Cancers:胃癌高发地区幽门螺杆菌阴性和阳性胃炎中的胃菌群分析

2020-03-03 不详 网络

众所周知,幽门螺杆菌(H. pylori)相关的慢性胃炎是胃癌发展的主要病因。但是,对幽门螺杆菌阴性胃炎(HpN)的描述并不充分。本研究旨在检查与幽门螺杆菌阳性胃炎(HpP)和幽门螺杆菌阴性非胃炎组(对照组)相比,HpN的胃黏膜微生物群。研究纳入了11名HpN受试者,40名HpP受试者和24名对照。进行了六次胃活检的内镜检查。根据对疾病和幽门螺杆菌诊断的严格组织学标准定义了比较组。使用16S rR

众所周知,幽门螺杆菌(H. pylori)相关的慢性炎是癌发展的主要病因。但是,对幽门螺杆菌阴性胃炎(HpN)的描述并不充分。本研究旨在检查与幽门螺杆菌阳性胃炎(HpP)和幽门螺杆菌阴性非胃炎组(对照组)相比,HpN的胃黏膜微生物群。

研究纳入了11名HpN受试者,40名HpP受试者和24名对照。进行了六次胃活检的内镜检查。根据对疾病和幽门螺杆菌诊断的严格组织学标准定义了比较组。使用16S rRNA基因扩增子测序来根据比较人群对胃微生物群进行分析。

结果表明,与HpN或对照组相比,HpP组操作分类单位(OTU)计数以及Shannon和Simpson指数显示细菌丰度显著降低。线性判别分析效果量分析显示,HpN组中门菌水平的菌丝,梭菌,拟杆菌和放线菌含量较高。校正年龄后的多元分析中,链球菌sp.和副流感嗜血杆菌的HpN风险显著增加(分别为18.9和12.3)。根据发生情况,在HpN中仅发现梅毒螺旋体sp.。

总之,该研究结果表明,链球菌属,副流感嗜血杆菌和梅毒螺旋体属是HpN的候选致病细菌。如果证实这些结果可能具有重要的临床意义。
