(en) Microscopic colitis (MC), including collagenous colitis (CC) and lymphocytic colitis (LC), has emerged as a common cause of chronic diarrhea with an annual overall incidence of 4.14 per 100,000 person-years (CC) and 4.85 per 100,000 person-years (LC), respectively. While most patients experience an indolent disease course with occasional relapses, it undeniably affects their quality of life. No curative therapy exists, but most patients respond well to budesonide, which represents the treatment of choice with up to 90% achieving clinical remission after induction therapy.
