概括
血公素 (pPCT) 没有有效地评估在败血症狗中抗菌治疗的疗效. 然而,较高的初始pPCT水平表明败血症患者的预后较差.
科学领域:
- 兽医医学 兽医医学 兽医医学
- 生物标志物 生物标志物
- 传染性疾病 传染性疾病
背景情况:
- 益生素 (PCT) 是人类细菌感染的关键生物标志物,指导抗菌疗法.
- C-反应蛋白 (CRP) 是狗的一般炎症标志物,缺乏细菌感染的特异性.
研究的目的:
- 在患有败血症,非传染性系统性炎症反应综合征 (nSIRS) 和健康对照的狗中研究血公素 (pPCT) 和C反应蛋白 (CRP) 动力学.
- 评估pPCT和CRP作为生物标志物的实用性,用于诊断细菌感染,并评估在狗中抗菌治疗的疗效.
主要方法:
- 这是一项前性观察性研究,涉及17只败血症狗,16只患有nSIRS的狗和15只健康的狗.
- 在3-4天内对血液学参数,pPCT和CRP进行连续测量.
- 血PCT量化使用验证的犬类PCTELISA.
主要成果:
- 在健康的狗,败血症的狗或患有NSIRS的狗之间没有观察到pPCT水平中位数的显著差异.
- 之前的抗微生物治疗没有改变败血症犬的pPCT度.
- 与败血症的幸存者相比,非幸存者中的第一天pPCT水平显著更高 (p <0.05).
- 在患有NSIRS和败血症的狗中,CRP水平的中位数升高,在成功的抗菌治疗后4天内下降.
结论:
- 血公素 (pPCT) 在犬类败血症中显示出预后价值,但不是评估抗菌治疗有效性的可靠指标.
- C-反应蛋白 (CRP) 显示出监测败血症狗的治疗反应的潜力.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
222
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...

Pericarditis II: Clinical Features and Diagnostic Tests
31
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...
