About this study
Official title: The Efficacy of the Culture Based Tailored Therapy for Helicobacter Pylori Eradication Comparing With the Traditional 2nd Line Rescue Therapy in Korean
As increasing the antibiotics resistance, the effectiveness of traditional Helicobacter pylori (H. pylori) therapies has been declined coincidently. In this study, the investigators evaluated the efficacy of H. pylori eradication between a personalized therapy for H. pylori infection based on the results of antibiotics resistance by using H. pylori culture and minimal inhibitory concentration (MIC) and the traditional 2nd rescue regimens, and the investigators analyzed the prevalence of the antibiotic resistance after 1st eradication of H. pylori in the tailored therapy group.
Read the detailed description
The patients who had shown the evidence of persistent H. pylori infection after the 1st eradication were enrolled for this study. After giving the informed consent about the method and efficacy (ITT and PP analysis) of the traditional 2nd rescue therapy and the tailored therapy for H. pylori infection based on culture and MIC, the patients were classified into the three regimen group under the patient's agreement and underwent 2nd eradication [14 days bismuth-based quadruple therapy (Proton pump inhibitor (PPI) regular dose b.i.d., tripotassium dicitrate bismuthate 300 mg q.i.d. (three tablets at 30 min before meals and one tablet at 2 hours after dinner), metronidazole 500 mg t.i.d., and tetracycline 500 mg q.i.d.), 14 days moxifloxacin-containing triple therapy (PPI regular dose b.i.d., moxifloxacin 400 mg q.d., and amoxicillin 1g b.i.d.), or tailored therapy based on H. pylori culture and MIC (select the 2nd rescue regimen between 14 days of bismuth-based quadruple therapy or 14 days moxifloxacin-containing triple therapy according to antibiotics susceptibility)].This study was analyzed the success of eradication for enrolled participants retrospectively, however the patients were enrolled prospectively based on previous study about antimicrobial susceptibility test for H. pylori in Korea.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
H. pylori culture and antimicrobial susceptibility testProcedure or surgery
Antral and body biopsy specimens were evaluated separately. Organisms were identified as H. pylori by Gram staining, colony morphology, and positive oxidase, catalase, and urease reactions. Minimum inhibitory concentrations (MICs) were determined by the agar dilution method. Amoxicillin (Sigma Chemical Co., St. Louis, Mo.), clarithromycin (Abbott Laboratories, Abbott Park, Ill.), metronidazole (Sigma), tetracycline (Sigma) and moxifloxacin (Sigma) for the H. pylori isolates were examined by use of the serial twofold agar dilution method and the reference of susceptibility testing was according to the recommendations of the Clinical and Laboratory Standards Institute [amoxicillin (AMC), MIC ≥ 0.5 μg / ml; clarithromycin (CLA), MIC > 1.0 μ g / ml; metronidazole (MET), MIC > 8 μ g / ml; tetracycline (TC), MIC > 4 μ g / ml; and moxifloxacin (MOX), MIC > 1 μ g / ml).
14 day PBMT groupDrug
Rescue therapy using 14 day PBMT regimen [Proton pump inhibitor (PPI) regular dose b.i.d., tripotassium dicitrate bismuthate 300 mg q.i.d. (three tablets at 30 min before meals and one tablet at 2 hours after dinner), metronidazole 500 mg t.i.d., and tetracycline 500 mg q.i.d]
14 day MEA groupDrug

Questions about this trial
What is this clinical trial studying?
A study testing H. pylori culture and antimicrobial susceptibility test, 14 day PBMT group and 14 day MEA group in people with Helicobacter Infection, run by Seoul National University Bundang Hospital.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 4 Oct 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants in Each Arm/Group With Successful H. Pylori Eradication (time frame: 6 weeks after completion of eradication). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02349685, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Oct 2016.
