A systematic review and meta-analysis of artificial intelligence-diagnosed endoscopic remission in ulcerative colitis.

ABSTRACT: Endoscopic remission is an important therapeutic goal in ulcerative colitis (UC). The Ulcerative Colitis Endoscopic Index of Severity (UCEIS) and Mayo Endoscopic Score (MES) are the commonly used endoscopic scoring criteria. This systematic review and meta-analysis aimed to evaluate the accuracy of artificial intelligence (AI) in diagnosing endoscopic remission in UC. We also performed a meta-analysis of each of the four endoscopic remission criteria (UCEIS = 0, MES = 0, UCEIS = <1, MES = <1). Eighteen studies involving 13,687 patients were included. The combined sensitivity and specificity of AI for diagnosing endoscopic remission in UC was 87% (95% confidence interval [CI]:81-92%) and 92% (95% CI: 89-94%), respectively. The area under the curve (AUC) was 0.96 (95% CI: 0.94-0.97). The results showed that the AI model performed well regardless of which criteria were used to define endoscopic remission of UC.

Project description:BackgroundClinical remission is the recommended treatment target in ulcerative colitis. The predictors and outcomes of achieving histologic remission within a treat-to-target paradigm are not well established.AimTo evaluate the predictors and outcomes of achieving histologic remission in patients with ulcerative colitis treated-to-target of endoscopic healing (modified Mayo endoscopy score 0 or 1).MethodsWe conducted a retrospective cohort study in adults with active ulcerative colitis (modified Mayo endoscopy score 2 or 3), whose treatment was iteratively optimised to achieve endoscopic healing. We identified predictors of achieving histologic remission, and outcomes (risk of symptomatic relapse, and ulcerative colitis-related hospitalisation and/or surgery) of achieving histologic remission vs persistent histologic activity, using Cox proportional hazard analysis.ResultsOf the 411 patients with clinically active ulcerative colitis, 270 achieved endoscopic healing. Of the 270 patients, 55% simultaneously achieved histologic remission. Depth of endoscopic healing at final endoscopic assessment was the only independent determinant of histologic remission (modified Mayo endoscopy score 0 vs 1: odds ratio, 0.31 [95% confidence intervals, 0.18-0.52]). Over 28 months, achieving histologic remission was associated with a lower risk of clinical relapse (1-year cumulative risk: 18.7% vs 29.5%; adjusted hazard ratio, 0.56 [0.37-0.85]), and lower risk of hospitalisation (hazard ratio, 0.44 [0.20-0.94]). The incremental benefit of achieving histologic remission was observed only in patients achieving Mayo endoscopy score 1, but not Mayo endoscopy score 0.ConclusionsIn patients with active ulcerative colitis treated-to-target of endoscopic healing, 55% simultaneously achieved histologic remission. Histologic remission, particularly in patients achieving modified Mayo endoscopy score 1, was associated with favourable outcomes. Treating to a target of histologic remission over endoscopic healing requires prospective evaluation.

Project description:BackgroundAdvanced endoscopic technologies led to significant progress in the definition of endoscopic remission of ulcerative colitis (UC) and correlate better with histological changes, compared with standard endoscopy. However, while studies have assessed the diagnostic accuracy of endoscope technologies individually, there are currently limited data comparing between technologies. As such, the aim of this systematic review was to pool data from the existing literature and compare the correlations between endoscopy and histologic disease activity scores across endoscope technologies.MethodsWe searched PubMed and Embase until February 2021 for eligible studies reporting the correlation between endoscopy and histology activity scores in UC. Studies were grouped by endoscope technology as standard-definition white light (SD-WLE), high-definition white light (HD-WLE) or electronic virtual chromoendoscopy (VCE) and comparisons made between these groups.ResultsA total of N = 27 studies were identified, of which N = 12 were included in a meta-analysis of correlations between endoscopic and histological activity scores. Combining these studies identified considerable heterogeneity (I 2: 89-93%) and returned a pooled correlation coefficient (ρ) for the SD-WLE group of 0.74, which did not differ significantly from HD-WLE (ρ: 0.65, p = 0.521) or VCE (ρ: 0.70, p = 0.801). In addition, N = 4 studies reported the accuracy of endoscopic activity scores on WLE and VCE to diagnose histological remission. Pooling these found significantly higher accuracy for VCE, compared with WLE [risk ratio: 1.13, 95% confidence interval (CI): 1.07-1.19, p < 0.001].ConclusionActivity scores assessed using endoscopy are strongly correlated with activity on histology regardless of endoscopic technology. VCE seems to be more accurate in predicting histological remission than WLE. However, given the heterogeneity between the included studies, head-to-head trials are warranted to confirm these findings.
