There is limited information available regarding the association of plasma free fatty acids (FFA) and inflammation mediators with ischemic stroke. At the same time, new treatment strategies are being pursued. The aim of this study was to carry out a thorough analysis of inflammation with multiple FFA-derivative mediators after and ischemic stroke and standard treatment. HPLC separations of 17 eicosanoids were performed using an Agilent Technologies 1,260 liquid chromatograph. The profiles of the esters of fatty acids were labelled by means of gas chromatography. FFA, and eicosanoid profiles in the group of patients after ischemic stroke significantly differed from the profile of the control group. Studies confirmed the involvement of derivative synthesis pathways responsible for the inflammation, especially palmitic acid (9 and 13 HODE), arachidonic acid, EPA and DHA. Arachidonic acid derivatives were synthesised on 5LOX, 15 LOX and COX pathways with the participation of prostaglandins while omega 3 derivatives strengthened the synthesis of resolvins, RevD1 in particular. The ability to accelerate the quenching of inflammation after ischemic stroke seems to be a promising strategy of stroke treatment in its early stage. In this context, our study points to lipoxins, RevD1, and 9, 13 HODE as the most important derivatives.
关于血浆游离脂肪酸 (FFA) 和炎症介质与缺血性中风的关联,目前可用的信息有限。与此同时,新的治疗策略正在被探索。本研究的目的是在缺血性中风后和标准治疗后,对多种 FFA 衍生介质的炎症进行全面分析。使用安捷伦技术 1260 液相色谱仪对 17 种类二十烷酸进行了 HPLC 分离。脂肪酸酯的图谱通过气相色谱法标记。与对照组相比,中风后患者组的 FFA 和类二十烷酸图谱明显不同。研究证实了参与炎症的衍生合成途径的参与,特别是棕榈酸(9 和 13 HODE)、花生四烯酸、EPA 和 DHA。花生四烯酸衍生物通过 5LOX、15LOX 和 COX 途径与前列腺素一起合成,而 ω3 衍生物则增强了 resolvins 的合成,特别是 RevD1。在缺血性中风后加速炎症熄灭的能力似乎是中风早期治疗的一个有前途的策略。在这方面,我们的研究指出脂氧素、RevD1 以及 9、13 HODE 是最重要的衍生物。
