Filter by:Objectives: A recent randomized trial showed that 14-day sequential therapy containing high dose proton pump inhibitor was higher than 95% in the first line treatment. However, whether the 14-day sequential therapy is more effective than 10-day bismuth quadruple therapy remains unknown. Therefore, the investigators aimed to compare the eradication rates and long term re-infection rates of sequential therapy for 14 days versus bismuth quadruple therapy for 10 days in the second line treatment.
The "test and treat" strategy for treating dyspeptic patients who are H. pylori positive is rapidly becoming the standard of care. This study will test the effectiveness of RHB-105, a new triple therapy to treat H. pylori infection in dyspeptic patients against an active comparator.
It was suggested that the patient compliance plans an important role in the Hp eradication. However, data on whether re-education could improve the eradication rate are lacking. We consider that re-education on patients by telephone during the process of drug administration could increase the eradication rate in Hp infected patients. We hypothesized that telephone re-education during the whole process of drug administration would improve the compliance of patients and ultimately increase the Hp eradication rate.
The aim of the study is to evaluate the effects of the synbiotic Bifidobacterium animalis ssp. lactis B94 plus inulin addition to the standard triple therapy on Helicobacter pylori infection eradication rates in children.
Helicobacter pylori is a Gram-negative bacterium with a helical bacillus shape that it's able to penetrate and colonize the stomach mucosal lining by infecting it. The eradication treatment of H. pylori is supported by numerous consensus groups worldwide and it is generally safe and well tolerated. Standard treatment is based on multiple drug regimens. However, its effectiveness has been increasingly compromised due to the emergence of resistant strains, as well as poor adherence to treatment. Therefore, it's proposed a randomized, double-blind, placebo-controlled study whose aims are: 1. Determine whether the combination of two probiotic strains of L reuteri (Gastrus) will improve gastrointestinal symptoms when associated with four-way therapy (of any type). 2. Prove whether supplementation with Gastrus (food supplement) versus Placebo is able to reduce the gastrointestinal adverse effects of quadruple eradication therapy. They will be determined by the GSRS gastrointestinal symptom scale in routine clinical practice.
This study is an etiologic trial to test the hypothesis that predicts that Helicobacter pylori eradication in asymptomatic/mildly dyspeptic adults will result in an increase in body iron. The study will assign and aims to complete the follow-up of 240 subjects half of them assigned to a highly effective FDA approved 14-day course of a 3-1 capsule containing bismuth subcitrate, metronidazole and tetracycline plus omeprazole which is now OTC. We have tested the effectiveness of this therapy in the study population and it seems to yield almost 100% eradication on PP analysis. We need the best possible, near 100% eradication rate, which we have already obtained in a pilot, to make comparisons on ITT basis and safely conclude that H pylori leads to a deficit of body iron.
Helicobacter pylori is a bacterium estimated to colonize in the gastrointestinal tract of the half population in the world. Colonization of this bacteria is suspected to be one of the main risk factor for the occurrence of various abnormalities of the upper gastrointestinal tract, such as peptic ulcer and gastrointestinal cancer. The Experts recommend giving triple therapy regimens as first-line eradication therapy for Helicobacter pylori infection. The recommended duration of triple therapy is 10-14 days. However, recent studies suggest triple therapy with longer duration will provide a higher percentage of eradication. This study wanted to show whether 14 days of triple therapy was better than 10 days in Helicobacter pylori eradication.
The purpose of this study was to evaluate the efficacy and compliance of tailored therapy which using the polymerase chain reaction for point mutation of clarithromycin, compared to concomitant therapy, in patients without history of H. pylori eradication.
Helicobacter pylori (H. pylori) is the most common chronic bacterial infection in humans. The prevalence of H. pylori is about 30~50% in the Western adult population. It is estimated that about 50% of people are infected with this bacterium in Taiwan. Many studies have shown that H. pylori is an important causal factor of chronic gastritis, peptic ulcer disease, gastric cancer and gastric lymphoma. The World Health Organization classified H. pylori as a Group 1 carcinogen in 1994. Endoscopic examination is indicated to confirm the above diagnosis for patient with H. pylori infection. Eradication of H. pylori infection reduces the risk of gastric cancer and recurrence of peptic ulcer disease. However, the eradication rate of clarithromycin-based triple therapy has been declining in recent years, probably related to the increasing resistant rate to clarithromycin. Several strategies have been proposed to overcome the declining eradication rate, including (1) extending the treatment duration of triple therapy to 14 days; (2) the use of bismuth quadruple therapy which contains bismuth, a proton pump inhibitor, and two antibiotics (usually metronidazole and tetracycline); (3) non-bismuth quadruple therapy (concomitant therapy) which contains a proton pump inhibitor and three antibiotics (usually amoxicillin, metronidazole, and clarithromycin); (4) sequential therapy which contains a proton pump inhibitor (PPI) plus amoxicillin for five days, followed by a PPI plus clarithromycin and tinidazole for another five days. The investigators aim to improve the eradication rate of H. pylori infection while an endoscopic examination is performed.
This randomized controlled study aimed to evaluate whether adding bismuth to the standard first-line triple therapy could improve the eradication rate of Helicobacter pylori (H. pylori). A total of 162 patients with H. pylori infection were randomly assigned to either the 7-day triple therapy group (n = 81) or the bismuth plus triple therapy group (n = 81). The triple therapy (RAK) contained the twice-daily dosage of rabeprazole 20mg, amoxicillin 1g and clarithromycin 500mg. In the RBAK group, bismuth subcitrate 360 mg twice daily was added to the RAK regimen.
