This study aims to assess Efficacy of vonoprazan based dual and triple therapy for naïve patient with Helicopacter Pylori infection in Sohag Government .
NCT03597672
To establish prospective cohort of healthy population and corresponding serum sample bank in Sichuan province to provide platform for exploring early diagnosis and screening strategy of gastric cancer by a prospective cohort study.
NCT01505127
The purpose of this study is to confirm the efficacy of triple therapy with TAK-438, Amoxicillin and Clarithromycin, twice daily (BID) by demonstrating its non-inferiority to triple therapy with Lansoprazole, Amoxicillin and Clarithromycin in H. pylori-positive patients with scarred gastric or duodenal ulcers.
NCT00885417
Helicobacter pylori infection has been shown to be associated with the development of gastric cancer and peptic ulcer diseases. Eradication of H. pylori infection could reduce the occurence or recurrence of these diseases. However, it was estimated that 15-20% of patients would fail from first line standard eradication therapy and need second line rescue therapy. About 15-30% of patient would fail from second line therapy and need to be rescued with third line therapy. The commonly used salvage regimens include: 1. Bismuth based quadruple therapy (combined with ranitidine or proton-pump inhibitor (PPI) plus two antibiotics) 2. Levofloxacin or moxifloxacin or rifabutin based triple therapy. However, Bismuth is not available in many countries and the administration method is complex. Its usage is limited by the high pill number and low compliance rate. In recent years, the concept of sequential therapy has been advocated in the treatment of H. pylori infection. The regimen includes a PPI plus amoxicillin for five days, followed by a PPI plus clarithromycin and metronidazole for another five days. The eradication rate in the first line treatment of sequential therapy had been reported to be as high as 90%. More importantly, it has been demonstrated that the eradication rate among patients with clarithromycin-resistant strains could be as high as 89%. Aims: Therefore, the investigators aim to assess the efficacy of levofloxacin-based sequential therapy as second line therapy for those who fail from one standard eradication therapy.
NCT00155623
The aims of this prospective study are: (1) to prospectively investigate the "true" prevalence rate, the acquisition and spontaneous clearance of H. pylori infection year by year in the population whose ages between seven and fifteen. (2) to explore the risk factors of transmission of H. pylori infection in Taiwan.
