Collagenous and lymphocytic colitis: evaluation of clinical and histological features, response to treatment, and long-term follow-up

Abstract

CC and LC share a similar clinical picture and have a benign course with long-term cessation of diarrhea in more than 70% of patients. Mesalazine and budesonide seem to be good options as first-line treatment in LC and CC, respectively. Cholestyramine may be a good alternative in patients with concomitant bile acid malabsorption.
