When I asked about a dozen ED docs, internists, ID specialists and intensivists whether or not they used steroids for community acquired pneumonia, I did not receive one definitive clear answer. But when I asked them whether or not they would use steroids for COVID pneumonia, they all clearly and definitively said a resounding “yes” (and most of them added that it was the only drug besides oxygen that was effective for COVID pneumonia). So this got me thinking – what are the indications for steroids in patients with pneumonia besides those with concurrent COPD exacerbations, ARDS or adrenal shock? This is Journal Jam – so, the other question is: what is the evidence for benefit for steroids in CAP, the flu and COVID pneumonia? And if there is benefit, do those benefits outweigh the potential harms? To help us sort this out, Justin and Anton have the mighty return of a special guest – Dr. Andrew Morris in this Journal Jam podcast…
Steroids are thought to curb the inflammatory response in CAP, improve symptoms, reduce the frequency of acute respiratory distress syndrome, and decrease the length of illness.

Initial steroid dosing options for CAP and COVID pneumonia in the ED include
Dexamethasone 6-20mg IV
Methylprednisolone 40mg IV
Hydrocortisone 50-200mg IV
Take home points on steroids for community acquired pneumonia, influenza and COVID pneumonia
Steroids do not offer benefit in patients with confirmed influenza pneumonia, mild bacterial community acquired pneumonia or COVID pneumonia patients who do not require supplemental oxygen
There is a signal of benefit for the sickest bacterial pneumonia patients heading for the ICU, although there is no clear data on the timing of those steroids – so the decision to give steroids may be left to the ICU (unless there is a long delay to admission from the ED)
A meta-analysis is only as good as the studies that it includes; in the case of CAP, the Cochrane meta-analysis claiming benefit of steroids included studies that were either small with poor methodology or adequately sized but without significant benefit for patient-oriented outcomes
The 4 trials reviewed here looked at steroids in COVID pneumonia; taken together, there is some evidence to suggest that steroids may benefit COVID pneumonia patients who require supplemental oxygen to maintain an oxygen saturation >90%.
RECOVERY trial – dexamethasone 6mg daily (max 10 days) showed an overall statistically significant mortality benefit, with the largest benefit in those patients requiring mechanical ventilation who had symptoms for at least 7 days, and a non-statistically significant increase in mortality in those patients who did not require supplemental oxygen
CoDEX trial – dexamethasone 20mg IV daily x 5 days, then 10mg IV daily x 5 days in ICU showed more ventilator-free days, SOFA score was significantly lower in the dexamethasone group at 7 days suggesting lower organ dysfunction in the dexamethasone group; however, there was no significant difference in all-cause mortality at 28 days
CAPE COVID trial – hydrocortisone 200mg/day x 7 days, then 100mg/day x 4 days, then 50mg/day for 3 days showed no statistically significant difference in treatment failure on day 21, defined as death or persistent dependency on mechanical ventilation or high-flow oxygen therapy; hydrocortisone did not significantly reduce the proportion of patients receiving mechanical ventilation on day 21 and did not increase in the rate of secondary infections
REMAP-CAP trial – ICU patients in shock given hydrocortisone 50mg IV q6h x 7 days showed no statistically significant difference in respiratory and cardiovascular organ support-free days, up to day 21.
Update 2022:A meta-analysis of 16 RCTs including 3,842 hospitalized patients with community acquired pneumonia found no difference in all cause, in hospital mortality with corticosteroid therapy (RR 0.85, 95% CI 0.67 – 1.07), but was associated with a reduction in progression to mechanical ventilation (RR 0.51, 95% CI 0.33 – 0.77). Steroid use was also associated with subsequent readmission (RR 1.20, 95% CI 1.05 – 1.38). Abstract
