摘要:

目的 探讨急性缺血性卒中(AIS)患者血清中细胞因子水平和免疫状态,阐明同型半胱氨酸(Hcy)水平、卒中后感染和吸烟等因素对AIS患者免疫反应的影响。 方法 选取AIS患者共53例,收集患者基础信息,并于发病72 h内收集患者血清样本,测定患者血清中各细胞因子水平,包括Hcy、白细胞介素 (IL)-2、IL-4、IL-6、IL-10、IL-17A、γ干扰素 (IFN-γ) 和肿瘤坏死因子α (TNF-α)。根据Hcy水平三分位数、卒中发生后并发感染和吸烟情况分别进行患者分组。比较各组患者基线资料和上述细胞因子水平的差异;采用多元线性回归模型分析AIS患者中各细胞因子水平与Hcy水平、吸烟情况及其他基线指标的相关性。 结果 与低水平Hcy组比较,高水平Hcy组患者血清中IL-6和IFN-γ水平明显升高(P<0.05)。多元线性回归分析,Hcy水平与IFN-γ水平间有关联(β=0.363,P<0.05)。与非感染组比较,感染组患者血清中IL-4水平明显升高(P<0.05);患者血清中IFN-γ/IL-4比值呈降低趋势,但差异无统计学意义(P>0.05)。与非吸烟组比较,吸烟组患者血清中IL-2、IL-6、IL-10和IFN-γ水平明显升高(P<0.05)。 结论 AIS患者中,高水平Hcy和吸烟与患者血清中多种促炎因子水平升高有关联,卒中后感染的发生与患者血清中抑炎性细胞因子的水平升高有关联。

Abstract:

Objective To discuss the levels of cytokines and the immune status in the serum of patients with acute ischemic stroke (AIS), and to clarify the effects of factors such as homocysteine (Hcy) level, post-stroke infection, and smoking on the immune response in AIS patients. Methods A total of 53 AIS patients were selected. Basic information of the patients was collected, and serum samples were collected within 72 h of onset. The levels of various cytokines in the serum of the patients were measured, including Hcy, interleukin (IL)-2, IL-4, IL-6, IL-10, IL-17A, interferon-γ (IFN-γ), and tumor necrosis factor-α (TNF-α). The patients were grouped according to the tertiles of Hcy level, the occurrence of post-stroke infection, and smoking status, respectively. The differences in baseline data and the levels of the above cytokines were compared among the patients in various groups; multiple linear regression models were used to analyze the correlations between the levels of various cytokines and Hcy level, smoking status, and other baseline indicators in AIS patients. Results Compared with low Hcy level group, the serum levels of IL-6 and IFN-γ in the patients in high Hcy level group were significantly increased (P<0.05). Multiple linear regression analysis showed an association between Hcy level and IFN-γ level (β=0.363, P<0.05). Compared with non-infection group, the serum level of IL-4 in the patients in infection group was significantly increased (P<0.05); the IFN-γ/IL-4 ratio in the serum of the patients showed a decreasing trend, but the difference was not statistically significant (P>0.05). Compared with non-smoking group, the serum levels of IL-2, IL-6, IL-10, and IFN-γ in the patients in smoking group were significantly increased (P<0.05). Conclusion In AIS patients, high Hcy level and smoking are associated with increased levels of multiple pro-inflammatory cytokines in the serum of the patients, and the occurrence of post-stroke infection is associated with increased levels of anti-inflammatory cytokines in the serum of the patients.
