Corticosteroids in the adjunctive therapy of community-acquired pneumonia: an appraisal of recent meta-analyses of clinical trials.

ABSTRACT: Improving the outcome of patients with community-acquired pneumonia (CAP) is an ongoing challenge, even in the setting of significant advances in antimicrobial chemotherapy and critical care. Recognition of the underlying involvement of inflammation-mediated organ dysfunction as a determinant of adverse outcomes in CAP has aroused intense interest in the protective potential of adjunctive anti-inflammatory therapies in CAP, particularly the role of corticosteroids (CS). This is the primary topic of the current review which is focused on an evaluation of the latest meta-analyses encompassing both recent and earlier clinical trials, with particular emphasis on the stringent meta-analysis undertaken by Siemieniuk and colleagues (Ann Intern Med 2015;163:519-528). The review highlights the findings and recommendations of these and related published commentaries/critiques, while providing a brief description of those sub-groups of patients who seemingly stand to benefit most from CS therapy. This is preceded by an overview of the mechanisms of the anti-inflammatory activities of CS, the interactions of these agents with macrolide antibiotics, and the potential benefits and risks of short-term administration of CS, concluding with a succinct appraisal of priority issues for ongoing and future research.
