Smoking and Drinking Habits Are Important Predictors of Helicobacter Pylori Eradication

D B Namiot et al. Adv Med Sci.


Purpose: The aim of the study was to evaluate the effect of smoking and drinking habits, in separate and joint analyses, on the efficacy of H. pylori eradication.

Materials and methods: A total of 250 patients were recruited. They were treated with a 7-day course of omeprazole, amoxicillin, tinidazole (OAT), omeprazole amoxicillin, clarithromycin (OAC) or omeprazole, clarithromycin, tinidazole (OCT). The efficacy of H. pylori eradication was tested with a CLO-test and histology 4 weeks after the completion of antibacterial therapy.

Results: Drinking was found not to affect the efficacy of H. pylori eradication in any therapeutic group, while smoking decreased it in the OAC group (smokers 69.6%, non-smokers 94.3%, p=0.006). In the OAT treated group H. pylori eradication rate was lower in smokers-non-drinkers than in smokers-drinkers and non-smokers-non-drinkers (38.9% vs 83.2% and 70.0%, p=0.002 and p=0.034, respectively), while in the OAC treated group, smokers-non-drinkers had lower eradication efficacy than non-smokers-drinkers and non-smokers-non-drinkers (59.1% vs 100% and 91.3%, p=0.01 and p=0.012, respectively). In the OCT treated group, differences between subgroups were not significant.

Conclusions: Smoking and drinking habits when analyzed jointly are more useful to predict the outcome of H. pylori eradication than when analyzed separately.
