Abstract： 目的探讨重度子(癎)前期患者血清中抗中性粒细胞胞浆抗体(antineutrophil cytoplasmic autoantibodies,ANCA)两种主要靶抗原蛋白酶3(protein3,PR3)和髓过氧化物酶(myeloperoxi-dase,MPO)的表达与子(癎)前期发病的关系. 方法用抗原特异性酶联免疫吸附法(ELISA)测定31例重度子(癎)前期和31例同期正常孕妇(对照组)血清中的PR3和MPO. 结果(1)重度子(癎)前期组PR3(+)者占25.8%(8/31),高于对照组的9.7%(3/31),但两组比较无统计学差异(x2=2.763,P＞0.05);重度子(癎)前期组MPO(+)占25.8%(8/31),对照组占19.4%(6/31),两组比较无统计学差异(x2=0.369,P＞0.05).(2)重度子(癎)前期组ANCA(+)者和ANCA(一)者比较各母儿并发症发生率无统计学差异,但肾功能不全患者共4例均发生于ANCA(+)者. 结论ANCA可能与子(癎)前期的肾脏病变有关,是否参与子(癎)前期的发病机制还有待于进一步研究.
