%X Acute kidney injury (AKI) is the most common and critical complication in patients with acute myocardial infarction (AMI). This study aims to evaluate the significance of elevated soluble interleukin 2 receptor (sIL-2R) levels in predicting AKI and mortality.
A total of 446 patients with AMI were enrolled between January 2020 and July 2022, including 58 patients with AKI and 388 without AKI. The sIL-2R levels were measured using a commercially available chemiluminescence enzyme immunoassay. Logistic regression analysis was used to examine the risk factors for AKI. Discrimination was assessed based on the area under the receiver operating characteristic curve. The model was internally validated using 10-fold cross-validation.
During hospitalization, 13% of patients developed AKI following AMI, with higher sIL-2R levels (0.61 ± 0.27 U/L vs. 0.42 ± 0.19 U/L, p = 0.003) and in-hospital all-cause mortality (12.1% vs. 2.6%, P < 0.001). The sIL-2R levels emerged as an independent risk factor for both AKI (OR = 5.08, 95% CI (1.04-24.84, p < 0.045) and in-hospital all-cause mortality (OR = 73.57,95% CI 10.24-528.41, p < 0.001) in AMI patients. The sIL-2R levels were found to be useful biomarkers in prediction of AKI and in-hospital all-cause mortality in patients with AMI (AUC: 0.771 and 0.894, respectively). The respective cutoff values for sIL-2R levels in predicting AKI and in-hospital all-cause mortality were determined to be 0.423 U/L and 0.615 U/L.
The level of sIL-2R was an independent risk factor and predictor for both AKI and in-hospital all-cause mortality in patients with AMI. These findings highlight the potential of sIL-2R as a valuable tool for identifying high-risk patients regarding AKI and in-hospital mortality.
