ATVB:总的和白细胞亚群计数与心血管疾病和死亡率有关!

由此可见,在循环中的白细胞亚群中,男性中性粒细胞计数与致命和非致命性CVD之间的相关性一致。进一步研究降低循环中性粒细胞的干预措施,如canakinumab,有待调查因果关系。

白细胞计数升高与心血管疾病(CVD)风险增加有关。近日,心血管领域权威杂志Arteriosclerosis, Thrombosis, and Vascular Biology上发表了一篇研究文章,研究人员的目的是调查特定的白细胞亚群,这些亚群可能更密切地反映了特定的炎症途径,是否与CVD之间具有明确的相关性。

研究人员将白细胞计数数据可用来自于英国生物库的参与者(478259人)纳入研究。在中位随访时间7.0年(四分位间距为6.3-7.6)期间,统计了因CVD(n=1377)和非CVD原因(n=8987)而死亡。在Cox模型中,使用第五个十分位数作为参照组,研究人员评估了白细胞计数的十分位数(淋巴细胞、单核细胞、嗜中性粒细胞、嗜酸性粒细胞和嗜碱性粒细胞)。模型按性别进行分层,并针对一系列经典的危险因素进行调整。敏感性分析排除了基线合并症患者和前2年随访的参与者。

在中性粒细胞计数处于最高十分位数范围的男性(风险比[HR]为1.59,95%可信区间为1.22-2.08)和女性(HR为2.15; 95%可信区间为1.38-3.35)发生致命性CVD和非致命性CVD的风险最高(男性HR为1.28; 95%可信区间为1.16-1.42和女性HR为1.21; 95%可信区间为1.06-1.38)。在敏感性分析中,调查CVD死亡率的效能有限,但对于男性和女性合并后即可达到要求,白细胞计数和嗜中性粒细胞超过1×109/L的线性HR分别为1.05(1.03-1.07)和1.07(1.04-1.11)。

由此可见,在循环中的白细胞亚群中,男性中性粒细胞计数与致命和非致命性CVD之间的相关性一致。进一步研究降低循环中性粒细胞的干预措施,如canakinumab,有待调查因果关系。
