Inter-Rater Disagreements in Applying the Montreal Classification for Crohn's Disease: The Five-Nations Survey Study.

Background: The Montreal classification has been widely used in Crohn's disease since 2005 to categorize patients by the age of onset (A), disease location (L), behavior (B), and upper gastrointestinal tract and perianal involvement. With evolving management paradigms in Crohn's disease, we aimed to assess the performance of gastroenterologists in applying the Montreal classification.

Methods: An online survey was conducted among participants at an international educational conference on inflammatory bowel diseases.

Clinical Approach to STRIDE-II in Real-Life Settings: Analysis and Practical Recommendations.

Background: We aimed to (1) analyze the applicability of the updated Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE-II) recommendations in real-world clinical practice, (2) identify barriers to their implementation, and (3) propose practical measures to overcome these obstacles.

Methods: This qualitative study was based on a survey, a literature review, and expert opinions. Nine inflammatory bowel disease (IBD) experts identified 7 areas likely to be controversial or potential implementation barriers in daily clinical practice: endoscopy, histology, ultrasound, quality of life, biomarkers, symptom control, and patient-reported outcomes (PROs).

[Experience of patients with immune-mediated inflammatory diseases seen in a multidisciplinary integrated care unit].

Objective: To describe the aspects with the greatest impact on the satisfaction of patients treated in a multidisciplinary unit specialising in immune-mediated inflammatory diseases (IMIDs) and to identify areas for improvement in the care model.

Methods: Cross-sectional descriptive study using a satisfaction survey structured in three blocks: sociodemographic variables, functional aspects of the unit and satisfaction with the professionals. Immediate satisfaction was measured on aspects related to the care received, the physical structure and the likelihood of recommending the unit.

Effectiveness and safety of a GLP-1 agonist in obese patients with inflammatory bowel disease.

Background: obesity affects many patients with inflammatory bowel disease (IBD). Glucagon-like peptide (GLP)-1 agonists are a promising therapy for obese patients. However, there is a lack of evidence of the use of these drugs in IBD patients.

Controversies in the management of anti-TNF therapy in patients with Crohn's disease: a Delphi consensus.

Background: Despite research, there are still controversial areas in the management of Crohn's disease (CD).

Objective: To establish practical recommendations on using anti-tumour necrosis factor (TNF) drugs in patients with moderate-to-severe CD.

Methods: Clinical controversies in the management of CD using anti-TNF therapies were identified.

Management of liver and gastrointestinal toxicity induced by immune checkpoint inhibitors: Position statement of the AEEH-AEG-SEPD-SEOM-GETECCU.

The development of the immune checkpoint inhibitors (ICI) is one of the most remarkable achievements in cancer therapy in recent years. However, their exponential use has led to an increase in immune-related adverse events (irAEs). Gastrointestinal and liver events encompass hepatitis, colitis and upper digestive tract symptoms accounting for the most common irAEs, with incidence rates varying from 2% to 40%, the latter in patients undergoing combined ICIs therapy.

Immune System and Brain/Intestinal Barrier Functions in Psychiatric Diseases: Is Sphingosine-1-Phosphate at the Helm?

Over the past few decades, extensive research has shed light on immune alterations and the significance of dysfunctional biological barriers in psychiatric disorders. The leaky gut phenomenon, intimately linked to the integrity of both brain and intestinal barriers, may play a crucial role in the origin of peripheral and central inflammation in these pathologies. Sphingosine-1-phosphate (S1P) is a bioactive lipid that regulates both the immune response and the permeability of biological barriers.

Benefits of Paediatric to Adult Transition Programme in Inflammatory Bowel Disease: The BUTTERFLY Study of GETECCU and SEGHNP.

(1) Background: Transition is a planned movement of paediatric patients to adult healthcare systems, and its implementation is not yet established in all inflammatory bowel disease (IBD) units. The aim of the study was to evaluate the impact of transition on IBD outcomes. (2) Methods: Multicentre, retrospective and observational study of IBD paediatric patients transferred to an adult IBD unit between 2017-2020.

Transmural or mucosal healing in Crohn´s disease. Which is the goal to be pursued?

In their original report of regional ileitis, Crohn, Ginzburg and Oppenheimer already described that inflammation involved not only the ileal mucosa: "the submucosal and, to a much lesser extent, the muscular layers of the bowel are the seat of marked inflammatory hyperplastic and exudative changes", they wrote 1. Ninety years later it is well established that the inflammatory process that characterizes Crohn´s disease (CD) involves all the layers of the intestinal wall; this fact is directly related with the development of progressive digestive tract damage related to disabling complications such as strictures, fistulae, perforation, and perianal or abdominal abscesses.

Real-World Evidence of Tofacinitib in Ulcerative Colitis: Short-Term and Long-Term Effectiveness and Safety.

Introduction: The objective of this study was to assess the durability, short-term and long-term effectiveness, and safety of tofacitinib in ulcerative colitis (UC) in clinical practice.

Methods: This is a retrospective multicenter study including patients with UC who had received the first tofacitinib dose at least 8 weeks before the inclusion. Clinical effectiveness was based on partial Mayo score.

deficiency and mucin depletion are implicated in intestinal barrier dysfunction as earlier event in the development of inflammation in interleukin-10-deficient mice.

Background: Dysbiosis and mucin depletion are related with intestinal barrier dysfunction and seems to be an early pathophysiological event in inflammatory bowel disease (IBD). The objective of this work is to study these parameters in the natural history of colitis in IL-10 deficient mice (IL-10).

Methods: Wild type (WT) and IL-10.

Single nucleotide polymorphisms in ADAM17, IL23R and SLCO1C1 genes protect against infliximab failure in adults with Crohn's disease.

Background: To predict primary failure of infliximab (IFX) therapy in Crohn's disease (CD) and to identify patients who maintain long-term effectiveness to IFX is currently not feasible. Some genetic variations are proposed as potential biomarkers.

Aim: We assessed a set of single nucleotide polymorphisms (SNPs) in genes related to the IFX mechanism of action and the presence of HLA-DQA1 * 05 allele on the primary response and long-term durability in CD patients.

Information and Communication Technologies in Patients With Immune-Mediated Inflammatory Diseases: Cross-sectional Survey.

Background: Information and communication technologies (ICTs) are changing the traditional health care model and redefining personalized health. ICTs offer effective communication and real-time monitoring of patients and provide additional data to support clinical decision-making, improve the quality of care, and contribute to the empowerment of patients. However, evidence on the use of ICTs and digital preferences of immune-mediated inflammatory disease (IMID) patients is scarce.

Design and implementation of a mobile app for the pharmacotherapeutic follow-up of patients diagnosed with immune-mediated inflammatory diseases: eMidCare.

Background: Pharmacotherapeutic management of immune-mediated inflammatory diseases (IMID) has become more complex due to the development of new treatments, such as biological therapies. Mobile health, especially apps, can provide IMID patients with greater autonomy and facilitate communication with healthcare professionals. Our objective was to design and implement an app for remote monitoring and communication with IMID patients.

Lentinula edodes extract increases goblet cell number and Muc2 expression in an intestinal inflammatory model of Trichinella spiralis infection.

AHCC® is a standardized extract of cultured mushroom (Lentinula edodes) mycelia with a wide variety of therapeutic effects including anti-inflammatory, antitumor and antiviral effects. Trichinellosis, a food-borne parasitic zoonosis is caused by the nematode Trichinella spp. Infection with Trichinella is characterized by the induction of a Th1-type response at the beginning of the intestinal phase, followed by a dominant Th2-type response which is essential for parasite expulsion.

Sphk2 deletion is involved in structural abnormalities and Th17 response but does not aggravate colon inflammation induced by sub-chronic stress.

The chronic inflammatory process that characterizes inflammatory bowel diseases (IBD) is mainly driven by T-cell response to microbial and environmental antigens. Psychological stress is a potential trigger of clinical flares of IBD, and sphingosine-1-phosphate (S1P) is involved in T-cell recruitment. Hence, stress impact and the absence of sphingosine kinase 2 (Sphk2), an enzyme of S1P metabolism, were evaluated in the colon of mice after sub-chronic stress exposure.

Impact of Biological Agents on Postsurgical Complications in Inflammatory Bowel Disease: A Multicentre Study of Geteccu.

Background: The impact of biologics on the risk of postoperative complications (PC) in inflammatory bowel disease (IBD) is still an ongoing debate. This lack of evidence is more relevant for ustekinumab and vedolizumab.

Aims: To evaluate the impact of biologics on the risk of PC.

Systematic review with meta-analysis: effect of inflammatory bowel disease therapy on lipid levels.

Background: Increase in lipid levels associated with the treatment of inflammatory bowel disease (IBD) has previously been reported. However, it is unknown if this effect is similar for all IBD drug classes.

Aim: To precisely assess the effect of different IBD drug classes on lipid profiles METHODS: We performed a systematic literature search of randomised controlled trials and observational cohort studies that assessed lipid levels before and after induction (≤10 weeks) and maintenance (>10 weeks) of IBD treatment.

ECCO Topical Review on Clinicopathological Spectrum and Differential Diagnosis of Inflammatory Bowel Disease.

Introduction: Many diseases can imitate inflammatory bowel disease [IBD] clinically and pathologically. This review outlines the differential diagnosis of IBD and discusses morphological pointers and ancillary techniques that assist with the distinction between IBD and its mimics.

Methods: European Crohn's and Colitis Organisation [ECCO] Topical Reviews are the result of an expert consensus.

Histological inflammatory activity can predict endoscopic relapse in patients with ulcerative colitis who have achieved mucosal healing.

Background Aims: Current therapeutic goals in ulcerative colitis (UC) include clinical and endoscopic remission, named mucosal healing (MH). Despite MH, a proportion of patients suffer a clinical relapse, which has been related to histological inflammation. We aimed to identify which histopathological features or histopathological index cut-off was associated with endoscopic relapse (ER) in UC patients with MH.
