Crit Care Med:脓毒症与微血管脑损伤的关系

2019-08-12 xing.T MedSci原创

由此可见,通过微血管梗塞评估,脓毒症与中度至重度血管脑损伤特异性相关。对于大脑皮质内的微小梗塞,这种关联更强,那些经历严重脓毒症住院治疗的患者在调整分析中有中度至重度大脑皮质损伤证据的可能性超过两倍。需要进一步研究以确定脓毒症和微小梗塞之间的相关机制。

许多败血症的幸存者会出现长期认知障碍,但这种关联的机制仍然未知。近日,危重病医学领域权威杂志Critical Care Medicine上发表了一篇研究文章,这项研究的目的是确定脓毒症是否与脑微小梗塞相关。

该研究为包含529名参与者的回顾性队列研究,这些参与者住居于华盛顿,大于或等于65岁,且在研究开始时无痴呆症并且死后接受过大脑尸检。研究人员使用行政数据确定晚期脓毒症住院治疗情况,在研究期间确定了89名至少住院1次的脓毒症患者,其中80名患者在住院后存活,出院后死亡时间的中位数为169天。

30%至少住院1次的脓毒症患者有超过2处微小梗塞,相比于没有住院的脓毒症的患者,其为19%(χ2p=0.02); 脓毒症住院患者中有20%的患者大脑皮层中有超过2处微小梗塞,而相比于没有住院的脓毒症的患者,其为10%(χ2p=0.01)。超过2处微小梗塞调整后的相对风险为1.61(95%CI为1.01-2.57; p=0.04); 在大脑皮质中具有超过2处微小梗塞的相对风险是2.12(95%CI为1.12-4.02; p=0.02)。路易体在脓毒症患者中较少见。

由此可见,通过微血管梗塞评估,脓毒症与中度至重度血管脑损伤特异性相关。对于大脑皮质内的微小梗塞,这种关联更强,那些经历严重脓毒症住院治疗的患者在调整分析中有中度至重度大脑皮质损伤证据的可能性超过两倍。需要进一步研究以确定脓毒症和微小梗塞之间的相关机制。
