Inflammation may play an important role in acute ischemic stroke. Experimental and clinical data suggest that post-stroke inflammatory responses are complex cascade phenomena, which may have detrimental or beneficial effects on outcome. This review focuses on the current understanding of inflammation effector pathways in focal cerebral ischemia and on therapeutic perspectives.
STATE OF ARTS/PERSPECTIVES: Somatic markers, such as admission body temperature or C-reactive protein, seem to be correlated with outcome, but data are heterogeous and contradictory, perhaps because their kinetics are complex during the first hours of a stroke. The most studied effectors of inflammation are cellular adhesion molecules--CAM (including integrins, selectins and members of the immunoglobulin superfamily), leucocytes, microglia, and blood brain barrier permeability. Evidence from animal data has lead to some clinical trials investigating anti adhesion molecules and hypothermia. However, current results remain disappointing. Recent experimental data also suggest a possible beneficial role of insulin and statins, which may be mediated by their effects on the inflammatory response.
Inflammation is an important avenue of therapeutic research in acute stroke. A better understanding of the inflammatory pathophysiology may help to a better design of clinical trials.
炎症可能在急性缺血性卒中中发挥重要作用。实验和临床数据表明,卒中后的炎症反应是复杂的级联现象,可能对预后产生有害或有益的影响。本综述聚焦于目前对局灶性脑缺血中炎症效应途径的理解以及治疗前景。
现状/展望:一些躯体标志物,如入院时体温或C反应蛋白,似乎与预后相关,但数据存在异质性且相互矛盾,这可能是因为它们在卒中最初几小时内的变化动态较为复杂。研究最多的炎症效应因子包括细胞黏附分子——CAM(包括整合素、选择素和免疫球蛋白超家族成员)、白细胞、小胶质细胞以及血脑屏障通透性。动物实验数据促使了一些关于抗黏附分子和低温治疗的临床试验。然而,目前的结果仍然令人失望。近期的实验数据还表明胰岛素和他汀类药物可能具有有益作用,这可能是通过它们对炎症反应的影响介导的。
炎症是急性卒中治疗研究的重要途径。更好地理解炎症病理生理学可能有助于更好地设计临床试验。
