|Official Title:||Efficacy of Seven-day Combined Rabeprazole Plus Levofloxacin Plus Augmentin for Eradication of Helicobacter Pylori.|
- Eradication Rate (Participants Naive to Anti-H. Pylori Treatment) [ Time Frame: 4 weeks after complete use of drug for treatment ]A negative post-treatment 13C-urea breath test or CLO test result at more than 4 weeks after complete use of drug for treatment.
- Eradication Rate of Participants Living in Rural Area. [ Time Frame: 4 weeks after complete use of drug for treatment ]Subgroup analysis on eradication rate (percentage of participants with a negative result of C13 or CLO test at least four weeks after treatment) according to resident area of participants, especially who are living in rural area.
- Re-eradication Rate [ Time Frame: 4 weeks after complete use of drug for treatment ]Re-eradication successful rate (percentage of participants with a negative result of C13 or CLO test at least four weeks after the 2nd treatment) with 7-day levofloxacin, amoxicillin/clavulanate and rabeprazole for patients still with Hp infection previously treated with regimen without levofloxacin and Augmentin.

7-day levofloxacin, amoxicillin/clavulanate, rabeprazole for Hp eradication.
Levofloxacin, 500 mg b.i.d., amoxicillin/clavulanate, 875mg/125mg b.i.d. and rabeprazole, 20 mg b.i.d. for 7 days.
Active Comparator: Clarithromycin-Amoxicillin
7-day clarithromycin, amoxicillin, rabeprazole for Hp eradication.
Clarithromycin, 500 mg b.i.d., amoxicillin, 1000 mg b.i.d. and rabeprazole 20 mg b.i.d. for 7 days.
The resistance rate of Helicobacter pylori (Hp) to amoxicillin and metronidazole therapy is significantly higher in Eastern Taiwan as compared to national and worldwide rates. The high resistance rate in this territory justified a search for a better eradication regimen for Hp infection.
To evaluate the efficacy and tolerability of a combination therapeutic regimen of levofloxacin, amoxicillin/clavulanate and rabeprazole (LAcR) versus a conventional seven-day triple therapy with clarithromycin, amoxicillin and rabeprazole (CAR) for the eradication of Hp infection.
We conducted a open-labeled, prospective, randomized, controlled study in a large tertiary referral hospital in Eastern Taiwan. Hp-positive therapy-naïve patients with a positive CLO test as proven by gastroscopy were recruited for potential random assignment to two 7-day treatment groups: LAcR or CAR (control). The primary end point of this study was to evaluate the eradication rate of LAcR regimen. Hp eradication was assessed using the 13C-urea breath test or CLO test performed at least 4 weeks after end of treatment. Compliance and adverse effects with therapy were determined by phone call or outpatient clinic follow up.
The seven-day LAcR regimen evaluated in this study provided improved Hp eradication efficacy when compared with the traditional seven-day triple therapy in Eastern Taiwan.
