Brief summary
H.pylori is an organism which causes gastric inflammation, peptic ulcer disease (PUD), mucosa associated lymphoid tissue (MALT) lymphoma and gastric cancer. Practical guideline for treatment of patients with dyspepsia and H.pylori eradication recommended the 14-day triple therapy regimen which had curable about 70% by using proton pump inhibitor (PPI) combined with antibiotics including amoxicillin, clarithromycin and metronidazole. Up to date, there has been no evidence about the cure rate for H.pylori eradication with once-daily dose regimen of high dose rabeprazole and levofloxacin based therapy. This research is to study the 7-day and 14-day cure rate of H.pylori eradication treatment with once-daily regimen of high dose rabeprazole-levofloxacin based quadruple therapy.
Interventions
DIAGNOSTIC_TEST13C Urea Breath Test
After the H.pylori eradication treatment course completed, participants then was tested with 13C Urea Breath Test to confirm treatment effectiveness at least after ceasing PPI and antibiotics for 4 weeks.

Intervention model description
Participants with positive rapid urease test or pathologic findings were divided into 2 groups and enrolled into randomization with 1:1 block of four methods. Each participant in group1 received 7-day once daily dose regimen of 1-tablet 750-mg Levofloxacin after meal, 2-tablet 500-mg Clarithromycin MR after meal, 3-tablet 20-mg Rabeprazole before meal and 1-tablet 1,048-mg Gastro bismol after meal. Meanwhile, each participant in group2 received 14-day once daily dose regimen of 1-tablet 750-mg Levofloxacin after meal, 2-tablet 500-mg Clarithromycin MR after meal, 3-tablet 20-mg Rabeprazole before meal and 1-tablet 1,048-mg Gastro bismol after meal.

| Measure | Time frame | Description |
|---|---|---|
| To measure eradication rate of participants with once-daily dose regimen of 14-day rabeprazole-levofloxacin based quadruple therapy for H. pylori eradication by Urea Breath Test in Thai patients with non-ulcer dyspepsia | 6 weeks | Participants with positive rapid urease test or pathologic findings evidenced for H.pylori received 14-day once daily dose regimen. After the H.pylori eradication treatment course completed, participants then was tested with 13C Urea Breath Test to confirm the effectiveness of the treatment at 4 weeks. Eradication rate was defined as proportion of post-treatment cases with negative urea breath test compared to pre-treatment cases with positive rapid urease test or pathologic findings evidenced for H.pylori. |
| To measure eradication rate of participants with once-daily dose regimen of 7-day rabeprazole-levofloxacin based quadruple therapy for H. pylori eradication by Urea Breath Test in Thai patients with non-ulcer dyspepsia | 5 weeks | Participants with positive rapid urease test or pathologic findings evidenced for H.pylori received 7-day once daily dose regimen. After the H.pylori eradication treatment course completed, participants then was tested with 13C Urea Breath Test to confirm the effectiveness of the treatment at 4 weeks. Eradication rate was defined as proportion of post-treatment cases with negative urea breath test compared to pre-treatment cases with positive rapid urease test or pathologic findings evidenced for H.pylori. |
