摘  要:目的:探讨幽门螺杆菌(HP)及细胞毒素相关蛋白毒力型HP(HP—CagA)感染对冠心病患者血清炎性因子及同型半胱氨酸(Hey冰平影响以及HP—CagA感染与冠心病的相关性。方法:应用酶联免疫吸附分析法测定105例冠心病患者(冠心病组)和76例同期住院非冠心病患者(对照组)的血清HP特异性IgG抗体及其CagA特异性IgG抗体;采用乳胶增强散射免疫比浊法测定血清高敏C反应蛋白(hs—CRP);采用化学发光法测定血清中肿瘤坏死因子-α(TNF-Ⅱ)、白细胞介素一6(IL一6)和Hcy水平,并比较HP感染的冠心病患者与非HP感染患者之间的差异,以及HP—CagA—IgG阳性患者与HP—CagA—IgG阴性患者之间的差异。应用多元Logistic回归分析危险因素对冠心病的影响,用调整后的比值比(OR)和95%可信区间(CI)评估HP抗体阳性对患冠心病的危险性。结果:冠心病组与对照组HP—IgG抗体的阳性率分别为52.3%和35.5%,差异有统计学意义(P〈0.05);冠心病组血清hs—CRP、TNF—α、IL一6和Hcy水平高于对照组,差异有统计学意义(P〈O.05);冠心病组HP—IgG阳性患者中,HP—CagA—IgG阳性患者hs—CRP、TNF一仅、IL一6和Hcy血清浓度水平高于HP—CagA—IgG阴性患者(P均〈O.05)。应用Logistic多元回归分析,在排除其他传统因素后,HP—IgG阳性和HP—CagA—IgG阳性对患冠心病存在相对危险性(OR=2.278,3.297;95%CI:1.20~4.32,1.50~7.27;P=0.012,0.003)。结论:冠心病的发生可能与HP感染有关系,HP—CagA感染可能通过刺激机体产生更多的炎性因子和Hcy,加快冠心病的发生、发展,是冠心病的危险因素之一。Objective: To study the relationship between helicobacter pylori (HP) infection and inflammatory cytokines, homocysteine (Hcy) in patients with coronary artery disease (CAD), and the relationship between cytotoxin associated protein A toxins of liP (HPCagA) and CAD occurrence. Methods: Our research included 2 groups: CAD group, n=105 and Control group, n=76 patients without CAD. The serum Hp-IgG antibody and HpCagA-IgG antibody were measured by ELISA. Blood levels of Hs-CRP, TNF-α, IL-6 and Hcy were examined and compared between 2 groups. The differences between CAD patients with HP infection and without HP infection were compared, and the differences between CAD patients with positive HPCagA-IgG and negative HPCagA-IgG were compared Logistic regression analysis was conducted to study the risk factors of CAD, the adjusted OR and 95% CI were used to evaluate the positive Hp for CAD risk. Results: The positive rate of HP-IgG in CAD group and Control group were 52.3% and 35.5%; compared with Control group, CAD group had the increased levels of Hs-CRP, TNF-α, IL-6 and Hcy; in CAD group, the patients with positive HP-IgG showed the higher levels of Hs-CRP, TNF-α, IL-6 and Hcy than those with negative HP-IgG, and the patients with positive HpCagA-IgG presented the higher levels of Hs-CRP, TNF-α, IL-6 and Hcy than those with negative HPCagA-IgG, all P〈0.05. Logistic regression analysis indicated that with adjusted traditional risk factors, the positive HP-IgG and positive HpCagA-IgG were the risk factors for CAD (OR=2.278, 95% CI 1.20-4.32, P=0.012 and OR=3.297, 95% CI 1.50-7.27, P=0.003). Conclusion: HP infection might be related to CAD, and the patients with HP infection and positive HPCagA-IgG could have CAD occurrence and development.
