Pulmonary Disorders I
Corticosteroids in COVID-19 (see the Infectious Diseases I chapter for further information)
Currently, clinical practice guidelines strongly recommend the use of dexamethasone in ICU
patients with COVID-19 (Table 5).
The landmark RECOVERY clinical trial compared dexamethasone 6 mg daily up to 10 days total
administered either orally or intravenously compared to usual care alone in 6425 hospitalized
patients with COVID-19 (N Engl J Med 2021;384:693-704). Among 1007 patients in the prespecified
subgroup analysis requiring invasive MV, the 28-day mortality rate was significantly lower in the
dexamethasone group (29.3%) than in the usual care group (41.4%) (RR 0.64; 95% CI, 0.51β0.81).
In addition, the probability of hospital discharge within 28 days among those receiving invasive
MV significantly improved in patients receiving dexamethasone over usual care (RR 1.45; 95%
CI, 1.13β1.85). Moreover, MV cessation was more likely with dexamethasone than with usual care
(RR 1.47; 95% CI, 1.20β1.78). Similarly, use of dexamethasone lowered overall mortality among
all hospitalized patients compared with usual care. However, a survival benefit was only observed
among patients with COVID-19 requiring oxygen support (both invasive and noninvasive) over
those without any respiratory support.
The CoDEX clinical trial randomized 299 adult patients with COVID-19 with moderate to
severe ARDS to either dexamethasone (20 mg intravenously daily over 5 days followed by 10 mg
16). The primary end point was ventilator-free days during the initial 28 days consisting of the
number of days alive and liberation from MV for 48 hours or more. The mean number of ventilator-
free days in the dexamethasone and usual care groups was 6.6 days and 4.0 days (adjusted difference
of 2.26 days; 95% CI, 0.2β4.38; p=0.04), respectively. No differences were observed between study
groups for secondary aims, including 28-day mortality, ICU-free days, overall MV days, or risk of
adverse events. A limitation of this trial is that it was terminated early because of the publication
of the RECOVERY trial findings. This may have introduced bias despite showing a positive benefit
associated with dexamethasone.
