Filter by:Our previous study included 119 Helicobacter pylori(H. pylori)-infected Chinese patients without previous eradication history who were randomized to low-or high-dose amoxicillin-vonoprazan regimens consisting of amoxicillin 1 gram either b.i.d. or t.i.d plus vonoprazan 20 mg b.i.d for 7 or 10 days. Neither 7-or 10-day VA dual therapy with either b.i.d. or t.i.d. amoxicillin achieved satisfied efficacy (i.e., <90%) when given as first-line treatment for H. pylori infection. This study evaluated the efficacy and safety of low-and high-dose amoxicillin-vonoprazan dual therapy for 14 days as first-line treatment for H. pylori in China.
Estimating the prevalence of Helicobacter Pylori infection in newly diagnosed stomach cancers in the West-Indies will help to understand the epidemiology of this cancer, which is over-incident in the West Indies compared to France. In addition, the constitution of a biobank (tumor tissues, healthy tissues and serum) will allow to set up in a second time etiological studies to identify other risk factors in particular in connection with the exposure to environmental pollutants to adapt the prevention measures.
The aim of this study is to compare the usual rapid urease test (RUT) to a new florescent-labeled urease inhibitor marker to diagnose Helicobacter Pylori.
The purpose of this study is to assess and compare the effectiveness and safety of high-dose dual therapy and half-dose clarithromycin-containing bismuth quadruple therapy in elderly patients for eradicating H.pylori.
Strongly evidence supports that H. pylori eradication is an effective approach to reduce the incidence of those pathologies. However, due to the increasing resistance rates to antibiotics, failures of H. pylori eradication get more and more common. Thus, rescue therapy for persistent H. pylori infection is becoming a grand challenge the investigators have to face.
Helicobacter pylori (H. pylori) infection, affecting an estimated 50% of the global population, is a main cause of chronic gastritis, peptic ulcers and gastric cancer. By causing progressive damage to the stomach and may eventually result in gastric atrophy, H. pylori infection has been demonstrated to be responsible for more than 95% of gastric malignancies
STUDY PROTOCOL: The study will include 30 patients ages 18-80y that had a gastroscopy for various reasons. The patients should not be on PPI therapy . If during the gastroscopy there are some pathologies that require a second look endoscopy after some weeks of therapy (ulcers or esophagitis), the investigators will repeat the gastroscopy within a month. During the first gastroscopy a biopsy will be taken for histological examination and for a rapid urease test and an urea breath test will be done soon after the procedure. If one of the tests is positive the investigators postulate that the Helicobacter pylori is actually present. After the gastroscopy the patient is given a full dose of PPI (as indicated) and helicobacter tests are repeated in the next endoscopy (under PPI therapy) . Any positive test that become negative in the second endoscopy is considered false negative.
