Brief Summary:
This study is designed to compare the eradication rates,safety and compliance of tailored therapy to those of standard triple therapy in children with H. pylori infection. The primary purpose is to compare the eradication rates of children with H. pylori infection treated with tailored therapy to those treated with standard triple therapy. The secondary purpose is to evaluate the safety, compliance and factors that might affect eradication rates.

Condition or disease Intervention/treatment Phase
Helicobacter Pylori Infection Drug: Tailored Group Drug: Standard group Phase 4

Detailed Description:
Between March 2014 and March 2016, 200 children with upper gastrointestinal symptoms (4-18 years) and H. pylori infection will be recruited at Beijing Children Hospital.After the informed consents are obtained from the guardians, the children will be randomly classified into the two group: 10 days standard triple therapy (Omeprazole 0.8-1.0mg/kg.d,bid, Amoxicillin 30-50mg/kg.d bid, Clarithromycin 15-20mg/kg.d bid), or 10 days tailored therapy including one Proton Pump Inhibitor ( Rabeprazole 0.4-0.5mg/kg.d,bid. or Esomeprazole 0.8-1.0mg/kg.d,bid) and two antibiotics (Amoxicillin 30-50mg/kg.d bid, Clarithromycin 15-20mg/kg.d bid, Metronidazole15-20mg/kg.d bid) based on antibiotics susceptibility and cytochrome P450 isoenzyme 2C19 genotype. Eradication status will be reassessed in four weeks after treatment.

Official Title: Tailored Therapy Versus Standard Triple Therapy for Helicobacter Pylori Eradication in Children: A Randomized Trial
Study Start Date : March 2014
Estimated Primary Completion Date : March 2016
Estimated Study Completion Date : July 2016

Arm Intervention/treatment
Experimental: 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.
Drug: 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.

  • "Amoxicillin""Tongdamoxing®"

Active Comparator: 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.
Drug: 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) .
Other Names:
  • "Omeprazole"" LosecMUPS®"

  • "Clarithromycin""Klacid®"

Primary Outcome Measures :
  1. Compare the eradication rates in each group [ Time Frame: One month after treatment ]
    The efficacy of H. pylori eradication between the standard triple therapy and tailored therapy based on the results of antimicrobial resistance(including Clarithromycin sensitivity) by using H. pylori culture and cytochrome P450 isoenzyme 2C19 genotype. Eradication status will be reassessed in one month after treatment.

Other Outcome Measures:
  1. Compare the adverse reactions in each group [ Time Frame: Three months ]
