Summary

We attempt to clarify the serum leucine-rich α 2-glycoprotein (LRG) level which can predict histologic remission in ulcerative colitis patients in this study. Colonoscopy with histology will be performed when histologic remission is predicted, irrespective of symptoms or serum LRG values. Serum LRG levels are analyzed by an enzyme-linked immunosorbent assay.

Detailed description

Aim: Serum leucine-rich α 2-glycoprotein (LRG) may be a noninvasive biomarker for monitoring disease activity in patients with ulcerative colitis (UC). We attempt to clarify the LRG level which predicts histologic remission in UC patients in this study. Methods: Patients with UC were consecutively enrolled with the measurement of serum LRG. Colonoscopy with histology is performed when histologic remission is predicted, irrespective of symptoms or serum LRG values. Serum LRG levels are analyzed by an enzyme-linked immunosorbent assay. For the evaluation of UC activity, clinical remission was defined as score 1 or 0 using the partial Mayo score and endoscopic remission was defined as score 0 using the Mayo endoscopic subscore. And histologic remission is defined as \< grade 2 using Geboes score. We analyze the area under receiver operating characteristic (ROC) curves to evaluate the diagnostic ability of LRG for predicting histologic remission of UC.
