Active clinical trials for "Crohn Disease"

Inflammatory bowel disease (IBD) is a chronic idiopathic inflammatory condition of the intestine, which results in diarrhea, rectal bleeding, urgency, weight loss and abdominal pain. The natural course of IBD is characterized by activity outbreaks and periods of remission. In most cases, relapses in Crohn's disease (CD) and in ulcerative colitis (UC) are unpredictable and despite effective medical treatment, a degree of subclinical inflammation may persist in the bowel wall, contributing to a significant risk of relapse. In IBD, altered fecal microbiota signatures have been consistently reported which included a reduction in biodiversity with lower proportions of Firmicutes and increases in Proteobacteria and Bacteroidetes phylum members. It is however unclear whether changes in microbial profile including diversity and composition can predict disease relapse in IBD. We hypothesize that fecal microbial signatures in conjunction with fecal calprotectin may play a role in predicting relapse in IBD patients.

One aims to devise a method for the screening and differentiation of intestinal tuberculosis and Crohn's Disease. Additionally, one aims to detect and survey multidrug resistant TB.

Study hypothesis - this study will assess the presence of endothelial dysfunction in patients with Crohn's disease before and after 12 weeks treatment of anti TNF α.

The purpose of this study is to assess whether green tea or coffee influence the course and life quality of patients with mild to moderately active Crohn's disease.

The purpose of this study is to analyse effectiveness and safety signals of current treatment strategies in routine practice for patients with pediatric-onset inflammatory bowel disease (PIBD) and to correlate this to their individual risk factors.

Chronic inflammatory diseases (CID) - including inflammatory bowel diseases (Crohn's disease and ulcerative colitis), rheumatic conditions (rheumatoid arthritis, axial spondyloarthritis, psoriatic arthritis), inflammatory skin diseases (psoriasis) and multiple sclerosis are diseases of the immune system that have some shared genetic and environmental predisposing factors, but still little is known on the effects of lifestyle as a prognostic factor on disease risk. This observational study will contribute to preexisting research on lifestyle factors by identifying diet factors associated with risk of developing CID, using prospective register data. The study will use data from all of the 57,053 participants in the Danish cohort "Diet, Health and Cancer (DHC)" together with registry data. Blood samples, anthropometric measures and questionnaire data on diet and lifestyle were collected at the DHC study entry. The National Patient Registry (NPR) will be used to obtain to identify patients with CID during follow-up. Follow-up information on death and immigration will be collected in March 2018 from the Danish Civil Registration Register. The outcome CID is defined as at least one of the following CIDs: Crohn's disease, ulcerative colitis, psoriasis/psoriatic arthritis, rheumatoid arthritis/ankylosing arthritis, or multiple sclerosis, during the follow-up period from 1993 to March 2018. The primary hypothesis is that "the risk of CID will be significantly higher among those with a low fibre/high red and processed meat intake compared to those with a high fibre/low red and processed meat intake." Based on previous research on a shared etiology in CIDs a second hypothesis is that "the postulated causality between low fibre/high red and processed meat intake and risk of developing CID is applicable for each of the CID-diagnoses." The core study is an open register-based cohort study. The study does not need approval from the local Ethics committee or Institutional Review Board by Danish law. The study was approved by the Danish Data Protection Agency (2012-58-0018) Study findings will be disseminated through peer-reviewed journals, patient associations and presentations at international conferences.

In this study we would like to clarify the effect of long lasting Crohn's Disease on motility of the gastrointestinal system in patient and the effect regarding sleep disturbances. This will be done with a newly developed 3D-Motility-and-Transit-detector (Motilis Medica, Schweiz) and the well known polysomnographic equipment. Our hypothesises are: Patients with ileocoecal and/or colonic CD in remission and gastrointestinal symptoms have abnormal colonic transit (primary endpoint). Patients with ileocoecal and/or colonic CD in remission and gastrointestinal symptoms have abnormal gastric emptying and small intestinal transit (secondary endpoints). Total and segmental transit times found in patients with CD will be compared with corresponding transit times in healthy volunteers found in a previous study. Patients with ileocoecal and/or colonic CD in remission have abnormal sleep patterns. Nocturnal basic colonic activity, have changed in patients with ileocoecal and/or colonic CD in remission and sleep disturbances.

To develop a cost-effective, individualised anti-TNF treatment strategy for patients with Crohn's disease which maximizes benefit and minimises harm. The primary objective of this study is to investigate the mechanisms that underlie primary non-response (PNR), loss of response (LOR) and adverse drug reactions (ADRs) to anti-TNF drugs in patients with active luminal Crohn's disease.

Laparoscopy combined with an enhanced recovery pathway versus laparoscopy combined with a traditional recovery pathway after ileocolon resection for Crohn's Disease.

Retrospective multicentre study. All patients with a diagnosis of Crohn's disease (CD) and operated for colorectal cancer (CRC) between 01/01/2010 and 01/01/2020 will be included in the dataset. Data will include preoperative, intraoperative and postoperative variables, with long term follow up when feasible. The study will focus on a comparison between patients treated with total proctocolectomy (TPC) and patients treated with subtotal colectomy (STC) or segmental resection (SR). Primary endpoints will be oncologic outcomes, postoperative morbidity and mortality. Secondary endpoints include quality of life (QoL).
