多发性骨髓瘤117例血清免疫学特征分析

目的分析多发性骨髓瘤（MM）血清免疫学特征。方法对117例MM患者血清进行血清蛋白电泳、免疫固定电泳、免疫球蛋白（IgG、IgA、IgM）及总蛋白，白蛋白定量分析。结果117例MM患者血清蛋白电泳显示M带67例（57．3％），主要位于1区。免疫固定电泳分型：IgG型62例（53．0％），IgA型19例（16．3％），IgM型12例（10．1％），DL型2例（1．7％），轻链型22例（18．8％）。同型免疫球蛋白含量显著升高并常伴有非对应组分的偏低。血清总蛋白有不同程度的升高和白蛋白一定程度的降低。结论血清免疫学特征综合分析，对MM的诊断分型和临床分期及预后判断具有重要意义。

The seroimmunological analysis of 117 multiple myeloma cases in xinjiang

Objective To analyze the immunological feature of the multiple myeloma. Methods The serum of 117 cases were detected by serum protein electrophoresis and immunofixation electrophoresis;and analyzed quantitatively immune globulin(IgG、IgA、IgM) ,total protein and albumin. Results Monoclone protein peak was found in 67 patients out of 117 patients tested(57.3%) ,it located mainly at γ border. Immunoglobulin G was found in 62 patients out of 117 patients tested(53.0%). Immunoglobulin A was 19 cases(16.3%) ,Immunoglobulin M was 12 cases(10. 1%) ,DL was 2 cases(1.7%) ,free light chain was 22 cases(18.8%). Homotypic immunoglobulin level increased notably and non-correspond constituent was low in immunoglobulin test. The protein quantified displayed that total protein increased and albumin decreased in different level. Conclusion The seroimmunological index played a crucial role in diagnois,clinical stage and prognosis of MM.
