Active clinical trials for "Intestinal Diseases"

This study is to explore the role the sleep/wake cycle (Circadian Rhythm) has on Inflammatory Bowel Disease. Participants will be asked to attend two clinic visits 14 days apart. Participants will complete a packet of questionnaires regarding their health and sleep habits. Over the 14 days between visits participants will be asked to wear a wrist actigraphy device that will measure their sleep-wake activity along with filling in a sleep diary. During the visits, participants will have a physical exam on visit 1 and on visit 2 participants will be asked to give blood, stool, and urine samples. Additionally, participants may also give sigmoid tissue samples during an optional unprepped limited flexible sigmoidoscopy procedure.

Retrospective observational study in which the efficacy of infliximab is studied in patients with inflammatory bowel disease and its subcutaneous levels are monitored.

Performance of diagnostic or therapeutic endoscopic procedures in inflammatory bowel disease (IBD) patients can be challenging during a viral pandemic; the main concerns being the safety and protection of patients and health care providers (HCP). The aim of this study is to identify endoscopic practice patterns and outcomes of IBD and coronavirus disease 19 (COVID-19) with a worldwide survey of HCP.

The prevalence of hepatitis C virus infection (HCV) in patients with inflammatory bowel disease (IBD) ranges from 1-6%. Direct-acting antivirals (DAAs), with cure rates >90%, represent a radical change from interferon-based therapies. The ECCO (European Crohn's and Colitis Organisation) guidelines (Kucharzik T, Ellul P, Greuter T, et al. ECCO Guidelines on the Prevention, Diagnosis, and Management of Infections in Inflammatory Bowel Disease. J Crohn's Colitis. 2021;15(6):879-913) warns about the risk of IBD reactivation due to the effect of DAAs, but HCV management in this situation is uncertain given the lack of evidence. The project is proposed as the largest retrospective multicenter descriptive study carried out to evaluate the use of DAAs for HCV eradication in patients with IBD. The Eneida database (Zabana Y, Panés J, Nos P, et al. The ENEIDA registry (Nationwide study on genetic and environmental determinants of inflammatory bowel disease) by GETECCU: Design, monitoring, and functions. Gastroenterol y Hepatol. 2020;43(9):551-8.) of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) is an adequate registry to identify patients with HCV infection. The serological status of the infection is frequently recorded in the ENEIDA database, and it is generally evaluated at the time of IBD diagnosis, before starting immunosuppressive treatment. The ENEIDA registry has the advantage over large population studies that researchers have access to relevant details of the clinical history, which can respond to the controversies raised. This multicenter retrospective descriptive study will provide useful information to be able to give evidence-based recommendations regarding treatment of HCV in patients with IBD.

Ulcerative colitis (UC) and Crohn's disease (CD) are chronic relapsing inflammatory bowel diseases (IBD). At the time of diagnosis it is not possible to predict the course of the disease, which can range from a few flares in a lifetime to uncontrollable disease leading to hospitalization, surgery and stoma. There is a continuous need to improve diagnostic and prognostic tools. In chronic inflammation diseases there is an excessive turnover of the extracellular tissue. Tissue is broken down to small fragments and released into the circulation. Changes in the amount of these fragments in the blood may provide information on the damage and quality of the affected tissue and may therefore act as objective measure of disease burden and severity - a so called biomarker. The potential of such biomarkers is evaluated in a combined cross-sectional and longitudinal survey including 300 patients with UC, CD, irritable bowel disease and healthy controls. The patients are followed for up to 1 year. Changes in biomarker are correlated to standard markers of inflammation during active disease and remission. Perspective The use of new biomarkers may offer a tool to evaluate early changes in the gut of patients with IBD, may be a supplement to the diagnosis, serve as markers for effect of treatment and prognosis, and in time be a good alternative to fecal samples or endoscopy.

To evaluate the safety and efficacy of the NaviAid™ AB in children with known or suspected IBD.

The investigators will test the hypothesis that that greater efficacy of anti-tumor necrosis factor (antiTNF) therapy results in reduced need for bowel resection surgery, fewer serious infections, and reduced short term mortality risks, and therefore has a more favorable benefit to harm profile than corticosteroids for inflammatory bowel disease.

Consequences of Colon Hydrotherapy plus probiotic intervention on composition of GI microbiota and well being are analysed in subjects claiming GI inconveniences due to Irritable Bowel Syndrome or food intolerances.

Drug serum concentrations will be measured at several time-points for inflammatory disease patients treated with anti-TNF agents. The purpose is to determine which patients that will clinically benefit from either discontinue treatment, adjusting the dose, switch to another anti-TNF agent or a different class of medication.

The transition from pediatric to adult IBD care can be stressful and wrought with challenges including access to care and establishment of new physician-patient relationships. There a few studies which characterize patterns of healthcare utilization during this critical period and its impact on outcomes. We hypothesize that uninterrupted healthcare utilization in academic centers and optimized communication with patients during the pediatric-adult transition period is associated with lower hospitalizations and surgery. This hypothesis will be addressed by a randomized clinical trial to determine the impact of monthly regular telephone contact with an IBD Registered Nurse versus standard of care during the pediatric-adult transition period. Outcomes will include healthcare utilization, health-related quality of life, patient satisfaction, and treatment adherence over 12 months of follow-up. Randomization and analyses will be stratified by whether subjects were transferred to adult care in an academic center or in a community practice. We hope that this research will facilitate optimal delivery of healthcare during the pediatric-adult transition.
