DANGERS OF DEXAMETHASONE: when used too soon has no effect on #COVID19 mortality if <7 days *since symptom onset*. In fact, it can weaken innate immunity. So Trump either:

A. Illness moved REALLY damn fast

B. diagnosed much earlier

C. his doctors caved to his wishes

2) As pointed out, dexamethasone used early can “shoot you in the foot” by weakening immune system. This is why we see the slightly trending upwards / null effect in those with #COVID19 and not on oxygen. https://twitter.com/sciencecohen/status/1312852480632541184

4) as mentioned also earlier, even if it does work, it’s just small 18% relative drop for those on oxygen. I.e. from 26.2% to 23.3% in the RECOVERY trial. See why it’s not a magic bullet even when used properly? https://twitter.com/drericding/status/1312794635559931906

5) that 18% drop viewed another way.

6) Furthermore, Dr Bob Wachter (chairman of medicine at UCSF) also warns that dexamethasone can make you feel better but actually might NOT make the illness actually better. It might even suppress immunity in milder patients early on, he also attests. https://twitter.com/bob_wachter/status/1312812846372151296
