Clinical research of sequential therapy for Helicobacter pylori-infected patient

Objective To observe the efficacy for the eradication of Helicobacter pylori (Hp) by using the 10-day sequential therapy consisting of omeprazle,amoxicillin,clarithromycin,and furazolidone,and to compare with the traditional triple-drug therapy.Methods 155 adult patients,who were Hp positive with peptic ulcer,chronic gastritis with mucosal atrophy or erosion,were selected and randomly divided into two groups.The patients in 10-day sequential therapy group received omeprazole and amoxicillin in the first 5 days followed by another 5 days of ome-prazole,clarithromycin and furazolidone.The patients in traditional triple-drug therapy group recieved omeprazole,amoxicillin,and clarithromycin for 7 days.Results The HP eradication rate of the 10-day sequential therapy group was 92.31% ,while the traditional triple-drug group was 72.73%.The difference between the two groups was statistically significant (P<0.01).Conclusion The 10-day sequential therapy consisting of omeprazole,amoxicillin,clarithromycin and furazolidone achieved higher eradication rate,and it was safe,and good compliance.
