Active clinical trials for "Crohn Disease"

Background Determining disease activity in IBD is sometimes difficult and, to be accurate, requires endoscopy. The serum marker CRP has not proven sufficiently valuable as a marker for IBD specific inflammation. As an alternative, so far fecal calprotectin appears to be more reliable and has shown a certain value as predictive marker. Our preliminary data now show, that the serum concentrations of ficolin-2 are significantly higher in CD patients with a HBI >3. Ficolin-2 is a lectin and acute phase protein produced in the liver and, like MBL, can activate the lectin pathway of complement. Unlike MBL, deficiency for ficolin-2 was not detected in our patient cohort, nor could we find functional deficiencies for ficolin-2 (paper submitted). Study Aims The study is aimed to substantiate the data from our pilot study which shows that ficolin-2 is significantly increased in CD patients during inflammation. Therefore, the study will measure ficolin-2 concentrations in a sufficiently large patient group to obtain enough statistical power and to compare these results with the endoscopic disease score (SES-CD) and CRP and calprotectin values. Statistical analysis of the data will show us if ficolin-2 is a reliable and easy to obtain new marker for active inflammation in CD. Study Design Based on a power analysis 112 CD patients and 112 UC patients need to be analyzed. They will be recruited from Bern, Basel and Lausanne. Only patients with routine endoscopy will be included in the study and will be scored by SES-CD. Blood samples will be collected at the day of endoscopy. Stool sample will be collected within the same week of endoscopy. Calprotectin and CRP concentrations will be determined by routine diagnostics, ficolin-2 concentrations will be determined by ELISA in our laboratory. Finally, all data will be statistically analyzed.

Long-standing ulcerative colitis is associated with an increased cancer risk. Chromoendoscopy with dye spraying can detect subtle abnormalities that are not visible with standard endoscopy. The purpose of this study is to determine if chromoendoscopy with fewer "targeted biopsies" can replace standard colonoscopy with multiple "random" biopsies.

The purpose of this study is to compare MRI enteroclysis with MRI of the small bowel with a per oral 6%mannitol solution.Our hypothesis is that the peroral technique preform the same way as MRI Enteroclysis.

This study aims to test, if a two-week integrative therapy in an internal medicine ward will improve symptoms, disability and quality of life in patients with inflammatory bowel disease or irritable bowel syndrome.a It shall further be tested, if those changes are associated with attitudes and experiences towards complementary and alternative medicine, anxiety, depression and stress perception as well as body awareness and responsiveness.

The PREdiCCt Study: This is a major study that is now being launched. This is the first study of its kind and is specifically directed toward understanding how environmental factors and the gut microorganisms influence IBD flare and recovery. For the PREdiCCt study, the investigators hope to recruit 3100 people in remission from Crohn's disease or ulcerative colitis (illness under control) from 28 inflammatory bowel disease clinics across the UK. The investigators hope to conduct the study in the following stages;- Patients with Crohn's disease, ulcerative colitis or inflammatory bowel disease unclassified (IBDU) in clinical remission (under control) will be approached in gastroenterology clinics across the country and invited to take part in the PREdiCCt study. Alternatively they will express their interest in the study after seeing PREdiCCt promotional leaflets/posters/videos/social media. Participants will attend a clinic visit for routine tests and also to complete several questionnaires with a research nurse. At home over the next week participants will complete detailed questionnaires assessing their environment and diet. Participants will also collect a stool and saliva sample and send this to our laboratories (the investigators have developed easy ways of doing this reliably by post). The stool sample is to analyse the microorganisms in the participant's gut and the saliva is used to analyse their DNA. In addition to this the participants are asked to complete a 4-day weighed food diary. The food diary is sent to the University of Aberdeen for analysis. Investigators will then follow patients' progress over 24 months. They will be asked to complete a short questionnaire every month with a longer questionnaire after 12 months and culminating in a final questionnaire 24 months after their initial clinic visit. If a participant experiences a flare, investigators will collect an additional stool sample; but most importantly investigators will look to see how the environmental and microorganism factors recorded at the beginning differ for those that flare up versus those that don't. What investigators hope to achieve;- Finding out the environmental and dietary factors for patients to avoid because they trigger flare. Finding out behaviours for patients to adopt because they bring about remission. Finding out what the microorganisms that predict flare look like. Gaining information which helps future studies aimed at finding better diets for IBD sufferers. Developing ways of gathering information online from IBD patients about their well-being that doctors can routinely use. The investigators have assembled expert doctors, epidemiologists, microbiologists, nutrition scientists, and bioinformaticians. These experts will use the systems the investigators have put in place to make sure PREdiCCt succeeds. It will yield a lot of new information to help sufferers right away; but the information will also help to kick start many important future studies that will bring us ever closer to a cure for Crohn's disease and ulcerative colitis.

This study will compare healing and surgical outcomes in patients with chronic perianal disease treated with Adipose-derived Stem Cells (ASCs) to outcomes in patients treated in traditional surgical techniques without ASCs. The study will perform retrospective medical record analysis to clinically characterize patients that have undergone these surgical procedures and compare follow-up data and disease status to determine efficacy of treatment with ASCs compared to similar treatments without the use of ASCs. This will help determine overall efficacy of the treatment as well as determine patient characteristics that may predict treatment success. The study will also prospectively recruit patients with perianal disease that are planning to receive treatment with ASCs, and analyze their outcomes in the same way. Medical record review of outcomes in patients with perianal disease that received treatment with ASCs compared to those that did not will determine efficacy of this procedure.

EDUMICILOR is a monocentric prospective pilot study for patients with inflammatory bowel disease (IBD). During the study, patients will participate in an online therapeutic education program. They will first have an appointment with a nurse to establish a personalized educational diagnosis. Then they will participate in the online therapeutic education program for about 6 months (depends on the educational needs, expectations and patient's availabilities). The main objective of this study is to assess the feasibility of an online therapeutic education program for IBD patients.

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.

The aim of this study is to evaluate the evolution and possible factors associated with the persistence of fatigue in patients with quiescent IBD and fatigue included in two previous studies.

The purpose of this study is to collect data about the efficacy of Permacol Paste treatment in perianal Crohn's Disease.
