View clinical trials related to Celiac Disease.
Filter by:Celiac disease (CD) is an immune-mediated systemic disease that is elicited by consumption of gluten and related prolamines in genetically susceptible individuals. Not only genetic but also environmental factors play an important role in CD pathogenesis. CD patients have imbalance in the gut microbiota, they have reduced number of Bididobacterium species in feces and biopsies. Up till now, only effective treatment for CD is life long adherence to gluten free diet. If gluten free diet is not strict that leads over the years to complications of disease, such as autoimmune diseases, psychiatric diseases, osteoporosis etc. That may be caused by continuous recirculation of activated immune cells between the inflamed organ and the periphery. To avoid complications of disease in long term the investigators want to test specific probiotic bacteria from Bifidobacteria genus, that has has been in vitro studies recognized as anti-inflammatory. Hypothesis 1. Children with celiac disease on gluten free diet have a higher level of pro-inflammatory cytokine (TNF-alpha) and anti-inflammatory cytokine (IL-10) in comparison with healthy controls. 2. 3 months after daily probiotic consumption TNF-alpha level decrease and IL-10 level increase. In the investigators research will be selected 70 children, age from 2 to 18 years, divided in different groups: 1. Group: 25 children with celiac disease on GFD for at least 3 months and will receive probiotic for 3 months. 2. Group: 25 children with celiac disease on GFD for at least 3 months and will receive placebo for 3 months. 3. Group: 20 healthy children
Celiac disease (CD) is a chronic immune-mediated disorder that occurs in genetically predisposed populations. Patients affected by the disease may be asymptomatic or manifest classic malabsorption symptoms of diarrhea, steatorrhea, abdominal pain, and weight loss after gluten ingestion (and related derivatives found in other grains). Diagnosis and screening begin with the use of serologic tests, i.e. IgA anti-tissue transglutaminase (tTG) and IgA anti-endomysial antibodies (EmA). Duodenal biopsy, still considered by many as the criterion necessary for diagnosis, demonstrates the pathologic findings of small intestinal villous atrophy, crypt hyperplasia, and intraepithelial lymphocytosis that occur on exposure to dietary gluten. Genetic tests, revealing permissive haplotypes, may be helpful in identifying susceptible individuals. CD diagnosis is still anchored to the criteria established by the European Society of Pediatric Gastroenterology Hepatology and Nutrition in 1990. These require the mandatory presence of (a) villous atrophy with crypt hyperplasia and increased intraepithelial lymphocytes (IELs) count when the patient is eating gluten, and (b) a full clinical remission after elimination of gluten from the diet. As a consequence, patients with minimal or no intestinal histology lesions pose a considerable problem, as serum anti-tTG and EmA are known to be often negative, or weakly positive, in patients with CD with mild intestinal damage. The investigators, in 2002, measured anti-tTG antibody in the culture medium of intestinal biopsy specimens from patients with suspected CD and evaluated the relationship between antibody production and severity of intestinal mucosal damage, and demonstrated that anti-tTG assay of the culture medium of biopsy specimens can improve the accuracy of CD diagnosis in patients negative for serum antibodies. The same investigators, in 2011, evaluated the diagnostic accuracy of EmA assay in the culture medium of intestinal biopsies for CD diagnosis and demonstrated that EmA assay in the culture medium had a higher sensitivity and specificity than serum EmA and anti-tTG assay. The present study is performed to investigate the clinical usefulness of the in vitro production of EmA in CD diagnosis in a large number of consecutive adult patients with suspected CD and weakly positive [e.g. 2-3xN] serum anti-tTG.
Preliminary studies on safety profile of Triticum Monococcum (Tm, a variety of Ancient Wheat) have provided conflicting results with some in vitro and ex vivo studies consistent with non toxicity and other suggestive of toxicity. We recently reported results of a single administration of 2.5 grams of Tm in 12 Celiacs in remission on Gluten Free Diet (GFD), while assessing symptoms and changes of intestinal permeability. Although results of intestinal permeability were inconclusive Tm, but not other type of gluten, was clinically well tolerated. The aim of the present study was to assess safety of 60 days of administration of Tm (100 grams of water biscuits per day accounting for about 6 grams of gluten from Tm) as judged on clinical, serological and histological parameters in Celiac Disease patients on remission after 1 year of GFD.
The most frequent diseases caused by wheat ingestion are T cell-mediated disorders, i.e. celiac disease and immunoglobulin E (IgE)-mediated allergic reactions. However, besides celiac disease and wheat allergy, there are cases of gluten reactions in which neither autoimmune nor IgE-mediated allergic mechanisms are involved. These are generally defined as GS or Not-celiac wheat sensitivity (NCWS). Typically, NCWS diagnosis is made by exclusion, and an elimination diet and an "open challenge" (i.e., the monitored reintroduction of gluten-containing foods) are most often used to evaluate whether health improves or worsen with the elimination or reintroduction of gluten in the diet, respectively. In some circumstances, it is very difficult to distinguish between NCWS and celiac disease. The presence of positive celiac disease specific serum antibodies (anti-tissue transglutaminase (anti-tTG), and anti-endomysium (EmAs) antibodies) is of paramount importance to pose the diagnosis. However, it is well known that the frequency of a positive serology is dependent by the severity of the intestinal damage. Consequently, patients with less severe histology damage (Marsh 1) can have negative serum antibodies. Previous studies had demonstrated that EmAs are produced by the intestinal lymphocytes and previous data from our group showed that EmAs assay in the culture medium of the intestinal biopsies has higher diagnostic accuracy than serum EmAs in diagnosis. Therefore, the aims of our study are to evaluate the clinical-serologic-histology course of NCWS patients, showing positive EmAs assay in the culture medium of the duodenal biopsies at the time of the first evaluation, and the adherence to a gluten-free diet in NCWS patients after a previous full evaluation and a NCWS diagnosis based on double-blinded placebo-controlled (DBPC) challenge.
Celiac disease (CD) and eosinophilic esophagitis (EE) are distinct diseases of the gastrointestinal tract with specific clinico-pathological characteristics. In recent years, in the literature, several children who underwent upper gastrointestinal endoscopy for suspected CD, which was confirmed histologically, were also found to have coexistent EE. There are reports of coexistent CD and EE. We would like to see the prevalence of EE in children with CD and the prevalence of CD in children with EE in our population, and to do so would like to review medical records. Our objectives are to determine if children with celiac disease have a high prevalence of eosinophilic esophagitis.and to determine if children with eosinophilic esophagitis have increased risk of developing celiac disease.
The main purpose of this study is to improve the diagnostics of celiac disease and reduce the need for invasive endoscopic studies in children. Further, the investigators aim to investigate the natural history and risk of complications in children with celiac disease or gluten sensitivity and to create a large scientific database.
The purpose of this study is to evaluate the safety of different amounts of BL-7010 in single oral administration and in repeated oral administration to well-controlled celiac patients. Another purpose is to evaluate if BL-7010 is absorbed by the body or not.
The purpose of this study is to determine whether the immune response causing celiac disease is related to the autoimmune response causing type-1 diabetes.
We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We make it easy for patients to contribute to research for medical conditions that matter most to them, regardless of their location or ability to travel.
The main purpose of this study is to see how cells taken from the lining of the intestine behave in the laboratory with exposure to gluten and other substances that act on the immune system. The cells lining the intestine of a person with celiac disease should be different than a person without celiac disease. The study doctors would like to see how the cells react after coming in contact with gluten and if substances that act on the immune system can prevent gluten related inflammation. Examples of these substances include steroids. The cells should produce chemicals of their own in response to the gluten. These other chemicals will be measured and the results compared between those with: - celiac disease that does not respond to a gluten-free diet (refractory celiac disease) - celiac disease which is controlled by a gluten-free diet - uncontrolled celiac disease (either newly diagnosed with celiac disease or not on a gluten-free diet - gluten-sensitivity - disorders other than celiac disease.
