Active clinical trials for "Inflammatory Bowel Diseases"

Aims: Prospective evaluation of patients with a suspicion or diagnosis of Inflammatory bowel disease (IBD) to evaluate osophageal motility before and during therapy Material and methods: The investigators prospectively perform manometry in patients with or with symptoms consistent with IBD. The investigators evaluate esophageal motility with high resolution manometry before, during and after IBD therapy. Clinical data are also collected to find possible correlations. The study do not modify the planned IBD therapy, but observe motility findings.

In this study the investigators aim to evaluate the ability of i-scan OE together with magnification endoscopy to detect and assess microscopic inflammation in patients with inflammator bowel diseases (IBD).

assessment of inflammatory bowel disease patients in activity and remission by abdominal ultrasound examine non-invasive and in physiological condition by measuring the colon wall thickness in diagnosis and follow up the patient also including extra intestinal features such as the splanchnic vessels,mesentery and lymph nodes . Doppler u.s can evaluate bowel wall vascularity In activity and remission . peripheral hemogram in relationship to activity inflammatory bowel disease asses anemia ,increase monocyte and decrease mean platelet volume( MPV) . also,the investigator will evaluate the outcome of different lines of treatment traditional and biologic therapy (response to treatment,times of activity and complications)

In this study, the investigators propose to use mucosal impedance (MI), a minimally invasive technology, to detect mucosal damage (i.e. barrier dysfunction) based on mucosal conductivity changes in the colonic epithelium.

: Inflammatory bowel diseases (IBD), such as Crohn's disease (CD) and ulcerative colitis (UC) need long term treatments which can conflict with a desire of pregnancy in women. Uncontrolled IBD increases the risk of poor pregnancy outcomes [1]. Antitumor Necrosis Factor α (antiTNFα) are commonly used, off-label, in pregnancy but with the risk of treatment-related complications. Existing recommendations on the use of antiTNFα during pregnancy are conflicting and only rely on expert opinions. This study was aimed to assess appropriateness and risk to benefit ratio of antiTNFα treatment during pregnancy in women with IBD, for both the mother and the baby until the end of the first year.

Ulcerative colitis (UC) belongs to the group of inflammatory bowel disease (IBD) and is characterized by a chronic relapsing disease course. As uncontrolled intestinal inflammation can lead to severe disease complications, treatment of UC has evolved from sole treatment of symptoms up to histological remission which is marked by the absence of histological inflammation. To correctly assess and quantify the degree of histological inflammation in IBD patients remains difficult. Digital holographic microscopy (DHM) is a new imaging technique belonging to quantitative phase contrast imaging. It is based on the detection of optical path-length delays in a stain-free manner, thereby providing a refractive index which directly correlates to tissue density. This study aims to evaluate the role of DHM for quantifying the degree of histological inflammation in endoscopically acquired biopsies of UC patients in a prospective clinical trial. From 28 UC patients, the investigators will obtain endoscopically acquired colonic biopsies. The investigators will assess the degree of inflammation in these biopsies using DHM and in addition to this an experienced histopathologist will determine the degree of inflammation in these biopsies using a histological scoring system (Nancy-Score = goldstandard). Finally, the investigators will directly correlate the results from DHM analysis to the histological analysis using the Nancy-Score.

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.

This observational study will evaluate the social cost and quality of life of participants who have had Crohn's Disease for at least 6 months and have active disease despite drug therapy. Participants are followed for a total of 18 months.

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 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.
