Helicobacter pylori: 200 patients with a follow-up of 5 years. An observation endoscopic study.
OBJECTIVE
As data on the long-term effects of Helicobacter pylori infection are limited, our aim was to review patients seen repeatedly at endoscopy with biopsies for a minimal period of 5 years.


METHODS
The records of 200 patients who had at least two endoscopic examinations with antral biopsies and touch cytology (imprints from biopsies) with an interval of at least 60 months between the first and the last endoscopy. Helicobacter pylori diagnosis was based on the smear.


RESULTS
At the first endoscopy, 57% had Helicobacter pylori on the smear, 70% had chronic gastritis on biopsy. During a mean follow-up of 70 months, a colonization rate of 3% per year and an eradication rate of 1% per year were observed. Helicobacter pylori status remained unchanged in 89%. During follow-up, duodenal ulcer was diagnosed at endoscopy in 21 patients, with a significantly (p < 0.05) higher frequency in Helicobacter pylori positive patients, in the presence of gastritis and in men. In two patients, the sequence of colonization and later duodenal ulcer was observed.


CONCLUSIONS
Our retrospective observation study based on endoscopy confirms the chronicity of Helicobacter pylori infection and the low incidence of colonization and eradication. Duodenal ulcer occurred more frequently in Helicobacter pylori positive patients.
