Review Meta Analysis
Statins for the prevention and treatment of acute lung injury and acute respiratory distress syndrome: a systematic review and meta-analysis.
The purpose of this meta-analysis was to assess whether statins could reduce the morbidity of acute lung injury and acute respiratory distress syndrome (ALI/ARDS) in high-risk patients and improve the clinical outcomes of patients with ALI/ARDS. Studies were obtained from PubMed, Medline, Embase and Cochrane Central Register of Controlled Trials. Randomized controlled trials (RCTs) and cohort studies, which reported morbidity, mortality, ventilator-free days, length of stay in intensive care unit and hospital or oxygenation index, were included in our meta-analysis. ⋯ Moreover, no significant difference was observed in ventilator-free days, length of stay in intensive care unit as well as hospital and oxygenation index. This meta-analysis suggests that statins neither provide benefit for lowering the morbidity of ALI/ARDS in high-risk patients nor improve the clinical outcomes of ALI/ARDS patients. Hence, it may not be appropriate to advocate statin use for the prevention and treatment of ALI/ARDS.
