Abstract

Background/aims: Conventional triple therapy (CT) for Helicobacter pylori infection fails in up to one-third of patients. Sequential therapy (ST) seem be more effective than CT in other countries. However, there is no systemic literature review that directly compares CT and ST in Korea. The aim of this study was to compare ST with CT for H. pylori infection in Korea.

Methods: Six randomized, prospective controlled trials were used to compare 10-day ST and 7- to 14-day CT in treatment-naive patients with documented H. pylori infection in Korea. Pooled eradication rates and OR with 95% CI were calculated.

Results: The intention-to-treat eradication rates of H. pylori involving 1,529 patients were 79.7% (95% CI, 76.8-82.5%) for ST (n=754) and 68.1% (95% CI, 64.8-71.4%) for CT (n=775) (OR, 1.838; p<0.001). The per-protocol eradication rate of H. pylori involving 1,366 patients was 86.4% (95% CI, 83.3-88.5%) for ST (n=682) and 76.0% (95% CI, 72.8-79.2%) for CT (n=684) (OR, 1.974; p<0.001).

Conclusions: Ten-day ST was superior to CT in terms of eradicating H. pylori infection. Therefore, ST should be considered as a first-line therapy in Korea. However, ST did not achieve a sufficient eradication rate. More effective therapy should be developed.
