Abstract

Background: We wanted to ascertain how Helicobacter pylori infection is managed in Scandinavia. Methods: A one-page questionnaire with seven questions was mailed in April 1998 to 1718 gastro-enterologists in Finland, Denmark, Norway, and Sweden (excluding Swedish surgeons). Results: The questionnaire was returned by 36%. Antimicrobials were used by 99% for peptic ulcer associated with H. pylori, by 67% for mucosa-associated lymphoid tissue lymphoma, by 27% before long-term therapy with a proton-pump inhibitor (PPI), by 16% for non-ulcer dyspepsia, by 11% for reflux disease, and by 11% for other indications. In Finland several conditions other than ulcer were treated more frequently than in the other countries. The commonest primary therapy is PPI triple therapy (94%), followed by bismuth-based (11%), 'other' (2%), and PPI dual therapy (0.2%). Primary bismuth-based therapy was almost completely limited to Norway. The commonest secondary therapy for failures was also PPI triple therapy (71%), followed by bismuth-based (41%), 'other' (10%), and PPI dual therapy (1%). Clarithromycin for primary therapy was used much less frequently in Finland than in the other countries. Follow-up to ascertain whether eradication is successful was done always or often by 90% in Finland, 63% in Norway, 62% in Sweden, and 21% in Denmark and by 61% of the internists and 42% of the surgeons. The commonest method to confirm eradication was gastroscopy (69%), followed by the breath test (52%) and serology (11%). Conclusions: In Scandinavia H. pylori associated with peptic ulcer disease is treated with antimicrobials by virtually all gastroenterologists. PPI triple therapy is the commonest regimen for primary and secondary eradication. PPI dual therapy has essentially disappeared. Fifty-four per cent confirm eradication always or often, with gastroscopy being the commonest method.
