Filter by:The purpose of this study is to evaluate whether a medical device/implant (InterStimTM) will help patients to have more normal bowel movements. The InterStimTM device is a neuromodulating device. Neuromodulation is a way of changing the activity of the nervous system by using electrical stimulation. InterStimTM is FDA approved to help people who have a hard time controlling their bowl movements. This is called fecal incontinence.The device is placed near a nerve root in the lower back. It works in a manner similar to a pacemaker by releasing electrical stimulation that triggers the S3 nerve root. When being placed, it is initially tested to make sure it will work using a temporary wire and then, if successful, the device is permanently implanted.
This study aims to determine the prevalence of HBV infection in patients with IBD and rheumatologic disease, and to assess the impact of immunosuppressive therapy on viral load and clinical course of IBD patients.
The investigators hypothesised that a video based patient education will help patients understand the process of colon cleansing prior to a colonoscopy procedure and hence will result in clean colons that will may help physician perform a better quality examination.
The small bowel is poorly suited to standard endoscopy techniques due to its anatomical differences from the colon and the upper gastrointestinal tract. The small bowel has an average length of 6.7 m, with a free mesentery that resists standard "push to advance" endoscopy techniques. New developments in overtubes, which are placed over an enteroscope, have revolutionized doctors ability to deeply intubate the small bowel. Three types of 'augmented' enteroscopy, double balloon enteroscopy (DBE), single balloon enteroscopy (SBE) and spiral enteroscopy (SE), have been developed. Although studies have been performed on these individual techniques, there are no studies comparing SBE and SE, the two techniques used in Johns Hopkins. The investigators propose performing a prospective, randomised trial, to assess the differences between these two techniques. The question of what differences there are between these two techniques, in terms of depth of insertion, diagnostic and therapeutic yields, time required for the procedure and the sedation requirements, are important questions to answer, and depending on the results, would affect the investigators approach to patients with small bowel disease.
Background: - Bone marrow stromal cells (BMSCs) are cells that can develop into other tissue types, including bone, cartilage, marrow, and blood cells. However, BMSCs are not stem cells there is no evidence that after infusion into another person that BMSCs change into any other cells. Research suggests that BMSCs can travel to different parts of the body and work with immune cells to reduce inflammation and help repair damaged tissues. BMSC infusions have been used in tests to treat moderate to severe inflammatory bowel disease, like Crohn's disease (CD) or ulcerative colitis (UC). These tests have shown some good results, but more research is needed to study their safety and effectiveness. Researchers want to see how well BMSC infusions work to treat CD and UC. The BMSCs will be collected from volunteer donors. Objectives: - To look at the safety and effectiveness of BMSC infusions for moderate to severe CD and UC. Eligibility: - Individuals between 18 and 65 years old with moderate or severe inflammatory bowel disease (CD or UC) that has not responded to standard treatment. Design: - Participants will have two screening visits. The first will be 15 to 30 days before the first BMSC infusion. The second will be within 14 days of the first BMSC infusion. - At the first screening visit, participants will have a physical exam and medical history. They will provide blood, urine, and stool samples. They will also give information about their symptoms and quality of life. - At the second screening visit, participants will have their vital signs (like blood pressure and heart rate) measured. They will also provide blood samples, and have a colonoscopy with biopsies. - During treatment, participants will have one BMSC infusion per week for 4 weeks. Blood and urine samples will be collected at each treatment visit. - One week after the last infusion, participants will have a study visit. The tests from the first and second screening visits will be repeated. - There will be six follow-up visits at 1, 2, 3, 6, 12, and 24 months after the last study visit. Participants will repeat the tests from the first screening visit.
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.
Protein Losing Enteropathy (PLE) is a serious medical condition that may develop in children and adults with congenital heart disease for which a palliative procedure known as the "Fontan procedure" has been performed. The loss of serum proteins into the gastrointestinal tract that is associated with PLE can cause serious symptoms and life-threatening complications. A number of clinical studies have suggested that heparin administration can have clinical benefit in children with PLE, however the risk of bleeding associated with the administration of heparin is an important concern and commonly limits its administration. ODSH is a desulfated heparin with minimal anticoagulation properties but which, in pre-clinical studies, appears to have the potential to replace heparin and greatly reduce the risk of bleeding. This open label study is to assess the safety and evidence of therapeutic effect of the administration of ODSH as a 4-day continuous intravenous infusion in patients with an exacerbation of their PLE.
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.
The principle objective of this study is to validate confocal endomicroscopy (CEM) in a national, multicenter study, in terms of its ability to diagnose neoplastic lesions in vivo, in two groups of patients at high risk of colorectal cancer (CRC): patients with familial adenomatous polyposis (FAP) after colectomy in whom the neoplastic lesions are probably under-diagnosed, and patients with inflammatory bowel diseases (IBD) in whom endoscopic surveillance is particularly difficult. Methods: The study will be comprised of two phases (Phase I and II). Phase I will serve to validate at the multicenter level the results of the first, recently published, monocenter German study in terms of capacity of CEM to identify the colonic neoplastic lesions in vivo. Phase II is destined to prospectively evaluate the diagnostic yield of CEM in detection and prediction of neoplastic lesions by developing and adding new features to the confocal pattern of in vivo diagnosis. Two cohorts of patients will be studied in parallel: Patients with inflammatory bowel diseases (IBD), like ulcerative colitis (UC) or Crohn's disease (CD), including those before planned colectomy, and patients with FAP after colectomy. During lower endoscopy performed under general anaesthesia, each colonic segment will be examined before and after staining with indigo-carmin. After intra-venous fluorescein injection, all macroscopically abnormal lesions will be examined by CEM, then biopsied. In parallel, multiple random biopsies will be performed, each coupled with simultaneous CEM "optical biopsy" at the same point. In addition, during Phase II, in IBD patients before planned colectomy and in patients with FAP, a "mapping" of colonic mucosa, by obtaining a very high number of CEM "optical biopsies", will be performed, and will be correlated with standard histology performed either on colectomy specimens (IBD) or on standard biopsies (FAP). Principal analysis (Phase I and II) will include evaluation of inter-observer variation in terms of interpretation of in vivo histology and diagnostic yield of CEM with respect to the detection of neoplastic lesions by evaluation of sensitivity and specificity, using standard histology as reference method. Additional analysis (Phase II) will be performed to evaluate the diagnostic and predictive (CRC risk) value of "colonic mapping" by correlating optical images pattern score to results of standard histology. Expected results: This study should guarantee high quality data, standardization of procedures and of interpretation of CEM images, which are prerequisite for dissemination of CEM in clinical practice. The investigators expect to show that CME allows to reliably discriminate between neoplastic and non-neoplastic lesions, that, compared to standard histology, provides better characterization of lesions, especially in the context of extended lesions like in IBD, an finally, that CME images can be used to develop a new "optical biopsy"-based score allowing prediction of high CRC risk in patients with FAP and IBD. The investigators believe that CEM may increase, as compared to currently used techniques, the diagnostic yield in terms of probability of the detection of neoplastic lesions in patients at high risk of CCR, and may become a new standard for endoscopic surveillance in these patients.
