Background: The prevalence both of Helicobacter pylori infection and oesophagitis is higher in the elderly, than in adult and young populations. However the relationship between Helicobacter pylori infection and the clinical behaviour of oesophagitis has not yet been clarified.
Aim: To evaluate the influence of Helicobacter pylori infection on the severity and clinical outcome after treatment of oesophagitis in elderly patients.
Methods: A total of 271 elderly patients (134 male, 137 female, mean age = 79.2 years, range 65-96) with grade 1 to 3 oesophagitis were studied. At baseline, the patients were divided into 3 groups according to Helicobacter pylori infection: Group 1 = 88 Helicobacter pylori-negative patients; Group 2 = 59 Helicobacter pylori-positive patients and Group 3 = 124 Helicobacter pylori-positive patients who underwent a one-week proton pump inhibitor-based triple therapy for the eradication of Helicobacter pylori infection. All patients were treated with proton pump inhibitors for two months; patients in Group 3 were also treated for one week with proton pump inhibitors plus two antibiotics. After two months, endoscopy and histology were repeated.
Results: At baseline, 32.5% of patients were Helicobacter pylori-negative and 67.5% were Helicobacter pylori-positive. No baseline differences in severity of oesophagitis were found between Helicobacter pylori negative and positive patients. After proton pump inhibitor therapy, the complete resolution of oesophagitis was observed in 80.7% of Group 1, 76.3% of Group 2 and 75.8% of Group 3 (p=ns). Dividing patients also according to the severity of oesophagitis, no difference in healing rates between the three Groups were observed.
Conclusions: In this elderly population, Helicobacter pylori infection did not influence the severity of oesophagitis at baseline or the response to short-term treatment with proton pump inhibitors. Furthermore, Helicobacter pylori eradication therapy did not influence the healing rate of oesophagitis.
