglobulinemia, etc). These above mentioned data suggest that AITD patients need to be monitored for the appearence of thyroid dysfunctions, thyroid nodules, or other autoimmune disorders.
