Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Tailored Group
In tailored therapy, medications will be adjusted according to the antimicrobial susceptibility testing (including Clarithromycin sensitivity) and cytochrome P450 isoenzyme 2C19 genotype. 10 days regimen will be prescribed.
Tailored Group
All the patients who enrolled in this arm will be received endoscopy followed by biopsy for antimicrobial susceptibility testing and cytochrome P450 isoenzyme 2C19 genotype. 10 days tailored therapy will be given including one Proton Pump Inhibitor ( Rabeprazole0.4-0.5mg/kg.d,bid. or Esomeprazole0.8-1.0mg/kg.d,bid) and two antibiotics (Amoxicillin30-50mg/kg.d bid, Clarithromycin15-20mg/kg.d bid, Metronidazole15-20mg/kg.d bid ) based on the cytochrome P450 isoenzyme 2C19 genotype and the antimicrobial susceptibility.
Standard group
In standard triple therapy, children will be treated by Omeprazole(0.8-1.0mg/kg.d,bid), Amoxicillin (30-50mg/kg.d bid)and Clarithromycin (15-20mg/kg.d bid) for 10 days.
Standard group
All the patients who enrolled in this arm will be treated by Omeprazole(0.8-1.0mg/kg.d,bid), Amoxicillin (30-50mg/kg.d bid)and Clarithromycin (15-20mg/kg.d bid) .
