Abstract

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). 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. 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. The study showed a high diagnostic sensitivity and specificity of combined speculation of LDH, ADA and CYFRA21-1 in Tuberculosis pleural effusion. El objetivo de este estudio fue evaluar el valor diagnóstico de diversos marcadores de derrame pleural tuberculoso (DPTB) utilizando el análisis combinado de lactato deshidrogenasa (LDH), antígeno carbohidrato 125 (CA-125) y fragmento de citoqueratina-19 (CYFRA 21-1). De enero a diciembre de 2018, revisamos un total de 37 pacientes hospitalizados en nuestro hospital con derrame pleural (22 casos de derrame pleural trasudativo y 15 casos de derrame pleural tuberculoso). Se utilizaron las curvas ROC y ecuaciones de regresión logística para evaluar la eficacia diagnóstica de cada marcador. Los niveles de LDH y CYFRA 21-1 de los pacientes con derrame pleural tuberculoso fueron obviamente superiores a los pacientes con derrame pleural trasudativo, con diferencia estadísticamente significativa (p < 0,05). Las áreas bajo la curva ROC de LDH, CA-125 y CYFRA 21-1 fueron 0,92, 0,344 y 0,656, respectivamente. La sensibilidad diagnóstica de LDH, CA-125 y CYFRA 21-1 fueron del 100, 13,3 y 73,3%, respectivamente. La detección combinada de LDH, CA-125 y CYFRA 21-1 fue superior a cualesquiera otras combinaciones de los índices. El estudio reflejó una alta sensibilidad diagnóstica y especificidad del análisis combinado de LDH, ADA y CYFRA 21-1 en el derrame pleural tuberculoso.
