Filter by:An aspect of IBD care that is often overlooked is mental health treatment. Common mental health problems, such as anxiety and depression are very common in IBD, with a meta-analysis estimating prevalence as high as 25.2% for depression and 32.1% for anxiety. The prevalence of anxiety and depression increases when individuals with active disease are considered, with rates as high as 57.6% for anxiety and 38.9% for depression. Comorbid depression and anxiety in IBD is associated with greater symptom severity, even when statistically controlling for disease activity; more frequent and expensive emergency department visits and inpatient stays, higher costs relating to IBD-related surgery, medication and personal expenditure; noncompliance with medical treatment and finally, increased likelihood of experiencing flares. However, very few studies attempt to unpick the precise mechanism of these bidirectional relationships. Indeed, depression and anxiety may have direct effects on physical health through inflammatory or psychoneuroimmunological pathways. Very few studies investigate the longitudinal brain-gut relationship with regards to objective measures of inflammation. Additionally, the indirect effects of mental health are often overlooked. Depression and anxiety are routinely associated with health behaviours, such as diet, physical activity, sleep, and tobacco/alcohol use.These health behaviours are important factors, given their impact on physical health outcomes. Therefore, a thorough investigation is required to ascertain the precise mechanisms that underpin the bidirectional relationship between depression/anxiety and inflammation/physical health, as this will enable practitioners and researchers to establish non-invasive, behavioural treatment targets for this patient group. AIM The broad aim of this project is to explore whether anxiety/depression has a direct or indirect (via health behaviours) on i) inflammation levels ii) clinical activity and iii) healthcare usage at follow-up, in a population of IBD patients. A secondary aim of the project will be to explore whether changes in disease activity, as measured by self-report measures and faecal calprotectin, explains changes in anxiety and depression symptoms at follow up.
The goal of this clinical trial is to learn about the treatment with subcutaneous infliximab in patients with inflammatory bowel disease (IBD) that were previously treated with an optimized dose of intravenous infliximab. The main question it aims to answer is: - Is switching to a weekly dose of subcutaneous infliximab (120 mg) associated with a better outcome compared to the standard fortnightly administration of 120 mg subcutaneous infliximab in patients who received an optimized intravenous dosing schedule? Participants will switch from intravenous infliximab to subcutaneous infliximab and will be randomized to the intervention arm (Subcutaneous infliximab weekly) or the interventional comparison arm (subcutaneous infliximab bi-weekly). Participants will follow daily clinical practice in the monitoring for clinical and biological remission. The participants that are willing to switch to subcutaneous infliximab will be compared to a group of participants not willing to switch. These participants will continue to be treated with their optimized intravenous dose of infliximab.
This study aims to test a new treatment called hyperbaric oxygen therapy (HBOT) for a severe type of inflammatory bowel disease called perianal Crohn's disease (PCD). PCD causes painful perianal infections and chronic drainage from fistula tracts, and current treatments are only moderately effective and may not be suitable for all patients. HBOT is a safe and commonly used treatment for chronic non-healing wounds and other conditions. Previous studies have suggested that HBOT may help heal fistulas in PCD patients, but these studies were small and lacked controls.
In this clinical trial, the intestinal wall of pediatric patients with Crohns disease and Ulcerative Colitis will be assessed with multispectral optoacoustic tomography (MSOT) to characterize the optoacoustic signal of the intestinal wall and to monitor disease activity. The goal of this clinical trial is to compare the optoacoustic signal in the intestinal wall of children with inflammatory bowel diseases. The main questions it aims to answer are: - How does the optoacoustic signal in children with inflammatory bowel diseases change over time? - How does the optoacoustic signal in children with inflammatory bowel diseases change when they receive therapy? Participants will be examined with multispectral optoacoustic tomography.
Crohn's disease is a chronic and complex inflammatory bowel disease affecting the gastrointestinal tract, causing symptoms like abdominal pain, diarrhea, and fatigue. While its exact cause is unclear, it involves genetic, environmental, and immunological factors. Crohn's disease can lead to nutrient deficiencies and has unpredictable flare-ups and remission periods. During the remission phases, irritable bowel syndrome (IBS)-like symptoms can persist in 50% of patients, for which no satisfactory treatment is available yet. Chitin-glucan is prebiotic, obtained by extraction, isolation and purification from a fungal resource: the mycelium of Aspergillus niger (a microscopic fungus of the Ascomycetes family) of which it composes the cell walls. The biopolymer consists essentially of two types of polysaccharide chains: chitin (poly-N-acetyl-D-glucosamine) and beta-(1,3)-D-glucan (D-glucose units linked essentially via beta-1,3 bonds). Because of its beta bond, human intestinal enzymes cannot digest it, as a result, the majority of chitin-glucan can reach the colon where it can be fermented by the microbiota. By modulating the composition and/or activity of the intestinal microbiota, fermentation of chitin-glucan could have beneficial effects on health. The aim of the RELIEVE study is to assess if BK003 could improve the relief of global symptoms, individual symptoms, stool consistency and frequency of evacuations, quality of life, anxiety, and depression in patients with Crohn's disease in remission without treatment or with stable maintenance therapy and having IBS-like symptoms and to confirm the product's safety.
The main aim of this study is to learn how the body of a child or teenager with moderately to severely active ulcerative colitis (UC) or Crohn's disease (CD) processes vedolizumab (pharmacokinetics) given just under the skin subcutaneously (SC). The participants will be treated with vedolizumab for up to 34 weeks. During the study, participants will visit their study clinic several times.
It's of great importance to effectively induce and maintain disease remission in patients with moderate to severe ulcerative colitis (UC). Vedolizumab (VDZ) is known for its high safety profile and confirmed therapeutic efficacy in UC treatment. However, according to the experience in clinical practice, the effect onset speed of vedolizumab is relatively slow. Upadacitinib (UPA), however, works quickly, which complements the defect of slow onset of VDZ induction. However, the safety of UPA used in situations such as infection and tumors is inferior to that of VDZ, and long-term use requires testing for the risk of adverse events such as deep vein thrombosis. Therefore, if the advantages of long-term maintenance therapy safety of VDZ and rapid induced remission of UPA are fully utilized, the combination of VDZ and UPA induction for 8 weeks, followed by the use of single drug VDZ in maintenance therapy, can maximize the clinical benefits of UC patients. Due to the lack of high-level clinical research data at home and abroad, we plan to conduct a multicenter prospective randomized controlled clinical study to provide the evidence-based basis for the efficacy analysis of the sequential treatment of moderate to severe UC patients with VDZ and UPA.
This research study is testing whether changes in sleep timing and morning light treatment may have an impact on symptoms related to inflammatory bowel disease.
This is a French prospective longitudinal observational multicentre cohort study. Primary objective : to assess prospectively the presence and the extent of safety concerns (cancer, serious infections, arterial and venous thrombotic events) in patients with CD and UC and treated with JAKi, anti-IL23p19, and S1p modulators.
Bio-naive participants are defined as the participants who previously have not received any biologics for Crohn's Disease (CD).The purpose of this retrospective study is to describe the endoscopic remission at week 24 among bio-naive participants with CD treated with ustekinumab in China.
