Active clinical trials for "Colitis"

This study adopts a multicenter, randomized, double-blind, low-medium-high dose group and placebo parallel controlled clinical study design. After screening, patients with active ulcerative colitis who meet the inclusion criteria and do not meet the exclusion criteria will be randomized by 1:1:1:1 to Hemay007 400 mg BID group, 800 mg QD group, 600 mg BID group or placebo group, with proposed 72 cases in each group. After 12 weeks of double-blind inductive treatment period, the patients will enter the Hemay007 open treatment period of 12 weeks when Hemay007 600 mg BID will be used as the medication regimen. All randomized subjects who have received the investigational drug should be subjected to a 4-week observation after the end of treatment.

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.

Colitis is inflammation of the large bowel and it is often caused by conditions known as ulcerative colitis and Crohn's disease. In these conditions, the body has an exaggerated inflammatory response against the bowel - the body attacks the bowel. Patients who have had colitis affecting most of the large bowel for more than 8 years are at increased risk of cancer of the large bowel. In view of this, many national gastroenterology organisations have recommended that such patients have regular colonoscopies to detect pre-cancerous areas and even early cancer in the large bowel. Early detection of such areas, will lead to early treatment thereby reducing the risk of developing significant large bowel cancer. These regular colonoscopies are known as surveillance colonoscopies. Official international guidelines for surveillance in patients with ulcerative and Crohn's colitis advise to take 4 random samples of large bowel tissue (biopsies) every 10 centimeters and of any suspicious areas. Recent studies have shown that spraying dye such as indigo carmine (a type of food dye) helps highlight abnormal areas that could harbor pre-cancerous cells. This technique is time-consuming, and tedious. There are no set standards of what is considered a satisfactorily completed dye spray colonoscopy. The uptake of this technique in the UK has not been uniform. Therefore virtual chromoendoscopy has been studied as an alternative method to improve the detection of pre-cancerous tissue in patients with longstanding colitis.

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.

study is to determine if proton pump inhibitors plus enteral nutrition is superior to enteral nutrition alone as a stress ulcer prophylaxis strategy in critically ill patients in terms of incidence of overt and significant GI bleeding related to stress gastropathy.

The investigators examined the outcome of patients with severe Enterohaemorrhagic E. Coli (EHEC) O104:H4 infection suffering from bloody diarrhoea that were at risk to develop hemolytic uremic syndrome and underwent repetitive whole bowl lavage during hospitalization.

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. )
