Abstract:
Objective To investigate the morbidity and Helicobacter pylori (H.pylori) reinfection status within 5 years after eradication. Methods One thousand and six adults aged between 35 to 37 were selected from general population in the high incidence region of gastric cancer. Among them, 552 individuals were confirmed to be H.pylori positive by both CLO test and Warthin Starry Stain histology. All the H.pylori positive individuals were randomly divided into two groups: treatment group receiving OAC triple therapy for one week and placebo group as controls. One month after cessation of treatment, the H.pylori eradication rate was 88.9%, while in the control group the H.pylori infection rate still remained 96.4% by 13 C UBT. These subjects were endoscopically followed up at the end of first and fifth years, respectively. H.pylori infected status was studied by histology and CLO test. Results 1. At 1 and 5 years after eradication, the response rates of subjects were 89.13% and 83.11%, respectively. 2. The morbidity rates of peptic ulcer, before treatment, were 9.87% and 7.61% in the treatment group and control group, respectively. At the 1st year, the morbidity rates were 3.70% and 12.85% in the two groups ( P
