【摘要】：目的探讨血降钙素原(procalcitonin,PCT)和中性粒细胞比例(percentage of neutrophils,Neu%)对肝病自发性细菌性腹膜炎(spontaneous bacterial peritonitis,SBP)的诊断价值。方法回顾性分析2014年1月至2016年12月在西南医院感染科住院且入院后同时检测PCT、血常规、腹水常规和腹水培养的130例肝病腹水患者临床资料,SBP确诊组89例,其中培养阳性且多形核细胞(polyremorphonuclear,PMN)≥250×10~6/L患者10例(SBP1组),培养阳性但PMN250×10~6/L患者11例(SBP2组),培养阴性但PMN≥250×10~6/L患者68例(SBP3组);非感染性腹水组41例。比较4组患者入院时的血PCT、Neu%、腹水PMN等指标。通过受试者工作曲线(ROC)评价PCT、Neu%对SBP的诊断价值及效能。结果 PMN≥250×10~6/L的SBP患者培养阳性率为12.8%。PCT在培养阳性的腹水患者中显著高于培养阴性的患者[中位数(四分位距)]:[4.51(1.54,8.46)vs 0.77(0.21,1.69),P0.05]。通过ROC曲线分析,PCT诊断SBP1、SBP2、SBP3的最佳界值分别为:0.795、0.265、0.405 ng/m L;AUC值依次为:0.963、0.767、0.714;敏感度依次为:100.00%、90.00%、62.30%;特异度依次为:92.70%、63.40%、80.50%;血常规Neu%诊断的最佳界值分别为:68.45%、62.65%、65.00%;AUC值依次为:0.878、0.756、0.669。依据上述界值,降钙素原和中性粒细胞比例两者串联诊断SBP1、SBP2、SBP3的AUC值依次为:0.976、0.865、0.706。结论血降钙素原和血常规中性粒细胞比例在SBP中均具有一定的预警效果和诊断价值,不同类型SBP其CUT-OFF值不同,临床可根据实际情况综合分析。
[Abstract]:Objective to evaluate the diagnostic value of serum procalcitonin (procalcitonin,PCT) and neutrophil ratio (percentage of neutrophils,Neu%) in the diagnosis of spontaneous bacterial peritonitis (spontaneous bacterial peritonitis,SBP) in liver diseases. Methods the clinical data of 130 patients with liver and ascites from January 2014 to December 2016 were analyzed retrospectively, including PCT, blood routine examination, ascitic fluid routine test and ascites culture. 89 patients were diagnosed as SBP group. Among them, 10 cases (SBP1 group) were cultured positive and polymorphic cells (polyremorphonuclear,PMN) 鈮，
