炎性反应因子与维持性血液透析患者透析中高血压的相关性

目的 研究维持性血液透析患者透析中高血压(IDH)与炎性反应因子的相关性.方法 选择维持性血液透析患者40例,分为IDH组和非IDH组,每组20例.在透析前及透析1、2、4h分别采血,测定C反应蛋白(CRP)、白细胞介素(IL)-1 β、IL-6、肿瘤坏死因子(TNF)-α水平,分析各因素与血压的相关性.结果 IDH组随透析的进行,CRP、IL-1β、IL-6、TNF-α呈升高趋势,非IDH组随透析进行升高趋势不明显；相关性分析显示,CRP(r=0.3652)、IL-1β(r=0.3261)、IL-6 (r=0.3156)、TNF-α(r=0.3324)与血压呈正相关(P＜0.01).结论 CRP、IL-1β、TNF-α、IL-6与IDH存在相关性.

Relevance between inflammatory factors and intradialytic hypertension in patients with maintenance hemodialysis

Objective To study the relationship between intradialytic hypertension (IDH) and inflammatory factors in patients with maintenance hemodialysis.Methods Forty maintenance hemodialysis patients were involved,including 20 patients with IDH (IDH group) and 20 patients without IDH(non-IDH group) during hemodialysis.All of them had no sign of acute infections or other progressive disease.The levels of C-reactive protein (CRP),interleukin (IL)-1 β,IL-6,tumor necrosis factor (TNF)-α were measured by enzyme-linked immunosorbent assay (ELISA) before hemodialysis and 1,2,4 h after hemodialysis.The correlation of hypertension to CRP,IL-1 β,IL-6,TNF-α was analyzed.Results The levels of CRP,IL-1β,IL-6,TNF-α were increased in IDH group with the progress of hemodialysis,but were stable innon-IDH group.Logistic regression analysis indicated that there were positive correlations between CRP (r =0.3652),IL-1β (r =0.3261 ),IL-6(r =03156),TNF- α (r =0.3324) and blood pressure during hemodialysis (P ＜ 0.01 ).Conclusion The levels of CRP,IL-1β,TNF-α,IL-6 are positively related to the IDH in maintenance hemodialysis patients.
