Active clinical trials for "Inflammatory Bowel Diseases"

Crohn's disease(CD),a type of inflammatory bowel disease(IBD), is a chronic intestinal recurrent inflammatory disease involving the entire digestive tract. And Ustekinumab, a monoclonal antibody against the p40 subunit of interleukin-12 and interleukin-23, is a newly targeted drug approved for the treatment of Crohn's disease in recent years.Based on the high-throughput imaging characteristic analysis technique, this study quantitatively analyzed the transmural inflammation of Crohn's disease, and discussed its prognostic value in the treatment of Ustekinumab, and further analyzed the increment of its relative clinical index.

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).

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).

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.

: 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.

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.

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.

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)

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.

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.
