急性呼吸道感染 (ARI) 是寻求医疗救助的常见原因,大流行性流感的威胁可能会增加这些数字。通过对活鼻病毒、呼吸道合胞病毒和甲型流感病毒进行人类病毒攻击研究,我们开发了外周血基因表达特征,能够以 > 95% 的准确度区分有症状的 ARI 个体和未感染个体。我们在每次病毒挑战中验证了这种“急性呼吸道病毒”特征——包含在宿主防御病毒感染中具有已知作用的基因。我们还在独立获取的甲型流感数据集中验证了特征,并以 100% 的准确度将感染者与健康对照者进行了分类。在同一数据集中,我们还可以区分病毒 ARI 和细菌 ARI(准确率 93%)。这些结果表明,ARIs 会引起人外周血基因表达的变化,可用于诊断呼吸道感染的病毒病因并对有症状的个体进行分类。
Acute respiratory infections (ARI) are a common reason for seeking medical attention and the threat of pandemic influenza will likely add to these numbers. Using human viral challenge studies with live rhinovirus, respiratory syncytial virus, and influenza A, we developed peripheral blood gene expression signatures that distinguish individuals with symptomatic ARI from uninfected individuals with > 95% accuracy. We validated this “acute respiratory viral” signature - encompassing genes with a known role in host defense against viral infections - across each viral challenge. We also validated the signature in an independently acquired dataset for influenza A and classified infected individuals from healthy controls with 100% accuracy. In the same dataset, we could also distinguish viral from bacterial ARIs (93% accuracy). These results demonstrate that ARIs induce changes in human peripheral blood gene expression that can be used to diagnose a viral etiology of respiratory infection and triage symptomatic individuals.
