Filter by:The purpose of this study is to determine whether inflammatory bowel disease in children involve the respiratory tract as expressed by increased levels of the Fraction of exhaled Nitric Oxide (FeNO) and spirometry.
The main objective of this study is to determine the role of epithelial cell homeostasis in the pathogenesis of intestinal diseases. Background: Alterations in intestinal barrier function may play a significant role in the pathogenesis of chronic intestinal diseases such as inflammatory bowel disease (IBD). The intestinal epithelium functions as a barrier to the luminal contents, thereby preventing undesirable solutes, micro-organisms and other luminal antigens from entering the body. Confocal endomicroscopy has recently been shown that increased epithelial cell shedding may contribute to increased intestinal permeability, at least locally. In our study, we want to determine the contribution of epithelial cell shedding to intestinal permeability in vivo in patients with inflammatory bowel disease compared to controls. Scope: In inflammatory bowel disease patients and controls (patients undergoing endoscopy for other indications). Methods: We will perform confocal endoscopy during the patient's endoscopic procedure. Procedure: The patient will receive intravenous fluorescein, followed by confocal imaging of the gastrointestinal tissue. The images are captured on the computer. The proposed study will provide important insights into epithelial cell shedding as a contributor to altered intestinal permeability.
To show that prevalence of inflammation of the small bowel in patients with anorectal disease is under-diagnosed based on colonoscopy ileoscopy alone.
The objective of this NIH-specific substudy is immunologic monitoring of cytokine and immune cell responses in subjects undergoing treatment with AIN457 (human monoclonal anti-human interleukin-17A) for moderate to severe Crohn's disease. Recent data suggests that interleukin-17 (IL-17) is an important mediator of inflammation in certain animal models of Crohn's disease, and treatment aimed at blocking the IL-23-IL-17 axis can ameliorate the inflammatory changes. In addition, elevated expression of IL-l7 has been found in the gut tissue of patients with active Crohn's disease. This substudy will measure changes in cytokine production, relevant RNA expression, and immune cell populations (in the periphery and lamina propria) for correlation with clinical outcomes in order to explore the mechanisms of therapeutic response.
The purpose of this study is to examine the effects of different environmental factors on immune cells in patients with IBD.
A Multicenter National Prospective Study of Pregnancy and Neonatal Outcomes in Women with Inflammatory Bowel Disease study is being conducted at the University of California San Francisco and 30 other sites around the United States who are part of the CCFA Clinical Alliance. The aim of this study is to determine the effect of medication use and disease activity on the outcome of pregnancy among women with IBD up to 18 years from birth.
This is a single center, open label forced dose titration study designed to determine the tolerability of curcumin in pediatric patients with inflammatory bowel disease (IBD). This study will provide initial tolerability and safety data in pediatric patients with IBD. Twenty patients with IBD in remission or with mild disease (score <34 on PUCAI or score <30 on the PCDAI) on sulfasalazine or mesalamine aged 8 to 18 years will be enrolled into this study. Each patient will participate in the study for nine weeks. From this study an appropriate dosage will be determined to proceed with a double blinded placebo controlled study.
The purpose of this study is to evaluate the efficacy of confocal laser endomicroscopy in assessment of colonic permeability against conventional sugar absorption test.
Healthy Normal Single Ascending Dose and Crohn's patient Multiple Ascending Dose
Fatty liver is known to be one of the most frequent liver pathologies in IBD patients (35-40%). Despite this fact, there are only few publications that evaluated the prevalence of fatty liver in IBD patients. Moreover, the pathogenesis of this phenomenon in IBD has not been widely investigated. The paradox of lean patients and fatty liver can be explained by high use of steroids, by rapid weight loss, and by the abundance of TNFα cytokine in IBD patients that causes insulin resistance. The aim of the study: To evaluate the frequency of fatty liver in a cohort of IBD patients and to learn its risk factors. Methods: One hundred consecutive IBD patients treated at the Tel Aviv Sourasky Medical Center will be recruited. Patients will fill up a questionnaire regarding their disease, demographic data, other co-morbidities and medications and risk factors for metabolic syndrome. Each patient will undergo blood examinations in order to assess inflammation, and metabolic status. Fatty liver will be assessed by liver ultra-sonography.
