Dear ECCO Friends,

It was not only wonderful to meet all members of the ECCO family in Copenhagen, but also to have a personal exchange again. Without a doubt, all the committees and workshops have also benefited from this "traditional – in person" format, as we will see in a moment from the summary of the many activities of the Congress in this issue. First of all, however, I am delighted to have taken over the presidency from Laurent Peyrin-Biroulet and to be able to lead, strengthen and develop the ECCO family with all its activities over the next two years!

The 18th Congress of ECCO in numbers

6,754 delegates attended the 18th Congress of ECCO in Copenhagen, Denmark

The 18th Congress of ECCO, Copenhagen, Denmark – Inflammatory Bowel Diseases 2023, held on March 1-4, 2023, attracted a total number of 6,754 delegates from 100 different countries. Since the inaugural ECCO Congress in 2006 in Amsterdam, at which there were 350 delegates, participant numbers have steadily increased, as shown in the graph below. Despite the COVID-19 outbreak in the beginning of 2020, we are happy that this high number of delegates had the chance to participate in the ECCO’23 Congress in Copenhagen.

    Dear IBD Colleagues and Friends, 

    After the previous two editions of our Annual Congress had to be conducted virtually due to the COVID-19 pandemic, we once again had the opportunity to share and exchange knowledge and ideas in person during the 18th Congress of ECCO, held from March 1-4, 2023. This was really exciting!

    First, the Educational Programme, which was scheduled prior to the official start of the ECCO Congress, covered activities for ECCO's different interest groups, including young gastroenterologists, surgeons, paediatricians, pathologists, IBD Nurses and allied health professionals and scientists. The Programme included two exciting imaging courses offered in collaboration with ESGAR & IBUS, the School for Clinical Trialists and our Basic Science and SciCom Workshops.

    At the recent 18th Congress of ECCO, Sebastian Zeissig (Dresden, Germany) stepped down as a member of the ECCO Scientific Committee. After two years of active membership, Sebastian became SciCom Chair back in 2020. Although this period was greatly affected by the pandemic, Sebastian made sure that ECCO continued to support clinical, translational and basic science. During his chairmanship, the different ECCO Fellowships, Grants and Travel Awards were streamlined and optimised. Together with the rest of the team, he spent a lot of energy in finding appropriate reviewers for the dozens of project proposals received every year. Sebastian was also the driving force behind the new ECCO Young Researcher Award, which was granted for the first time earlier this year. As SciCom Chair, he supervised two successful Scientific Workshops, one on precision medicine (together with Michael Scharl) and another on postoperative Crohn’s Disease recurrence (together with Yves Panis and Marc Ferrante). We thank Sebastian for his great enthusiasm, his perseverance and his friendship.

    Combination treatment with partial enteral nutrition and biologics as induction therapy for adults with active ileocolonic Crohn’s Disease: a pilot study

    Background & aim of research

    There is strong interest in investigating combination therapies for active Crohn’s Disease (CD) to improve response to biologics and to mitigate secondary loss of response, without increasing the risk of drug-associated side effects. Exclusive enteral nutrition is an established treatment for active CD, but tolerance is poor. In partial enteral nutrition (PEN) only part of the habitual diet is replaced by the proprietary formula, allowing patients to eat some normal food. PEN at high volume (>50% energy requirements) can prolong remission compared to unrestricted diet. Therefore, the aim of the present study is to compare clinical remission/response rates to standard treatment with adalimumab (ADA) between a group of CD patients on unrestricted diet and another group on 50% PEN. Secondary aims are to explore how these two treatments change the gut microbiome composition and its diet-related function.

    Assessment of desire and sexual function in Inflammatory Bowel Disease patients: a cross-sectional study with matched controls

    Background & aim of research

    Sexual dysfunction (SD) rates are higher in the Inflammatory Bowel Disease (IBD) patient population compared with the general population. Overall among IBD patients, low sexual desire and greater difficulty in achieving orgasms are the most frequently reported sexual problems. In addition, women report worse body image and lower sexual desire. Being diagnosed with major depression, undergoing surgery or suffering IBD symptoms are the usual triggers.

    Despite the importance of sexual well-being, there is a lack of research focusing on sexual desire in IBD patients. This study aims to assess the prevalence of sexual dysfunction and to analyse sexual desire from a dual viewpoint: a dyadic and a solitary perspective. The intention is to describe sexual function and its possible correlations with the presence of anxiety and depression, disease activity and quality of life.

    Recognizing the prevalence of sexual dysfunction in IBD patients can improve clinical practice and optimize resource planning for sexual healthcare. Early diagnosis and primary prevention can help address sexuality-related concerns in this population.

    Development of biomarker signatures as an alternative to endoscopy: looking beyond inflammation

    Background & aim of research

    In Crohn’s Disease (CD), the treat-to-target strategy has become the standard of care [1, 2]. This clinical concept consists in escalating/optimising the treatment (e.g. dose, frequency, type of drugs) until a state of remission (target) is achieved. Overall, treatment targets evolve towards a deeper level of remission and it is in this context that endoscopic remission has become a primary objective. However, endoscopy remains invasive and costly, is not well accepted by patients and does not allow tight control of disease activity. Thus, attention is turning to non-invasive biomarkers that can replace endoscopy. Our group recently made progress in monitoring disease activity with blood proteins. More precisely, we found distinct biological profiles to be associated with the risk of short-term and mid/long-term relapse in CD patients who stop infliximab [3–5]. By measuring 161 blood proteins, we captured a more complete picture of the disease activity than is achieved with classic inflammatory markers. Clearly, looking beyond inflammation is necessary in order to monitor disease activity more effectively. Based on our previous work, we aim to develop biomarker signatures as an alternative to endoscopy.

    iNKT cells immunomodulation and mucosal healing by microbiota-derived lactate (OCELOT)

    Background & aim of research

    Invariant natural killer T (iNKT) cells are unconventional T lymphocytes that play a critical role in mucosal immunity. Although iNKT cells sense the microbiota of IBD patients, promoting pro-inflammatory responses, their rapid responsiveness to the intestinal microenvironment can be harnessed to promote immunoregulatory rather than pro-inflammatory responses. OCELOT’s central hypothesis is that iNKT cells are the primary immune cells that sense microbiota-derived metabolic signals promoting the resolution of inflammation. In particular, OCELOT argues that microbiota-derived lactate can tightly control iNKT cell function, promoting mucosal tolerance while preventing T cell-mediated inflammation and tissue injury.

    Feeding immunity: development of a novel glycan-based dietary strategy for IBD prevention

    Background & aim of research

    Dietary interventions have been shown to ameliorate symptoms in patients with mild or moderate IBD. Nevertheless, these therapies are only effective for a subset of patients, raising the need for novel dietary intervention strategies that aim to prevent IBD development. Glycosylation is a major post-translational mechanism characterised by the addition of carbohydrate structures, called glycans, to essentially all cells. We have revealed that mucosal T cells from Ulcerative Colitis patients exhibit alterations in mucosal glycosylation, which positively correlate with T cell hyperactivity and disease severity. We have also demonstrated that mice deficient in branched N-glycosylation display increased susceptibility to severe colitis. Supplementation of these mice with glycans resulted in disease control via inhibition of Th1/Th17 immune responses.

    In this research we aim to explore whether dietary supplementation with glycans promotes a superior function for nutraceutical intervention to promote IBD prevention, characterising the effect of mucosal glycosylation reprogramming in shaping the intestinal environment.

    Ascertaining the role of the appendix in inflammatory bowel disease in a population-based cohort

    Background & aim of research

    Appendectomy at age <20 years for appendicitis or mesenteric lymphadenitis has been associated with a lower risk of Ulcerative Colitis (UC), but this association has not been detected when appendectomy is performed at an older age or for non-specific abdominal pain. Similar findings have been reported upon combining data from Swedish and Danish registers.  However, in a Danish cohort study of familial units, individuals who had first-degree relatives with appendicitis, but no personal history of appendicitis, at age <20 years also had a lower risk of UC. This risk was even lower in those with a family history of UC. 

    Interventional studies on elective appendectomy for UC therapy are underway. The impact of appendiceal inflammation on UC outcomes, including cancer, are not well understood. 

    The overall aim of this study is to understand the role of the appendix (appendicitis and appendectomy) in IBD risk and IBD outcomes.
