View clinical trials related to Helicobacter Pylori Infection.
Filter by:The researchers recruited gastroenterologists. Physician subjects recruited Helicobacter pylori-positive patients before and after receiving standardized training on Helicobacter pylori eradication. There are no restrictions on treatment options and drugs during the trial. Compare the eradication rate, adverse reaction rate, and patient compliance before and after physician training.
This randomized controlled clinical trial will estimate the eradication efficacy of different therapy for Helicobacter pylori treatment. The completion of this trial will expand new therapy for the treatment of Helicobacter pylori, which can not only ensure clinical efficacy, but also reduce the use of antibiotics.
To perform a prospective, observational, international, multicentre, in vivo study to assess the performance of regular arrangement of collecting venules (RAC) for the exclusion of Helicobacter pylori (Hp) infection using white light high definition (HD) endoscopy without any kind of zoom or magnification. Gold standard will be mucosal biopsies (Sydney protocol) or urease test. Immunohistochemistry (IHC) should be performed in case of a negative histologic study for Hp in patients taking proton pump inhibitors (PPIs). Participants will perform a training test with 20 pictures of the distal part of the lesser curvature before starting the inclusion of cases. Secondary objectives are: - To assess whether age, sex and PPIs, have an influence on the results of RAC. - To assess the correlation of atrophic gastritis and intestinal metaplasia (confirmed in histopathological samples) and RAC. - To assess reproducibility of RAC on real time examinations with different operators and in different countries with different Hp infection prevalence. Primary and secondary variables The primary study variable is: - Endoscopic detection of RAC. Secondary variables will be considered: - Sex - Age - PPI intake in the last two weeks - Centre - Country - Hp prevalence - Endoscopist - Type of endoscope - Significant findings (need of histological confirmation) - Atrophic gastritis - Intestinal metaplasia - Erosive gastritis - Benign gastric ulcer - Gastric adenoma - Gastric cancer
Background: Potent antithrombotic therapy has improved prognosis for patients with acute myocardial infarction (MI) significantly, however, at a price of increased bleeding risk. Helicobacter pylori (H. pylori) infection commonly causes upper gastrointestinal bleeding (UGIB). If systematic screening for H. pylori and subsequent eradication therapy significantly reduces the risk of UGIB and improves outcomes is unknown. Study design: A cluster randomized, cross-over, registry-based clinical trial using nationwide Swedish registries for patient enrollment and data collection. Population: Patients hospitalized for MI at up to 40 hospitals across Sweden. Regional PCI networks comprise 18 clusters. Clusters will be randomized to H. pylori screening or no screening for 1 year after which cross-over to the opposite strategy for 1 year is followed by 1-year follow-up. Intervention: All MI patients will be routinely screened for H. pylori. Patients diagnosed with active H. pylori infection will receive eradication therapy. All follow-up by data collection from national registries. Controls: Standard clinical practice. Data will be collected from national registries. Outcome: Primary outcome is the incidence of hospitalization for UGIB. Secondary outcomes include mortality (all-cause, cardiovascular), cardiovascular endpoints (rehospitalization for MI, heart failure or stroke), or UGIB requiring blood transfusion.
This randomized controlled clinical trial will compare the eradication efficacy of bismuth quadruple therapy containing clarithromycin+metronidazole, clarithromycin+levofloxacin, or metronidazole+levofloxacin for Helicobacter pylori first-line treatment in penicillin-allergic patients. The completion of this trial will expand new therapy for the treatment of Helicobacter pylori, which can not only ensure clinical efficacy, but also reduce the use of antibiotics.
This randomized controlled clinical trial will evaluate the efficacy and safety of proton pump inhibitor, bismuth, metronidazole, and either tetracycline or doxycycline for Helicobacter pylori rescue treatment. The completion of this trial will expand new therapy for the treatment of Helicobacter pylori.
This randomized controlled clinical trial will identify the additional benefit of bismuth or metronidazole in proton pump inhibitor-amoxicillin-containing therapy for Helicobacter pylori first-line treatment. The completion of this trial will expand new therapy for the treatment of Helicobacter pylori, which can not only ensure clinical efficacy, but also reduce the use of antibiotics.
Pepsinogens (PGs) can be used for gastric cancer (GC) screening, but the cutoff levels vary among studies, and PG levels are influenced by numerous factors. To examine the diagnostic value of PG levels and Helicobacter pylori (Hp) status for GC and precancerous lesions screening in asymptomatic individuals undergoing health checkup in China.
The researchers recruited gastroenterologists. Physician subjects recruited Helicobacter pylori-positive patients before and after receiving standardized training on Helicobacter pylori eradication. There are no restrictions on treatment options and drugs during the trial. Compare the eradication rate, adverse reaction rate, and patient compliance before and after physician training.
This study aims to evaluate the efficacy of vonoprazan compared with esomeprazole as first-line treatment for Helicobacter Pylori(Hp) eradication, as well as the safety and economic benefits.
