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。
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.
