Abstract
[Objective] We intended to evaluate endoscopically a cure rate for Helicobacter pylori infection by dual rabeprazole/amoxicillin therapy in relation to CYP2C19 genotype status prospectively. [Methods] Sixty-five patients with gastritis and H.pylori infection completed the dual therapy with 20 mg of omeprazole bid, 1000 mg of amoxicillin bid and clarithromycin 500 mg bid for 1 week. Then omeprazole was medicated at the dose of 20 mg bid to inhibit gastric acid secretion. CYP2C19 genotype status was determined by a PCR-restriction fragment length polymorphism method. The symptomatic and endoscopic evaluation was performed at the baseline and 4-week post-treatment periods. [Results] Of the 65 patients, 24 were homozygous extensive metabolizers (homEM), 31 were heterozygous extensive metabolizers (hetEM), and 10 were poor metabolizers (PM). Significant differences in healingrates of duodenal ulcer among the homEM, hetEM and PM groups were observed: 75.0%, 90.3%, and 100%, respectively (P<0.05). Cure rate in H.pylori infection PM patients was significantly (P<0.05) greater than in homEM and hetEM patients, respectively. [Conclusions] The cure rates for duodenal ulcer and H.pylori infection by dual omeprazole/amoxicillin therapy depend on the CYP2C19 genotype status. The genotyping test of CYP2C19 appears a clinically useful tool for the optimal dual treatment with omeprazole plus amoxicillin.关键词
