Active clinical trials for "Intestinal Diseases"

To construct a standardized stepped nutritional treatment process for inpatients with inflammatory bowel disease, including nutritional risk screening and assessment, standardized nutritional treatment implementation, therapeutic effect follow-up and monitoring, family nutritional treatment follow-up, etc.

The purpose of this study is to evaluate the effect and safety of pectin and fecal microbiota transplantation on patients with inflammatory bowel disease. The investigators hypothesize that patients who take pectin can promote the migration of probiotics in intestine engraftment, reduce pathogenic agents'adhesion to intestinal mucosa, cut down the inflammation, and to maintain intestinal flora diversity and steady state in a long time.

The investigators hypothesised that a video based patient education will help patients understand the process of colon cleansing prior to a colonoscopy procedure and hence will result in clean colons that will may help physician perform a better quality examination.

There are many limitations in the current treatments of Inflammatory bowel disease (IBD). Now the investigators realized that the intestinal microecological is closely associated with the development of IBD. So the standardized fecal microbiota transplantation is considered to be simple but effective emerging therapies for the treatment of IBD. In this project the investigators intend to carry out a single-center, randomized, single-blind clinical intervention study. The investigators will recruit 40 patients with IBD (20 cases of Ulcerative Colitis and 20 cases of Crohn's disease) in China. The patients will be randomly divided into 2 groups, one group will be given treatment of standardized fecal microbiota transplantation, the other will be simply treated with mesalazine, followed up for at least 1 year. The investigators propose to determine the efficiency, durability and safety of Standardized Fecal Microbiota Transplantation for IBD treatment.

This study is a randomized controlled study conducted at five tertiary university hospitals. Patients who are 20-80 years old, diagnosed as having Inflammatory Bowel Disease(IBD) and who are planned to start thiopurines for the first time for the treatment of IBD are enrolled. Patients are assigned to the genotyping group or to the non-genotyping group. The patients who carry any heterozygotic variant among the three genes receive 50 mg azathioprine (AZA) or 25 mg of 6-mercaptopurine, while those who have any homozygotic variant are recommended to take other alternative drugs. The patients who do not carry any genetic variant or are assigned in non-genotyping group receive the standard dose of thiopurines based on the conventional approach. Patients in the non-genotyping group receive the standard dose of thiopurines based on the conventional approach.

Given the current Covid-19 pandemic alongside the lack of evidence on aerosolization during upper endoscopy the investigators are conducting a randomized controlled trial seeking to assess both the level of aerosolization that occurs during these procedures along with determining if utilization of an endoscopic patient face-masks reduces the level of aerosolized particles. The protocol includes the use of a commercially available particle counter the investigators are employing for the measurement of aerosols before, during, and after anesthesia assisted upper endoscopic procedures. The investigators are recruiting patients undergoing these procedures with a target of 30 patients undergoing endoscopy without a facemask and 30 patients undergoing endoscopy with one.

This study uses a comparative method to evaluate the performance of the NaviCam SB capsule endoscope system in comparison to the PillCam SB3 capsule system for the diagnosis of small bowel diseases.

Although the precise etiology of inflammatory bowel disease (IBD) is still unknown, over the last decade active research allowed to gain more precise insights in the pathophysiology of IBD indicating that the chronic inflammation of the intestinal mucosa is directed against the microbiota of the gut in particularly susceptible individuals. Genetic studies and more recently genome-wide association studies (GWAS) have allowed to identify over 70 susceptibility genes which confer an increased risk of developing IBD. In the last years the attention of researchers has shifted to the identification of the early immunological changes that occur already at a preclinical stage of the disease, trying also at identifying the disease before it shows itself. Recently, the ability of a combination of serological markers in predicting the development of IBD has been demonstrated in adults. However, there are no studies evaluating a cohort of children at high risk for the disease, in whom the first immunological changes underlying the development of IBD could be studied, including a combination of genetic, serological, fecal and clinical markers. The purpose of this study is to evaluate in a population genetically well-characterized, as siblings and twins of patients affected with IBD, early genetic, serologic, fecal and clinical markers of disease, which may be present even years before developing the disease. The identification of these markers in predisposed individuals could help to implement strategies for prevention or early treatment to modify the natural history of IBD.

To evaluate the performance of PillCam COLON 2 in regards to detection of patients with polyps where colonoscopy is considered as the gold standard reference.

In the study the investigators aim to test whether transcranial direct current stimulation (tDCS)-induced pain reduction is in association with functional changes in the brain measured with functional magnetic resonance imaging (fMRI) in patients with chronic inflammatory bowel diseases (IBD). Hypothesis: Transcranial direct current stimulation can reduce the perception of pain in patients with chronic inflammatory bowel diseases, which is in association with changes in the brain measured via fMRI.
