There is an urgent need to identify cellular/molecular mechanisms responsible for severe COVID-19 progressing to mortality. We performed untargeted/targeted lipidomics and focused biochemistry on 127 plasma samples and found elevated metabolites associated with secreted phospholipase A2 (sPLA2) activity and mitochondrial dysfunction in severe COVID-19 patients. Deceased COVID-19 patients had higher levels of circulating, catalytically active sPLA2 Group IIA (sPLA2-IIA), with a median value 9.6-fold higher than mild patients and 5.0-fold higher than severe COVID-19 survivors. Elevated sPLA2-IIA levels paralleled several indices of COVID-19 disease severity (e.g., kidney dysfunction, hypoxia, multiple organ dysfunction). A decision tree generated by machine learning identified sPLA2-IIA levels as a central node in stratifying patients that succumbed to COVID-19. Random forest analysis and LASSO-based regression analysis additionally identified sPLA2-IIA and blood urea nitrogen (BUN) as the key variables among 80 clinical indices in predicting COVID-19 mortality. The combined PLA-BUN index performed significantly better than either alone. An independent cohort (n=154) confirmed higher plasma sPLA2-IIA levels in deceased patients vs. severe or mild COVID-19, with the PLA-BUN index-based decision tree satisfactorily stratifying mild, severe, and deceased COVID-19 patients. With clinically tested inhibitors available, this study supports sPLA2-IIA as a therapeutic target to reduce COVID-19 mortality.

Science in the 20th century yielded a basic understanding of the key macro and micro nutritional requirements for most humans. This resulted in a one-size-fits-all approach to nutrition, which has been impactful in reducing malnutrition and diseases resulting from nutrient deficiencies. However, evolutionary studies reveal that humans adapted to their ancestral diets and local environments, which resulted in population- or region-specific genetic variation. Consequently, individuals in large modern populations with diverse genetic ancestries, such as the US, may have a wide range of metabolic responses to the same food or diet, calling into question the one-size-fits-all dietary approach. Precision nutrition (sometimes called personalized nutrition, nutrigenetics, or nutritional genetics) is an emerging field of science which explores the concept of diets tailored to an individual’s personal biology.
