不同透析方式尿毒症患者血清胱抑素C清除的研究(2)
叶智明等[10]对40例尿毒症患者血清胱抑素C的清除进行研究。40例尿毒症患者按透析方式不同分为血液透析滤过(HDF)组和血液透析(HD)组,每组20例,于治疗前、后分别测定血清胱抑素C水平。HD组治疗前(3.6±0.5)mg/L,治疗后(4.7±0.6)mg/L,透析后血清胱抑素C上升;HDF组治疗前(3.8±0.7)mg/L,治疗后(2.7±0.4)mg/L,透析后血清胱抑素C明显下降,两组治疗前后比较差异有统计学意义(P<0.01)。表明HDF能有效清除血清胱抑素C,HD则不能。
本研究采用高通量透析联合血液透析滤过(HD+HDF)对36位维持性血液透析患者进行为期6个月的治疗,结果表明:透后较透前血清胱抑素C和β2-微球蛋白均明显下降,随治疗时间的延长,下降更明显。每周1次HDF与每2周1次HDF的透前、透后血清胱抑素C和β2-微球蛋白浓度水平相似,说明短期内两种方式治疗效果相当。胱抑素C与β2-微球蛋白同属中分子毒素,不受炎症影响。胱抑素C下降率比β2-微球蛋白下降率略明显,透后下降40%~50%,胱抑素C较β2-微球蛋白性质稳定,且下降率更高,可用胱抑素C下降率作为中分子毒素清除效率的另一指标。

总之,普通透析清除血清胱抑素C作用有限,每次行HDF费用高,实施困难。联合应用(HD+HDF)清除血清胱抑素C是可行的,不仅降低了费用,且清除了中分子毒素,改善了尿毒症患者毒素蓄积,提高患者的生活质量。
