Association between EASIX and acute kidney injury in critically ill cancer patients.

Background: To analyze the relationship between endothelial activation and stress index (EASIX) and the occurrence of acute kidney injury (AKI) in critically ill cancer patients.

Methods: Critically ill cancer patients were selected from the Medical Information Mart for Intensive Care IV (MIMIC-IV). Multivariate logistic regression was used to analyze the association between EASIX and the occurrence of AKI in critically ill cancer patients.

Results: One thousand forty-one cancer patients were retrospectively included, including 607 men and 434 women with mean age of 64.86 ± 13.67 years. Univariate analysis showed that high EASIX levels were associated with an increased risk of AKI occurrence in intensive care unit (ICU) cancer patients (OR: 1.47,95% CI: 1.13-1.91, P < 0.05). After adjusting for other confounders, high EASIX levels remained an independent risk factor predicting the development of AKI (OR: 1.42,95% CI: 1.08-1.88, P < 0.05). Trends in effect sizes were generally consistent across all subgroups in the prespecified subgroup analyses.

Conclusion: EASIX is an independent risk factor for AKI in critically ill cancer patients. More prospective studies are needed to validate the effect of EASIX on the occurrence of AKI in critically ill cancer patients in the future.
