镰状细胞病(SCD)是血红蛋白(Hb)结构和合成的遗传性T障碍,包括纯合子镰状细胞贫血(Hb SS)、镰状细胞病(Hb SC)、Hb S和P地中海贫血的双杂合子组合(Hb S-thal)以及其他不太常见的变体。SCD的临床表现包括慢性溶血、频繁感染和各种其他急性和慢性并发症,这些并发症会导致器官损伤、残疾和死亡(表1和表2)。尽管目前的观点表明,变形不良的镰状红细胞(SS RBC)造成的微血管闭塞是SCD的关键病理生理事件,但微血管闭塞的机制和其他血管闭塞过程(如血管内膜增生、血栓形成和血管痉挛)的作用尚未完全确定。本综述旨在总结和批判性评价目前关于SCD血管闭塞的原因和后果的概念。尽管最近取得了实质性进展,但越来越明显的是,SCD中的血管闭塞是一个非常复杂的多因素过程,许多重要问题仍未得到解答。概述
HE SICKLE CELL diseases (SCD) are inherited T disorders of hemoglobin (Hb) structure and synthesis, and include homozygous sickle cell anemia (Hb SS), sickle-(= disease (Hb SC), double-heterozygous combinations of Hb S and P-thalassemia (Hb S-thal), and other less common variants. The clinical manifestations of SCD include chronic hemolysis, frequent infections, and a variety of other acute and chronic complications that produce organ damage, disability, and death (Tables 1 and 2). Although current thinking suggests that microvascular occlusion by poorly deformable sickle erythrocytes (SS RBC) is a key pathophysiologic event in SCD, the mechanism(s) of microvascular obstruction and the role of other vasocclusive processes such as vascular intimal hyperplasia, thrombosis, and vasospasm are not fully defined. This review seeks to summarize and critically evaluate current concepts regarding the cause(s) and consequences of vascular occlusion in SCD. Despite substantial recent progress, it is increasingly apparent that vascular occlusion in SCD is a very complex, multifactorial process, and that many important questions remain unanswered.
