Plasma Monocyte Chemotactic Protein-1 Is Associated With Acute Kidney Injury and Death After Cardiac Operations.

ABSTRACT: BACKGROUND:Monocyte chemotactic protein-1 (MCP-1; chemokine C-C ligand-2 [CCL-2]) is upregulated in ischemia-reperfusion injury and is a promising biomarker of inflammation in cardiac operations. METHODS:We measured preoperative and postoperative plasma MCP-1 levels in adults undergoing cardiac operations to evaluate the association of perioperative MCP-1 levels with acute kidney injury (AKI) and death in Translational Research Investigating Biomarker Endpoints in AKI (TRIBE-AKI), a prospective, multicenter, observational cohort. RESULTS:Of the 972 participants in the study, AKI developed in 329 (34%), and severe AKI developed in 45 (5%). During a median follow-up of 2.9 years (interquartile range, 2.2 to 3.5 years), 119 participants (12%) died. MCP-1 levels were significantly higher in those who developed AKI and died than in those without AKI and death. Participants with a preoperative MCP-1 level in the highest tertile (>196 pg/mL) had an increased AKI risk than those in the lowest tertile (<147 pg/mL; odds ratio [OR], 1.43l; 95% confidence interval [CI], 1.00 to 2.05). The association appeared similar but was not significant for the severe AKI outcome (OR, 1.48; 95% CI, 0.62 to 3.54). Compared with participants with preoperative MCP-1 level in the lowest tertile, those in the highest tertile had higher adjusted risk of death (hazard ratio, 1.82; 95% CI, 1.40 to 2.38). Similarly, participants in the highest tertile had a higher adjusted risk of death (hazard ratio, 1.95; 95% CI, 1.09-3.49) than those with a postoperative MCP-1 level in the lowest tertile. CONCLUSIONS:Higher plasma MCP-1 is associated with increased AKI and risk of death after cardiac operations. MCP-1 could be used as a biomarker to identify high-risk patients for potential AKI prevention strategies in the setting of cardiac operations.

Project description:Plasma neutrophil gelatinase-associated lipocalin (NGAL) is reportedly useful for post-cardiac surgery acute kidney injury (AKI). Although chronic kidney disease (CKD) is a strong risk factor for AKI development, no clinical evaluation of plasma NGAL has specifically examined AKI occurring in patients with CKD. This study evaluated plasma NGAL in AKI superimposed on CKD after cardiac surgery.This study prospectively evaluated 146 adult patients with scheduled cardiac surgery at 2 general hospitals. Plasma NGAL was measured before surgery, at ICU arrival after surgery (0 hours), and 2, 4, 12, 24, 36, and 60 hours after ICU arrival.Based on the Kidney Disease Improving Global Outcomes (KDIGO) CKD guideline, 72 (49.3%) were diagnosed as having CKD. Of 146 patients, 53 (36.3%) developed AKI after surgery. Multiple logistic regression analysis revealed that preoperative plasma NGAL, estimated glomerular filtration rate (eGFR), and operation time are significantly associated with AKI occurrence after surgery. Plasma NGAL in AKI measured after surgery was significantly higher than in non-AKI irrespective of CKD complication. However, transient decrease of plasma NGAL at 0 to 4 hours was observed especially in AKI superimposed on CKD. Plasma NGAL peaked earlier than serum creatinine and at the same time in mild AKI and AKI superimposed on CKD with increased preoperative plasma NGAL (>300 ng/ml). Although AKI superimposed on CKD showed the highest plasma NGAL levels after surgery, plasma NGAL alone was insufficient to discriminate de novo AKI from CKD without AKI after surgery. Receiver operating characteristics analysis revealed different cutoff values of AKI for CKD and non-CKD patients.Results show the distinct features of plasma NGAL in AKI superimposed on CKD after cardiac surgery: 1) increased preoperative plasma NGAL is an independent risk factor for post-cardiac surgery AKI; 2) plasma NGAL showed an earlier peak than serum creatinine did, indicating that plasma NGAL can predict the recovery of AKI earlier; 3) different cutoff values of post-operative plasma NGAL are necessary to detect AKI superimposed on CKD distinctly from de novo AKI. Further investigation is necessary to confirm these findings because this study examined a small number of patients.
