Gluten Challenge Study in Celiac Disease Participants (MK-0000-402)
This is a gluten challenge study to characterize peripheral blood and intestinal gluten specific cluster of differentiation 4 glycoprotein (CD4+) thymus lymphocyte (T cell) subsets in participants with Celiac Disease
Gluten-free Oats and Gastrointestinal Health in Coeliac Disease, Part 1
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...
Imaging the Duodenum Using an Optical Frequency Domain Imaging OFDI Capsule
The study is being done to assess the tolerability and feasibility of a tethered OFDI capsule to image the duodenum. A total of 24 subjects will be asked to swallow the tethered capsule, while they are awake and unsedated and ask for their feedback. Images will be taken using the OFDI system while the capsule travels from the esophagus into the stomach and into the duodenum.
Improved Diagnostics of Celiac Disease in Children
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.
Inflammatory Back Pain and Gluten Free Diet
Articular involvement is the most frequent extra-intestinal manifestation of inflammatory bowel diseases (IBD). IBD-related spondyloarthropathy is mainly characterised by axial involvement (including inflammatory back pain, isolated sacroiliitis and ankylosing spondylitis) but may also be associated with peripheral symptoms (i.e peripheral arthritis, dactylitis and enthesopathy, such as Achilles tendinitis, plantar fasciitis, and chest wall pain). In particular, inflammatory back pain (IBP) is characterised by an insidious onset, improves after exercise but not with rest, and is associated with morning stiffness. Up to now, several criteria...
Intestinal Fatty Acid-binding Protein (I-FABP) Levels in Pediatric Celiac Patients
A prospective, longitudinal study meant to compare blood levels of I-FABP in pediatric celiac patients during diagnosis to levels under gluten free diet, it's correlation with traditional serology testing and questionnaire regarding patient responsiveness to the gluten free diet, and in comparison to a control group.
Intraoperative Versus CT Guided Celiac Plexus Neurolysis in Unresectable Pancreatic Cancer
Many studies had stated that the coeliac plexus neurolysis (CPN) is a safe and effective treatment method of pain associated with pancreatic cancer. The neurolytic injectate is usually alcohol 50-100%; however, phenol >5% is also possible to use. Nowadays, there are several techniques to access the coeliac plexus (per cutaneous using fluoroscopy or computed tomographic imaging (CT), surgical and endoscopic ultrasound). However, the percutaneous computed tomography guided technique is the gold standard technique, it has multiple drawbacks as availability and cost of imaging modality, exposure to radiation and multiple complications.Surgical...
Irritable Bowel Syndrome and the Identification of Wheat or Gluten Sensitivity
The aim of our study will be to establish in how many subjects with gastrointestinal symptoms and previous diagnosis of irritable bowel syndrome (IBS), the clinical picture is attributable to non celiac gluten sensitivity (NCGS) or fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) intolerance. For this purpose, all subjects with IBS will take a low FODMAPs diet, which implies the absence of cereals and consequently of gluten, and those presenting symptom improvement during this dietary treatment, will be exposed to a double-blind gluten or placebo challenge, to make a diagnosis of NCGS.
Latiglutenase as a Treatment for Celiac Disease
Single Center, Randomized, Double-Blind, Placebo Controlled, Gluten Challenge Trial in Patients with Well-Controlled Celiac Disease
OptiCal Study -Optimizing Fecal Calprotectin Monitoring: a Clinical Study Comparing CalproLab Against PhiCal and Evaluating Its Association With the Gut Microbiome
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.
