Development and Validation of a Score to Assess Transmural Healing and Response in Patients with Crohn's Disease. Clin Gastroenterol Hepatol 2024:S1542-3565(24)00546-9. [PMID: 38908734 DOI: 10.1016/j.cgh.2024.06.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 06/02/2024] [Accepted: 06/04/2024] [Indexed: 06/24/2024]
Abstract
BACKGROUND & AIMS Because transmural healing (TH) could be the best therapeutic target in Crohn's disease (CD), we aimed to build and validate a score to assess TH and transmural response (TR), and to confirm their association with favorable CD outcomes. METHODS DEVISE-CD project encompassed 2 retrospective cohorts (274 and 224 patients with CD for development and validation phase, retrospectively) and 1 multicenter prospective validation cohort (N = 46 patients). A step-by-step process was used to build the modified Clermont score (C-score). The primary end points were time to bowel damage progression, and steroid-free clinical remission with fecal calprotectin <250 at 1 year for retrospective and prospective validation cohorts, respectively. RESULTS Edema, ulcer, contrast enhancement, diffusion-weighted hyperintensity, fat wrapping, bowel thickening (>3 mm), and enlarged lymph nodes were associated to higher risk of bowel damage progression (P < .01). Edema, diffusion-weighted hyperintensity, post-gadolinium contrast enhancement, and bowel thickening were highly coexistent (>95%) and collinear (P < .0001). Bowel thickness had the highest sensitivity to change after treatment (standardized mean difference = 0.30 ± 1.0; P = .001). C-score was calculated as 0.2x(bowel thickness-3mm) + 1.5x enlarged lymph nodes + 2x ulcer. TH (C-score <0.5; hazard ratio [HR], 0.28 [0.13-0.63]; P = .002; adjusted HR [aHR], 0.15 [0.04-0.53]; P = .003), TR50 (50% decrease of C-score; HR, 0.30 [0.15-0.63]; P = .001; aHR, 0.36 [0.14-0.88]; P = .025), or TR25 (25% decrease of C-score; HR, 0.37 [0.19-0.71]; P = .003; aHR, 0.46 [0.23-0.94]; P = .034) prevented bowel damage progression in development and validation cohorts, respectively. In the prospective validation cohort, achieving TH (OR, 4.6 [1.3-15.6]; P = .016), TR50 (OR, 6.9 [1.8-26.0]; P = .008), or TR25 (OR, 6.0 [1.6-22.3]; P = .008) after 12 weeks of anti-tumor necrosis factor therapy led to higher rate of corticosteroid-free remission at 1 year. CONCLUSIONS C-score is a validated, reliable, and easy-to-use tool to assess TH and TR in patients with CD.

Abstract
PURPOSE Crohn's disease (CD) is a progressive disorder leading to cumulative bowel damage. The Lémann index is a validated tool that can help in monitoring the progression of the disease and evaluating the effectiveness of different therapies. Our aim was to describe the main radiological findings in incidentally diagnosed CD and to evaluate bowel damage in this subgroup compared to patients diagnosed at later stages. METHODS Patients with an incidental diagnosis of CD during the colorectal cancer screening program were compared to controls with a CD cohort diagnosed after symptomatic onset and matched 1:1 by disease extent. All cross-sectional examinations were centrally read, performing a descriptive analysis of the main findings and calculation of Lémann index. RESULTS Thirty-eight patients were included: 19 with preclinical CD (median age 55 years (IQR, 54-62), 53% male, 74% non-smokers; 74% B1 and 26% B2) and 19 matched-controls with symptomatic CD. In those with preclinical CD, the most frequent transmural findings on MRE were contrast enhancement (79%), wall thickening (79%), followed by lymphadenopathy (68%), edema (42%), and increased vascularity (42%). Among those with strictures, controls showed a higher rate of preestenotic dilation (100% vs. 0%, p = 0.01). Bowel damage assessment revealed no statistically significant differences in the Lémann index between preclinical CD and controls (p = 0.95). A statistically significant higher score in the colonic/rectum score was observed (p = 0.014). CONCLUSION Patients with preclinical CD demonstrate similar radiological findings and degree of bowel damage as new-onset symptomatic CD.

Substantial cost savings of ultrasound-based management over magnetic resonance imaging-based management in an inflammatory bowel disease service. Scand J Gastroenterol 2024; 59:683-689. [PMID: 38501494 DOI: 10.1080/00365521.2024.2330588] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Accepted: 03/08/2024] [Indexed: 03/20/2024]
Abstract
BACKGROUND Imaging is used to monitor disease activity in small bowel Crohn's disease (CD). Magnetic Resonance Enterography is often employed as a first modality in the United Kingdom for assessment and monitoring; however, waiting times, cost, patient burden and limited access are significant. It is as yet uncertain if small bowel intestinal ultrasound (IUS) may be a quicker, more acceptable, and cheaper alternative for monitoring patients with CD. METHODS A clinical service evaluation of imaging pathways was undertaken at a single NHS site in England, United Kingdom. Data were collected about patients who were referred and underwent an imaging analysis for their IBD. Only patients who underwent a therapy change were included in the analysis. Data were collected from care episodes between 01 January 2021-30 March 2022. RESULTS A combined total of 193 patient care episodes were reviewed, 107 from the IUS pathway and 86 from the MRE pathway. Estimated costs per patient in the IUS pathway was £78.86, and £375.35 per patient in the MRE pathway. The MRE pathway had an average time from referral to treatment initiation of 91 days (SD= ±61) with patients in the IUS pathway waiting an average of 46 days (SD= ±17). CONCLUSIONS Findings from this work indicate that IUS is a potential cost-saving option when compared to MRE when used in the management of CD. This is in addition to the cost difference of the radiological modalities. A large, multicentre, prospective study is needed to validate these initial findings.

Abstract
Precision medicine is part of 5 focus areas of the Challenges in IBD Research 2024 research document, which also includes preclinical human IBD mechanisms, environmental triggers, novel technologies, and pragmatic clinical research. Building on Challenges in IBD Research 2019, the current Challenges aims to provide a comprehensive overview of current gaps in inflammatory bowel diseases (IBDs) research and deliver actionable approaches to address them with a focus on how these gaps can lead to advancements in interception, remission, and restoration for these diseases. The document is the result of multidisciplinary input from scientists, clinicians, patients, and funders, and represents a valuable resource for patient-centric research prioritization. In particular, the precision medicine section is focused on the main research gaps in elucidating how to bring the best care to the individual patient in IBD. Research gaps were identified in biomarker discovery and validation for predicting disease progression and choosing the most appropriate treatment for each patient. Other gaps were identified in making the best use of existing patient biosamples and clinical data, developing new technologies to analyze large datasets, and overcoming regulatory and payer hurdles to enable clinical use of biomarkers. To address these gaps, the Workgroup suggests focusing on thoroughly validating existing candidate biomarkers, using best-in-class data generation and analysis tools, and establishing cross-disciplinary teams to tackle regulatory hurdles as early as possible. Altogether, the precision medicine group recognizes the importance of bringing basic scientific biomarker discovery and translating it into the clinic to help improve the lives of IBD patients.

Abstract
BACKGROUND AND AIMS We explored the potential for differential efficacy of vedolizumab between early and late ulcerative colitis [UC] with evaluation of clinical, endoscopic, and histological endpoints. METHODS This was a multicentre, multinational, open-label study in patients with moderately-to-severely active UC, defining early UC by a disease duration <4 years and bio-naïve and late UC by a disease duration > 4 years and additional exposure to tumour necrosis factor antagonists. Patients received standard treatment with intravenous vedolizumab for 52 weeks [300 mg Weeks 0, 2, 6, every 8 weeks thereafter without escalation]. The primary endpoint was corticosteroid-free clinical remission with endoscopic improvement [total Mayo score ≤2 with no subscore >1] at both Weeks 26 and 52. RESULTS A total of 121 patients were included: in the "early" group, 25/59 [42.4%] achieved the primary endpoint versus 19/62 [30.6%] in the "late" group [p = 0.18]. There were no significant differences between the two groups in endoscopic improvement [Week 26: "early" 32/59 [54.2%] versus "late" 29/62 [46.8%]; p = 0.412; Week 52: 27/59 [45.8%] versus 25/62 [40.3%]; p = 0.546] or in histological remission [Robarts Histopathology Index <3 without neutrophils in the epithelium and lamina propria] [Week 26: 24/59 [40.7%] versus 21/62 [33.9%]; p = 0.439; Week 52: 22/59 [37.3%] versus 22/62 [35.5%]; p = 0.837]. CONCLUSIONS No significant differences in clinical, endoscopic, and histological outcomes were observed between "early" and "late" disease.

Abstract
BACKGROUND Crohn's disease (CD) is a progressive, destructive, and disabling disorder. Our study aimed to assess changes over time in the Lémann index (LI) and the Inflammatory Bowel Disease Disability Index (IBD-DI) in a cohort of CD patients. METHODS This was a single-center prospective cohort study of 130 consecutive CD patients with a follow-up of at least 4 years. The LI 1 and the IBD-DI 1 questionnaires were assessed in 2016 and again between September 2020 and October 2021 (LI 2 and IBD-DI 2). RESULTS Of the 130 patients with assessment of both LI 1 and IBD-DI 1, 61 had calculation of the LI 2 and 98 patients answered the IBD-DI 2 questionnaire, with a median time between the 2 evaluations of 4.2 years. The LI increased for 16 (26%), decreased for 26 (43%), and remained unchanged for 19 (31%) patients. The median LI did not change over time (9.6 vs 9.3; P = .14). Clinical disease activity was significantly associated with bowel damage progression. A high initial LI (>7.9) was not associated with CD progression (surgery, drug dose escalation, or change of biologic). The IBD-DI decreased for 59 (60.2%), increased for 37 (37.8%), and remained unchanged for 2 (2%) patients. The median IBD-DI decreased significantly over time (23.2 vs 21.4; P = .006). There was no correlation between the 2 indexes. CONCLUSIONS This is the first prospective cohort study assessing changes over time in both the LI and the IBD-DI in CD patients. After 4 years, the LI appeared to be stable and the IBD-DI decreased, with no correlation between the 2 indexes.

Abstract
Crohn's disease is a chronic inflammatory disease of the gastrointestinal tract that might lead to progressive bowel damage and disability. The exact cause of Crohn's disease is unknown, but evidence points towards multifactorial events causing dysregulation of the innate immune system in genetically susceptible people. Commonly affecting the terminal ileum and proximal colon, Crohn's disease inflammation is often discontinuous and patchy, segmental, and transmural. Identification of characteristic findings on ileocolonoscopy and histology remains the diagnostic gold standard, but complete assessment involves laboratory abnormalities, including micronutrient deficiencies, cross-sectional imaging to identify transmural disease extent, severity and complications, and a psychosocial assessment. Treatment strategies for patients with Crohn's disease now go beyond achieving clinical remission to include deeper targets of endoscopic healing and consideration of adjunctive histological and transmural targets to alter disease progression potentially further. The use of early effective advanced therapies and development of therapies targeting alternative novel pathways with improved safety profiles have resulted in a new era of healing in Crohn's disease management. Future combination of advanced therapies with diet or other biological drugs and small molecules, together with improvements in tight control monitoring tools and predictive biomarkers might continue to improve outcomes for patients with Crohn's disease.

Matrix gla protein, a potential marker of tissue remodelling and physiological ageing of the gut in crohn's disease. Scand J Gastroenterol 2024; 59:296-303. [PMID: 38411457 DOI: 10.1080/00365521.2023.2286913] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Accepted: 11/19/2023] [Indexed: 02/28/2024]
Abstract
BACKGROUND The inactive dephosphorylated and uncarboxylated form of the matrix Gla protein (dp-ucMGP) has been shown to be increased in plasma of inflammatory bowel disease (IBD) patients. Our aim was to assess if the plasmatic level of dp-ucMGP could reflect disease endoscopic activity, presence of strictures and cumulative structural bowel damage in Crohn's disease (CD) patients. METHODS The plasmatic level of dp-ucMGP was measured in a monocentric cohort of prospectively recruited patients. The analysis was done by chemiluminescent immunoassay on blood samples collected the day of a planned ileocolonoscopy. In addition to classical clinical data (gender, age, body mass index (BMI), disease duration, current treatment), endoscopic data (disease location, Crohn's Disease Endoscopic Index of Severity (CDEIS), mucosal healing (MH), presence of 9 CD lesion types) and biological markers (faecal calprotectin and C-reactive protein (CRP)) were collected. The association between dp-ucMGP level and Lémann index was also investigated. Univariate linear regression was used to investigate the relationship between dp-ucMGP level and different parameters collected. RESULTS A total of 82 ileocolonoscopies and dp-ucMGP assays were performed in 75 CD patients (45 females; 37 ileocolonic, 19 ileal and 19 colonic diseases) between October 2012 and November 2019. A total of 24 patients (29.3%) showed MH. The dp-ucMGP levels were not associated with MH, CDEIS, faecal calprotectin or CRP levels. Plasmatic dp-ucMGP levels increased significantly with age (p = 0.0032), disease duration (p = 0.0033), corticosteroids use (p = 0.019) and tended to increase in patients with intestinal strictures (p = 0.086) but not with the Lémann index. CONCLUSION The significant increase of plasmatic dp-ucMGP levels with age, disease duration and the trend observed in patients with non-ulcerated strictures may suggest that this extracellular matrix protein could be a marker of tissue remodelling and physiological ageing of the gut.

Abstract
INTRODUCTION The American Gastroenterological Association (AGA) has compiled risk factors that may be predictive of disease complications in Crohn's disease (CD) and ulcerative colitis (UC). The aim of this study was to evaluate the performance of the AGA risk factors for risk stratification in UC and CD. METHODS We included participants of 2 cohorts: the Ocean State Crohn's and Colitis Area Registry cohort and the Mayo Clinic cohort. Baseline clinical risk factors were extracted according to the AGA pathway. Our primary end point was defined as follows: (i) any inflammatory bowel disease related-hospitalization, (ii) any inflammatory bowel disease-related bowel surgery, or (iii) any progression of disease. We analyzed the association of the number of AGA risk factors with our end point. Statistical multivariable modeling was performed with Cox proportional hazards model. RESULTS A total of 412 patients with CD were included. Comparing ≥3 risk factors with 0-1 risk factor, we found a significantly increased risk of complications in both the Ocean State Crohn's and Colitis Area Registry cohort (hazard ratio [HR] 2.75, 95% confidence interval 1.71-4.41) and Mayo Clinic cohort (HR 2.07, 95% confidence interval 1.11-3.84). Diagnosis at younger age (HR 2.07), perianal disease (HR 1.99), and B2/B3 behavior (HR 1.92) were significantly associated with disease complications. We did not observe a consistent association between number of risk factors nor any specific individual risk factors and risk of disease complications in the 265 patients with UC included. DISCUSSION We found a significant association between the number of AGA risk factors and the risk of disease complication in CD; this association was not significant in UC. The presence of ≥ 3 risk factors in CD leads to the highest risk of complications. The AGA care pathway is a useful tool to stratify patients who are at higher risk of disease complications in patients with CD.

Abstract
In the ideal world prognostication or predicting disease course in any chronic condition would allow the clinician to anticipate disease behaviour, providing crucial information for the patient and data regarding best use of resources. Prognostication also allows an understanding of likely response to treatment and the risk of adverse effects of a treatment leading to withdrawal in any individual patient. Therefore, the ability to predict outcomes from the onset of disease is the key step to developing precision personalised medicine, which is the design of medical care to optimise efficiency or therapeutic benefit based on careful profiling of patients. An important corollary is to prevent unnecessary healthcare costs. This paper outlines currently available predictors of disease outcome in IBD and looks to the future which will involve the use of artificial intelligence to interrogate big data derived from various important 'omes' to tease out a more holistic approach to IBD.

Abstract
Delayed diagnosis is a challenge in the management of inflammatory bowel disease (IBD). Several studies show a significant association between diagnostic delay and disease progression to complications and surgery, especially in Crohn's disease (CD). What risk factors are associated with diagnostic delay in IBD remains unclear. In order to reduce diagnostic delay, the Red Flags Index has been developed and validated. The combination of the Red Flags Index score and non-invasive biomarkers such as fecal calprotectin seems to be highly accurate in screening patients with underlying IBD to be referred for further diagnostic workup and eventual early effective treatment strategies. Our literature review aims to obtain a comprehensive overview of the impacts of diagnostic delay in IBD on the potential risk factors associated with IBD, how diagnostic tools may be effective in reducing diagnostic delay, and future perspectives in this field.

Abstract
INTRODUCTION Cross-sectional imaging techniques including MR and CT enterography and ultrasound are integral to Crohn's disease management, accurate, responsive, and well tolerated. They assess the full thickness of the bowel wall, perienteric environment, and distant complications. As we strive toward tighter disease control, imaging's role will expand further with transmural healing becoming an increasingly important therapeutic target. AREAS COVERED MEDLINE and Web of Science were searched from 2012 to 2023 inclusive. We review the evidence for cross-sectional imaging in assessing disease activity, phenotyping, and therapeutic response assessment. Emerging novel imaging applications such as quantifying enteric motility and fibrosis, prognostication, and potential utility of artificial intelligence will be covered. Recent international consensus statements highlight the need for standardized imaging reporting and definitions of transmural healing and remission. We will discuss how recent advances may be best integrated into patient care and highlight key outstanding research questions. EXPERT OPINION Cross-sectional imaging is established in Crohn's disease management. Research emphasis should be placed on optimal integration of imaging modalities in clinical care pathways, workforce training, definitions, and evidence for use of imaging based therapeutic targets such as transmural healing, better phenotyping of stricturing disease, and developing novel techniques, including integration of artificial intelligence.

Abstract
BACKGROUND The Lémann Index [LI] and the recently updated LI are tools for measuring structural bowel damage in adults with Crohn's disease [CD] but have not been evaluated in children. We aimed to validate the updated LI in the prospective multicentre ImageKids study of paediatric CD. METHODS We included children with CD undergoing magnetic resonance enterography [MRE], pelvic magnetic resonance imaging [MRI] and ileocolonoscopy. Half were followed for 18 months, when MRE was repeated. Serum was collected for fibrosis-related proteomic markers. The LI was calculated by central readers from the MRE, ileocolonoscopy, physical examination and surgical data. Reliability and construct validity were assessed at baseline, while responsiveness and test-retest reliability were explored longitudinally. RESULTS In total, 240 children were included (mean age, 14.2 ± 2.5 years; median disease duration, 2.2 years [interquartile range, IQR 0.25-4.42]; median baseline LI, 4.23 [IQR 2.0-8.8]). The updated LI had excellent inter-observer reliability (interclass correlation coefficient [ICC] = 0.94, 95% confidence interval [CI] 0.92-0.95) but poor, although statistically significant, correlation with radiologist and gastroenterologist global assessments of damage and with serum proteomic levels of fibrotic markers [rho = 0.15-0.30, most p < 0.05]. The updated LI had low discriminative validity for detecting damage (area under the receiver operating characteristic curve [AUC-ROC] 0.69, 95% CI 0.62-0.75). In 116 repeated MREs, responsiveness was suboptimal for differentiating improved from unchanged disease [AUC-ROC 0.58, 95% CI 0.45-0.71]. Test-retest reliability was high among stable patients [ICC = 0.84, 95% CI 0.72-0.91]. CONCLUSION Overall, the updated LI had insufficient psychometric performance for recommending its use in children. An age-specific index may be needed for children with shorter disease duration than typical adult cohorts.

Abstract
Macrophages are essential for the maintenance of intestinal homeostasis, yet appear to be drivers of inflammation in the context of inflammatory bowel disease (IBD). How these peacekeepers become powerful aggressors in IBD is still unclear, but technological advances have revolutionized our understanding of many facets of their biology. In this Review, we discuss the progress made in understanding the heterogeneity of intestinal macrophages, the functions they perform in gut health and how the environment and origin can control the differentiation and longevity of these cells. We describe how these processes might change in the context of chronic inflammation and how aberrant macrophage behaviour contributes to IBD pathology, and discuss how therapeutic approaches might target dysregulated macrophages to dampen inflammation and promote mucosal healing. Finally, we set out key areas in the field of intestinal macrophage biology for which further investigation is warranted.

Abstract
Inflammatory bowel diseases (IBD) encompass two main entities including ulcerative colitis and Crohn's disease. Although having a common global pathophysiological mechanism, IBD patients are characterized by a significant interindividual heterogeneity and may differ by their disease type, disease locations, disease behaviours, disease manifestations, disease course as well as treatment needs. Indeed, although the therapeutic armamentarium for these diseases has expanded rapidly in recent years, a proportion of patients remains with a suboptimal response to medical treatment due to primary non-response, secondary loss of response or intolerance to currently available drugs. Identifying, prior to treatment initiation, which patients are likely to respond to a specific drug would improve the disease management, avoid unnecessary side effects and reduce the healthcare expenses. Precision medicine classifies individuals into subpopulations according to clinical and molecular characteristics with the objective to tailor preventative and therapeutic interventions to the characteristics of each patient. Interventions would thus be performed only on those who will benefit, sparing side effects and expense for those who will not. This review aims to summarize clinical factors, biomarkers (genetic, transcriptomic, proteomic, metabolic, radiomic or from the microbiota) and tools that could predict disease progression to guide towards a step-up or top-down strategy. Predictive factors of response or non-response to treatment will then be reviewed, followed by a discussion about the optimal dose of drug required for patients. The time at which these treatments should be administered (or rather can be stopped in case of a deep remission or in the aftermath of a surgery) will also be addressed. IBD remain biologically complex, with multifactorial etiopathology, clinical heterogeneity as well as temporal and therapeutic variabilities, which makes precision medicine especially challenging in this area. Although applied for many years in oncology, it remains an unmet medical need in IBD.

Abstract
BACKGROUND Crohn's disease (CD) and ulcerative colitis (UC) arise from a dysregulation of the balance between commensal microbiota and mucosal-associated immune system, in patients with genetic and environmental predisposition. Different pathophysiological mechanisms have been reported to influence disease history, with impact on disease phenotype and risk of complications. OBJECTIVES This review aims to summarize the definitions of early CD and UC, analyze the underlying immunological mechanisms, and evaluate the impact of recognizing and treating early inflammatory bowel disease (IBD) on patients' prognosis (short- and long-term outcomes). DESIGN To address this issue, we have performed a scoping review. DATA SOURCES AND METHODS Three online databases (MEDLINE, Web of Science, and ScienceDirect) were searched and the results were independently screened by two reviewers. RESULTS From 683 records identified, 42 manuscripts evaluating early IBD in adult patients were included. The 'early CD' concept was first described in 2008. Four years later, an international consensus proposed the definition of diagnosis up to 18 months, in patients without previous or current need for disease-modifying therapies. Several other definitions have been proposed; the '2 years since diagnosis' is the most used, regardless of disease characteristics or medication. The amount of evidence on early UC is lower and more recent. Regarding early disease pathogenesis, most theories emphasize the prominent role of innate immunity, followed by early-Th1 adaptive response. CONCLUSION The treatment of early CD seems to be crucial for the management of CD patients, impacting short-, medium-, and long-term outcomes. On the other hand, the early treatment of UC appears to be less advantageous, yet evidence comes from only a few retrospective studies.

Abstract
Endoscopy remains the reference standard for the diagnosis and assessment of patients with inflammatory bowel disease (IBD), but it has several important limitations. Cross-sectional imaging techniques such as magnetic resonance enterography (MRE) and intestinal ultrasound (IUS) are better tolerated and safer. Moreover, they can examine the entire bowel, even in patients with stenoses and/or severe inflammation. A variety of cross-sectional imaging activity scores strongly correlate with endoscopic measures of mucosal inflammation in the colon and terminal ileum. Unlike endoscopy, cross-sectional techniques allow complete visualisation of the small-bowel and assess for extraintestinal disease, which occurs in nearly half of patients with IBD. Extramural findings may predict outcomes better than endoscopic mucosal assessment, so cross-sectional techniques might help identify more relevant therapeutic targets. Coupled with their high sensitivity, these advantages have made MRE and IUS the primary non-invasive options for diagnosing and monitoring Crohn's disease; they are appropriate first-line investigations, and have become viable alternatives to colonoscopy. This review discusses cross-sectional imaging in IBD in current clinical practice as well as research lines that will define the future role of these techniques.

Abstract
BACKGROUND Crohn’s disease (CD) is a chronic inflammatory bowel disorder that progresses to bowel damage (BD) over time. An image-based index, the Lémann index (LI), has been developed to measure cumulative BD.
AIM To characterize the long-term progression of BD in CD based on changes in the LI and to determine risk factors for long-term progression.
METHODS This was a single-center longitudinal cohort study. Patients who had participated in prospective studies on the accuracy of magnetic resonance imaging using endoscopy as a gold standard and who had a follow-up of at least 5 years were re-evaluated after 5-12 years.
RESULTS Seventy-two patients were included. LI increased in 38 patients (52.8%), remained unchanged in 9 patients (12.5%), and decreased in 25 patients (34.7%). The small bowel score and surgery subscale significantly increased (P = 0.002 and P = 0.001, respectively), whereas the fistulizing subscale significantly decreased (P = 0.001). Baseline parameters associated with BD progression were ileal location (P = 0.026), CD phenotype [stricturing, fistulizing, or both (P = 0.007, P = 0.006, and P = 0.035, respectively)], disease duration > 10 years (P = 0.019), and baseline LI stricturing score (P = 0.049). No correlation was observed between BD progression and baseline clinical activity, biological markers, or severity of endoscopic lesions.
CONCLUSION BD, as assessed by the LI, progressed in half of the patients with CD over a period of 5-12 years. The main determinants of BD progression were ileal location, stricturing/fistulizing phenotype, and disease duration.

Abstract
BACKGROUND The severity of endoscopic recurrence during the first year after intestinal resection for Crohn's disease is predictive of clinical recurrence. The aim of our study was to assess the impact of the implementation of an ileocolonoscopy during the first year after surgery on surgical recurrence. METHODS All patients who underwent a first intestinal resection for Crohn's disease between 1992 and 2018 at the University Hospital of Liège were retrospectively included. The time to surgical recurrence was compared in three successive groups of patients operated on in the period 1992-2001 (group A), 2002-2011 (group B), and 2012-2020 (group C) using the Kaplan-Meier method and the Log-Rank test. To identify independent prognostic factors, a multivariate analysis was used via the Cox model. RESULTS 223 patients (group A = 69, group B = 94, group C = 60) were included. Probabilities of surgical recurrence were significantly lower in group C (2.2% and 4.7% at 3 and 5 years, respectively) compared with group B (4.2% and 7.6% at 3 and 5 years, respectively) and with group A (9% and 18.2% at 3 and 5 years, respectively) (p = 0.0089). Ileocolonoscopy during the year after surgery was associated with a significantly reduced surgical recurrence rate in univariate and multivariate analysis (HR = 0.31, p = 0.0049). CONCLUSION The implementation of an early ileocolonoscopy after surgery for Crohn's disease since early 2000 has been associated with a reduced surgical recurrence over the last 30 years.

Abstract
BACKGROUND Heterogeneity exists in reported outcomes and outcome measurement instruments [OMI] from observational studies. A core outcome set [COS] for observational and real-world evidence [RWE] in inflammatory bowel disease [IBD] will facilitate pooling large datasets. This systematic review describes and classifies clinical and patient-reported outcomes, for COS development. METHODS The systematic review of MEDLINE, EMBASE, and CINAHL databases identified observational studies published between 2000 and 2021 using the population exposure outcome [PEO] framework. Studies meeting eligibility criteria were included. After titles and abstracts screening, full-text articles were extracted by two independent reviewers. Primary and secondary outcomes with corresponding OMI were extracted and categorised in accordance with OMERACT Filter 2.1 framework. The frequency of outcomes and OMIs are described. RESULTS From 5854 studies, 315 were included: 129 [41%] Crohn's disease [CD], 60 [19%] ulcerative colitis [UC], and 126 [40%] inflammatory bowel disease [IBD] studies with 600 552 participants. Totals of 1632 outcomes and 1929 OMI were extracted mainly from medical therapy [181; 72%], surgical [34; 11%], and endoscopic [6; 2%] studies. Clinical and medical therapy-related safety were frequent outcome domains recorded in 194 and 100 studies. Medical therapy-related adverse events [n = 74] and need for surgery [n = 71] were the commonest outcomes. The most frequently reported OMI were patient or event numbers [n = 914], Harvey-Bradshaw Index [n = 45], and Montreal classification [n = 42]. CONCLUSIONS There is substantial variability in outcomes reporting and OMI types. Categorised outcomes and OMI from this review will inform a Delphi consensus on a COS for future RWE in IBD. Data collection standardisation may enhance the quality of RWE applied to decision-making.

Abstract
BACKGROUND AND AIMS The utility of real-world data is dependent on the quality and homogeneity of reporting. We aimed to develop a core outcome set for real-world studies in adult patients with inflammatory bowel disease (IBD). METHODS Candidate outcomes and outcome measures were identified and categorised in a systematic review. An international panel including patients, dietitians, epidemiologists, gastroenterologists, nurses, pathologists, radiologists and surgeons participated in a modified Delphi consensus process. A consensus meeting was held to ratify the final core outcome set. RESULTS A total of 26 panellists from 13 countries participated in the consensus process. A total of 271 items (130 outcomes, 141 outcome measures) in nine study domains were included in the first-round survey. Panellists agreed that real-world studies on disease activity should report clinical, endoscopic and biomarker disease activity. A disease-specific clinical index (Harvey-Bradshaw Index, Partial Mayo Score, Simple Clinical Colitis Activity Index) should be used, rather than physician global assessment. In ulcerative colitis (UC), either the UC Endoscopic Index of Severity or the Mayo Endoscopic Score can be used, but there was no consensus on an endoscopic index for Crohn's disease, nor was there consensus on the use of the presence of ulcers. There was consensus on using faecal calprotectin and C-reactive protein. There was no consensus on the use of histology in real-world studies. CONCLUSIONS A core outcome set for real-world studies in IBD has been developed based on international multidisciplinary consensus. Its adoption will facilitate synthesis in the generation of real-world evidence.

Abstract
BACKGROUND Owing to growing number of therapeutic options with similar efficacy and safety, we compared the acceptability of therapeutic maintenance regimens in inflammatory bowel disease (IBD). METHODS From a nationwide study (24 public or private centers), IBD patients were consecutively included for 6 weeks. A dedicated questionnaire including acceptability numerical scales (ANS) ranging from 0 to 10 (highest acceptability) was administered to both patients and related physicians. RESULTS Among 1850 included patients (65.9% with Crohn's disease), the ANS were 8.68 ± 2.52 for oral route (first choice in 65.8%), 7.67 ± 2.94 for subcutaneous injections (first choice in 21.4%), and 6.79 ± 3.31 for intravenous infusions (first choice in 12.8%; P < .001 for each comparison). In biologic-naïve patients (n = 315), the most accepted maintenance regimens were oral intake once (ANS = 8.8 ± 2.2) or twice (ANS = 6.9 ± 3.4) daily and subcutaneous injections every 12 or 8 weeks (ANS = 7.9 ± 3.0 and ANS = 7.2 ± 3.2, respectively). Among 342 patients with prior exposure to subcutaneous biologics, the preferred regimens were subcutaneous injections (≥2 week-intervals; ANS between 9.1 ± 2.3 and 8.1 ± 2.7) and oral intake once daily (ANS = 7.7 ± 3.2); although it was subcutaneous injections every 12 or 8 weeks (ANS = 8.4 ± 3.0 and ANS = 8.1 ± 3.0, respectively) and oral intake once daily (ANS = 7.6 ± 3.1) in case of prior exposure to intravenous biologics (n = 1181). The impact of usual therapeutic escalation or de-escalation was mild (effect size <0.5). From patients' acceptability perspective, superiority and noninferiority cutoff values should be 15% and 5%, respectively. CONCLUSIONS Although oral intake is overall preferred, acceptability is highly impacted by the rhythm of administration and prior medication exposures. However, SC treatment with long intervals between 2 injections (≥8 weeks) and oral intake once daily seems to be the most accepted modalities.

Abstract
Increasing insights into the immunopathogenesis of inflammatory bowel diseases [IBD] have led to the advent of targeted therapies that inhibit crucial mediators of the inflammatory process, thereby widening our available therapeutic armamentarium. Anti-tumour necrosis factor [anti-TNF] agents are still a mainstay of our therapeutic endeavours and the introduction of corresponding biosimilars has further widened their use. Nevertheless, only a subgroup of treated patients benefit from the initiated treatment and there is secondary non-response in the course of therapy. Initiation of subsequent therapy often poses a challenge to the treating physician, as non-response to primary anti-TNF treatment generally characterizes a patient group that is more treatment-resistant, which may be due to the immunological impregnation by prior anti-TNF exposure. At present, there is currently no guidance for the most appropriate second-line therapy after anti-TNF failure. Here, we review the efficacy of secondary biological therapy in anti-TNF-treated patients. We focus on and assess available clinical trial data of the emerging substance class of IL-23p19 inhibitors, which have demonstrated remarkable efficacy not only in anti-TNF-naïve but also refractory patients. We present molecular mechanisms that drive IL-23-mediated resistance to ongoing anti-TNF therapy and discuss the dynamic fluidity of the mucosal cytokine network in the course of therapy that perpetuates the mucosal inflammatory reaction. Translation of these findings into clinical practice might finally lead to initiation of the most appropriate therapy at the right time of the individual disease course, which would have important implications for the patient's probability of response to treatment.

Breaking through the biologic therapy efficacy plateau for inflammatory bowel disease requires the strategic development of personalized biomarkers in the tight control model. After risk stratification early in the disease course, targeted serial monitoring consistently to assess clinical outcomes in response to therapy allows for quick therapeutic adjustments before bowel damage can occur. Point-of-care intestinal ultrasound performed by the treating gastroenterologist is an accurate cross- sectional biomarker that monitors intestinal inflammation in real-time, enhances patient care, and increases shared understanding to help achieve common treatment goals. Combining intestinal ultrasound during a clinic visit with existing serum and stool biomarkers in a home testing setup with electronic health monitoring allows for an optimized, patient-centered personalized treatment algorithm that may improve treatment outcomes. Here, we review the current state, pragmatic considerations, and future implications of point-of-care testing and home testing for noninvasive inflammatory bowel disease monitoring in the tight control model.

Abstract
Ulcerative colitis (UC) has been characterized by inflammation limited to the mucosa. Although sustained and durable remission has been associated with mucosal healing, the recurrent phenomenon of persistent clinical disease activity despite mucosal healing has been observed in clinical practice and across pivotal trials. Over time, UC appears to confer an increased risk of progression, defined as changes of disease phenotype; adverse transmural effects on the bowel wall; increased risk of neoplasia development; worsening colorectal function; and increased risk of colectomy, hospitalizations, and other extraintestinal comorbidities. Although the treatment paradigm for Crohn's disease has shifted toward early aggressive intervention to prevent disease progression and irreversible bowel damage, such urgency in efforts to halt disease progression in UC have been largely overlooked. This review summarizes the multiple facets of UC contributing to a modified perception of the disease as a progressive one. We propose further study of the natural history and priorities for further treatment goals that include these considerations.

Abstract
Cutaneous damage caused by hidradenitis suppurativa is an important contributor to disease burden, independent of active lesions. Outcome measures used to specifically assess damage are becoming commonplace in assessment of inflammatory diseases. However, no standardized method for assessing HS damage currently exists. The purpose of this study was to review outcome measures in HS that include constructs of both active disease and damage, review damage-specific instruments used in other inflammatory and destructive diseases, and review instruments used to assess scars of various etiologies. This ultimately provides insight into how attributes of different tools can be applied to develop an outcome measure specific to HS damage.

Abstract
BACKGROUND Crohn's disease (CD) is a chronic inflammatory disorder affecting the gastrointestinal tract with disease behaviour based on the depth and severity of mucosal injury. Cumulative injury can result in complications including stricture formation and penetrating complications which often require surgical resection of diseased segments of the intestine resulting in significant morbidity. Accurate assessment of disease activity and appropriate treatment is essential in preventing complications. SUMMARY Treatment targets in the management of CD have evolved with the advent of more potent immunosuppressive therapy. Targeting the resolution of sub-clinical inflammation and achieving mucosal healing is associated with the prevention of stricturing and penetrating complications. Identifying non-invasive modalities to assess mucosal healing remains a challenge. KEY MESSAGES Mucosal healing minimizes the risk of developing disease complications, prolongs steroid-free survival, and reduces hospitalization and the need for surgical intervention.
