Use of dexamethasone as prophylactic treatment in moderate to severe COVID-19 condition
A Short Review Recommended To Carry Further Research The study proposed was aimed to identify and assess the effect of dexamethasone in mild and moderate cases of COVID-19. Coronavirus disease 2019 (COVID-19) is associated with diffuse lung damage, which was declared a pandemic by WHO. Corticosteroids may modulate immune-mediated lung injury and reducing progression to respiratory failure and death. The Randomised Evaluation of COVID-19 therapy (RECOVERY) trial is a randomized, controlled, open-label, adaptive, platform trial comparing a range of possible treatments with usual care in patients hospitalized with COVID-19. The method used was to compare dexamethasone six mg given once daily for up to ten days vs. usual care alone. The primary outcome was 28-day mortality. 2104 patients randomly allocated to receive dexamethasone were compared with 4321 patients concurrently allocated to usual care. Overall results showed that 454 (21.6%) patients allocated dexamethasone and 1065 (24.6%) patients allocated usual care did within 28 days. Dexamethasone reduced deaths by one-third in patients receiving invasive mechanical ventilation, by one-fifth in patients receiving oxygen without invasive mechanical ventilation, but did not reduce mortality in patients not receiving respiratory support at randomization. Hence, In patients hospitalized with COVID-19, dexamethasone reduced 28-day mortality among those receiving invasive mechanical ventilation or oxygen at randomization, but not among patients not receiving respiratory support.
