概括
与输血相关的循环过载 (TACO) 可能涉及炎症,而不仅仅是液体过载. 在TACO患者中发现IL-6和IL-8细胞因子升高,这表明炎症途径有助于这种输血并发症.
科学领域:
- 输血医学
- 免疫学
- 危急护理医学
背景情况:
- 输血相关的循环过载 (TACO) 是输血相关死亡的主要原因.
- 历史上归因于水静力,最近的证据表明炎症过程也可能起作用.
- 了解TACO的病理生理学对于改善患者的结果至关重要.
研究的目的:
- 调查TACO患者的炎症存在和程度.
- 在传统的TACO (cTACO) 和机构的TACO (iTACO) 病例中区分炎症特征.
- 探索TACO与输血相关的急性肺损伤 (TRALI) 之间的潜在重叠.
主要方法:
- 对三个红细胞输血队列的回顾性研究:cTACO (n=33),iTACO (n=33) 和无并发症输血 (n=6).
- 血清炎症标志物 (细胞因子,粘附分子,生物标志物) 输血前后的分析.
- 包括生命体征和体温在内的临床数据被收集并与不同组进行比较.
主要成果:
- 患有cTACO和iTACO的患者在输血后出现发烧,心率下降和氧和.
- 在cTACO和iTACO组中观察到高水平的促炎细胞因子IL- 6和IL- 8.
- 细胞间粘附分子1 (ICAM-1) 在输血后增加,特别是在iTACO组中.
结论:
- 炎症途径似乎参与了TACO的发展.
- iTACO患者的明显炎症特征表明TACO和TRALI之间存在潜在的重叠或中间状态.
- 需要进一步的研究来阐明炎症在TACO病变中的作用.

12.4K
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

01:20Extrinsic and Intrinsic Pathways of Hemostasis
9.2K
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...
