New insights on inflammation in COVID-19

Severe cases of COVID-19 can involve extensive inflammation in the body, and clinicians have wondered if this state is similar to what are called cytokine storm syndromes, in which the immune system produces too many inflammatory signals that can sometimes lead to organ failure and death. A new study published in Arthritis & Rheumatology indicates that different markers in the blood clearly differentiate excessive inflammation in critical COVID-19 from cytokine storm syndromes.
