To determine the effect of smoking on Helicobacter pylori eradication and ulcer healing, we investigated 232 patients with H. pylori-positive duodenal ulcer. Patients were given one of seven different treatment protocols and divided into three groups according to smoking habits. Group 1 (n = 128) consisted of non-smokers, group 2 (n = 65) of mild smokers (5-20 cigarettes/day) and group 3 (n = 39) of heavy smokers (> 20/day). The eradication of H. pylori and ulcer healing rate was controlled eight weeks later after ceasing the therapy. The overall eradication rate was 66% in all patients and 68%, 66%, 59% in each group, respectively. The eradication rates showed no statistical difference between groups. Complete ulcer healing was achieved in 84% of all patients and ulcer healing rate between groups did not show any significance (85%, 83% and 82% respectively). These results suggest that smoking status does not influence the eradication of H. pylori and duodenal ulcer healing rates at eight weeks in patients on different treatment schedules.
