摘 要：目的：研究社区获得性肺炎(CAP) 与严重急性呼吸综合征(SARS)的不同特点。方法：比较2003年1月至2003年4月100例(广州市东山区)SARS患者和2001年1月至2003年1月100例CAP患者的临床症状、血象、放射学表现、转归等方面的特点，总结SARS的发病特点及病情发展规律。结果：①SARS患者出现38.5℃以上的发热、胸闷、头痛、肌痛症状的比例显著高于CAP患者(P<0.01)；②SARS患者白细胞降低的比例显著高于CAP患者(p<0.01)，白细胞升高的比例显著低于CAP患者(P<0.01)；③SARS患者病死率显著高于CAP患者(P<0.01) ④SARS患者抗体IgG显著高于CAP患者(P<0.01)。结论：SARS与CAP在临床症状、血象、胸片等方面都有不同特点，应注意区分，尽力作到早诊断、早隔离，避免SARS播散。

    Abstract: Objective: To study the features of community-acquired pneumonia (CAP) and severe acute respiratory syndrome (SARS). Method: The clinical presentation, chest radiographs, white blood cell count and outcome of 100 SARS patients from January to April 2003 were compared, with those of 100 CAP patients from January 2001 to January 2003 in our hospital, and the clinical features of SARS were summarized. Result: ①Fever above 38.5℃, short of breath, headache, myalgia in SARS were more common in SARS patients than those in CAP (P<0.01). ②Leucopenia was more common and leukocytosis was less common in SARS than those in CAP (P<0.01). ③The ratio of mortality in SARS was much higher than that in CAP (P<0.01).④SARS virus antibody IgG was much higher than that in CAP (P<0.01). Conclusion: The clinical presentation, chest radiographs, white blood cell count, and outcome in SARS are much different from CAP, differentiate them will be helpful to early recognition, prompt isolation, and prevention of its spread. ......
