作者检查了45例皮肤变应性血管炎的IgG、IgA、IgM。病期大都自6个月到4～5年。浅部血管炎(24例)主要是变应性小动脉炎,皮损主要位于小腿,有时也可累及手,多形性,有红斑、出血性损害、结节、天疱疮样皮损,愈后留有瘢痕。深部血管炎(21例)主要为慢性结节性红斑。检查结果可见治疗前IgG、IgA含量增高而IgM则降低。免疫球蛋白含量的变化大部分与病情的严重度相符。治疗后趋向正常化。 30例(13例浅部,17例深部)作局部自身免疫溶
The authors examined 45 cases of skin allergic vasculitis IgG, IgA, IgM. Most of the disease period from 6 months to 4 to 5 years. Superficial vasculitis (24 cases) is mainly atopic arteritis, the lesion is mainly located in the lower leg, sometimes involving the hands, pleomorphism, erythema, hemorrhagic lesions, nodules, pemphigus-like lesions, The more scar left after. Deep vasculitis (21 cases) is mainly chronic nodular erythema. The test results showed that before treatment, IgG, IgA increased while IgM decreased. Most of the changes in immunoglobulin content are consistent with the severity of the disease. After treatment tends to normalize. 30 cases (13 cases of shallow, 17 cases of deep) for local autoimmune dissolution
