本文报告21例自身免疫性溶血性贫血。其中原发性12例,继发性9例,全部经抗人球蛋白试验证实。并首先分出5例IgG型。原发与继发性临床上有时鉴别困难。从“比较免疫学”观点认为:人类的自身免疫过程与NZB鼠类似,应早诊早治,免使病程迁延。导致多数器官受损。 This article reports 21 cases of autoimmune hemolytic anemia. Of which 12 cases of primary, secondary in 9 cases, all confirmed by anti-human globulin test. And first of all 5 cases of IgG type. Primary and secondary clinical sometimes difficult to identify. From the “comparative immunology” point of view that: the process of human autoimmunity and NZB mice similar, early diagnosis and treatment should be early, so as not to delay the course of the disease. Causes damage to most organs.
