View clinical trials related to Celiac Disease.
Filter by:Celiac disease (CD) is a common auto-immune disorder induced by gluten ingestion in genetically susceptible individuals (HLA-DQ2/DQ8). Gluten induces small-bowel villous atrophy and a specific immune response characterized by the production of CD-autoantibodies against transglutaminase 2 (anti-TG2) and endomysium (EMA). In symptomatic patients with positive-serum antibodies and villous atrophy, the diagnosis of CD is clearcut. However, 10-30% of patients evaluated for suspected CD show only mild histopathologic changes and fluctuating serologic markers, a condition identified as potential CD. In such cases the diagnosis may remain uncertain. CD-autoantibodies are produced by intestinal B-cells in the early phases of the disease, before their appearance in the serum and when the duodenal mucosa is still normal. Intestinal CD-antibodies (I-CD-abs) are a marker of CD, have a high sensitivity and specificity for CD and identify those patients with potential CD who are at risk of progression to villous atrophy. I-CD-abs can be detected by double immunofluorescence staining on frozen duodenal sections or by using an endomysial antibody assay in the culture medium of duodenal biopsies (EMAbiopsy). The diagnostic accuracy of these techniques is comparable as they both have high sensitivity and specificity. However, their implementation in clinical practice is limited because they require both experienced operators and well-equipped laboratories. There is an unmet need: the development of a new simple and effective diagnostic tool that any gastroenterology unit can use in routine diagnostics to ensure a prompt diagnosis in suspected CD patients, who may benefit from a therapy based on gluten-free diet, and to reduce both unnecessary medical investigations and diagnostic delays. In order to simplify and shorten times for the detection of these intestinal antibodies, the study aims to substitute the EMAbiopsy assay with a supernatant obtained quickly after mechanical lysis of fresh intestinal biopsy specimen. The obtained samples will be tested with rapid (about 15 minutes) immune-chromatographic anti-TG2 assay (Rapid Intestinal anti-TG2 Assay).
Recent studies have also shown that 30% of the world's population carries the susceptibility genes for coeliac disease and that only 2-5% of these individuals are really affected, however, studies suggest the existence of other factors capable of contributing to the onset of the disease, such as intestinal dysbiosis. We have also seen how each of us has a specific microbiota, defined as an individual human enterotype, which depends on our background and can be modified by the diet. Recently, much interest has been directed to a strain of lactobacilli, called Lactobacillus plantarum (LP-LDL®) capable of reducing cholesterol and preventing the reabsorption of bile salts in the liver. The efficacy of this bacterial strain has been confirmed in 3 different human studies demonstrating the efficacy of LP-LDL® in patients with high baseline cholesterol (TC> 6mmol / L). This is a food supplement that has been commercially available in multiple formulations in Europe for over 3 years. LP-LDP is a probiotic strain, safe to use, selected for its high bile salt hydrolase in vitro, and in vivo cholesterol reduction activity. The intake of 2 Å~ 109 CFU encapsulated LP-LDL twice daily, significantly reduced LDL-C (13.9%), total cholesterol (TC) (37.6%), TG (53.9%), and significantly increased HDL-C (14.7%; in subjects >60 years of age; 6-12 weeks) in normal to mildly hypercholesterolaemic subjects. In a recent double-blind placebo-controlled human study published by the Journal of Functional Foods (2022) and carried out by the University of Roehampton (UK), LPLDL showcased statistically significant reductions in multiple cardiovascular risk biomarkers, including total cholesterol, LDL cholesterol, non-HDL cholesterol and apoB. No adverse effects were noted throughout the study. We are here proposing a pilot human intervention study to evaluate the effectiveness of the LP-LDL® probiotic in reducing cardiovascular risk factors inclusive of cholesterol in the blood in people with coeliac disease.
Patients participating to this study will provide images and videos of capsule endoscopy to train, tune and evaluate technological bricks of artificial intelligence solutions, in order to improve diagnostic performances of the procedure, while reducing reading time by physicians.
The study will compare the immune response in CeD patients to wheat and barley gluten at high doses (1 gram), and also investigate the reponses to low dose barley gluten and also hydrolyzed, malted barley. This will be done by four one-day challenges with intervals around four weeks.
Psychological distress (anxiety and depression) is common in and experienced differently by people living with long-term health conditions (LTCs). Being able to measure whether psychological distress is related to living with a LTC would allow researchers and clinicians to provide interventions specifically tailored to the challenges of living with a LTC and therefore provide the most appropriate support for these patients. Such a measure would also be useful in research to identify the presence of illness-related distress in different patient groups. This project will therefore create a new measure of illness-related distress that has applications for both research and clinical practice. This will involve the psychometric validation of the new illness-related distress measure to test how valid and reliable the measure is. The aim of the project is to provide initial validation of the Illness Related Distress Scale in a community sample, recruited through online platforms. The objective of the study is to gather initial validity and reliability data for the scale.
The study goal is to evaluate the efficacy, safety, and tolerability of KAN-101 in participants with Celiac Disease (CeD)
The main objective of this multicenter and observational study is to define the optimal threshold of different commercially available IgA anti-transglutaminase (tTG-IgA) antibody assays for celiac disease diagnosis (CD) avoiding the need for an intestinal biopsy. The main questions to be answered are: - Is the anti-tTG-IgA titer cut-off above 10 times the upper limit of normal (ULN) useful in all anti-tTG IgA assays? - Is the diagnostic performance of the newly defined cut-offs of anti-tTG-IgA the same in all the evaluated assays? - Is the dynamic of the anti-tTG-IgA levels after the introduction of the gluten-free diet (GFD) similar across the different assays included in the study? This is a prospective multicenter study that will enroll pediatric and adult patients with new-onset CD during the years 2023 and 2024. Serum from these patients will be collected for the determination of anti-tTG-IgA according to the local methodology (participating hospital) and by the anti-tTG IgA assays most commonly used in our country, which will be centralized in the same reference center (Hospital Universitario La Paz).
Longitudinal prospective multicenter Armenian registry of systemic autoimmune, autoinflammatory diseases with constitution of bio-banking.
The goal of this clinical trial is to reduce inflammation and improve glycemic control in healthy volunteers, parents, as well as children, adolescents and adults with or without diabetes. The main questions it aims to answer are: • does a reduction wheat gluten improve glycemic control and/or inflammatory biomarkers • does a reduction in certain amino acids (which is most common in wheat gluten) improve glycemic control and/or inflammatory biomarkers • can we identify individuals with an inflammatory response, which leads to poor glycemic control. Participants will eat gluten-free products as well as similar products containing gluten. They will also eat gluten together with probiotics to see if an effect of gluten can be reduced. Researchers will compare everyone with themselves (cross-over design) and if possible individuals with and without diabetes.
The study aims to determine the effectiveness on the tear film quality and symptoms related with dry eye disease in patients with celiac disease.
