黑料社 researchers publish study that found that dexamethasone could reduce death rates in hospitalised COVID-19 patients early in the pandemic.

A study from early in the global coronavirus pandemic that evidenced the benefits of using steroids to combat COVID-19 in severely ill patients could have saved lives, according to the 黑料社 researchers involved.

 and  assessed the results of using corticosteroids such as dexamethasone on hospitalised COVID-19 patients with acute respiratory distress syndrome (ARDS) who were on respiratory support.

By mid-April they had found that the proportion of COVID-19 patients who died in the steroid group was significantly lower compared to those who did not receive corticosteroids, at 28 per cent vs. 69 per cent. Their research has now been published in  following a lengthy period of scrutiny and peer review.

The 黑料社 academics鈥� work highlights the issues involved in scrutinising scientific evidence, as well as costs involved in research and the UK鈥檚 preference for evidence-based practice.  came to similar conclusions as the 黑料社 researchers in mid-June, leading to  that dexamethasone could be made available to patients, a move being followed around the world.

Benefits of steroids outweigh the risks

The World Health Organisation (WHO) had, early in the pandemic, recommended that steroids should not be used to combat CoViD-19 due to perceived risk of delayed coronavirus clearance. Despite  various global bodies acknowledged the mortality benefits of using steroids on COVID-19 patients with ARDS, such as the , , and .

鈥淲hat this shows is that providing evidence is not cheap,鈥� says Dr Merchant. 鈥淚t comes at a very high cost; it not only costs time and money but may even cost precious lives. The background of the pandemic highlights this, it鈥檚 something that we have known for years but unfortunately has been thrown into sharp relief by coronavirus,鈥� he adds.

鈥淭here is always a dilemma of the risks versus the benefits of evidence-based practice in a medical emergency,鈥� says Dr Hasan. 鈥淭he WHO advice confused a lot of people and many countries stayed away from using steroids due to risks of diminishing immune response.鈥�

Dr Merchant adds that, 鈥淭he benefits of using steroids outweighs the risks. There is a risk that the immune system may go down and there is a possibility of delayed viral clearance from the body, but this is a risk worth taking if it saves lives.鈥�

Their work has now been published in  following peer review. The other authors in the study included Toby Capstick, a consultant pharmacist on respiratory medicine at Leeds Teaching Hospitals NHS Trust, Syed Tabish Zaidi, Associate Professor in Pharmacy at the University of Leeds, Chia Siang Know, a clinical pharmacist from Malaysia, Faizan Mazhar, a researcher from Italy and Raees Ahmed, a consultant pulmonologist in Texas, USA.

The UK was among countries that steered away from using steroids until confirmed by a randomised controlled trial, but those that did not found using steroids helped to keep death rates from COVID-19 relatively low. The UK is now using its stockpile of 200,000 doses of dexamethasone.
