Aim:
To compare the efficacy of pantoprazole vs. a one‐week Helicobacter pylori eradication therapy for the prevention of NSAID‐related gastroduodenal damage.
Methods:
Patients over 60 years old with symptoms and/or a history of ulcer who needed NSAID treatment were evaluated by endoscopy. H. pylori positive subjects who had no severe gastroduodenal lesions were randomized to take, concomitantly with NSAID therapy, either: (i) pantoprazole 40 mg daily plus amoxycillin 1 g b.d. and clarithromycin 250 mg b.d. for 1 week (35 subjects, Group PAC) or (ii) pantoprazole 40 mg daily for 1 month (34 subjects, Group P). Endoscopy was repeated after 1 month.
Results:
A significantly higher incidence of severe gastroduodenal damage was found in Group PAC than in Group P (29% vs. 9%, P < 0.05). The percentages of patients worsened, unchanged and improved after 1 month were, respectively: Group PAC: 46%, 46%, and 9% and Group P: 7%, 65%, and 29% (P < 0.0008). The percentage of H. pylori‐negative subjects was 89% in Group PAC and 52% in Group P (P=0.0009). The incidence of gastroduodenal damage was higher in Group PAC treatment failures than in cured patients (50% vs. 25.8%, P=ns).
Conclusion:
One month of pantoprazole was more effective than a proton pump inhibitor‐based triple therapy in the prevention of gastroduodenal damage in elderly H. pylori‐positive NSAID users.
