【摘要】目的 观察超纯透析液对慢性血透患者血清白介素-1、白介素-6、C反应蛋白、脂蛋白(a)、2微球蛋白的影响。方法 长期血透患者21例，随机分为超纯透析液和常规透析液组，均用低通量聚砜膜，前瞻性观察两组入组前1周、入组后1周、1月、6月和12月透前指标有无差异。并在上述点观察各组透析中120分钟、透后即刻上述指标较透前有无变化。结果 常规透析或超纯透析组在任一观察点的单次透析中120分钟和透析后即刻，上述指标较透前水平没有变化。12月后，超纯组透前血清白介素-1较对照明显下降(P＜0.05)，对照组血清脂蛋白(a)水平较超纯组明显升高 (P＜0.05)。结论 良好的透析膜生物相容性有利稳定透析过程对炎症指标的影响，长期使用超纯透析液能降低患者透前血清白介素-1水平，且维持血清Lp(a)水平稳定，它可能有利于改善长期血透患者微炎症状态和相关并发症。

【Abstract】 Objective The aim was to observe the effects of ultrapure dialysate (UPD) on serum interleukin-6, interleukin-1 (IL-1), C-reactive protein, β2-microglobulin, and lipoprotein(a) [Lp(a)]. Methods A controlled prospective randomized study was carried out on 21 stable patients dialyzed on low-flux synthetic polysulphone membrane and assigned to either UPD or conventional dialysate (CD). Blood samples were collected at pre-dialysis, 120 minutes later during the dialysis and immediately post-dialysis. The variables were measured one week before the study, and one week, one month, six months and twelve months during the study. Results All parameters were not changed during the session. Lp(a) was significantly higher in CD group (283.88+145.80 vs 120.90+122.11mg/L, p <0.05), and IL-1βwas lower in UPD group (49.22+14.18 vs 68.05+20.34 pg/ml, p <0.05) at the end of study. Conclusions Biocompatible membrane is first of all to lessen dialysis related chronic inflammation, and ultrapure dialysate should further decrease the high risk of inflammation related atherosclerosis through decreasing IL-1β and preventing rise of Lp(a).
