IL6 and COVID-19: While recent work has shown that cytokine levels in severe case of COVID‐19 are lower than those associated with ARDS unrelated to COVID‐19, sepsis and chimeric antigen receptor (CAR) T‐cell induced cytokine release syndrome, elevated levels of a number of inflammatory markers, particularly IL6, in severe cases of COVID‐19 are found to predict the need for mechanical ventilation.155, 156, 157
