Important rise in antibiotic resistance rates inHelicobacter pyloriin the Netherlands
Abstract
OBJECTIVE: Description of the changing patterns of antibiotic resistance in Helicobacter pylori infection in the Netherlands.
DESIGN: Retrospective database study using the Dutch infectious disease surveillance information system-antibiotic resistance (ISIS-AR).
METHOD: In the ISIS-AR database antibiotic resistance data are reported by 46 microbiologic laboratories in the Netherlands. For the present study, data from 16 centres were used with a 10 year period of reporting H. pylori resistance data, from 1 January 2010 till 1 January 2020, for amoxycillin, levofloxacin, claritrhromycin, tetracyclin and metronidazole.
RESULTS: In 2019 Antimicrobial resistance rates in the Netherlands were 1% for tetracycline, 5% for amoxycillin, 23%% for levofloxacin, 46% for metronidazole and 47% for clarithromycin. The combined resistance rate for clarithromycin and metronidazole was 29%. Significantly higher resistance rates were found in female patients for amoxycillin (8% vs 1%), clarithromycin (53% vs 38%) and metronidazole (52% vs 38%). From 2010 to 2019, a significant rise in resistance rates was found for amoxycillin (0% - 5%), clarithromycin (7% - 40%), metronidazole (14% - 45%) and for the clarithromycin and metronidazole combination (2% - 29%).
CONCLUSION: There was an important rise in antibiotic resistance rates in H. pylori in the Netherlands. For optimal H. pylori treatment bismuth-based therapies should become available again in the Netherlands. Treatment of H. pylori should…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
