Filter by:The study aims to: 1. To determine the relationship between inflammatory activities and epithelial gaps in IBD by CLE and evaluate epithelial gaps healing via dexamethasone treatment. 2. To demonstrated the alteration of local barrier function in IBD using CLE.
The purpose of this study is to evaluate the incidence, prevalence, clinical characteristics and prognosis of Crohn's disease and ulcerative colitis over time in a district of Seoul, Korea.
Alterations in normal serotonin (5-hydroxytryptamine;5-HT) signaling have been reported in ulcerative colitis (UC) and Crohn's disease (CD). Studies report an increase in enterochromaffin (EC) cell, main source of 5-HT in the gut, numbers in CD and UC patients. Up-regulated expression of mucosal Tryptophan hydroxylase (TPH)-1, catalytic enzyme in 5-HT production, messenger RNA (mRNA) have been found in CD patients in remission who are suffering the irritable bowel syndrome (IBS)-like symptoms. Alterations in normal 5-HT signaling has also been reported in animal models of inflammatory bowel disease (IBD). Thus, the aim of the proposed research project will be to study the alterations in 5-HT signalling accompanying GI inflammatory conditions, such as IBD.
The study aims to: 1. Determine whether the density of epithelial gaps in terminal ileum of patients with irritable bowel syndrome (IBS) is different from that in inflammatory bowel disease (IBD) patients and normal controls by confocal laser endomicroscopy (CLE). 2. Evaluate the relationship between the density of epithelial gaps and IBS subtypes, and visceral hypersensitivity.
Conventional multi-port laparoscopic surgery (CL) is now a standard approach to colorectal resections, due to it's short-term benefits over conventional open surgery. In recent years, several studies have demonstrated that - in suitable patients - single-port access surgery (SPA) has similar clinical outcome compared to CL, with additional cosmetic benefits. It remains, however, unclear whether the trauma of surgery is also less for SPA compared to CL. In this study, the investigators aim to randomise patients who are deemed suitable for SPA surgery to either SPA approach, or CL; in addition to clinical outcomes including length of operating time, post-operative pain scores, complications, quality of life indicators and cosmetic appearance, the investigators aim to compare the physiological response to trauma through biochemical markers (including C-reactive protein, White Blood Cell count) and cytokine expression (i.e. Interleukins IL-6 and IL-8). Patients will be analysed according to intention-to-treat analysis, with 25 patients in the SPA and 25 patients in the CL group. The patients will be operated by surgeons proficient in both CL and SPA surgery, and followed-up for the duration of their hospitalisation as well as at their routine out-patient visits, using questionnaires.
Under normal conditions intestinal mucosa presents a baseline "physiological inflammation" caused by a controlled immune response that eliminates offending dietary and microbial antigens. This inflammation disappears once the cause is eradicated. In case of inappropriate immunological response, the inflammation becomes chronic and harmful, resulting in anatomical and functional abnormalities, namely inflammatory bowel disease (IBD). Although it is critical for the IBD patients to undergo early diagnosis and management before the development of severe complications, but as IBD has vague and non-pathognomonic clinical features, the clinician is usually mislead into late suspicion and detection of IBD. Diagnosis traditionally depended on a combination of pathologic evaluation together with the histological, clinical, radiological, endoscopic, surgical, laboratory (serological) features. Recently, serological markers were identified and became of special interest as they do not only detect the occurrence of IBD but also the potential of its development and may be used as prognostic tools. More recently, stool markers were detected and used for diagnosis. Up to now, the market is still lacking a definitive, simple and non-invasive diagnostic tool. Saliva can present an alternative form of body fluids that simplify diagnostic procedures. Our hypothesis is that IBD patients have special salivary biomarkers that may be identified through salivary analysis, where later on a simple non-invasive test can be applied in the form of an easy-to-use kit, being available at the clinician's clinic for the establishment of an immediate and early diagnosis of the destructive inflammatory bowel disease.
The study aims at studying the outcomes of a protocol-based handling of newly diagnosed Inflammatory bowel disease ( IBD ) patients within a defined uptake area in Norway. It is a descriptive study and no hypothesis is predefined. Cytokine studies, QoL and fatigue assessment will be included for hypothesis-generating purposes.
The purpose of this study is to collect DNA samples from patients undergoing routine care at the University of Chicago. These samples will be tested for differences in genes that may suggest greater risk of side effects or chance of increased benefit from certain medications. The results will be made available to the patient's treating physician and the researchers will track whether or not this information is used in routine health care.
The investigators are doing the research to discover genes that cause Inflammatory Bowel Disease (IBD) specifically in the African American population. African Americans with or without Crohn's disease or ulcerative colitis are eligible to join. If you agree to join the study, the investigators will ask for information about your health. The investigators will also ask you to give us a blood sample so that they may discover the genes that cause IBD. The blood sample may be collected at Johns Hopkins or any local facility convenient to you.
The aim of this study is to identify new genes in Chinese patients that help investigators to understand the biological pathway and functions in a population in whom the incidence of Inflammatory Bowel Disease (IBD) is increasing. And to explore the genetic variations in Chinese patients with IBD.
