Long COVID (LC) encompasses a constellation of long-term symptoms experienced by at least 10% people after the initial SARS-CoV-2 infection, and so far it has affected about 65 million people.

Despite the recent and increasing knowledge surrounding COVID-19 infection, underlying mechanisms of persistence symptoms for a long time after acute infection are still not completely understood. Here, multiplatform mass spectrometry-based approach was used metabolomic lipidomic profiling human plasma samples from Long COVID patients (n = 40) to reveal mitochondrial dysfunction when compared with individuals fully recovered mild 40). Untargeted analysis using CE-ESI(+/−)-TOF-MS GC-Q-MS performed. Additionally, LC-ESI(+/−)-QTOF-MS based on an in-house library revealed 447 lipid species identified high confidence annotation level.
