eradication of helicobacter pylori with bismuth agent quadruple and traditional chinese medicine

Conditions: Helicobacter Pylori Infection; Traditional Chinese Medicine; Eradication

Summary: this study is a prospective randomized case-control study. six hundred patients who were firstly diagnosed as helicobacter pylori infection will be selected, and then randomly assigned into case group and control group. patients in control group take bismuth quadruplicate for 14 days. patients in case group take ban xia xie xin decoction and bismuth agent quadruple for 14 days. exhalation test or stool helicobacter pylori antigen detection were used to assess the eradication rate of helicobacter pylori 30 days (the 45th day) after treatment; adverse reactions were evaluated on the first day (15th day) and the 30th day (45th day) after treatment. the eradication rate of helicobacter pylori and the adverse drug reactions during the medication will be evaluated. the effect of ban xia xie xin decoction and bismuth quadruple based on furazolidone on the eradication of helicobacter pylori infection will be explored.

helicobacter pylori is a primary carcinogen of gastric cancer. helicobacter pylori infection rate is about 50% in china. helicobacter pylori infection should be eradicated unless there are countervailing factors. the bismuth agent quadruple (ppi+bismuth pectin+2 kinds of antibiotics) has eradicated the first line therapy of h. pylori infection. the rise of antibiotic resistance rate leads to the decline of eradication rate of h. pylori. traditional chinese medicine played an important role in the treatment of h. pylori infection. this study explored the application of ban xia xie xin decoction and bismuth agent quadruple based on furazolidone in the role of the eradication of h. pylori infection. this study is a prospective randomized case-control study. six hundred patients who were firstly diagnosed as helicobacter pylori infection will be selected, and then randomly assigned into case group and control group. the case group was named as traditional chinese medicine group. patients in the case group will take ban xia xie xin decoction and bismuth quadruplicate for 14 days. the control group was named as bismuth quadruplicate group. patients in the control group will take bismuth quadruplicate for 14 days. bismuth quadruplicate includes esomeprazole (nexium 20mg bid), amoxicillin (amoxicillin 1.0 bid), furazolidone (100mg bid) and pectin bismuth gel (150mg qid). ban xia xie xin decoction includes 10g of banxia, 10g of huangqin, 6g of coptis chinensis, 6g of dried ginger, 6g of ginseng, 6g of roasted licorice, 6g of chinese jujube. one dose in the morning and one dose in the evening, and take after meals. exhalation test or stool helicobacter pylori antigen detection were used to assess the eradication rate of helicobacter pylori 30 days (the 45th day) after treatment; adverse reactions were evaluated on the first day (15th day) and the 30th day (45th day) after treatment. the eradication rate of helicobacter pylori and the adverse drug reactions during the medication will be evaluated. the effect of ban xia xie xin decoction and bismuth quadruple on the eradication of helicobacter pylori infection will be explored.
