柴胡桂枝汤对反复呼吸道感染患儿免疫球蛋白及IgG亚类的影响

目的：观察柴胡桂枝汤对反复呼吸道感染（ＲＲＴＩ）患儿免疫球蛋白（Ｉｇ）及ＩｇＧ亚类的影响。方法：采用免疫扩散法和酶联免疫吸附法，检测了２３例ＲＲＴＩ患儿柴胡桂枝汤治疗前后Ｉｇ和ＩｇＧ亚美的含量，并与正常对照组比较。结果：ＲＲＴＩ患儿ＩｇＧ、ＩｇＡ、ＩｇＭ浓度均显著低于正常对照组（Ｐ＜０．０１），ＩｇＧ亚美缺陷率６０．９％。柴胡桂枝汤治疗临床总有效率９５．６％，血清ＩｇＧ浓度较治疗前明显升高（Ｐ＜０．０５），ＩｇＧ亚类缺陷纠正率７１．４％。结论：免疫功能降低，ＩｇＧ亚美缺陷是ＲＲＴＩ发病的重要因素。改善免疫功能，纠正ＩｇＧ亚美缺陷状态可能是柴胡桂枝汤治疗ＲＲＴＩ的机理之一。

英文摘要:

To observe the effect of Chaihu Guizhi Decoction (CGD) on Immunoglobulin (Ig) and IgG subgroup in children with recurrent respiratory tract infection (RRTI). Methods: Levels of ig and IgG subgroup were measured in 23 cases of children with RRTI before and after treating with CGD, and compared with those in the control group. Results: In RRTI group, the levels of IgG, IgA, IgM and IgG1 were lower than those of the control groups respectively (P<0.01 ). The rate of IgG subgroup deficiency (ISD) was 60.9%. The effective rate of the CGD group was 95.6%. The IgG and IgG1 levels were increased after treatment as compared with before treatment (P<0.05), and the ISD correcting rate being 71.4%. Conclusions: The hypoimmunofunction and IgG subgroup deficiency were important factors in RRTI pathogenesis. The CGD could improve the immunofunction and correct the IgG subguoup deficiency, and this effect might be one of the mechanism of CGD in treating RRTI.
