Development of a Microscopic Colitis Disease Activity Index: A Prospective Cohort Study

Image for November 2017 Hot TopicMicroscopic colitis (MC) is a common cause of chronic diarrhoea, often with additional symptoms. No validated instruments exist to assess disease activity in MC, making it difficult to compare efficacy of treatments between clinical trials. Mayo Clinic researchers aimed to identify clinical features that independently predicted disease severity and to create a microscopic colitis disease activity index (MCDAI). Patients with MC were prospectively administered a survey assessing their GI symptoms and the IBD questionnaire (IBDQ). A single investigator also scored a physician global assessment (PGA) of disease severity on a 10-point scale. Multiple linear regression identified which symptoms best predicted the PGA. These symptoms were then combined in a weighted formula to create the MCDAI. The relationship between MCDAI and the IBDQ was investigated. The MCDAI strongly predicted the PGA and correlated with a validated measure of quality of life. Several symptoms in addition to diarrhoea are associated with disease severity in MC. The study was published in Gut.
