Popis: The significantly higher incidence rates of microscopic colitis (MC) in Denmark compared to Sweden remains unexplained.Consecutive patients with newly diagnosed MC in the neighbouring regions of Skåne in 2011-2015 and Zealand in 2010-2016 were prospectively identified. Data on large bowel endoscopies and biopsies rates were retrieved. Information on putative factors were obtained from registers and literature. Interobserver agreement between pathologists from both regions on 40 blinded hematoxylin and eosin (HE)-stained colon biopsies (collagenous colitis (CC), lymphocytic colitis (LC), non-specific inflammation and normal) was evaluated using kappa statistics.The mean annual incidence per 10The incidence of MC and number of cases per colonic biopsy was higher in Zealand and could not be readily explained by endoscopy or biopsy rates, differences in histological assessment or putative risk factors.
