Antimicrobial resistance of Helicobacter pylori in West Flanders - Belgium: an observational cross-sectional study
Abstract
OBJECTIVES: Data on Helicobacter pylori (HP) resistance in Belgium are largely based on the patient population of Brussels and Wallonia. Notably Brussels harbours a large proportion of patients with a migration background which might not be representative for other parts of the country.
METHODS: An observational cross-sectional study was performed in the province of West Flanders, Belgium for collecting gastric biopsies to examine the resistance of HP. The study population consisted of patients who underwent a gastroduodenoscopy for any medically indicated purpose. Rapid urease testing (RUT) was performed on all biopsies and cultures were only started if the RUT showed positive.
RESULTS: 512 patients participated of whom 495 were eligible for analysis: 438 in first line testing and 57 in second line. The growth of HP was successful in 88.9% (n = 88/99) of which 52.3% (n = 46/88) resulted in an antibiogram. The resistance rate in first line was based on 37 succeeded antibiograms and showed 13.5% resistance for clarithromycin (95% confidence interval; 2.5% to 24.5%); 29.7% for metronidazole; 29.7% for levofloxacin; 11.4% for rifampicin; 2.7% for amoxicillin and 0% for tetracycline.
CONCLUSION: The primary clarithromycin resistance rate of HP could still be slightly under 15% in West Flanders, Belgium. This might implicate a clarithromycin-based triple therapy is an option for first line empiric eradication in this region according to the Maastricht V/Florence consensus…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 512 participants or records.
