Molecular Nature

Intestinal homoeostasis is a complex affair. We are just beginning to appreciate the molecular nature of the crosstalk that allows happy coexistence between the commensal resident microbiota and the gastrointestinal (GI) mucosal immune system. Both microbial and host components involved in this interplay are being increasingly identified and studied. A better understanding of these multifaceted interactions holds the key for unlocking the cellular events responsible for gut inflammatory conditions such as Crohn's disease and ulcerative colitis.

Inflammatory bowel disease, a group of inflammatory conditions of the colon and small intestine, principally includes ulcerative colitis and Crohn's disease. Current attention to inflammatory bowel disease is promoted by worldwide increase in its incidence and morbidity as well as shortcomings of existing treatment. Extraintestinal (musculoskeletal, skin, renal, hepatic etc.) manifestations of inflammatory bowel disease significantly complicate the diagnosis and may predict the development of intestinal symptoms. In certain cases, the severity of extraskeletal manifestations may exceed that of the main diagnosis. Here we describe a clinical example of this scenario.

Introdução: A Doença Inflamatória Intestinal que compreende, principalmente, a Doença de Crohn e a Retocolite Ulcerativa, consiste em um grupo de condições inflamatórias crônicas que afetam predominantemente o trato gastrointestinal de indivíduos suscetíveis expostos a fatores de risco ambientais. Estudos recentes demonstram que a incidência e a prevalência da doença vêm aumentando em diferentes regiões do mundo. Em paralelo, há crescimento na utilização de imunomoduladores e terapias biológicas, tornando necessária a análise de seus riscos e impactos. Devido às terapias de longa duração com medicamentos sujeitos a efeitos nocivos, pacientes em vigência de tratamento podem evoluir com reações adversas. Objetivos: Analisar a ocorrência de reações adversas a medicamento durante o tratamento farmacológico de pacientes do Ambulatório de Referência de Doenças Inflamatórias Intestinais do Hospital Santa Casa de Misericórdia em Vitória – ES. Métodos: Estudo observacional e analítico de pesquisa documental retrospectiva através da coleta de dados durante o mês de outubro de 2020, em registros de pacientes em acompanhamento clínico. Conclusão: O perfil de reações adversas a medicamentos do estudo concordou majoritariamente com dados da literatura. Por meio desses dados será possível desenvolver estratégias voltadas ao rastreio, prevenção e redução das reações adversas a medicamentos, contribuindo para a diminuição da morbimortalidade e dos custos inerentes ao tratamento.Palavras chave: Reações adversas relacionadas a medicamentos, Efeitos colaterais, Doença de Crohn, Colite ulcerativa, Doenças inflamatórias intestinais ABSTRACT Introduction: Inflammatory Bowel Disease, which mainly comprises Crohn’s Disease and Ulcerative Colitis, consists of a group of chronic inflammatory conditions that predominantly affect the gastrointestinal tract of susceptible individuals exposed to environmental risk factors. Recent studies show that the incidence and prevalence of the disease has been increasing in different regions of the world. In parallel, there is a growth in the use of immunomodulators and biological therapies, making it necessary to analyze their risks and impacts. Due to long-term therapies with drugs subject to harmful effects, patients undergoing treatment may evolve with adverse reactions. Objective: To analyze the occurrence of adverse reactions to drugs during the pharmacological treatment of patients at the Reference Clinic for Inflammatory Bowel Diseases at Hospital Santa Casa de Misericórdia in Vitória - ES (HSCMV). Methods: This is an observational and analytical study of retrospective documentary research was carried out through of data during the month of October 2020, in patient records under clinical follow-up. Conclusion: The adverse drug reactions (ADR) profile of the study mostly agreed with data from the literature. Through these data, it will be possible to develop strategies aimed at screening, preventing and reducing ADRs, contributing to the reduction of morbidity and mortality and costs inherent to treatment.

Abstract Background During inflammatory bowel disease the mucosal immune system is altered. The mucosal immune cells are communicating through the various cytokines. Single cell and small volume RNA-seq and proteomics approaches make the investigation of cytokine networks plausible However the lack of specific resources make such efforts hard. Methods To address this need in this project, we built a cell-cell communication map, CytokineLink, which collates cytokine mediated intercellular interactions. CytokineLink collects the cytokine-cytokine receptor interactions from the OmniPath, immuneXpresso and immunoGlobe databases. We demonstrate the applicability of CytokineLink by presenting how cytokine feedback loops are built and altered during Ulcerative Colitis. We mapped single-cell RNA-seq expression data from inflamed and uninflamed Ulcerative Colitis biopsies to the interactions between cytokines and cytokine receptors, and then we compared the specific cytokine-mediated cell-cell interactions. Results Using our approach, we were able to point out major differences in cell-cell communication between inflamed and uninflamed conditions, and identify key cytokine changes. For example, the generally anti-inflammatory cytokine IL-10 is produced by regulatory T-cells in both conditions. However the IL-10 receptor positive cells are altered between the inflamed and uninflamed condition: dendritic cells and innate lymphocytes did not express the receptor in the sufficient amount. It suggests that not the cytokine level directly but the receptor level alterations are involved in ulcerative colitis. Also the chemokine CXCL12 was expressed by the inflammatory fibroblasts. This cytokine promotes the T-cell recruitment and through that inflammation. Conclusion With CytokineLink, researchers are capable to pinpoint the most important interactions in the changing mucosal immune system and propose novel therapeutic approaches. We are currently developing a website and easy to follow workflows to make CytokineLink available.

The incidence, prevalence, and cost of care associated with diagnosis and management of inflammatory bowel disease are on the rise. The role of gut microbiota in the causation of Crohn's disease and ulcerative colitis has not been established yet. Nevertheless, several animal models and human studies point towards the association. Targeting intestinal dysbiosis for remission induction, maintenance, and relapse prevention is an attractive treatment approach with minimal adverse effects. However, the data is still conflicting. The purpose of this article is to provide the most comprehensive and updated review on the utility of prebiotics and probiotics in the management of active Crohn’s disease and ulcerative colitis/pouchitis and their role in the remission induction, maintenance, and relapse prevention. A thorough literature review was performed on PubMed, Ovid Medline, and EMBASE using the terms “prebiotics AND ulcerative colitis”, “probiotics AND ulcerative colitis”, “prebiotics AND Crohn's disease”, “probiotics AND Crohn's disease”, “probiotics AND acute pouchitis”, “probiotics AND chronic pouchitis” and “prebiotics AND pouchitis”. Observational studies and clinical trials conducted on humans and published in the English language were included. A total of 71 clinical trials evaluating the utility of prebiotics and probiotics in the management of inflammatory bowel disease were reviewed and the findings were summarized. Most of these studies on probiotics evaluated lactobacillus, De Simone Formulation or Escherichia coli Nissle 1917 and there is some evidence supporting these agents for induction and maintenance of remission in ulcerative colitis and prevention of pouchitis relapse with minimal adverse effects. The efficacy of prebiotics such as fructooligosaccharides and Plantago ovata seeds in ulcerative colitis are inconclusive and the data regarding the utility of prebiotics in pouchitis is limited. The results of the clinical trials for remission induction and maintenance in active Crohn's disease or post-operative relapse with probiotics and prebiotics are inadequate and not very convincing. Prebiotics and probiotics are safe, effective and have great therapeutic potential. However, better designed clinical trials in the multicenter setting with a large sample and long duration of intervention are needed to identify the specific strain or combination of probiotics and prebiotics which will be more beneficial and effective in patients with inflammatory bowel disease.

Abstract Background and aims The COVID-19 pandemic has led to a deep reorganization of hospital services including inflammatory bowel disease (IBD) units. In this situation, conversion of in-person routine follow-up visits into phone consultations might be necessary. Here we explored the feasibility of using the validated Crohn’s Disease (CD) or Ulcerative Colitis (UC) Patient-Reported Outcomes Signs and Symptoms (CD- and UC-PRO/SS) to collect data about abdominal symptoms (abdominal/S) and bowel signs and symptoms (bowel/SS) remotely. Methods CD- and UC-PRO/SS were collected during phone consultations and compared among patients with active and inactive disease. The effectiveness of therapeutic intervention in patients with active disease was assessed by PRO/SS variation. Results Twenty-one CD and 56 UC patients were evaluated by phone. Six (28.6%) CD and 15 (26.8%) UC patients were considered to have active disease. In CD the bowel/SS but not the abdominal/S module was significantly higher in active patients (mean bowel/SS 2.50 [SE ± 0.44] active vs 0.76 [SE ± 0.18] remission, p = 0.008, AUC 0.87; mean abdominal/S 1.11 [SE ± 0.38] active vs 0.24 [SE ± 0.13] remission, p = 0.066). UC-PRO/SS measures were significantly higher in active patients as compared to patients in remission (median bowel/SS 1.63 [SE ± 0.24] active vs 0.33 [SE ± 0.04] remission; p < 0.0001, AUC 0.91; mean abdominal/S 1.03 [SE ± 0.24] vs 0.37 [SE ± 0.12]; p = 0.009, AUC 0.71). Therapy was escalated in 12 patients (3 CD and 9 UC) due to disease relapse. Therapy escalation resulted in the reduction of PRO/SS as evaluated at the subsequent phone consultation. Conclusions PRO/SS might represent a feasible tool to evaluate disease activity and therapy outcome in IBD patients during periods of limited access to outpatient clinics.

Adhesion molecules regulate the influx of leukocytes in normal and inflamed gut. They are also involved in local lymphocyte stimulation and antigen presentation within the intestinal mucosa. In intestinal inflammation, many adhesion molecules are upregulated, but α4-integrins most likely hold a key position in directing leukocytes into the inflamed bowel wall. Therapeutic compounds directed against trafficking of leukocytes have been designed and are being developed as a novel class of drugs in the treatment of Crohn's disease and ulcerative colitis. This review deals with the immunological aspects of leukocyte trafficking focused on gut homing of T cells. Second, the changes in adhesion molecules and T cell trafficking during intestinal inflammation are discussed. Finally, we review the clinical data that have been gathered with respect to the therapeutic potential and the safety of antiadhesion molecule treatment. Antegren, or natalizumab, a humanized anti-α4 integrin IgG4 antibody, has been most extensively evaluated and may be close to registration. A more specific humanized α4β7-integrin MLN-02 has shown preliminary clinical efficacy in ulcerative colitis, and both antergren and MLN-02 appear to be very safe. Trials with the anti-ICAM-1 antisense oligonucleotide ISIS-2302 in steroid refractory Crohn's disease have provided conflicting efficacy data. In the near future, some of these novel biological agents may prove valuable therapeutic tools in the management of refractory inflammatory bowel disease, although it is too early to define the patient population that will benefit most from these agents.

Abstract Aim Patients with inflammatory bowel disease (IBD) are likely to undergo several abdominal operations and may thus be at increased risk for incisional hernia repair (IHR). The aim of the present study was to investigate risk and predictors of IHR in patients undergoing surgery for ulcerative colitis (UC) or Crohn’s disease (CD). Material and Methods Nationwide register-based study (1996-2018). Patients were followed from date of first abdominal operation until the date of the first IHR. Cumulative incidence proportion were estimated treating death as competing risk. Cox proportional hazard regression was used to explore pre-study defined predictors of IHR. Results Patients with inflammatory bowel disease (IBD) are likely to undergo several abdominal operations and may thus be at increased risk for incisional hernia repair (IHR). The present study analyzed the risk and predictors of IHR in patients undergoing surgery for ulcerative colitis (UC) or Crohn’s disease (CD). Conclusions The risk for incisional hernia repair is relatively low after IBD-surgery, although increased in UC compared with CD patients. Hernia repair predictors varied between UC and CD patients.

Imagine having to empty your bowel eight or ten times a day and experiencing constant panic and fear about the location of toilet facilities. Imagine experiencing constant tiredness that impacts on all aspects of your life including work, family and social life. These are just two examples of experiences commonly suffered by individuals with a condition called inflammatory bowel disease. These people are burdened with symptoms which impact on their daily lives. This research aims to provide healthcare professionals with an understanding of the extent to which individuals with inflammatory bowel disease experience symptom burden and to identify what symptoms are most problematic. Crohn’s disease and ulcerative colitis collectively termed as inflammatory bowel disease are complex disorders. In the United Kingdom, collectively Crohn’s disease and ulcerative colitis affects approximately one person in every 250 of the population. Ulcerative colitis affects up to 120,000 people in the UK, or every 1 ...
