Various methods, both invasive and noninvasive, are used to verify Helicobacter pylori eradication, with varying degrees of accuracy. The purpose of this study was to verify the relationship between H pylori eradication and serum levels of pepsinogen A (PGA) and pepsinogen C (PGC). The study involved 79 patients who tested positive for H pylori infection after histologic examination and the urease test. Patients were treated with various drug regimens for 7 to 25 days. Two months after discontinuing treatment, endoscopy was performed to verify H pylori eradication; 33 of 79 patients were found to be free of infection. Venous blood samples were taken to measure PGA and PGC levels before and after treatment. Patients in whom H pylori infection was eradicated had a significant drop in PGA and PGC levels, whereas in patients with persisting H pylori infection, there was a trend in which pepsinogen levels coincided with the quantity of bacteria detected. These preliminary data suggest that it may be possible to evaluate H pylori eradication by means of serum pepsinogen levels, sparing patients a follow-up endoscopy.
