2、例为文验组,于于术前隔日行DFPP(3~7次),加用免疫抑制剂。实验组患者每次DFPP前后抽取的血清及滤过弃物均采用流式细胞法测定PRA滴度变化。其余6例患者为对照组,移植前未作脱敏预处理。术后观察排斥反应发生情况及临床疗效。结果实验组早期第1例患者做了7次DFPP并加1其它免疫处理,前5次抗体滴度明显下降,但后两次处理后抗体出现反弹。其余4例患者经3~5次DFPP处理后,抗体滴度断下降。移植术后11例患者均末发生超急性排斥反应,实验组中有1例(1/5)发生细胞性排斥反膻,而无体液性排斥反应,对照组中有4例
3、(4/6)发生细胞性排斥反应,有3例(3/6)并发体液性排斥反应。结论I)FPP结合其它免疫处理方法进行脱敏预处理,能有效降低肾移卡fi术前PRA滴度,降低移值术后体液性排斥和细胞性排斥的发生风险。【关键词】双重滤过血浆置换;群体反应性抗体;流式细胞术;流式细胞术交叉配型;肾移植Influenceofdesensitizationpretreatmentonpanelreactiveantibodyandclinicaloutcomeinhighlysen-sitizedlivingrenaltranspl
