概括
≥5 mg/dL的C-反应蛋白 (CRP) 水平显示出对儿童细菌感染的高特异性,支持经验性抗生素治疗. 然而,在各种CRP水平的低敏感性表明,当仅基于CRP的抗生素被保留时,应谨慎.
科学领域:
- 儿科急救医学 儿科急救医学
- 临床化学 临床化学
- 传染病诊断 传染病诊断 传染病诊断
背景情况:
- C-反应蛋白 (CRP) 是评估细菌感染概率的关键生物标志物.
- 儿科急诊室的经验性抗生素治疗决定通常依赖于CRP水平.
- 在这种情况下,了解CRP的诊断准确性至关重要.
研究的目的:
- 评估儿童急诊室患者的C反应蛋白 (CRP) 水平和细菌感染之间的关系.
- 确定各种CRP值的敏感性和特异性,用于诊断细菌感染.
主要方法:
- 对13,092例儿科急诊室病例进行了回顾性队列研究.
- 根据人口,临床和诊断参数计算CRP水平的相对风险 (RRs).
- 对2,5,7和10 mg/dL的CRP水平的敏感性和特异性的评估.
主要成果:
- 升高的CRP水平与发烧,白细胞瘤,住院和细菌感染诊断相关.
- 较低的CRP水平与年龄较小有关;没有发现与性别,种族,低血或中性恋有关.
- CRP ≥5 mg/dL对细菌疾病具有很高的特异性 (>80%),而在这个值下,敏感性下降 (<50%).
结论:
- CRP水平≥5 mg/dL为细菌感染提供高特异性,证明经验性抗生素启动是合理的.
- 在测试水平上CRP的低敏感性表明它可能不适合拒绝经验性抗生素治疗.
- CRP是一种有价值的工具,但应在儿科紧急情况中与临床背景一起解释.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
57
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...
