【摘要】:目的:通过多频生物电阻抗法对持续性非卧床腹膜透析(Continuous AmbulatoryPeritoneal Dialysis,CAPD)患者容量状态进行评估,寻找CAPD患者容量负荷影响因素,并探讨患者容量负荷与营养不良及炎症之间的关系。 方法:选取来自沈阳军区总医院肾内科2006~2013年收治的持续非卧床腹膜透析(CAPD)患者60例作为研究对象进行横断面研究(其中男35例,女25例)。并选择了年龄和性别比例相同的健康人30例作为对照组。使用多频生物电阻抗分析仪测定患者的容量状态,根据细胞外液/总液体(ECW/TBW)的比值将透析患者分为容量超负荷组(ECW/TBW≥0.39),以及容量正常组(ECW/TBW<0.39)。同时测量血压,检测血清白蛋白(Alb)、总蛋白(TP)、血清肌酐(Scr)、血浆尿素氮(BUN)及其他生化指标和炎症指标C-反应蛋白(CRP);采集空腹血、24小时的尿液和腹膜透析超滤液用来评价患者的透析的充分性及残余肾功能。寻找上述指标中那些因素影响CAPD患者的容量负荷,并探讨营养不良和炎症与容量负荷影响因素之间的关系。 结果:1.病例组和健康组的比较:CAPD患者的ECW、TBW、ECW/TBW、细胞外液/细胞内液(ECW/ICW)均高于健康对照组(p<0.05),差异有统计学意义。而ICW含量两组无差异(p>0.05)。 2.60例CAPD患者容量超负荷组(34例)ECW、ECW/ICW、收缩压、年龄、C-反应蛋白都高于容量正常组(26例)而容量负荷组血清白蛋白、残肾功能、每周尿素清除指标、每周肌酐清除率则低于容量正常组(p<0.05),差异有统计学意义。 3.营养不良组(37例)患者ECW/ICW、年龄、收缩压、C-反应蛋白都高于营养正常组(23例)(p<0.05),差异有统计学意义。 4.炎症组(31例)患者ECW、ECW/ICW、血清白蛋白、收缩压、年龄均高于未合并炎症组(29例),而每周肌酐清除率低于未合并炎症组(p<0.05),差异有统计学意义。 5.容量相关指标ICW与血肌酐(Scr)、血尿素氮(BUN)呈正相关,,与年龄、尿素清除指数(Kt/v)呈负相关;ECW与收缩压、Scr、BUN、CRP呈正相关,与Kt/v、Alb呈负相关;TBW与收缩压、Scr、BUN、CRP呈正相关,年龄、Kt/v呈负相关;ECW/TBW与年龄、收缩压、CRP呈正相关,与Alb、TP呈负相关;ECW/ICW与年龄、收缩压、CRP呈正相关,与Alb、TP呈负相关。 结论:1.60例CAPD患者容量超负荷的所占比例是56.67%,表现特点为ECW的增加、ECW/TBW、ECW/ICW的比值升高。 2.CAPD患者容量超负荷的影响因素包括:年龄、SBP、RRF、Kt/v、Ccr、Alb、CRP水平。 3.CAPD患者容量超负荷组的C-反应蛋白高于容量正常组,而血清白蛋白则低于容量正常组。表明在容量超负荷的CAPD患者中普遍存在营养不良和炎症。 4..容量状态指标与营养指标、炎症状态、年龄、收缩压、Kt/v之间具有很强的相关性。

Methods: a cross-sectional study was conducted in 60 (CAPD) patients with continuous ambulatory peritoneal dialysis (35 males and 25 females) from 2006 to 2013 in Department of Nephrology, Shenyang military region General Hospital. 30 healthy people with the same age and sex ratio were selected as control group. According to the ratio of extracellular fluid to total fluid (ECW/TBW), dialysis patients were divided into two groups: volume overload group (ECW/TBW 鈮
