摘要
背景:临床发现肾移植前维持性血液透析患者外周血单个核细胞核因子κB的活性异常增高。目的:了解肾移植前维持性血液透析患者外周血单个核细胞核因子κB的活性,并探讨其与超敏C-反应蛋白水平、营养不良的关系。方法:检测肾移植前维持性血液透析患者与健康对照人群营养状态、人体学指标、血液生化指标、外周血单个核细胞核因子κB活性及血清超敏C-反应蛋白水平,据血清超敏C-反应蛋白水平将维持性血液透析患者分为非炎症组(<3mg/L)和微炎症组(≥3mg/L)。结果与结论:①维持性血液透析患者单个核细胞核因子κB活性与血清超敏C-反应蛋白水平显著高于健康对照组(P<0.001)。②微炎症组营养不良数量及程度、改良主观全面营养评价评分、单个核细胞核因子κB活性及血清超敏C-反应蛋白水平显著高于非炎症组(P≤0.001或P<0.01或P<0.05)。③非炎症组血红蛋白、血清白蛋白、血清前白蛋白、中臂肌围、中臂围、握力均显著低于健康对照组(P≤0.001),单个核细胞核因子κB活性显著高于健康对照组(P≤0.001),血清超敏C-反应蛋白水平与健康对照组间差异无显著性意义(P>0.05)。提示肾移植前维持性血液透析患者普遍存在外周血单个核细胞核因子κB异常活化;随炎症反应加重,C-反应蛋白水平升高,单个核细胞核因子κB活性进一步增强,营养不良加重;说明核因子κB活性可能较血清C-反应蛋白水平更早发现维持性血液透析患者的微炎症状态及预测营养不良。
BACKGROUND： The nuclear factor-κB （NF-κB） activity in peripheral blood mononuclear cells （PBMCs） from patients undergoing maintenance hemodialysis （MHD） before renal transplantation has been found to be increased abnormally. OBJECTIVE： To investigate NF-κB activity in PBMCs from patients underlying MHD before renal transplantation and its correlation with high sensitive C-reactive protein （hs-CRP） levels and malnutrition. METHODS： The nutritional status, anthropometric indicators, blood biochemistry, the NF-κB p65 activity in PBMCs and serum hs-CRP level in 71 patients undergoing MHD before renal transplantation and healthy controls were detected. MHD patients were divided into non-inflammatory group （ 3 mg/L） and slight inflammation group （≥ 3 mg/L） according to the hs-CRP levels. RESULTS AND CONCLUSION： NF-κB activity in PBMCs and serum hs-CRP levels were significantly higher in MHD patients than in healthy controls （P 0.001）. The number of malnutrition patients, the score of modified quantitative subjective global assessment of nutrition （MQSGA）, and the NF-κB activity in PBMCs as well as serum hs-CRP level were significantly higher in the slightly inflammatory group than in the non-inflammatory group （P ≤ 0.001 or P 0.01 or P 0.05）. The hemoglobin, serum albumin, serum prealbumin, mid-arm muscle circumference, mid-arm circumference and grasp force were all significantly lower in the non-inflammatory group than in the non-inflammatory group （P ≤0.001） and the NF-κB activity in PBMCs were significantly higher in the non-inflammatory group than in the healthy control group （P ≤ 0.001）, there was no significant difference in serum hs-CRP levels between non-inflammatory group and healthy control group （P 0.05）. Results showed that NF-κB was abnormally activated in PBMCs in patients underlying MHD before renal transplantation; with worsened inflammatory reaction, serum hs-CRP levels and the abnormal activation of NF-κB would be increased and t
