NCT07239336
The main aim is to see how DONQ52 works to improve small intestinal damage and reduce celiac-related symptoms due to gluten exposure, in participants with celiac disease (CeD) attempting to maintain a gluten-free diet (GFD) in treated participants versus placebo controls.
NCT06356220
The investigators propose the Gluten Free Nutrition Optimization through Ultra-processed food Reduction and Improved Strategies for Health (GF-NOURISH) study to demonstrate the feasibility and success of a nutritional education program focused on naturally occurring gluten-free foods and minimizing ultra-processed gluten-free foods. The investigators hypothesize that nutritional educational (GF-NOURISH) intervention will have multiple health benefits
NCT07069127
This single-center, randomized controlled clinical trial aims to evaluate the effectiveness of a home-based treatment using hydroxyapatite-based oral care products in adult patients with celiac disease who exhibit enamel demineralization and dentin hypersensitivity. Forty patients will be enrolled and randomly allocated into two parallel groups. The control group will perform home oral hygiene using only a hydroxyapatite-based toothpaste (Biorepair® Total Protection) twice daily. The trial group will follow the same regimen with the toothpaste, but will also apply a hydroxyapatite mousse (Biorepair® Plus Intensive Enamel Repair) once every evening before bedtime throughout the study period. The primary objective is to assess the reduction in dentin hypersensitivity using the Schiff Air Index. Secondary outcomes include changes in plaque accumulation (Plaque Index), gingival bleeding (Bleeding on Probing), pain perception (Visual Analogue Scale), and caries experience (DMFT and DMFS indices). Enamel demineralization will be analyzed through near-infrared transillumination (DIAGNOcam), laser fluorescence (DIAGNOdent), and digital image analysis (ImageJ software). All clinical parameters will be evaluated at baseline and after 1 week, 1 month, 3 months, and 6 months. The study seeks to determine whether the addition of a remineralizing mousse to daily oral care provides superior benefits in reducing sensitivity and improving enamel integrity in patients with celiac disease.
NCT06001177
The study goal is to evaluate the efficacy, safety, and tolerability of KAN-101 in participants with Celiac Disease (CeD)
NCT07157137
Although a gluten-free diet (GFD) is essential for patients with coeliac disease (CD), many do not follow it strictly. Exposure to gluten causes villous atrophy, can deteriorate nutritional status, and can lead to deficiencies. The ESPGHAN recommends combining multiple methods to assess GFD adherence. The Celiac Dietary Adherence Test (CDAT) and measuring the gluten immunogenic peptide in urine (uGIP) or stool (sGIP) were suggested. This study aims to evaluate and compare the usefulness of an adapted CDAT, the rapid tests for detecting uGIP and sGIP, for assessing adherence to a GFD in children with CD. Additionally, we will assess these children's nutritional status. Patients, aged 2-18 years, diagnosed with CD, who have been on a GFD for at least 6 months, will be included. Clinical characteristics and anthropometric measurements will be recorded. The adapted CDAT form will be applied. A single urine and stool samples will be collected immediately, and rapid tests for the detection of GIP will be performed. The serum levels of anti-transglutaminase antibodies (IgA), albumin, ferritin, folate, vitamins B12, A, E, 25-OH vitamin D, blood count and lipid profile will be measured.
NCT03562221
This study aims to investigate the impact of being on a gluten free diet the first three years of life compared to a daily intake of a probiotic supplementation or placebo on the risk of developing celiac disease autoimmunity or celiac disease in genetically susceptible children. This is a three-arm (1:1:1) randomized trial where study participants are randomly allocated to one of the three study groups before the age of 4 months. Regular clinical visits (4 times/year) during the intervention phase and yearly there after, up to the age of 7 years.
NCT03678935
The first aim of the study is to investigate the prevalence of persistent gastrointestinal symptoms and compliance with gluten-free diet and the intake of FODMAP in adult celiac patients. A web-based survey wil be performed and thereafter a randomized controlled trial to test the effect of a FODMAP reduction in patients with celiac disease with irritable bowel-like symptoms.
NCT06059716
The investigators propose to plan for a multi-center randomized controlled trial (M-RCT) to test the effectiveness of novel gluten detection technologies as an adjunct to telemedicine to manage celiac disease in newly diagnosed adults. If successful, the proposed intervention will improve mucosal recovery, promote a shift in current practice of celiac disease management toward long-term monitoring, and represent a significant step toward reducing the severe physical and psychological consequences of celiac disease.
NCT07039773
The goal of this clinical trial is to evaluate the immune response to gluten in patients with celiac disease (CeD) by comparing different forms of gluten administration. The participant population includes adults diagnosed with CeD, who are adhering to a gluten-free diet (GFD). The main questions it aims to answer are: * Does liquid gluten administration elicit a higher IL-2 cytokine response compared to solid gluten administration? * What is the relationship between serum IL-2 levels and gluten peptide serum concentrations following gluten challenges? Researchers will compare the responses of two groups: participants receiving liquid gluten (shake) to those receiving solid gluten (cookie) to determine if there is a significant difference in the IL-2 response rates between the two forms. Participants will be asked to: * Undergo two gluten challenges (liquid and solid) in a randomized order with at least 4 weeks apart. * Provide blood samples before and after each challenge to measure serum IL-2 levels and gluten peptide concentrations over a period of 6 hours. * Report any symptoms experienced following each gluten challenge.
NCT06657001
The goal of this observational research study is to determine how diet contributes to various gastrointestinal related conditions. The main question investigators aim to answer is: Are host genetics, diet, and microbiome all important determinants of GI disorders, and how their relative contribution varies among individuals and populations.
NCT06921343
This study aims to understand how to best manage iron deficiency in children newly diagnosed with celiac disease. Many children with celiac disease have low iron levels, even if they do not have anemia. While some doctors recommend iron supplements, others believe that simply following a gluten-free diet may be enough to restore iron levels naturally. In this study, children with newly diagnosed celiac disease and low iron levels (but normal hemoglobin) will be randomly assigned to one of two groups: Gluten-Free Diet Only - No additional iron supplements Gluten-Free Diet + Iron Supplementation Researchers will compare iron store levels over one year to see if iron supplements provide any additional benefit beyond the gluten-free diet alone. The study will also track possible side effects of iron supplements, such as stomach discomfort. This study will help doctors determine the best approach to managing iron deficiency in children with celiac disease, ensuring they receive the safest and most effective treatment.
NCT05425446
This study is to characterize the safety and tolerability of an investigational drug called DONQ52 and consists of a single ascending dose part (Part A) and a multiple ascending dose part (Part B) in well-controlled celiac disease patients.
NCT06007898
Managing a strict gluten-free diet is crucial for children and young people with coeliac disease. However, this can have adverse effects on psychological well-being and quality of life. Despite appeals from families, clinicians, and researchers, psychological support is not routinely provided to these families. This project aims to adapt existing self-help psychological resources used for food allergy, gastrointestinal disease, and type one diabetes to cater to families dealing with coeliac disease. The process involves collaboration with families and clinicians to modify these resources. Subsequently, a feasibility randomised controlled trial will be conducted to assess the viability and acceptability of these resources. In the trial, 50 families will complete well-being and quality of life questionnaires, along with assessments of their child's gluten-free dietary management. Families will be divided into groups receiving the psychological resources either immediately or after a two-month delay. Follow-up questionnaires will be administered at one and two months for all families, regardless of intervention access. Feedback on the resources and research participation will be gathered. The expectation is that these self-help psychological resources for parents will enhance gluten-free diet management, quality of life for coeliac children and young people, and well-being for parents.
NCT04014413
The gut microbiota is critical to health and functions with a level of complexity comparable to that of an organ system. Dysbiosis, or alterations of this gut microbiota ecology, have been implicated in a number of disease states. Fecal microbiota transplantation (FMT), defined as infusion of feces from healthy donors to affected subjects, is a method to restore a balanced gut microbiota and has attracted great interest in recent years due to its efficacy and ease of use. FMT is now recommended as the most effective therapy for CDI not responding to standard therapies. Recent studies have suggested that dysbiosis is associated with a variety of disorders, and that FMT could be a useful treatment. Randomized controlled trial has been conducted in a number of disorders and shown positive results, including alcoholic hepatitis, Crohn's disease (CD), ulcerative colitis (UC), pouchitis, irritable bowel syndrome (IBS), hepatic encephalopathy and metabolic syndrome. Case series/reports and pilot studies has shown positive results in other disorders including Celiac disease, functional dyspepsia, constipation, metabolic syndrome such as diabetes mellitus, multidrug-resistant, hepatic encephalopathy, multiple sclerosis, pseudo-obstruction, carbapenem-resistant Enterobacteriaceae (CRE) or Vancomycin-resistant Enterococci (VRE) infection, radiation-induced toxicity, multiple organ dysfunction, dysbiotic bowel syndrome, MRSA enteritis, Pseudomembranous enteritis, idiopathic thrombocytopenic purpura (ITP), and atopy. Despite FMT appears to be relatively safe and efficacious in treating a wide range of disease, its safety and efficacy in a usual clinical setting is unknown. More data is required to confirm safety and efficacy of FMT. Therefore, the investigators aim to conduct a pilot study to investigate the efficacy and safety of FMT in a variety of dysbiosis-associated disorder.
NCT05135923
High intake of dietary fiber provides health benefits and reduces the risk of developing cardio-metabolic diseases, such as type 2 diabetes (T2D) and cardiovascular disease (CVD). The intake of fiber is below the recommendations worldwide. In Norway, bread and cereals represent a major source of fiber. A low fiber intake is evident for people with celiac disease due to the removal of wheat, rye and barley from the diet. We therefore need to increase our knowledge in relation to fiber-rich food that will be tolerated also by people with celiac disease. The aim of the study is to investigate the effect of fiber rich gluten free products on blood glucose levels compared to benchmark gluten free products.
NCT04839575
This is a phase 2, single-center prospective, double-blind, placebo-controlled, crossover study in Type 1 diabetes and celiac disease subjects attempting a GFD for at least one year prior to screening.
NCT06500754
Celiac disease (CD) is an immune-mediated disease characterized by small intestinal inflammation from gluten ingestion, a group of proteins present in various cereals, including wheat, rye, barley, spelt, and kamut. CD is the most common chronic gastrointestinal disease and one of the most common autoimmune disorders, estimated to affect 0.4-1.7% of the general population. Currently, a strict lifelong gluten-free diet (GFD) is the only available treatment to avoid the inappropriate inflammatory response and prevent the shortening of the villi lining the small intestine (villous atrophy). However, a significant proportion of CD patients, ranging from 4% to 79%, show persistent villous atrophy despite following an intentional GFD. The causative factors and the clinical consequences of persistent villous atrophy in CD patients are not well known yet but might resemble untreated CD long-term complications. Interestingly, in the precedent study (CADER) persistent villous atrophy was found to be more present in patients diagnosed at an older age (65% of CD patients diagnosed after 30 years of age) than in younger patients. Moreover, unintentional exposure to gluten was found in 70% of the cases. The causative factors of this hypersensitivity to small amounts of gluten present in older patients are unknown. The intestinal microbiota and age-related epigenetic changes may help maintaining the dysregulation of the immune response, causing older patients to be hypersensitive to small amounts of gluten. The aim of this study (CADER2) is to identify the immunological and clinical consequences of persistent villous atrophy in CD and study whether changes in the intestinal microbiome and age-related epigenetic modifications may contribute to it. Last, the investigators want to assess if an ultra-strict GFD can be a viable and effective alternative to treat this subset of CD patients. In order to achieve these objectives, the study includes 2 phases: 1) Cross-sectional study to assess the causes and the clinical consequences of persistent villous atrophy in CD patients; and 2) Longitudinal study to evaluate the potential therapeutic effect of an ultra-strict GFD on persistent villous atrophy and its subtle clinical manifestations. The investigators hypothesize that persistent villous atrophy in CD patients despite an intentional GFD is associated with chronic low-grade inflammation and increased circulating cytokines in blood, potentially leading to cognitive deficits, fatigue, anxiety, depression, malnutrition, sarcopenia and osteoporosis. The intestinal microbiota and age-related epigenetic changes may help to maintain the dysregulation of the immune response, causing patients to be hypersensitive to small amounts of gluten. This subset of CD patient could highly benefit from an ultra-strict GFD. To date, six centers have been recruited: Hospital Universitari Mutua Terrassa (Barcelona), Hospital Clínico San Carlos (Madrid), Hospital Fundación Jiménez Díaz (Madrid), Hospital Universitario de La Princesa (Madrid), Hospital Universitario Ramón y Cajal (Madrid) and Hospital Universitario Virgen Macarena (Sevilla). Digestive, endocrine, nutritional and clinical psychology experts will be involved in the monitoring of the patients. Microbiome analysis will be performed at the Genomics Unit, Microbiota Laboratory (LABMIC) of the IdISSC (Madrid). The methylation studies (age-related epigenetic modifications) will be hired externally. Overall, the results of this study (CADER2) may help identify new therapeutic strategies as well as improve the management of chronicity and care of CD patients who do not respond to the current treatment. Furthermore, it will contribute to a deeper understanding of the pathophysiological relationships between diet, microbiome, genetics and immunology in CD.
NCT04593251
This is a single and multiple ascending study to characterize the safety, PK, PD and clinical effect in healthy volunteers and participants with Celiac Disease and Eosinophilic Esophagitis.
NCT03707730
To assess the efficacy and safety of AGY vs placebo when administered to individuals age 10 to 65 years with medically proven CD and on a gluten free diet
NCT06038344
Celiac disease (CD) is an autoimmune gastrointestinal disease that is caused by intolerance to gluten in the diet. The mainstay of treatment is a gluten-free diet (GFD). Children with CD on the GFD often have low micronutrient intakes (e.g. folate, iron) and high intakes of sugar and fat. Current Canadian nutrition guideline does not address these nutritional limitations. The investigation team developed a novel GF-food guide (GFFG). This randomized clinical trial aims to evaluate the impact of GFFG on diet quality and adherence to the GFD in newly diagnosed children and youth with celiac disease in the clinical setting. The investigators will compare dietary counselling using the GFFG versus the standard of care in children newly diagnosed with CD and their parents to see if participant care outcomes (diet quality, nutrition literacy, adherence to the GFD) improved over six months.
