患者血清脂联素及炎症反应对腹膜透析及未透析患者营养不良的影响

目的探讨血清脂联素（ADPN）及炎症反应对腹膜透析及未透析的终末期肾病患者营养不良的影响。方法调查45例CAPD治疗患者（腹透组）,32例未透析患者（未透析组）及30例健康人（正常对照组）,用双抗夹心法酶联免疫吸附试验（ELISA）测定三组的血清脂联素,用血清C反应蛋白（CRP）评估三组人群的炎症状态,采用MDRD方程计算肾小球滤过率,以评估患者的残余肾功能,采用主观综合性营养评估（SGA）、白蛋白（ALB）、前白蛋白（PA）等患者的营养状况。结果①与对照组相比,腹透组、未透析组患者的血清ADPN、CRP水平升高,而血清ALB水平下降,且腹透组的ADPN明显高于未透析组（P〈0.05）。②腹透组中,营养不良的总发生率为56.5%,与营养良好的患者相比,营养不良患者的透析龄长、ADPN、CRP明显升高,ALB、PA明显下降（P〈0.05）。③Pearson相关分析表明CAPD患者中,ADPN与ALB显著负相关,与CRP无统计学相关,CRP与ALB、BM I显著负相关。④未透析组中,营养不良的总发生率为34.4%,与营养良好患者相比,未透析组中营养不良患者的ADPN、CRP（P〈0.05）升高,ALB、PA降低（P〈0.05）。Pearson相关分析表明未透析组中,ADPN与ALB、PA、CRP无相关性,CRP与PA、ALB呈负相关。结论腹膜透析及未透析的终末期肾病患者血清ADPN、CRP水平均显著升高,且腹膜透析患者的ADPN水平明显高于未透析者;不论是腹膜透析还是未透析的ESRD患者,营养不良组的血清ADPN及CRP水平均明显升高、ALB均明显降低。

Effect of serum adiponectin and inflammatory reaction on malnutrition in patients with peritoneal dialysis

Objective To investigate the serum adiponectin in patients who were treated by continuous ambulatory peritoneal dialysis(CAPD) or out of dialysis.And to assess the effects of serum adiponectin(ADPN) and inflammatory reaction on malnutrition in CAPD patients.Methods 45 CAPD patients(peritoneal dialysis group,PD group),32 ESRD patients(undialysis group) and 30 healthy subjects(normal control group) were included in the study.The patients' nutritional status was evaluated by subject global assessment(SGA),seru...
