Application of the data to our patients
The benefit of adjuvant corticosteroids is most clear in hospitalized patients with severe CAP. Recent, strong evidence supports decreased mortality, decreased time to clinical stability, and decreased length of stay in our patient, with severe CAP, if treated with 20-60 mg of prednisone or equivalent total daily dose for 3-7 days. For patients with non-severe CAP, we suggest taking a risk-benefit approach based on other comorbidities, as the risk for CAP-related rehospitalizations may be higher.
For patients with underlying lung disease, specifically COPD or reactive airway disease, we suggest a low threshold for adding corticosteroids. This approach is more anecdotal than data driven, though corticosteroids are a mainstay of treatment for COPD exacerbations and a retrospective analysis of more than 20,000 hospitalized children with CAP and wheezing revealed decreased length of stay with corticosteroid treatment.13 Furthermore, a number of the studies described above included patients with COPD. Our threshold rises significantly in patients with poorly controlled diabetes mellitus.
Bottom line
For patients hospitalized with severe community-acquired pneumonia, recent evidence supports the use of low dose, short-course, systemic corticosteroids in addition to standard therapy.
