Active clinical trials for "Ulcer"

The purpose of this study is to investigate the safety and efficacy of long-term administration of lansoprazole (Takepron) for up to 12 months in the routine clinical setting in patients receiving low-dose aspirin

Low-dose aspirin is the mainstay of treatment for patients with coronary heart disease and stroke. However, low-dose aspirin increases the risk of ulcer bleeding. Current evidence indicates that 80 - 100 mg of aspirin daily provides good protection against vascular events and the risk of ulcer bleeding is low (about 1% per year). Since the overall risk of bleeding is low, aspirin users who do not have previous ulcer disease do not require prophylaxis with anti-ulcer drugs. In contrast, aspirin users with a history of ulcer disease have a 2- to 4-fold increased risk of ulcer bleeding. The best strategy for reducing the risk of bleeding in high-risk aspirin users remains unclear. Current strategies for high-risk patients include the use of anti-ulcer drugs, elimination of risk factors (e.g. Helicobacter pylori), or the use of enteric-coated aspirin. Although co-therapy of aspirin with an acid suppressant reduces the risk of ulcer bleeding, drug compliance may limit its clinical usefulness particularly in patients who are already receiving multiple drugs. The efficacy of enteric-coated aspirin in preventing ulcer complications showed conflicting results. One study found that enteric-coated aspirin increases the risk of ulcer bleeding. A recent study showed that enteric-coated aspirin causes minimal acute gastric injury. The investigators postulated that among patients without H. pylori infection and a history of ulcer bleeding who continue to use low-dose aspirin, enteric-coated aspirin reduces the long-term risk of ulcer complications to a level that is comparable to that of average-risk aspirin users.

All of us have millions of bacteria living in our gut. These bacteria are very important to our health providing us with protection against infections of the gut, allowing us to gain extra nutritional value from food we eat and helping our immune system. Changes in the balance of these many bacteria can make us vulnerable to infections both from within and from outside the gut. Certain bacteria may also be directly associated with some diseases of the gut. Research by doctors and scientists into relationships between the bacteria normally found in our gut and certain diseases of the gut is helping to develop food supplements and other therapies to treat these diseases. This study involves research into the usefulness and safety of two probiotic products in maintaining remission in Crohn's disease and ulcerative colitis. Approximately 360 patients with Crohn's disease and ulcerative colitis from Ireland, Finland and Spain will be involved in the study. The yoghurts used in this study contain either Lactobacillus salivarius subsp. salivarius or Bifidobacterium infantis.

Follow-Up Study with Retarded Release Phosphatidylcholine in Ulcerative Colitis Objectives: The objective of the study is to evaluate the follow up of patients treated with retarded release phosphatidylcholine in three controlled, randomized studies. Main question is to investigate whether treatment with phosphatidylcholine could spare patients the intake of steroids and immunosuppressants without clinical deterioration. Study population: Retarded release phosphatidylcholine in chronic-active ulcerative colitis. Retarded release phosphatidylcholine in steroid dependent ulcerative colitis. Dose finding study for retarded release phosphatidylcholine Outcome parameters: Definition of remission: SCCAI <2,5 Likert scale: grade 1 or 2 subjective impression of remission: yes/no no blood in stool Definition of relapse: subjective impression: yes/no SCCAI ≥ 5 blood in stool Definition of low clinical activity: SCCAI < 5 Primary endpoint: sparing effect of steroids and/or immunosuppressants by rPC in chronic active UC. Secondary endpoints maintenance of continuous remission improvement of disease activity: a. clinical activity (SCCAI) b.life quality (SIBDQ-D) c.Likert Score relapse rate: a. time to first relapse b. clinical activity during relapses c. number of relapses in relation to length of treatment

Confirmation of safety profile of Pentasa slow release tablets 500 mg in patients with ulcerative colitis (UC).

The objective of this study is to identify the incidence rate; describe the risk factors, clinical presentation, and endoscopic treatment; assess the morbidity, mortality, and overall performance of the management of patients with actively bleeding marginal ulcers after Roux-en-Y gastric bypass (RYGB) surgery.

To explore the hypothesis that leg ulcers are associated with hypercoagulable states, the CLUE study will evaluate patients with connective tissue disease associated leg ulcers, to identify risk factors (especially hypercoagulability and immunologic characteristics), characterize pathogenesis, predict response to therapy, and assess the impact of lower extremity ulcers on quality of life.

Pillcam colon capsule (PCC) endoscopy is a novel strategy tool to inspect colon mucosa. The aim of the present study is to evaluate if PCC endoscopy is able to precisely investigate patients with ulcerative colitis and reach high consistency to conventional colonoscopy.

The purpose of the protocol is to assess the effectiveness of Etiasa® for preventing relapse in Chinese patients with quiescent UC.
