Helicobacter Pylori Infection

Brief summary

This study aims to evaluate the efficacy and safety of 14-day quadruple therapy based on fecal molecular antimicrobial susceptibility tests for the first-line eradication of H. pylori infection, thus, providing more evidence to inform the value of fecal antimicrobial susceptibility tests in the first-line treatment of H. pylori infection.

Detailed description

The eradication rate of H. pylori is decreasing year by year due to the occurrence of bacterial resistance, especially clarithromycin, one of the most widely-used antimicrobials against H. pylori. Understanding antibiotic resistance before treatment may be the main determinant of the successful eradication of H. pylori. Nevertheless, due to the invasive examination of sampling, the economy-benefit ratio, and the harsh cultivation conditions, traditional antimicrobial susceptibility test is rarely used before first-line eradication treatment in the real world. As an alternative, faster and simpler molecular methods applied to fecal samples obviate the need for endoscopy and provide the possibility to popularize the antimicrobial susceptibility tests catering to initial treatment. This study aims to explore the efficacy, safety, and economic benefits of the first-line therapy for H. pylori guided by fecal antimicrobial susceptibility tests.

Inclusion criteria

Participants enrolled should meet the following criteria: (1) Participants aged 18-65 with no history of eradication treatment; (2) diagnosed as H. pylori infection by one or more of the following methodologies: gastric biopsy using histochemical staining, tissue culture, the 14C-urea breath test (UBT), the 13C-UBT, and/or fecal antigen; (3) were requested to undergo an endoscopy before the eradication treatment if they have alarm symptoms, a family history of gastric cancer or age over 40 years old without undergoing an endoscopy before; and (4) voluntarily participated in the clinical trial and have signed the informed consent.

Design outcomes

Primary

MeasureTime frameDescription
Helicobacter pylori Eradication RateSix to eight weeks after completion of the medicationHelicobacter pylori Eradication will be determined by 13C-urea breath test or 14C-urea breath test six to eight weeks after completion of the medication.

Secondary

MeasureTime frameDescription
Rate of Adverse Drug Reaction(ADR)Within 7 days after completion of therapyAdverse drug reactions are classified into six types (with mnemonics): dose-related (Augmented), non-dose-related (Bizarre), dose-related and time-related (Chronic), time-related (Delayed), withdrawal (End of use), and failure of therapy (Failure).
Compliance RateWithin 7 days after completion of therapyCompliance was defined as poor when they had taken less than 80% of the total medication.
