Abstract:
Objective:To compare the early diagnostic value of the indicators of endothelial injury, renal injury, inflammation and coagulation in patients with sepsis-induced acute kidney injury (AKI).Methods:A retrospective study was performed on 119 patients with sepsis from February 2017 to March 2018. Lab tests were performed on patients at admission, which included:ing soluble thrombomodulin (sTM), tissue plasminogen activators and inhibitors (t-PAI-C), antithrombin III (AT-III), thrombin-antithrombin (TAT) complex, plasmin-alpha 2, plasmin inhibitor complex (PIC), fibrin degradation product (FDP), fibrinogen (FIB), D-Dimer, prothrombin time (PT), prothrombin time international normalized ratio (PT-INR), procalcitoni (PCT), white blood cell (WBC), neutrophil (Neu), and platelet count (PLT). The receiver-operating characteristic curve was used to analyze the predictive value of the above indicators, and logistic regression analysis was used to analyze the risk factors of sepsis-induced AKI. A prospective study was conducted from April 2018 to September 2018 and 46 patients were enrolled. The lab tests results retrieved including sTM, t-PAI-C, FDP, AT-III, TAT, PIC, FIB, D-Dimer, PT, PCT, serum cystatin C (Cys C), urine albumin (microalbumin) and albumin to creatinine ratio (ACR), urinary neutrophil gelatinase-associated lipocalin (uNGAL), urinary N-acetyl-beta-glucosaminidase (uNAG), and urinary retinol-binding protein (uRBP). As same with the previous group, the receiver-operating characteristic curve was used to analyze the diagnostic value of the above indicators, and logistic regression Was used to analyze the risk factors of sepsis-induced AKI.Results:(1) In the retrospective study: sTM, D-Dimer, PCT, PT, and PT-INR were statistically different. sTM, D-Dimer, PCT, PT, and PT-INR had a good diagnostic value for septis-induced AKI, among which, sTM had a highest diagnostic value (AUC: 0.857; 95% CI: 0.790, 0.924), better sensitivity (64.4%) and specificity (91.8%). The high expression of sTM and history of chronic kidney disease were independent risk factors for septis-induced AKI.(2) In the prospective study: PCT, sTM , Cys C, and uNGAL were statistically different. PCT, sTM, Cys C, uNGAL showed good predictive features for septis-induced AKI. sTM had the highest sensitivity (>0.999) while uNGAL had the highest specificity (0.800). The high expression of sTM was an independent risk factor for septis-induced AKI. Conclusions:sTM and uNGAL represent endothelial injury and renal tubular injury respectively. sTM is an independent risk factor of sepsis-induced AKI.
