Contrary to everyone’s ardent expectations and hopes, this year’s ECCO Congress was once again held virtually. While the experiences from 2021 had taught the H-ECCO Committee how to prepare for this and what to expect, we were so happy to be supported again by an excellent ECCO Office team.
I hope you all enjoyed the ECCO Congress and got a lot out of sailing the seas of IBD! Although we were forced to hold the Congress digitally, there was a huge amount of great content – not least the contributions from Y-ECCO Members. Fourteen oral presentations were selected to be presented by Y-ECCO Members and a total of 20 Y-ECCO Members were awarded prizes. This demonstrates the great driving force of Y-ECCO within ECCO and paves the way for the next generation of IBD experts. Our annual Basic Science Workshop, which has been going since 2015, was again a great success. More information on what the 67 workshop participants were treated to can be read in the separate report by Y-ECCO Committee Member Gianluca Pellino.
For another year, unexpectedly, the Y-ECCO Basic Science Workshop had to be an online-only event, as the uncertainties related to the status of the pandemic caused the ECCO Congress 2022 to be changed into a virtual event. However, the workshop participants showed clearly that this did not affect their enthusiasm.
Crohn’s Disease (CD) is a chronic gastrointestinal inflammatory condition  that commonly causes strictures, with more than 50% of patients developing at least one stricture in the first decade after diagnosis . Management options include biologics, endoscopic dilatation and surgery. Dilatation requires that the stricture be endoscopically accessible and medical therapy has limited benefit in fibrostenosing disease; therefore, surgery often remains the initial treatment of choice . MRI and ultrasound can provide detailed assessment but cannot always definitively quantify active inflammation [4, 5].
This open label, randomised control trial was carried out at a specialist IBD unit in Australia with the aim of establishing whether medical therapy is an effective treatment of stricturing CD and, if so, whether intensive medical therapy is more effective than standard therapy. The primary end point was an improvement in the 14-day obstructive symptom score by one or more points compared to baseline at 12 months. Secondary outcomes included: improvement in the Crohn’s Disease Activity Index (CDAI), C-reactive protein (CRP), faecal calprotectin (FCP), stricture morphology on MRI, small bowel ultrasound (SBUS) or endoscopy, and correlation of serum adalimumab concentration with any improvement.
Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is often the preferred surgical intervention for patients with medically refractory Ulcerative Colitis . A significant proportion of patients with IPAA develop pouch-related symptoms characterised by increased pouch emptying, urgency, bloody exudates and cramps. Such symptoms can occur secondary to inflammatory disorders, including idiopathic pouchitis, which affects up to 50% of patients, or other conditions such as pre-pouch ileitis . Symptoms can also be due to non-inflammatory disorders, with irritable-pouch dysfunction accounting for more than a third of symptomatic patients.
The most commonly accepted disease activity index is the Pouchitis Disease Activity Index (PDAI), which combines symptoms, endoscopy findings and histology. A total PDAI 7 is considered diagnostic for pouchitis but is not specific .
The gold standard investigation is pouchoscopy, which allows endoscopic and histological assessment of the pouch, pre-pouch ileum and cuff . However, it is an invasive and often uncomfortable procedure for patients. In some cases the alternative strategy of empirical antibiotic therapy for every symptomatic episode is adopted, but this comes with the risks associated with unnecessary antibiotic use.
In this cross-sectional study, Ardalan et al. sought to assess the role of non-invasive gastrointestinal ultrasound (GIUS) and faecal calprotectin (FCP) testing in the investigation of pouchitis.
The management of Inflammatory Bowel Disease (IBD) has evolved significantly over the last two decades [1, 2], as the development of biologic therapy has increased dramatically the rates of induction and prolonged maintenance of remission in patients with IBD. Infliximab (an anti-tumour necrosis factor) was the first biologic therapy to be approved for the treatment of IBD  and remains the biologic therapy with which clinicians have the most clinical experience .
Due to comorbidities, patients are frequently on other medications in addition to infliximab. How these other concomitant medications influence the response to infliximab therapy is largely unexplored.
Proton pump inhibitors (PPIs) are the first-line treatment for many digestive disorders such as gastro-oesophageal reflux disease (GORD), peptic ulcers, eosinophilic oesophagitis and dyspepsia . PPIs are one of the most used family of medications in the United States, with more than 50 million prescriptions filled every year .
A few retrospective trials have attempted to investigate the impact of concomitant PPI therapy on response to infliximab in patients with IBD; however, these studies have suffered from the presence of many confounders, such as the lack of data on smoking status or the increased risk for gastroenteritis and C. difficile infection amongst patients treated with PPIs.
To increase the power to detect differential effects of PPI treatment on patients treated with infliximab in randomised trials and to allow adjustment for confounding factors, the investigators performed a patient-level meta-analysis of IBD randomised controlled clinical trials from the Yale Open Data Access (YODA) Framework.
Paulo Kotze is Adjunct Senior Professor of Surgery at the Colorectal Surgery Unit at Cajuru University Hospital in Curitiba, Brazil. Working as a colorectal surgeon, he manages IBD with both the scalpel and medical therapies. He has been a key figure in ECCO for many years, having been a committee member of both S-ECCO and, more recently, EduCom. In the absence of the ECCO Congress, I spoke with him over Zoom about global ECCO, being an iconoclastic surgeon and his past as a bassist in the Brazilian punk band the Pinheads.
The BIOCYCLE project has now been ongoing for 7 years. This project, funded by the European Commission under the Horizon 2020 programme, aims to explore different aspects of the question of treatment de-escalation in moderate-severe Crohn’s Disease requiring a combination therapy with anti-TNF and antimetabolites to control the disease. An unsolved question is whether it is possible to de-escalate therapy once the disease has been stabilised. This question is important for several reasons, including safety, tolerance, quality of life and costs, to name the most prominent. BIOCYCLE includes a randomised, three-arm, controlled clinical trial on 210 patients in seven European countries, several patients’ and health care providers’ surveys in Europe and the United States, a biomarker research programme and pharmaco-economic analysis. ECCO is mainly involved in the monitoring of the project (through IBDIM) and is the work package leader for dissemination of the results. BIOCYCLE is a 7.5-year-long project and was launched in April 2015.
Welcome to our Spring issue of ECCO News and our first publication of ECCO News for 2022. We hope that you've been keeping well, have enjoyed the ECCO Congress and are looking forward to our new installment of the editorial officers' interview corner.
It gives me great pleasure to introduce you to Professor Edouard Louis, the bicycle and BIOCYCLE king. Prof Louis is the head of the department and a professor of Gastroenterology at University Hospital CHU of Liege, Belgium. He is well-known to us all with his previous ECCO Committee positions and his current role as an associate editor for JCC. One of the most exciting topics over the last few years was the BIOCYCLE project, which Prof Louis elaborates on during this interview. The interview format is the second of its kind in the fact that it's recorded for you to be able to watch or listen to at your leisure. We hope you enjoy joining us on this "Bi (O)cycle" ride.

Diet is a significant factor in the development of Inflammatory Bowel Disease (IBD) and management of the condition. The Crohn’s Disease Exclusion Diet (CDED) has been shown to be effective in achieving remission, but could it be used more widely?
Increased fibre intake is a key element of CDED, but does it always have a beneficial impact? Recent studies have investigated how CDED impacts the microbiota and whether food additives could contribute to the development of IBD.
