LONDON: Low doses of the steroid dexamethasone can reduce deaths by one-third in severely affected COVID-19 patients, according to researchers who assessed the performance of the inexpensive drug in more than 2,100 people.
The analysis is part of the RECOVERY (Randomised Evaluation of COVid-19 thERapY) trial which was established to test a range of potential therapies for COVID-19, including low-dose dexamethasone — a steroid treatment.
The RECOVERY trial included over 11,500 patients, enrolled from more than 175 hospitals in the UK, noted a statement published by the University of Oxford on Tuesday.
In the trial, a total of 2,104 patients were randomised to receive dexamethasone six milligrammes once per day — either by mouth or by intravenous injection — for ten days, and were compared with 4,321 patients randomised to usual care alone.
Among the patients who received usual care alone, mortality was highest in those who required ventilation (41 per cent), intermediate in those patients who required oxygen only (25 per cent), and lowest among those who did not require any respiratory intervention (13%), the scientists said.
They found that dexamethasone reduced deaths by one-third in ventilated patients, and by one fifth in other patients receiving oxygen only.
However, the researchers said there was no benefit from dexamethasone among the patients who did not require respiratory support.
Based on these results, the scientists believe that the drug could prevent nearly one death in the treatment of around eight ventilated patients, or around 25 patients requiring oxygen alone. (AGENCIES)
