ABSTRACT
Factors influencing Helicobacter pylori infection recurrence still have not been fully clarified. The aim of this study was to determine whether, after eradication of H. pylori, any clinical or histologic features could yield information on infection relapse. We enrolled in the study 72 patients successfully treated for H. pylori infection by either dual (n = 49) or triple (n = 23) therapy. H. pylori eradication was defined as a negative bacterial finding by rapid urease test and histologic assessment at least 4 weeks after cessation of therapy. Upon eradication, gastritis grading was performed and patients were asked to return for an endoscopic control 6-8 months later. The recurrence of H. pylori infection was observed in 12 of 72 (16.7%) patients. The infection recurrence rate resulted significantly higher in nonulcer dyspepsia patients (p = 0.01 ) and in women (p = 0.03), whereas infection relapse did not differ between patients treated with dual or triple therapy. There was a strong (p = 0.0001 ) relationship between the persistence of chronic active gastritis after H. pylori eradication and recurrence of infection, whereas gastritis grade and metaplasia were not related to recurrence. In conclusion, this study found that H. pylori infection recurrence after successful dual or triple therapy is fairly high and that gastroduodenal disease, gender, and gastritis activity seem to affect infection relapse.
