Yet a maverick is now arguing that H pylori may have some benefits as well, and so he warns that a wholesale campaign to eradicate the bacterium is premature.
The debate about whether H pylori is good or bad needs immediate attention because the bacterium is a "submerging"--rather than emerging--infection, Blaser says.
A few studies have begun to differentiate the effects of H pylori on different segments of the gastrointestinal tract.
He thinks the rise is lagging 20 to 30 years behind declines in H pylori infection.
Seven strategies are modeled: empiric antisecretory therapy; empiric H pylori eradication using oral omeprazole (500 mg twice daily), clarithromycin (500 mg twice daily), and amoxicillin (1000 mg twice daily); use of either upper endoscopy, an upper gastrointestinal barium study (an upper GI), or the serum titer for H pylori as a diagnostic test to identify patients for H pylori eradication; or use of an initial diagnostic test followed by the serum titer for H pylori.
Three strategies were similarly cost-effective: empiric H pylori eradication ($1198 per QALY), use of a serum H pylori titer as an initial diagnostic test ($1214 per QALY), and empiric antisecretory therapy ($1288 per QALY).
This cost-utility analysis suggests that two strategies are reasonable for patients presenting with dyspepsia: (1) empiric H pylori eradication and (2) use of a serum H pylori titer to identify patients who might benefit from H pylori eradication.
