Why are certain vulnerable patient populations prone to developing severe COVID disease?

The novel SARS-CoV-2 virus has quickly become a global pandemic threat affecting nearly every aspect of public health and daily life. Originally described as a respiratory disease, accumulating evidence indicates that the resulting disease—COVID-19—causes increased inflammation and multiple organ damage including the vascular system, heart, kidneys, pancreas, liver, gastrointestinal tract, and brain. Taking into account the highly contagious nature of COVID-19, the many organs affected, and the degree to which it has already spread in the general population, it is imperative to understand the factors that drive severe COVID-19 disease manifestations and use this information to develop therapeutic strategies to treat it.

What if it would be possible to change the outcome of severe COVID disease into mild case scenario, or avert long term damage by changing the levels of certain molecules present in the blood?

To answer this question, we must first determine what is so unique about the blood of COVID patients. Our preliminary metabolic screen of COVID patients’ blood has revealed that certain molecules, or metabolites, are elevated in patients with severe disease when compared to patients with mild symptoms. Some of these molecules have already been shown by our team to activate immunity and inflammation in the type of cells that are primarily affected by the SARS-CoV-2 virus. Therefore, the aim of this project is to apply state-of-the-art, high-resolution mass spectrometry to characterize the blood metabolic profile of patients with severe COVID disease, with a focus on vulnerable populations including cancer patients, patients with cardiovascular disease, type II diabetes or obesity with different ethnic backgrounds.


SPARKing Impact: This study will provide new insights into the relationship between metabolism and COVID pathogenesis in a diverse population, and will reveal new potential metabolic targets for treating severely affected COVID patients.
