Active clinical trials for "Ulcer"

Evaluation of the non-inferiority of TulleGras M.S.® versus Urgotul® in pain associated with removal of wound dressing during care of venous leg ulcer

The current trial examines the potential benefits of continuous 12 week treatment with Santyl, measured in terms of wound bed appearance. The visual appearance of granulation tissue will be recorded at each visit for the purpose of examining the relationship between wound bed appearance and progress towards healing. In support of this longer treatment regimen with Santyl, a recent animal study found that application of Santyl for 12 weeks was safe and well tolerated. Therefore, the present study is designed to test the hypothesis that daily treatment of diabetic foot ulcers (DFU) with Santyl for up to 12 weeks will result in more rapid development of granulation tissue than DFU treated with supportive care.

Patients with ulcerative colitis (UC) have an increased risk for colorectal cancer (CRC) compared to the general population. Regular screening by colonoscopy is an internationally recommended cancer prevention strategy. Random sampling of the mucosa throughout the colon has been the mainstay of conventional surveillance practice to detect abnormalities, known as dysplasia which can progress to CRC. This requires multiple biopsies, to be taken and processed, a practice which is is tedious, expensive, time consuming and has a low pickup rate. Dysplasia in UC is typically flat and patchy and can be easily overlooked with standard conventional white light colonoscopy (WLC). Detection can be improved by the application of dyes which highlight more subtle abnormalities. This practice, known as chromoendoscopy (CE) is better than WLC at dysplasia detection but more time consuming for the patient and cannot guarantee that the whole colon is covered. CE has only been compared in clinical trials with standard definition endoscopy rather than the recently available high definition endoscopes with better resolution and picture. High definition (HD) endoscopy uses a high definition onitor and a high resolution CCD (charge coupled device) providing much better images than standard video endoscopy. HD colonoscopy promises therefore to provide an alternative to CE in UC surveillance without the need for the extra time and experience required for dye spraying for both endoscopists and nursing staff. The investigators plan to do a randomized trial to assess HD colonoscopy alone compared to chromoendoscopy (with HD colonoscopies) for dysplasia detection during surveillance for ulcerative colitis. There have been no trials comparing these two modalities and the investigators hope to provide evidence that the additional benefit of CE over HD colonoscopy would be marginal and therefore CE would be reserved for procedures using standard definition scopes.

HEAT (Helicobacter Eradication Aspirin Trial) is a large simple double-blind placebo controlled outcomes study of Helicobacter pylori (H. pylori) eradication to prevent ulcer bleeding in aspirin users. It will be run by the University of Nottingham, with recruiting centres across the UK. This trial is funded by the National Institute of Health Research Health Technology Assessment (NIHR HTA) Programme. Aspirin use is widespread and increasing in elderly patients. The main hazard is gastrointestinal bleeding, which may be increasing because of increasing aspirin use. This trial is based on evidence that peptic ulcer bleeding in aspirin users occurs predominantly in H. pylori positive people. Patients will be identified by their GPs, then asked to attend an appointment with a Research Nurse to consent to the trial and take a H. pylori breath test. Those with a positive result will be randomised to receive a one week course of either eradication treatment or placebo. No follow-up visits are required, but instead information will be extracted from the patients' electronic medical record using the MiQuest search tool. The trial will continue until 87 adjudicated events (hospitalisation because of definite or probable peptic ulcer bleeding) have occurred, which would occur after a mean 2.5 patient years of follow-up, if trial assumptions are correct.

Challenges in the treatment of Helicobacter pylori (H. pylori) include increasing antimicrobial resistance and patient's low tolerance to some regimens. Lactobacillus johnsonii (L. johnsonii) and Immunoglobulin Y (IgY) have been shown to decrease the amount and activity of H. pylori in human stomach and can increase patient's tolerance. We conduct a single-center double-masked randomized controlled trial to evaluate the effectiveness of GastimunHp Plus (a product combining L. johnsonii and IgY) in improving the clearance of H. pylori after six to eight weeks of treatment and side effects of H. pylori treatment. H. pylori is tested by C13- or C14-urea breath test.

This will be a phase I/IIa, open-label, three-stage, single center study aimed at investigating the safety, the efficacy (clinical and endoscopic effects) and the pharmacokinetics of Niclosamide enema 150 mg/60 ml and 450 mg/60 ml in subjects with mild-to-moderate UP and UPS, defined as a Modified Mayo Score (MMS) ≥ 4 and < 8, with a stool frequency subscore (SFS) ≥ 1, a rectal bleeding sub-score (RBS) = 1 or 2, and an endoscopic subscore (mucosal appearance) = 1 or 2. At the endoscopic sub-score any degree of friability will be classified as having a sub-scale score of 2.

Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) characterized by chronic inflammation limited to colonic mucosa. Its pathogenesis is not still clear, even if a multifactorial aetiology has been advocated. The aim of this study is to evaluate the long-term efficacy of two different doses of VSL#3® added on standard therapy (5-ASA) in maintaining remission in an adult population of patients with UC, compared with the standard therapy (5-ASA) plus placebo. The investigators hypothesized that adding VSL#3® to mesalamine would lead to higher remission rate at long-term evaluation.

UC is a chronic inflammatory bowel disorder with relapsing and remitting course. The efficacy of mesalazine in preventing relapse in patients with UC is well-known and supported by randomized studies. However, mesalazine can be associated with side-effects. In addition, drug compliance is suboptimal, especially when disease is not active. Curcumin is a natural phytochemical derived from the Indian spice turmeric. It is widely used, has potent anti-inflammatory, anti-oxidant and anti-tumour properties. The aims of this double-blind, placebo-controlled randomized trial is to assess the efficacy of curcumin in the prevention of relapse in patients with ulcerative colitis (UC).

AutoloGel™ Post-Market Surveillance Program Purpose:Evaluate the incidence of hematologic and immunologic adverse events, including coagulopathies in patients with wounds to which AutoloGel™ was applied. Design:Prospective, open label, patient registry. Investigator Sites: 3 Enrollment Size: 300 Subject Population: Patients with exuding wounds, such as leg ulcers, pressure ulcers, and diabetic ulcers and for the management of mechanically or surgically-debrided wounds. Primary Objective Safety: Assess the incidence of hematologic (coagulopathies), immunologic (including anaphylaxis) and other adverse events associated with the application of AutoloGel on exuding wounds, such as leg ulcers, pressure ulcers and diabetic ulcers and during the management of mechanically or surgically-debrided wounds. Primary Safety Endpoint: Absence of coagulopathies caused by inhibitors to coagulation Factor V as determined by a significant prolongation of the prothrombin (PT) time and confirmed by severe depletion of Factor V activity with a positive Bethesda Assay for anti-Factor V functional inhibitors.

The metabolic response to ulcerative colitis, including increased proteolysis and lipolysis and changes in energy expenditure, plays a significant role in the resulting malnutrition from which these patients suffer. Tumor necrosis factor-alpha (TNF-alpha), a pro-inflammatory cytokine, has been found to be elevated in children with ulcerative colitis. TNF-alpha has been incriminated in the mechanism of weight loss in many different chronic diseases, and causes net protein and lipid catabolism. Anti-TNF-alpha antibody (infliximab) has been proven to be an effective therapy for ulcerative colitis. The purpose of this study is to determine changes in protein and lipid metabolism, as well as resting energy expenditure, before and after therapy with anti-TNF-alpha antibody (infliximab) in children with ulcerative colitis. Performing this study will better define the changes in nutrition status observed in these children following remission of active ulcerative colitis, and potentially lead to changes in medical and nutritional management of these children
