View clinical trials related to Celiac Disease in Children.
Filter by:A retrospective monocentric observational no-profit study with the aim of evaluating the entity and potential variables influencing the catch-up growth of childhood gluten-free diet patients with celiac disease during a 10-year follow-up. The only extrapolation of the data collected in anonymized form from the medical records of patients who match the necessary study criteria will be planned in order to achieve this aim. A 900-patient sample size will be planned.
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).
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.
This is a study of immune responses after eating gluten powder in people with celiac disease and healthy controls.
Study is an interventional clinical trial. children (aged 6-18 years) diagnosed with type 1 diabetes and celiac disease will be recruited conveniently from Endocrinology pediatric clinic at Prince Hamzah Hospital. Amman, Jordan. A sample of 45 diagnosed children, who will meet the inclusion criteria and will be agreed to participate will be centrally randomized to follow carbohydrate counting with GFD dietary intervention, carbohydrate counting with GFD and DASH dietary intervention, and control dietary intervention.
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.
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.
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.
