Abstract
To investigate the predictive effects of neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) on renal-replacement therapy for traumatic acute kidney injury (TAKI). The urinary NGAL and KIM-1 levels of TAKI patients underwent renal-replacement therapy were assessed. The correlation and predictive model were also analyzed. Short-term (28 days) survival rate of patients were 54.5%. As TAKI stage increased, urinary KIM-1 and NGAL level increased significantly ( P < 0.05). The urinary KIM-1 and NGAL level, negatively correlated with 28-day survial, were all higher in deceased patients than survival patients ( P < 0.05). The Youden index demonstrated the predictive value of urinary NGAL area under the curve (AUC; 0.830) and KIM-1 AUC (0.879) levels in the prognosis of patients in this study. NGAL and KIM-1 can predict the prognosis of patients with TAKI and have significant correlation with the prognosis of patients.
