Ingen indgriben: H. pylori negative group

Andet: H. pylori positive and successful eradication group
H. pylori-positive patients are given rabeprazole 10mg + amoxicillin 1000mg + clarithromycin 500mg + colloidal bismuth tartrate 220mg bid for 14 days.
After 4-6 weeks of completing eradication therapy, 13C-UBT is performed and the result show that H. pylori is eradicated.
At the same time, Patients with successful eradication are instructed to conduct 13C-UBT examination after 6 months,1year and every year after drug withdrawal.
|
Among these outpatients, H. pylori-negative patients don't give any intervention.
But H. pylori-positive patients are given rabeprazole 10mg + amoxicillin 1000mg + clarithromycin 500mg + colloidal bismuth tartrate 220mg bid for 14 days.
After 4-6 weeks of completing eradication therapy, 13C-UBT is performed.

Andet: H. pylori positive and eradication failure group
H. pylori-positive patients are given rabeprazole 10mg + amoxicillin 1000mg + clarithromycin 500mg + colloidal bismuth tartrate 220mg bid for 14 days.
After 4-6 weeks of completing eradication therapy, 13C-UBT is performed and the result show that H. pylori is not eradicated.

Tidsramme |
|---|---|---|
|
Infection rate
Tidsramme: 1 year
|
The infection rate is defined as the proportion of patients diagnosed positive among all subjects undergoing 13-UBT.(On the 13-UBT,if the result DOB≥4.
0‰, it can be determined that the subject is H. pylori positive; DOB <4.
0‰,the subject is H. pylori negative)
|
1 year
|
|
The Affecting factors of Helicobacter pylori infection is investigated by questionnaire statistics.
Tidsramme: 1 year
|
The questionnaire refers to "National Helicobacter pylori Research Questionnaire", which is designed by the Department of Epidemiology and Health Statistics, Peking University School of Medicine.And the questionnaire includes general situation, basic situation, living environment and living habits, personal disease history, related symptoms,and family history, etc.Through logistic regression analysis to calculate OR value and P value, to understand the relationship between Helicobacter pylori infection and the factors involved in the questionnaire.

Eradication rate
Tidsramme: 1 year
|
H. pylori-positive patients are given PPI quadruple therapy,and after 4-6 weeks of completing eradication therapy, 13C-UBT is performed.Eradication rate is defined as the ratio of the number of subjects who become negative after taking the eradication drug to the number of all subjects who take the eradication drug.
