RESUMEN
This article is the second in a series of two publications on the European Crohn's and Colitis Organisation [ECCO] evidence-based consensus on the management of Crohn's disease. The first article covers medical management; the present article addresses surgical management, including preoperative aspects and drug management before surgery. It also provides technical advice for a variety of common clinical situations. Both articles together represent the evidence-based recommendations of the ECCO for Crohn's disease and an update of prior ECCO guidelines.
RESUMEN
The genetic background of inflammatory bowel disease, both Crohn's disease and ulcerative colitis, has been known for more than 2 decades. In the last 20 years, genome-wide association studies have dramatically increased our knowledge on the genetics of inflammatory bowel disease with more than 200 risk genes having been identified. Paralleling this increasing knowledge, the armamentarium of inflammatory bowel disease medications has been growing constantly. With more available therapeutic options, treatment decisions become more complex, with still many patients experiencing a debilitating disease course and a loss of response to treatment over time. With a better understanding of the disease, more effective personalized treatment strategies are looming on the horizon. Genotyping has long been considered a strategy for treatment decisions, such as the detection of thiopurine S-methyltransferase and nudix hydrolase 15 polymorphisms before the initiation of azathioprine. However, although many risk genes have been identified in inflammatory bowel disease, a substantial impact of genetic risk assessment on therapeutic strategies and disease outcome is still missing. In this review, we discuss the genetic background of inflammatory bowel disease, with a particular focus on the latest advances in the field and their potential impact on management decisions.

INTRODUCTION: It is still unknown whether eosinophilic esophagitis (EoE) patients with localized disease are different from those with extended disease. METHODS: We evaluated prospectively included patients in the Swiss EoE cohort. Data on all patients with active disease at baseline, no concomitant gastroesophageal reflux disease, no strictures at baseline, and at least one follow-up visit were analyzed. We compared patients with histologically localized proximal versus distal versus extended (=proximal and distal) disease with regard to patient, disease characteristics, disease presentation, and development of complications. RESULTS: We included 124 patients with a median of 2.5 years of follow-up (73.4% males, median age 35.0 years). Ten patients had proximal (8.1%), 46 patients had distal (37.1%), and 68 patients had extended disease (54.8%). Patients with proximal disease were significantly more often females (80%) compared with patients with distal (26.1%, p = 0.002) or extended disease (19.1%, p < 0.001) and reported less severe symptoms (VAS 0 vs. VAS 1, p = 0.001). Endoscopic and histological disease was less pronounced in the proximal esophagus of proximal EoE compared to extended disease (EREFS 1.0 vs. 3.0, p = 0.001; 27.0 eos/hpf vs. 52.5 eos/hpf, p = 0.008). Patients with proximal disease were less likely to undergo dilation compared to patients with distal disease in the follow-up (3.3% vs. 23.3%, p = 0.010). In a multivariate Cox regression model, proximal eosinophilia was less likely to be associated with treatment failure compared to distal eosinophilia. CONCLUSION: Although isolated proximal EoE is infrequent, it is associated with less severe disease and better disease outcome. Proximal disease appears to present a unique EoE phenotype.

INTRODUCTION: Chronic inflammatory bowel diseases (IBD) are inflammatory gastrointestinal disorders that are not limited to the gastrointestinal tract. Many different organ systems may be involved, which makes IBD a systemic disease. The most common extraintestinal manifestations (EIM) include musculoskeletal, ophthalmological, dermatological, and hepato-biliary disorders. EIM considerably contribute to the morbidity of patients with IBD, and they limit quality of life of affected patients. Due to the diversity of the organ systems involved, care should be provided by an interdisciplinary team. Early detection of EIM allows targeted therapy and reduces overall morbidity. Of importance is the fact that EIM can occur in up to 25% of all IBD patients before the onset of the first Crohn's episode or ulcerative colitis. Therefore, all doctors, especially dermatologists, ophthalmologists and rheumatologists should be aware of this possible association between EIM and the simultaneous occurrence of intestinal symptoms.

BACKGROUND: Vedolizumab (VDZ), a gut-selective anti-lymphocyte trafficking integrin antibody, is effective in treating patients with moderately to severely active Crohn's disease (CD). In this study, we examined the real-world effectiveness and safety of induction therapy using VDZ alone or in combination with budesonide (VDZ + BUD) among patients with CD in Belgium, Israel, and Switzerland. METHODS: This retrospective chart review analysis included adult patients with moderately to severely active CD who started induction treatment with VDZ or VDZ + BUD (January 2015 through January 2019). The primary objective of this study was to assess the effectiveness in terms of clinical remission of VDZ alone or VDZ + BUD using patient-reported outcomes (PRO) of abdominal pain (AP) and/or loose stool frequency (LSF) (PRO-2) at weeks 0, 2, 6, 10, and 14. Regression models were used to assess differences and associations between the treatment groups. RESULTS: Overall, 123 patients were included (VDZ, n = 73; VDZ + BUD, n = 50). Clinical remission rates at week 14 were 71.4% (50/70) and 68.0% (34/50) with VDZ and VDZ + BUD, respectively. Mean percentage change in AP and LSF from baseline to week 14 was comparable between the groups. Median (95% confidence interval [CI]) time to clinical remission was 91 [70.0-98.0] and 95 [70.0-98.0] days, respectively. One patient in each group discontinued VDZ and 68.0% of patients in the VDZ + BUD group discontinued BUD before week 14. The rates of overall adverse events were similar between the groups (VDZ, 23.3%; VDZ + BUD, 26.0%). CONCLUSIONS: In this retrospective study, VDZ alone and VDZ + BUD showed similar high remission rates in patients with moderately to severely active CD. Prospective randomized studies are needed to conclude on the role of combining VDZ with BUD. TRIAL REGISTRATION: Not applicable.

Introduction: Patient adherence is a major challenge for the successful management of any chronic disease, and ulcerative colitis (UC) is no exception. Patient adherence is closely related to patient preference of medication and formulation used. Aim: The aim of this study was to investigate patient and physician perspectives around UC treatment preference. Methods: This study was conducted in France, Germany, Spain, and the UK. Physicians and UK inflammatory bowel disease (IBD) nurses answered an online questionnaire. In addition, adult mild-to-moderate UC patients, treated with oral mesalazine, were invited to answer a 30-min online survey which included a conjoint exercise. Results: 400 patients, 160 physicians, and 20 IBD nurses participated in the survey. 68% of patients were taking tablets and 32% granules. Physicians stated that from their perspective patients are more adherent to tablets than granules (76% vs. 24%), patients tended to have better relief of symptoms with tablets (69% vs. 31%), and patients found tablets to be the most convenient formulation (61% vs. 39%). From the patients' perspective, when questioned which formulation they prefer, 58% answered tablets, 37% granules, and 5% none of these. When patients were asked about some negative attributes of tablets, the highest agreement was for "I would like to take fewer each day" (6.1/10) and "I wish I could take fewer at a time" (5.4/10). Conclusions: The majority of UC patients in this survey prefer the tablet formulation. A high strength tablet overcoming the high pill burden could be a good solution to address patient expectations.
RESUMEN
INTRODUCTION: Faecal microbiota transplantation (FMT) is an established therapy for recurrent C. difficile infection, and recent studies have reported encouraging results of FMT in patients with ulcerative colitis. Few international consensus guidelines exist for this therapy, and thus FMT policies and practices differ among European countries. As of 2019, stool transplants are considered a non-standardised medicinal product in Switzerland, and a standardised production process requires authorisation by the Swiss Agency for Therapeutic Products. This authorisation leads to prolonged administrative procedures and increasing costs, which reduces treatment accessibility. In particular, patients with ulcerative colitis in Switzerland can only benefit from FMT off-label, even though it is a valid therapeutic option. Therefore, this study summarised the available data on FMT and established a framework for the standardised use of FMT. METHODS: A panel of Swiss gastroenterologists with a special interest in inflammatory bowel disease was established to identify the current key issues of FMT. After a comprehensive review of the literature, statements were formulated about FMT indications, donor screening, stool transplant preparation and administration, and safety aspects. The panel then voted on the statements following the Delphi process; the statements were reformulated and revoted until a consensus was reached. The manuscript was then reviewed by an infectiologist (the head of Lausanne's FMT centre). RESULTS: The established statements are summarised in the supplementary tables in the appendix to this paper. The working group hopes these will help standardise FMT practice in Switzerland and contribute to making faecal microbiota transplantation a safe and accessible treatment for patients with recurrent C. difficile infections and selected patients with ulcerative colitis, as well as other indications in the future.

Background: While the detrimental impact of negative emotions on the clinical course of inflammatory bowel disease (IBD) and quality of life has been extensively investigated, evidence for a potential impact of positive emotions is scarce. Objectives: We aim to analyse contributing factors of positive affect and their predictive value for disease course in IBD patients. Design: In this retrospective cohort study, epidemiological, psychosocial and IBD disease characteristics of Swiss IBD cohort study patients were analysed longitudinally. Methods: Epidemiological, psychosocial and disease characteristics were extracted from the database of the Swiss IBD cohort study. Participants' positive emotions were assessed cross-sectionally with the seven-item Marburg questionnaire (range 1-6) addressing positive affect in different aspects of daily life. Predictors of positive emotions were identified by linear regression. The quantitative longitudinal impact of positive emotions on the further disease course was analysed using a multivariable Cox proportional hazards model. Results: Among 702 IBD patients, those reporting more positive emotions were found to have significantly less intense medical treatment, less pain and fewer depressive symptoms (p < 0.05). A higher percentage of variability in positive emotions was explained by pain (36%) and depressive symptoms (13%) than by epidemiological characteristics (0.3%), or characteristics of IBD and its treatment (2.4%). Patients with higher levels of positive emotions (score > 3.5) experienced longer flare-free survival, also after adjusting for confounders (adjusted hazard ratio: 0.39, p < 0.05). Conclusions: The absence of pain and depressive symptoms were the strongest drivers for high positive affect. Higher scores of positive affect were associated with longer disease-free survival in IBD patients.
RESUMEN
Spondyloarthritis (SpA) encompasses a heterogeneous group of chronic inflammatory diseases that can affect both axial and peripheral joints, tendons and entheses. Among the extra-articular manifestations, inflammatory bowel disease (IBD) is associated with considerable morbidity and effects on quality of life. In everyday clinical practice, treatment of these conditions requires a close collaboration between gastroenterologists and rheumatologists to enable early detection of joint and intestinal manifestations during follow-up and to choose the most effective therapeutic regimen, implementing precision medicine for each patient's subtype of SpA and IBD. The biggest issue in this field is the dearth of drugs that are approved for both diseases, as only TNF inhibitors are currently approved for the treatment of full-spectrum SpA-IBD. Janus tyrosine kinase inhibitors are among the most promising drugs for the treatment of peripheral and axial SpA, as well as for intestinal manifestations. Other therapies such as inhibitors of IL-23 and IL-17, phosphodiesterase 4 inhibitor, α4ß7 integrin blockers and faecal microbiota transplantation seem to only be able to control some disease domains, or require further studies. Given the growing interest in the development of novel drugs to treat both conditions, it is important to understand the current state of the art and the unmet needs in the management of SpA-IBD.

BACKGROUND: Patients with inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, may develop extraintestinal manifestations (EIMs). The EMOTIVE study aimed to analyze the effect of vedolizumab on EIMs in a real-world cohort of patients with IBD. METHODS: This multicenter, descriptive, retrospective study was conducted in Belgium, Denmark, Israel, the Netherlands, and Switzerland in adults with moderately to severely active IBD and concurrent active EIMs at vedolizumab initiation (index date), with a ≥6-month follow-up after the index date. The primary endpoint was resolution of all EIMs within 6 months of vedolizumab initiation. RESULTS: In 99 eligible patients, the most frequent EIMs were arthralgia (69.7%), peripheral spondyloarthritis (21.2%), and axial spondyloarthritis (10.1%). Within 6 and 12 months of vedolizumab initiation, 19.2% and 25.3% of patients reported resolution of all EIMs, while 36.5% and 49.5% of all EIMs were reported to be improved (combination of resolution and partial response), respectively. Vedolizumab treatment persistence at 12 months was 82.8%. Adverse events were reported in 18.2% of patients, with the most frequent being arthralgia (4.0%). CONCLUSIONS: This real-world study showed resolution of all EIMs in up to one-fourth of patients with IBD and improvement in up to half of EIMs within 12 months of vedolizumab treatment. Overall, vedolizumab was effective on EIMs in patients with IBD and showed a good safety profile.

BACKGROUND: Patients with inflammatory bowel disease are at increased risk of colorectal and extra-intestinal cancer. However, the overall cancer risk in patients with Crohn's disease (CD) with perianal fistulas (PF) (CPF) and those with CD without PF (non-PF CD) is unclear. OBJECTIVE: To describe the prevalence and incidence of cancer in patients with CPF and non-PF CD, and to estimate incidence rate ratio (IRR) of cancer between CPF and non-PF CD groups. METHODS: A retrospective cohort study was conducted using the German InGef (Institute for Applied Health Research Berlin) research database. Patients with a CD record and PF from 1 January 2013 to 31 December 2014 were identified and followed up from 1 January 2015 until the first occurrence of cancer, end of health insurance contributing data, death, or end of study period (31 December 2020). Prevalence of any type of cancer including patients with CD diagnosed with cancer in the selection period and incidence of cancer excluding patients with CD diagnosed with cancer in the selection period were calculated. RESULTS: In total, 10,208 patients with CD were identified. Of 824 patients with CPF (8.1%), 67 had had a malignancy (6-year period crude malignancy prevalence 8.13% [95% confidence interval (CI) 6.36%-10.21%]), which was lower than patients with non-PF CD (19.8% [95% CI 19%-20.6%]). Incidence (per 100,000 person-years) in patients with CPF was 1184 (95% CI 879-1561) and in non-PF CD was 2365 (95% CI 2219-2519). There was no significant difference in the adjusted IRR of cancer for the CPF group compared with the non-PF CD group (0.83 [95% CI 0.62-1.10]; p = 0.219). CONCLUSION: There was no significant difference in the incidence of any cancer in patients with CPF compared with non-PF CD. However, patients with CPF had a higher numerical risk of cancer than the general German population.

BACKGROUND: The effectiveness of anti-TNF or ustekinumab (UST) as a second-line biologic after vedolizumab (VDZ) failure has not yet been described. AIMS AND METHODS: In this retrospective multicenter cohort study, We aim to investigate the effectiveness of anti-TNF and UST as second-line therapy in patients with Crohn's disease (CD) who failed VDZ as a first-line treatment. The primary outcome was clinical response at week 16-22. Secondary outcomes included the rates of clinical remission, steroid-free clinical remission, CRP normalization, and adverse events. RESULTS: Fifty-nine patients who failed on VDZ as a first-line treatment for CD were included; 52.8% patients received anti-TNF and 47.2% UST as a second-line therapy. In initial period (Week 16-22), the clinical response and remission rate was similar between both groups: 61.2% vs. 68%, p = 0.8 and 48.3% vs. 56%, p = 0.8 on anti-TNF and UST therapy, respectively. Furthermore, in the maintenance period the rate was similar: 75% vs. 82.3%, p = 0.8 and 62.5% vs. 70.5%, p = 0.8, respectively. Of the patients, 12 out of the 59 stopped the therapy, without a significant difference between the two groups (p = 0.6). CONCLUSION: Second-line biological therapy after VDZ failure therapy was effective in >60% of the patients with CD. No differences in effectiveness were detected between the use of anti-TNF and UST as a second line.
RESUMEN
Frequent Gastro-Intestinal Disorders: Management of Functional Dyspepsia and Irritable Bowel Syndrome in Clinical Practice Abstract: Functional dyspepsia (FD) and irritable bowel syndrome (IBS), two common gastrointestinal entities with overlapping symptoms, should be diagnosed according to Rome IV criteria. This includes one or more of the following symptoms: in FD, postprandial fullness, early satiation, epigastric pain or burning; in IBS, recurrent abdominal pain associated with defecation, change in frequency of stool or form of stool. To exclude structural diseases, attention should be paid to alarm symptoms. As far as treatment is concerned, a stepwise scheme proves to be effective for both diseases. Step 1: doctor-patient discussion with explanation of diagnosis and prognosis as well as clarification of therapy goals; lifestyle adaptations; use of phytotherapeutics; step 2: symptom-oriented medication: for FD, PPIs or prokinetics; for IBS, antispasmodics, secretagogues, laxatives, bile acid sequestrants, antidiarrheals, antibiotics, probiotics; step 3: visceral analgesics (antidepressants).

BACKGROUND AND AIM: Pneumocystis jirovecii pneumonia [PJP] is a very rare, potentially life-threatening pulmonary fungal infection that occurs in immunocompromised individuals including patients with inflammatory bowel disease [IBD]. Our aim was to describe immunosuppressive treatment exposure as well as the outcome in IBD patients with PJP. METHODS: PJP cases were retrospectively collected through the COllaborative Network For Exceptionally Rare case reports of the European Crohn's and Colitis Organisation. Clinical data were provided through a case report form. RESULTS: In all, 18 PJP episodes were reported in 17 IBD patients [10 ulcerative colitis and seven Crohn's disease]. The median age at PJP diagnosis was 55 years (interquartile range [IQR], 40-68 years]. Two PJP [11.1%] occurred in patients on triple immunosuppression, 10 patients [55.6%] had double immunosuppressive treatment, four patients [22.2%] had monotherapy and two PJP occurred in absence of immunosuppressive treatment [one in a human immunodeficiency virus patient and one in a patient with a history of autologous stem cell transplantation]. Immunosuppressive therapies included steroids [nâ =â 12], thiopurines [nâ =â 10], infliximab [nâ =â 4], ciclosporin [nâ =â 2], methotrexate [nâ =â 1], and tacrolimus [nâ =â 1]. None of the patients diagnosed with PJP had received prophylaxis. All patients were treated by trimethoprim/sulphamethoxazole or atovaquone and an intensive care unit [ICU] stay was required in seven cases. Two patients [aged 71 and 32 years] died, and one patient had a recurrent episode 16 months after initial treatment. Evolution was favourable for the others. CONCLUSION: This case series reporting potentially fatal PJP highlights the need for adjusted prophylactic therapy in patients with IBD on immunosuppressive therapy.

OBJECTIVES OF THE STUDY: There is little guidance regarding the impact of alcohol and cannabis on the clinical course of inflammatory bowel disease. The aim of this study was to assess the prevalence, sociodemographic characteristics and impact of alcohol and cannabis use on the clinical course of the disease. METHODS: We performed an analysis of prospectively collected data within the Swiss Inflammatory Bowel Disease Cohort Study with yearly follow-ups and substance-specific questionnaires. We analyzed the prevalence of use, the profile of users at risk for addiction and the impact of alcohol and cannabis on the course of the disease. RESULTS: We collected data of 2828 patients included between 2006 and 2018 and analyzed it according to their completion of specific surveys on alcohol and cannabis use. The prevalence of patient-reported active use was 41.3% for alcohol and 6% for cannabis. Heavy drinkers were over-represented among retired, married smokers receiving mostly aminosalicylates and less immunosuppression. In ulcerative colitis patients, low-to-moderate drinking was associated with less extensive disease. Cannabis users were often students with ileal Crohn's disease. CONCLUSION: A significant proportion of patients with inflammatory bowel disease consume alcohol or cannabis. Heavy alcohol consumption is most likely in male smokers >50 years, whereas young men with ileal disease rather use cannabis.

Introduction: Given the lack of data, we aimed to assess the impact of the length of diagnostic delay on the natural history of ulcerative colitis (UC) in pediatric (diagnosed <18 years) and adult patients (diagnosed ≥18 years). Methods: Data from the Swiss Inflammatory Bowel Disease Cohort Study were analyzed. Diagnostic delay was defined as the interval between the first appearance of UC-related symptoms until diagnosis. Logistic regression modeling evaluated the appearance of the following complications in the long term according to the length of diagnostic delay: colonic dysplasia, colorectal cancer, UC-related hospitalization, colectomy, and extraintestinal manifestations (EIMs). Results: A total of 184 pediatric and 846 adult patients were included. The median diagnostic delay was 4 [IQR 2-7.5] months for the pediatric-onset group and 3 [IQR 2-10] months for the adult-onset group (p = 0.873). In both, pediatric- and adult-onset groups, the length of diagnostic delay at UC diagnosis was not associated with colectomy, UC-related hospitalization, colon dysplasia, and colorectal cancer. EIMs were significantly more prevalent at UC diagnosis in the adult-onset group with long diagnostic delay than in the adult-onset group with short diagnostic delay (p = 0.022). In the long term, the length of diagnostic delay was associated in the adult-onset group with colorectal dysplasia (p = 0.023), EIMs (p < 0.001), and more specifically arthritis/arthralgias (p < 0.001) and ankylosing spondylitis/sacroiliitis (p < 0.001). In the pediatric-onset UC group, the length of diagnostic delay in the long term was associated with arthritis/arthralgias (p = 0.017); however, it was not predictive for colectomy and UC-related hospitalization. Conclusions: As colorectal cancer and EIMs are associated with considerable morbidity and costs, every effort should be made to reduce diagnostic delay in UC patients.
