目的探讨血清降钙素原(PCT)、高敏C反应蛋白(hs-CRP)在革兰氏阴性菌感染的腹膜透析相关性腹膜炎(PDAP)中的临床应用价值。方法回顾性分析2017年12月至2023年8月广东省佛山市南海区人民医院收治的165例腹膜透析患者的临床资料,根据培养结果将其分为革兰氏阴性菌组和非革兰氏阴性菌组;比较两组一般资料及实验室检查指标;采用多因素logistic回归分析革兰氏阴性菌感染PDAP发生的影响因素;受试者操作特征(ROC)曲线评价PCT、hs-CRP对革兰氏阴性菌感染PDAP的预测价值。结果165例腹膜透析患者共发生268例次PDAP,其中革兰氏阳性菌127例次、革兰氏阴性菌69例次、真菌5例次、分枝杆菌1例次、混合感染11例次、未找到病原菌55例次。两组PCT、hs-CRP、中性粒细胞与淋巴细胞比值及估算肾小球滤过率比较,差异有统计学意义(P<0.05)。多重共线性分析显示,方差膨胀因子均<10,提示各自变量间不存在多重共线性。多因素logistic回归分析显示,PCT(OR=1.085,95%CI:1.038~1.134,P<0.001)、hs-CRP(OR=1.008,95%CI:1.003~1.013,P=0.003)是革兰氏阴性菌感染PDAP发生的独立影响因素。ROC曲线分析显示,PCT联合hs-CRP对革兰氏阴性菌感染PDAP的诊断预测价值高于各项单独预测。结论PCT、hs-CRP是革兰氏阴性菌感染PDAP发生的独立影响因素,PCT联合hs-CRP对革兰氏阴性菌致PDAP具有较高预测价值。
