Filter by:By conducting a randomized controlled study of the role of enteral nutrition biscuits in the induction of remission in moderate-to-severe Crohn's disease, we will evaluate to investigate the role of enteral nutrition biscuits in the induction and remission phases of moderate-to-severe Crohn's disease; to assess patient adherence to enteral nutrition biscuits and the timing of their application; to assess the role of enteral nutrition biscuits in biologically refractory patients; and to assess the role of enteral nutrition biscuits in the remission of perianal, small bowel, and colonic lesions.
The research group have previously evaluated the benefit of serial consecutive capsule endoscopy as monitoring tool for Crohn's disease in remission, demonstrating its superior accuracy for disclosing inflammation and for prediction of flares in comparison to other diagnostic modalities such as magnetic resonance enterography and inflammatory biomarkers. Subsequently, deep learning algorithms had developed to provide excellent accuracy for identification and grading of ulcers and intestinal strictures on capsule endoscopy still images. The investigators will advance this knowledge using a parallel two-parts approach.
This clinical trial aims to understand the feasibility of patients taking ketone body supplement beta-hydroxybutyrate (BHB) for 4 weeks with a confirmed diagnosis of Crohn's disease and starting new therapy for active disease. The main questions it aims to answer are: - BHB supplementation will be feasible and acceptable to patients. - BHB supplementation will be associated with a reduction in systemic inflammation. - BHB supplementation will be associated with a reduction in pro-inflammatory bacterial colonies. Participants will: - Take 3 capsules x 3 times per day for 4 weeks. - Document food consumption using a 24-hour food recall questionnaire. - Provide blood and fecal samples twice, at the beginning of the study and the 4-week mark. Researchers will compare the group taking the ketone body supplement and the group not taking the supplement to see if the supplement provides relief of symptoms suffered from Crohn's disease.
Crohn's disease (CD) is a long-lasting disease that causes severe inflammation (redness, swelling), in the digestive tract, most often affecting the bowels. It can cause many different symptoms including abdominal pain, diarrhea, tiredness, and weight loss. This study will assess how safe and effective oral Upadacitinib is in treating moderately to severely active Crohn's Disease in pediatric participants aged 2 to 18 years old who have had inadequate response, loss of response, intolerance, or medical contraindications to corticosteroids, immunosuppressants, and/or biologic therapy. Upadacitinib (RINVOQ) is a drug approved in adults for moderate- to severely active CD and is being developed for moderate- to severely active CD in pediatric participants. This study is conducted in 2 periods: Period 1 is comprised of two phases: a 12-week open-label induction phase which means that the study doctor and participants know that participants will receive UPA Dose-A (or the adult equivalent based on body weight) followed by a 52-week double-blind maintenance phase meaning that neither the participants nor the study doctors will know which dose of upadacitinib will be given(UPA Dose B or Dose C). Period 2 is a 156-week open-label extension of Period 1. Approximately 110 pediatric participants with moderate to severely active CD will be enrolled at approximately 92 sites worldwide. Participants will receive upadacitinib oral tablets once daily or oral solution twice daily at approximately the same time each day, with or without food. Participants will have a safety follow up for 30 days after discontinuation from any time point within the study. There may be higher treatment burden for participants in this trial compared to their standard of care (due to study procedures). Participants will attend regular (weekly, monthly) visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
Aim of the study: To evaluate risk factors of endoscopic relapse after ileocolic resection in a cohort of Crohn's disease patients treated with anti-TNF agents. Methods: From 2014 to 2022, all consecutive patients who underwent ileocolic resection for Crohn's disease treated with anti-TNF agents in two referral tertiary center were prospectively collected. Considering exclusion criteria, data from 114 patients were analyzed. The cohort was separated into 2 groups according to study period. Short and long-term outcomes were compared between the two groups. Primary outcome: Endoscopic recurrence (defined as > i2 lesions according to Rutgeerts classification) 6 months after surgery
The goal of this clinical trial is to learn about the effects of fluconazole in patients who plan to or are undergoing standard of care treatment with an IL-23 therapy for their Crohn's disease. The main question it aims to assess is will patient response to IL-23 therapies improve when simultaneously treated with fluconazole.
The primary aim of this study is to explore the time course of response to Vedolizumab in participants with CD as measured by the Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference-short form (SF), as well as other PROMIS domain SFs (fatigue, anxiety, depression, sleep disturbance, physical function, and ability to participate in social roles and activities); other PRO measures will also be assessed.
Crohn's disease (CD) belongs to chronic inflammatory bowel diseases (IBD) affecting over 2 million individuals in the North America and 3.2 million in Europe with an increasing incidence rate in newly industrialized countries experiencing a westernization of lifestyle (1). This highly disabling disease affects patients' life in several ways with severe complications requiring surgery for half of them and is responsible for considerable economic burdens (2,3). Decades of research displayed that CD pathogenesis is determined by inappropriate immune responses towards luminal microbiota in genetically susceptible hosts. Genome-wide association studies (GWAS) have identified autophagy as one of the main pathways associated with susceptibility to CD (4-6). Autophagy is a dynamic process of the lysosomal catabolism, called autophagy flux, which is crucial to degrade and recycle obsolete and deleterious cytosolic components of the cell (7). Autophagy is also the main cell-autonomous process to fight intracellular microorganisms by degrading them, and by contributing to antimicrobial host immune responses. However, the functional consequences of polymorphisms affecting autophagy-associated genes on the dynamic process of autophagy and its real impact on CD pathogenesis remain largely unknown. In addition, CD is associated with a gut microbiota dysbiosis, as exemplified by the higher prevalence of AIEC (a bacterium eliminated by autophagy) in ileal mucosa of CD patients (8-10). Hence, autophagy defect, linked to autophagy SNPs, could contribute to CD-related dysbiosis and to CD activity and severity. Beyond, CD-associated abnormalities of the autophagy flux may affect the composition of the autophagic cargoes, as well as the one of other vesicular pathway, such as exosomes, known to influence autophagy. These impairments could affect at longer term both cell activities and immune responses, especially in antigen presenting cells, which drive host immune responses. The TOPIC project concerns translational research, in which we plan to generate a prospective cohort of CD patients giving up the unique opportunity to collect clinical data, to analyse simultaneously the autophagy flux, genetic variants of interest (from blood samples) and intestinal microbiota (from intestinal samples) and allowing to perform more fundamental studies. The results of the fundamental part will allow a better understanding of the pathophysiology of CD, and ultimately better management of these patients.
Crohn's disease (CD) is a long-lasting condition causing inflammation that can affect any part of the gut. The purpose of this study is to evaluate the efficacy and safety of TAK-279 versus placebo in participants with moderately to severely active Crohn's disease (CD). The main aim of this study is to learn if the 3 different doses of TAK-279 reduce bowel inflammation and ulcers in the bowel compared to the placebo after 12 weeks of treatment. Another aim is to compare any medical problems that participants have when they take TAK-279 or placebo and how well the participants tolerate any problems. An endoscopy will be used to check the bowel for inflammation. The participants will be treated with TAK-279 for 52 weeks (1 year). During the study, participants will visit their study clinic 15 times.t
The main aim of this study is to learn whether vedolizumab and upadacitinib given together (also called dual targeted therapy or DTT) reduces bowel inflammation and ulcers in the bowel compared to vedolizumab only (also called monotherapy) in adults with moderately or severely active Crohn's Disease (CD) after 12 weeks of treatment. Other aims are to learn how safe and effective DTT is compared to monotherapy for these participants. All participants will receive DTT (either vedolizumab and upadacitinib or vedolizumab and placebo) for 12 weeks. Participants responding to the treatment will then receive vedolizumab only (monotherapy) for an additional 40 weeks. During the study, participants will visit their study clinic 15 times.
