Active clinical trials for "Colitis, Ulcerative"

The purpose of this study is to investigate the accuracy of second generation colon capsule (C2) in evaluating colonic mucosal inflammation of ulcerative colitis patients, using conventional endoscopy as the gold standard.

Patients with inflammatory bowel disease (IBD) will be assessed for immunologic response to pneumococcal vaccination. Patients with IBD meet criteria as outlined by the Centers for Disease Control (CDC) for pneumococcal vaccination, yet the investigators have found that pneumococcal vaccination in this population is under-utilized. It is unknown whether or not IBD or IBD-related medications impact the immune response to this recommended vaccine. Three groups of 25 patients each will be recruited. The first group will consist of outpatients with IBD who are receiving infliximab (Remicade TM) while on concommitant immunosuppressive therapy (with either 6MP, azathioprine, or methotrexate). This group is intended to represent a common 'heavily immunosuppressed' patient group with IBD. The second group will consist of patients with IBD seen in our outpatient clinic who are not on any immune-suppressive medications. These patients meet CDC criteria for vaccination by virtue of having a chronic medical illness. The third group will consist of healthy age-matched (to the first group) controls. After obtaining informed consent, patients will be screened with baseline lab tests including testing for antibodies against pneumococcus. At the baseline visit, patients will also undergo a brief medical history, physical examination, and assessment of their IBD disease activity. Included patients will then undergo a one-time intramuscular vaccination with 23-valent polysaccharide pneumococcal vaccine (Pneumovax TM). One month later, subjects will return for a blood draw to assess for response to pneumococcal vaccination.

Study Hypothesis UC Disease affects the colon. PillCam IBD may be used for visualization of the colon mucosa in UC Disease patients. This study is designed to evaluate the yield and clinical impact of IBD capsule in detecting lesions associated with UC Disease and to determine the agreement between PillCam Platform with the IBD capsule and optical colonoscopy in the evaluation of UC disease extent. Primary Scientific Objective To evaluate the agreement between PillCam IBD system and optical colonoscopy in the evaluation of UC disease extent (Non-active disease, Proctitis, Left-sided colitis, Pancolitis) Proposed Design Established UC disease patients whose clinical condition suggests ongoing disease activity, aged 18 years and up, who have no evidence of symptomatic stricture or other obstruction that would prevent capsule passage will be enrolled in this study. Patients will undergo bowel prep, followed by a PillCam IBD capsule examination and colonoscopy examination. The Rapid videos will be evaluated by two readers, each from a different site, the colonoscopy videos will be evaluated by two other physicians, at the sites INCLUSION CRITERIA All subjects must fulfill all of the following inclusion criteria: Patients ages 18 years and up Patient has known UC according to physician discretion Patient has at least one positive inflammatory marker from the following: ESR CRP CBC Patient is indicated and eligible for a standard of care colonoscopy examination Patient agrees to sign consent form EXCLUSION CRITERIA The presence of any of the following will exclude a patient from study enrollment: Crohn's Disease Antibiotic Associated Colitis Stool positive for O&P (C&S within 3 months of enrollment) Other known infectious cause of increased symptoms Known intestinal obstruction or current obstructive symptoms, such as severe abdominal pain with accompanying nausea or vomiting. Definite long stricture seen on radiological exam. Non-steroidal anti-inflammatory drugs including Aspirin, (twice weekly or more) during the 4 weeks preceding enrollment Suspected GI stricture, followed by patency capsule study or other imaging study that could not prove patency of the GI tract. Patient has had prior abdominal surgery of the gastrointestinal tract in the last 6 months, other than uncomplicated procedures that would be unlikely to lead to bowel obstruction based on the clinical judgment of the investigator. Patient is expected to undergo MRI examination within 7 days after ingestion of the capsule. Patient with known gastrointestinal motility disorders. Subjects with known or suspected delayed gastric emptying Patient suffers from any condition, such as swallowing problems, which precludes compliance with study and/or device instructions. Patient has Type 1 or Type II Diabetes. Patient has any allergy or other known contraindication to the medications used in the study. Patient has any condition, which precludes compliance with study and/or device instructions. Women who are either pregnant or nursing at the time of screening, or are of child-bearing potential and do not practice medically acceptable methods of contraception. Concurrent participation in another clinical trial using any investigational drug or device. Patient suffers from a life threatening condition Patients with history or clinical evidence of renal disease and/or previous clinically significant laboratory abnormalities of renal function parameters.

The primary aim is to evaluate if introduction of eHealth in its form of the web application Constant-Care (https://ibd.constant-care.com) could reduce the length of hospitalization in patients with acute severe Ulcerative Colitis treated with infliximab. This is relative to historical controls extracted from medical records. Patients will self-measure on the web-application while hospitalized as well as after discharge. At the web-application different questionnaires are filled out and a fecal calprotectin (FC) analysis is performed on a smartphone. The final follow up is one year after admission.

This is a multi-centre, randomised, controlled, investigator blinded study. The randomisation will be done centrally. The patients will be treated for 1 year, with clinical and laboratory assessments at 0, 4, 8 and 12 months. Endoscopic examination is at enrollment and on completion of the study (at relapse or after 12 months). Number of Subjects (Planned and Analysed): 360 patients for demonstration of non-inferiority between once daily and twice daily; 326 to be analysed in per-protocol (PP) analyses; and 360 in intention-to-treat (ITT) analyses.

Ulcerative colitis is a systemic disease we assume that extra intestinal involvement as we describein our study( Fireman Z, Osipov A, Kivity S, Kopelman Y, Sternberg A Fireman E: Assessment of pulmonary involvement in Crohn's disease by induced sputum. Am J Gastroenterol 2000;95(30):730-734. )

Colonoscopy is considered crucial for the diagnosis and quantification of ulcerative colitis (UC). However, there are several drawbacks related to the invasiveness, procedure-related discomfort, risk of bowel perforation (especially in the period of acute inflammation), and relatively poor patient acceptance. Most patients regard the necessary bowel cleansing as burdensome. Feasible, accurate and well accepted non-invasive diagnostic techniques are needed for the determination of inflammatory activity and optimal tailoring of therapy. Hybrid PET/MRI represents an innovative combination of two established, non-invasive diagnostic tools: Magnetic resonance imaging (MRI), allowing for anatomic-functional imaging of the abdomen at high soft tissue contrast and positron emission tomography (PET) utilizing 18F-fluorodeoxyglucose (FDG) a non-invasive tool to monitor glucose metabolism and allowing a detection and quantification of inflammatory processes. Since MRI has limited sensitivity in UC and may be hampered by retained stool, a combination with another imaging modality is very appealing. PET, on the other side provides functional information, yet with limited anatomical landmarks and is relatively unsusceptible to artifacts associated to retained stool. In combination, these modalities might provide a valid alternative for the non-invasive assessment of the inflammatory activity in UC patients without the need for bowel purgation. It will therefore have to be investigated whether fecal material does impede the diagnostic quality of the combination of FDG-PET and MRI. For this purpose, the investigators will include 50 patients with confirmed ulcerative colitis. Dependent on clinical activity of the inflammation, patients will be randomized to undergo PET/MRI enterography either with or without prior bowel purgation followed by a colonoscopy. Inflammatory activity in 7 bowel segments will be analyzed based on PET/MRI with and without bowel purgation with the results of colonoscopy as standard of reference. Patient acceptance of PET/MRI with and without bowel purgation as well as colonoscopy will be compared. PET/MRI with and without bowel cleansing will be compared with regard to diagnostic accuracy as well as for its patients' acceptance in comparison to colonoscopy. The investigators hypothesize that PET/MRI will eventually be highly accurate to detect and monitor inflammatory activity in patients with ulcerative colitis. Additional information about extra-intestinal findings might also change the therapeutic concept. PET/MRI might serve as a non-invasive diagnostic option in patients with UC to quantify inflammatory activity especially when bowel cleansing or colonoscopy is not applicable.

The objective of this RCT is to compare the postoperative outcome of transanal versus transabdominal minimally invasive proctectomy with ileal pouch-annal anastomosis in patients with ulcerative colitis.

Monocentric, prospective interventional study to assess the degree of disease activity with a multispectral optoacoustic tomography (MSOT) handheld scanner in patients with Crohn's disease or ulcerative colitis.

The primary endpoint of the study will be to compare the accuracy of two procedures (FICE with target biopsies only, versus conventional white light colonoscopy with recommended targeted and random biopsies) in the endoscopic surveillance of patient with long-standing UC. Accuracy will be measured based on the number of patients with confirmed neoplasia using each technique. The combined histological outcome following the two procedures will represent the gold-standard diagnosis for each patient. Secondary outcomes will be the number of patients with false-positive findings, the number of neoplastic lesions detected, the number of false-positive lesions per patient for each technique and the total time required for each procedure.
