A cheap steroid that can help save the lives of patients with severe
COVID-19 should be reserved for serious cases in which it has been shown
to provide benefits, the World Health Organization said on Wednesday.
WHO chief Tedros Adhanom Ghebreyesus said research was at last
providing “green shoots of hope” in treating the virus, which has killed
more than 400,000 people worldwide and infected more than 8 million.
Trial results announced on Tuesday by researchers in Britain showed
dexamethasone, a generic drug used since the 1960s to reduce
inflammation in diseases such as arthritis, cut death rates by around a
third among the most severely ill coronavirus patients admitted to
hospital.
That makes it the first drug proved to save lives in fighting the
disease. Countries are rushing to ensure that they have enough of it on
hand, although medical officials say there is no shortage.
Some doctors were cautious, citing possible side-effects and asking to see more data.
A patient in Denmark received dexamethasone on Wednesday, local news
agency Ritzau reported. The doctor who prescribed the drug said the
medical profession was well acquainted with its side-effects.
The head of the WHO’s emergencies programme, Mike Ryan, said the drug
should only be used in those serious cases where it has been shown to
help.
“It is exceptionally important in this case, that the drug is
reserved for use in severely ill and critical patients who can benefit
from this drug clearly,” he told a briefing.
Britain has increased the amount of dexamethasone it has in stock and
on order to 240,000 doses, Health Minister Matt Hancock said.
Methylprednisolone, a steroid similar to but less potent than
dexamethasone, has been used in Sweden since March, a Stockholm-based
doctor told media.
The steroid was introduced to standard practice after it proved
effective on a coronavirus patient who wasn’t showing signs of recovery
with other treatments, Lars Falk, of the New Karolinska Hospital, told
Sweden’s Dagens Nyheter.
The dexamethasone study’s results are preliminary, but the
researchers behind the trial said it suggests the drug should become
standard care in severely stricken patients.
‘NO SILVER BULLET’
For patients on ventilators, the treatment was shown to reduce
mortality by about a third, and for patients requiring only oxygen,
deaths were cut by about one fifth, according to preliminary findings
shared with the WHO.
“This is the first treatment to be shown to reduce mortality in
patients with COVID-19 requiring oxygen or ventilator support,” Tedros
said in a statement late on Tuesday.
“WHO will coordinate a meta-analysis to increase our overall
understanding of this intervention. WHO clinical guidance will be
updated to reflect how and when the drug should be used in COVID-19,”
the agency added.
South Korea’s top health official expressed caution about
dexamethasone and the European Union and Switzerland both said they were
awaiting more information.
An Italian expert said that dexamethasone was no silver bullet.
“The study showed a marginal reduction in deaths,” said Lorenzo
Dagna, immunology head at IRCCS San Raffaele Scientific Institute in
Milan. “We’re light years away from being able to say we’ve found the
cure against COVID.”
On the positive side, he added, the drug is cheap and plentiful.
As the new coronavirus has wreaked havoc on global economies, some
countries have moved quickly to authorise emergency use of medicines
only to later backtrack.
The U.S. Food and Drug Administration, for instance, withdrew
emergency authorisation for hydroxychloroquine, a malaria drug touted by
U.S. President Donald Trump and others against COVID-19, after studies
showed it did not help.
The WHO said on Wednesday that testing of hydroxychloroquine in its
large multi-country trial of treatments for COVID-19 patients had been
halted after research showed no benefit.
“We have been burned before,” Dr. Kathryn Hibbert, director of the
medical intensive care unit at Harvard’s Massachusetts General Hospital,
said, expressing caution about dexamethasone.
