Abstract Detection had been made for the levels of serum specificity IgA, IgE antibodie and specificity of virus antigens circulation immune complexes (CIC) on the different days or phases of illness and clinic types in patients of HFRS. The results showed that the level of specific IgA antibody was higher in slight cases than in middle and severe; specific IgE antibody and its CIC was higher in severe cases than in slight and middle. Those differences were apparent in acute phase (illness phase of fever and shock-oilguria, or 3-8 days after illness). But specific CIC IgA types had no diferences.

对肾综合征出血热(HFRS)免疫发病机理研究较多的是IgG、IgM、IgE型抗体[1～4]。已有报告在HFRS患者血清中可检测到特异性IgA抗体[5～6]。为进一步了解HFRS患者发病过程中特异性抗体及其循环免疫复合物的形成及其致病性，我们平行测定了特异性IgA、IgE抗体以及抗原特异性IgA、IgE型循环免疫复合物(CIC)的水平，并从临床分型、病期、病日等角度作了对比分析。
1 材料与方法
1.1 HFRS病人血清 采集本市54例HFRS病人进出院时血清共108份。IgA型检测108份，IgE型检测其中93份。血清病期、病型分布见表1。
