Inflammatory Bowel Disease (IBD)

The diet is assumed to contribute to many of our present non-communicable diseases. Vegetarian products are instead considered to be health promoting, However, it is not verified that the modern vegetarian and vegan products are healthier than the ones they are meant to replace. Products based on vegetables are nowadays often produced with advanced techniques and can therefore differ substantially from the original vegetables. The epithelium in the gut is protected by a mucus layer that efficiently prevents bacteria to encounter the epithelium and even to translocate into the gut and the blood stream. In several inflammatory conditions such as e.g., inflammatory bowel disease (IBD) the barrier integrity is disrupted, and translocation will occur. Fibers are important for the gut microbiota enabling the production of short chain fatty acids (SCFA) that is necessary as nutrition for the epithelial cells, Fibers also promote the development of mucus. The aim of the present study is to evaluate components in the diet that is claimed to be health promoting even though they sometimes can be a hazard to your health. Both fibers and antinutrients can be found in these dietary regimens. The health effects of these products will be studied by analysis of the gut microbiota and the barrier integrity as markers of the health status. Gut microbiota will be analyzed with next generation sequencing and q-PCR (polymerase chain reaction). Diversity and the occurrence of different species will be determined. The barrier integrity will be estimated by analysis of bacterial DNA in blood and presence of live bacteria. The study consists of two different parts: 1a. 60 health volunteers are divided into two groups. One group consumes ordinary dairy based yogurt and the other a yogurt based on vegan products for four weeks to enable a change in the gut microbiota. At start and after four weeks fecal samples and questionnaires about the general health and gastrointestinal symptoms will be retrieved. It should be noted that the compounds offered can be bought in the ordinary shops. 1. b. The same design as above but with IBD patients instead. Their disease activity will be monitored by scoring sheets and regular blood tests as a part of their regular check-up. 2. a. The same design as in 1a but with comparison between a regular meat-based diet and a diet with vegetarian meat substitutes instead. 2b. The same design as I 2a but with IBD patients. Healthy volunteers will be invited wit advertisements. The IBD patients will be recruited at the out-patient clinic at the Dept of Gastroenterology at Skåne university hospital, Sweden. Before inclusion their disease activity will be monitored. The study is a prospective non-randomized intervention study including both men and women. Each individual will serve as their own control. The meals based on meat substitutes will be composed in cooperation with a dietitian. The estimated amount of yogurt is 200-250 gram/day, and the amount of meat is 150-200 gram/day.

The goal of this Randomised controlled trial is to investigate the effect of exercise on changes in quality of life in in patients with clinical quiescent Inflammatory bowel Disease. The main question it aims to answer * The Relationship Between Moderate-Intensity Exercise and Quality of Life in Patients with clinical quiescent nflammatory Bowel Disease Over a Six-Month Period * To examine the association between the recurrence of clinical symptoms(defined as a Harvey-Bradshaw Index \> 5 for Crohn's disease and a Mayo Ulcerative Colitis Subscore \> 2 for Ulcerative Colitis) and changes in inflammatory markers in blood and stool, comparing patients with clinical quiescent inflammatory bowel disease (IBD) who engage in regular exercise versus those who do not. * To evaluate the relationship between higher levels of physical activity and quality of life, sleep quality, and stress levels in patients with clinical quiescent IBD. * To assess changes in body composition including body mass index (BMI), fat mass, total muscle mass, skeletal muscle mass, and skeletal muscle index between patients who exercise regularly and those who do not. Intervened participants will be encoraged in moderate-intensity exercise for at least 30 minutes per session, three times per week or more, under the supervision and guidance of a sports scientist compared participants who do not receive exercise training or supervision from a sports scientist.

In this study, the investigators will test the ability of the Magnetic Flexible Endoscope (MFE) to travel through the colon of people with Inflammatory Bowel Disease (IBD). The MFE is a device made of ultra-flexible tubing that contains a camera, light, and magnet at the tip. The tip of the tube is about the size of a penny. The magnet inside the tip allows the MFE to be moved through the colon by a second magnet attached to a robotic arm that is outside the body. The purpose of this study is to see how the MFE travels through the colon of IBD patients and if it is tolerable.

This is a Randomized, Double-Blind, Placebo-Controlled, Single and Multiple Ascending Dose Phase I Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of QLS1510 in Healthy participants

The goal of this observational study is to learn about how effective Zymfentra (IFX=dyyb) is when treating patients with Crohn's disease (CD) and ulcerative colitis (UC) Does Zymfentra lead to a reduction in symptoms at intervals throughout one year? Participants being prescribed Zymfentra (IFX-dyyb as part of their regular medical care for CD or UC will answer online survey questions about their bowel habits for 1 year.

This study will evaluate whether a 12-week dietary intervention can improve gut health, inflammation, and quality of life in adults with ulcerative colitis in remission. Participants will be randomly assigned to one of three groups: a Mediterranean diet, a Mediterranean diet combined with time-restricted feeding (eating within an 8-hour window each day), or standard dietary advice. The Mediterranean diet emphasizes fruits, vegetables, whole grains, legumes, nuts, olive oil, and fish, while limiting processed foods and red meat. The main outcome will be changes in short-chain fatty acids in stool samples, which are markers of gut health. Additional outcomes include changes in inflammation markers, gastrointestinal symptoms, and quality of life. The results of this study may help identify effective dietary strategies to support patients with ulcerative colitis.

This is a Phase 2, multicenter, randomized, double-blind placebo-controlled study of DISC-0974 to evaluate safety, tolerability, and efficacy in participants with IBD and anemia of inflammation.

Preventive measures are increasingly coming to the forefront of medicine. Many of these measures can be implemented as early as childhood and adolescence. For instance, the early detection and treatment of cardiovascular risk factors can significantly reduce long-term morbidity and mortality associated with cardiovascular diseases such as heart attack and stroke. For years, there has been discussion in Germany about assessing lipid profiles during childhood and adolescence to enable early intervention in cases of conditions like familial hypercholesterolemia. However, comprehensive screening has not yet been established in either clinical guidelines or routine practice. In other countries, such as Norway, universal screening has been conducted for many years and has already demonstrated both its benefits and cost-effectiveness. In Germany, screening, and subsequent early treatment if needed, is currently limited to a small number of children and adolescents-such as patients with type 1 diabetes mellitus (T1DM)-as part of their routine preventive check-ups. The prevalence of dyslipidemia in T1DM is approximately 15%. Reliable prevalence data are lacking for almost all other chronic conditions affecting children and adolescents (e.g., inflammatory bowel disease, celiac disease, rheumatic diseases, congenital heart defects). Through a pilot project at Jena University Hospital, we aim to screen children and adolescents with chronic conditions who are already at increased cardiovascular risk due to their underlying diseases. The project will record lipid levels, clinical data, family history, and lifestyle factors. The results of this study enable us, on the one hand, to help the individual through early diagnosis and consequent treatment recommendations; on the other hand, the data provide important information regarding the prevalence of hyperlipidemia and other risk factors-such as physical inactivity-within this high-risk cohort.

This study explores whether simple nutrition education can help children and teens with inflammatory bowel disease (IBD) eat fewer ultra-processed foods (UPFs). UPFs include packaged snacks, sugary drinks, and fast food-items that are high in added sugars, fats, and artificial ingredients. Participants will complete online food recalls to measure what they eat and will then receive either nutrition handouts alone or handouts plus a short educational video about UPFs. Researchers will compare changes in UPF intake between the two groups after several weeks and ask families how useful and acceptable they found the materials. The goal is to identify an effective, practical way to support healthier eating habits and long-term gut health in pediatric IBD.

The SHIFT-IBD Study is being conducted at multiple medical centers across Canada to evaluate how well guselkumab (Tremfya) works for people with inflammatory bowel disease (IBD) who haven't responded well enough to ustekinumab. Patients will begin guselkumab based on their doctor's decision. If eligible, they may be invited to participate in the study, which involves monitoring symptoms, test results, and overall health over the course of one year. Guselkumab will be given according to local medical guidelines. Doctors can adjust the treatment as needed, just like in routine care. Researchers believe that switching to guselkumab may be as effective as other advanced treatments. For those who saw some improvement on ustekinumab but not enough, guselkumab may offer better symptom control-without worsening results on medical tests like endoscopy. The goal is to explore better treatment options for people whose IBD has not been well controlled with current therapies.

Acupuncture points or acupoints are fundamental to the practice of acupuncture, yet their scientific basis remains unclear. According to traditional explanations of acupuncture, acupoints can become tender or more sensitive to pressure when there is an underlying disease of the body. Findings from recent basic animal studies support this traditional theory. For example, compared to healthy control animals, models of colitis have shown increased skin temperature, blood flow, and pain sensitivity at specific body regions that correspond to the location of acupoints that are commonly used in acupuncture treatment for colitis. However, little is known about whether these findings apply to humans.

This multicenter retrospective real-world data study will evaluate the treatment pathways and disease burden of adult patients with Crohn's disease (CD) and ulcerative colitis (UC) treated in 5-10 Dutch hospitals between 2018 and 2026. The study will assess: * Treatment sequences, switching patterns, and treatment duration * Prevalence and incidence of extra-intestinal manifestations (EIMs) * Healthcare resource utilization (hospitalizations, outpatient visits, endoscopies, surgery, and length of stay) * Direct healthcare costs * Availability of disease activity biomarkers Using linked administrative, prescription, procedure, and laboratory data, outcomes will be analyzed by age, line of therapy, and clinical characteristics. Special focus will be placed on the impact of EIMs on treatment patterns, healthcare utilization, and costs. The findings will provide real-world evidence on IBD management in the Netherlands and support clinical decision-making, healthcare planning, and future research on treatment optimization and coexisting immune-mediated conditions.

The aim of this study is to identify HRV changes predictive of IBD flares using patient-own wearable devices in a large cohort supplemented by additional data layers including sleep parameters, step count and clinical data extracted from electronic patient files.

The purpose of the study is to compare the effectiveness of recorded gut-directed hypnosis to an educational recording in people with chronic problems in their gastrointestinal (GI) system. Patients who are hospitalized at Stanford Hospital for worsening pain and/or nausea will be considered for enrollment.

Observational, single-center, non-pharmacological, prospective study of adult patients affected by Inflammatory Bowel Disease (IBD) with an ongoing disease exacerbation requiring hospitalization

This Phase 2b randomized, double-blind, placebo-controlled, multicenter trial will evaluate the efficacy and safety of a once-daily oral microbiome-targeted food supplement compared with matching placebo in adults with mild-to-moderate, objectively active ulcerative colitis. The supplement is food-grade and is intended for use either alongside stable standard ulcerative colitis therapy (5-aminosalicylic acid/mesalamine) or in participants not currently on any inflammatory bowel disease therapy. Approximately 162 participants will be enrolled at university hospital centers in Turkey and randomized in a 1:1 ratio to receive either the food supplement or matching placebo for 24 weeks, in addition to their existing background therapy as defined by eligibility. The primary objective is to determine whether the supplement increases the proportion of participants achieving composite clinical-plus-biochemical remission at Week 24. This composite endpoint requires absence of rectal bleeding, improvement in stool frequency, fecal calprotectin ≤250 micrograms/g, and no rescue therapy, prohibited treatment escalation, ulcerative colitis-related hospitalization, colectomy, or discontinuation for lack of efficacy before Week 24. Key secondary endpoints include endoscopic improvement, deep biochemical remission, change in fecal calprotectin, change in partial Mayo score, corticosteroid-free composite remission, change in quality of life, change in C-reactive protein, time to treatment failure, and safety. Exploratory analyses will assess stool microbiome composition, eukaryotic carriage including Blastocystis, and associations between baseline microbiome features and treatment response.

Inflammatory bowel diseases, Crohn's disease and haemorrhagic rectocolitis, are pathologies that progress in flare-ups, impacting on patients' quality of life and functional or even vital prognosis. These inflammatory diseases require the use of immunosuppressive and immunomodulatory treatments, the side-effects of which can be significant, and the limited number of which sometimes puts patients and practitioners in a therapeutic impasse from which surgery is the only way out. It is therefore important to be able to develop new therapeutic approaches, ideally better tolerated, that can control inflammation during relapses. Monocytes are one of the main players in the inflammatory reaction. In the laboratory, we have developed a strategy for the metabolic reprogramming of these cells based on the use of oxygen microbubbles to modulate the inflammatory response of monocytes.

Through a pilot randomized controlled trial (RCT), the aim is to test the clinical impact and feasibility of a AI-enhanced Virtual Reality (VR) Cognitive Behavioral therapy (CBT) program versus distraction VR among patients with inflammatory bowel disease (IBD) and anxiety. It is hypothesized that using VR/AI CBT may reduce anxiety and IBD symptoms, leading to improved overall physical, psychological, and social functioning when compared to distraction VR.

The goal of this clinical trial is to learn if an app designed for diet education can help patients with inflammatory bowel disease (IBD) learn about healthy eating. The main question\[s\] it aims to answer are: * Is the app easy to use? * Is the app useful? Researchers will compare the diet app to see if it is better at teaching patients about a healthy diet than the standard information they may receive from their doctor. Participants will be asked to use the app for one month and answer surveys to see how easy the app is to use and if it leads to healthier eating.

The goal of this clinical trial is to learn what happens to PVT401 when it enters the human body and how it affects the immune system. It will also provide information about the safety of PVT401 after a single dose and after multiple doses. The main questions it aims to answer are: Will participants experience any side effects when taking PVT401? How long does it take PVT401 to leave the body after it is administered? Healthy volunteers will participate in either the single ascending dose (SAD) or multiple ascending dose (MAD) phase. In the SAD phase, participants will: stay in the clinic for two nights, get one dose of PVT401 or a placebo intravenously (through a vein) on Day 1, have blood drawn periodically throughout their stay and be monitored for side effects, and return to the clinic for 3 follow up visits over the four weeks after dosing. In the MAD phase, participants will: stay in the clinic for one night prior to each dose of PVT401 or placebo, and get dosed twice a week for 5 weeks. They will have blood drawn periodically throughout the treatment period and be monitored for side effects, and return to the clinic for 4 follow up visits over the six months after dosing.

People with inflammatory bowel disease (IBD), such as ulcerative colitis or Crohn's disease affecting the colon, have a higher risk of developing colon cancer over time. To catch early signs of cancer, regular colonoscopies are recommended. In this study, the investigators are comparing two advanced methods of examining the colon during these surveillance colonoscopies. One method uses a special dye sprayed inside the colon to highlight abnormal areas (called dye-based chromoendoscopy). The other method uses new technology built into the camera to enhance the view without needing any dye (called virtual chromoendoscopy). Both methods use modern, high-definition equipment. The purpose of this study is to find out if the newer, dye-free method is as good as the traditional dye method at detecting pre-cancerous changes (called dysplasia) in people with IBD. Adults with IBD who are due for a routine surveillance colonoscopy may be invited to take part. Participants will be randomly assigned to one of the two methods. No additional procedures are involved, and only the way the colon is viewed differs. The investigators will also look at how long the procedures take, how many biopsies are needed, any complications, and how patients experience the exam. Participants will be followed over time using national health records to check for long-term outcomes. This research will help doctors better understand which method is most effective and comfortable for patients, and may guide future recommendations for cancer screening in people with IBD.

Primary Sclerosing Cholangitis (PSC) is a rare cholestatic liver disease, commonly associated with inflammatory bowel disease (IBD) The aim of the present trial is to assess the efficacy of fecal microbiota transplantation (FMT) on ALP and bilirubin compared to sham transplantation in addition to ursodeoxycholic acid (UDCA) treatment in PSC patients.

This is a Phase 2, multicenter, platform study in adult participants with IBD (moderately to severely active Crohn's Disease or Ulcerative Colitis). The primary goal of this study is to assess the safety and efficacy of multiple investigational drugs.

Elemental 028 Extra is a nutritionally complete ACBS approved amino acid-based (elemental) feed designed to provide adequate daily amounts of both macronutrients and micronutrients when used as a sole source of nutrition and to support patients with severe impairment of the gastrointestinal tract who may require an elemental diet. An upgraded formulation of Elemental 028 Extra with an increased energy, protein content micronutrient profile has been developed to better meet the nutritional requirements of patients. This series of case-studies aims to evaluate the acceptability, compliance, and gastrointestinal tolerance of the upgraded formulation of Elemental 028 Extra, in 30 adult and paediatric patients (15 powder and 15 liquid), with conditions where there is a severe impairment of the gastrointestinal tract, such as inflammatory bowel disease, short bowel syndrome, intractable malabsorption, allergic disease, and neurodegenerative diseases, and an elemental feed is required. The case study will last 29 days in total, including a 1-day baseline period followed by a 28-day intervention period. The case studies will be conducted across multiple centres in the UK, to meet the UK ACBS and GMS requirements for acceptability studies.

The goal of this clinical trial is to find out whether a synbiotic formula (SGR11) can improve symptoms and health measures in people with inflammatory bowel disease (IBD). The main questions it aims to answer are: * Does SGR11 lead to overall improvement in a participant's condition after 8 weeks, as measured by the Clinical Global Impression-Improvement Scale (CGI I)? * Is SGR11 safe and well tolerated in people with IBD? Participants will: * Take the study synbiotic formula (SGR11) daily for 8 weeks * Complete symptom and quality of life questionnaires * Provide stool samples and, if applicable, blood samples to measure inflammation and gut microbiome changes * Report any side effects that occur during the study
