替米沙坦改善维持性血液透析患者微炎症和氧化应激状态

目的 探讨替米沙坦对维持性血液透析(maintenance hemodialysis,MHD)患者微炎症及氧化应激状态的影响.方法 60 例行MHD 治疗的慢性肾衰竭患者,随机分为替米沙坦治疗组(T 组,30 例)和非替米沙坦治疗组(NT 组,30 例),并设健康对照组(30 例).检测治疗前及治疗24 周时血清高敏C 反应蛋白(high sensitivity C-reactive protein,hs-CRP)、白细胞介素6(interleukin-6,IL-6)、肿瘤坏死因子α(tumor necrosis factor-α,TNF-α)、脂质过氧化物丙二醛(malondialdehyde,MDA)、前白蛋白(prealbumin,PA)的水平.结果与健康对照组比较,MHD 患者hs-CRP 升高,分别为(8.1 ± 2.6)mg/L 和(1.5 ± 0.7)mg/L,IL-6 升高,分别为(349.0 ± 52.4)ng/L 和(53.6 ± 15.0)ng/L,TNF-α升高,分别为(8.1 ± 2.2)ng/L 和(2.1 ± 0.8)ng/L,MDA 升高,分别为(7.3 ± 3.2)μmol/L 和(3.5 ± 0.9)μmol/L,差异均有统计学意义(P ＜ 0.05);PA 降低,分别为(20.6 ± 7.3)mg/dl 和(28.4 ± 4.0)mg/dl,差异有统计学意义(t =-6.542,P ＜ 0.05 ).治疗前T 组与NT 组hs -CR P、IL- 6、TN F- α、MD A、PA 水平差异无统计学意义(P ＞ 0.05 ).替米沙坦治疗24 周时,与NT 组相比,T 组血清hs-CRP 降低,分别为(5.6 ± 1.8)mg/L 和(8.2 ± 2.8)mg/L,IL-6 降低,分别为(218.6 ± 45.9)ng/L 和(363.0 ± 67.4)ng/L,TNF-α降低,分别为(5.3 ± 1.7)ng/L 和(8.7 ± 2.3)ng/L,MDA 降低,分别为(4.6 ± 2.2) μmol/L 和(7.5 ± 3.7)μmol/L),差异均有统计学意义(P＜ 0.05);PA 升高,分别为(25.3 ± 6.7)mg/dl 和(20.0 ± 7.7)mg/dl,差异有统计学意义(t =-3.362,P ＜0.05).结论替米沙坦可改善MHD 患者微炎症、氧化应激及营养不良状态.

Telmisartan improves micro-inflammation and oxidative stress in patients with maintenance hemodialysis

Objective To evaluate the effect of telmisartan on micro-inflammation and oxidative stress in maintenance hemodialysis(MHD) patients.Methods Sixty stable MHD patients and 30 healthy volunteers(control) were involved in this study.The MHD patients were randomly divided into telmisartan treatment group(group T;n=30) or non-telmisartan treatment group(group NT;n=30).Patients in group T took telmisartan at a dose of 80mg per day for 24 weeks.Plasma high-sensitive C-reactive protein(hs-CRP),interleukin-6(IL-6),t...
