NCT07550673
This clinical trial aims to evaluate the comparative efficacy and safety of upadacitinib versus infliximab as second-line treatments for acute severe ulcerative colitis, addressing the following key questions: (1) Can upadacitinib as a second-line therapy effectively induce remission in acute severe ulcerative colitis with efficacy non-inferior to infliximab? (2) What adverse reactions may occur with upadacitinib in the treatment of acute severe ulcerative colitis? Researchers will also compare the efficacy of upadacitinib with that of corticosteroids to assess its therapeutic effect. Participants will be assigned to either the upadacitinib group (receiving upadacitinib extended-release tablets 45 mg once daily for 8 weeks, followed by 30 mg once daily) or the infliximab group (receiving an initial dose of 5 mg/kg, with additional doses at week 2, week 6, and every 8 weeks thereafter at the same dose). The treatment duration is 3 months, with outpatient visits for examinations and tests every two weeks. Patients will record their bowel movements and symptoms such as abdominal pain, and undergo colonoscopy, ultrasound examinations, and blood tests at specified time points.

NCT07089771
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.

NCT05739864
In the last decades fecal microbiota transplantation (FMT) has been established as a highly effective option in the treatment of recurrent Clostridioides difficile infection (rCDI), with a success rate of nearly 90%. For this reason, it is recommended by international guidelines as a treatment option for this indication in clinical practice. Recently, a considerable body of evidences, suggest FMT as an effective and safe treatment in patients affected by Ulcerative Colitis (UC). In a recent meta-analysis of 324 subjects with UC, 30.4% of patients achieved both clinical and endoscopic remission after FMT compared to placebo (9.8%, P\<0.00001). However, among the various published trials there is a fair variability in terms of methods and results, which are not comparable to those obtained in the rCDI. Nowadays, one of the most critical factors involved in the effectiveness of FMT in UC patients, is the choice of the donor. In addition, several studies have shown that some donors are associated with a higher clinical response rate than others. This hypothesis has been demonstrated in patients affected by irritable bowel syndrome, in which the use of a super-donor (a healthy person who has the predictive clinical and lifestyle characteristics of a healthy microbiota, and with a microbial profile associated with favorable clinical conditions) resulted in significantly higher clinical efficacy rates than placebo, similar to those obtained in rCDI (89%). Currently, studies that explored the efficacy of the super-donor FMT in UC patients are not yet available. Aim of this study is to investigate the efficacy of super - donor FMT, compared with placebo FMT, in the treatment of UC. The investigators will randomize adult patients with a recent diagnosis of UC to FMT from super - donors or placebo, by colonoscopy (first infusion) and capsules administration. Then, patients will be followed up 2 months after FMT.
NCT05199532
The purpose of this study is to learn more about Eosinophilic Gastrointestinal Disorders (EGIDs). With this registry we hope to find out more about the symptoms that patients have during their treatment, the quality of life they have with the diagnosis, what the disease looks like throughout the different treatment methods, and if there is a connection between EGIDs and connective tissue disorders. The goal of this study is to be able to better understand EGIDs and use information gained from all the information collected on this study for more precise treatments in the future. We want to create a large collection of samples, called a biorepository, to learn the most about EGIDs as possible. When the samples are collected, which will occur at procedures directed by your child's doctor as part of their standard of care, they will be stored for an unlimited amount of time to perform experiments on these samples and to gather information about EGIDs
NCT07472309
The aim of this retrospective observational study is to investigate and compare the real-world effectiveness and safety of upadacitinib when used as first-line exposure versus rescue exposure in patients with acute severe ulcerative colitis (ASUC). The key questions to be addressed are: In patients with ASUC, does upadacitinib administered as first-line induction exposure result in higher rates of colectomy-free survival, clinical remission, and endoscopic healing compared with its use as rescue exposure following failure of conventional or biologic therapies? What are the differences in the incidence, type, and severity of adverse events between these two real-world treatment exposure patterns? The researchers will conduct a retrospective analysis of medical records and electronic health data from patients diagnosed with ASUC who received upadacitinib either as part of routine first-line clinical care or routine rescue clinical care. All treatment decisions were made by treating clinicians per standard of care; the investigator did not assign or modify any therapeutic interventions. Data will be collected during a defined follow-up period to compare the real-world effectiveness and safety profiles of the two treatment exposure strategies.

NCT03724175
The cause of Inflammatory bowel disease (IBD) is unknown, but intestinal bacteria-involved in the production of molecules that impact health-are widely accepted to play a key role. A significant proportion of IBD patients with pouches (surgically created rectums after the diseased colon is removed) continue to have inflammation similar to their previous disease. Only a few microbes are known to have the capability to modify primary bile acids (PBAs) made by the liver to secondary bile acids (SBAs). SBAs are some of the most common metabolites in the colon and play key roles in several diseases. In this study the investigators will investigate if ursodeoxycholic acid (UDCA) may reduce inflammatory markers and improve quality of life (as assessed by validate survey) in those subjects with active antibiotic refractory or antibiotic dependent pouchitis.
NCT05076175

NCT04191655
Inflammatory Bowel Disease (IBD) involving the colon is a known risk for colon cancer. There are two standards-of-care colonoscopy techniques used for screening all patients who suffer from IBD for more than eight years. One method is to obtain random biopsies throughout the colon and the other is by using dye spraying chromo-colonoscopy. This trial aims to study the difference between the two colonoscopy techniques during the era of high definition camera in detecting neoplastic lesions during screening patients with long-standing IBD.
