Filter by:This is a longitudinal observational study on patients with gastrointestinal and related disease. The study will be conducted for at least 10 years, following each participant over time, as they either go through relapses and remissions, or progression of their disease.
OBJECTIVES: Up to 15% of patients with peptic ulcer bleeding will develop rebleeding, mainly in those with ulcers of higher-risk stigmata (i.e. Forrest class Ia to IIb). Randomized trials show that second-look endoscopy is effective in reducing rebleeding rate. However, whether to withhold aspirin or other anti-platelet agents (for the treatment of established cardiovascular or cerebrovascular diseases) remains controversial. Studies have shown that although continuation of anti-platelet agents reduces mortality rate due to reduced cardiovascular and cerebrovascular events, there is a marginal increase in rebleeding risk. HYPOTHESIS: We hypothesize that continuation of aspirin or other anti-platelet agents coupled with second-look endoscopy could reduce the rebleeding rate without increasing the risk of thromboembolic events in high-risk patients.
Although stress ulcer is a complication that can cause significant mortality and morbidity in critical patients with risk factors, there is still lack of consensus about its prophylaxis. There are also few data available from Taiwan. H2 blockers are commonly used due to convenience. Some prefer sucralfate (a mucosal protective agent) for the sake of less association with nosocomial pneumonia. Recently, proton pump inhibitors were shown to have good prophylactic effects for stress ulcer. Pantoprazole (iv) is the first intravenous form of proton pump inhibitor that was approved by FDA. There are some reports about its application for treatment of peptic ulcer bleeding. It also has good acid suppression effect in patients under critical care. We expect that intravenous pantoprazole will have a role in stress ulcer prophylaxis. We will enroll those patients that have received major abdominal surgery and admitted to surgical ICU. After obtaining the consent, we will give them prophylactic drugs for 7 days within 24 hours. They are randomly allocated to 2 groups. Group I: pantoprazole 40 mg iv bolus stat and then qd ; Group II: famotidine 20 mg iv bolus stat and then q12h. We will monitor the following data: operation type & time, APACHE II score, CBC, CXR, stool character and OB test, NG aspirate. If clinical evidence of UGI bleeding occurs, endoscopic examination will be performed. We define the end point as overt bleeding, death or transfer out of ICU. We will compare the prevalence of UGI bleeding and ventilator associated pneumonia in these 2 groups
The purpose of this study is to determine whether lansoprazole, once daily (QD), compared to gefarnate, twice daily (BID), is effective in preventing the recurrence of gastric and duodenal ulcers in patients receiving long term treatment with low dosage aspirin.
This randomized, double-blind, parallel-group, controlled, multi-center clinical trial of 6 months duration is designed to assess the efficacy, tolerability and safety of PN400 versus diclofenac/misoprostol in subjects at high risk for developing NSAID-associated gastric ulcers. Approximately 100 sites will participate to enroll a total of 200 subjects (100 per arm). At least 20% of the subjects enrolled will be age 65 years and older.
The purpose of this study is to evaluate the safety of rabeprazole 20mg/day in polymedicated patients and to examine the necessity of adjusted dosage in both therapies (rabeprazole and concomitant drug). Proton pump inhibitors (PPI) act in the final step of the gastric secretion. PPI's block ATP-ase H+/K+ in gastric parietals cells. It has been described that inhibition of acid secretion has produced the recovery of the gastroesophageal pathology in a high percentage of the patients resistant to conventional drugs. In this context, the objective of the study is to evaluate the safety of rabeprazole as a concomitant treatment and examine the clinical practice the interaction with drugs whose absorption has gastric pH dependence.
Two groups of patients were randomised into two groups of either transnasal gastroscopy or conventional type gastroscopy (n=98). The aim of the study was to evaluate the cardiorespiratory effects and sideeffects of the two methods, and to evaluate the technical features of the transnasal endoscope.
