Active clinical trials for "Inflammatory Bowel Diseases"

This is a study for people with inflammatory bowel disease ("IBD"--that is, ulcerative colitis, Crohn's colitis, or indeterminate colitis). We are studying how people with IBD decide to have surgery when a doctor has told them they should think about having their colon (large bowel) removed. This surgery is called a "colectomy." Patients will be asked to fill out a questionnaire that takes about 60 to 90 minutes to complete. Questions ask about patients' background (age, etc.) and their IBD. They also ask about patients' decision to have surgery or not to have surgery. For instance, what kinds of things did they think about? Some questions ask about other people who affected the choice and how patients felt about the help they got from others. People who wish to join the study will receive payment to thank them for their time. Patients must be at least 18 years old Patients must speak English Patients must have been told by their doctor to think about having surgery to take out their colon to (a) lower their risk for cancer or (b) because they have pre-cancer (called "dysplasia") Patients do not need to have had the surgery--they may have already had the surgery, they may not have had it yet, or they may have decided they do not want to have it

This study will evaluate and compare the genes of the telomere repair complex in healthy control subjects, patients with blood diseases, and patients with inflammatory bowel disease to identify what, if any, changes are associated specifically with inflammatory bowel disease. Patients between 2 and 80 years of age with ulcerative colitis or regional enteritis may be eligible for this study. Participants are recruited from the practice of Dr. Stuart Danovitch, Washington, D.C. Researchers have established that minor differences in a specific set of genes called the telomere repair complex are related to immune-mediated diseases of the bone marrow. NIH researchers are now interested in whether inflammatory bowel disease and other autoimmune diseases show a similar pattern of genetic differences. Participants provide a cell sample for evaluation of the telomere repair complex. The sample is collected via buccal swab, a gentle scraping of the inside of the cheek, and stored for use in research.

An increase prevalence of CMV, EBV and or HHV-6 in diseased tissue of inflammatory bowel disease would suggest a role for these viruses in the etiology and/or exacerbation of IBD, whereas their absence would preclude such association.

The investigators hypothesize that PSC in children is associated with mutations and functional changes of the cystic fibrosis (CF) gene.

The purpose of this study is to evaluate the percentage of moderate to severe IBD participants with active disease at Day 1.

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 positive test (positive predictive value (PPV)) and the predictive value of a negative test (Negative Predictive Value (NPV)) using the proposed test outcomes for BÜHLMANN Calprotectin Test results when used in patients referred for diagnostic evaluation with signs and symptoms suggestive of either IBS or IBD. To confirm the inter-laboratory consistency of test results for the BÜHLMANN fCAL™ ELISA. To provide exploratory observations of test results in patients between the age of 2 and 21 years. To provide a sample set from normal subjects with no symptoms or signs of gastrointestinal disease for use in Expected Value Testing.

Background: The immunologic response to stress is regulated by the cytokines. Anti-Tumor Necrosis Factor-α agents are antibodies directed against a key cytokine in the process angiogenesis and collagen synthesis. It is not known whether they intervene with surgical stress response increasing the rate of postoperative complications. Method: Un-blinded prospective, non-interventional cohort single centre study including all the patients with Crohn's disease and Ulcerative Colitis undergoing abdominal surgery. Immunological and endocrinological parameters will measured in blood samples taken from these patients before and after surgery. Power calculations showed that 17 patients in each arm are needed.

The purpose of this study is to characterize the treatment patterns associated with biologics agents use or non-biological therapy in participants with moderate to severe Ulcerative Colitis (UC) and Crohn's Disease (CD).

Inflammatory bowel disease (IBD), consisting of two major forms, Crohn's disease (CD) and ulcerative colitis (UC), affects more than 1.6 million people in the United States alone. Though the precise mechanisms underlying the inflammation and immune responses in IBD are still being investigated, various inflammatory mediators, including pro-inflammatory cytokines, and genes have been implicated in the disease process. At present, there are no reliable mechanisms to predict response to individual IBD medications. The investigators seek to evaluate whether inflammatory cytokines change longitudinally during treatment with anti-cytokine agents in both treatment primary responders and primary non-responders. In addition, the investigators will be evaluating the pharmacogenetics of treatment response to these agents.

Vascular complications in patients with inflammatory bowel disease (IBD), comprising mainly Crohn's disease (CD) and ulcerative colitis (UC), representing 2% extra-intestinal complications. In over 60% of cases, these vascular complications of deep venous thrombosis (DVT) or pulmonary embolism (PE). Several studies have shown that patients with IBD have a risk of venous thromboembolic disease (VTE) increased from 1.5 to 3.5. This risk is closely related to disease activity.
