研究目的:

通过前瞻性、单中心、观察性队列研究,评估伏诺拉生联合四环素二联(VT二联)治疗幽门螺杆菌后胃肠道菌群在短期和长期的变化特征,探索其在微生态层面的影响及潜在优势,为临床治疗方案的优化提供科学依据。  

Objectives of Study:

Through a prospective, single-center, observational cohort study, we aim to evaluate both the short-term and long-term changes in the gastrointestinal microbiota following Vonoprazan-Tetracycline (VT) dual therapy for Helicobacter pylori eradication. The objective is to explore the ecological impact and potential advantages of this regimen, thereby providing a scientific foundation for optimizing clinical treatment strategies.

Exclusion criteria:

1. Long-term use of medications that may affect the gastrointestinal microecology, such as oral probiotics. 2. Previous Helicobacter pylori eradication therapy that included tetracycline. 3. Pregnant or breastfeeding women. 4. Use of medications within 4 weeks prior to treatment that may influence the results, such as bismuth agents, acid suppressants (PPI or P-CAB), or antibiotics. 5. History of gastrointestinal surgery. 6. Presence of other serious diseases that could interfere with the evaluation of this study, such as severe liver disease, pulmonary disease, hematological disorders, endocrine disorders, cardiovascular disease, renal disease, malignant tumors, or alcohol abuse. 7. Concurrent medical conditions that may affect the gastrointestinal microecology. 8. Participation in another drug study within 3 months prior to the use of the study drug. 9. Inability to accurately express subjective symptoms, such as in patients with psychosis or severe psychoneurosis, rendering them unable to cooperate with the study. 10. Other conditions deemed by the investigator as inappropriate for participation in this study.

指标中文名:

治疗前及治疗后不同时间的粪便16S rRNA测序以及宏基因组测序变化情况

指标类型:

Outcome:

Changes in fecal 16S rRNA sequencing and metagenomic sequencing before treatment and at various time points after treatment

Type:

Primary indicator

测量时间点:

治疗前(0周)、用药后2周、用药后8周及用药后6个月共四个时间点

测量方法:

收集患者粪便标本,采用 16S rRNA 基因测序及宏基因组测序技术分析肠道菌群的组成及结构变化,同时开展粪便细菌耐药基因的检测。通过比较不同时间点肠道菌群特征的变化,评估 VT 二联治疗对幽门螺杆菌感染患者胃肠道微生态的短期及中期影响。

Measure time point of outcome:

At four time points: before treatment (week 0), 2 weeks,8 weeks and 6 months after treatment

Measure method:

Fecal specimens were collected from patients, and 16S rRNA gene sequencing along with metagenomic sequencing technologies were employed to analyze the compositional and structural changes in the intestinal microbiota. Concurrently, the detection of antimicrobial resistance genes in fecal bacteria was conducted. By comparing the characteristics of the gut microbiota at different time points, the short- to medium-term impact of VT dual therapy on the gastrointestinal microecology of patients with
