Clin Chem:儿童病毒或细菌感染I型干扰素的情况如何?

发热是3岁以下儿童急诊科就诊的主要原因之一。在发热病人中区分细菌和病毒感染的病因仍然具有困难。本研究提出针对病毒感染的特定宿主生物标记物,如i型干扰素(IFN),可有助于临床医生做出决定。

发热是3岁以下儿童急诊科就诊的主要原因之一。在发热病人中区分细菌和病毒感染的病因仍然具有困难。本研究提出针对病毒感染的特定宿主生物标记物,如i型干扰素(IFN),可有助于临床医生做出决定,并限制抗生素的过度使用。

研究人员采用Paxgene试管和血清采集自法国儿科急诊科正在治疗的发热儿童(n = 101)血液标本,这些患者年龄从7天到36个月,并被证实为病毒或细菌感染。研究人员评估了IFN的性能,基于使用Nanostring®技术对IFN刺激基因的表达进行量化,以及使用数字ELISA技术对血浆IFN-进行再量化。

研究结果显示经证实为病毒感染的2%(1/46)儿童和证实为细菌感染的71%(39/55)儿童的血清IFN-半胱氨酸含量低于定量阈值(30 fg/mL) (P < 0.001)。与细菌感染相比,病毒感染组的IFN-瘤病毒浓度和IFN评分显著高于细菌感染组(P < 0.001)。血清IFN- α浓度与IFN评分有显著相关性(p-pearson = 0.83)。与c反应蛋白(0.83)相比,发热患儿血清IFN-α血清浓度和IFN评分(曲线下面积>0.91)在病毒感染和细菌感染之间具有显著差异。

研究结果表明,有病毒感染的发热婴儿血液中IFN-α含量升高。IFN-α飞摩尔浓度的鉴别性能以及血液转录特征可能显示出诊断优势,并可能限制抗生素的过度使用。
