卒中相关性感染是卒中患者死亡的主要原因之一.最近的研究表明,卒中诱导的免疫抑制可使增高患者的感染易感性.卒中后免疫系统呈现双相变化.卒中后中枢神经系统驻留细胞(主要是小胶质细胞)被激活,产生促炎细胞因子和趋化因子,参与缺血性损伤；随后出现的系统性免疫抑制虽可增高患者感染易感性,但也促进神经发生.交感神经系统过度激活是免疫抑制发生的关键.

Stroke-associated infection is a leading cause of death in patients with stroke.Recent research indicated that stroke-induced immunodepression increases the susceptibility to infection.The immune system shows a biphasic change after stroke.Tne resident cells (mainly microglia) in the central nervous system are activated following stroke and produce pro-inflammatory cytokines and chemokines,which are involved in ischemic injury.Subsequent systemic immunodepression can result in increases susceptibility to infection,but it also facilitate neurogenesis.The ovcractivity of the sympathetic nervous system is the key to the development of immune suppression.The strategies for controlling stroke-associated infection include sympathetic antagonists,immunomodulators and prophylactic antibiotic therapy.
