Abstract EN
Objective.
As cell-free DNA levels in the pleural fluid and serum of parapneumonic pleural effusion (PPE) patients have not been thoroughly explored, we evaluated their diagnostic potential.
Methods.
Twenty-two PPE and 16 non-PPE patients were evaluated.
Serum and pleural fluids were collected, and cell-free DNA was quantified.
All biomarkers were assessed for correlation with days after admission.
Receiver operating characteristic (ROC) curve analysis was used to determine diagnostic accuracy and optimal cut-off point.
Results.
Nuclear and mitochondrial DNA levels in the pleural fluid and nuclear DNA levels in serum of PPE patients were significantly higher than in those of the non-PPE patients.
However, only cell-free DNA levels in pleural fluid correlated with days after admission among PPE patients (r= 0.464, 0.538, respectively).
ROC curve analysis showed that nuclear and mitochondrial DNA in pleural fluid had AUCs of 0.945 and 0.889, respectively.
With cut-off values of 134.9 and 17.8 ng/ml for nuclear and mitochondrial DNA in pleural fluid, respectively, 96% sensitivity and 81% specificity were observed for PPE diagnosis.
Conclusion.
Nuclear and mitochondrial DNA in pleural fluid possess PPE diagnostic potential and correlated with disease severity.
Serum nuclear DNA could also be used to distinguish freshly admitted PPE patients (Day 1) from non-PPE patients, but with less accuracy.
