Study: Respiratory failure in COVID-19 usually not driven by cytokine storm
A new study from Washington University School of Medicine in St. Louis and St. Jude Children's Research Hospital in Memphis, Tenn., however, suggests that an out-of-control immune response is not the main problem for the vast majority of hospitalized COVID-19 patients. Only 4% of patients in the study had the sky-high levels of immune molecules that signify a so-called "cytokine storm." The rest had inflammation, but not a remarkably high amount for people fighting infection. If anything, the COVID-19 patients had less inflammation than a comparable group of influenza patients.
