Filter by:People with inflammatory bowel diseases (IBD) can be at higher risk of developing abnormal areas in their bowel. These abnormal areas can be due to active inflammation, healed inflammation, polyps or pre-cancerous changes ("dysplasia"). It is for this reason that people with IBD are offered periodic surveillance colonoscopy procedures to identify, characterize and where necessary remove abnormal areas or lesions from the bowel. These can be difficult to characterize correctly, which is important to make the correct endoscopic diagnosis and management plan. Technical advancements in endoscopy mean that more tools are available to identify and characterize these lesions in real time during colonoscopy. Specialists regularly performing gastrointestinal endoscopy and colonoscopy ("endoscopists") will often receive special training, both during their initial postgraduate training and through continuous professional development programs. This study aims to evaluate whether an online training platform can improve the ability of endoscopists to characterize dysplasia in IBD. The goal is to support improved decision-making during IBD surveillance, reporting of dysplastic lesions, and ultimately the care and outcomes of people with IBD.
PURPOSE: The main purpose is to explore clinical efficacy and safety associated with capsule FMT (cFMT) performed in newly diagnosed, untreated patients with rheumatic and gastrointestinal chronic inflammatory diseases (CIDs). DESIGN AND METHODS: In this 1:1 double-blind, placebo-controlled, randomised, 12-month exploratory trial, 200 patients with at least one of 6 different diagnoses of CIDs fulfilling the study criteria will be enrolled at time of diagnosis. The patient groups are: rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PsA), pulmonary sarcoidosis (PSar), Crohn's disease (CD), and ulcerative colitis (UC). The primary endpoint is change from baseline to eight weeks in the physical component summary (PCS) of the short form health survey (SF-36). Key secondary clinical endpoints will be evaluated at 8 weeks. Other secondary clinical endpoints will be evaluated at 52 weeks and reported in secondary papers. The baseline visit will be performed as quickly as possible after the patient's informed consent has been obtained to ensure no unnecessary treatment delay. Stratified by CID diagnosis, patients will be randomised (1:1) to either placebo or single-donor cFMT processed from stool provided to the hospital from anonymous-to-the-patient healthy donors. The experimental intervention FMT/placebo will be repeated once weekly the first month (i.e., each patient will receive a total of four treatments). In addition, all participants will concomitantly be offered the national guideline first-line anti-inflammatory treatment following the baseline visit. At baseline, 8 weeks, 26 weeks, and 52 weeks a thorough clinical examination will be conducted and all relevant clinical scores for each disease entity will be registered. Patient-reported-outcomes including SF-36 and disease specific questionnaires will be collected at week 1, 2, 3, 4, 8 (primary endpoint evaluation), 26 and 52. Adverse events will be monitored through out the trial.
New types of biologics have brought advantages in therapy strategies for Crohn's disease. However, clinical data evaluating their efficacy and adverse in China is lacking. We aimed to evaluate the short-term and long-term therapeutic effect as well as drug adverse of Ustekinumab (UST) and Vedolizumab (VED). Besides, we aim to figure out the independent factors predicting the effectiveness of new biologics. Relations between drug exposure (trough concentration and antibody concentration) and therapeutic efficacy are study in-depth by this retrospective observational study.
Inflammatory bowel diseases are chronic and progressive entities, triggered by exposure to environmental factors in individuals with a genetic background. One of the most common environmental factors is the type of diet which is a key influencer on pathogenesis. Nutrients alter the intestinal microbiota, thus changing the intestinal permeability. The Western-type diet encompasses sugar, fat, and protein-rich products that have some deleterious effects on the intestinal microbiome compared to the plant-based Mediterranean-type diet. Based on this fact, diet-based therapeutic efforts have been used extensively in pediatric Crohn's disease patients and there is strong evidence that exclusive enteral nutrition (EEN) is as effective as corticosteroids to induce both clinical and endoscopic remission but this treatment strategy is underutilized in adults.
If subjects voluntarily consent to participation in the study, those who are finally determined to be eligible for the study after whether all of the inclusion criteria and none of the exclusion criteria are met is checked will receive the study drug. Efficacy and safety will be evaluated at baseline, baseline, 2 weeks, 6 weeks, 14 weeks, 22 weeks, 30 weeks, 38 weeks, 46 weeks, and 54 weeks.
Patients with Crohn's disease generally have nutritional risks and malnutrition. The investigators will conduct a multicenter cross-sectional study to discover nutritional status and body composition of Chinese adult patients with CD.
This study will evaluate if the Groningen Anti-Inflammatory Diet and the ileocolonic delivery of vitamin B2, B3 and C can positively influence the course of Crohn's disease and can positively alter the gut microbiome of Crohn's disease patients as well as healthy volunteers.
The inflammatory bowel diseases (IBDs), ulcerative colitis (UC) and Crohn's disease (CD), are characterized by lifelong relapsing-remitting gastrointestinal inflammation, with symptoms of abdominal pain, diarrhea, and rectal bleeding during active disease. Medical therapy reduces intestinal inflammation and ameliorates symptoms. Clinical remission is defined when symptoms are resolved. In these periods, patients are able to perform daily activities more freely and lead a normal lifestyle. Biochemical remission (normalization of CRP and fecal Calprotectin) and endoscopic remission (no visual signs of inflammation of the mucosa in endoscopy) are the goals of IBD treatment. Unfortunately, 30-40% of patients will relapse during 6 months from achieving remission. Risk factors for disease exacerbation are still unknown, and no guidelines exist as to the prevention of relapse and maintenance of remission in IBD patients. In addition to the above, sleep disturbances and disturbances in the circadian rhythm can be a potential cause of flare-up. Sleep disorders cause changes in immune function, which later affect the course of the disease in IBD. This back affects the sleep pattern, so that a cycle is created, which may perpetuate the inflammation. The interactions between sleep and inflammation are complex. An effective immune system affects sleep, and sleep disorders affect the functioning of the immune system. Furthermore, changes in the biological clock and sleep deprivation have been directly shown to worsen ulcerative colitis in laboratory animals. In people with sleep disorders, high levels of inflammation were found. However, it is difficult to dissect the cause and effect for these associations, given their complex interactions. Therefore we are planning to conduct a prospective study to assess variety of factors that might be associated with the activity of IBD.
The purpose of this study is to characterize which patients with Crohn's disease are likely to respond to standard of care to vedolizumab therapy.
The purpose of the study is to understand the diet patterns, preferences, and impact of diet on daily living in our patients with IBD in Central Texas.
