Abstract

Background: This study aimed to investigate the role of oxylipins and lipid mediators in Pulmonary Embolism (PE), a serious cardiovascular condition associated with high morbidity and mortality rates.

Methods: A total of 6,365 hospitalized patients with thrombosis and 200 healthy individuals were recruited as the control group from 2015 to 2023. Thrombus type, coagulation, and lipid-related parameters were statistically analysed. Additionally, lipidomic characteristics of serum samples from the PE and control groups were examined via LC-MS/MS for the first time.

Results: Among the 6,365 hospitalized patients with thrombosis, 72.1% (4,587/6,365) had venous thromboembolism (VTE). Within the VTE group, the incidence of PE was 12.1% (555/4,587). In comparison to the healthy control (HC) group, the PE group exhibited significant elevations in coagulation-related parameters, such as factor VIII (F VIII) and von Willebrand factor (vWF) activities, while antithrombin III (AT III) and factor XII (F XII) activities were notably reduced. Lipid-related parameters, including serum cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A (apoA), were significant reductions in PE patients (P < 0.0001), with areas under the curve (AUCs) exceeding 0.9. LC-MS/MS analysis of serum samples revealed 118 oxidized lipid metabolites. Compared to the HC group, the PE group exhibited 10 upregulated oxidized lipid metabolites, with the most significant difference observed in 20-hydroxyPGF2α derived from arachidonic acid (ARA). The study identified upregulated oxidized lipid metabolites primarily linked to the ARA metabolism signalling pathway.

Conclusion: This research indicates a notable correlation between lipid metabolism and the occurrence and development of PE. Specifically, upregulation of the arachidonic acid metabolism signalling pathway may be an important pathogenic factor for PE, and 20-hydroxyPGF2α derived from ARA has potential as a biomarker for PE disease.

鉴定肺栓塞中的氧脂素和脂质介质。

背景：本研究旨在探讨氧脂素和脂质介质在肺栓塞中的作用：本研究旨在探讨氧脂和脂质介质在肺栓塞（PE）中的作用，肺栓塞是一种与高发病率和死亡率相关的严重心血管疾病：方法：从 2015 年至 2023 年，共招募了 6365 名住院血栓形成患者和 200 名健康人作为对照组。对血栓类型、凝血和血脂相关参数进行统计分析。此外，还首次通过 LC-MS/MS 对 PE 组和对照组血清样本的脂质体特征进行了研究：在 6,365 名住院血栓形成患者中，72.1%（4,587/6,365）患有静脉血栓栓塞症（VTE）。在 VTE 组中，PE 的发生率为 12.1%（555/4,587）。与健康对照（HC）组相比，PE 组的凝血相关参数，如因子 VIII（F VIII）和 von Willebrand 因子（vWF）活性显著升高，而抗凝血酶 III（AT III）和因子 XII（F XII）活性则明显降低。血脂相关参数，包括血清胆固醇（TC）、高密度脂蛋白胆固醇（HDL-C）、低密度脂蛋白胆固醇（LDL-C）、载脂蛋白 A（apoA），在 PE 患者中均显著降低（P 结论：PE 患者的血脂相关参数显著降低：这项研究表明，脂质代谢与 PE 的发生和发展之间存在明显的相关性。具体而言，花生四烯酸代谢信号通路的上调可能是 PE 的重要致病因素，而从 ARA 中提取的 20-hydroxyPGF2α 有可能成为 PE 疾病的生物标志物。

期刊介绍： Lipids in Health and Disease is an open access, peer-reviewed, journal that publishes articles on all aspects of lipids: their biochemistry, pharmacology, toxicology, role in health and disease, and the synthesis of new lipid compounds. Lipids in Health and Disease is aimed at all scientists, health professionals and physicians interested in the area of lipids. Lipids are defined here in their broadest sense, to include: cholesterol, essential fatty acids, saturated fatty acids, phospholipids, inositol lipids, second messenger lipids, enzymes and synthetic machinery that is involved in the metabolism of various lipids in the cells and tissues, and also various aspects of lipid transport, etc. In addition, the journal also publishes research that investigates and defines the role of lipids in various physiological processes, pathology and disease. In particular, the journal aims to bridge the gap between the bench and the clinic by publishing articles that are particularly relevant to human diseases and the role of lipids in the management of various diseases.
