Their results, which were published in the February issue of Digestive Diseases and Sciences, show that the prevalence of celiac disease is 3.4% in patients with autoimmune thyroiditis, compared with 0.6% and 0.25% among the two control groups. They also found a connection between untreated celiac disease, gluten consumption, and autoimmune disorders. The researchers believe that undiagnosed celiac disease can cause other disorders by switching on some as yet unknown immunological mechanism. Untreated celiac patients produce organ-specific autoantibodies. Further, By following these subjects longitudinally, it has been seen that not only do the anti-gliadin antibodies and anti-endomysium antibodies disappear after 3 to 6 months of a gluten-free diet, but so do the organ-specific autoantibodies.
In conclusion the Italian researchers suggest that patients with autoimmune thyroiditis could benefit from a screening for celiac disease, which could eliminate the symptoms and limit the risk of developing other autoimmune disorders.
