Article in the NY Times today [1].
Seems that if dexy is given before the body goes into mutual destruction mode - i.e. the cytokine storm - it can increase mortality risk. Makes perfect sense. We want to stimulate the immune system until the last moment & dampen it thereafter. (This was discussed in an earlier thread.) But how to recognize that moment.
"The primary symptoms of a cytokine storm are high fever, swelling and redness, extreme fatigue and nausea." [2]
Dexy cannot be used to protect against infection or progression (au contraire mon frère). It should be used when the above symptoms occur. For those without Covid-19 lung issues who are isolating at home, the switch can happen fast. It's an emergency situation.
