Active clinical trials for "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.

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.

The aim of the investigators' study is to evaluate biochemical, immunological and histological characteristics of patients affected with the so-called "gluten (or wheat) sensitivity" who suffers from irritable bowel syndrome (IBS)-like symptoms. As it is not known what component of the cereals causes the symptoms in so called "gluten-sensitive" patients, the investigators prefer to speak of "not-celiac wheat sensitivity" (NCWS). NCWS patients may be defined as ones, neither celiac or allergic to wheat, who develop symptoms following wheat consumption, that improved on wheat/gluten free diet (GFD). For our research, we will select adult patients, both genders, affected with suspected NCWS (i.e. with symptoms/signs which disappeared on GFD and worsen on a gluten containing diet, testing negative for celiac disease [anti-tissue transglutaminase antibodies, anti-tTG, and anti-endomysium antibodies, EMA, and with biopsy Marsh 0-1] and wheat allergy [serum specific IgE for wheat]). The patients will be recruited at the Department of Internal Medicine, 'Giovanni Paolo II' Hospital of Sciacca (Agrigento), and of Internal Medicine of the University of Palermo, from January 2012 to October 2013, for IBS-like symptoms. At the time of the recruitment, the patients will be on GFD by at least one month and must be asymptomatic. A more restricted elimination diet (with the exclusion of cow's milk, egg and other foods) could be prescribed in patients who are suspected to suffer from multiple food hypersensitivity. The patients will be randomized to undergo a double-blind placebo-controlled study, assuming wheat flour or placebo, administered daily for 15 days. Before and after the challenge, the investigators will evaluate gastrointestinal (Gastrointestinal Symptom Rating Scale, GSRS) and the investigators will collect blood and fecal sampling and biopsies from endoscopic evaluation (both esophagogastroduodenoscopy and rectoscopy, with multiple biopsies), for the identification of possible markers (serological, biochemical, immunological, histological features, expression of cytokines and other constitutive mucosal proteins from peripheral blood mononuclear cells, mucosal lymphocytes and fecal biomarkers) that may be of help to diagnose the condition of NCWS and to understand its pathogenesis.

Celiac disease is a chronic immune-based intestinal pathology. Its prevalence is 1% and its incidence has increased in recent years. This disease usually causes gastrointestinal and/or extraintestinal symptoms, which can only be reduced by following a strict, lifelong gluten-free diet. In addition, the social life of people with celiac disease is impaired due to the impact of the gluten-free diet on daily activities. An adequate Nutrition Education program can improve the physical and social health of these people. Moreover, considering the high impact this disease has on the people close to the celiac patient, and due to the important role that general population has in the care and inclusion of persons with celiac disease, education should be directed to general population. Therefore, the purpose of ZELIAKIDE program is to promote Nutrition Education in general population. In particular, the specific aims are 1) to promote the social inclusion of people with celiac disease by raising awareness among the general population, and 2) to promote a balanced diet and an interest in science and research among children. ZELIAKIDE is an intervention aimed at children and focused on the school environment, and is based on Inquiry Based Learning (IBL) methodology. Inquiry-based Teaching-Learning Sequence (TLS) has been created to internalize and integrate competences related to celiac disease, gluten, gluten-free diet, balanced diet and healthy lifestyle. In addition, this TLS aims to develop scientific competence through activities that promote science and the research process. Although nutrition education programs for children have proven to be effective, it has been observed that children's interest in science has decreased. The investigators therefore aim to implement a nutrition education programme based on previous experiences that promotes science skills and stimulates children's interest in science.

Celiac disease (CD) is an autoimmune disease that occurs in people who are genetically predisposed to gluten consumption (1). The prevalence of the disease is about 1-2% and it is more common in women than in men, and in children than in adults (2). The only current treatment for celiac disease is a strict, lifelong gluten-free diet. This involves the complete elimination of gluten from the diet. Gluten is not only present in some cereals such as wheat, rye, barley and oats, but is also found in many foods that have been processed. In addition to being safe, the gluten-free diet must also be balanced. Following a gluten-free diet creates psychological and social problems for the people who have to follow it (3). It has been seen in several studies that people with celiac condition can feel different and excluded, as it is difficult to eat out, to make sure that the food is gluten-free and to avoid cross-contact (4-8). Due to the complicate situation of people with celiac disease, they do not hesitate to seek information about the management of their diseas. That is why people with celiac disease turn to social networks, as a rapid, visual and accessible way to share information (9-11). In line with the objectives of the University to which the Gluten3S research group belongs to (University of the Basque Country, UPV/EHU), the group has been aware for some time of the importance of disseminating science on social networks in order to make the results of the research reach the general public. It is considered that creating a nutritional education programme about CD and Gluten-Free Diet (GFD), delivered by experts in the field, could be useful in improving knowledge and attitudes about this matter. This will empower people with CD to improve their self-care and take control of their situation. Furthermore, it is also interesting to design the programme in such a way that the impact of the intervention can be measured, always with the intention of continuous improvement and reaching people with celiac disease and their environment in an effective way. The educational intervention will be carried out for one month and is aimed at adults with coeliac disease or adults with coeliac relatives who are involved in their care. Each day a post will be uploaded to Instagram with specific, accurate and current information. The content of the intervention has been divided into 5 main blocks: 1) general concepts about CD, 2) balanced GFD, 3) food labelling, 4) cross-contact/cross-contamination, 5) new research on CD and useful resources for disease management. The evaluation of the intervention will be carried out through pre- and post-intervention questionnaires.

The investigators are conducting a pilot study to investigate the impact of late compared to early introduction of gluten-free oats on gut symptoms, nutrition status, celiac activity and quality of life in patients with a recent diagnosis of celiac disease. Pilot study means that it will recruit a low number of participants to see if it is possible to perform the study, and to estimate how many participants will be needed for the large study. The study will collect information through questionnaires that assess gut symptoms, quality of life, mood changes and dietary patterns. Moreover, the study will collect data on tests done during clinic visits to check the status of patients' celiac markers and nutritional status (such as vitamins and minerals). Physical exam will also take place, and include measurement of weight, BMI and body composition in a 3D scanner. The dietitian will analyze patients' diet at each visit during the study period. Given the lack of evidence on timing of introduction of gluten-free oats for patients with a recent celiac diagnosis, and the potential risks of limiting oats in a gluten-free diet, the results will hopefully lead to better understanding of whether one strategy has a benefit over the other.

In this study, all citizen of Nord-Trøndelag County, Norway, above 18 years of age are invited to participate in a population-based health study, the HUNT study. Blood samples are drawn from the participants and assessed for celiac disease by a serological assay. Celiac disease is a chronic inflammatory disease of the small intestine due to dietary gluten in wheat, barley and rye. The diagnosis will be verified through endoscopic assessment and biopsies from the small intestinal mucosa. The aims of the study are 1) to establish the population-based prevalence of celiac disease; 2) to assess the consequences of the disease from patient reported outcomes, symptoms, deficiencies, and co-morbidity; 3) to study possible risk factors and environmental triggering events; 4) to identify genetic predictors and gene-environmental interactions.

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 is a phase 2b, multicenter, prospective, randomized, double-blind, placebo-controlled, crossover study in symptomatic celiac disease patients attempting a GFD for at least one year prior to screening.

Celiac disease (CD) is a chronic autoimmune condition whose only currently available treatment is a strict, burdensome gluten-free diet (GFD). The current proposal uses a theory-driven empirical approach for optimizing the GFD for teens and their parents by targeting knowledge, behavior, and coping skills through educational and cognitive-behavioral techniques. Integration with telehealth and SMS (short message service; "text") technology for delivering the intervention has the potential to reduce barriers to specialized treatment at both early and later stages of implementation. The proposed research will refine and test a behavioral intervention for teens with CD and their parents using an iterative stakeholder-centered design. It will consist of a small pilot randomized control trial (RCT) (n=96 dyads) that will examine the preliminary efficacy of the intervention and its impact on quality of life and GFD management by targeting self-efficacy, illness identity, and food-related activities. This work has the potential to make a lasting impact on the standards of care and available treatments to optimize CD management in youth and their families.
