系统性红斑狼疮(SLE),是一种侵犯多种脏器的疾病,病因至今不明。目前多数人认为,该病是一种自身免疫性疾病。通常出现T细胞功能下降,B细胞功能亢进,血清中可检出多种自身抗体和免疫复合物,补体水平于疾病进展期低下。本文为进一步探讨体液免疫功能变化及其临床意义,自1980-1982年对住院的SLE病人,作了免疫球蛋白(IgG,IgA,IgM),总补体,补体C_3。及循环免疫复合物,抗DNA结合率的测定,现将检测结果报告如下: Systemic lupus erythematosus (SLE), is a disease that invades a variety of organs, the etiology is still unknown. At present, most people think that the disease is an autoimmune disease. Usually appear T-cell function decline, B cell hyperthyroidism, the serum can be detected in a variety of autoantibodies and immune complexes, complement levels in disease progression is low. In order to further explore the changes of humoral immune function and its clinical significance, immunoglobulins (IgG, IgA, IgM), total complement and complement C_3 were made for hospitalized SLE patients from 1980 to 1982. And circulating immune complexes, anti-DNA binding rate determination, the test results are reported as follows:
