Severe COVID-19 illness can result in excessive inflammation throughout the body, including the lungs, heart and brain. University of Minnesota Twin Cities student Molly Gilligan recently published an article in the journal Cancer & Metastasis Reviews that studied the human body's robust inflammatory response to the SARS-CoV-2 virus, which is now recognized as a hallmark symptom.
According to the publication, controlling the body's inflammatory response to SARS-CoV-2 will likely be as important as antiviral therapies or a potential vaccine. Individual mediators -- called cytokines -- cause inflammation in response to tissue injury or infection. Mediators are a substance or structure that mediates a specific response in a bodily tissue.
Rather than blocking cytokines, medical staff could turn off virus-induced inflammation by broadly activating the body's natural inflammation-clearing activities.
"We are now recognizing the importance of controlling this robust inflammatory response in COVID-19 infection in order to reduce associated organ damage and mortality," said Gilligan, a student at the Medical School. "Finding new ways to dampen the body's inflammatory response to COVID-19 will likely be as important as finding effective antiviral therapies to control COVID-19 infection and reduce life-threatening organ damage."
"Moreover, these compounds have been found to be non-toxic and non-immunosuppressive in ongoing clinical trials for other inflammatory diseases, making them even more promising candidates for rapid clinical translation," said Gilligan.
The research found that:
Increasing levels of these lipid mediators in the body could be a new therapeutic approach to preventing life-threatening inflammation caused by SARS-CoV-2.
"What is exciting for us is that these lipid mediators that 'turn off,' or resolve, inflammation are already in clinical trials for other inflammation-driven diseases, such as eye disease, periodontal disease and pain," said Dipak Panigrahy, an assistant professor of pathology in Beth Israel Deaconess Medical Center. "The mediators can quickly be applied to turn off inflammation in COVID-19 patients."
