The findings verify the outcomes of an earlier trial, which has already led to steroids getting used broadly for Covid sufferers in intensive care.
The brand new outcomes, published in JAMA, present eight lives can be saved for each 100 sufferers handled.
The researchers mentioned the findings had been spectacular, however confused steroids weren’t a coronavirus treatment.
In June, the UK’s Recovery trial discovered the primary drug – a steroid referred to as dexamethasone – that might save the lives of individuals with extreme Covid.
The most recent examine brings collectively all scientific trials involving steroids on coronavirus sufferers all over the world.
It confirms dexamethasone works and that one other steroid, hydrocortisone, is equally efficient.
“In the beginning of the yr, at instances it felt nearly hopeless figuring out that we had no particular therapies,” mentioned Prof Anthony Gordon, from Imperial School London.
“It was a really worrying time, but lower than six months later we have discovered clear, dependable proof in prime quality scientific trials of how we will deal with this devastating illness.”
The outcomes on 1,703 critically unwell sufferers confirmed:
- 40% died when given solely normal therapy
- 32% died when given steroids
The research had been on solely the sickest hospital sufferers. Most individuals get better having solely skilled delicate signs.

It’s this stage of Covid that steroids are thought to assist with.
“On the level at which you attain for an oxygen cylinder for a affected person with Covid, you most likely must be reaching for the prescription for corticosteroids,” mentioned Prof Martin Landray, from the College of Oxford.
“These outcomes are immediately useable; they’re broadly obtainable, low-cost, well-understood medicine that cut back mortality.”
Medical doctors are already utilizing dexamethasone after the outcomes earlier within the yr, however the hope is that having the selection of various medicine will improve entry to the therapy all over the world.
The medicine can both be swallowed as tablets or given through intravenous drip.
The analysis to this point has centered on low doses of steroids. There isn’t any proof that increased doses can be more practical.
New pointers for medical doctors are anticipated to be launched by the World Well being Group.
