Dear ECCO Friends,

Research and education are priorities in the ECCO Community. Autumn is a great time for exciting new ECCO events and is the perfect time to start planning your attendance at the ECCO’23 Congress in Copenhagen – where we finally meet again in person. After two years of online Congress meetings, ECCO’23 will be hopefully again face to face, providing great opportunities for networking with ‘old’ friends and establishing new links and collaborations.

Comparative accuracy of TransPerineal UltraSound (TPUS) versus Magnetic Resonance Imaging (MRI) for the assessment of perianal fistulae in patients with Crohn’s Disease: a prospective observational longitudinal cohort study

Background & aim of research

Magnetic resonance imaging (MRI) is the first-line imaging modality for monitoring of perianal disease in patients with Crohn’s Disease (CD). However, its use depends on local availability, costs and expertise. Few studies are available on the role of transperineal ultrasound (TPUS). Performing MRI alone in all patients would impose a substantial expense on the health service and would represent a limitation for the many patients who cannot tolerate the procedure (e.g. owing to claustrophobia). For this reason, we urgently need a painless, non-invasive, cost-effective and widely available modality to assess perianal disease and predict disease outcomes. In this observational prospective study, we investigate the accuracy of TPUS versus pelvic MRI in the diagnosis and monitoring of medical and surgical treatment of perianal fistulae in CD patients.

Background & aim of research

It is currently unknown whether diet influences inflammation in Ulcerative Colitis (UC). Observational and experimental data suggest that modulating sulphide within the luminal environment may have therapeutic potential for UC. The aim of this trial is therefore to determine whether a sulphide-reducing diet, designed to attenuate excess microbial production of potentially noxious gases in the colon, can induce remission in UC.

Background & aim of research

We have pioneered in studying ex vivo extracellular matrix (ECM) remodelling, which is known for its key role in Crohn’s Disease (CD) fibrostenosis. By adding disease-relevant enzymes on the ECM of CD patients’ intestine, we identified numerous matrikines (specific ECM peptide fragments) unique in CD fibrostenosis. Peptidomics software analysis showed specific likelihood for bioactivity for 19 of those matrikines (Giuffrida et. al, unpublished data) ().

This project aims to explore the bioactivity of matrikines in CD fibrostenosis in vitro.

Decoding the neuroimmune crosstalk in Inflammatory Bowel Diseases

Background & aim of research

Inflammatory Bowel Disease (IBD) results from an anomalous interaction between genetic, environmental, immunoregulatory and microbial-derived factors. IBD- associated specific mutations include genes involved in microbial recognition, such as mutations in the Toll-like receptor 4 (TLR4). Beside controlling host defence responses, TLR4 modulates enteric nervous system (ENS) activity, gut motility and repair processes following an insult. TLR4 deficiency in mice leads to significant ENS alterations, characterised by modified gut motility and susceptibility to inflammation. The findings of decreased gut catecholamine levels in IBD patients and the onset of milder experimental colitis after sympathectomy highlight the role of the nervous system as a key regulator of immune responses. Therefore, our research project aims to decode the neuroimmune interactions between the catecholaminergic system and innate immune sensor TLR4 in dinitrobenzene sulphonic acid (DNBS)-induced ileitis.

Intestinal epithelial cell stress modulates enteric fibroblastic and neuronal profiles in Inflammatory Bowel Disease

Background & aim of research

Genetic studies have implicated the autophagy gene ATG16L1 and the endoplasmic stress (ER) gene XBP1 in the pathogenesis of Inflammatory Bowel Disease (IBD). Indeed, spontaneous inflammation develops in mice lacking ATG16L1 or XBP1 expression in intestinal epithelial cells (IEC). Because of the dominant role of failing autophagy and ER stress in IBD, we hypothesise that IEC stress contributes to intestinal fibrosis, gut dysmotility and pain during colitis.

This project aims, for the first time, to thoroughly comprehend the role of crucial IBD epithelial stress factors (i.e. ATG16L1 and XBP1 impairments) in enteric fibroblasts and neurons and to explore potential future intervention points.

Background & aim of research

Perianal fistulising Crohn’s Disease (pCD) is associated with poor outcomes and impaired quality of life. It remains difficult to manage despite medical and surgical advancements, likely due to poor understanding of the underlying immunology. Previous multiparameter flow cytometry work in our lab on immune cells isolated from peripheral blood and fistula curettage samples showed expansion of iNKT cells in perianal fistula compared to peripheral blood. Furthermore, iNKTs have been suggested to have a potential role in key processes in fistula pathogenesis, namely epithelial-to-mesenchymal transition and extracellular matrix degradation. The role of iNKTs in inflammation remains poorly defined and their function in human IBD is largely unexplored. Therefore, in this experiment we aim to further define their role in the pathogenesis of perianal fistula.

Caring and management of patients with Inflammatory Bowel Disease: a focus on specialist nursing interventions

Background & aim of research

The number of specialist nurses dedicated to the care and management of patients with Inflammatory Bowel Disease (IBD) is increasing across Europe, and their role is widening. Despite the increased interest in the opportunities associated with this emerging healthcare professional role, from the perspectives of both patients and clinicians, scarce evidence is available on the effectiveness of specialist nursing interventions. An in-depth review of the impact of specialist nursing interventions on the care and management of patients with IBD, and especially on the health-related quality of life (QoL), is needed.

The main outcome of interest in this context is clinical remission (the proportion of patients in whom remission is achieved or maintained). Additional outcomes are: the proportion of hospital admissions/readmissions, the length of hospital stay, clinical improvement, patients’ QoL and the effectiveness of treatment.

Background & aim of research

JAK inhibition has emerged as a promising novel therapeutic strategy in IBD. However, only a subgroup of patients responds to JAK inhibitors and there are currently no predictive markers available that predict sustained response. Our recent work strongly indicates that loss-of-function variants in the PTPN2 gene might serve as predictive markers for therapeutic effectiveness, and the main goal of this project is to define whether PTPN2 dysfunction can serve as a predictor for efficacious JAK inhibitor therapy.
