Am J Clin Nutr:结肠癌患者术前静脉注射ω-3脂肪酸的影响

术后炎症反应有助于组织的愈合和恢复,但过度炎症与术后并发症有关,n-3(ω-3)PUFAs可调节炎症反应,可能有助于防止促炎症级联。本研究旨在探究围术期静脉注射n-3 PUFAs对结肠癌手术中炎症细胞因子的影响。

本研究是一项随机、双盲、安慰剂对照的临床试验。44名接受非转移癌选择性结肠切除术的患者,随机分配在手术前夜和术后早晨进行2次静脉注射n-3 PUFA或生理盐水对照。在6个围手术期时间点进行血液采样,以了解血清中细胞因子的变化和LPS刺激的全血样本和白细胞膜脂肪酸谱。

结果,23名患者接受生理盐水,21名患者接受n-3 PUFAs。除开放性切除外,各组间患者和手术的特征相同(生理盐水n = 5,n-3 PUFA n = 0,P = 0.056)。LPS刺激后的体外IL-6在术后第一天n-3 PUFA组显著升高(P = 0.014),但在术后第二天无差异(P = 0.467)。术后第4天,n-3 PUFA组的白细胞计数较高(P = 0.029)。n-3 PUFA组有更多的患者出现感染性并发症(8例VS 3例,P = 0.036)。血清IL-6、IL-10、C反应蛋白和住院时间没有总体差异。给予n-3 PUFAs可使白细胞膜n-3 PUFAs含量迅速增加。

总之,该研究结果表明,在n-3 PUFA组中,未发现与血清和LPS刺激的细胞因子有明显关系,但出乎意料的是,发生了更多的感染性并发症。因此,在本研究范围内,围手术期静脉注射n-3 PUFA乳剂作为独立输液在原发性吻合术的结肠切除术中的非标使用需要谨慎。
