Introduction

The COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2, has had an unprecedented global impact, affecting millions of lives and overwhelming healthcare systems worldwide. Despite extensive research, the pathophysiology of COVID-19 and the factors contributing to the variability in disease severity and outcomes remain incompletely understood. While some individuals experience mild or asymptomatic infections, others suffer from severe disease characterized by Acute Respiratory Distress Syndrome (ARDS), multi-organ failure, and even death. This variability underscores the need for reliable biomarkers that can predict disease severity and prognosis, thereby aiding in the early identification of high-risk patients and optimizing clinical management. Metabolomics, the comprehensive study of small molecules or metabolites within biological systems, offers a powerful approach to elucidate the biochemical changes associated with SARS-CoV-2 infection [1].

Description

Metabolites are the end products of cellular processes and provide a snapshot of the physiological state of an organism. By profiling the metabolites in biological samples such as blood, urine, or tissues, metabolomics can reveal alterations in metabolic pathways that occur in response to viral infection [2]. These metabolic changes can serve as potential biomarkers for disease severity and prognosis, offering insights into the underlying mechanisms of COVID-19 and identifying targets for therapeutic intervention.

Recent studies have highlighted significant metabolic alterations in SARS-CoV-2 infected patients, reflecting the complex interplay between the virus and host metabolism. Key metabolic pathways, including those involved in energy production, amino acid metabolism, lipid metabolism, and the immune response, are profoundly affected by the infection. For instance, disruptions in glycolysis and the Tricarboxylic Acid (TCA) cycle indicate a shift in energy metabolism, while alterations in amino acid levels suggest an impact on protein synthesis and immune function [3]. Additionally, changes in lipid metabolites point to modifications in membrane dynamics and inflammatory responses. This review aims to provide a comprehensive overview of metabolomic profiling studies conducted on SARS-CoV-2 infected patients, focusing on the identification of potential biomarkers for disease severity and prognosis [4]. By integrating findings from various studies, we seek to highlight the most consistent and clinically relevant metabolic changes associated with COVID-19. Understanding these metabolic signatures can enhance our ability to predict disease outcomes, guide therapeutic strategies, and improve patient management [5].

Conclusion

The application of metabolomic profiling in the study of SARS-CoV-2 infection has yielded valuable insights into the biochemical perturbations associated with COVID-19. This approach has identified several metabolites and metabolic pathways that are significantly altered in infected patients, providing potential biomarkers for assessing disease severity and prognosis. The integration of metabolomic data with clinical parameters can enhance the precision of risk stratification and inform personalized treatment strategies.
