Intravenous contrast induced acute kidney injury prevention with high doses of statins

Abstract

Aim. The aim of our study was to assess the frequency of contrast-induced acute kidney injury (CI-AKI) in patients undergoing computed tomography (CT) with intravenous contrast media and to evaluate the effects of statins in the prevention of CI-AKI. Materials and methods. 181 patients undergoing CT with intravenous contrast media administration were included in prospective observational study (ClinicalTrials.gov ID NCT04666389). The primary endpoint was CI-AKI according to KDIGO criteria (the 25 % rise (or 0,5 mg/dl) of serum creatinine from baseline assessed 48–72 hours after administration of contrast media). There were 120 patients in the group with high dose of statins administration and 60 patients without statin treatment. The most frequent cardiovascular disease was hypertension in both groups — 93 % and 85 % respectively. Results. CI-AKI was diagnosed in 12 (6,7 %) patients — 9 patients in the no statins group and 3 patients in the statins group. The high dose statin administration statistically significant had less frequency of CI-AKI (p = 0,003) compare with no statins group (OR = 0,144, 95 %CI: 0,037–0,554). Conclusion. Statin pretreatment is effective at preventing CI-AKI and should be considered in high-risk patients.
