[摘要] 幽门螺杆菌是一种具有传染性、感染率高的慢性致病菌,长期感染能够引起消化性溃疡、萎缩性胃炎和胃癌等多种疾病,还与人体多个系统疾病有关。临床治疗幽门螺杆菌的方法有多种,如传统三联疗法、经典四联疗法、序贯疗法和加用益生菌疗法等,但由于幽门螺杆菌对抗生素的耐药性,且使用抗生素副作用多,而益生菌有降低不良反应率,提升根除率的作用,在生活中和临床上越来越受到人们的重视。本文就益生菌在治疗幽门螺杆菌感染中的作用做一综述和展望,并对此疗法目前存在的问题进行讨论。

[Abstract] Helicobacter pylori is a type of chronic pathogen with infectivity and high infection rate. Long-term infection can cause peptic ulcer, atrophic gastritis, gastric cancer and other diseases, and it is also related with a number of systemic diseases of the human body. There are many ways to clinically treat Helicobacter pylori, such as classic triple therapy, classic quadruple therapy, sequential therapy and the addition of probiotics. However, because of the resistance of Helicobacter pylori to antibiotics, and the use of antibiotics have many side effects, probiotics have been raising greater attentions in daily life and in clinical practice due to its potential to reduce the rate of adverse reactions, and enhance eradication rate. In this paper, the review and outlook are made on the probiotics in the treatment of Helicobacter pylori infection, and the current problems of this therapy are discussed.

幽门螺杆菌(helicobacter pylori,Hp)主要通过鞭毛定植于胃黏膜,偶尔也定植于耳鼻喉、口腔、肠、胆囊等部位,是消化道疾病的诱因之一,可通过人与人之间传染。益生菌是一类对宿主有益的微生物,在人体内,它主要定植于肠道和生殖道内。近些年来,随着抗生素耐药率的提高和副作用增加,对Hp的根除率有所下降,基于此,中、西医领域对Hp感染的治疗方案也是层出不断,其中微生态制剂药品逐渐受到社会的青睐,常用的益生菌如乳酸杆菌、芽孢杆菌、双歧杆菌等菌种已成为治疗消化道疾病的良药。本文就Hp感染的治疗现状和益生菌对Hp感染的作用及其机制作一综述。

1.1 Hp的性状及作用机制
Hp是一种具有传染性的微需氧革兰阴性杆菌,电镜下可见4~7条鞭毛,有棒状、螺旋形和部分球形三种。……
