COVID-19 affects multiple organ-systems. Recent studies have indicated perturbations in the circulating metabolome linked to COVID-19 severity. However, several questions pertain with respect to the metabolome in COVID-19. We performed an in-depth assessment of 1129 unique metabolites in 27 hospitalized COVID-19 patients and integrated results with large-scale proteomic and immunology data to capture multi-organ system perturbations. More than half of the detected metabolic alterations in COVID-19 were driven by patient-specific confounding factors ranging from comorbidities to xenobiotic substances. Systematically adjusting for this, a COVID-19 specific metabolic imprint was defined which, over time, underwent a switch in response to SARS-CoV-2 seroconversion. Integration of the COVID-19 metabolome with clinical, cellular, molecular and immunological severity scales further revealed a network of metabolic trajectories aligned with multiple pathways for immune activation, and organ damage including neurological inflammation and damage. Altogether, this resource refines our understanding of the multi organ-system perturbations in severe COVID-19 patients. This article is protected by copyright. All rights reserved.
