Clinica Chimica Acta:血清人附睾蛋白4浓度与肺结核患者病情严重程度相关?

2020-04-12 MedSci原创 MedSci原创

人附睾蛋白4 (HE4)在各种疾病中均有升高,因此被认为是一种潜在的生物标志物。本研究的目的是评价血清HE4在肺结核(PTB)中的价值。

人附睾蛋白4 (HE4)在各种疾病中均有升高,因此被认为是一种潜在的生物标志物。本研究的目的是评价血清HE4在肺结核(PTB)中的价值。

采用化学发光微粒子免疫分析法测定127例肺结核、88例慢性支气管炎(CHB)和105例健康对照者的血清HE4浓度。采用受试者工作特征曲线(Receiver operating characteristic, ROC)和Spearman相关分析来探讨HE4的价值。

与CHB(50.2 pmol/L,IQR 42.3-64.3,P = 0.0002)和正常对照组(35.4 pmol/L,IQR 31.1-42.9,P <0.0001)相比,PTB(62.8 pmol/L,IQR 45.8-90.7)的血清HE4浓度显著升高。ROC曲线提示,用于鉴别PTB与CHB的HE4的AUC为0.647(95%CI,0.574-0.719),其切分值、灵敏度、特异性、PPV和NPV分别为71.9pmol/L、0.417、0.852、0.672和0.543。同时,与轻度至中度PTB相比,晚期PTB中HE4水平显著升高(75.8 vs. 57.7 pmol/L,P = 0.0052)。更重要的是,PTB中HE4的水平与白蛋白、CRP、空腔率显著相关(r=-0.2996,P=0.0006,r=0.265,P=0.0026,r=0.4699,P<0.0001)。

研究结果表明,血清HE4浓度升高可作为诊断和评估PTB疾病严重程度的生物标志物。
