Active clinical trials for "Inflammatory Bowel Diseases"

Inflammatory bowel diseases (IBD) are chronic inflammatory disorders that can be categorized as ulcerative colitis (UC), Crohn's disease (CD) and indeterminate colitis (IC). Deep remission has been shown to improve disease outcome. There may be a lack of concordance between endoscopic and histologic remission. IBD patients with long standing colitis are at risk of developing dysplasia and colorectal cancer (CRC). However, it can be challenging to diagnose dysplasia in IBD patients during colonoscopy, as dysplasia frequently manifests as non-pedunculated lesions that present with only subtle visible changes or are even invisible due to the surrounding inflammation, scarring, pseudopolyps, or hyperplasia. Although white light endoscopy and chromoendoscopy are the current standard modality of imaging, there is still a gap to be bridged, in terms of improving endoscopic diagnosis of dysplasia and improving concordance of endoscopic and histologic remission. Raman spectroscopy is an inelastic light scattering technique provide specific fingerprints of molecular compositions and structures of biological tissues. It may be able to provide additional diagnostic information over standard endoscopy. A second-generation Raman endoscope system for improving in vivo tissue characterization and diagnosis during colonoscopy has been developed (SPECTRA IMDx system). Preliminary data suggested its utility in the diagnosis of colorectal neoplasia during colonoscopy. There is currently a lack of data concerning the application of this novel technology in the context of IBD. Specifically, whether the spectral signals generated can be used to better classify disease remission, and thus achieve higher concordance with histology when compared to standard endoscopy. It is also unclear whether this technology can be used to differentiate dysplastic mucosa from non-dysplastic mucosal in IBD patients. Hypotheses Raman spectroscopy based artificial intelligence system has the potential to be used to differentiate disease remission from active mucosal inflammation and hence improve concordance between endoscopic and histologic remission, with the potential to decrease the need for random biopsies real-time during colonoscopy. Raman spectroscopy based artificial intelligence system has the potential to differentiate dysplastic mucosa in IBD patients (low grade and high grade dysplasia; colorectal cancer) from non-dysplastic mucosa. real-time during colonoscopy.

Vedolizumab is a medicine that helps to reduce symptoms of IBD and the associated inflammation in the digestive system for participants with ulcerative colitis or Crohn's disease. In this study, participants with ulcerative colitis or Crohn's disease will be treated with vedolizumab according to their clinic's standard practice. Participants will receive vedolizumab as either an infusion or an injection just under the skin (subcutaneous). The main aim of the study is to observe real-world treatment patterns in participants treated with vedolizumab. The study sponsor will not be involved in how participants are treated but will provide instructions on how the clinics will record what happens during the study.

68Ga-FAPI has been developed as a tumor-targeting agent as fibroblast activation protein is overexpressed in cancer-associated fibroblasts and some inflammation,such as inflammatory bowel disease. And it might be more sensitive than FDG in detecting a certain type of inflammations according to our preliminary research. Thus this prospective study is going to investigate whether 68Ga-FAPI PET/CT may be superior for diagnosis, therapy response assessment and follow-up of inflammatory bowel disease than 18F-FDG PET/CT.

The aim of this study is to discover inflammatory changes in the gastrointestinal tract in adult patients with suspicion of a chronic inflammatory bowel disease (IBD) by examining the entire bowel, including the small intestine, by using a video capsule. The study compares the video capsule endoscopy with colonoscopy with the question of inflammation and patient satisfaction with the respective examinations. The study is aimed at participants who present to a gastroenterologist because of their complaints like persistent abdominal pain or diarrhea. An infectious genesis and celiac disease must be ruled out in advance. In addition, the determination of the fecal calprotectin (fCal) is necessary for this study. Fecal calprotectin is a stool marker for the severity of an inflammation of the gastrointestinal tract, an increased fecal calprotectin can be an initial indication for the presence of a chronic inflammatory bowel disease. As mentioned above, participants will be examined in one of two ways: either with an examination of the small and large intestines using video capsule endoscopy in one examination (i.e. ,panintestinal capsule endoscopy', PICE) or a colonoscopy is performed as the standard treatment. Which of the two methods is used will be decided by lot, electronically controlled. Colon cleansing is necessary in preparation for both examinations. The advantage of being assigned to the video capsule group is, in addition to showing the entire intestine in one examination, that no sedation is necessary for this examination. In addition to the examination, participants have to fill out a questionnaire with information about their state of affairs, their well-being and their experience with the examination. After a period of six month the participants will be contact by phone to inquire about their current state of health.

Chronic inflammatory bowel disease (IBD) is associated with an increased risk of colorectal cancer (CRC) in historical cohorts. The pathways of oncogenesis of these CRCs, which are very different clinically from de novo CRCs, are currently unknown. The aim of our work is to identify specific molecular signatures of CRC occurring in the setting of IBD.

Periodontal diseases are highly prevalent inflammatory diseases. It is now well known that they are correlated with numerous systemic diseases as : diabetes, chronic obstructive pulmonary disease, metabolic syndrome or rheumatoid arthritis. Recently, periodontal diseases have been correlated with inflammatory bowel diseases (IBD). IBD include two types, Crohn's disease and Ulcerative Colitis. It could be a significant risk factor for the pathogenesis of periodontal disease. These diseases present common features : a high prevalence worldwide, multifactorial pathogenies with common mechanisms. To date, no study has linked activity of IBD and periodontal diseases. The authors hypotheses that the prevalence of periodontal diseases could be increased in patient presenting an active IBD

Study to compare the detection of neoplastic lesions between chromoendoscopy and NBI

Ocular damage is found in the 3rd rank of extra intestinal manifestations (MEI) Potentially serious functional complications (see uveitis and risk of blindness) requiring rapid management Rare uveitis in the literature (0.5% -3%), study on a large sample to assess their prevalence in patients with IBD at the Nancy CHRU and describe all the ocular manifestations that can be found.

Helicobacter pylori (H. pylori) infection is one of the most common infectious diseases in humans.

This study explores the lived experiences of family planning for women with inflammatory bowel disease (IBD) and their partners during the reproductive stages of pre-conception, pregnancy and the postnatal period through qualitative interviews. Insights from existing literature alongside findings from interviews and focus groups with patients and healthcare providers to develop an intervention to address the issues and support needs as identified by study participants.
