| Project Title: | Reinforcing the Evidence of Mitochondrial Dysfunction in Long COVID Patients using a Multiplatform Mass Spectrometry-based Metabolomics Approach |
| Project Summary: | Despite the recent and increasing knowledge surrounding COVID-19 infection, the underlying mechanisms of the persistence of symptoms long time after the acute infection are still not completely understood. Here, a multiplatform mass spectrometry-based approach was used for metabolomic and lipidomic profiling of human plasma samples from Long COVID patients (n=40) to reveal mitochondrial dysfunction when compared with individuals fully recovered from acute mild COVID-19 (n=40). Untargeted metabolomic analysis using CE-ESI(+/–)-TOF-MS and GC-Q-MS was performed. Additionally, a lipidomic analysis using LC-ESI(+/–)-QTOF-MS based on an in-house library revealed 471 lipid species identified with high confidence annotation level. The integration of complementary analytical platforms has allowed a comprehensive metabolic and lipidomic characterization of plasma alterations in Long COVID disease that found 46 relevant metabolites which allowed to discriminate between Long COVID and fully recovered patients. We report specific metabolites altered in Long COVID, mainly related to a decrease in the amino acid metabolism and ceramide plasma levels, and an increase in the tricarboxylic acid (TCA) cycle, reinforcing the evidence of an impaired mitochondrial function. The most relevant alterations shown in this study will help to better understand the insights of Long COVID syndrome by providing a deeper knowledge of the metabolomic basis of the pathology. |
