RESUMEN
BACKGROUND AND AIMS: Perianal fistulation is a challenging phenotype of Crohn's disease with significant impact on quality of life. Historically, fistulae have been classified anatomically in relation to the sphincter complex, and management guidelines have been generalised, with lack of attention to the clinical heterogenicity seen. The recent 'TOpClass classification system' for perianal fistulising Crohn's disease (PFCD) addresses this issue, and classifies patients into defined groups, which provide a focus for fistula management that aligns with disease characteristics and patient goals. In this article, we discuss the clinical applicability of the TOpClass model and provide direction on its use in clinical practice. METHODS: An international group of perianal clinicians participated in an expert consensus to define how the TOpClass system can be incorporated into real-life practice. This included gastroenterologists, IBD surgeons, and radiologists specialised in PFCD. The process was informed by the multi-disciplinary team management of eight high-volume fistula centres in North America, Europe, and Australia. RESULTS: The process produced position statements to accompany the classification system and guide PFCD management. The statements range from the management of patients with quiescent perianal disease to those with severe PFCD requiring diverting-ostomy and/or proctectomy. The optimisation of medical therapies, as well as the use of surgery, in fistula closure and symptom management is explored across each classification group. CONCLUSION: This article provides an overview of the system's use in clinical practice. It aims to enable clinicians to have a pragmatic and patient-goal centred approach to medical and surgical management options for individual patients with PFCD.
RESUMEN
Patients with inflammatory bowel disease (IBD) are at increased risk of colorectal cancer (CRC), and this risk increases dramatically in those who develop low-grade dysplasia (LGD). However, there is currently no accurate way to risk-stratify patients with LGD, leading to both over- and under-treatment of cancer risk. Here we show that the burden of somatic copy number alterations (CNAs) within resected LGD lesions strongly predicts future cancer development. We performed a retrospective multi-centre validated case-control study of n=122 patients (40 progressors, 82 non-progressors, 270 LGD regions). Low coverage whole genome sequencing revealed CNA burden was significantly higher in progressors than non-progressors (p=2×10-6 in discovery cohort) and was a very significant predictor of CRC risk in univariate analysis (odds ratio = 36; p=9×10-7), outperforming existing clinical risk factors such as lesion size, shape and focality. Optimal risk prediction was achieved with a multivariate model combining CNA burden with the known clinical risk factor of incomplete LGD resection. The measurement of CNAs in LGD lesions is a robust, low-cost and rapidly translatable predictor of CRC risk in IBD that can be used to direct management and so prevent CRC in high-risk individuals whilst sparing those at low-risk from unnecessary intervention.
RESUMEN
BACKGROUND & AIMS: Vedolizumab is indicated for the treatment of chronic pouchitis in the European Union. We assessed whether vedolizumab induced mucosal healing (MH) and if MH was associated with clinical improvements. METHODS: EARNEST, a randomized, double-blind, placebo-controlled study, evaluated vedolizumab efficacy and safety in adults with chronic pouchitis. Centrally read endoscopic and histologic evaluation was performed at baseline, Week (W)14, and W34. Ulcer count, adapted Simple Endoscopic Score for Crohn's Disease in the pouch, and Pouchitis Disease Activity Index histologic component were evaluated. Pouchitis Disease Activity Index and Inflammatory Bowel Disease Questionnaire remission at W14 and W34 were compared by MH status at W14. RESULTS: Following treatment, mean (standard deviation) number of ulcers in vedolizumab-treated patients reduced from 15.1 (16.4) to 5.0 (4.9) at W14 and 2.7 (3.2) at W34 versus placebo-treated patients with corresponding values of 11.8 (11.3), 13.4 (18.4), and 9.7 (13.8) (vedolizumab vs placebo difference [95% confidence interval]: W14: -8.4 [-14.3 to -2.6]; W34: -7.0 [-12.0 to -2.0]). More patients receiving vedolizumab versus placebo achieved reduction in ulcerated pouch surface area (W14: 52.4% vs 20.0%; difference, 32.4 percentage points [p.p] [9.7, 51.4]; W34: 52.1% vs 12.9%; difference, 40.2p.p [15.6, 60.3]), absence of ulceration (W14: 23.8% vs 7.5%; difference, 16.3p.p [1.1, 31.6]; W34: 34.4% vs 15.6%; difference, 18.8p.p [-2.0, 39.5]), Simple Endoscopic Score for Crohn's Disease remission (W14: 23.8% vs 7.5%; difference, 16.3p.p [1.1, 31.6]; W34: 34.4% vs 15.6%; difference, 18.8p.p [-2.0, 39.5]), and MH (W14: 16.7% vs 2.5%; difference, 14.2p.p [1.9, 26.4]). Patients with MH at W14 had higher rates of Pouchitis Disease Activity Index and Inflammatory Bowel Disease Questionnaire remission at W14 and W34 than those without. CONCLUSIONS: Vedolizumab induced endoscopic improvements in patients with chronic pouchitis, which was associated with improved outcomes at W34, particularly in patients achieving MH at W14.

RESUMEN
BACKGROUND: Patients (20%-50%) with inflammatory bowel disease (IBD) experience chronic abdominal pain during remission. The clinical features of IBD patients with abdominal pain during remission remain poorly characterized. This cross-sectional pilot study aimed to assess patient recruitment, adherence, and feedback to optimize questionnaires for future use and to determine the clinical features that distinguish IBD patients in remission with and without abdominal pain. METHODS: Online validated questionnaires about disease activity, symptoms, and psychological factors were sent to participants of the UK National Institute for Health and Care Research (NIHR) IBD BioResource, which is a national research platform consisting of re-callable IBD patients designed to expedite research into Crohn's and colitis. Inclusion/exclusion criteria of the IBD BioResource main cohort were applied. Descriptive and inferential statistics were applied to participants in remission. p-values ≤0.01 were considered significant. KEY RESULTS: A total of 2050 patients were approached; 291 (14.2%) of these agreed to participate. In 35 patients, technical problems, length, and poor understanding of the relevance of some questionnaires affected completion as confirmed by feedback. In total, 244 patients were full responders with 122 (50%) in remission; 33 (27%) of these had chronic abdominal pain. Comparison of those with versus without (n = 89) chronic abdominal pain yielded higher scores in patients with pain for the following: somatization (p < 0.001); gastrointestinal symptoms rating scale score (p = <0.001); highly sensitive person scale (p = 0.007); catastrophizing score (p = 0.010). Trends were observed for azathioprine use (p = 0.021); coping resources inventory health in general (p = 0.046); neuroticism (p = 0.019); and poor sleep (p = 0.03). CONCLUSIONS & INFERENCES: Differences in symptoms and psychological characteristics exist between IBD patients in remission with and without abdominal pain. Confirmation of findings in larger studies may facilitate development of personalized chronic pain treatments for IBD patients.
RESUMEN
BACKGROUND: Understanding disease burden is imperative for improving inflammatory bowel disease (IBD) management. This real-world survey investigated residual disease burden and treatment satisfaction among European patients with moderate-to-severe ulcerative colitis (UC) and Crohn's disease (CD). METHODS: The Adelphi Real World IBD Disease Specific Programme was a multinational, cross-sectional survey with retrospective collection of patient- and physician-reported data on disease burden and management. Between October 2020 and March 2021, participating gastroenterologists recruited their next 7 (UC) and 8 (CD) eligible patients and reported demographics and clinical characteristics. Patients completed symptom, health-related quality of life (HRQoL), and treatment satisfaction questionnaires. Data were adjusted for confounding variables and compared between patients in remission (clinical remission, endoscopic remission, or both) and not in remission. RESULTS: Overall, 1040 patients (UC, nâ =â 502; CD, nâ =â 538) were included. Although most patients were in remission (UC, 66.1%; CD, 69.5%), most still reported symptoms (UC, 63.7%; CD, 74.1%), including flatulence, fatigue/tiredness, and abdominal pain/distension. In UC, there were no significant differences in the likelihood of experiencing 7 of 23 symptoms between patients in remission and not in remission. In CD, there was no significant difference in 19 of 23 symptoms between patients in remission and not in remission. Several symptoms were significantly associated with reduced HRQoL. HRQoL was significantly better among patients in remission than not in remission. CONCLUSIONS: Patients with IBD, both in remission and not in remission, experience residual symptoms that impair HRQoL. Comprehensive endpoints, incorporating HRQoL and patients' perspectives, and improved treatments are needed to address residual disease and patients' needs.
This real-world study investigated the residual burden of inflammatory bowel disease on European patients. We found that patientsincluding those in remissionexperience significant symptomatic burden and impaired quality of life, highlighting gaps in current therapeutics and patients' unmet needs.
RESUMEN
BACKGROUND & AIMS: Perianal fistulizing Crohn's disease (PFCD)-associated anorectal and fistula cancers are rare but often devastating diagnoses. However, given the low incidence and consequent lack of data and clinical trials in the field, there is little to no guidance on screening and management of these cancers. To inform clinical practice, we developed consensus guidelines on PFCD-associated anorectal and fistula cancers by multidisciplinary experts from the international TOpClass consortium. METHODS: We conducted a systematic review by standard methodology, using the Newcastle-Ottawa Scale quality assessment tool. We subsequently developed consensus statements using a Delphi consensus approach. RESULTS: Of 561 articles identified, 110 were eligible, and 76 articles were included. The overall quality of evidence was low. The TOpClass consortium reached consensus on 6 structured statements addressing screening, risk assessment, and management of PFCD-associated anorectal and fistula cancers. Patients with long-standing (>10 years) PFCD should be considered at small but increased risk of developing perianal cancer, including squamous cell carcinoma of the anus and anorectal carcinoma. Risk factors for squamous cell carcinoma of the anus, notably human papilloma virus, should be considered. New, refractory, or progressive perianal symptoms should prompt evaluation for fistula cancer. There was no consensus on timing or frequency of screening in patients with asymptomatic perianal fistula. Multiple modalities may be required for diagnosis, including an examination under anesthesia with biopsy. Multidisciplinary team efforts were deemed central to the management of fistula cancers. CONCLUSIONS: Inflammatory bowel disease clinicians should be aware of the risk of PFCD-associated anorectal and fistula cancers in all patients with PFCD. The TOpClass consortium consensus statements outlined herein offer guidance in managing this challenging scenario.
RESUMEN
Background: Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the most established restorative operative approach for patients with ulcerative colitis. It has associated morbidity and the potential for major repercussions on quality of life. As such, patient selection is crucial to its success. The main aim of this paper is to present an institutional preoperative checklist to support clinical risk assessment and patient selection in those considering IPAA. Methods: A literature review was performed to identify the risk factors associated with surgical complications, decreased functional outcomes/quality of life, and pouch failure after IPAA. Based on this, a preliminary checklist was devised and modified through an iterative process. This was then evaluated by a consensus group comprising the pouch multidisciplinary team (MDT) core members. Results: The final preoperative checklist includes assessment for risk factors such as gender, advanced age, obesity, comorbidities, sphincteric impairment, Crohn's disease and pelvic radiation therapy. In addition, essential steps in the decision-making process, such as pouch nurse counselling and discussion regarding surgical alternatives, are also included. The last step of the checklist is discussion at a dedicated pouch-MDT. Discussion: A preoperative checklist may support clinicians with the selection of patients that are suitable for pouch surgery. It also serves as a useful tool to inform the discussion of cases at the MDT meeting.
RESUMEN
INTRODUCTION: Characterised by chronic inflammation of the gastrointestinal tract, inflammatory bowel disease (IBD) symptoms including diarrhoea, abdominal pain and fatigue can significantly impact patient's quality of life. Therapeutic developments in the last 20 years have revolutionised treatment. However, clinical trials and real-world data show primary non-response rates up to 40%. A significant challenge is an inability to predict which treatment will benefit individual patients.Current understanding of IBD pathogenesis implicates complex interactions between host genetics and the gut microbiome. Most cohorts studying the gut microbiota to date have been underpowered, examined single treatments and produced heterogeneous results. Lack of cross-treatment comparisons and well-powered independent replication cohorts hampers the ability to infer real-world utility of predictive signatures.IBD-RESPONSE will use multi-omic data to create a predictive tool for treatment response. Future patient benefit may include development of biomarker-based treatment stratification or manipulation of intestinal microbial targets. IBD-RESPONSE and downstream studies have the potential to improve quality of life, reduce patient risk and reduce expenditure on ineffective treatments. METHODS AND ANALYSIS: This prospective, multicentre, observational study will identify and validate a predictive model for response to advanced IBD therapies, incorporating gut microbiome, metabolome, single-cell transcriptome, human genome, dietary and clinical data. 1325 participants commencing advanced therapies will be recruited from ~40 UK sites. Data will be collected at baseline, week 14 and week 54. The primary outcome is week 14 clinical response. Secondary outcomes include clinical remission, loss of response in week 14 responders, corticosteroid-free response/remission, time to treatment escalation and change in patient-reported outcome measures. ETHICS AND DISSEMINATION: Ethical approval was obtained from the Wales Research Ethics Committee 5 (ref: 21/WA/0228). Recruitment is ongoing. Following study completion, results will be submitted for publication in peer-reviewed journals and presented at scientific meetings. Publications will be summarised at www.ibd-response.co.uk. TRIAL REGISTRATION NUMBER: ISRCTN96296121.

BACKGROUND: Persistent gastrointestinal symptoms are prevalent in adult patients with inflammatory bowel disease (IBD), even when endoscopic remission is reached. These symptoms can have profound negative effects on the quality of life of affected patients and can be difficult to treat. They may be caused by IBD-related complications or comorbid disorders, but they can also be explained by irritable bowel syndrome (IBS)-like symptoms. AIMS: To provide a practical step-by-step guide to diagnose and treat persistent gastrointestinal symptoms in patients with IBD in remission via a personalised approach. METHODS: We scrutinised relevant literature on causes, diagnostics and treatment of persistent gastrointestinal symptoms (abdominal pain or discomfort, bloating, abdominal distension, diarrhoea, constipation and faecal incontinence) in patients with IBD in remission. RESULTS: A graphical practical guide for several steps in diagnosing, identifying potential triggers and adequate treatment of persistent gastrointestinal symptoms in IBD in remission is provided based on supporting literature. The first part of this review focuses on the diagnostic and treatment approaches for potential IBD-related complications and comorbidities. The second part describes the approach to IBS-like symptoms in IBD in remission. CONCLUSIONS: Persistent gastrointestinal symptoms in IBD in remission can be traced back to potential pathophysiological mechanisms in individual patients and can be treated adequately. For both IBD-related complications and comorbidities and IBS-like symptoms in IBD in remission, pharmacological, dietary, lifestyle or psychological treatments can be effective. A systematic and personalised approach is required to reduce the burden for patients, healthcare systems, and society.

The first British Society of Gastroenterology (BSG) and Healthcare Infection Society (HIS)-endorsed faecal microbiota transplant (FMT) guidelines were published in 2018. Over the past 5 years, there has been considerable growth in the evidence base (including publication of outcomes from large national FMT registries), necessitating an updated critical review of the literature and a second edition of the BSG/HIS FMT guidelines. These have been produced in accordance with National Institute for Health and Care Excellence-accredited methodology, thus have particular relevance for UK-based clinicians, but are intended to be of pertinence internationally. This second edition of the guidelines have been divided into recommendations, good practice points and recommendations against certain practices. With respect to FMT for Clostridioides difficile infection (CDI), key focus areas centred around timing of administration, increasing clinical experience of encapsulated FMT preparations and optimising donor screening. The latter topic is of particular relevance given the COVID-19 pandemic, and cases of patient morbidity and mortality resulting from FMT-related pathogen transmission. The guidelines also considered emergent literature on the use of FMT in non-CDI settings (including both gastrointestinal and non-gastrointestinal indications), reviewing relevant randomised controlled trials. Recommendations are provided regarding special areas (including compassionate FMT use), and considerations regarding the evolving landscape of FMT and microbiome therapeutics.

BACKGROUND & AIMS: Colonoscopic surveillance is recommended in patients with colonic inflammatory bowel disease (IBD) given their increased risk of colorectal cancer (CRC). We aimed to develop and validate a dynamic prediction model for the occurrence of advanced colorectal neoplasia (aCRN, including high-grade dysplasia and CRC) in IBD. METHODS: We pooled data from 6 existing cohort studies from Canada, The Netherlands, the United Kingdom, and the United States. Patients with IBD and an indication for CRC surveillance were included if they underwent at least 1 follow-up procedure. Exclusion criteria included prior aCRN, prior colectomy, or an unclear indication for surveillance. Predictor variables were selected based on the literature. A dynamic prediction model was developed using a landmarking approach based on Cox proportional hazard modeling. Model performance was assessed with Harrell's concordance-statistic (discrimination) and by calibration curves. Generalizability across surveillance cohorts was evaluated by internal-external cross-validation. RESULTS: The surveillance cohorts comprised 3731 patients, enrolled and followed-up in the time period from 1973 to 2021, with a median follow-up period of 5.7 years (26,336 patient-years of follow-up evaluation); 146 individuals were diagnosed with aCRN. The model contained 8 predictors, with a cross-validation median concordance statistic of 0.74 and 0.75 for a 5- and 10-year prediction window, respectively. Calibration plots showed good calibration. Internal-external cross-validation results showed medium discrimination and reasonable to good calibration. CONCLUSIONS: The new prediction model showed good discrimination and calibration, however, generalizability results varied. Future research should focus on formal external validation and relate predicted aCRN risks to surveillance intervals before clinical application.

AIM: Quality of life (QoL) is a crucial and core outcome in assessing the effectiveness of treatments for cryptoglandular anal fistula. Despite its extensive impact, there is a lack of patient-centred, disease-specific QoL measurement instruments of adequate quality. The aim of this study is to develop a disease-specific measurement instrument that can accurately measure QoL for patients with cryptoglandular anal fistula. METHOD: Semi-structured qualitative patient interviews and a systematic review of current instruments were used to generate items for the draft instrument. This underwent successive rounds of cognitive interviews to refine its wording and structure. Individual item and overall scale content validity were determined by asking experts to rate the relevance of each item and those deemed irrelevant were removed. The final instrument then underwent psychometric testing and test-retest analysis to determine its sensitivity and stability. RESULTS: A total of 148 patients were involved in item generation, scale development and psychometric testing. A 22-item measurement instrument has been developed; it is scored on a scale of 0-100, where 0 indicates the worst QoL and 100 demonstrates perfect QoL. The scale demonstrates excellent internal consistency (Cronbach-α = 0.927), strong content and construct validity [correlation with Perianal Disease Activity Index = -0.713, Hospital Anxiety and Depression Anxiety (-0.659) and Depression (-0.673) subscales and Short Form-12 physical (0.609) and mental (0.589) component scales] and strong reliability and responsiveness. CONCLUSION: We have developed a cryptoglandular Anal Fistula Quality of Life scale (AF-QoL), a comprehensive, disease-specific patient reported outcome measure assessing QoL in patients with cryptoglandular anal fistula.

AIM: Patient understanding of disease can guide decision-making in the management of anal fistula. This prospective feasibility study aimed to assess the acceptability and methods of assessing the impact of viewing realistic models on patients with anal fistula. METHODS: New referrals to a tertiary clinic participated in this single-centre, parallel-group randomized controlled study. Baseline characteristics, Decisional Conflict Scale and understanding of disease were assessed pre-consultation. Participants were randomized to a standard consultation, where disease and treatment options were explained using magnetic resonance images and drawn diagrams, or a similar consultation supplemented with an appropriate generic three-dimensional (3D) printed model. Understanding of disease and proposed surgery, Decisional Conflict Scale and ratings of visual aids were assessed post-consultation, along with 3D model feedback. RESULTS: All 52 patients who were approached agreed to be randomized (25 standard, 27 3D consultation). Understanding of disease increased post-consultation in both groups. Post-consultation decisional conflict (0, no; 100, high decisional conflict) was low (median 27 post-standard vs. 24 post-3D consultation). Patients scored highly on measures assessing understanding of proposed surgery. 3D models were rated highly, with 96% of patients wanting to see them again in future consultations. CONCLUSIONS: Three-dimensional printed fistula models are a welcome addition to outpatient consultations with results suggesting that understanding of surgery is improved. A future trial should be powered to detect whether 3D models result in a significant improvement in understanding beyond traditional methods of explanation and explore the conditions in which models have their maximal utility. GOV REGISTRATION ID: This study was registered on ClinicalTrials.gov (ID: NCT04069728). Registered on 23 August 2019.

Due to their increased cancer risk, patients with longstanding inflammatory bowel disease are offered endoscopic surveillance with concomitant histopathologic assessments, aimed at identifying dysplasia as a precursor lesion of colitis-associated colorectal cancer. However, this strategy is beset with difficulties and limitations. Recently, a novel classification criterion for colitis-associated low-grade dysplasia has been proposed, and an association between nonconventional dysplasia and progression was reported, suggesting the possibility of histology-based stratification of patients with colitis-associated lesions. Here, a cohort of colitis-associated lesions was assessed by a panel of 6 experienced pathologists to test the applicability of the published classification criteria and try and validate the association between nonconventional dysplasia and progression. While confirming the presence of different morphologic patterns of colitis-associated dysplasia, the study demonstrated difficulties concerning diagnostic reproducibility between pathologists and was unable to validate the association of nonconventional dysplasia with cancer progression. Our study highlights the overall difficulty of using histologic assessment of precursor lesions for cancer risk prediction in inflammatory bowel disease patients and suggests the need for a different diagnostic strategy that can objectively identify high-risk phenotypes.

BACKGROUND AND AIMS: The Pharmacovigilance Risk Assessment Committee (PRAC) proposed measures to address severe side effects linked to Janus kinase inhibitors (JAKi) in immune-mediated inflammatory diseases (IMID). Use of these medications in individuals aged 65 and older, those at high cardiovascular risk, active or former long-term smokers, and those with increased cancer risk should be considered only if no alternatives exist. Caution is advised when administering JAKi to patients at risk of venous thromboembolism. We aim to implement recommendations from regulatory guidelines based on areas of uncertainty identified. METHODS: A two-round modified Research and Development/University of California Los Angeles appropriateness methodology study was conducted. A panel of 21 gastroenterologists, dermatologists and rheumatologists used a 9-point Likert scale to rate the appropriateness of administering a JAKi for each proposed clinical scenario. Scores for appropriateness were categorized as appropriate, uncertain, or inappropriate. Two rounds were performed, each with online surveys and a virtual meeting to enable discussion and rating of each best practice. RESULTS: Round 1 involved participants rating JAKi appropriateness and suggesting descriptors to reduce uncertainty. Survey results were discussed in a virtual meeting, identifying areas of disagreement. In round 2, participants rated their agreement with descriptors from round 1, and the level of uncertainty and disagreement reduced. Age flexibility is recommended in the absence of other risk factors. Active counseling on modifiable risks (e.g., overweight, mild hyperlipidemia and hypertension) and smoking cessation is advised. Uncertainty persists regarding cancer risk due to various factors. CONCLUSIONS: We outlined regulatory guidance without a personalized evaluation of the patient's risk profile might lead to uncertainty and become an arid technicality. Therefore, we identified gaps and implemented PRAC recommendations to help health professionals in clinical practice.
