Correlation of serum pepsinogen with histological atrophy following successful Helicobacter pylori eradication: PEPSINOGEN AND HISTOLOGICAL FINDINGS AFTER H. PYLORI ERADICATION

Levels of pepsinogen have been reported to correlate with the degree of gastric atrophy in Helicobacter pylori‐infected gastric mucosa.

Correlation between serum pepsinogen levels and gastric mucosal histological findings before and after Helicobacter pylori eradication therapy

Background:  Helicobacter pylori causes chronic gastritis and is also associated with many other gastrointestinal diseases. The incidence of gastric cancer is thought to vary according to the degree and topography of chronic gastritis. Histological findings of specimens obtained at endoscopy are therefore important. In the present study, we investigated the correlation between these histological findings and serum pepsinogen (PG) levels.

Comparison of efficacies of dual therapy and triple therapy using rabeprazole in second-line eradication of Helicobacter pylori in Japan: SECOND-LINE HELICOBACTER PYLORI ERADICATION REGIMENS

The only authorized second‐line Helicobacter pylori regimen in Japan is proton pump inhibitor + amoxycillin + clarithromycin. However, it has been reported that this second‐line regimen is not effective. In this study, we evaluated the efficacy of dual and triple eradication therapies using rabeprazole as second‐line H. pylori eradication regimens.
