Filter by:The aim of colonoscopy is to visualize the inside of the entire large bowel. Several factors can make the procedure difficult, and sometimes a complete examination is not possible. Complicating factors include poor bowel preparation and technical challenges such as differences in anatomy (long, redundant colonic segments), post-surgical adhesions, strictures and diverticulosis. A special endoscope with two inflatable balloons, originally designed to examine the small bowel, has been used for several years with success in such technically difficult colonoscopies. More recently a modified double-balloon instrument was designed specifically for colonoscopy, but the documentation of the performance of this instrument is limited. The aim of the present study is to investigate the performance of the double-balloon colonoscope in cases where conventional colonoscopy have failed due to technical difficulties.
Anemia is the the most frequently extradigestive symptom for Inflammatory Bowel Disease. This is due to iron deficiency and inflammation. Most of treatments aim to control inflammation using anti-TNF alpha therapy which should theorically reduce anemia. The aim of the study is to show that perfusion of iron associated to anti-TNF therapy should reduce anemia and improve quality of life of patients.
The aim of this study is to compare the gut microbiota in Chinese patients with Inflammatory Bowel Disease (IBD) in Hong Kong with that of healthy controls, compare the gut microbiota in IBD patients in a developing country (low but increasing IBD incidence, Hong Kong) with those in a developed country (high incidence, Australia), compare the gut microbiota in Chinese patients with IBD in Hong Kong with the microbiota of their non-IBD affected parents and siblings.
This study will assess the safety and tolerability of AIN457 in patients with moderate to severe Crohn's disease who already participated and completed the core trial CAIN457A2202.
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.
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.
The purpose of this study is to evaluate if the combination of oral budesonide and rectal hydrocortisone improves symptoms in patients with active ulcerative colitis. Also, we would like to determine if oral budesonide and rectal hydrocortisone has fewer and less severe side effects compared to standard steroids (prednisone).
Inflammatory bowel disease (IBD) is a common chronic inflammatory disorder, but a noninvasive method of assessing disease location, severity, and extent is currently not available. Recently published animal data suggests that using transabdominal ultrasound enhanced with encapsulated gaseous microbubbles may provide a reliable, noninvasive means to detect and quantify areas of intestinal inflammation. This study will evaluate the role of Contrast-enhanced ultrasonography (CEU) for use as a diagnostic tool in patients with IBD. We hypothesize that the severity and extent of chronic intestinal inflammation, as quantified by CEU-derived video intensity scores, will correlate with endoscopically-derived measures of intestinal inflammation as obtained from the Crohn's Disease Endoscopic Inflammatory Index (CDEIS). A total of 40 patients will be enrolled in the study, 30 patients with IBD and 10 patients undergoing colonoscopy for other reasons. Prior to colonoscopy CEU assessment of small and large intestine will be performed to evaluate neoangiogenesis and intestinal blood flow. The correlation between the CEU-derived video intensity score and CDEIS will be assessed using Pearson's correlation coefficient. Subjects may also undergo scoring using the Rutgeerts Score, an endoscopic disease assessment index used to score disease activity in patients with previous ileocolonic resection. Comparing video intensity between IBD and non-IBD subjects will be performed using the Wilcoxon rank sum test, with a secondary aim of establishing preliminary estimates of the sensitivity of the microbubble scoring system.
Registration of patients referred for colon investigation by barium enema, CT colonography and colonoscopy in two hospitals and one radiology centre in Telemark, Norway, for a period of minimum six months. Indications, delay and results of procedure will be recorded.Hypothesis: Choice of procedure for colon investigation is not based solely on clinical indication, but factors like delay, patient preference, lack of knowledge about the the procedures by the referring physician may have a decisive influence. The study will also analyse the correlation between patients symptoms, clinical findings and laboratory results and major pathology findings by colon investigation. Further, delay from patient´s first symptoms to finally diagnosis by colon investigation will also be registered and analysed.
Colectomy with creation of an ileal pouch (IPAA) is now the treatment of choice for patients with ulcerative colitis that is resistant to existing medical therapies. The development of inflammation in these ileal reservoirs, a clinical entity referred to as pouchitis, is the most common long-term complication of this procedure and can affect 50-60% of adults and children. We have previously demonstrated that clotrimazole (delivered as a rectal suppository) is generally safe, effective, and displays poor systemic absorption when used in pediatric and adults with active pouchitis. We saw clinical benefit in patients with pouch disease that had previously failed to respond to standard antibiotic, steroid, or immunosuppressive therapies. The clinical trial outlined here will define the effectiveness and safety of topical clotrimazole therapy (delivered as a rectal enema) in pediatric (aged greater than two years) and adult patients with pouchitis. Subjects in this study will be randomly assigned to receive either placebo (no active drug, 4 subjects) or one of two clotrimazole therapy groups: 2500 mg/day (8 subjects) or 4000mg/day (8 subjects). No washout period is required, and subjects will be allowed to continue their existing anti-inflammatory medications during their participation in the study. Clotrimazole will be delivered nightly in the form of an enema. Subjects will undergo flexible sigmoidoscopy (pouchoscopy) prior to and again after completing one month of study therapy, and pouch disease activity will be graded at after each procedure using the Pouchitis Disease Activity Index (PDAI). Clinical improvement will be defined as a drop in PDAI score. If the drop in PDAI scores between placebo and either active clotrimazole treatment group is not significant, and no subject experiences what are determined to be study-related adverse effects, a second cohort of subjects will be recruited and studied after receiving one month of either placebo (4 subjects), 6000 mg/day clotrimazole (8 subjects), or 7500mg/day clotrimazole (8 subjects). Subjects will be assessed for adverse effects at the midpoint of the study. Clotrimazole blood levels will be measured during the first and last day of study participation. In addition, adults will complete a health related quality of life assessment at baseline and after completing study drug therapy. All subjects will be eligible for one month of open-label study drug therapy after completing one month of study drug therapy.
