幽门螺杆菌感染根治成功后复发的研究进展

Recurrence of Helicobacter pylori infection after successful eradication

幽门螺杆菌(Helicobacter pylori,H.pylori)是一种是革兰氏阴性、微需氧的细菌,生存于胃部及十二指肠内,感染后可以诱发消化性溃疡、胃癌等多种疾病,根治H.pylori可以预防多种相关疾病.然而成功根治后部分人会发生复发,人类发展指数(human development index)、家庭共同根治、联合口腔洁治及医源性传播等多种因素影响其复发.为此本文就H.pylori根治成功后复发作一综述.

Helicobacter pylori（H.pylori） is a gram-negative,micro-aerobic bacterium that lives in the stomachand duodenum.Infection with H.pylori would cause some diseases such as peptic ulcer disease and gastric cancer.Some H.pylori associated gastric diseases could be prevented by the eradication of H.pylori.However,some people develop recurrence after successful H.pylori eradication.Many factors affect the recurrence such as human development index,treatment for the whole family,standard treatment combined with supragingival scaling,and iatrogenic transmission.This article reviews the recurrence of H.pylori infection after successful treatment.
