Infection with Helicobacter pylori is accepted as the primary cause of peptic ulcer disease, and there is evidence to suggest its role in other gastrointestinal disorders. An estimated 20% to 40% of the Canadian population is infected with H pylori; however, clinically relevant disease is present in only approximately 10% to 20% of these individuals. Therefore, it is crucial to identify the diseases for which eradication of H pylori is beneficial to ensure that patients do not receive unnecessary treatment. In patients with ulcers induced by long term treatment with nonsteroidal anti-inflammatory drugs, preliminary results suggest that eradication of H pylori may reduce the risk of peptic ulcer bleeding. Furthermore, a benefit has been observed for the eradication of H pylori before patients commence therapy with a nonsteroidal anti-inflammatory drug. An association between the presence of H pylori and specific dyspeptic symptoms has yet to be established; however, there may be a subset of patients with functional dyspepsia who benefit from the eradication of H pylori. The relationship between gastroesophageal reflux disorder and H pylori infection remains unclear. In Canada, the recommended therapy for the eradication of H pylori is seven days of twice-daily treatment with a proton pump inhibitor, clarithromycin, and amoxicillin or metronidazole. Although the proton pump inhibitors are treated as a class for use in these regimens, there is suggestion that a faster onset of action may lead to a higher rate of eradication.
