53 Long term follow up of microscopic colitis

Background Microscopic colitis ( MC) has been increasingly diagnosed in recent years. The two main variants are lymphocytic colitis (LC) and collagenous colitis (CC). Aim To evaluate the long term natural history and follow-up of patients diagnosed with MC. Method Patients diagnosed with MC were identified from the histopathology department database in our institution. Clinical details were obtained through a combination of chart review and follow up telephone interview. Results Conclusions MC is commonly associated with other autoimmune conditions. A significant proportion of patients had no follow-up/did not seek follow-up which raises the possibility that their symptoms were not problematic. Further follow-up of patients with MC is necessary to gain better insight into the natural history of this condition.
