Quera R, Núñez F P. Are we ready to use new endoscopic scores for ulcerative colitis? World J Gastroenterol 2024; 30:1466-1469.

Abstract
For ulcerative colitis (UC), the variability in inflammatory activity along the colon poses a challenge in management. The focus on achieving endoscopic healing in UC is evident, where the UC Endoscopic Index of Severity and Mayo Endoscopic Subscore are commonly used for evaluation. However, these indices primarily consider the most severely affected region. Liu et al recent study validates the Toronto Inflammatory Bowel Disease Global Endoscopic Reporting (TIGER) score offering a comprehensive assessment of inflammatory activity across diverse segments of the colon and rectum and a reliable index correlating strongly with UC Endoscopic Index of Severity and moderately with Mayo Endoscopic Subscore (MES). Despite recommendation, certain aspects warrant further investigation. Fecal calprotectin, an intermediate target, correlates with TIGER and should be explored. Determining TIGER scores defining endoscopic remission and response, evaluating agreement with histological activity, and assessing inter-endoscopist agreement for TIGER require scrutiny. Exploring the correlation between TIGER and intestinal ultrasound, akin to MES, adds value.

Abstract
Background Artificial intelligence (AI)-assisted colonoscopy systems with contact microscopy capabilities have been reported previously; however, no studies regarding the clinical use of a commercially available system in patients with ulcerative colitis (UC) have been reported. In this study, the diagnostic performance of an AI-assisted ultra-magnifying colonoscopy system for histological healing was compared with that of conventional light non-magnifying endoscopic evaluation in patients with UC. Methods The data of 52 patients with UC were retrospectively analyzed. The Mayo endoscopic score (MES) was determined by 3 endoscopists. Using the AI system, healing of the same spot assessed via MES was defined as a predicted Geboes score (GS) < 3.1. The GS was then determined using pathology specimens from the same site. Results A total of 191 sites were evaluated, including 159 with a GS < 3.1. The MES diagnosis identified 130 sites as MES0. A total of 120 sites were determined to have healed based on AI. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of MES0 for the diagnosis of GS < 3.1 were 79.2%, 90.6%, 97.7%, 46.8%, and 81.2%, respectively. The AI system performed similarly to MES for the diagnosis of GS < 3.1: sensitivity, 74.2%; specificity: 93.8%; PPV: 98.3%; NPV: 42.3%; and accuracy: 77.5%. The AI system also significantly identified a GS of < 3.1 in the setting of MES1 (P = .0169). Conclusions The histological diagnostic yield the MES- and AI-assisted diagnoses was comparable. Healing decisions using AI may avoid the need for histological examinations.

Advanced technology for assessment of endoscopic and histological activity in ulcerative colitis: a systematic review and meta-analysis. Therap Adv Gastroenterol 2022; 15:17562848221092594. [PMID: 35509428 PMCID: PMC9058346 DOI: 10.1177/17562848221092594] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Accepted: 03/17/2022] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Advanced 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. METHODS We 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. RESULTS A 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]. CONCLUSION Activity 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.

Abstract
Background Mucosal healing (MH) evaluated by endoscopy is a novel target of therapy in UC as it is associated with improved long-term outcomes. It is defined based on the Mayo endoscopic score (MES), but it is still to define whether a value of MES 0 or 1 should be the target. The purpose of this paper is to present the results of a systematic review with meta-analysis which compares long-term outcomes of patients in steroid-free clinical remission with MES 0 with those with MES 1. Methods A systematic electronic search of the literature was performed using Medline, Scopus, and CENTRAL through December 2020 (PROSPERO n:CRD42020179333). The studies concerned UC patients, in steroid-free clinical remission, with MES of 0 or 1, and with at least 12-months of follow-up. Results Out of 4611 citations, 15 eligible studies were identified. Increases in clinical relapse among patients with MES 1 were observed in all the studies included in this review, suggesting that MES of 1 have a higher risk of relapse than a score of 0. MES 0 patients displayed a lower risk of clinical relapse (OR 0.33; 95% CI 0.26–0.43; I2 13%) irrespective of the follow-up time (12-months or longer). On the other hand, no differences were found comparing MES 0 versus MES 1 about the risk of hospitalization or colectomy. Conclusions MES 0 is associated with a lower rate of clinical relapse than is MES 1. For this reason, MES 0, rather than MES 0–1, should be considered the therapeutic target for patients with UC.

Abstract
OBJECTIVES Pediatric ulcerative colitis (UC) is characterized by low sustained remission rates and frequent extension of disease even if clinical remission is obtained with therapy. Moderate-to-severe endoscopic activity is a risk factor for relapse while prospective evidence regarding early mucosal healing or persistence of inflammation after remission in children is not available. Our aim was to evaluate if significant inflammation is common after clinical remission and could explain the high relapse rate in pediatric UC. METHODS Pediatric UC patients with clinical remission, defined as pediatric UC activity index (PUCAI) scores <10, were prospectively assessed for mucosal healing by endoscopy 3 to 5 months after remission was documented. Mayo score was assessed for each segment by a blinded adult gastroenterologist using central reading. Symptomatic patients before sigmoidoscopy were excluded. Sustained remission was assessed retrospectively at 18 months follow-up. RESULTS Forty-two children were screened, 28 children in continuous clinical remission at time of sigmoidoscopy were included. Mayo 0 was present in 12/28 (42.86%), Mayo 1 in 2/28 (7.1%) and Mayo 2 to 3 in 14/28 (50.0%) endoscopies. Among 23 patients with follow-up through 18 months, remission was sustained in 6/12 (50.0%) with Mayo score 0 to 1 versus 2/11 (18.18%) of patients with Mayo 2 and 3. CONCLUSIONS Over 50% of children assessed for mucosal healing 3 to 5 months after clinical remission is obtained, have endoscopic disease, primarily moderate-to-severe Mayo 2 to 3 inflammation, which was associated with lower sustained remission.

Abstract
Background and study aims: Endoscopy plays an essential role in managing patients with ulcerative colitis (UC), as it allows us to visualize and assess the severity of the disease. As such assessments are not always objective, different scores have been devised to standardize the findings. The main aim of this study was to assess the interobserver variability between the Mayo Endoscopy Score (MES), Ulcerative Colitis Endoscopy Index of Severity (UCEIS) and Ulcerative Colitis Colonoscopy Index of Severity (UCCIS) analyzing the severity of the endoscopic lesions in patients with ulcerative colitis. Patients and methods: This was a single-cohort observational study in which a colonoscopy was carried out on patients with UC, as normal clinical practice, and a video was recorded. The results from the video were classified according to the MES, UCEIS and UCCIS by three endoscopic specialists independently, and they were compared to each other. The Mayo Endoscopy Score (MES) was used to assess the clinical situation of the patient. The therapeutic impact was analyzed after colonoscopy was carried out. Results: Sixty-seven patients were included in the study. The average age was 51 (SD ± 16.7) and the average MES was 3.07 (SD ± 2.54). The weighted Kappa index between endoscopists A and B for the MES was 0.8; between A and C 0.52; and between B and C 0.49. The intraclass correlation coefficient for UCEIS was 0.92 among the three endoscopists (CI 95 %: 0.83-0.96) and 0.96 for UCCIS among the three endoscopists (CI 95 % 0.94-0.97). A change in treatment for 34.3 % of the patients was implemented on seeing the results of the colonoscopy. Conclusions: There was an adequate, but not perfect, correlation between the different endoscopists for MES, UCEIS, UCCIS. This was higher with the last two scores. Thus, there is still some subjectivity to be minimized through special training, on assessing the seriousness of the endoscopic lesions in patients with UC.

Abstract
INTRODUCTION Faecal calprotectin [FC] is a reliable surrogate marker for disease activity in ulcerative colitis [UC]; however, there are no consensus cut-off values for remission. The study aim was to correlate FC with Mayo Endoscopic Score [MES] and histological disease activity of UC patients in clinical remission. METHODS Our study recruited adult UC patients at the McGill IBD Center between 2013 and 2017. Patients in clinical remission [partial Mayo score ≤2], undergoing endoscopy for disease activity or dysplasia surveillance, were enrolled. Before bowel preparation, FC was collected. MES was documented during colonoscopy. Biopsies were taken; histological activity was assessed using Geboes score and the presence of basal plasmacytosis. RESULTS A total of 185 patients were recruited. The area under the curve [AUC] in receiver operating characteristic [ROC] analysis to predict MES 1-3 [from 0] was 0.743 [95% CI 0.67-0.82; p <0.001] with an FC cut-off value 170 µg/g [64% sensitivity, 74% specificity], and to predict MES 2-3 [from 0-1] was 0.722 [95% CI 0.61-0.83; p <0.001] with an FC cut-off value 170 µg/g [69% sensitivity, 65% specificity]. To differentiate MES 0 from MES 1, an FC value 130 µg/g yields a 70% sensitivity and 68% specificity. The AUC in ROC analysis to predict Geboes <3.1 was 0.627 [95% CI 0.55-0.71; p = 0.003], with an FC value 135 µg/g [54% sensitivity, 69% specificity]. CONCLUSIONS In this large study, FC ≥170 µg/g predicts endoscopic activity and FC ≥135 µg/g predicts histological activity. Therefore in clinical practice, lower faecal calprotectin thresholds can be chosen to optimise identification of patients with ongoing endoscopic and histological disease activity.

Abstract
BACKGROUND AND AIMS Histological healing may be the ultimate therapeutic goal in ulcerative colitis [UC]. We investigated, for the first time, the association between vedolizumab trough levels and histological healing in UC. METHODS This is a single-centre retrospective cohort study including all consecutive UC patients on vedolizumab maintenance therapy who had a histological evaluation blindly to clinical data and underwent therapeutic drug monitoring, between June 2014 and March 2018. Per-event analysis was performed. Histological healing was defined as a Nancy histological index ≤1. RESULTS Thirty-five histological samples were analysed. Median [interquartile range] vedolizumab trough levels were higher in the group with histological healing (31.5 [25-49.1] μg/mL) compared with the group without histological healing (15 [9-26.6] μg/mL, p = 0.02). The higher vedolizumab trough level quartiles tended to be associated with greater rates of histological healing [p = 0.10]. A cut-off vedolizumab trough level of 25 μg/mL predicted histological healing with an accuracy of 74% and an area under the receiver operating curve of 0.62 [95% confidence interval 0.58-0.92, p = 0.004]. Bivariate analysis identified a vedolizumab trough level ≥25 µg/mL [p = 0.006], a partial Mayo score ≤1 [p = 0.008], C-reactive protein level <5 mg/L [p = 0.005] and a Mayo endoscopic subscore ≤1 [p = 0.0004] as factors associated with histological healing. CONCLUSIONS Histological healing was associated with higher vedolizumab trough levels during maintenance therapy in UC. A vedolizumab trough level threshold of 25 μg/mL proved most optimal to predict histological healing according to the Nancy histological index. Confirmation of these data in larger, independent cohorts is needed.

Abstract
The current goals of treatment in inflammatory bowel disease, both Crohn's disease and ulcerative colitis, are to achieve clinical, endoscopic and ideally histological remission and improve the quality of life of these patients. Current therapies are effective in achieving remission in most cases, but there is a lack of clear guidelines on their optimal duration. This review aims to evaluate the current evidence on the withdrawal of therapy with 5-aminosalicylates, thiopurines and methotrexate. We also aim to identify which specific group of patients, while in remission and in the absence of risk factors, may be able to discontinue therapy without a significant risk of relapse.

Abstract
BACKGROUND AND AIMS Endoscopy and histopathology are pivotal for evaluating disease activity in ulcerative colitis [UC]; correlation between validated endoscopic and histological indices has not been examined. We aim to correlate the Ulcerative Colitis Endoscopic Index of Severity [UCEIS] with two new validated histological indices in patients with established UC. METHODS This was a single-centre cohort of patients with established UC, who underwent flexible sigmoidoscopy or colonoscopy by a single endoscopist. The UCEIS was scored at the worst affected area in the distal colon, which was biopsied; histological disease activity using Nancy [NI] and Robarts' Histological [RHI] indices was scored by a pathologist blinded to the endoscopy. Spearman correlation between the UCEIS, NI, and RHI, and between NI and RHI, was performed. RESULTS A total of 125 patients, median age 37 years [range 16-81 years], with UCEIS scores [scale 0-8]: 0, n = 21; 1-3, n = 48; 4-6, n = 51; and 7-8, n = 5, were included. Correlation coefficients between UCEIS and NI [scale 0-4] were r = 0.84 (95% confidence interval [CI] 0.76-0.89, p < 0.001) and between UCEIS and RHI [scale 0-33] r = 0.86 [95% CI 0.80-0.90, p < 0.001]. The difference in correlation was not significant [p = 0.57]. There was excellent correlation between the two histological indices [r = 0.92, 95% CI 0.87-0.95, p < 0.001]. Quiescent disease activity defined as the absence of neutrophils [Nancy 0-1, Robarts 0-3] was most closely correlated with UCEIS = 0. CONCLUSIONS The UCEIS strongly correlates with both NI and RHI. Complete mucosal healing is best defined as a UCEIS = 0/8, since this correlates with the absence of microscopic disease activity.
