摘要 目的:探讨简化的Nijmegen法在诊断获得性凝血因子抑制物中的临床价值。方法:通过APTT测定、APTT交叉试验、APTT孵育交叉试验以及FVⅢ:C活性、FIX:C活性测定对可疑患者进行初步诊断;采用简化的Nijmegen法对4例初步诊断存在凝血因子抑制物的患者进行抑制物的定量测定。结果:4例患者APTT均延长;APTT交叉试验和APTT孵育交叉试验结果:加1/10正常血浆及等量正常血浆均不能使延长的APTT恢复正常,而且加入等量正常血浆的APTT随着孵育时间的延长而逐渐延长;4例患者中有1例为甲型血友病并发FVⅢ抑制物,其血浆FVⅢ:C活性及FVⅢ抑制物的测定结果分别为1.0%和320BU/mL;2例为获得性甲型血友病患者,其血浆FVⅢ:C分别为0.6%和1.3%,其血浆FVⅢ抑制物分别为92BU/mL和192BU/mL;另外1例为乙型血友病并发FIX抑制物,其血浆FIX:C活性及FIX抑制物的测定结果分别为1.2%和100BU/mL。结论:简化的Nijmegen法适合于对血友病患者或者获得性血友病患者产生凝血因子抑制物的分析评价;对凝血因子抑制物的检测有利于患者的诊断、治疗及预后判断。
