严重急性呼吸综合征 (SARS)是一种新型传染病 ,因其传染性强、病情重、死亡率高。SARS病毒感染后患者免疫系统过度激活并释放细胞因子等炎性介质 ,对肺泡造成弥漫性损伤 ,从而诱导产生急性呼吸窘迫综合征 ,同时引起的免疫损伤。本文就医学界关注的临床特点、病原学诊断、治疗中的抗病毒及激素应用、并发症和预后的研究进展进行综述。 Severe acute respiratory syndrome (SARS) is a new type of infectious disease, because of its high infectivity, serious illness and high mortality. SARS virus infection in patients with excessive activation of the immune system and the release of cytokines and other inflammatory mediators cause diffuse damage to the alveoli, resulting in the generation of acute respiratory distress syndrome, while causing immune damage. This article reviews the clinical features, medical diagnosis, pathogenic diagnosis, anti-virus and hormone application, complications and prognosis in medical field.
