Filter by:Sucrosomial iron (Sideral® Forte) is a preparation of ferric pyrophosphate conveyed within a phospholipid membrane associated with ascorbic acid, is a new-generation oral iron which shows a high gastrointestinal absorption and high bioavailability with a low incidence of side effects due to lack of any direct contact with intestinal mucosa. In comparison with the other standard oral iron preparations, sucrosomial iron seems to be a promising new strategy of iron replacement in CD patients.
Irritable Bowel syndrome (IBS) is a very frequent condition in children. Its management is difficult, often resulting in a persistence of chronical abdominal pain. In adults, many patients affected by IBS improve under a gluten-free diet, even in the absence of Celiac Disease (CD) or wheat allergy. This condition is called Non Coeliac Gluten Sensitivity (NCGS). However, it is still not clear how to diagnose and manage NCGS, and the pathophysiological mechanisms also remain elusive. The aim of this study is to determine if NCGS exists in children with IBS and to identify the clinical, serological, and histological characteristics, which could distinguish patients with NCGS from conventional IBS and CD patients. This is a prospective cohort study in a population of children affected by a moderate to severe IBS for more than 6 months. All children had a Gluten Free Diet (GFD) for 6 weeks. Then, children who improved under GFD were randomized in two groups for a double-blind placebo-controled trial. One group had a reintroduction of gluten followed by a wash-out period, then a placebo reintroduction, whereas the other group had the placebo first, then the wash-out and the gluten reintroduction.
The aim of this study is to assess the clinical utility of the whole blood transglutaminase-based rapid test against current serological tests and the gold standard of duodenal biopsy. The investigators will recruit patients (n=1000) from the endoscopy department at the Royal Hallamshire Hospital, Sheffield, United Kingdom (UK). The patients recruited for this study will already have been referred for a consultation and gastroscopy. In addition, these patients will already have been serologically tested for IgA TTG, EMA and a total IgA immunoglobulin level (as per normal clinical practice). All duodenal biopsy specimens will be fixed in buffered formalin and embedded in paraffin wax. Standard, 3μm thick sections at three levels will be stained with haematoxylin and eosin and reported routinely. Additionally, biopsies demonstrating increased intraepithelial lymphocytes only (changes compatible with but not diagnostic of coeliac disease) will be stained with KiRAS or CD4/CD8 which are markers for coeliac disease.
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.
The investigators will perform prospective observational multicenter study which includes children with suspicion of CD who referred to gastroscopy and intestinal biopsies (study group) and children without suspicion of CD who underwent gastroscopy for other reasons. The investigators will compare sensitivity, specificity and predictive values of several serological kits of TG2 (tissue transglutaminase) (Bioplex 2200, Bioflash, Phadia 250, Liason-XL, Orgentec Alergia and Eurospital) compared with definitive diagnosis of CD according to histological findings.
The research aims to investigate the effects of gluten-free oats to the gastrointestinal health in celiac disease patients and healthy subjects. The effects of gluten-free oats on the several intestinal parameters, on the composition of the gut microbiota as well as on the metabolic profile of celiac patients and healthy controls will be studied. The study is divided into two parts. Part 1 will be conducted as a double-blind, randomized and placebo-controlled cross-over study. Healthy subjects will be recruited to the study. The aim is to recruit 15 participants for the part 1. The study will be conducted with a cross-over setting, where the subjects will go through exposure meals and SmartPill ingestion three times (two different oat products and placebo) in a randomized order. The study meals are identical in appearance and fiber content. After consuming the meal subjects will ingest the SmartPill capsule, which will send data on intestinal pH, pressure and temperature to the external portable device. Before and during the passage of capsule the subjects will fill a symptom and food diary. The capsule will exit the body in 1 to 3 days and the data collected by the external device will be collected and analyzed. Before the oat/placebo exposure the subjects will give a fecal and a blood sample. In addition, 36 hours urine samples will be collected. In part 2 celiac disease patients, non-celiac gluten sensitive subjects and healthy controls will be recruited and they will be divided into four groups: oat-avoiding celiacs (1), oat-consuming celiacs (2), non-celiac gluten sensitive subjects (3) and healthy controls (4). Recruiting aim for each group is 15 subjects. In addition to dietary data, a blood, and a fecal sample will be collected from the subjects. The gut microbiota will be analyzed from the fecal samples. The metabolic products will be analyzed from the fecal, urine and blood samples. The gut microbiota composition will be analyzed with next-generation DNA sequencing techniques.

This trial is a Phase 1b multicentre, multinational, randomized, double-blind with single-blind arm and open label extension phase, placebo controlled, clinical trial evaluating the safety and predictability of an escalating gluten consumption to activate Coeliac Disease (CeD) in (a) a small cohort of people with diet-managed CeD treated with a placebo (n=10), and in (b) cohorts following low (L3-10; n=40) and medium (L3-20; n=10) dose hookworm inocula. The investigators 4 aims for the study are: Aim 1: Undertake a multiple-phase and escalating gluten challenge assessing safety to gluten exposure in hookworm-naïve and hookworm-infected people with CeD. Aim 2: This phase Ib study recognizes that the evidence supporting this novel intervention is rudimentary and addresses amongst others the following questions: (a) The importance of L3 dose on Participant health, and (b) the importance of L3 dose on the safety of escalating gluten challenge and (c) the need for a comparator group should a phase II trial be warranted. Aim 3: Examine the changes in intestinal T cell responses induced by hookworm infection and gluten exposure. Aim 4: Assess the impact of hookworm infection and purified hookworm-derived proteins on gluten peptide-specific immune responses ex vivo.
The study assessed whether compete healing of duodenal mucosa in celiac patients with persistent Marsh I-II lesion after 1 year of gluten free diet (GFD): - could be achieved by adoption of a diet based exclusively on naturally gluten free products, with the elimination of commercially available processed food (GCED, Gluten Contamination Elimination Diet); - may depend upon time of exposure to GFD. Investigators studied two cohorts of celiac patients, both on GFD, for at least one year: - cohort A: patients re-biopsied after three months on GCED; - cohort B: patients re-biopsied after a minimum of further two years on standard GFD.
Treatment for celiac disease (CD) is a lifelong strict gluten-free diet (GFD). Patients should be followed-up with dietary interviews and serologic tests for CD markers to ensure adherence to the diet. However, none of these methods offer an accurate measure of dietary compliance. Our aim was to evaluate the measurement of gluten immunogenic peptides (GIP) in stools as a marker of GFD adherence in CD patients and compare it with traditional methods of GFD monitoring. We performed a prospective, non-randomized, multicentre study including 188 CD patients on a GFD and 73 healthy controls on a gluten-containing diet. Subjects were given a dietary questionnaire and fecal GIP quantified by ELISA (iVYLISA GIP-S kit). Serological anti-tissue transglutaminase (anti-tTG) IgA and anti-deamidated gliadin peptide (anti-DGP) IgA antibodies were measured simultaneously.
