Brief summary
Increasing drug resistance presents a significant challenge to the efficacies of common empiric eradication regimens for Helicobacter pylori treatment in the mainland of China. Tailored therapy may be the best choice to achieve good efficacy, especially in patients with penicillin allergy. Few studies had evaluated the patients with penicillin allergy.This study is designed to evaluate the efficacy and safety of antibiotic sensitivity-based tailored therapy for Helicobacter pylori treatment in the patients with penicillin allergy.

Intervention model description
After antimicrobial susceptibility testing of Helicobacter pylori from biopsy samples, according to antibiotic resistance pattern of each one, give esomeprazole 20mg bid, bismuth potassium citrate 600mg bid and two sensitive ones of clarithromycin, metronidazole,levofloxacin and tetracycline.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Helicobacter pylori eradication rate | Six weeks after completion of therapy | Six weeks after completion of therapy, H. pylori eradication was assessed by ¹³C-urea breath test. Eradication was defined as negative result from urea breath test (\<4‰) (4‰ as the cutoff value). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Rate of adverse effects | Within 7 days after completion of therapy | The subjects were asked to grade the severity of adverse events according to their influence on daily activities, experienced as mild (transient and well tolerated), moderate (causing discomfort and partially interfering with daily activities), or severe (causing considerable interference with daily activities) |
| Compliance rate | Within 7 days after completion of therapy | Compliance was defined as poor when they had taken less than 80% of the total medication. |
