Effectiveness of high-dose esomeprazole or pantoprazole 10-day sequential therapy empirically prescribed in Helicobacter pylori-infected naïve patients: a retrospective study.

Background and aim: Helicobacter pylori infection is one of the most common bacterial infections affecting humans, causing gastroduodenal and extraintestinal diseases. Treatment of the infection remains challenging for the clinicians, and different factors are involved in the failure of the therapeutic approach. The importance of the intensity of acid secretion inhibition remains an unclear issue. The aim of this study is to assess whether 80 mg/day esomeprazole-based 10-day sequential therapy (esomeprazole-ST) achieved different eradication rates when compared to 80 mg/day pantoprazole-based analogous regimen (pantoprazole-ST).

Methods: This was a retrospective observational study where data of consecutive patients referred by their physicians to our unit to perform an upper gastrointestinal endoscopy were analyzed.

Results: Overall, 1,327 patients were available for the analysis: 599 and 728 patients received pantoprazole-ST and esomeprazole-ST, respectively. Eradication rate was significantly higher in patients receiving esomeprazole-ST (92.6%, 95% CI: 91-94.5) than pantoprazole-ST (89.3%, 95% CI: 86.7-91.7; difference: 3.3%; 95% CI: 0.2-6.5; P = 0.037). Even after a multivariate analysis, the esomeprazole-ST achieved a significantly higher eradiation (OR: 1.44; 95% CI: 1.1-2.17).

Conclusions: This study showed that esomeprazole-ST achieved significantly higher H. pylori cure rates than pantoprazole-ST. Prospective and well-designed trials are demander to confirm this prelaminar finding.
