The Educational Programme at the ECCO Congress in 2024 will once again feature two workshops focused on imaging Inflammatory Bowel Diseases (IBD). These workshops, held in collaboration with the European Society of Gastrointestinal and Abdominal Radiology (ESGAR) and the International Bowel Ultrasound (IBUS) group, aim to educate medical professionals about the latest imaging technologies and their application in precise diagnosis and therapeutic management of IBD patients.

The first workshop will cover basic endoscopy, ultrasound and MRI, while the second will delve into advancements in intestinal ultrasound. These workshops are made possible through extensive cooperation between ECCO and experienced gastroenterologists and radiologists in intestinal imaging.

The 22nd ECCO IBD Intensive Course for Trainees, Stockholm 2024

The IBD Intensive Course for Trainees will take place over one day on Wednesday, February 21, 2024, prior to the official start of the ECCO Congress. This ECCO Educational Initiative has a rich history, dating back to its conception in 2003, even before the launch of the ECCO Congress.

The fundamentals of IBD education begin during gastroenterology fellowship training. However, IBD medical education is often fragmented. The IBD Intensive Course for Trainees aims to provide advanced fellows in gastroenterology with a comprehensive understanding of IBD from a multidisciplinary perspective. In addition, the course presents a valuable opportunity for young clinicians to connect with colleagues from various countries around the globe, allowing them to explore different medical standards and establish a network for potential future collaborations. Participation in the programme is by invitation, with students nominated by ECCO National Representatives.

Introduction

The incidence and prevalence of Inflammatory Bowel Disease (IBD) are progressively increasing worldwide, particularly in developing countries. Despite increasing awareness of IBD and improvements in biomarkers and diagnostic techniques, a significant diagnostic delay is still frequently observed. This is highly relevant as diagnostic delay prevents application of medical treatment during very early disease stages and the implementation of certain disease intervention strategies. Diagnostic delay is consequently still limiting our potential to alter the natural history of the disease, as has recently been shown by UK colleagues. In a systematic review and meta-analysis, it was demonstrated that individuals with Crohn’s Disease (CD) in the higher quartiles of diagnostic delay (median 24 months) were more likely to have stricturing or penetrating disease and were also more likely to undergo intestinal surgery, while in patients with Ulcerative Colitis (UC) such a delay was associated with increased probability of colectomy [1]. Hence, reducing diagnostic delay should be a priority if we are aiming to apply effective disease intervention strategies.

In the fast-paced world of medical research and drug development, efficient data management and transparent communication are critical factors for success. To address these challenges, the European Medicines Agency (EMA) has launched a new Clinical Trials Information System (CTIS) that went live on January 31, 2022 [1, 2]. The CTIS is the backbone of the Clinical Trials Regulation, which will harmonise the assessment and supervision of clinical trials in the European Union. There is a transition period until January 31, 2025. Any ongoing trial that has been approved under the Clinical Trial Directive will then fall under the Clinical Trials Regulation [1–3].

After repeated postponements due to travel restrictions to Japan, I was able to carry out enteroscopy training at the Tokyo Medical and Dental University (TMDU) Hospital between September and October 2022.

Induction of circadian microbial function in chronic intestinal inflammation

Background & aim of research

Impaired clock gene expression has been observed in biopsies from patients with Inflammatory Bowel Disease (IBD). Disruption of circadian rhythms, which occurs in shift workers, has been linked to an increased risk of gastrointestinal diseases, including IBD. The intestinal clock balances gastrointestinal homeostasis by regulating the microbiome. We aimed to characterise intestinal immune functions in mice lacking the intestinal clock and in IBD-relevant mouse models under different feeding conditions in order to assess the functional impact of the intestinal clock in the development of gastrointestinal inflammation.

Investigating the genetics of IBD multiplex families

Background & aim of research

This research aimed to investigate the genetic architecture of Inflammatory Bowel Disease (IBD) multiplex families (including at least three affected first-degree relatives), and to identify the underlying genetic factors that contribute to the familial aggregation of IBD.

Background & aim of research

Primary Sclerosing Cholangitis (PSC) is a progressive choleostatic disease and up to 80% of patients also have Ulcerative Colitis (PSC-UC). This presents a clinical challenge owing to the diagnostic difficulty and the increased risk for development of cancer. The aim of this study was to identify the transcriptomic and epigenetic alterations regulating the phenotype of this disease.

The role of autophagy in limiting IBD-associated AIEC-induced intestinal inflammation

Shai Bel © Shai Bel

Background & aim of research

While the aetiology underlying the development of Inflammatory Bowel Diseases (IBD) is unclear, evidence points to an interaction between host genetics, such as mutations in autophagy genes, and environmental factors, such as bacterial infections. Multiple studies have identified an adherent-invasive Escherichia coli pathotype (AIEC) only in patients with IBD. It is thought that AIEC exploits the intestinal inflammation in patients with IBD to attach to intestinal epithelial cells, intensifying the pre-existing inflammation. Studies in vitro have shown that functional autophagy is crucial to eliminate AIEC infection. Here, we aimed to identify how autophagy protects the host from AIEC-associated pathologies in vivo.

For two years, a group of 25 IBD specialists, including gastroenterologists, surgeons and scientists, have been working to build a research framework for postoperative recurrence (POR) in patients with Crohn’s Disease. Even though more biological therapies are now available, ileocaecal resection is still a frequent event and POR management remains a challenge for both patients and IBD specialists.
