重大创伤是年轻人死亡的主要原因。尽管院前系统和医院治疗取得了进步,但在过去的几十年里,死亡率并没有显著改善。严重受伤的受害者在最初的几个小时内存活下来,但有很大的风险出现其他危及生命的并发症,包括无法控制的感染(败血症)和多器官功能障碍综合征(MODS)。单核苷酸多态性(SNPs)已被证明影响许多疾病的易感性。越来越多的证据表明,遗传背景在创伤后并发症中也起着重要作用。遗传多态性可能成为创伤性并发症诊断和预后的有力生物标志物。最近关于遗传多态性与败血症或MODS之间关系的研究取得了进展,使人们对创伤后并发症有了更好的了解。在这里,我们总结了最近在先天免疫系统和其他系统分子的遗传变异以及它们与创伤后并发症易感性的联系方面的发现。
Major trauma is the leading cause of death in young adults. Despite advances in prehospital system and treatment in hospital, mortality rates have not improved significantly over the past decades. Victims of severe injuries who survive the initial hours have great risk for additional life-threatening complicaitons, including uncontrollable infection (sepsis) and multiple organ dysfunction syndrome (MODS). Single nucleotide polymorphisms (SNPs) have been shown to affect susceptibility to the course of numerous diseases. Accumulating evidence suggests that genetic backgrounds also play important roles in posttraumatic complications. Genetic polymorphisms may become powerful biomarkers for diagnosis and prognosis of trauma-induced complications. Recent advances in studies on associations between genetic polymorphisms and sepsis or MODS have led to better understanding of posttraumatic complications. Here we summarise recent findings on genetic variations in molecules of the innate immune system and other systems as well as their connection with susceptibility to posttraumatic complications.
