The Effects of Colchicine on the Histopathological Findings of Celiac Disease During Familial Mediterranean Fever Treatment

Familial mediterranean fever (FMF) and Celiac Disease (CD) are both autoinflammatory and autoimmune diseases with common clinical features affecting the gastrointestinal system. Familial mediterranean fever may coexist with CD. Inflammatory cells and cytokines are up-regulated within the intestinal mucosa of patients with CD. In this perspective, lymphocyte infiltration to the lamina propria of the small intestinal mucosa is a critical pathological sign. In the present study, we aimed to find out whether the treatment of an FMF patient with colchicine affects the pathological signs of concomitant developed CD on the same patient. We retrospectively reviewed the medical records of 147 patients with FMF who were followed up in our center between 2015 and 2020. Of the 147 patients with FMF, 3 patients also had CD. In this report, we presented these 3 cases. The findings obtained in this study suggest that pathological findings may be misinterpreted in autoimmune diseases, such as CD, when patients administer anti-inflammatory treatments, such as colchicine.
