Confocal Endomicroscopy Identifies Loss of Local Barrier Function in the Duodenum of Patients with Crohnʼs Disease and Ulcerative Colitis
2014
Background: Increased cell shedding with gap formation and local barrier dysfunction can be identified endomicroscopically in the terminal ileum of patients with inflammatory bowel disease. We aim to evaluate whether these changes are also present in the duodenum of patients with inflammatory bowel disease. Methods: Fifteen patients with Crohn's disease (CD), 10 patients with ulcerative colitis (UC), and 10 controls underwent fluorescein-aided confocal laser endomicroscopy (CLE). CLE was performed on macroscopically normal antral and duodenal (D1, D2, D3, D4) mucosa. Representative CLE images were prospectively analyzed. Images were scored for the number of epithelial gaps, cell shedding, a…
Risk of Colorectal High-Grade Dysplasia and Cancer in a Prospective Observational Cohort of Patients with Inflammatory Bowel Disease.
2013
International audience; BACKGROUND AND AIMS:: There is an unclear risk of colonic high-grade dysplasia (HGD) and colorectal cancer (CRC) among patients with inflammatory bowel disease (IBD) treated with immunosuppressants. We analyzed data on CRC development among patients with IBD enrolled in the observational cohort Cancers et Surrisque Associé aux Maladies Inflammatoires Intestinales En France (CESAME). METHODS:: We followed and collected data from 19,486 patients with IBD (60.3% with Crohn's disease, 30.1% receiving thiopurine therapy) enrolled in CESAME from May 2004 and June 2005, and followed until December 2007. When the study began, 2841 patients (14.6%) were characterized as havin…
Cytokine Gene Transcription By NF-kappaB Family Members in Patients with Inflammatory Bowel Disease
1998
We examined the expression of the transcription factor NF-kappa B, a nuclear trans-acting factor known to play a key role in cytokine gene regulation, in patients with inflammatory bowel disease (IBD). It was found that LP macrophages in Crohn's disease (CD) and ulcerative colitis (UC) display high levels of NF-kappa B DNA-binding activity accompanied by an increased production of interleukin (IL)-1, IL-6, and tumor necrosis factor (TNF) alpha. Western blot studies showed an increased expression of the p50 and c-rel subunits of NF-kappa B; however, the most striking finding was an increased expression level of NF-kappa B p65 in patients with CD and UC. Selective downregulation of p65 in IBD…
Bacteria-specific T-cell clones are selective in their reactivity towards different enterobacteria or H. pylori and increased in inflammatory bowel d…
1996
In the present study the authors investigated the T-cell response to different enterobacteria or Helicobacter pylori and tested the hypothesis that the frequency of bacteria-specific T cells is increased in the intestine of patients with active inflammatory bowel disease (IBD), i.e. Crohn's disease (CD) and ulcerative colitis (UC). The analysis of a large panel of T-cell clones (Tc) (n = 888) from peripheral blood, non-inflamed and inflamed intestine from IBD patients and control individuals shows that both peripheral blood and intestinal T-cell clones were selectively stimulated by either Salmonella typhimurium, Yersinia enterocolitica 03, Escherichia coli or Helicobacter pylori sonicates,…
Identification of Epigenetic Methylation Signatures With Clinical Value in Crohn's Disease.
2019
INTRODUCTION: DNA methylation is an epigenetic mechanism that regulates gene expression and represents an important link between genotype, environment, and disease. It is a reversible and inheritable mechanism that could offer treatment targets. We aimed to assess the methylation changes on specific genes previously associated with Crohn's disease (CD) and to study their possible associations with the pathology. METHODS: We included 103 participants and grouped them into 2 cohorts (a first [n = 31] and a second validation [n = 72] cohort), with active CD (aCD) and inactive CD (iCD) and healthy participants (CTR). DNA was obtained from the peripheral blood and analyzed by the Agena platform.…
A Cytologic Assay for Diagnosis of Food Hypersensitivity in Patients With Irritable Bowel Syndrome
2010
BACKGROUND & AIMS: A percentage of patients with symptoms of irritable bowel syndrome (IBS) suffer from food hypersensitivity (FH) and improve on a food-elimination diet. No assays have satisfactory levels of sensitivity for identifying patients with FH. We evaluated the efficacy of an in vitro basophil activation assay in the diagnosis of FH in IBS-like patients. METHODS: Blood samples were collected from 120 consecutive patients diagnosed with IBS according to Rome II criteria. We analyzed in vitro activation of basophils by food allergens (based on levels of CD63 expression), as well as total and food-specific immunoglobulin (Ig)E levels in serum. Effects of elimination diets and dou…
Telemonitoring of Crohn's Disease and Ulcerative Colitis (TECCU): Cost-Effectiveness Analysis.
2019
Background Although electronic health interventions are considered safe and efficient, evidence regarding the cost-effectiveness of telemonitoring in inflammatory bowel disease is lacking. Objective We aimed to evaluate the cost-effectiveness and cost-utility of the Telemonitorización de la Enfermedad de Crohn y Colitis Ulcerosa (Telemonitoring of Crohn’s Disease and Ulcerative Colitis [TECCU]) Web platform (G_TECCU intervention group) for telemonitoring complex inflammatory bowel disease, compared with standard care (G_control) and nurse-assisted telephone care (G_NT intervention group). Methods We analyzed cost-effectiveness from a societal perspective by comparing the 3 follow-up method…
Adalimumab in steroid-dependent Crohn's disease patients: prognostic factors for clinical benefit.
2012
Background: Corticosteroids are effective in the treatment of Crohn's disease but some patients relapse during tapering or after discontinuation. We report data on efficacy and prognostic factors of response of adalimumab in steroid-dependent patients. Methods: In all, 110 steroid-dependent patients were treated with adalimumab (80/40 or 160/80 mg every other week followed by 40 mg every other week). Clinical remission was defined as steroid discontinuation without symptomatic recurrence and clinical response as the reduction or maintenance of the initial Crohn's Disease Activity Index (CDAI) value reducing steroid dosage but without its discontinuation at week 6 and at the end of follow-up…
Inflammatory Bowel Disease as a Precondition for Stroke or TIA: A Matter of Crohn's Disease Rather than Ulcerative Colitis.
2020
Abstract Background As a chronic systemic inflammation may be associated with an increased risk of vascular events, the aim of the present study was to assess the incidence of stroke and transient ischemic attack (TIA) in patients with inflammatory bowel disease over a period of 15 years. Methods This cohort study included patients for whom the initial diagnosis of an inflammatory bowel disease (IBD) (Crohn's disease: CD and ulcerative colitis: UC) was documented anonymously between 2000 and 2015 in 1,262 general practices in Germany. IBD patients were matched to patients without IBD using propensity scores based on age, sex, physician, co-diagnoses and co-therapies. Cox regression models w…
Alexithymia and personality traits of patients with inflammatory bowel disease
2017
AbstractPsychological factors, specific lifestyles and environmental stressors may influence etiopathogenesis and evolution of chronic diseases. We investigate the association between Chronic Inflammatory Bowel Diseases (IBD) and psychological dimensions such as personality traits, defence mechanisms, and Alexithymia, i.e. deficits of emotional awareness with inability to give a name to emotional states. We analyzed a survey of 100 patients with IBD and a control group of 66 healthy individuals. The survey involved filling out clinical and anamnestic forms and administering five psychological tests. These were then analyzed by using a network representation of the system by considering it a…
