Some studies have indicated a protective role of H.pylori against risk of esophageal squamous cell carcinoma (ESCC). The purpose of this study was to explore this possible relationship in a case-control study.
One hundred consecutive patients diagnosed with ESCC and 100 healthy people were entered with informed consent. All were asked to provide a blood sample and serum immunoglobulin G (IgG) antibodies against HP-CSAs were measured with an enzyme-linked immunosorbent assay (ELISA).
There was significant reverse association between H. pylori positivity and tumour development (OR=0.28, 95% CI: 0.15-0.54), but not with a Cag A positive status.
Our findings provide further evidence that H. pylori infection decreases the risk of ESCC but that this is not linked to a Cag A positive status.
一些研究表明幽门螺杆菌对食管鳞状细胞癌(ESCC)风险具有保护作用。本研究的目的是在一项病例对照研究中探讨这种可能的关系。
100例连续诊断为ESCC的患者和100名健康人在获得知情同意后纳入研究。所有受试者均被要求提供血样,并采用酶联免疫吸附测定(ELISA)检测血清抗幽门螺杆菌细胞毒素相关蛋白A(HP-CSAs)免疫球蛋白G(IgG)抗体。
幽门螺杆菌阳性与肿瘤发生之间存在显著的负相关(OR=0.28,95%可信区间:0.15-0.54),但与细胞毒素相关基因A(Cag A)阳性状态无关。
我们的研究结果进一步证明,幽门螺杆菌感染可降低ESCC风险,但这与Cag A阳性状态无关。
