| Abstract: |
| 目的 了解广州市非典型肺炎人群血清中严重急性呼吸综合征(SARS)冠状病毒(CoV)IgG抗体的基本特征及有关影响因素。方法 采集恢复期SARS、非SARS肺炎患者及SARS患者家庭密切接触者、野生动物、蔬菜销售者、社区对照人群的血清标本，用ELISA方法检测血清中SARS-CoV IgG抗体，并对SARS患者进行流行病学调查。结果 上述人群中，临床诊断为SARS患者SARS-CoV IgG抗体检出率最高，为53.7%，野生动物销售人员次之，为16.7%，社区普通人群为0.9%。在临床诊断的SARS患者中，可溯源病例抗体阳性率为90.4%，高于不可溯源病例的抗体阳性率为19.6%；且可溯源病例中低年龄组和高年龄组抗体阳性率低于中青年组，而不可溯源病例中不同年龄组患者抗体阳性率无差异；不同性别SARS患者的IgG抗体检出率也无差异；SARS抗体检出率呈逐月降低的趋势。结论 SARS临床诊断病例的血清SARS-CoV IgG抗体检出率只有53.7%，剔除患者年龄、使用激素、试剂盒等因素外，主要原因在于存在临床误诊的可能；实验室检测与流行病学调查相结合可明显提高SARS患者诊断的准确性；SARS-CoV存在隐性感染的可能，其在病毒传播过程中的作用有待进一步研究。 |

| Objective To probe blood serum Ab-IgG characteristics of severe acute respiratory syndrome(SARS)patients in Guangzhou and investigate the related factors. Methods The serum of such population diagnosed as SARS convalescent patients, non-SARS patients, family consanguineous contraction persons, wild animal and vegetable salesman and community common people was collected. The lab detective method of ELISA was adopted for these serum samples. And the epidemic investigations for the SARS patients were also carried out. Results Of these populations, the detective rate of Ab-IgG for the clinic diagnosed SARS patients, which was 53.7%; That for the wild animal salesman and community common people were 16.7% and 0.9%, respectively. Among the clinic diagnosed SARS patients, the positive antibody detective rate was 90.4% for those which had specific contact history or infectivity, which was higher than that for other population. Among the specific contacthistory or infectivity cases, the antibody positive rate for the young and the old was lower than that for the adult. Meanwhile the difference did not exist among other cases. The antibody positive rate was identical between the male and the female. And the antibody detective rate was decreased by the month. Conclusion As a whole SARS-CoV Ab-IgG detective rate for the clinic diagnosed SARS patients was 53.7% only. The reasons for that mainly lie in the wrong clinic diagnosis besides these factors such as age, hormone use and reagent and so on. The combination of lab detection results and epidemic investigation was propitious to the diagnosis veracity. It was impossible for the sub-clinic infection of SARS-CoV virus. The importance in the virus transmitting course need to be further studied. |
