Pattern of drug resistant Helicobacter pylori in dyspeptic patients in Thailand.
Article Dans Anglais | IMSEAR | ID: sea-41225
ABSTRACT
Emergence of drug resistant Helicobacter pylori (H. pylori) has occurred in various countries and could compromise the efficacy of current treatment regimens. The aim of the study was to identify the pattern of antibiotic resistant H. pylori in Thailand and evaluate various factors associated with drug resistance. Between June 2001 and December 2002, a total of 560 dyspeptic patients who underwent upper gastrointestinal endoscopy at King Chulalongkorn Memorial Hospital were included in this study. Antral gastric biopsies were obtained for H. pylori cultures and susceptibility tests using Epsilometer test (E-test). The value of antibiotic resistant breakpoints were amoxicillin 0.5 microg/ml, clarithromycin 1.0 microg/ml, metronidazole 8 microg/ml, and tetracycline 4 microg/ml, respectively. H. pylori were detected in 315 patients using the rapid urease test (56.25%). Cultures for H. pylori were positive in 172 patients. E-test for all four antibiotics was successfully placed in 79 isolations. The prevalence of antibiotic resistant H. pylori were amoxicillin 13.9 per cent (11/79), clarithromycin 19.0 per cent (15/79), metronidazole 30.4 per cent (24/79), tetracycline 5.1 per cent (4/79), and multi-drugs 16.5 per cent (13/79), respectively. However, age, sex, or endoscopic findings did not differ between the patients with H. pylori resistant strains and sensitive strains. The emergence of antibiotic and multi-drug resistant H. pylori in Thailand were relatively high and these could compromise the efficacy of current treatment regimens. The factors associated with drug resistant H. pylori could not be demonstrated in the present study. Further study in a larger number of patients might be necessary to identify factors associated with resistant H. pylori.
