| [ Summary ] |
Abnormalities in the immune regulating system are strongly related to the onset and development of inflammatory bowel disease (IBD). The inflammasome is a multiprotein oligomer consisting of caspase 1, PYCARD, NALP and occasionally caspase 5, which promotes the maturation of interleukin 1β (IL-1β) and IL-18. Activation of inflammasome by exogenous and endogenous stimuli is associated with various diseases such as familial Mediterranean fever. We report on a case involving a forty two years old woman diagnosed with colitis related to familial Mediterranean fever (MEFV) gene mutation. She was refractory to conventional IBD treatment, but responded to colchicine administration. Based on our experience, we describe the importance of examining MEFV gene patients with differential diagnoses of IBD. |
