Absence of symptomatic benefit of lansoprazole, clarithromycin, and amoxicillin triple therapy in eradication of Helicobacter pylori positive, functional (nonulcer) dyspepsia.

OBJECTIVES: The aim of this study was to compare the effect of a combination of lansoprazole, clarithromycin, and amoxicillin ( LCA) versus placebo on the severity of symptoms in functional dyspepsia patients who were positive for Helicobacter pylori (H. pylori). METHODS: This was a double-blind, randomized, controlled clinical trial in adult patients with functional dyspepsia who were H. pylori positive. Patients were randomized to 7-day treatment with LCA or identical looking placebo. H. pylori status was confirmed by the urea breath test performed at baseline, at 6 wk, and at 6 and 12 months. The severity of eight upper GI symptoms was measured on a five-point Likert scale. The main outcomes were the change in average severity of the dyspepsia summary score of the eight symptoms and the proportion of patients who improved >/=4 points on the dyspepsia summary score. RESULTS: A total of 157 patients were included in the intention-to-treat analysis. LCA achieved cure of H. pylori infection in 82% of patients compared to 6% in the placebo group. The severity of dyspepsia symptoms improved over the 12-month study period, but for none of the outcome measures was there a significant difference between LCA and placebo. CONCLUSIONS: There was no difference in sustained improvement of dyspepsia symptoms when LCA was compared with placebo. An 82% cure rate of H. pylori infection was observed with LAC.[1]
