【摘要】 目的 观察应用不同组合的高通量透析模式对慢性肾脏病5期(CKD5)维持性血液透析(MHD)合并难治性高血压(RH)患者的降压效果及可行性分析。
方法 将符合条件的30例CKD5维持性透析合并难治性高血压患者按完全随机原则分为三组,第1组:单纯高通量透析(HPD)组10例,每周单纯行高通量透析3次;第2组:高通量透析+血液灌流 (HPD+HP)组10例,每周高通量透析2次,高通量透析+血液灌流1次;第3组:高通量血液透析+血液透析滤过(HPD+HDF)组10例,每周高通量透析 2次,血液透析滤过1次。开始入组前各组病人均行为期8周低通量血液透析,每周3次(洗脱期),治疗12周后再对比治疗前后血压的变化;同时测定治疗前后每一位患者血清甲状旁腺激素(iPTH)、血β2微球蛋白(β2-MG)浓度。
结果 HPD组、HPD+HP组及HPD+HDF组三个组治疗12周后血压、血iPTH、血 β2-MG 浓度都出现大幅度下降(P<0.01),差异有统计学意义,但三组间两两比较差异无统计学意义(P>0.05)。
结论 单纯高通量透析、高通量透析+血液灌流及高通量透析+血液透析滤过三种治疗手段对慢性肾脏病5期合并难治性高血压患者的血压控制都有很好的帮助,降压作用明显,并能对体内蓄积过多的血iPTH 、血 β2-MG有很好的清除作用。

【Abstract】 Objective To observe the antihypertensive effect and feasibility of different combination modes of high permeability dialysis(HPD) on maintenance hemodialysis(MHD) patients with refractory hypertension(RH) of chronic kidney disease 5(CKD5).
Methods 30 cases of MHD patients with RH of CKD5 were randomly divided into the following three groups (10 cases in each group):HPD group,given pure HPD 3 times a week;HPD+hemoperfusion (HP) group,given HPD twice a week and HPD+HP once a week;HPD+HDF(hemodiafiltration)group,given HPD twice a week and HDF once a week.Before being grouped,each patient underwent low permeability dialysis for 8 weeks with 3 times a week(washout period).After 12 weeks of treatment,changes of blood pressure were compared with those before treatment.Meanwhile,serum iPTH and β2-MG concentration of each patient before and after treatment were compared.
Results After 12 weeks of treatment,blood pressure,serum iPTH and β2-MG concentration of the HPD group,the HPD+HD group and the HPD+HDF group declined significantly(P<0.01),which showed statistically significant difference.But the comparisons between each group had no statistically significant difference(P>0.05).
Conclusion HPD,HPD+HD and HPD+HDF are all effective in controlling blood pressure of patients with CKD5 and RH.They have obvious antihypertensive effect and cleaning effect on blood iPTH and β2-MG.
