Filter by:Patients with irritable bowel syndrome (IBS) often benefit from dietary changes. The effect of a gluten-free diet (GFD) on clinical symptom improvement and psychological well-being will be checked in patients with IBS. In addition, the stimulatory potential of gluten on peripheral blood monocytes will be determined. Responders will be provoked with gluten containing bars or placebo bars to confirm the diagnosis of non-celiac glutensenstitivity.
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.
This study aim to manufacture bread and pasta with an reduced content of gluten and to assess the impact of reducing the daily intake of gluten by 50% in irritable bowel syndrome (IBS) patients. Fungal proteases and selected sourdough lactic acid bacteria will be used for making wheat bread and pasta with a reduced content of gluten (RG) (-50% of traditional products). From a technological point of view, the chemical, structural and sensory features of the RG products approached those of the bread and pasta made with normal level of gluten. The efficacy and safety of new products will be compared to traditional bread and pasta by using a double blind randomized, crossover-controlled trial in IBS patients with persistent gastrointestinal symptoms. Patients will follow two weeks of a GFD diet containing RG bread and pasta and two weeks of GFD diet containing Normal Gluten bread and pasta Symptoms severity will be assessed by Irritable Bowel Syndrome Severity Score (IBS-SS), Visual Analogue Scale (VAS), Hospital Anxiety and Depression Scale (HADS) and Irritable Bowel Syndrome Quality of Life (IBS-QoL).
A randomized, double-blind, placebo-controlled clinical study in non-homozygous human leukocyte antigen (HLA)-DQ.2.5+ adults with celiac disease (CeD).
This study evaluates why people with celiac disease and non-celiac gluten/wheat sensitivity develop rapid onset symptoms within hours of gluten exposure. Half of subjects will be given gluten and half will not.
Patients with non-celiac gluten sensitivity (NCGS) complain about gastrointestinal and extraintestinal symptoms while consuming gluten-containing cereals. The symptoms strictly correlate with ingestion of gluten-containing cereals and disappear quickly under elimination diets. Till now, there are no specific markers to diagnose NCGS. This study aims to determine the effect of a low FODMAP diet (fermentable oligo-, di- and monosaccharides and polyols) and a glutenfree diet on the mucosal immunity, clinical symptoms, and psychological well-being. Furthermore, the influence of the diets on the microbiome will be analyzed.
Recently it has been reported that a consistent percentage of the general population consider themselves to be suffering from problems caused by wheat and/or gluten ingestion, even though they do not have celiac disease or wheat allergy. This clinical condition has been named Non-Celiac Gluten Sensitivity' (NCGS). In a previous paper the investigators suggested the term 'Non-Celiac Wheat Sensitivity' (NCWS), since it is not known what component of wheat causes the symptoms in NCGS patients, and the investigators also showed that these patients had a high frequency of coexistent multiple food hypersensitivity. It is also believed that this condition is worldwide increasing, due to the evolution of wheat breeding (i.e. consumption of wheats with high gluten content), and that "ancient" wheat flour varieties are better tolerated by NCWS patients than the "modern" ones. This effect could be related to a lower immunogenic stimulation of the ancient wheat than the modern ones. The aim of the study is to evaluate the effect of a diet based on ancient grains in a "closed" community (i.e. nuns from enclosed religious order) as regard to 1) main haematochemical parameters and vitamins, 2) intestinal microbiota (bacterial flora), and 3) cytokines production from peripheral blood mononuclear cells (PBMC), before and after the diet period (30 days) with ancient grains.
Background: Celiac disease is an immune-mediated reaction to gluten, presenting with diarrhea, weight loss, abdominal complaints and a range of less common associated neurologic and psychiatric symptoms. Evidence of a link between schizophrenia and celiac disease dates back to 1961. Recent evidence shows that 5.5% (age adjusted) of persons with schizophrenia participating in the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study had a level of antibodies to tTG that is consistent with a diagnosis of celiac disease (compared to 1.1% of the comparison sample). An unexpected finding was that 23.4% (age adjusted) of the CATIE sample had antibodies to gliadin (compared to 2.9% of the comparison sample). It is hypothesized that a gluten free diet in people with schizophrenia who have Celiac disease or gluten sensitivity will have improvement in symptoms and quality of life. Objectives: The aim of this proposed pilot study is to establish the feasibility of a initiating and maintaining a Gluten-free diet in these two groups. For this study The investigators will identify 8 individuals who have positive assays to tTG antibodies and confirmed celiac disease (N=4), or positive assays for anti-gliadin antibodies (N=4). The investigators plan to consent at least 2 subjects from each group and ask them to participate in a two-week open label treatment of a gluten free diet. The groups are; 1. Celiac disease (positive tTG antibody); and 2. Positive assay on Antigliadin antibodies
The idea is to evaluate if the so called "Gluten Sensitivity" is a real clinical entity. Gluten sensitive (GS) persons are defined as those patients, being neither celiac or allergic to weat, who develop symptoms following gluten consumption. This will be achieved by evaluating a global symptom score in GS patients receiving gluten compared to those receiving placebo (primary end point). Symptoms to be evaluated: gastrointestinal (Gastrointestinal Symptom Rating Scale, GSRS); not-gastrointestinal (specifically built evaluation scale); VQV scale, built to evaluate quality of life. Gluten or placebo will be administered daily (10 g) for 15 days; for the 15 days before and 15 after all patients will stay on Gluten Free Diet (GFD). Besides clinical evaluation (each week for 6 weeks), intestinal permeability testing and blood sampling will be requested for the identification of possible markers (serological, gut barrier function, immunological and expression of tight junctions constitutive proteins) that may be of help to differentiate the condition of gluten sensitivity (GS) from that of Celiac Disease (CD)(secondary end point). Inclusion and exclusion criteria for patients enrolling are strictly dependant on the given "Gluten sensitivity" definition. We expect to experience a worsening of gastrointestinal and extra-gastrointestinal symptoms, from hours to days, with an increase in the overall symptom score, above the cut off, in at least 45% of GS subjects enrolled and that have received gluten compared to GS who received placebo.
