Role of C-C chemokines in the determination of pleural effusion etiology
open access
Abstract
Material and methods: Based on Light’s criteria in 29 cases exudates and in 10 transudates were recognized. We investigated 39 patients with pleural effusion (congestive heart failure - 10, parapneumonic - 11, tuberculous - 6, malignant - 12). The C-C chemokines MCP-1 and MIP-1α levels in pleural effusion and serum were measured by ELISA.
Results: The MCP-1 was significantly higher (p = 0.009) in the patient with exudates than in patients with transudates (2436 pg/ml and 794 pg/ml respectively). ROC curve analysis revealed however that this parameter has limited value in the differentiation of exudates an transudates (MCP-1 cut off value 1060 pg/ml, sensitivity 48%, specificity 90%, PPV 93%, NPV 37%). The chemokine MIP-1α were significantly higher (p = 0.001) in tuberculous than in the malignant effusion (405 pg/ml and 30 pg/ml respectively). Based on the ROC curve analysis, as a cut off value in the differentiation of tuberculous and malignant pleural effusion a value 120 pg/ml was accepted. The sensitivity of this test was 66% and specificity 99%, PPV 80%, NPV 84%.
Conclusions: The chemokine MCP-1 has a limited value in the differentiation between transudate and exudates; MIP-1α could be helpful in the differentiation between tuberculous and malignant pleural effusion.
