Blood biomarkers reflect integration of severity and extent of endoscopic inflammation in ulcerative colitis

摘要

Background and AimBlood markers are not always regarded as satisfactory surrogate biomarkers for predicting endoscopic activity in ulcerative colitis (UC). However, those biomarkers have been evaluated solely based on endoscopic activity at the most severe colorectal location, taking no account of the extent of inflammation. This study aimed to examine whether integrated evaluation of severity and extent of endoscopic activity improves the performance of blood biomarkers for UC.
