Mucosal immunology and probiotics.

2013

The cross-talk between the mucosa-associated immune system and microbiota is critical in mucosal tissue homeostasis as well as in protection against infectious and inflammatory diseases occurring at mucosal sites. This recent evidence has paved the way to therapeutic approaches aimed at modulating the mucosa-associated immune system using probiotics. Different strains of probiotics possess the ability to finely regulate dendritic cell (DC) activation, polarizing the subsequent T cell activity toward Th1 (e.g. Lactobacillus (Lb) acidophilus), Th2 (Lb.reuteri and Bifidobacterium bifidum) or, as more recently demonstrated, Th17 responses induced by specific strains such as Lb.rhamnosus GG and …

P178 Remote monitoring as an effective management strategy in inflammatory bowel disease: the lesson from COVID-19 pandemic

2021

Abstract Background During the COVID-19 outbreaks many IBD clinics in Italy adopted a remote monitoring approach both to ensure an adequate follow-up of patients with inflammatory bowel disease (IBD) and respect the rules of social distancing, while access to hospital was restricted. Aim of the study was to perform a survey on IBD patients submitted to remote monitoring in our tertiary referral center in order to assess adherence and patients’ perceptions and satisfaction as well as their opinions for future monitoring. Changes in disease activity and Quality of Life were also evaluated. Methods Consecutive patients with IBD scheduled for follow-up visits were switched to remote monitoring …

Pathogenesis of Crohn’s disease: Bug or no bug

2015

The possibility of an infectious origin in inflammatory bowel disease (IBD) has been postulated since the first description of Crohn’s disease (CD). Many observations implicate bacteria as a trigger for the development of CD: lesions occur in regions with higher bacterial concentrations; aphthous ulcers occur in Peyer’s patches; inflammation resolves when the fecal stream is diverted and is reactivated following reinfusion of bowel contents; severity of the disease is correlated with bacterial density in the mucosa; granulomas can contain bacteria; and susceptible mice raised in germ-free conditions develop inflammation when bacteria are introduced in the 1990’s, several studies sought to e…

Chronic Urticaria as a presenting symptom of Crohn’s disease.

2009

Clinical presentation of Crohn’s disease (CD) may be variable according to the location and the intensity of the inflammation. Some patients may have atypical symptoms which could delay the diagnosis. We report the first case of chronic urticaria related to a subclinical, complicated CD. Although the pathologic mechanism of this association was unclear in our patient, this case suggests that in patients with unexplained chronic urticaria it is opportune to investigate for a possible CD, even if there are no or few specific symptoms of intestinal inflammatory disease.

DOP21 Role of P2X7 in intestinal fibrosis and inflammasome activation: Relevance in Crohn′s Disease

2021

Abstract Background Crohn’s disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract whose etiology is unknown. CD is associated with complications such as fibrosis or fistula, which cannot be pharmacologically reversed, requiring repeated surgery. Although a profibrotic effect of the P2X7 receptor has been described in some scenarios such as lung, heart and liver, its role in intestinal fibrosis has not been analysed yet. Given the crosstalk between fibrosis and inflammasome, we aim to analyze the relevance of P2X7 in intestinal fibrosis and inflammasome activation. Methods Surgical intestinal resections of CD patients and healthy ileum of carcinoma patients were obtai…

P260 Adaptation of TECCU App based on patients’ perceptions for telemonitoring inflammatory bowel disease: A qualitative study using focus groups

2020

Abstract Background Despite the continuous adaptation of eHealth systems for patients with inflammatory bowel disease (IBD), a significant disconnection persists between users and developers. Since non-adherence remains high, it is necessary to better understand the patients’ perspectives on telemonitoring for IBD. The aim of this study was to adapt the TECCU app to the preferences and needs of IBD patients. Methods A qualitative study was carried out using successive focus groups of IBD patients. Meetings were audio-recorded and a thematic analysis approach was employed until data saturation was achieved. The first group included patients who had used the TECCU app in a pilot clinical tria…

Study of the Viral and Microbial Communities Associated With Crohn's Disease: A Metagenomic Approach

2013

OBJECTIVES: This study aimed to analyze and compare the diversity and structure of the viral and microbial communities in fecal samples from a control group of healthy volunteers and from patients affected by Crohn's disease (CD). METHODS: Healthy adult controls (n=8) and patients affected by ileocolic CD (n=11) were examined for the viral and microbial communities in their feces and, in one additional case, in the intestinal tissue. Using two different approaches, we compared the viral and microbial communities in several ways: by group (patients vs. controls), entity (viruses vs. bacteria), read assembly (unassembled vs. assembled reads), and methodology (our approach vs. an existing pipe…

P228 Cytomegalovirus Infection: is it a cause of flare-up in inflammatory bowel diseases?

2020

Abstract Background The presence of CMV in blood is quite common in patients with severe flares of ulcerative colitis (UC) and Crohn’s disease (CD) and seems to predict an adverse outcome. The impact of antiviral treatment on CMV in this setting (indications and drug options) is an unresolved issue. Our aim was to reassess the CMV role in patients with IBD hospitalised for severe exacerbations, analysing the relationship between CMV positivity, clinical characteristics, antiviral therapy and disease outcomes. Methods We evaluated a homogeneous cohort of 97 consecutive patients with IBD hospitalised from 2012 to 2018. Data regarding age, gender, smoke, familial predisposition, type of IBD, e…
