Predictors of endoscopic inflammation in patients with ulcerative colitis in clinical remission.

ABSTRACT: Patients with ulcerative colitis (UC) who are in clinical remission may still have underlying endoscopic inflammation, which is associated with inferior clinical outcomes. The goal of this study was to determine the prevalence of active endoscopic disease, and factors associated with it, in patients with UC who are in clinical remission.Prospective observational study in a single center. Patients with UC in clinical remission (by Simple Clinical Colitis Activity Index) were enrolled prospectively at the time of surveillance colonoscopy. Disease phenotype, endoscopic activity (Mayo subscore), and histologic score (Geboes) were recorded, and blood was drawn for peripheral blood biomarkers.Overall, 149 patients in clinical remission were prospectively enrolled in this cohort; 81% had been in clinical remission for >6 months, and 86% were currently prescribed maintenance medications. At endoscopy, 45% of patients in clinical remission had any endoscopic inflammation (Mayo endoscopy subscore >0), and 13% had scores >1. In a multivariate model, variables independently associated with a Mayo endoscopic score >1 were remission for <6 months (P = 0.001), white blood count (P = 0.01), and C-reactive protein level (P = 0.009). A model combining these 3 variables had a sensitivity of 94% and a specificity of 73% for predicting moderate-to-severe endoscopic activity in patients in clinical remission (area under the curve, 0.86). In an unselected subgroup of patients who had peripheral blood mononuclear cell messenger RNA profiling, GATA3 messenger RNA levels were significantly higher in patients with endoscopic activity.Duration of clinical remission, white blood count, and C-reactive protein level can predict the probability of ongoing endoscopic activity, despite clinical remission in patients with UC. These parameters could be used to identify patients who require intensification of treatment to achieve mucosal healing.

Project description:BackgroundThe significance of endoscopic evaluation in the diagnosis and management of ulcerative colitis (UC) has been widely recognized. Over the years, scholars have established several endoscopic scores. Herein, we assessed the clinical application value of the Mayo Endoscopic Subscore (Mayo ES), the Degree of Ulcerative Colitis Burden of Luminal Inflammation (DUBLIN) score, and the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) score in UC patients, by comparing their correlation with disease activity and their predictive potential for treatment response and clinical outcomes.MethodsUC patients hospitalized from September 2015 to September 2019 were retrospectively analysed. We employed Spearman's rank correlation coefficient to assess the linear association of the assessed endoscopic scores with the clinical parameters. The receiver-operating characteristic curve was applied to evaluate the predictive capabilities of the endoscopic scores for treatment escalation and 1-year readmission.ResultsA total of 178 patients were enrolled; most of them (82%) suffered moderate or severe colitis. Among them, 48 (27%) patients received treatment escalation and 59 (33%) were readmitted within 1 year. The DUBLIN and UCEIS scores demonstrated higher correlations with clinical parameters than the Mayo ES. The DUBLIN scores significantly differed between patients with mild, moderate, and severe colitis (all P < 0.001). The UCEIS scores demonstrated the best predictabilities for treatment escalation and 1-year readmission with an area under the curve of 0.88 and 0.75, respectively. Compared to the UCEIS and DUBLIN scores, the predictive capabilities of the Mayo ES for treatment escalation (both P < 0.001) and 1-year readmission (P < 0.001 and P = 0.002, respectively) were lower. The UCEIS scores exhibited a significant difference between the steroid-responsive group and the steroid-dependent or steroid-refractory group (both P < 0.001), while no significant differences in the Mayo ES and DUBLIN scores were found among the three groups (both P > 0.05).ConclusionThis study demonstrates that both the DUBLIN and UCEIS scores outperform the Mayo ES in assessing disease severity and predicting treatment response and clinical outcomes in UC patients.
