B HLMANN fCAL ELISA - Aid in Differentiation of IBD From IBS

The purpose of this study is to confirm the sensitivity and specificity of the BÜHLMANN fCAL™ ELISA as an aid in diagnosis to differentiate between Inflammatory Bowel Disease (IBD; Crohn's Disease (CD), Ulcerative Colitis (UC), or indeterminate colitis) and Irritable Bowel Syndrome (IBS). To estimate the predictive value of a ...

Phase N/A

Experience Sampling Method for Symptom Assessment in Irritable Bowel Syndrome

Reliable patient reported outcome measures (PROM's) for symptom assessment in irritable bowel syndrome are essential in order to investigate natural disease course and potential treatment options aimed at symptom improvement, since biological markers are currently unavailable. Currently used symptom assessment methods, i.e. end-of-day or end-of-week questionnaires, have considerable limitations. The ...

Phase N/A

Assessment of Colonic Permeability by Confocal Laser Endomicroscopy

Increased intestinal permeability has been shown significant in many gastrointestinal diseases, including inflammatory bowel disease and recently irritable bowel syndrome. The conventional test methods of permeability is sugar absorption test which is neither reliable and practical. Confocal laser endomicrosopy is a newly developed device which allows in vivo and real ...

Phase N/A

Maastricht IBS Cohort

Aim of the present study is to set up a large cohort of IBS patients in order to identify different disease characteristics as well as aetiological and pathophysiological factors in (sub)groups of patients with this heterogeneous disorder. Various phenotypical and genotypical markers will be evaluated. For this purpose, blood and ...

Phase N/A

Brain-Gut Interactions in Overweight and Normal Weight Patients With Chronic Abdominal Pain

The objective of this natural history study is to assess the specific gastrointestinal (GI) symptoms and pathophysiology of chronic abdominal pain of unknown origin at the molecular level. This research will test the hypothesis that chronic abdominal pain of unknown etiology has an inflammatory mechanism. Although increased body weight may ...

Phase N/A

Immunological Profiles in Inflammatory Bowel Disease

Rationale: Inflammatory Bowel Diseases (IBD) is a heterogeneous group of diseases regarding clinical presentation, disease course and treatment response. Pathogenesis is complex and multifactorial, based on interactions between genetic and environmental factors, gut microbiota and the immune system, leading to intestinal inflammation. As the immune reaction itself causes the intestinal ...

Phase N/A

Ileocecal Sphincter Reflex by Cecal Distension During Colonoscopy

This is an outpatient study. There will be no requirement to stay overnight in the hospital. The research will be conducted in the gastroenterology section of the department of Medicine in North shore university hospital and in North shore long island Jewish medical center. Both these hospitals are tertiary care ...

IBDSL Biobank Project. Molecular Markers for Diagnosis and Therapy Response in IBD.

Background: Inflammatory Bowel Disease (IBD), encompassing Crohn's Disease (CD) and Ulcerative Colitis (UC), is a chronic disabling condition of the intestine. Most patients experience sequences of exacerbation in which quality of life is often impaired. Also society endures heavily, as IBD healthcare costs are estimated at 4.6-5.6 billion euros per ...

Phase N/A

ALPCO Calprotectin ELISA - Measurement of Calprotectin Levels in Human Stool

The ALPCO Calprotectin ELISA is an in vitro diagnostic test intended to quantitatively measure concentrations of fecal calprotectin in human stool samples. Calprotectin is a protein biomarker of mucosal inflammation. Measurement of calprotectin can aid in the diagnosis of Inflammatory Bowel Diseases (IBD), specifically Crohn's Disease (CD) and Ulcerative Colitis ...
