目前,有资料认为体液免疫障碍在类风湿性关节炎(RA)的免疫病理机制中只起次要作用,细胞免疫失衡更具重要性。也有否定细胞反应在 RA 发病机制中可能意义的报道。为探讨 RA 的体液免疫水平,我们测定了25例 RA 患者的血清循环免疫复合物(CIC)、IgG,IgA、IgM 和 C_3、C_4、B因子含量,结果报告如下。 Currently, there is data that humoral immune disorder only plays a secondary role in the immune pathology of rheumatoid arthritis (RA), cellular imbalance is more important. There are also reports that negative cellular responses may have implications in the pathogenesis of RA. To investigate the humoral immunity of RA, we measured serum circulating immune complex (CIC), IgG, IgA, IgM and C_3, C_4 and B factors in 25 RA patients and the results are reported as follows.
