Coronavirus: What is the

Sudden acute respiratory failure and a sharp deterioration in the health of some patients with Covid-19 have often been attributed by doctors around the world (and in Greece) to an overreaction of the immune system, which causes the so-called “cytokine storm”. “, Which in turn leads to lung damage.

But new data presented by American scientists seem to call this theory into question.

Researchers at the University of Washington School of Medicine and St Jude Children’s Hospital studied 71 patients with severe Covid-19 compared with 26 patients with acute influenza and made the relevant re-publication in medRxiv (not yet published). reported that only 4% of patients developed extreme inflammation and a true “cytokine storm.”

In contrast, they said, according to Reuters, most patients had increased cytokines, but at lower levels than in typical influenza cases. This, they argue, shows rather repression than an overreaction of the immune system.

Dr. Kenneth Remy of the University of Washington noted that the administration of anti-inflammatory drugs to patients with Covid-19 may actually worsen their condition, further “inhibiting” their immune system and thus reducing coronary heart disease. easily.
