概括
像C反应蛋白 (CRP),乳酸盐 (Lac) 和互白素-1β (IL-1β) 这样的生物标志物有效地诊断儿科患者的晚发性败血症 (LOS). 促素 (PCT) 有助于区分细菌病因,指导向治疗.
科学领域:
- 儿童重症监护医疗
- 传染病诊断
- 生物标志物研究
背景情况:
- 晚发性败血症 (LOS) 在住院儿科患者中构成重大诊断挑战.
- 准确及时的差异诊断对于有效的治疗和改善患者的结果至关重要.
- 现有的诊断方法可能缺乏快速识别LOS所需的特异性和敏感性.
研究的目的:
- 评估各种炎症和代谢生物标志物的诊断潜力,以区分LOS与儿童患者的其他感染.
- 在一组经过测试的生物标志物中确定LOS的独立预测因素.
- 评估生物标志物的实用性,以区分Gram阳性和Gram阴性LOS的细菌原因.
主要方法:
- 从2022年1月到2023年12月的住院儿科患者的回顾性队列研究.
- 包括178名LOS患者和159名非LOS患者.
- 人口数据和生物标志物的水平分析,包括PCT,CRP,Lac,HBP,TNF-α,IL-6,IL-1β,IL-10和IL-12.
- 应用多变量逻辑回归和ROC曲线分析进行诊断评估.
主要成果:
- 在LOS和非LOS组之间观察到生物标志物水平 (PCT,CRP,Lac,HBP,TNF-α,IL-6,IL-1β,IL-10,IL-12) 的显著差异 (p < 0. 001).
- PCT,CRP,IL-6,IL-1β,IL-12和Lac被确定为LOS的独立预测剂.
- 一个结合CRP,Lac和IL-1β的模型显示出高的诊断性能 (AUC: 0. 958,敏感性:97. 8%,特异性:91. 8%).
- 在PCT中,Gram- 阴性与Gram- 阳性LOS的区分能力较小 (AUC: 0. 626).
结论:
- CRP,Lac和IL-1β的组合是一个强大的生物标记面板,用于诊断儿童重症监护室的LOS.
- 通过PCT,可以区分格拉姆阴性和格拉姆阳性细菌感染,从而实现向治疗.
- 这些发现支持使用这些生物标志物来改善儿科败血症的差异诊断和临床治疗.

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
213
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
