A post hoc subgroup analysis suggested that, in a small population of patients, heartburn symptoms will improve after H pylori eradication. The benefit of curing H pylori has been supported in other studies as well. The benefits of the test-and-treat approach are probably derived mainly from treatment of underlying ulcer disease and possibly improving a small proportion of functional dyspepsia patients . The lifetime risk in an H pylori-infected individual to develop ulcers is 5% to 15% . It is important to note that, despite successful treatment of the infection, a substantial proportion of patients (at least 50%) will require ongoing treatment for dyspepsia symptoms. In such cases, three options exist: retest for H pylori infection using a urea breath test (UBT) to ensure the infection has been cured; institute empirical therapy in accordance with the CMT recommendations; or perform endoscopy if clinically indicated, at which time biopsies for H pylori infection should be taken.

Treatment, as recommended in the CMT , consists of triple therapy with a PPI twice a day, clarithromycin 500 mg twice a day and either amoxicillin 1000 mg twice a day or metronidazole 500 mg twice a day. Recently, it has been recommended that PPI-clarithromycin-amoxicillin be used first-line because that combination is unaffected by resistance to metronidazole. Although there are limited data, the prevalence of metronidazole resistance in Canada is estimated to be approximately 20%. First-line use with a metronidazole-containing regimen is a reasonable alternative for patients with a penicillin allergy.
