Am J Resp Crit Care:重症血液病患者上呼吸道病毒检测的临床意义

2018-09-23 xing.T MedSci原创

由此可见,多重PCR检测上呼吸道呼吸道病毒常见于重症血液病患者。在ARF患者中,呼吸道病毒检测与ICU死亡率独立相关。多重PCR检测可能有助于血液病的ARF患者危险分层。有必要开展研究以了解呼吸道病毒是否在患者结局中发挥因果作用。

无创诊断性检查可确保早期识别和治疗血液系统恶性肿瘤患者的病毒感染。近日,呼吸内科以及重症医学领域权威杂志Am J Resp Crit Care上发表了一篇研究文章,该研究旨在评估重症血液病患者鼻拭子病毒PCR检测阳性的临床相关性。

研究人员对由17个ICU的危重病患者组成的前瞻性队列进行事后分析,并使用多重PCR测定法检测了在入住ICU时取样和冷冻的鼻拭子。研究人员确定了受试者的ICU死亡率和检测阳性的预测因子。

在747例患者中(447例急性呼吸衰竭[ARF]),21.3%的患者检测到病毒(56.4%的鼻病毒/肠道病毒和30.7%的流感/副流感病毒[PIV]/呼吸道合胞病毒[RSV])。整体ICU和住院死亡率分别为26%和37%。检查阳性与淋巴组织增生性疾病、造血干细胞移植、类固醇或其他免疫抑制剂治疗、ARF(25.5% vs. 16.3%,P=0.004)和ICU死亡(28.9% vs. 19.3%,P=0.008)有关。与ICU死亡率之间的关联对于所有病毒都是显著的,并且流感/PIV/RSV对于这种关联是最强的。在ARF患者中,任何呼吸道病毒的检测与ICU死亡率独立相关(比值比为2.07; 95%置信区间为1.22-3.50)。

由此可见,多重PCR检测上呼吸道呼吸道病毒常见于重症血液病患者。在ARF患者中,呼吸道病毒检测与ICU死亡率独立相关。多重PCR检测可能有助于血液病的ARF患者危险分层。有必要开展研究以了解呼吸道病毒是否在患者结局中发挥因果作用。
