Mayo Endoscopic Score (MES) as a reference for the histological active disease of ulcerative colitis

Abstract

Background: The degree of inflammation dramatically affects the morbidity of ulcerative colitis. Local and systemic inflammation features are modalities to determine disease severity and evaluation. Furthermore, local inflammation can be seen from endoscopic and histological examinations. This study aimed to examine the relationship of histological inflammatory profile with endoscopic scoring in ulcerative colitis patients. Method: A retrospective study was conducted using colonoscopic and histologic data from 68 ulcerative colitis patients. The endoscopic grade was assessed based on the Mayo Endoscopic Score (MES). The histological grade was analyzed using a microscope by assessing acute and chronic inflammatory cells and the presence of ulceration and crypt changes based on the Nancy Score Index and Geboes Score Index. Furthermore, the analysis test used Spearman and Mann-Whitney. Results: There is a significant positive relationship between endoscopic and histology scoring. The Nancy Score Index and MES combination yields 95% CI: 0.000-0.043, p=0.000, Correlation coefficient (r)=0.810, and odds ratio (OR)=3.272. Meanwhile, the combination of the Geboes Score Index with MES yields 95% CI: 0.000-0.043; p=0.000; r=0.727; and OR=1.347. In each histological scoring, there was a significant difference between the Nancy Score Index and Geboes Score Index tα (r = 0.018; p<0.05). Conclusion: There is a significant relationship between histological and endoscopic scoring. Therefore, an endoscopic examination can be a reference for histologically active disease.
