Prevalence of Respiratory Impairment During IBD
Chronic Obstructive Pulmonary DiseaseAsthma2 morePatients will be recruited during a routine consultation with a physician in the hepato-gastroenterology department. At the end of the consultation, patients will have to complete the following questionnaire: "European Community Respiratory Health Survey" which allows the screening of patients at risk of chronic respiratory diseases (asthma, COPD, bronchiectasis, emphysema). In the event of a declaration of functional respiratory signs, a consultation with a pulmonologist will be systematically proposed. At the end of this consultation, if the doctor deems it necessary, further investigations will be proposed and/or regular follow-up organised. The main objective of this study is to estimate the prevalence of respiratory symptoms leading to a diagnosis of chronic respiratory disease in patients with inflammatory bowel diseases (IBD) (Crohn's disease and UC). The main criterion for judgement will be the frequency of functional respiratory signs (wheezing, dyspnea, cough, sputum) reported by IBD patients through an adapted self-report questionnaire.

Assessing Cardiovascular Dysfunction Pre- & Post-treatment in Inflammatory Bowel Diseases
Inflammatory Bowel DiseasesThe aim of this study is to compare medical and surgery treatment in IBD patients and healthy controls, by assessing the endothelial and cardiac function and the inflammation status.

Asymptomatic Inflammatory Bowel Disease in Catalonia
Inflammatory Bowel DiseasesAn early treatment of inflammatory bowel disease (IBD) has been proposed to correlate to better outcomes. In Catalonia the screening programme was implemented in all the territory in 2015. The aim of this study is to describe the natural history of the asymptomatic IBD detected during colorectal cancer population screening.

Delayed Diagnostic Time& Inflammatory Bowel Diseased Patients
Inflammatory Bowel DiseasesIntroduction The incidence of inflammatory bowel disease [IBD] is increasing worldwide. Both Crohn's disease [CD] and ulcerative colitis [UC] are therefore becoming an important public health issue[1] The IBD is characterized by chronic intestinal inflammation, which can cause bowel damage and intestinal complications primarily depending on the duration and severity of the inflammation[2] The diagnosis of inflammatory bowel diseases (IBD) is often established following considerable delay due to nonspecific and inconsistent symptoms. In previous western studies, the delayed diagnosis was associated with poor outcome in patients with Crohn's disease (CD).[2] Timely diagnosis is not only important for the patients themselves but has also become a relevant public health issue due to the rising incidence of IBD worldwide[3] Patients and methods Cross sectional observational study will be conducted among 700 patients of Egyptian inflammatory bowel diseased patients for different regions Aim of the study Estimate time delay for diagnosis of Egyptian inflammatory bowel diseased patients compare the delay time for diagnosis of Egyptian inflammatory bowel diseased patients globally

Occupational Insertion and Educational Level of Adult Patients With Pediatric Early Inflammatory...
Crohn DiseaseUlcerative ColitisThe main objective of this project is to assess the occupational insertion of these adult patients with pediatric-onset IBD and to compare it with the general population. The secondary objectives are: to assess the level of education and compare it to that of the general population to assess occupational insertion and the educational level according to: The disease (Crohn's disease, ulcerative colitis or unclassified colitis) sex Age at diagnosis (<or ≥ 10 years) The occurence of surgery, the location of the disease, the treatments undertaken Quality of life Evaluate the patient's feelings about the impact of his illness on occupational insertion and the educational level To describe the quality of life of patients in relation to disease activity and health states (QALY calculation) To assess the responsivness to change of the functional handicap score IBD-DI (n = 200 patients)

Evolution of Lymphocyte Populations Under Biotherapy in Inflammatory Bowel Disease
Inflammatory Bowel DiseaseThis is a monocentric prospective study for the collection of biological samples (blood and biopsies) to be used for in vitro biomarker assay(s) performed to identify predictive markers of response to biological treatments in inflammatory bowel disease (IBD).

Genomic/Epigenomic Biomarkers of Deregulation of Immune System in Inflammatory Bowel Diseases
Crohn DiseaseThe purpose is to search for enterocyte-specific or non-specific molecular signature of post-operating recurrence of Crohn's disease in transcriptome (measurement of gene expression through number of mRNA copies transcribed for each gene) and in methylome. Secondary objectives are to compare expression and methylation profiles according to: treatment response morphological (endoscopic and/or radiological) and clinical post-operating recurrence.

Analysis of Volatile Organic Compounds in the Exhaled Air in Inflammatory Bowel Disease
Volatile Organic CompoundsInflammatory Bowel DiseaseThe availability of noninvasive biomarkers for diagnosis and stratification of inflammatory bowel disease (IBD) courses is lacking. Thus, the aim of this study is to evaluated the accuracy of exhaled breath volatile metabolite analysis on diagnosis and stratification of patients with inflammatory bowel disease.

Association Between Inflammatory Activities and Gap Density
Inflammatory Bowel DiseaseThe study aims to: To determine the relationship between inflammatory activities and epithelial gaps in IBD by CLE and evaluate epithelial gaps healing via dexamethasone treatment. To demonstrated the alteration of local barrier function in IBD using CLE.

Differential EBI2 Expression Upon Allelic Status of the rs9557195 Polymorphism
Inflammatory Bowel DiseasesEBI2 is a risk gene for inflammatory bowel diseases (rs9557195). Patients of the Swiss IBD cohort study have been genotyped for the allelic status of EBI2. The investigators will test the influence of rs9557195 genoty (TT or CC allel), inflammatory activity and current treatment (infliximab vs. vedolizumab) on expression and activity of EBI2 on blood lymphocytes, mRNA expression of EBI2 and UBAC2 (located on the opposite DNA strand of EBI2) and activity of lymphocytes on a migraton assay.
