The metabolic alterations caused by SARS-CoV-2 infection reflect disease progression. To analyze molecules involved in these metabolic changes, a multiomics study was performed using plasma from 103 patients with different degrees of COVID-19 severity during the evolution of the infection. With the increased severity of COVID-19, changes in circulating proteomic, metabolomic, and lipidomic profiles increased. Notably, the group of severe and critical patients with high HRG and ChoE (20:3) and low alpha-ketoglutaric acid levels had a high chance of unfavorable disease evolution (AUC = 0.925). Consequently, patients with the worst prognosis presented alterations in the TCA cycle (mitochondrial dysfunction), lipid metabolism, amino acid biosynthesis, and coagulation. Our findings increase knowledge regarding how SARS-CoV-2 infection affects different metabolic pathways and help in understanding the future consequences of COVID-19 to identify potential therapeutic targets.
由严重急性呼吸综合征冠状病毒2（SARS-CoV-2）感染引起的代谢改变反映了疾病进展。为了分析参与这些代谢变化的分子，在感染过程中，对103例不同严重程度的新型冠状病毒肺炎（COVID-19）患者的血浆进行了多组学研究。随着COVID-19严重程度的增加，循环蛋白质组、代谢组和脂质组谱的变化也增加。值得注意的是，高纤连蛋白（HRG）和二十碳三烯酸（ChoE，20:3）水平高且α-酮戊二酸水平低的重症和危重症患者疾病进展不良的可能性很高（曲线下面积[AUC]=0.925）。因此，预后最差的患者在三羧酸循环（线粒体功能障碍）、脂质代谢、氨基酸生物合成和凝血方面出现了改变。我们的研究结果增加了关于SARS-CoV-2感染如何影响不同代谢途径的知识，并有助于理解COVID-19的未来后果，以确定潜在的治疗靶点。
