Abstract Background Acute kidney injury (AKI) can be caused by multiple factors/events, including acute coronary syndrome (ACS). Ceramides are involved in atherosclerosis progression, cardiovascular events, and renal damage. Almost no studies have been conducted on the relationship between ceramide concentrations and AKI events. Therefore, we evaluated the association between plasma ceramide level at admission and AKI in patients with ACS undergoing percutaneous coronary intervention. Methods We enrolled 842 ACS patients from the Prospective Multicenter Study for Early Evaluation of Acute Chest Pain. AKI was defined using the criteria from the 2012 Kidney Disease: Improving Global Outcomes. Eleven C16–C26 ceramides were measured using the high-performance liquid chromatography interfaced to tandem mass spectrometer procedure. Logistic regression models were used to evaluate relationships between ceramides and AKI risk. The area under the receiver operating characteristic curves (AUC) was used to evaluate differences between ceramides. Results Overall, 139 (16.5%) patients developed AKI during hospitalisation. Patients who developed AKI had higher levels of Cer(d18:1/16:0), Cer(d18:1/18:0), Cer(d18:1/20:0), Cer(d18:1/21:0), Cer(d18:1/24:1), and Cer(d18:1/24:2) than patients who did not (P < 0.05). In risk-factor adjusted logistic regression models, these ceramides were independently associated with AKI risk (P < 0.05). Cer(d18:1/24:2) had the highest odds ratio of 3.503 (Q4 vs. Q1, 95% confidence interval: 1.743–7.040, P < 0.001). Ceramides had AUCs of 0.581–0.661 (P < 0.001) for AKI. Each ceramide combined with the Mehran risk score (AUC: 0.780) had AUCs of 0.802–0.808, greater than the Mehran risk score alone. Conclusion Long-chain and very-long-chain ceramide levels may help determine the high AKI risk beyond traditional assessments.
