The goal of this clinical trial is to evaluate the eradication efficacy and health economic benefits of individualized regimens guided by fecal molecular susceptibility testing with 7-day and 14-day courses in the first-line treatment of Helicobacter pylori infection. The main questions it aims to answer are: 1. What is the H. pylori eradication rate of the 7-day versus 14-day individualized regimens? 2. What are the safety, adherence, and cost-effectiveness of the 7-day versus 14-day individualized regimens? Researchers will compare the 7-day course group and the 14-day course group to see if the 7-day course is non-inferior to the 14-day course in terms of eradication rate. Participants will: 1. Undergo fecal H. pylori drug resistance gene testing 2. Receive randomized assignment to either 7-day or 14-day individualized treatment based on drug susceptibility results 3. Complete follow-up visits at 1 week and 4-8 weeks after stopping treatment for adverse event monitoring and 13C-urea breath test

This intervention involves performing polymerase chain reaction (PCR)-based detection of Helicobacter pylori drug resistance genes (including clarithromycin, levofloxacin) from fecal samples. Based on the susceptibility results and penicillin-allergic test, a tailored 7-day triple or quadruple therapy regimen is prescribed, including Tegoprazan , Amoxicillin, Clarithromycin, Levofloxacin, Bismuth Potassium Citrate, Metronidazole, Doxycycline or Minocycline.

Eradication rate of Helicobacter pylori
Eradication of Helicobacter pylori was defined as negative result of urea breath test (\<4‰ cut-off value)
Time frame: 4-8 weeks after treatment
Frequency of adverse events
Any possible adverse events during the treatment period were recorded.
Time frame: Throughout the treatment period, up to 2 weeks
Adherence rate
The proportion of subjects with good adherence. Good adherence was defined as that subjects took more than 80% of the total medication.
Time frame: Throughout the treatment period, up to 2 weeks
