Summary
Longitudinal metabolomic profiling reveals key metabolic shifts associated with COVID-19 severity and progression. These findings may identify at-risk patients and offer novel therapeutic targets for coronavirus disease 2019.
Area of Science:
- Metabolomics
- Infectious Diseases
- Biochemistry
Background:
- Coronavirus disease 2019 (COVID-19) presents a wide range of clinical severity.
- Early interventions for high-risk patients are crucial to reduce mortality and healthcare costs.
Purpose of the Study:
- To investigate the association between longitudinal metabolomic profiles and the severity and progression of COVID-19.
- To identify potential metabolic biomarkers for predicting COVID-19 outcomes.
Main Methods:
- Analysis of metabolomic profiles from hospitalized COVID-19 patients in the BEAT-COVID cohort, sampled longitudinally over up to 60 days.
- Daily assessment of disease severity using the Severity of Coronavirus Disease Assessment (SCODA) score.
- Statistical analysis using linear mixed-effect models to identify associations between metabolites and disease severity.
Main Results:
- Significant perturbations were observed in the tryptophan-kynurenine pathway, linoleic acid derivatives, endocannabinoids, and sphingosines, correlating with COVID-19 severity and progression.
- Metabolic changes were associated with immune markers indicative of COVID-19 severity.
- Potential differences between study waves may be linked to corticosteroid treatment.
Conclusions:
- Longitudinal metabolomic profiling can reveal key metabolic alterations in COVID-19 patients.
- Identified metabolites related to oxidative stress and inflammation may serve as biomarkers for disease progression.
- These findings could aid in identifying at-risk patients and suggest potential therapeutic targets for COVID-19.
