摘要 目的探讨白细胞酯酶检测在腹水细菌感染快速鉴别诊断中的意义。方法采用尿液分析用的试纸条,检测了93份腹水样本中的白细胞酯酶,并分析其结果与常规、生化和细菌培养检查的相关性。结果白细胞酯酶的检出率为35.5%(33/93)。在细菌培养阳性和阴性样本中,白细胞酯酶的检出率分别为100.0%(20/20)和17.8%(13/73),两者间差异有显著性(P<0.01)。白细胞酯酶的阳性结果与腹水中多形核白细胞数量、总蛋白含量和乳酸脱氢酶水平的显著升高,以及葡萄糖的显著降低存在统计学上的相关性。当以腹水中多形核白细胞数量为腹膜炎的诊断标准时,白细胞酯酶检测的特异性与细菌培养接近(95.0%vs100.0%),但敏感性却显著高于细菌培养(90.9%vs60.6%,P<0.01)。结论检测腹水中的白细胞酯酶能敏感、特异、简便和快速地帮助确定腹膜炎的诊断,并能提示腹水中是否存在细菌感染,因此值得在临床上广泛开展。
