Active clinical trials for "Peptic Ulcer"

In a prospective randomised study design to investigate, if a systematic risk factor screening for bleeding ulcer in patients, who following percutaneous coronary intervention (PCI) commence a one year combination treatment with low dose aspirin and clopidogrel, followed by prophylactic treatment with a proton pump inhibitor (PPI) in case of increased risk, can reduce the risk of bleeding ulcer. Based on the recently raised suspicion that PPI's, possibly except pantoprazole, reduce the effect of ADP-receptor inhibitors, pantoprazole has been chosen as prophylaxis in the screening group, and analyses will be done to ascertain whether PPI treatment increases the risk of coronary events. Further analyses will be made to see whether PPI prophylaxis in high risk patients can increase compliance with the antithrombotic treatment through a reduction of side effects, thereby reducing the risk of myocardial infarction in particular stent thrombosis. The study population will be analyzed further to identify the patients, who will benefit the most from PPI prophylaxis Hypothesis: screening heart patients for risk factors for bleeding ulcer and subsequently treating high risk patients with PPI can reduce the incidence of bleeding ulcer and increase compliance with the antithrombotic treatment; thereby possibly reducing the risk of coronary events and improving survival. Initial a description of the prevalence of risk factors will be done.

The purpose of this study is to compare the effect of esomeprazole 20 or 40 mg once daily versus placebo on the occurrence of peptic ulcers during 26 weeks in subjects on continuous low-dose acetylsalicylic acid.

This study is being carried out to see if constant 3 days infusion of Nexium is effective in preventing rebleeding after an endoscopic treatment.

The investigators used two different doses of esomeprazole (40 mg IV q.d. and 40 mg IV q6h for three days followed by esomeprazole 40 mg q.d. orally in two groups) after successful endoscopic therapy with heat probe therapy or hemoclip placement. The goal of this study is to assess the outcomes of two different regimens of low vs. high dose of intravenous esomeprazole after endoscopic therapy in patients with peptic ulcer bleeding.

Acute upper gastrointestinal bleeding (UGIB) is one of the commonest medical emergencies. The condition accounts for 150 per 100,000 populations. A National United Kingdom reported a crude overall mortality rate of 10%. While bleeding stops spontaneously in majority of patients at their presentation, there remains a subgroup of patients who continue to bleed or develop recurrent bleeding. In these patients, the mortality increases manifolds. If these high-risk patients can be identified, early interventions may improve their outcomes. Several prognostic indices are in use for the purpose of patient stratification. They include the Rockall, Glasgow-Blatchford (GBS) and the Baylor scores. The Rockall score is a composite score which incorporates clinical parameters as well as findings during endoscopy which was derived to predict mortality. The GBS is a pre-endoscopy or a clinical score for the prediction for the need of further intervention loosely defined as the need for transfusion, endoscopy or surgery. It has been shown to be accurate in identifying low risk patients for early discharge.

The purpose of this study is to determine whether a long-term prophylactic use of esomeprazole 20 mg twice daily or once daily has prevention effectiveness in reducing the recurrence of peptic ulcer bleeding after ulcer healed with 16-week oral esomeprazole therapy in high-risk patients whose Rockall score ≥ 6.

The aim of this study is to compare the clinical effectiveness of intravenous esomeprazole and pantoprazole in preventing recurrent bleeding in the patients with high-risk bleeding peptic ulcers after successful standard endoscopic hemostasis.

Although all PPIs are effective, there are some differences in their clinical performance, particularly in terms of the degree and speed of gastric acid suppression. Few data are also available about their effect of the pathophysiological mechanisms of gastritis and peptic ulcer disease. Aim of the present study is to investigate the effect of therapy with esomeprazole or rabeprazole on the mechanism of pathogenesis of gastritis and particularly on the pattern of release of pro- and anti- inflammatory cytokines associated to peptic ulcerative process by the gastric mucosa.

This is a multicenter, randomized, double-blind, parallel-group, dose-ranging, comparator-controlled study of the effect of pantoprazole on intragastric pH after successful endoscopic hemostasis in hospitalized patients. Patients will receive either intravenous pantoprazole (one of two regimens) or ranitidine (the comparator) within 2 hours of successful hemostasis and administration will continue for 72 hours after hemostasis.

Whether H2 receptor antagonist can prevent thienopyridine-related peptic ulcer remains unclear.
