Helicobacter pylori ( Hp) is one of the most common infectious pathogens with a high infection rate and recurrence rate in humans worldwide.In developing countries , the prevalence of Hp infection can be up to 90%and its recurrence rate is also much higher than that in developed countries.The recurrence of Hp infection is either due to recrudescence or reinfection.Compared with reinfection , the time window for recrudescence is generally shorter.Recrudescence is generally considered as the recurrence of Hp infection within one year after eradication , followed by the recurrence of Hp-associated diseases shortly.This article reviews the factors related to Hp recrudescence.%幽门螺杆菌(Helicobacter pylori , Hp)是全球最常见的感染性病原菌之一,Hp感染有着较高的感染率及复发率.在发展中国家,Hp感染率可高达90%,且其年复发率也远高于发达国家.Hp复发可分为再燃和再感染,相比再感染而言,再燃的时间窗一般较短,一般认为Hp根治后1年内复发者称为再燃,随之而来的可能是短期内Hp相关疾病的复发.本文就Hp再燃影响因素的研究进展作一综述.
