Symptom Assessment for GERD Patients Receiving H. Pylori Eradication

December 10, 2010 updated by: National Taiwan University Hospital

Symptom Assessment for Patients With Gastro-esophageal Reflux Disease Receiving Helicobacter Pylori Eradication

Background: Rebound acid hypersecretion and acid-related symptoms after discontinuation of proton-pump inhibitor has been reported in previous studies. In patients with concurrent gastro-esophageal reflux disease and Helicobacter pylori infection, whether eradication of Helicobacter pylori (H. pylori)will aggravate acid-related symptoms after discontinuation of proton-pump inhibitor remains elusive Objective: This study aims to investigate the incidence and severity of acid-related symptoms after discontinuation of proton-pump inhibitor in reflux patients receiving H. pylori eradication.

Detailed Description

Background: Rebound acid hypersecretion and acid-related symptoms after discontinuation of proton-pump inhibitor has been reported in previous studies. In patients with concurrent gastro-esophageal reflux disease and Helicobacter pylori infection, whether eradication of H. pylori will aggravate acid-related symptoms after discontinuation of proton-pump inhibitor remains elusive Objective: This study aims to investigate the incidence and severity of acid-related symptoms after discontinuation of proton-pump inhibitor in reflux patients receiving H. pylori eradication Patients and methods: Consecutive reflux patients documented by validated questionnaires (GerdQ) and upper endoscopy will be enrolled from the outpatient clinic. After determination of H. pylori status by urea breath test, those with positive H. pylori infection will be randomized into two groups. Group A (n=100) will be given initial H. pylori eradication with triple therapy for one week, followed by proton-pump inhibitor (PPI) with rabeprazole 20 mg qd for 7 weeks. Group B (n=100) will be given rabeprazole 20 mg qd for 8 weeks and discontinued for 2 weeks. Then, H. pylori eradication with triple therapy will be given for one week, followed by rabeprazole 20 mg qd for 7 weeks. For patients with negative H. pylori infection (n=100), proton-pump inhibitor with rabeprazole 20 mg qd will be given for 8 weeks and discontinued. The incidence and severity of acid-related symptoms will be evaluated with GerdQ at 2 weeks after discontinuation of PPI. The impact of H. pylori infection and H. pylori eradication on the incidence and severity of acid-related symptoms after discontinuation of proton-pump inhibitor will be analyzed.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 66 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Exclusion Criteria:

  1. Symptomatic reflux patients with high grade erosive esophagitis ( Los Angeles classification Grade C and D) or Barrett's esophagus documented by endoscopy.
  2. Symptomatic reflux patients with a history of using PPI in recent one month.
  3. Subjects with known allergy to PPI.
  4. Peptic ulcer disease
  5. Cancers of the esophagus, stomach, and duodenum

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Late eradication
Group B (n=100) will be given rabeprazole 20 mg qd for 8 weeks and discontinued for 2 weeks. Then, H. pylori eradication with triple therapy will be given for one week, followed by rabeprazole 20 mg qd for 7 weeks.
Negative HP

Early eradication
Group A (n=100) will be given initial H. pylori eradication with triple therapy for one week, followed by proton-pump inhibitor with rabeprazole 20 mg qd for 7 weeks.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
