Brief Summary

This study is an extension of our current work measuring changes in brain energy metabolism in response to chronic hypoxia. The purpose of this study is to explore and quantify the relationships between HIF-1, inflammatory cytokines, and in vivo markers of brain bioenergetics in patients who have recovered from Severe vs. Asymptomatic  COVID-19 infections.

Aim 1: To quantify alterations in brain phosphocreatine (PCr) and adenosine triphosphate (ATP), in patients recovered from severe vs. asymptomatic cases of COVID-19.

Aim 2: To quantify peripheral hypoxia-inducible factor-1 (HIF-1) and inflammatory cytokine levels in patients recovered from severe vs. asymptomatic cases of COVID-19.

Aim 3: To explore the association between the peripheral HIF-1 and cytokine levels in both participant groups, in relation to PCr and ATP concentrations in the brain.

Using phosphorus-31 magnetic resonance spectroscopy (31P-MRS) brain scans, combined with analysis of serum HIF-1 and inflammatory cytokine levels in patients fully recovered from severe vs. asymptomatic COVID-19, will enable us to investigate the following Research Hypotheses:

1.     Recovered COVID-19 patients who experienced respiratory distress and required hospitalization (herein referred to as H-COVID-19) will show increased PCr and decreased ATP relative to patients recovered from asymptomatic COVID-19.

2.     Recovered H-COVID-19 patients will have higher levels of peripheral HIF-1 and inflammatory cytokines, when compared to patients recovered from asymptomatic COVID-19.

3.     Peripheral HIF-1 levels will be correlated with the changes in PCr levels in both recovered H-COVID-19 patients and recovered asymptomatic COVID-19.
