Abstract
Background: Resistance of Helicobacter pylori (H. pylori) to antibiotics is increasing worldwide. The study was aimed to understand the current situation of antibiotic resistance in Nanjing and to provide a reasonable basis for clinical selection of antibiotics to cure H. pylori.
Objective: To investigate the current status of H. pylori antibiotics resistance in the Nanjing area, and analyze the primary and post-treatment antibiotic resistance of H. pylori in this area.
Methods: During the period from July 2017 to December 2019, 1533 gastric mucosal specimens from patients with positive H. pylori confirmed by a breath test or rapid urease test were collected for isolation and identification of H. pylori. The agar dilution method was used for the antibiotic resistance test.
Results: The result showed that the resistance rates of H. pylori to amoxicillin, clarithromycin, levofloxacin, furazolidone, tetracycline and metronidazole were 2.74%, 47.03%, 33.59%, 0.91%, 0.52% and 80.76%, respectively in the period of July 2017 to December 2019. The resistance rates of H. pylori (primary vs. post-treatment) to amoxicillin, clarithromycin, levofloxacin, furazolidone, tetracycline and metronidazole were 1.83% vs. 6.08%, 38.62% vs. 77.81%, 27.41% vs. 56.23%, 0.58% vs. 2.13%, 0.33% vs. 1.22%, 78.57% vs. 88.75%, respectively.
Conclusion: Antibiotic resistance of H. pylori remained a problem for the effective eradication of this pathogen and its associated diseases in the Nanjing area. For post-treatment eradication patients, clinicians should take into account regional antibiotic resistance rate, personal antibiotic exposure history, economic benefit ratio, adverse antibiotic reactions, antibiotic availability and other aspects.
Keywords: Helicobacter pylori, the primary and post-treatment antibiotic resistance, Nanjing area, antibiotic availability, adverse antibiotic reactions, antibiotic exposure history.
