This study aimed to perform a systematic review and meta-analysis of randomized controlled trials (RCTs) in order to calculate the effect size of statin therapy in changing plasma cortisol concentrations. Following a systematic search in Medline, SCOPUS, Web of Science and Google Scholar databases (by up to March 01, 2015), 7 eligible RCTs were selected. Random-effects meta-analysis suggested a significant increase in plasma cortisol concentrations following statin therapy (WMD: 6.34%, 95% CI: 1.80, 10.87, p=0.006). Subgroup analysis confirmed the significance of the effect with lipophilic statins comprising atorvastatin, simvastatin, and lovastatin (WMD: 7.00%, 95% CI: 2.21, 11.79, p=0.004) but not with hydrophilic statins (rosuvastatin and pravastatin) (WMD: 0.60%, 95% CI: -13.46, 14.66, p=0.933). In the meta-regression analysis, changes in plasma cortisol concentrations following statin therapy were found to be independent of treatment duration. Results of this meta-analysis of RCTs suggest a significant elevation in plasma cortisol levels following statin therapy.
