J Cereb Blood Flow Metab:卒中相关免疫抑制和吞咽困难可预测卒中相关肺炎

2016-10-20 MedSci MedSci原创

卒中相关性肺炎是脑卒中后常见的并发症,严重影响预后。吞咽困难是卒中相关肺炎的危险因素,但越来越多的证据表明,脑卒中诱导免疫抑制增加卒中相关性肺炎的易感性。本研究旨在确定卒中所致免疫抑制综合征独立于吞咽困难,与卒中相关肺炎独立相关,本研究调查单核细胞HLA-DR表达作为免疫抑制的标志物及炎症标志物IL-6及感染的发生(细菌脂多糖结合蛋白)。这是一项前瞻性、多中心的研究,包括德国和西班牙在内的11个研

卒中相关性肺炎是脑卒中后常见的并发症,严重影响预后。吞咽困难是卒中相关肺炎的危险因素,但越来越多的证据表明,脑卒中诱导免疫抑制增加卒中相关性肺炎的易感性。本研究旨在确定卒中所致免疫抑制综合征独立于吞咽困难,与卒中相关肺炎独立相关,本研究调查单核细胞HLA-DR表达作为免疫抑制的标志物及炎症标志物IL-6及感染的发生(细菌脂多糖结合蛋白)。

这是一项前瞻性、多中心的研究,包括德国和西班牙在内的11个研究地点,其中包括486例急性缺血性卒中。每日筛查卒中相关性肺炎、吞咽困难的发生及生物标志物。脑卒中相关性肺炎的发生率为5.2%。多变量回归分析显示吞咽困难和单核细胞HLA-DR降低为卒中相关性肺炎的独立危险因素。单核细胞HLA-DR的最高四分位数(≥21876 mAb/细胞)与最低四分位数(≤12369 mAb /细胞)患者,肺炎的发生率范围从0.9%到8.5%。在存在吞咽困难的患者中,肺炎发生的比例分别增加到5.9%和18.8%。无吞咽困难和单核细胞HLA-DR正常的患者,无卒中相关性肺炎的风险。

研究表明,吞咽困难和脑卒中诱导的免疫抑制是卒中相关性肺炎的独立危险因素。对免疫抑制和吞咽困难筛查可能有助于识别卒中相关性肺炎高风险患者。
