作者在本文中探讨了血管炎的有关免疫学方面。机体的个体的免疫反应可决定血管炎的发生、类型、及/或范围。但目前对其机制了解尚少。除循环中的免疫复合物(其刺激抗原尚未弄清)外,有些血管炎出现肉芽肿提示细胞介导免疫机制也是重要的。在有些病人,免疫复合物或补体的系列测定可作为疾病活动性及疗效的评定的基础。以下分别就免疫复合物、补体、冷凝球蛋白、类风湿因子及细胞介导免疫等进行了阐明。 The author discusses the immunological aspects of vasculitis in this article. The individual’s immune response can determine the occurrence, type, and / or extent of vasculitis. However, little is known about its mechanism. In addition to circulating immune complexes that have not yet been elucidated to stimulate antigens, the appearance of granulomas in some vasculitis suggests that cell-mediated immune mechanisms are also important. In some patients, serial assays of immune complexes or complement may be used as a basis for evaluation of disease activity and efficacy. The following were immune complexes, complement, cryoglobulin, rheumatoid factor and cell-mediated immunity were clarified.
