Abstract
Objective. The findings of several studies suggest that proton-pump inhibitors (PPIs) suppress gastric acid more effectively in Helicobacter pylori-infected (Hp + ) than in non-infected (Hp − ) patients, but there has been no evaluation of the short-term clinical response. Material and methods. Results of the first week of treatment with rabeprazole in Hp+ and Hp− patients with gastroesophageal reflux disease (GERD) were compared in a large prospective open-label, multicenter, cohort study in general and specialized practices. GERD patients were recruited on the basis of either typical symptoms alone or endoscopic results, assessed for H. pylori infection and treated with rabeprazole (20 mg). Heartburn and regurgitation symptoms were assessed daily during the first 7 days. Outcome parameters were calculated for both symptoms and compared between Hp+ and Hp− patients. Results. Data on 1548 patients (74.5% Hp−, 25.5% Hp + ) were available. Mean heartburn and regurgitation scores decreased during the first week. For both symptoms, more than 70% of the patients had “adequate” symptom relief at day 5, and more than 80% at day 7. “Complete” symptom relief was reached in more than 70% of patients. Mean onset of adequate symptom control was about 4 days. In Hp+ and Hp− patients there was no difference in response for any of the parameters. Conclusions. Among patients treated with rabeprazole in clinical practice, H. pylori infection or its absence has no effect on the speed or degree of GERD symptom relief. Infected patients and non-infected patients can therefore be treated with a similar dose. When treating heartburn with rabeprazole, physicians do not need to consider the patient's H. pylori status and most patients (>80%) have adequate symptom relief after just a few days of treatment.
