Filter by:This study offers a questionnaire to patients with Crohn's disease in order to assess their physical activity and / or sport as well as their eating habits in order to assess the impact of these lifestyle habits on activity and the symptoms of the disease.
Inflammatory bowel diseases (IBD) are among the most common chronic illnesses diagnosed in childhood. Moving from the pediatric to the adult health care is a crucial phase, which can greatly affect adolescents' quality of life. According to the latest international guidelines, based in particular on expert opinions, the implementation of joint visits (involving both pediatric and adult gastroenterologists) are highly recommended during the transition period. This trial aims to prove the beneficial effect of the joint visits.
The study is 3 arms observational study with no intervention that aims to understand the link between Crohn's disease, microbiome and diet in children. 150 children newly diagnosed with Crohn's disease will participate in the study and their data will be used to create an algorithm about their microbiome, disease, diet, etc. 100 other children newly diagnosed will participate in the study and their data will be use to validate the algorithm. The investigators will be recruiting 50 healthy participants: 20 that are undergoing an endoscopy for abdominal pain and 30 that comes to the physician for different reasons. After parental consent, the participants will receive an explanation of the study and sign a consent form for colonoscopy. Before colonoscopy, participants will bring fecal samples, give blood samples, biopsies and biopsy brushes (superficial scraping of the tissue) will be taken during the operation. These samples will be retained until further consent is obtained for further study. After receiving the results of the colonoscopy, children who have been diagnosed with Crohn's disease will be offered to participate in the second part of the study, they will receive an explanation about the app, collection of fecal samples at home, diet logs and anthropometric measurements, demographic information, medical and family history will be registered. During the first 3 months: the participants will be asked to log data in the app and collect fecal samples at home. They will be asked to come for a follow up visit where anthropomorphic measurements and blood samples will be taken. Participants will be asked to log in every day to report in the app daily activity and food intake throughout the study period. Each week, the research coordinator will call on participants to make sure the app is correctly filled in, collect the stool samples correctly and answer questions. During the entire study participants will collect fecal samples, every first week of the month participants will enter information in the app. For children who have not been diagnosed with Crohn's disease by the colonoscopy, or children who visit the institute for reasons other than inflammatory bowel disease without a clear finding will participate in the study control group. If consent is given, fecal samples will be collected at the entrance of the study and after one year, blood samples, a food questionnaire and anthropometric indices, demographic information, medical and family history will be completed.
Aims:Prospectively observe the effects of Caltrate supplementation on the chronic course of Crohn's disease patients, analyze whether the effect of Caltrate on CD patients is affected by factors such as disease site, disease activity, treatment, etc.Provide a certain theoretical basis for "precision treatment" for CD patients in the future. Design：It is a prospective cohort study. Investigators include a total of 60 participants with CD according to the inclusion and exclusion criteria, and divide them into two groups to assess their initial disease activity and detect related indicators. At the same time，Investigators detect the Vitamin D Gene gene polymorphisms in all participants.One group is given Caltrate 0.6g per day orally, and the control group do not intervene. After 12 months, re-evaluate the disease activity and retest the relevant indicators, and use statistical methods to analyze whether Caltrate supplementation treatment can increase the serum 25 (OH) D level of CD participants, improve the condition of CD participants,relationship with Vitamin D Gene Polymorphism，and analyze the effect of Caltrate on participants with CD is affected by factors such as disease site, disease activity, and treatment.
Crohn's disease (CD) is a lifelong condition affecting the small and/or large bowel, causing diarrhoea, abdominal pain and weight loss. Patients with CD receive two tests to assess if the patients' CD is active, namely ileo-colonoscopy (camera examination of the large bowel, IC) and a scan of the small bowel (MRE). Together, these tests help determine if the patients' symptoms are due to CD, which is important as the medication to heal the bowel is strong. But, these investigations are uncomfortable, embarrassing, time-consuming and involve hospital visits to two separate departments. A new test involves swallowing a miniature camera, the size of a large vitamin pill (PillCam™ Crohn's (PCC)) that video-records the lining of the small and large bowel. Images are sent to a recorder worn over the tummy. The investigators aim to find out if the PCC capsule delivers a single test that is comparable to current tests (IC+MRE) for patients with CD. 125 patients with CD referred for IC+MRE will be recruited from 3 NHS hospitals. Each patient will undergo all three tests (IC+MRE and PCC). As there is a small risk of the capsule getting stuck (up to 3 in 100 patients), all patients will have a "dummy" capsule to check that the "real" capsule can travel safely through the bowel. If successful (checked with a handheld scanner and CT scan if required), patients proceed to PCC. Patients will receive bowel preparation (a drink to clean the bowel) prior to IC and PCC. The investigators will compare the findings of all three tests. The investigators will interview patients to find out their experiences to inform the way the test is introduced into practice. When consulted, local patients with CD felt the research question is extremely important and all preferred having one non-invasive test over two invasive and uncomfortable tests.
Crohn's disease increases the risk of poor musculoskeletal health, as the inflammatory disease process directly inhibits regulatory pathways involved in bone and muscle formation and maintenance. The negative effects of disease on muscle-bone health are compounded by poor nutritional status, vitamin d deficiency, prolonged exposure to glucocorticoid therapy, and reduced physical activity. Modern, steroid sparing therapies are successful at inducing clinical remission in terms of inflammation, however they have limited effect in remedying observed muscle-bone deficits. Subsequently, patients with Crohn's disease are at increased lifelong risk of pathological fractures and osteoporosis. Novel adjunctive therapies are therefore required to complement pharmacological treatments and target muscle-bone deficits, which are responsible for significant disease burden in Crohn's. High-impact exercise may be a useful additional therapy for patients with Crohn's disease, as the mechanical strains produced during this type of exercise, through large magnitude muscular contractions and ground reaction forces, can promote bone formation and gains in muscle mass. There have been no previous studies assessing the effects of high impact exercise in Crohn's disease, so it is unknown if this type of exercise is safe and feasible in this population. The aim of this study is to assess the feasibility of high-impact exercise for improving markers of bone and muscle health in adults with Crohn's disease, and compare the effects of exercise with a group of healthy age and sex matched controls.
Aims: The main aim of this study is to access the predictive value of Treg and Breg for the clinical effect of Infliximab in the treatment through analyzing the relationship between Breg and Treg and the efficacy of Infliximab. Design: It is a prospective, observational study. In the treatment group, 32 patients with Crohn's disease (CD) about to start Infliximab-treatment are recruited. They have blood samples drawn at week 0 and 14 of Infliximab treatment. 33 healthy individuals serve as a control group. Controls are only investigated once. All treatment and follow-up are according to national guidelines. The frequencies of Treg and Breg are investigated using flow cytometry. Subjects data are extracted from various registries.
Time-restricted feeding (TRF) is a dietary regimen involving the consumption of food and liquids within a defined time window with or without additional restriction on dietary composition. TRF has been associated with improvements in inflammation, host metabolism, autophagy, gut microbial composition, and gut permeability. Crohn's disease is an inflammatory bowel disease of unknown etiology that likely results from a combination of genetic and environmental factors. This proposed study will test the hypothesis that a time-restricted feeding regimen will improve clinical outcomes and favorably influence the gut microbiome in patients with active Crohn's disease. If time-restricted fasting proves beneficial to this patient population then it will pave the way for larger, prospective studies and clinical trials.
The study is looking at the role of the mesentery in disease recurrence for ileocolic Crohn's disease. It is a prospective study that has been designed to perform extended mesenteric excision on patients undergoing their first ileocolic resection for Crohn's disease. Endoscopic recurrence will be monitored with the hypothesis that patients receiving extended mesenteric ileocolic resection will have reduced endoscopic recurrence at 6 months after resection. (limited mesenteric resection).
The purpose of this study is to determine the safety and maximum effective dose (MED) of Interleukin-2 in subjects with moderate-to-severe crohn's disease.
