    Abstract:
    OBJECTIVES: The aim of this study was to assess the still controversial role of treatment of Helicobacter pylori (H. pylori) infection in patients with nonulcer dyspepsia. METHODS: We conducted a double-blind, randomized, placebo-controlled, multicenter trial comparing the efficacy of 7 days of eradication treatment (lansoprazole 15 mg b.i.d., amoxicillin I g b.i.d., and clarithromycin 500 mg b.i.d.) with a control treatment (lansoprazole 15 mg b.i.d. and placebo) in H. pylori-infected patients with nonulcer dyspepsia. 13C breath tests were performed at baseline and during follow-up. We assessed patient symptoms, health status (based on the SF-12 questionnaire), patient satisfaction, drug consumption, health care consultation behavior, and absenteeism related to dyspepsia over a 1-yr period. RESULTS: A total of 74 patients randomized to eradication treatment and 70 patients randomized to placebo were compared. The rate of eradication of H. pylori infection was 75% in the active treatment group and 4% in the placebo group (p < 0.005). The symptom score improved to a similar extent in the group receiving active treatment (-4.0; 95% CI = -5.0 to -3.0) and placebo (-3.6; 95% CI = -4.5 to -2.7). Treatment response was not related to the severity or duration of initial symptoms or to the severity of gastritis on histology. Quality of life scores were comparable at 12 months. There was no significant difference in dyspepsia-related absenteeism or satisfaction with management of NUD. Patients receiving active treatment were more likely not to have had to use any dyspepsia treatment over the 12 months (60.8% vs 44.3%; p = 0.047). CONCLUSIONS: This study did not demonstrate any substantial benefit of curing H. pylori infection in patients with nonulcer dyspepsia. The study adds further evidence that H. pylori is not the main pathogenetic or therapeutic target in these patients.
