Predictive Value of pCLE Findings in Pediatric IBD

Inflammatory Bowel Disease

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.

Comparison of Surveillance Colonoscopy Techniques in Patients With IBD

Inflammatory Bowel Disease

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.

Risk Factors for Colorectal Cancer in Patients With Inflammatory Bowel Disease Undergoing Surveillance:...

Inflammatory Bowel DiseaseColorectal Cancer

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.

Confocal Endomicroscopy During Endoscopy

Inflammatory Bowel Disease

The main objective of this study is to determine the role of epithelial cell homeostasis in the pathogenesis of intestinal diseases. Background: Alterations in intestinal barrier function may play a significant role in the pathogenesis of chronic intestinal diseases such as inflammatory bowel disease (IBD). The intestinal epithelium functions as a barrier to the luminal contents, thereby preventing undesirable solutes, micro-organisms and other luminal antigens from entering the body. Confocal endomicroscopy has recently been shown that increased epithelial cell shedding may contribute to increased intestinal permeability, at least locally. In our study, we want to determine the contribution of epithelial cell shedding to intestinal permeability in vivo in patients with inflammatory bowel disease compared to controls. Scope: In inflammatory bowel disease patients and controls (patients undergoing endoscopy for other indications). Methods: We will perform confocal endoscopy during the patient's endoscopic procedure. Procedure: The patient will receive intravenous fluorescein, followed by confocal imaging of the gastrointestinal tissue. The images are captured on the computer. The proposed study will provide important insights into epithelial cell shedding as a contributor to altered intestinal permeability.

MACCS: Multicenter Australian CE in Patients With Suspected Crohn's Disease Study

Inflammatory Bowel Diseases

This is a prospective study aimed to validate the ability of capsule endoscopy to accurately diagnose small bowel Crohn's disease in symptomatic patients who have a non-diagnostic standard workup. Patients will be randomized to undergo capsule endoscopy either one week or five weeks after enrolment. Patients will be followed up for up to 3 months after capsule endoscopy.

The Innate Immune System and Inflammatory Bowel Disease

Ulcerative ColitisCrohn's Disease

The study includes individuals with ulcerative colitis, Crohn's disease and healthy controls. The purpose of this study is to examine the innate immune system (IIS) by exposing peripheral blood monocytes to various ligands relevant for stimulation of the IIS and study the immune response. Colonic mucosal samples are examined to find gene expression patterns which may distinguish the two forms of disease from each other and from healthy controls. The hypothesis is that the innate immune system has responses unique for the disease states, and that the diseases may be differentiated by examination of gene expression patterns in mucosal biopsies.
