简要总结

This study was conducted to investigate the effects of high-dose diphtherapy and bismuth quadruple therapy on H. pylori eradication on intestinal microecology, to clarify the changes in intestinal microbiota diversity and structure before and after the two treatment regimens, and to explore the relationship between different treatment regimens and intestinal microbiota dysbiosis; to further guide the safety and drug resistance of H. pylori eradication by the two treatment regimens. The expected results are to observe the changes of intestinal microbiota diversity and structure before and after treatment with the two treatment regimens.

详细描述

The trial can be divided into three phases.

  1. Enrollment screening phase: patients who had been clearly diagnosed with Hp infection and had not received antibiotic therapy and met the inclusion and exclusion criteria were informed and signed informed consent forms, their basic data information was collected, medical history and laboratory tests before enrollment were taken; if they met the requirements of the trial protocol they were included in the study, and patients' stools were collected for 16S rRNA gene sequencing.
  2. Treatment period: Patients were enrolled according to a randomized number table provided in advance by a third party, and patients were randomized in a 1:1 ratio to high-dose diphtherapy and bismuth quadruple therapy to receive 2 weeks of Hp eradication treatment. During the treatment period, patients were provided with written instructions on how to take the medication, instructed on the correct way to take the medication, and improved their compliance; patients were asked to record their symptoms and adverse reactions during the medication period, and were informed of the visiting telephone number and visiting WeChat, so that they could keep in touch with the investigator at any time.
  3. Follow-up period: At the end of treatment (i.e., day 14 from the start of treatment), patients were asked to return at that time to have their stools sequenced for 16S rRNA gene, and 6 weeks after the end of treatment (i.e., day 56 from the start of treatment), patients were asked to return at that time to undergo rapid urease test (RUT), 13C/14C-urea breath test (13C/14C-UBT), or fecal Hp antigen test. ) or fecal Hp antigen assay (HpSA), with the results recorded on a CRF form, and the patient's stool collected for 16S rRNA gene sequencing.

结局指标

主要结局

Changes in the diversity and structure of fecal microbiota

时间窗: before treatment,1day after treatment,6 weeks after treatment

Feces from subjects before treatment , after eradication treatment , and at week 6 after eradication treatment were analyzed for gut microbiota diversity by 16S rRNA gene sequencing, including alpha diversity (representing the abundance of species in the microbial ecosystem, i.e., the number of different species, and evenness, i.e., similar abundance or dominance of some species over others) and beta diversity (representing the difference in microbial composition in one environment compared to another).We will explore the changes in intestinal microbiota diversity and structure before and after treatment with both treatment regimens.

次要结局

  • Eradication rate of Helicobacter pylori(28 days after treatment)
