Filter by:The aim of this study is to assess the effect of oral Helicobacter pylori infection on the efficacy of gastric Helicobacter pylori infection eradication. Patients diagnosed with gastric Helicobacter pylori infection are tested for oral Helicobacter pylori and given standard bismuth quadruple therapy, with a urea breath test, a rapid urease test, or a Helicobacter pylori stool antigen test to confirm gastric Helicobacter pylori eradication at week 6 follow-up, and an oral Helicobacter pylori test kit to confirm oral Helicobacter pylori eradication.
Helicobacter pylori (H. pylori) infection remains a major public health problem, with an estimated prevalence of over 50% worldwide and 60-86% for Portugal. H. pylori is associated with significant morbidity and mortality from peptic ulcerative disease to gastric cancer, whose eradication therapy has proven to be effective in preventing these complications. Factors involved in the development of these conditions include H. pylori virulence, host genetic factors and gut microbiota. Given the increasing pattern of antibiotic resistance evidenced by this bacterium and the scarcity of available antibiotic therapy, both in Portugal and worldwide, there is not enough evidence on the best eradication strategy. Regarding the uncertainties about the potential negative impact of indiscriminate use of eradication therapy on gut microbiota, either by proton pump inhibitors or by antibiotics per se, there is an overriding need for evidence about the real impact of this therapy on oral or gut flora and possible clinical consequences in immunological, metabolic, nutritional and oncological terms. Objectives: Comparative evaluation of the efficacy of the different quadruple therapy regimens recommended for the H. pylori eradication. Comparative evaluation of the safety profile in terms of clinical, and immunological and gut microbiota impact of the different therapies for the H. pylori eradication.
To evaluate the efficacy and safety of dual or triple regimes for Helicobacter Pylori eradication using Vonoprazan as the antiacid agent.
This is a multi-center, non-randomized, open label study. Subjects will be enrolled on a walk-in basis. Screening data will be reviewed to determine subject eligibility. Subjects who meet all inclusion criteria and none of the exclusion criteria will be entered into the study. All children will be exposed to non-radioactive 13C-Urea with citric acid, and shall submit a stool sample. Centers will house a PyloPlus UBT Analyzer to document results. PyloPlus Analyzer results shall remain blinded to the investigator and treating physician. No patient management decisions should be made based on the investigational PyloPlus® UBT System. Treating physician will prescribe a H. Pylori Stool Antigen Test to Stool test at either LabCorp or Quest Diagnostic, for the patient, which will be used for diagnostic purposes by the ordering physician. Total duration of study is anticipated to be approximately 6 months.
The study will evaluate the eradication rate and tolerability of modified LOAD regimens (three antibiotics and a proton pump inhibitor (lansoprazole)) for management of HP infection in treatment-naive patients as well as patients who failed previous therapies.
Since much is unknown about factors that lead to progression of the pre-neoplastic lesions and cancer. In addition, there is ongoing debate on the optimal surveillance intervals and techniques. To solve these important clinical questions, the establishment of a registry for a longitudinal study is planned.
The habit of family meals makes the infection rate of Helicobacter pylori high in China, which is also the main cause of reinfection of Helicobacter pylori. Eating together can easily cause family members to be infected with Helicobacter pylori. We used a real-world study to understand the risk factors, epidemiological characteristics, and safety and effectiveness of eradication therapy for helicobacter pylori infection in family-based screening and treatment.
Use the two-categorical variable , eradicate success or failure ,as a dependent variable, and analyze the influential factors by logistic regression.And then the statistically significant influencing factors like gastric mucosal pathology are obtained.We build a predictive model of the outcome of Hp eradication therapy based on significant influencing factors. The difference with p 0.05 is statistically significant.
The patients who accept the quadruple eradication program of the helicobacter pylori and success to eradicate helicobacter pylori will be followed-up to observe the situation of re-infection of helicobacter pylori.
The antimicrobial resistance of helicobacter pylori in Shandong province was analyzed by helicobacter pylori antibiotic sensitivity test.And the map of antimicrobial resistance of helicobacter pylori was constructed to provide clinical guidance for selecting effective eradication program and improve the eradication rate.
