Clinical significance of drug sensitive test for the eradication of Helicobacter pylori infection and peptic ulcer / 中国生化药物杂志

ABSTRACT

Objective To explore the value of Helicobacter pylori( Hp) drug sensitivity test for clinical treatment of Hp infection and peptic ulcer. Methods Selected from February 2013 to October 2014 gastroenterology clinic in the hospital inpatient treatment and 120 patients( Steering Group) , of which 69 cases of gastric ulcer, duodenal ulcer 51 patients, mucosal lesions in patients took tissue culture Hp, Hp strain cultured to antibiotic susceptibility testing by disk diffusion method and based on susceptibility testing to guide treatment , alternative 120 cases of peptic ulcer patients as a routine group, ulcer treatment effect was observed between two groups and Hp eradication therapy.Results Steering group of 120 patients, 75 patients were successfully cultured Hp, susceptibility test results: the most sensitive to gentamicin(94.67%), followed furazolidone(88.00%), the lowest sensitivity to metronidazole(8.00 %);reviewed 4 weeks after treatment, ulcer healing rate of steering group of patients 93.33% was significantly higher than the end of treatment 4 weeks after the ulcer healing rate of regular group of 81.67%, steering group of patients with abdominal pain short time (3.5 ±1.5)d was significantly shorter than conventional group of patients(4.3 ±1.7) d; Hp eradication of steering group patients was 89.17%significantly higher than conventional group were 78.33% and the difference was statistically significant ( P<0.05 ) .Conclusion According Hp susceptibility testing, can choose Hp sensitive proton pump inhibitor combination of antibiotics amoxicillin treatment, can achieve more significant clinical effect.
