概括

与普通人群相比,患有骨髓纤维化 (MF) 的患者面临明显更高的重大出血和血栓事件的风险. 用JAK抑制剂治疗与MF患者的出血和凝固风险增加有关.

科学领域:

血液学血液学血液学
在瘤学瘤学.
流行病学流行病学

背景情况:

骨髓增殖性瘤 (MPNs) 与出血和血栓性并发症有关.
很少有研究专注于髓纤维化 (MF) 内的特定风险,这是MPNs的一个子集.

研究的目的:

评估MF患者严重出血,血栓事件和全因死亡率的频率.
为了将MF患者的这些事件率与匹配的对照进行比较.
分析MF不同治疗方式的事件率.

主要方法:

全国基于人口的研究,使用多个瑞典医疗保健登记册.
包括1079名被诊断为MF的患者和5395名匹配的对照.
分析主要出血,动脉事件,静脉事件和全因死亡率以及相关风险因素.

主要成果:

与对照组相比,MF患者的出血率 (HR 3.78),动脉事件 (HR 1.73),静脉事件 (HR 2.75) 和死亡率 (HR 3.92) 显著增加.
接受JAK抑制剂 (JAKis) 治疗的患者与没有治疗或氧尿素治疗的患者相比,出现较高的重大出血,动脉和静脉事件.
新发生血栓栓塞的独立风险因素包括JAKis,低分子量肝素,先前发生的事件和年龄较大. 主要出血风险与先前的静脉事件,高白细胞计数和正在进行的JAKi治疗有关.

结论:

骨髓纤维化患者的血栓栓塞事件和大出血率比其他MPN报告的更高.
血栓塞栓并发症和重大出血风险在不同治疗组之间存在差异,特别是在使用JAK抑制剂时.
对出血和血栓形成的风险分层对于管理多发性肺炎患者至关重要,考虑到治疗方式和患者特异性因素.

Disorders of Hemostasis

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
