Stroke:脑出血后淋巴细胞减少症是不良预后的独立预测因子

2016-06-30 phylis 译 MedSci原创

背景:卒中相关的免疫抑制越来越成为公认的感染的触发因素,从而有可能影响卒中预后。具体来说,脑出血(ICH)后淋巴细胞减少只有在小型回顾性研究混合颅内出血中报道。该研究调查淋巴细胞减少的自然过程,入院和住院期间与淋巴细胞减少症(LOA)相关的参数,并且评估脑出血患者淋巴细胞减少对临床的影响。方法:这项观察性研究包括连续855例脑出血患者。机构前瞻性数据库中获取患者的人口统计学、临床和影像学资料以及实

背景:卒中相关的免疫抑制越来越成为公认的感染的触发因素,从而有可能影响卒中预后。具体来说,脑出血(ICH)后淋巴细胞减少只有在小型回顾性研究混合颅内出血中报道。该研究调查淋巴细胞减少的自然过程,入院和住院期间与淋巴细胞减少症(LOA)相关的参数,并且评估脑出血患者淋巴细胞减少对临床的影响。

方法:这项观察性研究包括连续855例脑出血患者。机构前瞻性数据库中获取患者的人口统计学、临床和影像学资料以及实验室和住院资料。通过邮寄问卷评估3个月的功能预后。淋巴细胞减少症被定义为小于1(109/L),并且与患者的特点及预后相关。

结果:LOA的患病率为27.3%。LOA的患者与不良神经功能状态(18 [ 10-32] vs 13 [5-24 ]),血肿量大(18.5 [6.21-46.2 ] vs 12.8 [4.4-37.8 ])、不良预后相关(74.7% vs 63.3%)。住院期间淋巴细胞计数的自然病程显示,第5天淋巴细胞为最低点1.1(0.80-1.53 [ 10(9)/升])。与LOA的患者相比,第5天淋巴细胞减少的患者感染发生率增加(63 [ 71.6 ] vs 113 [ 48.5 ]),3个月预后更差(76 [ 86.4 ] vs [ 75.1,175))。校正基线混杂因素,多变量Logistic和接受者操作特征的分析显示:第5天淋巴细胞减少与不良预后相关(第5天淋巴细胞减少:OR,2.017(95%CI,1.029-3.955);LOA:OR,1.391 [ 0.795-2.432 ];ROC:第5天淋巴细胞减少:ROC= 0.673,Youden指数= 0.290;LOA:ROC= 0.513,P = 0.676,约登指数= 0.084),而接受者操作特征分析显示年龄或血肿体积与第5天淋巴细胞减少症(年龄:ROC= 0.540,P = 0.198,约登指数= 0.106;血肿体积:ROC= 0.550, Youden指数= 0.1224)不相关。

结论:ICH患者常出现淋巴细胞减少症,可能与不良功能预后相关的独立因子。淋巴细胞减少症对预后的影响甚至比LOA更大,这一发现可能为特定亚型的ICH开辟新的治疗途径。

Stroke:脑出血后30天再入院的死亡率与感染相关

背景:脑出血后感染非常常见,但对出院后严重感染需要再入院的风险了解较少。方法:研究者进行了一项回顾性的队列研究,确定出院30天内,再入院患者中感染是否普遍存在。受试者为2006和2010间从加利福尼亚非联邦急性护理医院出院,初步诊断为脑出血的患者。研究者排除在入院期间死亡的患者,主动出院的患者及非加利福尼亚居民。研究的主要结果为30天内因原发性感染(国际疾病分类第九版,临床修改代码 ICM-9-C
