Filter by:The primary objective is to obtain stool samples from subjects diagnosed with , and displaying signs and/or symptoms of IBD and/or IBS will be evaluated in this study. Eligible subjects require a diagnostic colonoscopy with possible biopsy and clinical evaluation.
A PROSPECTIVE, double blind, placebo-controlled trial
To the investigators' knowledge, no single long-term prospective observational study has assessed dietary factors, diabetes clinical variables (metabolic control and associated complications), and self -perceived health and wellness in T1D patients (both pediatric and adult) with CD identified by screening (positive/weakly positive serology). The aim of the current study is to observe the short- and long-term outcomes for Type 1 diabetic patients with new serology positive asymptomatic CD.
Prebiotics are known as substances affecting beneficially the organism by restoring the intestinal microbiota balance, stabilizing the intestinal barrier and modulating the endocrine and immune functions. In many persons suffering from celiac disease (CD), despite a gluten-free diet (GFD), an impaired intestinal barrier functionality, accompanied by altered intestinal microbiota and ongoing intestinal inflammation is observed. For these reasons, prebiotic could be a promising and low-risk adjuvant in the dietetic management of CD. It was hypothesize that prebiotic preparation Synergy 1 consumed by CD children as a supplement of a GFD will affect beneficial the intestinal permeability and intestinal microbiota without side effects.
Study Aims: To analyze stool specimens to test and validate the CalproLab assay against the predicate PhiCal in order to determine performance characteristics. And to correlate Calpro levels to the gut microbiome composition.
To study the correlation between simvastatin metabolism by the enterocyte and the histologic state of the intestine in treated celiac disease.
This study assessed the effect of a nutrition support product on quality of life in adults with compromised gut function and malabsorption.
The subject Novel Motorized Spiral Enteroscope (NMSE) represents a new technology which offers all of the advantageous options of spiral enteroscopy with a faster and less invasive approach. The system is similar to other currently marketed endoscopes in that it incorporates a flexible insertion tube, light source, digital imaging, and channels for passing accessories for sample collection or therapeutic interventions. The NMSE system is unique in that it incorporates a user-controlled motor contained in the endoscope's handle to rotate a spiral cuff located on the endoscope's insertion tube. Rotation of this cuff, which has soft spiral-shaped "fins", pleats the small bowel on to the endoscope's insertion tube, thereby allowing rapid and atraumatic access deep into the small bowel. The system also includes a display monitor, a motor control unit, device to display measured motor current and signal torque, and a set of foot pedals. Motorization of the Spiral Enteroscope and limitation of rotation to a short cuff instead of a long overtube promise to accelerate the procedure, to facilitate insertion and to improve maneuvering the instrument in comparison to conventional spiral enteroscopy
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.
