Extensive Metabolizers Were Different.

At 1 unit of time, H. pylori was eradicated in 29% of extensive metabolizers, 60% of intermediate metabolizers, and 100% of poor metabolizers (extensive metabolizers vs intermediate metabolizers, p=0.028; extensive metabolizers vs poor metabolizers, p<0.001; intermediate metabolizers vs poor metabolizers, p=0.034).
The authors concluded that eradication rates were dependent on the polymorphic spoken language of CYP2C19.
They also proposed that one antibiotic (amoxicillin) in improver to omeprazole may be sufficient in poor metabolizers.
Another learning by the same investigative building block followed 97 Altaic language subjects (50% men, mean age 55.1 ± 10.9 yrs) with gastritis and H. pylori pathologic process, who received dual therapy with rabeprazole 20 mg/day and amoxicillin 1500 mg/day for 2 weeks. Of the 97 patients, 33 were extensive metabolizers, 48 were intermediate metabolizers, and 16 were poor metabolizers.
Statistically significant differences in eradication rates were demonstrated among the different genotypes: 61% (95% CI 42-77%) in extensive metabolizers, 92% (95% CI 80-98%) in intermediate metabolizers, and 93% (95% CI 70-100%) in poor metabolizers (p=0.0007).
Specifically, extensive metabolizers were different from poor metabolizers (p=0.0193) and intermediate metabolizers (p=0.0016), whereas intermediate metabolizers and poor metabolizers were not statistically different from one another (p amount not reported).
Twelve patients who failed the no. row of therapy (10 extensive metabolizers, 2 intermediate metabolizers) were retreated successfully with higher dosages (rabeprazole 40 mg/day and amoxicillin 2000 mg/day) for 2 weeks.
As with the point age bracket scrutiny, this contemplation showed that dual rabeprazole-amoxicillin therapy was affected by CYP2C19 make-up position, and high-dose dual therapy was necessary for extensive metabolizers.
Contrasting findings emerged from an additional people scrutiny, which involved 150 Nipponese patients (78% men, mean age 49.4 ± 0.9 yrs) who were film for H. pylori and had peptic ulcer disease or nonulcer dyspepsia. The aid care was a 1-week facility of omeprazole 40 mg/day, amoxicillin 1500 mg/day, and clarithromycin 400 mg/day.
Genotyping revealed 61 extensive metabolizers, 61 intermediate metabolizers, and 28 poor metabolizers.
The work-clothes cure rate was 86% (95% CI 79-91%).
There were no significant differences in H. pylori cure rates among the extensive and intermediate metabolizers versus the poor metabolizers (OR 0.593, 95% CI 0.126-2.774, p=0.74).
