OBJECTIVE
To re-examine the efficacy and tolerability of 1-week proton pump inhibitor triple therapy as a first-line Helicobacter pylori (H. pylori) eradication therapy.
METHODS
Consecutive participants with a positive rapid urease test during an outpatient upper endoscopy were included. All participants were given pantoprazole 40 mg b.i.d., amoxycillin 1 g b.i.d. and clarithromycin 500 mg b.i.d. for 1 week. They were asked to return after 1 week to report any side effects related to the medications and to check for compliance. Successful eradication was defined by negative (13)C-urea breath test at least 4 weeks after the completion of therapy.
RESULTS
A total of 191 patients were recruited into the study, of whom 81 were male (42.4%) and 110 female (57.6%), with a mean age of 55.6 (range 21-88) years. Overall 26 patients (13.6%) defaulted follow up and five patients were not compliant (taking less than 85%) with the medications. Per-protocol and intention-to-treat eradication rates were 84.4% (95% CI: 78.6-89.9%) and 71.2% (95% CI: 64.5-77.6%), respectively. Overall 68 participants (42.5%) reported no side effects, followed by 58 (36.3%) with a taste disturbance, 16 (10.0%) with epigastric pain, 15 (9.4%) with diarrhea, 13 (8.1%) with nausea or vomiting, 12 (7.5%) with loss of appetite, nine (5.6%) with dizziness and two (1.3%) with an allergic skin rash, none of which was severe.
CONCLUSIONS
The current regime using pantoprazole, amoxycillin and clarithromycin is highly tolerable and effective and should continue to be recommended as a first-line therapy for H. pylori eradication in our setting.
