【摘要】 幽门螺杆菌(Helicobacter pylori,Hp)是一种革兰阴性杆菌,被世界卫生组织国际癌症研究机构列为Ⅰ类致癌物,具有传染性。Hp感染后导致宿主胃和其他部位炎症的发生,且不同毒力型幽门螺杆菌感染引起的炎症反应程度不完全一致,反映在不同毒力型幽门螺杆菌感染后产生的各种炎症因子表达存在差异,其机制未完全清楚。本文就近年来国内外对不同Hp毒力因子感染及其引起的炎症因子,如白细胞介素-1β(IL-1β)、IL-2、IL-4、IL-6、IL-8、肿瘤坏死因子-α(TNF-α)、γ-干扰素(IFN-γ)的变化进行综述。

Research Status of the Relationship between Different Virulent Helicobacter Pylori Infection and Inflammatory Factors/LUO Chuntao, SUN Liming, CEN Chao. //Medical Innovation of China, 2024, 21(08): -169
[Abstract] Helicobacter pylori (Hp) is a kind of Gram-negative bacillus, listed as a groupⅠcarcinogen by the International Agency for Research on Cancer of the World Health Organization, and is contagious. Hp leads to the occurrence of gastric and other parts systemic inflammation of the host, and the degree of inflammatory reaction caused by different virulent Hp infection is not completely consistent, which is reflected in the different expression of various inflammatory factors produced by different virulent Hp, and its mechanism is not completely clear. In recent years, different Hp virulence factor infection and its induced inflammatory factors, such as interleukin-1β (IL-1β), IL-2, IL-4, IL-6, IL-8, tumor necrosis factor-α(TNF-α), gamma-interferon (IFN-γ) were reviewed at home and abroad.

幽門螺杆菌(Helicobacter pylori,Hp)是一种革兰阴性杆菌,是胃肠道及肠道外Hp感染相关疾病的致病因子[1],早在1994年,Hp被世界卫生组织国际癌症研究机构列为Ⅰ类致癌原,至2015年Hp感染相关性胃炎被认为是一种传染性疾病,在2022年新发布的《第六次全国幽门螺杆菌感染处理共识报告(非根除治疗部分)》中推荐如无根除制衡因素,所有的Hp感染者应该接受治疗,因为大多数Hp阳性个体虽然无症状,但感染易导致各种临床疾病的发展,如胃炎、消化性溃疡、胃癌和胃黏膜相关淋巴组织淋巴瘤等[2]。然而,这些并发症的发展是一个长期的过程,可能需要几十年的时间,并且是一个受胃环境、宿主基因、细菌毒力因子及炎症因子等多因素影响的过程[3]。近年来,国内外多项研究证实,Hp感染可通过不同的机制导致宿主炎症细胞因子发生不同的变化,从而使胃及其他部位发生炎症反应,这些因子包括白细胞介素类(ILS)、肿瘤坏死因子-α(TNF-α)、γ-干扰素(IFN-γ)等,且不同毒力型Hp感染引起的炎症因子变化程度不同,但其机制尚未完全清楚。……
