ABSTRACT
ObjectiveTo assess the significance of serum cysteine proteinase inhibitor C (Cys-C) and β2 microglobulin (β2MG) concentrations in the diagnosis and prognosis of sepsis-induced acute kidney injury.Methods Two hundred and fifty patients presenting to the Emergency Department of Beijing Chaoyang Hospital from October 2008 to October 2009 with sepsis were assessed.Serum creatinine (SCr),β2MG and Cys-C concentrations and Acute Physiology and Chronic Health Evaluation Ⅱ ( APACHE Ⅱ ) scores were determined when the septic patients presented to the hospital. The 28-day mortality was recorded.The study patients were retrospectively divided into acute kidney injury ( n =63 ) and no acute kidney injury groups (n =187 ).The predictive accuracies of Cys-C and β2MG for acute kidney injury were analyzed by plotting a relative operating characteristic (ROC) curve.The Spearman interclass correlation method was used to analyze the correlation between Cys-C concentration and APACHE Ⅱ score in sepsisinduced acute kidney injury.ResultsCys-C and β2 MG concentrations were significantly greater in the acute than in the no acute kidney injury group [ ( 1189 ± 214) μg/L vs.(678 ± 118) μg/L,P =0.007 ; (3705 ±599)μg/L vs.(2365 ±446) μg/L,P =0.004,respectively].SCr concentrations and APACHE Ⅱ scores were significantly greater in the acute than in the no acute kidney injury group [ (145 ±49) vs.(73 ±25),P=0.013,(19 ±4) vs.(13 ±4),P=0.016].There was a significant correlation between Cys-C concentration and APACHEII score in the acute kidney injury group (P <0.01).The 28-day mortality was significantly greater in the acute than in the no acute kidney injury group.The areas under the ROC curve for Cys-C and β2MG concentrations were 0.909 ( OR =1.006,95% CI =1.002 - 1.009) and 0.82 ( OR =1.001,95% CI =1.000 -1.001),respectively.ConclusionsMonitoring of Cys-C and β2MG concentrations can effectively predict the occurrence of acute kidney injury in septic patients.Cys-C concentration is a more accurate predictor of this diagnosis than β2MG concentration.An increasing Cys-C concentration is an indicator of poor prognosis.
