Helicobacter pylori (H. pylori) is closely related to the occurrence of gastric cancer and other diseases, the discovery and eradication of H. pylori infection has great significance to the prevention and treatment of related diseases. At the same time,understanding the influencing factors of H. pylori infection and eradication failure in the population can provide a scientific basis for the formulation of local H. pylori prevention and control strategies. So, the investigators intend to analyze the factors related to H. pylori infection and eradication failure in the outpatients of gastroenterology clinics in Xi'an, China.
Taking 300 permanent residents in Xi'an area who will go to the Gastroenterology Clinic of the Second Affiliated Hospital of Xi'an Jiaotong University from February 2022 to March 2023 and undergo 13C-UBT examination as the research object. A questionnaire survey on factors related to H. pylori infection and eradication failure will be conducted. The questionnaire includes basic Information, eating patterns, living environment, related gastrointestinal symptoms, etc. Among the outpatients, H. pylori-positive patients will be given rabeprazole 10 mg + amoxicillin 1000 mg + clarithromycin 500 mg + colloidal bismuth tartrate 220 mg bid for 14 days. After 4-6 weeks of completing eradication therapy, 13C-UBT will be performed to determine whether H. pylori is eradicated. According to the results of 13C-UBT at the beginning and results of 13C-UBT after eradication treatment, outpatients will be divided into three groups: H. pylori negative group, H. pylori positive radical cure successful group and H. pylori positive radical cure failed group. Next using SPSS 19.0 Statistical software analyzes H. pylori infection and eradication failure related influencing factors.
