Helicobacter pylori infection remains an important cause of morbidity and mortality worldwide. Attempts at developing a vaccine have failed, and the current focus for clinicians is the treatment of the infection. Eradication of H pylori has been shown to prevent recurrent peptic ulcer disease, to cure some localized gastric mucosa–associated lymphoid tissue lymphomas, and to prevent nonsteroidal anti-inflammatory drug (NSAID)–related ulcers in patients who are initiating long-term NSAID therapy.1 In recent years, the rate of treatment failure associated with established drug regimens has increased at a rapid rate.2
