Familial aggregation in Inflammatory Bowel Disease: a next-generation sequencing study

Aim of research

Family history of Inflammatory Bowel Disease (IBD) is the strongest risk factor for IBD. Currently, however, there is incomplete understanding of the contribution of genetic risk to familial aggregation of IBD. We aim to identify the genetic basis of familial aggregation in multiple-affected IBD families and to identify shared genetic susceptibility variants between IBD and other diseases using families suffering from IBD and concomitant diseases.

The role of PTPN23 in intestinal inflammation and colitis-associated cancer

Aim of research

Inflammatory Bowel Disease with colonic involvement predisposes patients to develop colitis-associated cancer (CAC) due to chronic inflammation. Protein tyrosine phosphatases (PTP) play a critical role in the regulation of signalling cascades involved in IBD and oncogenesis. Particularly PTPN23 deletion has recently been associated with epithelial cancers. However, a role of PTPN23 in IBD and CAC/CRC has not yet been investigated. Based on previous data, our hypothesis is that PTPN23 controls intestinal epithelial cell (IEC) homeostasis and proliferation. The overarching aim of our project is to investigate the role of PTPN23 in intestinal homeostasis and inflammation.

Predictive (longitudinal) gut microbial markers for the diagnosis of fatigue in IBD patients

Aim of research

Fatigue is an important clinical problem in patients with IBD in remission and those with active disease. It results in a decrease in quality of life and impaired work productivity. However, little is known about its aetiology and pathophysiology, which impairs our ability to effectively treat this symptom. Evidence suggests that the intestinal microbiota act as a mediator in the bidirectional communication between the nervous system and the gut. Recent research by our group demonstrated a strong and statistically significant correlation between the microbiome and increasing fatigue scores. However, little is known about the changes in the composition of the intestinal microbiome and their influence on the diagnosis and course of fatigue.

Our aim is to identify the underlying biological mechanisms involved in IBD-related fatigue, especially the influence of longitudinal changes in the intestinal microbiome, and to reveal IBD fatigue-specific patterns.

Improving clinical outcomes for IBD patients undergoing colorectal surgery by using a clinically developed patient-centred mobile application

Aim of research

Enhanced Recovery After Surgery (ERAS) is a multidisciplinary and multimodal protocol focussing on perioperative care which has proved successful in improving clinical outcomes for patients undergoing colorectal resection. Adequate compliance with the ERAS protocol is associated with improved clinical outcome, but there is an additional gain in involving patients actively in their efforts towards recovery. Whether outcomes may be further improved by specifically focussing on active patient involvement has not previously been investigated. A mobile application with an integrated ERAS protocol could be of great potential. However, the integrated ERAS protocol might need adaptation to meet the specific needs of patients with Inflammatory Bowel Disease (IBD) undergoing colorectal surgery. 

The main objective of this study is to investigate whether a CE-marked, clinically developed patient-centred mobile application, which can be used for multiple colorectal surgical pathways, enhances outcomes for IBD patients by stimulating patient empowerment and actively involving patients in the ERAS care pathway.

Dose-related differential effects of vedolizumab on leukocyte subsets

Aim of research

The anti-α4β7 integrin antibody vedolizumab is successfully used for the clinical treatment of IBD. However, some details of its mechanisms are still not clear. Moreover, whether dose intensification of vedolizumab therapy may also increase response rates is the subject of ongoing debate, as some previous studies have suggested a non-linear exposure–efficacy correlation. Since only a portion of patients benefit from vedolizumab therapy, further translational insights into these aspects are an important unmet need for therapy optimisation and the development of personalised treatment approaches.

Based on preliminary data we hypothesise that vedolizumab has a differential preference of binding to distinct leukocyte subsets (e.g. effector and regulatory T cells), resulting in specific profiles of targeted immune cells at a certain level of vedolizumab exposure. This may explain the suggested non-linear exposure–efficacy correlation.  Therefore, we aim to elucidate dose-dependent binding characteristics to leukocyte subsets and related functional aspects in vitro and in vivo.

The exposome and personalised medicine in IBD

Behrooz Z. Alizadeh, EpiCom Member

Introduction

In the past few decades, the incidence of Inflammatory Bowel Diseases (IBD) started rising especially in industrialised Western countries, affecting more than two million Americans and Europeans [1–3]. At the turn of the twenty-first century, however, IBD became a global disease, rapidly affecting the Eastern and Southern developing nations [3–5]. So, the global prevalence of IBD is currently estimated at 0.7% and is expected to increase to 1% by 2030 [1, 3, 6].The rise in IBD has coincided with an increase in urbanisation, sanitisation, and adoption of a Western lifestyle [4], as well as advances in infrastructure, better access to healthcare, and increased awareness of community following socioeconomic development. It is therefore assumed that the primary suspect underlying the globalisation of IBD is the alteration of the human environment, called the exposome (meaning exposures to environmental and lifestyle factors throughout life, starting at conception), and the associated embracing of Western lifestyles by other nations [6].

GRADE Workshop at ECCO'21

Previous participants in GuiCom workshops at recent ECCO Congresses will have learned much about the adoption of GRADE methodology into the ECCO Guideline process and the practicalities of working with the GRADE process. For ECCO 2021, GuiCom wanted to offer participants something a little different. The GuiCom 2021 Workshop will therefore seek to place the GRADE process within the current controversies and ‘hot topics’ with respect to guidelines.

Nutritional Management of Iron Deficiency

Catherine Wall, D-ECCO Member

Iron deficiency and iron-deficiency anaemia (IDA) are characterised by fatigue and reduced capacity for normal activities of daily living and consequently poorer quality of life. Iron deficiency is estimated to affect 60%–80% of people with IBD at some point [1]. Recurrent iron deficiency is also common and is estimated to occur in 30% of patients [1]. Given the prevalence of iron deficiency, some patients and practitioners have learned to accept this impaired quality of life as an unavoidable consequence of IBD [2]. However, correction of iron deficiency in patients without anaemia can result in improved quality of life and less fatigue and should, therefore, be an important treatment goal.
