View clinical trials related to Celiac Disease.
Filter by:Celiac disease is a disorder caused by a disregulation of the immune system which leads to immune response to gluten. Diet therapy is the gold standard of treatment, and the only effective one. Macronutrients and micronutrients deficiency (vitamin D, folic acid, vitamin B12, vitamin B6, iron and zinc), which is in any case far more common in patients who don't follow gluten free diet, can persist in a subset of patients who follow gluten-free diet. Supplementation of vitamins in these patients may have a beneficial role. A recent study in a murine model showed that supplementation with probiotic VIVOMIXX® leads to an increase in expression of vitamin D receptors in proximal and distal colon. This is an interventional controlled randomized double blind study, which evaluates the effect of VIVOMIXX® on vitamin status.
This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records regarding Celiac Disease.
The incidence of autoimmune diseases (celiac disease, type 1 diabetes, thyroid disease) have increased over the past 30 years. Although most autoimmune diseases have a strong link to different risk genes, the rapid increase is thought to be due to changes in environmental factors. There is currently no cure for autoimmune diseases, but the treatment is lifelong and either involves suppressing the inflammation and / or substituting the organs that are affected to maintain vital functions. Being able to predict who is affected and identifying factors that trigger autoimmunity is necessary for developing new treatment methods that prevent the occurrence of autoimmune diseases. The bacterial flora's composition in the gut can affect both the intestinal barrier properties and the immune system's response to various dietary components. An adverse composition of the intestinal flora can activate parts of the immune system that are involved in chronic inflammation in celiac disease and inflammatory bowel disease. Probiotics are defined as living microorganisms which, when ingested in sufficient amounts, produce a health effect (FAO / WHO). The aim of the study is to investigate whether a daily oral intake of a mixture of L.paracasei and L.plantarum can affect the autoimmune process in children who are screened positive for any of the autoantibodies associated with development of celiac disease, type 1 diabetes and / or thyroid disease. Our hypothesis is that lactobacilli can directly regulate the autoimmune process in the small intestinal mucosa by stimulating regulatory T-cells, but also by affecting the permeability of the small intestinal mucosa by of antigen that stimulates specific T-cells.
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.
This project is expected to confirm the hypothesis that hyposplenism in patients with celiac disease is not conditioned by a selective memory deficiency of B lymphocytes. Other objectives of project are: - determination of gliadin 33-mer in faecal and urine as indicators patient´s adherence to gluten-free diet - determination of citrulline in plasma as an indicator of the overall functional capacity enterocytes
This study aims to investigate the impact on 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. Study participants will be randomly allocated to one of the three study groups before the age of 4 months and will remain in that group with the corresponding intervention during the three first years of life. Regular visits to a study nurse and contact with study dietician will be scheduled. The dietician will support the families in keeping the correct diet intended for each study group.
This research aims to develop portable devices - known as fluorescence spectrometers - to monitor the leakage of fluorescent dyes out of the gut into the blood stream. These devices will measure the leakiness (permeability) of the gut in a non-invasive manner and will provide an early warning that patients are at risk of infections caused by the unwanted flow of bacteria from the intestine to the rest of the body.
The introduction of video capsule endoscopy in 2000 has provided a convenient and minimally invasive imaging method for the whole small bowel. Capsule Endoscopy is used to investigate a number of conditions such as obscure gastrointestinal bleeding, iron deficiency anaemia, inflammatory bowel disease, celiac disease, small bowel tumors, and hereditary polyposis syndromes. However, Capsule Endoscopy capsules are not able to suction fluid or wash the intestine, thus making it susceptible to decreased visualization quality and diagnostic yield due to dark intestinal contents or air bubbles. In order to determine the best method for bowel preparation before Capsule Endoscopy, this study seeks to determine in patients undergoing small intestine Capsule Endoscopy if split dose Polyethylene Glycol or single morning dose of Polyethylene Glycol have a benefit in Visualisation quality when compared to clear fluids only. A co-primary outcome will also be the diagnostic yield, as measured by the aggregate of all the active preparation groups compared to than clear fluids only group. Secondary outcome measures will include tolerance of preparations, cleanliness as assessed by a validated 4 point scale, distal small bowel visualization (the last 1/4 of small bowel examination by time) and small bowel transit time (measured as time from first duodenal image to first cecal image). Adult outpatients referred for small bowel video capsule endoscopy will be considered for the study and this will run in the clinical environment as per routine. Patients will have been referred for capsule endoscopy as per normal clinical practice so not additional procedure will take place. Patients will be randomly assigned to in a one to one fashion to one of three groups in order to explore whether bowel preparation (either as a single or divided dose) produce better cleansing and diagnostic yield than no preparation at all in small bowel capsule endoscopy.
Video capsule endoscopy (VCE) is recommended as the gold standard in small bowel exploration. The efficiency of the axial-viewing (Given, Imaging) has been widely reported. The CapsoCam capsule (Capsovision, California, USA) has four cameras allowing the exploration of the small bowel through 360 degree lateral viewing. Celiac disease is the most common autoimmune enteropathy in Western countries, and is usually associated with a good response to the gluten free diet and an excellent prognosis. However, a minority of patients develop complications of the disease, such as refractory celiac disease, ulcerative jejunoileitis and neoplastic complications such as adenocarcinoma of the small bowel and enteropathy associated T cell lymphoma. In recent years, the detection of small bowel lesions has dramatically improved thank to the availability of capsule endoscopy exploration. The aim of this study was to evaluate detection rate and diagnostic concordance of the axial view capsule and CapsoCam capsules in the same patients.
The overall aim of this project is to investigate whether a gluten free diet after the onset of type 1 diabetes (T1D) can better preserve the remaining beta cell mass and at the same time prevent the development of Celiac Disease (CD) in these patients. Specific aims • To study whether gluten free diet during one year after the onset of diabetes influence the appearance and duration of clinical remission in children with Type 1 diabetes. New data show that a gluten free diet is beneficial concerning the insulin production after the onset of diabetes. The investigators want to investigate if gluten is a triggering protein for the destruction of the beta cell function after the onset of diabetes by comparing children who have a normal diet compared to children with a gluten free diet during one year after the onset of the disease. - To study whether a gluten free diet during one year after the onset of diabetes prevent the development of Celiac Disease in these children and the impact of having two diseases It is known that it is almost 10 times more common that children with Type 1 Diabetes (IDDM) develop Celiac Disease (CD) than the general population and that most of these children (6-7 %) develop CD after the onset of Diabetes and within 5 years. Based on our new data that CD is preventable to some extent the investigators plan to perform randomized controlled studies if it is possible to prevent or postpone CD by means after the onset of IDDM. - To investigate the impact of gluten free diet on the regulation of autoimmune responses The investigators will test the hypothesis that gluten free diet in children with recent onset T1D will implement immune regulation and inhibit the activation of potentially autoreactive T cells.
