Brief summary
Title: The Role of Good Viruses in Inflammatory Bowel Disease Background An imbalance in the bacteria in the gut - called gut dysbiosis - is linked to chronic bowel diseases such as Crohn's disease and ulcerative colitis (IBD). A special and more severe form of IBD, called primary sclerosing cholangitis-associated IBD (PSC-IBD), affects both the gut and the bile ducts, and in serious cases can lead to liver failure. There is currently no cure for IBD. Research suggests that microorganisms in the gut, especially bacteria and viruses called bacteriophages, play an important role in how the disease develops. Treatment with stool from healthy donors, known as fecal microbiota transplantation (FMT), has proven effective against certain infections and has shown promising results in IBD. A newer and possibly safer method is fecal virome transplantation (FVT), where only the virus part (the gut virome) of the stool is used. Bacteriophages can kill harmful bacteria and help restore balance in the gut, but their use is still experimental. Therefore, we aim to develop a new treatment by growing bacteriophages from healthy individuals in the lab and using them to restore a healthy balance of bacteria and viruses in the gut of patients with IBD. Purpose of the study The long-term goal of the study is to improve treatment for IBD by gaining a better understanding of differences in the gut virome between IBD patients and healthy people. We also want to explore whether fermented bacteriophages from donor stool can be developed into a future bacteriophage-based therapy. This will be studied using experimental lab setups and animal models. The study will include 10 healthy stool donors and 30 IBD patients (10 with ulcerative colitis, 10 with Crohn's disease, and 10 with PSC-IBD). The study does not involve any treatments - only the collection of biological samples and access to information about your health from your medical record.
