 Chronic nonspecific multiple ulcers of the small intestine is a hereditary enteropathy characterized by persistent blood and protein loss. It is sometimes challenging to distinguish CEAS(chronic enteropathy associated with SLCO2A1 gene)from CD(Crohn's disease)because both diseases are primarily characterized by multiple small intestinal ulcers. However, it is unrealistic to conduct genetic screening for all patients suspected of having CD or CEAS. This study investigated whether PGE-MUM(prostaglandin E-major urinary metabolites)are useful for distinguishing CEAS from CD. In total, 20 patients with CEAS and 98 patients with CD were enrolled in this study. PGE-MUM concentration in patients with CEAS was found to be significantly higher than that in patients with CD(median, 102.7 vs. 27.9μg/g×Cre ; p<0.0001). ROC curve analysis revealed that the optimal PGE-MUM cutoff value for distinguishing CEAS from CD was 48.9μg/g×Cre with 95.0% sensitivity and 79.6% specificity. Therefore, PGE-MUM measurement can be considered a useful test for distinguishing CEAS from CD.
