[The effect of cigarette smoking and alcohol consumption on efficacy of Helicobacter pylori eradication].
None of the drug regimens used to treat H. pylori infection ensures 100% of efficacy. One may think therefore that among factors modifying H. pylori eradication there are also cigarette smoking and alcohol consumption. The aim of the study was to determine the influence of cigarette smoking and alcohol consumption on efficacy of H. pylori eradication. The study was conducted on 142 H. pylori positive peptic ulcer patients treated with either OAT-omeprazole (2 x 20 mg), amoxycillin (2 x 1000 mg), tinidazole (2 x 500 mg) (69 patients) or OAC-omeprazole (2 x 20 mg), amoxycillin (2 x 1000 mg), clarithromycin (2 x 250 mg) (73 patients). Detailed information on smoking and drinking habits was obtained from a questionnaire fulfilled by all subjects. Patients were defined as smokers if smoked 5 or more cigarettes per day and as drinkers if drank 25 g or more alcohol per week. To enter the study patients had to have confirmed H. pylori infection by two tests (CLO-test and histology). Eradication was considered successful if both tests gave negative results 4-6 weeks after the cessation of treatment. The efficacy of H. pylori eradication was similar in both groups (OAT--69.6%, OAC--78.1%). Patients who smoked cigarettes had lower rate of H. pylori eradication in OAC group (smokers 65.8%, non-smokers 91.4%, p < 0.01), while patients who drank alcohol had higher eradication rate in OAT group (drinkers 85.2%, non-drinkers 59.5%, p < 0.05). When two factors (smoking, drinking) were analyzed together, it was found that in drinkers treated with OAT, smoking did not change the efficacy of H. pylori eradication, while in non-drinkers decreased by two times (75.0% vs 38.9%, p < 0.02). In drinkers treated with OAC, smoking did not change the efficacy of H. pylori eradication (but this was likely related to the limited number of patients), while decreased it in non-drinkers from 90.0% to 65.2% (p < 0.05). When two groups were analyzed together (OAT + OAC), the lowest efficacy of H. pylori eradication exhibited smokers who do not drink (53.7%) followed by smokers who drink (75.8%), non-smokers who do not drink (83.3%) and non-smokers who drink (92.9%); in each case the efficacy of eradication was higher than in smokers who do not drink (p < 0.05, p < 0.01, p < 0.01, respectively). Both cigarette smoking and alcohol consumption can affect the efficacy of H. pylori eradication. Smoking and drinking habits should be taken into account, when the set of drugs for H. pylori eradication is chosen.
