不同血液净化方法对慢性肾衰竭维持性血液透析患者血清β2-微球蛋白的影响

目的 探讨不同血液净化方法对慢性肾衰竭维持性血液透析(MHD)患者血清β2-微球蛋白(β2-MG)的清除效果.方法 将40例慢性肾衰竭MHD患者随机分为四组:血液透析(HD)组,高通量血液透析(HFD)组,血液透析滤过(HDF)组,HD+血液吸附(AP)组,每组各10例.记录患者治疗前后血清β2-MG测得值并进行组内和组间统计学比较.结果 HD组第1次血液净化后β2-MG测得值[(53.49±1.15)mg/L]较第1次血液净化前(基线值)[(49.10±2.31)ms/L]上升但差异无统计学意义(P>0.05),6个月血液净化后β2-MG测得值[(55.63±1.30)mg/L]较基线值上升且差异有统计学意义(P<0.05).HFD组、HDF组和HD+AP组第1次血液净化后及6个月血液净化后β2-MG测得值较基线值均有明显下降趋势(P<0.05).并且HD+AP组6个月血液净化后β2-MG测得值较HFD组和HDF组下降趋势更为明显(P<0.05).结论 HD对β2-MG无清除效果,HFD、HDF和HD+AP能有效清除β2-MG,并且6个月后HD+AP清除β2-MG效果更佳.

Clinical investigation of different blood purification techniques on clearing serum beta2-microglobnlin of chronic renal failure maintenance hemodialysis patients

Objective To investigate the clear effect of different blood purification techniques on the serum beta2-microglobulin ( β2-MG) of chronic renal failure maintenance hemodialysis patients.Methods Forty chronic renal failure maintenance hemedialysis patients were randomly divided into four groups: hemodialysis group (HD group), high flux dialysis group (HFD group), hemodiafiltration group (H D F group), hemodialysis and absorption group (HD+AP group). The serum β2-MG levels of the four groups were determined and compared before with after the therapy. Results The difference between the serum β2-MG in HD group detected at the first day before and after the therapy was insignificant difference [( 53.49±1.15 ) mg/L vs (49.10±2.31 ) mg/L ] (P > 0.05 ). The difference between the serum β2-MG in HD group detected at the first day before and after the therapy six months later [(55.63±1.30) mg/L] was significant difference (P <0.05). The serum levels at the first day and six months later after the therapy detected in HFD group, HDF group and HD+AP group were significantly decreased compared with those of the first day before the therapy (P < 0.05 ). Furthermore,the serum β2-MG level decreased in HD+AP group was more significant than HFD group and HDF group at six months later (P <0.05). Conclusions Hemodialysis can not clear the serum β2-MG. High flux dialysis, hemodiafiltration and resin absorptive devices associated hemedialysis can clear β2-MG effectively, while resin absorptive devices associated hemodialysis has the better effection after six months.
