Statins in pneumonia - magic versus science?

Abstract

Several studies have investigated the use of statins as an adjunct in the treatment of pneumonia, some with conflicting conclusions. The most recent of these large observational studies again suggests statin use is associated with an improved outcome for patients with pneumonia. How best to incorporate these findings into current practice is of great interest. Hidden confounders plague database interrogation and so cast doubt on the real or causal nature of observed associations. Data from large, observational studies must be complemented by smaller biological studies and randomised controlled trials in an effort to complete missing pieces in the biological puzzle of the use of statins in patients with pneumonia. © 2012 BioMed Central Ltd.
