严重急性呼吸综合征的细胞免疫功能研究

目的　探讨严重急性呼吸综合征 (SARS)患者细胞免疫功能的动态变化及探讨免疫功能与病情进展的关系。方法　选择急性SARS患者 10 7例 ,按照疾病预后分成死亡组和治愈组 ,回顾性分析免疫功能的动态变化及免疫功能在两组间的差异。结果　SARS患者免疫功能在极期下降到最低点 ,呈现一过性免疫缺陷 ,此后迅速恢复。死亡组与治愈组比较 :疾病初期和进展期的细胞免疫功能差异无显著性 (P >0 .0 5) ,两组的CD3 +、CD4+、CD8+在病初和进展期分别为 63 9.14± 2 87.0 8/62 8.63± 3 16.85,2 95.57± 191.0 1/ 3 3 3 .3 3± 188.64,3 0 0 .71± 10 6.76/ 2 51.85± 12 5.92 ,63 5.0 0±449.50 / 790 .0 3± 558.3 0 ,3 72 .0 0± 3 0 3 .3 7/ 4 17.0 9± 3 12 .0 4,2 52 .71± 14 7.44/ 3 3 8.43± 3 0 0 .3 6;极期和恢复期的细胞免疫功能差异非常显著 (P <0 .0 1) ,死亡组和治愈组在极期与恢复期的CD3 +、CD4+、CD8+分别为 3 0 4.0 0± 84.2 6/ 70 1.97± 489.43 ,171.11± 78.84/ 3 99.41± 3 3 2 .40 ,13 3 .2 2±2 4.3 1/ 2 87.71± 199.88,3 4 9.50± 183 .84/ 112 0 .2 9± 565.42 ,2 0 2 .0 0± 10 1.89/ 645.12± 3 76.3 3 ,13 9.79± 87.0 7/ 4 53 .0 9± 2 51.0 6。结论　SARS确实影响机体免疫功能 ,大

Study of immunological function in severe acute respiratory syndrome

Objective To discuss the relationship between disease progress with the change of cell im munological function as well as the effect of immunological function in severe a cute respiratory syndrome. Methods Retrospective study was designed to analyze the relationship of disease progres s with the change of immunological function. According to the disease outcomes, the patients are divided into two groups: died group and survival group. The dif feren ce of immunological function in groups was performed statistics analysis. Results Immunological function (CD3 +, CD4 +, CD8 +) descended to the lowest level in period of fastigium in SARS patient, and then recovery quickly. Comparison of died grou p and survival group was found that Immunological function (CD3 +T, CD4 +T, CD 8 +T) were lower in period of fastigium and recovery in died group than in survival g roup(P <0.001 ). Conclusion Immunological function was affected by SARS infec tion, but transiently in most cases. Only a minor of dead cases displayed irreve rsible inhibition of immune function.
