The epidemiology of microscopic colitis: a 10-year pathology-based nationwide Danish cohort study.

Objective: Microscopic colitis (MC) includes two main types: collagenous colitis (CC) and lymphocytic colitis (LC). Previous studies have indicated an increasing incidence, but these have mainly been based on regional databases. We found it important to study the epidemiology based on a comprehensive nationwide cohort.

Drug exposure and risk of microscopic colitis: a nationwide Danish case-control study with 5751 cases.

Background: Previous small studies have indicated that commonly prescribed drugs may be associated with microscopic colitis (MC). With an increasing incidence of MC, it is important to explore the association between exposure to proton pump inhibitors (PPIs), nonsteroidal anti-inflammatory drugs, statins, and selective serotonin reuptake inhibitors and MC in a larger setting.

Methods: Case-control study based on nationwide Danish registries.
