Analysis of Helicobacter pylori infection in different groups of population in Yangzhou / 国际检验医学杂志

ABSTRACT

Objective To investigate the infection status and distribution characteristic of Helicobacter pylori (Hp)in different groups of population in Yangzhou.Methods 2 917 individuals from outpatients,hospitalized patients,and physical examination pop-ulation were recruited in the study.Serum samples from the subjects were rapidly detected using Helicobacter pylori urease antibody detection kits(Colloidal Gold method).The results were statistically analyzed.Results The totally Hp-detection rate of the 2 917 individuals was 32.9% (959/2 917).The Hp-detection rates of outpatients,hospitalized patients,and physical examination popula-tion were 33.1%,34.5% and 30.0% respectively.There were no significant difference in the positive rates between the male and female individuals(P >0.05).Overall,The Hp-positive rates increased with age.The minors(juveniles and children)had the lowest Hp-positive rate 16.0%(285/1 529);The Hp-positive rate of young adults was 34.0%(221/650),which was at the middle;elderly group had the highest Hp-positive rate 61.38%(453/758).59.8% of the patients diagnosed with gastrointestinal diseases were Hp positive.Among which,patients with peptic ulcer(74.4%)and gastric cancer(70.6%)have the highest detection rates.Some pa-tients with blood diseases,cardiovascular disease and some other diseases were also found with high Hp-detection rates.Conclusion The distribution of the Hp infection in population is positively correlated with age,but not with gender.Gastrointestinal diseases, especially peptic ulcers and gastric cancer,have high Hp infection rates,the relationships of Hp infections with some other diseases cannot be ignored and need to be further explored.
