Oat Products in the Treatment of Coeliac Disease in Children

Clinical and Nutritional Safety.

In many Northern European countries oat-based products have been used in the dieto-therapy of coeliac disease for many years. The purpose of this study is to evaluate clinical tolerance and liking of gluten-free products containing oatmeal from a specific oat variety (not contaminated with gluten) in a sample of Italian celiac patients in pediatric age.

Probiotics for the Treatment of Irritable Bowel Syndrome in Celiac Patients

IBS in Celiac Desease

Probiotics play an important role in preventing overgrowth of potentially pathogenic bacteria and maintaining the integrity of the gut mucosal barrier. The beneficial effects of probiotics have been previously studied in adult patients with IBS. Clinical studies show that patients meeting the criteria for diagnosis for IBS have greater probability for being affected by celiac desease if compared to controls without IBS. Since one of the causes attributed to the onset of IBS is the modified flora gut, it is interesting to determine the beneficial effects that probiotics may have on gastrointestinal symptoms in celiac disease patients. The goal of the present study is to determine whether oral administration of a probiotic mixture of Lactobacillus plantarum 14D-CECT 4528, Lactobacillus casei, Bifidobacterium breve Bbr8 LMG P-17501, Bifidobacterium breve Bl10 LMG P-17500 and Bifidobacterium animalis under randomized, double-blind, placebo-controlled conditions would improve symptoms of adult celiac patients with IBS.

Assessing Neurocognitive Effects of Gluten Exposure

Celiac DiseaseNeurobehavioral Manifestations

Many patients with celiac disease complain of neurocognitive symptoms such as mental confusion, grogginess, difficulty with concentration and forgetfulness after exposure to gluten. However, there is little data on any possible association between impaired cognitive function and gluten intake in celiac disease. The investigators predict that patients with celiac disease, when exposed to gluten, will experience neurocognitive symptoms such as confusion, forgetfulness and difficulty concentrating. The goals of this study are to determine the prevalence of neurocognitive symptoms after exposure to gluten in patients with celiac disease and to characterize the nature of these symptoms both in terms of their duration and severity.

Prucalopride Prior to Small Bowel Capsule Endoscopy

Gastrointestinal HemorrhageCrohn Disease3 more

Small bowel capsule endoscopy is a test used to investigate for any abnormalities in the small bowel. The small bowel is about 4 meters long. The battery time of the capsule is about 8 hours. During this time the capsule takes pictures as it passes through the small bowel. In about 15-20% of capsule tests the battery expires before the capsule passes through the entire small bowel into the colon. Incomplete tests indicate that a variable portion of small bowel was not visualized. Incomplete tests are associated with potential missing of abnormalities in the portion of small bowel that was not reached. The capsule test may often required to be repeated but the problem of incomplete examination may persist. At present no medication has been approved to increase the rate of complete capsule tests. Prucalopride is a medication that has been approved in Canada and Europe for the treatment of chronic idiopathic constipation. Animal and human studies suggested that prucalopride may enhance the movement of the stomach and the small bowel. A recent presentation at a medical meeting suggested that prucalopride may accelerate the passage of the capsule camera through the small bowel without increasing the chance to miss a lesion in the small bowel. The purpose of this study is to asses if the administration of a single dose of prucalopride is going to decrease the time required by the capsule to move through the small bowel.

Effects of a Dietary Approach to Iron Deficiency in Premenopausal Women Affected by Celiac Disease...

Celiac DiseaseIron Deficiency (Without Anemia)

Anemia and sideropenia are a common effect of untreated celiac disease. In a portion of patients a certain degree of hypoferritinemia persist after the diagnosis, despite a good compliance and clinical response to gluten-free diet. These patients are usually premenopausal women in whom the cyclic menstrual bleeding and the oral iron intake are not balanced. The aim of the study is to compare the efficacy of a pharmacological therapy, frequently not tolerated, and a dietary approach through a iron-rich diet in this subset of patients.

Effect of FODMAP Restriction on Persistent GI-symptoms in Coeliac Patients

Celiac DiseaseIrritable Bowel Syndrome2 more

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.

Celiac Disease and Vitamin Status: Evaluation of the Effect of Supplementation With a Probiotic...

Celiac Disease

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.

Wheat Flour Treatment With Microbial Transglutaminase and Lysine Ethyl Ester: New Frontiers in Celiac...

Celiac Disease

Celiac disease is one of the most common forms of food intolerance (prevalence 1/200). The disease occurs in genetically predisposed individuals after ingestion of foods containing gluten. Celiac patients can suffer from severe malabsorption syndrome, mainly characterized by diarrhea and weight loss. The only therapeutic approach currently recognized is a life-long gluten-free diet. Specific regions of gluten molecule become recognizable by lymphocytes and activate them, due to changes made by tissue transglutaminase. These changes consist in the conversion of specific residues of glutamine into glutamic acid. The consequence is an increased binding affinity between gluten and histocompatibility molecule (HLA-DQ2), localized on the surface of the "antigen presenting cells" (APC); the exposure of the fragments of modified gluten on the surface of APC is a phenomenon that eventually activates T lymphocytes. Recent studies on modified gluten confirmed the hypothesis that it is possible to block the presentation of gluten to lymphocytes by means of lysine ethyl ester binding exclusively to those gluten regions responsible for lymphocyte activation. The enzymatic treatment is performed directly on flour instead of extracted gluten, maintaining the same anti-inflammatory effectiveness. The procedure uses a food-grade enzyme, the microbial transglutaminase (mTGasi) isolated from Streptoverticillium mobarensis, able to catalyze the formation of intermolecular "cross-links" that modify the functional properties of the products. Objective of the study is to validate the ability of the enzyme treatment of wheat flour with mTGasi and lysine ethyl ester to block the toxic effect of gluten in celiac patients.

Assessment of the Effect of Gluten Free Toothpaste on the Ulcerative Events in Children With Celiac...

Gluten Sensitivity

Celiac disease (CD) is the most common genetically based food intolerance in the world, with a prevalence among approximately 1% of the general population (Guandalini & Assiri, 2014). CD is a frequent disorder among Egyptian children, both in the general population and in at-risk groups(Abu-Zekry et al., 2008). It is estimated that the incidence of CD is 3 to13 cases per1000, with a higher prevalence among first-degree relatives of patients with CD.Lifelong adherence to a strict gluten free diet (GFD) remains the only available treatment for patients with CD and typically results in a complete return to health. Nevertheless, gluten is not found only in diet, Gluten is commonly used as a binder in products like medication, cosmetics, oral and skin care, and even children's toys. Gluten is found also in toothpastes and other oral health products and it can be swallowed by mistake and initiate immune response(Anon, n.d.). Unfortunately, there is no gluten free toothpaste available in the Egyptian market and it is very expensive if we bought it from Europe or USA. The tube will cost nearly 10 dolars .As a result, the production and availability of gluten free toothpaste in Egypt has become mandatory.
