Effect of Rosuvastatin on Acute Kidney Injury in Sepsis-Associated Acute Respiratory Distress Syndrome.
Published Web Locationhttps://doi.org/10.1177/2054358118789158
BackgroundAcute kidney injury (AKI) commonly occurs in patients with sepsis and acute respiratory distress syndrome (ARDS).
ObjectiveTo investigate whether statin treatment is protective against AKI in sepsis-associated ARDS.
DesignSecondary analysis of data from Statins for Acutely Injured Lungs in Sepsis (SAILS), a randomized controlled trial that tested the impact of rosuvastatin therapy on mortality in patients with sepsis-associated ARDS.
Setting44 hospitals in the National Heart, Lung, and Blood Institute ARDS Clinical Trials Network.
Patients644 of 745 participants in SAILS who had available baseline serum creatinine data and who were not on chronic dialysis.
MeasurementsOur primary outcome was AKI defined using the Kidney Disease Improving Global Outcomes creatinine criteria. Randomization to rosuvastatin vs placebo was the primary predictor. Additional covariates include demographics, ARDS etiology, and severity of illness.
MethodsWe used multivariable logistic regression to analyze AKI outcomes in 511 individuals without AKI at randomization, and 93 with stage 1 AKI at randomization.
ResultsAmong individuals without AKI at randomization, rosuvastatin treatment did not change the risk of AKI (adjusted odds ratio: 0.99, 95% confidence interval [CI]: 0.67-1.44). Among those with preexisting stage 1 AKI, rosuvastatin treatment was associated with an increased risk of worsening AKI (adjusted odds ratio: 3.06, 95% CI: 1.14-8.22). When serum creatinine was adjusted for cumulative fluid balance among those with preexisting stage 1 AKI, rosuvastatin was no longer associated worsening AKI (adjusted odds ratio: 1.85, 95% CI: 0.70-4.84).
LimitationsSample size, lack of urine output data, and prehospitalization baseline creatinine.
ConclusionTreatment with rosuvastatin in patients with sepsis-associated ARDS did not protect against de novo AKI or worsening of preexisting AKI.
