Background:
Iatrogenic factors play an important role in H. pylori eradication failure, whereas it can be easily missed. Therefore, we aimed to investigate and analyze these related iatrogenic factors of H. pylori eradication failure.
Methods:
A total of 508 patients who experienced H. pylori eradication failure were included in this study conducted from December 2019 to February 2022. All the patients filled out a questionnaire including demographic characteristics, duration of treatment, regimens, dosage, and time intervals in rescue treatment.
Results:
In the first-line treatment, 89 patients (17.5%, 89/508) used at least one antibiotic with high resistance rate in triple therapy and 57 patients (11.2%, 57/508) used two antibiotics with high resistance rates or other not recommended antibiotics in quadruple therapy. In the rescue therapy, 85 regimens were repeatedly used as salvage regimens in 58 patients (22.6%, 58/257) and 178 regimens containing antibiotics with high resistance rates were repeatedly used in 85 patients (33.1%, 85/257).
Conclusion:
To decrease the risk of H. pylori eradication failure, iatrogenic factors need to gain more attention. Clinicians should enhance their education and training to standardize the treatment regimens, better manage the H. pylori infection, and improve the eradication rate eventually.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
