Active clinical trials for "Inflammatory Bowel Diseases"

The descriptive purpose of this study is to characterize clinical and nonclinical factors of participants with CD, participant flow and visits to other specialists in the hospitals of the healthcare network of the Autonomous Community of Madrid with implementation of electronic medical records. The clinical and nonclinical factors include: demographic and baseline clinical characteristics, lifestyle, relapses, complications, day hospital visits, surgery, presence of complications such as perianal fistulas and complex perianal fistulas. The predictive purpose of this study is to develop a statistical predictive model with the information obtained from the descriptive purpose, in the hospitals of the healthcare network of the Autonomous Community of Madrid, capable of assigning any participant diagnosed with CD a probability of reaching a prototypical clinical condition or a probability of experiencing certain clinical complications.

The purpose of this research study is to understand the relationship between inflammatory bowel disease (IBD) and Glycogen storage disease (GSD)type Ia. GSD type Ib has been established to have an association with IBD with clinical and histologic features that mirror those of Crohn disease. Development of the disease seems to be related to the defect of neutrophil function in individuals with GSD type Ib and subsequent colonic inflammation. In the last decade, it has become a standard for patients with GSD type Ib and gastrointestinal symptoms to be evaluated for IBD. Patients with GSD type Ia were not recognized to have similar gastrointestinal symptoms until recently. The prevalence of IBD is greater in patients with GSD type Ia versus the general population.

Studies over the past two decades have convincingly demonstrated the role of barrier dysfunction in the pathogenesis of inflammatory bowel disease. It previously shown that optical biopsy with probe-based confocal laser endomicroscopy (pCLE) could be used to assess mucosal barrier function. Furthermore, mucosal barrier dysfunction on pCLE was shown to be predictive of disease relapse in adult IBD patients. The purpose of the current study is to determine the predictive value of pCLE findings in pediatric IBD patients.

The purpose of this study is to investigate the vaccination status, knowledge about vaccination, and attitude to vaccination of the Korean patients with inflammatory bowel diseases

The purpose of the study is to develop a validated French version of the IBDQ in a cohort of patients suffering from Inflammatory bowel diseases, namely Crohn's disease and Ulcerative Colitis.

We propose a randomized controlled study to determine the detection rates of neoplasia with high definition colonoscopy alone, high definition dye spraying chromoendoscopy or High definition iSCAN virtual chromoendoscopy in patients with long standing colitis (8 years from diagnosis except primary sclerosing cholangitis when surveillance starts at diagnosis) CD or UC. We hypothesized that these novel endoscopic techniques using High definition colonoscopy with virtual chromoendoscopy -iScan 2 and 3 may be superior to high definition colonoscopy alone and similar to using dye spraying chromoendoscopy for detection of dysplasia and neoplasia in patients with long standing IBD. We will aim to demonstrate if we can avoid dye spraying during the procedure and save expense and considerable time. In addition, we can hope to produce evidence and inform the way in which we perform surveillance colonoscopy especially without large number of multiple random biopsies but only few targeted" smart and intelligent" biopsies using high definition colonoscopy with iSCAN technique as is already the European practice in several centres.

The purpose of this study is to investigate the proportion of use of complementary and alternative medicine (CAM) in patients with inflammatory bowel disease (IBD). In addition, the reason for, and satisfaction with use of CAM.

Cross-sectional study of potential triggers for flares of Crohn's disease or ulcerative colitis.

Both ulcerative colitis and Crohn's colitis are associated with an increased risk of developing colorectal cancer (CRC). Although the increased risk of CRC in colitis patients is well established, several studies show that the risk varies widely between patients, depending on the presence of risk factors. Recently, several of these risk factors were implemented in the updated British guidelines for surveillance which are now used to determine surveillance intervals in our center. The new guideline recommends stratification of patients in a high, medium or low risk group depending on the presence of clinical and endoscopic risk factors and to adjust the surveillance interval accordingly. Although these guidelines provide a first step towards an individualized surveillance regimen, current data regarding risk factors for IBD (inflammatory bowel disease) -associated CRC are solely based on retrospective studies. Prospective data on the phenotype and genotype reliably predicting the risk of CRC is needed to further optimize surveillance in the future. Objectives: To confirm established and identify new predictive factors for colorectal cancer in a prospective cohort of IBD patients undergoing regular surveillance. Dysplasia or colorectal cancer will be the primary outcome. To provide evidence that mucosal healing results in a significant reduction of colorectal dysplasia/neoplasia in IBD patients and that this is associated with 5-ASA (5-aminosalicylic acid) or anti-TNF (tumor necrosis factor) maintenance therapy. Study the expression of several tumor markers in biopsies, blood and faeces at baseline and determine whether expression of these markers can predict dysplasia or colorectal cancer development during follow-up.

The primary objective of this study is to gather stool samples from subjects with inflammatory bowel disease (IBD) to be added to a test set of stool samples that will be utilized to help select molecular markers and determine the optimal sensitivity and specificity values for the Exact IBD-ACRN surveillance test for colorectal cancer (CRC).
