BACKGROUND: Hashimoto's thyroiditis is an autoimmune thyroid disorder. Lymphocytic colitis and collagenous colitis are characterized by diarrhea with normal endoscopic findings. Autoimmune disorders are common in Hashimoto's thyroiditis and lymphocytic colitis. The aim of this study was to investigate the incidence of lymphocytic colitis in patients with Hashimoto's thyroiditis
Link here:CONCLUSIONS: There was a higher incidence of histologic findings of lymphocytic colitis in patients with Hashimoto's thyroiditis, although most of the patients were clinically asymptomatic. This finding suggests that lymphocytic colitis may have an asymptomatic clinical course and should encourage further clinical investigations to better anticipate the relationship between autoimmune disorders.
