Background of Different Phenotypes of Coeliac Disease
Celiac DiseaseDermatitis HerpetiformisThe main purpose of this study is to investigate genetic, serological, immunological and microbiata diversities between different coeliac disease phenotypes and to discover applicable prognostic markers for specific phenotypes.
Rapid Technique for the Detection of Intestinal Anti-transglutaminase Antibodies
Coeliac DiseaseIntestinal Celiac Disease (CD)-antibodies have been described as the best marker to reveal progression toward villous atrophy and could become the diagnostic marker to make prompt diagnosis in the wide clinical spectrum of CD reducing the delay in diagnosis and treatment. The introduction of either anti-endomysial antibodies (EMA) assay or rapid anti-Transglutaminase 2 (TG2) test on supernatant of mechanically lysed biopsy samples in the clinical practice would improve the diagnosis of CD, especially in clinically challenging scenarios. The availability of an accurate test for identifying intestinal CD-antibodies that do not need the culture of intestinal biopsy is less expensive, less time consuming and easier to perform would facilitate the implementation of such technology outside research laboratories, and enable the diagnosis of CD at the end of Gastrointestinal Endoscopy (GIE).
Assessing the Histological Quality of Biopsy Samples Obtained With Multibite Forceps
Helicobacter Pylori InfectionCeliac DiseaseBiopsies are routinely taken during endoscopy and colonoscopy in order to facilitate histological analysis of various disease processes. The current practice of obtaining biopsies involves taking a maximum of two biopsies at a single time (ie. with a single pass). When investigating certain diseases, such as celiac disease, there is a need to obtain several biopsies (sometimes greater than 6) and the current practice of taking one to two biopsies at a time can lengthen endoscopy time. This study investigates a new approved multiple bite forceps that has the ability to retrieve six biopsies during a single pass which could reduce endoscopy time and improve diagnostic yield. This study will assess the histological quality of multiple biopsies when taken with the multiple bite forceps compared to the standard double bite forceps. This multiple bite forcep is approved for clinical use in Canada.

Mass Screening for the Early Detection of Patients With Celiac Disease.
Celiac DiseaseThe use of a home rapid test for the detection of both gluten immunogenic peptides (GIP) in urine and immunoglobulin A (IgA) anti tissue transglutaminase (anti-tTG) antibodies in blood may contribute to the early detection of volunteers who suffer celiac disease (CD), a highly under-diagnosed disorder. Patients with positive results could inform their doctors in order to accelerate the diagnosis, contribute to symptoms control and improve their quality of life. This observational, cross-sectional study with no interventions applied in subjects consists on a single group of volunteers between 2 and 18 years old. They will be given an informed consent which must be signed by them or their parents/legal guardians, a Celiac Symptoms Index (CSI) questionnaire and the sample collection material required on the testing day. Urine samples will be collected and analysed in situ or alternatively they will be stored and analyzed after at the laboratory. Blood samples will be collected and analyzed in situ the testing day. The main outcome is to determine the prevalence of CD through mass screening within the pediatric and adolescent population in order to provide an early diagnosis and avoid long-term consequences which are suffered by untreated patients. As an international innovation, misdiagnosis (false negatives) because of an insufficient gluten intake are expected to be detected, thus the use of GIP detection in urine will confirm gluten ingestion at the diagnosis. Volunteers with a confirmed diagnosis of CD could be monitored by their doctors to corroborate whether a gluten-free diet improves their quality of life.
The Living With a Long-Term Condition Study
AsthmaAtrial Fibrillation43 morePsychological distress (anxiety and depression) is common in and experienced differently by people living with long-term health conditions (LTCs). Being able to measure whether psychological distress is related to living with a LTC would allow researchers and clinicians to provide interventions specifically tailored to the challenges of living with a LTC and therefore provide the most appropriate support for these patients. Such a measure would also be useful in research to identify the presence of illness-related distress in different patient groups. This project will therefore create a new measure of illness-related distress that has applications for both research and clinical practice. This will involve the psychometric validation of the new illness-related distress measure to test how valid and reliable the measure is. The aim of the project is to provide initial validation of the Illness Related Distress Scale in a community sample, recruited through online platforms. The objective of the study is to gather initial validity and reliability data for the scale.
Pathogenic Study of Adult Immune Enteropathies
Celiac DiseaseAutoimmune Enteropathy1 moreThe study focuses the mechanisms underlying the loss of intestinal homeostasis in celiac disease, refractory celiac disease and other immune diseases such as monogenic enteropathy, inflammatory bowel diseases or drug induced intestinal diseases. Mechanisms of transformation of lymphocytes leading to onset of lymphomatous complications of immune enteropathies will be investigated. Mechanisms of loss of hepatic lymphocytic homeostasis will also be assessed in liver associated diseases.
Celiac Disease Database
Celiac DiseaseThe focus of this study is to create a database containing information about patients with celiac disease. This database will allow us to examine clinical and epidemiologic features of the University of Chicago Medical Center patient population. We have the largest population of patients with celiac disease in the mid-West and as such this study using information gathered from our database can greatly contribute to our current understanding of this disease.

FREQUENCY OF FIBROMYALGIA IN PATIENTS WITH CELIAC DISEASE
Celiac DiseaseFibromyalgia950 / 5.000 Çeviri sonuçları Celiac disease is an autoimmune proximal small bowel disease that develops as a persistent intolerance to gluten-like gluten in cereals, mainly wheat gluten and other cereal proteins such as barley, rye, and oats in genetically susceptible individuals. Fibromyalgia syndrome (FMS) is a chronic musculoskeletal disease characterized by chronic widespread body pain, fatigue, morning stiffness, subjective swelling, sleep disturbance, intestinal problems, multiple somatic and cognitive problems, especially in the back, neck, shoulders and hips. In terms of intestinal symptoms, very similar findings can be observed between celiac disease and fibromyalgia. For this reason, the presence of celiac disease in FMS patients has been investigated in many studies and its frequency has been found to be high. However, the frequency of FMS in patients with celiac disease is not clear, and an overlooked diagnosis of fibromyalgia may leave many symptoms untreated.
