Quantification of Serum Levels of Pepsinogens and Gastrin to Assess Eradication of Helicobacter Pylori

We investigated whether serum levels of pepsinogen (sPG)I and sPGII, the ratio of sPGI to sPGII, or serum levels of gastrin-17 (sG17), can be used to assess eradication of Helicobacter Pylori 8 weeks after treatment.We performed a prospective study of 228 consecutive patients with H pylori infections. At the start of the trial (baseline), patients were assessed using the (13)C-urea breath test ((13)C-UBT) and endoscopy, and serum levels of...
