概括
血溶性ST2 (sST2) 水平独立预测急性呼吸衰竭 (ARF) 的死亡率. 升高的sST2与器官功能障碍有关,这表明IL-33/ST2轴是ARF的治疗点.
科学领域:
- 在重症监护医学的生物标志物.
- 急性呼吸衰竭的免疫学
- 介素-33 (IL-33) 信号通路的信号通路.
背景情况:
- 可溶性ST2 (sST2) 是IL-33的诱受体,这是一个关键的警报.
- sST2与急性呼吸衰竭 (ARF) 的不良结果有关.
- 了解ARF中的sST2分布和关联对于临床管理至关重要.
研究的目的:
- 评估不同ARF患者队列中的sST2分布.
- 为了比较血和下呼吸道 (LRT) 的sST2度.
- 检查sST2与器官功能障碍的关联,亚表型和ARF的结果.
主要方法:
- 使用ARF患者的多中心队列的观察性研究.
- 包括1432名ARF患者 (863名非COVID患者,569名COVID-19患者).
- 在血和LRT标本中测量sST2,并对关联进行统计分析.
主要成果:
- 非COVID ARF患者的血sST2水平高于COVID-19患者,并且与LRT水平相比明显升高.
- 血sST2升高与肺外器官功能障碍和高炎症ARF亚表型相关.
- 血sST2独立预测了ARF患者的30天死亡率,而非幸存者的持续较高水平.
结论:
- 血sST2是ARF结果的独立预测器,与肺外器官功能障碍密切相关.
- 血和LRT sST2之间的弱相关性表明主要是系统性起源.
- IL-33/ST2轴代表了ARF和多器官功能障碍的潜在治疗标.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
40
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...

Acute Respiratory Failure-II
158
Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

Acute Respiratory Failure-V
113
The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
