炎症是对由创伤、缺血、感染和其他病理状况引起的细胞和组织损伤的生理反应。白细胞计数 (WBC) 升高和其他急性期反应物水平改变是炎症的主要迹象,但这些变化的动态及其解决方案尚未明确。在这里,我们通过跟踪住院患者临床实验室测量的纵向动态来研究创伤、缺血和感染的炎症恢复。我们确定了由指数白细胞衰减和血小板计数 (PLT) 延迟线性增长定义的通用恢复轨迹。 WBC-PLT 动态的共同调节是急性炎症恢复的基本机制,并为识别高危患者提供了通用方法:心脏手术不良结果的相对风险 (RR) 为 32 倍,COVID-19 死亡的相对风险为 9 倍,脓毒症死亡的 RR 为 9 倍,心肌梗死死亡的相对风险为 5 倍。炎症是身体的一种保护性反应。在这里,作者表明,无论潜在原因如何,包括心脏病发作、感染和创伤,健康的炎症都会引起白细胞和血小板群体的显着一致变化。
Inflammation is the physiologic reaction to cellular and tissue damage caused by trauma, ischemia, infection, and other pathologic conditions. Elevation of white blood cell count (WBC) and altered levels of other acute phase reactants are cardinal signs of inflammation, but the dynamics of these changes and their resolution are not well established. Here we studied inflammatory recovery from trauma, ischemia, and infection by tracking longitudinal dynamics of clinical laboratory measurements in hospitalized patients. We identified a universal recovery trajectory defined by exponential WBC decay and delayed linear growth of platelet count (PLT). Co-regulation of WBC-PLT dynamics is a fundamental mechanism of acute inflammatory recovery and provides a generic approach for identifying high-risk patients: 32x relative risk (RR) of adverse outcomes for cardiac surgery, 9x RR of death from COVID-19, 9x RR of death from sepsis, and 5x RR of death from myocardial infarction. Inflammation is a protective response of the body. Here, authors show that healthy inflammation induces remarkably consistent changes in white cell and platelet populations, regardless of the underlying cause, including heart attack, infection and trauma.
