Diagnostic utility of LDH, CA125 and CYFRA21-1 in tuberculosis pleural effusion
1Department of Respiratory and Critical Care Medicine, Ruijin Hospital Affiliated Shanghai Jiao Tong University School of Medicine, Shanghai, China; Institute of Respiratory Diseases, School of Medicine, Shanghai Jiaotong University, Shanghai, China.
Objective:
The aim of this study was to assess the diagnostic value of several markers for tuberculosis pleural effusion (TPE) using the combined analysis of Lactate dehydrogenase (LDH), Carbohydrate antigen 125 (CA125), Cytokeratin-19 fragment (CYFRA21-1).
Methods:
From January to December in 2018, a total of 37 patients with pleural effusion (22 cases of transudative pleural effusion, 15 cases of tuberculosis pleural effusion and 22 cases of Transudative pleural effusion who were hospitalized in our hospital were reviewed. Receiver operating characteristic (ROC) curves and logistic regression equations was used to evaluate the diagnostic efficiency of each marker.
Results:
The levels of LDH and CYFRA21-1 of tuberculosis pleural effusions were obviously higher than those of transudative pleural effusion with statistically significant difference (<0.05). The areas under the ROC curve of LDH, CA125 and CYFRA21-1 were 0.92, 0.344 and 0.656, respectively. The diagnostic sensitivity of LDH, CA125 and CYFRA21-1 were 100%, 13.3%, 73.3%, respectively. The combined detection of LDH, CA125 and CYFRA21-1 were higher than those of any other combinations of the indexes.
Conclusions:
The study showed a high diagnostic sensitivity and specificity of combined speculation of LDH, ADA and CYFRA21-1 in Tuberculosis pleural effusion.
