Active clinical trials for "Intestinal Diseases"

This is a prospective, non-interventional registry and biorepository for patients with IBD. Longitudinal follow-up data is collected from both patients and their treating gastroenterologist during routine clinical encounters. The biorepository will consist of prospective collection of blood samples, tissue samples, and fecal samples for research purposes, while the participants are undergoing a clinically-indicated procedure (i.e. venipuncture for routine tests, IV catheter placement, and/or endoscopy). Participants may choose to provide any or all of the aforementioned information and/or samples.

Non-IgE-mediated gastrointestinal food allergies (non-IgE-GIFA) are an evolving web of clinical conditions characterized by subacute and/or chronic symptoms and include food protein-induced enterocolitis syndrome (FPIES), food protein-induced enteropathy (FPE), food protein-induced allergic proctocolitis (FPIAP), and food protein-induced allergic dysmotility disorders (gastroesophageal reflux disease (GERD), colic and constipation) (FPIMD). Despite the prevalence and clinical impact of these conditions, the pathogenesis as well as the natural history and the best management of these disorders are still poorly defined. These limitations could be responsible for diagnostic delays and errors, and suboptimal clinical management. We aim to evaluate clinical features, natural course and pathophysiology of non-IgE-GIFA in the pediatric age.

Rates of inflammatory bowel disease (IBD) are increasing rapidly in children and young people, and targets for management are becoming more demanding, with better control of disease to prevent complications, cancers and surgeries. This project "Non-Invasive Monitoring Through Bowel Ultrasound in Paediatric Inflammatory Bowel Disease" or NIMBUS study will aim to explore the possibility of using ultrasound to examine inflammation in this group. Monitoring inflammation in this population currently is done with regular endoscopy (camera tests) and/ or MRI enterography scans which are invasive, can be uncomfortable, expensive and may have long waiting lists. These studies also require bowel prep, in the form of laxative medicines which can be distressing and cause time off from school. Direct visualisation through ultrasound could allow better monitoring of disease, and is quick, accurate, non-invasive and relatively low-cost. This could also allow for more appropriate medication use and a decrease in over/under use of medicines. This study will aim to recruit 50 children and young people with inflammatory bowel disease. Each child will have an ultrasound scan after enrolment and the investigators will use the information from these scans, as well as routine blood tests (already taken in normal care) and follow up medical information to explore the use of ultrasound in this group. The investigating team will aim to contribute to the global discussion around this topic and if results are positive will aim to improve monitoring for this population managed at the Noah's Ark Children's Hospital for Wales.

An international, multicenter, non-interventional, prospective, post-authorization, descriptive, non-PASS, study.

Patients with Inflammatory Bowel Disease (IBD) have higher rates of sexual dysfunction than the general population. We offer an educational program on IBD including a specific discussion on intimacy and sexuality for IBD patients. Our objective is to investigate the benefit of this intervention on sexual function in patients with IBD.

The aim of this project is to start a biological and clinical collection of patients presenting systemic autoimmune disease. This collection will provide appropriate biological samples to identify new biomarkers and to be accessible to the medical, scientific and industrial communities for the identification of new therapeutic strategies

The investigators propose an observational study including patients with inflammatory bowel disease under biological therapy with anti-TNF, anti-integrin α₄β₇ or anti-interleukin 12-23 (Ustekinumab), followed by an external Gastroenterology consultation at Centro Hospitalar Tondela-Viseu.

To develop and train a convolutional neural network to detect and characterize disease severity of inflammatory bowel disease during endoscopy

Inflammatory bowel disease (IBD) is a chronic inflammatory condition for gastrointestinal tract. There have been numerous studies to reveal dysbiosis of fecal/mucosal microbiome composition in IBD patients but actual trend of dysbiosis is strikingly different among patient's ethnicity. In this background, the investigators have composed a prospective cohort of Korean IBD patients in a large academic referral IBD center. Using an integrated multi-omics bioinformatic analysis, the investigators aim to explore gut microbial signatures along with distinct clinical/genetic features, and their potential interplay in patients with IBD.
