Investigation of Relationship Between Helicobacter Pylori Infection and Reflux Esophagitis / 中国医师杂志

ABSTRACT

Objective To investigate the relationship between helicobacter pylori (H. pylori) infection and reflux esophagitis (RE). Methods H.Pylori infection rates of RE in patients with simple chronic gastritis(CG),which was confirmed by gastrospcope combined with pathological diagnosis were researched.The relationship between HP infection and RE classifications using gastroscope and pathology was explored.Results ⑴H.pylori infection was found in 29(27.1%) in 107 cases of RE and 43(40.2%) in 107 cases of simple CG patients respectively,HP infection positive in RE patients less than that of simple CG patients.RE of class Ⅰ,Ⅱand Ⅲ using gastroscopy classification were 62.1%, 10.3% and 27.6% in H. Pylori-positive cases respectively, while they were 56.4%, 6.4% and 37.2% respectively in H. Pylori-negative ones. However, mild, moderate and severe RE identified by pathohistology were 72.4%, 13.8% and 13.8% in H.Pylori-positive cases respectively, and they were 57.7%, 17.9% and 24.4% respectively in H.Pylori-negative ones.Conclusions All above results suggested that H.Pylori possibly has prevention role in some extent to pathogenesis of RE. RE more commonly was seen in H.Pylori-negative cases.RE could inhibit the H.Pylori survive,So that,the RE was occurred frequently in H.Pylori-negative patients.The inflammatory extent of RE is not serious in H.Pylori-positive patients.
