Abstract:
Objective The aim of this study was to evaluate the value of pleural effusion heparin-binding protein ( HBP) in differential diagnosis of parapneumonic effusion .Methods Case-control study. The pleural effusion of 189 patients with pleural effusion admitted to Quzhou People's Hospital from February to July 2018, including parapneumonic effusion (n=72), tuberculous pleural effusion (n=24), cases of malignant pleural effusion ( n=46 ) and transudative pleural effusion ( n=47 ) were collected.Routine analysis,lactate dehydrogenase(LDH),adenosine deaminase (ADA) and total protein(TP)examination of all pleural effusions were performed .The levels of heparin-binding protein in the patients'pleural fluid were measured by ELISA.The difference in the overall level of each group was determined by One-way ANOVA or LSD test followed by Kruskal-Wallis H test dependence on the homogeneity of variances .The categorical data was analyzed by chi-square test.Receiver operating characteristic ( ROC) curve was plotted to evaluate the diagnostic value of heparin-binding protein for parapneumonic effusion . Results The concentration of heparin-binding protein was low in malignant pleural effusion [15.2(8.4, 33.3) ng/ml] and transudative effusion[14.1(6.5, 23.0)ng/ml], but high in parapneumonic effusion[316.1(99.5,399.8)ng/ml]and tuberculous pleurisy [64.7 (18.6, 96.8) ng/ml] .The heparin-binding protein level in parapneumonic effusion was significantly different from the other three groups (H=120.3,P<0.05).The receiver operating characteristic curve analysis for an optimal discrimination between parapneumonic effusion from non -parapneumonic effusion could be performed at a cut-off point of 64.2 ng/ml with area under the curve of 0.953[sensitivity:88.9％(64/72), specificity:89.7％(105/117),positive predictive value:84.2％(64/76), negative predictive value:92.9％(105/113)].Conclusions Heparin-binding proteinin pleural fluid is effective to be used to classify parapneumonic effusion samples .The detection of heparin-binding protein in pleural effusion has good sensitivity and specificity .It could be a biomarker for differential diagnosis of parapneumonic effusion .
