Abstract
The clinical outcome and disease severity in coronavirus disease-2019 (COVID-19) are heterogeneous, and the progression or fatality of the disease cannot be explained by a single factor like age or comorbidities. In this study, we used system-wide network-based system biology analysis using whole blood RNA sequencing, immune-phenotyping by flow cytometry, plasma metabolomics, and single cell-type metabolomics of the monocytes to identify the potential determinants of COVID-19 severity at the personalized and group level. Digital cell quantification and immune-phenotyping of the mononuclear phagocytes indicated a substantial role in coordinating the immune cells that mediate the COVID-19 severity. Stratum-specific and personalized genome-scale metabolic modeling indicated monocarboxylate transporter family genes (e.g., SLC16A6), nucleoside transporter genes (e.g., SLC29A1), and metabolites such as α-ketoglutarate, succinate, malate, and butyrate, could play a crucial role in COVID-19 severity. Metabolic perturbations targeting the central metabolic pathway (TCA-cycle) can be an alternate treatment strategy in severe COVID-19.
