在创伤患者中,区分败血症与无菌炎症对于适当的治疗和患者的治疗结果至关重要.
败血症和无菌炎症的常见症状需要准确的诊断工具.
及时使用抗菌素治疗败血症的干预,以及在未感染创伤患者中明智地保留它们,至关重要.

研究的目的:

确定一个生物标志物小组,以区分早期的败血症与未感染创伤患者.
开发新的诊断方法,以区分创伤诱导的无菌炎症与传染性败血症.

主要方法:

采用了矩阵辅助激光溶解/电离 (MALDI) 和多重抗体阵列 (MAA).
在不同时间点对照,创伤和败血症休克患者组中的蛋白质模式进行了比较.
进行了丰富分析,以比较炎症反应.

主要成果:

确定SYT13和IL1F10作为潜在的早期败血症生物标志物.
在创伤炎症和败血症中观察到降低的α-2-宏球蛋白 (A2M) 水平.
在创伤患者的后期阶段注意到TREM1的升高以及明显的炎症通路激活 (补充,凝结与焦点粘附).

结论:

生物标志物的组合是必要的,以准确区分创伤诱导的无菌炎症和败血症.
研究结果表明,新的诊断策略有可能改善患者管理.

Inflammatory Response II: Inflammatory Exudate and Tissue Repair

Inflammatory Response II: Inflammatory Exudate and Tissue Repair

The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...
