Active clinical trials for "Peptic Ulcer"

The combined diagnostic accuracy of MCCE and UBT in Hong Kong patients with uninvestigated dyspepsia between age 35 to 60 years for structural pathology and HP infection is comparable to that of conventional UGI endoscopy with histological examination for HP

A bleeding peptic ulcer remains a serious medical problem with significant morbidity and mortality. Endoscopic therapy significantly reduces further bleeding, surgery, and mortality in patients with bleeding peptic ulcers and is now recommended as the first hemostatic modality for these patients. In the past few years, adjuvant use of a high-dose proton pump inhibitor (PPI) after endoscopic therapy has been endorsed in some studies. Laine and Javid et al found that oral PPI and IV PPI had a similar intragastric pH response in the past two years. Therefore, whether oral can replace IV in the management of peptic ulcer bleeding is the objective in this study. The investigators enrolled 130 patients with active bleeding or nonbleeding visible vessels（NBVV） in this study. They are randomly assigned as oral lansoprazole or IV nexium group. All patients receive successful endoscopic therapy with heater probe or hemoclip placement. In the lansoprazole group (N=65), 30 mg four times daily is given orally for three days. Thereafter, the patients receive 30 mg lansoprazole orally daily for two months. In the nexium group, 160 mg/day continuous infusion is given for three days. Thereafter, the patients receive 40 mg nexium orally daily for two months. The primary end point is recurrent bleeding before discharge and within 14 days. At day 14, volume of blood transfused, number of surgeries performed, and the mortality rates of the two groups are compared as well.

A large dose of PPI is effective in preventing peptic ulcer rebleeding. The investigators hypothesize that 40 mg/q6h pantoloc is equivalent to 8mg/h pantoloc in preventing rebleeding.

The purpose of this study is to evaluate whether HZT-501 is effective in reducing the rate of development of ibuprofen-associated ulcers in patients who require long-term daily use of ibuprofen.

The aim of this study is to compare the efficacy of a proton pump inhibitor (lansoprazole) and a histamine-2 receptor antagonist (famotidine) in preventing recurrent ulcer bleeding in patients with a history of H. pylori-negative idiopathic peptic ulcers.

Low-dose aspirin can prevent cerebral and cardiovascular accidents in individuals with symptomatic atherothrombotic disease, but its use is frequently limited by gastrointestinal side effects. The position of H2-receptor antagonists as a step-down therapy after healing of peptic ulcer or erosions by proton pump inhibitor is unclear. The objective of this randomized, double blinded control study was to compare the efficacy of high-dose famotidine with pantoprazole in the prevention of recurrent dyspeptic or complicated ulcer/ erosions in patients taking low-dose aspirin

This study was designed to investigate the safety and immunogenicity of Chiron's investigational H. pylori (HP3) vaccine

The purpose of this study is to evaluate the efficacy and safety of intravenous pantoprazole in the prevention of rebleeding in patients with bleeding peptic ulcer disease after successful endoscopic hemostatic therapy.

The purpose of this study is to evaluate the efficacy and safety by comparing prevention of recurrent peptic ulcer in low-dose aspirin users between PMK-S005 and Placebo.

Aim of prospective randomized a placebo controlled study is to prove that in case of acute surgical procedure due to appendicitis, ileus of small bowel and perforation of small bowel and stomach appropriately administered antibiotic prophylaxis is effective with lower incidence of infection in surgical site and comparable risk of development of other nosocomial infections versus group without antibiotic prophylaxis. Secondary aim is to determine risk of developing nosocomial infection in the above mentioned group of patients, identify group of patients which does not benefit from prophylaxis, and compile financial costs for antibiotic prophylaxis and treatment of nosocomial infections and thus the background for the recommended procedure with regards that such prospective study does not exist in the Czech Republic.
