Abstract:
Objective To investigate the clinical value of serum cystatin C (sCysC) and APACHE Ⅱ score in predicting diagosis and prognosis of acute kidney injury(AKI) in patients with sepsis. Methods In this study, we prospectively enrolled 138 adult patients with sepsis who had been admitted to the mixed ICU of Xiaolan Hospital of Southern Medical University during March 2015 to January 2016. According to the Kidney Disease Improving Global Outcomes (KDIGO) criterion, the patients were divided into non-AKI group and AKI group (including mild AKI and severe AKI). The receiver operating characteristic(ROC) curve and the area under curve(AUC) were used to evaluate these indexes' capability of detecting septic AKI and its prognosis. Results In this study,72 patients (52.2％) developed AKI. The levels of sCysC and APACHE Ⅱ score were significantly higher in AKI than in non-AKI (P<0.05). In total, 33 patients (23.9％) developed severe AKI. The levels of sCysC and APACHE Ⅱscore were significantly higher in severe AKI than in non-AKI and mild AKI (P<0.05) . Combination of sCysC and APACHE Ⅱ score predicted AKI and severe AKI after ICU admission with a higherAUC value (0.880&0.930) than each biomarker alone. In this cohort, in-hospital mortality was 19.6％and renal replacement therapy rate was 9.4％,which were strikingly higher in AKI group than non AKI group (P<0.05). Conclusions sCysC is a novel indexes for predicting AKI and its prognosis in patients with sepsis. Combinating with APACHE Ⅱ score can further improve its predictive performance of AKI detection and short-term prognosis.
