BACKGROUND: Differential diagnosis between malignant pleural effusion (MPE) and benign pleural effusion (BPE) remains a clinical challenge. OBJECTIVE: The aim of the study is to assess the efficacy of the serum and pleural fluid (PF) miRNA panels in distinguishing MPE from BPE. METHODS: Fourteen candidate miRNAs which were shown aberrant expression in lung cancer based on previous studies were tested by quantitative real-time PCR (qRT-PCR) in 20 MPE patients and 20 BPE patients. Significantly aberrantly expressed miRNAs were further assessed by qRT-PCR in all patients enrolled in this study. A receiver operating characteristic (ROC) curve was constructed, and the area under the ROC curve (AUC) was calculated to evaluated the diagnostic performance of the miRNAs. RESULTS: miR-21, miR-29c and miR-182 were found to be significantly aberrantly expressed in the serum and PF of MPE patients. The AUCs for the combination of miR-21, miR-29c and miR-182 in serum and PF were 0.832 and 0.89 respectively in distinguishing MPE from infection-associated PE including tuberculous pleurisy and parapneumonia PE, and 0.866 and 0.919 respectively for differentiating MPE from heart failure-associated PE, which were superior to AUC of each individual miRNAs. CONCLUSIONS: miR-21, miR-29c and miR-182 in serum and PF could be useful biomarkers for MPE of diagnosis.

Abstract Background Malignant pleural effusion (MPE) is a common complication of lung cancer and intrathoracic spreading or metastasis of extra-thoracic malignancy. The aim of the present study was to evaluate the levels of pro-cathepsin D from plasma and pleural fluid in patients with MPE and those in patients with benign pleural effusion (BPE) including pleural tuberculosis and parapneumonic effusion.Methods This study included 81 patients with pleural effusion who underwent thoracentesis and pleural biopsy. Pleural fluid and serum were collected as a standard procedure for all individuals at the same time. The level of pro-cathepsin D was measured by the sandwich enzyme-linked immunosorbent assay method.Results Though there were no significant differences in plasma pro-cathepsin D between the two groups, the level of pleural fluid pro-cathepsin D was significantly higher in the MPE group than the BPE group (0.651 versus 0.590 pg/mL, P = 0.034) (Table 1). In addition, there were no differences in pleural fluid pro-cathepsin D level according to causative malignancy of MPE. On receiver operating characteristic curve analysis, the optimal discrimination point between the MPE group and BPE group was defined as a cut-off value of 0.5960 pg/mL for pleural fluid pro-cathepsin D (81.0% sensitivity; 53.0% specificity) and 0.4335 pg/mL for plasma pro-cathepsin D (71.4% sensitivity; 61.7% specificity).Conclusions We found that the level of pleural fluid pro-cathepsin D was significantly higher in the MPE group than the BPE group. Pro-cathepsin D could be a novel and potential biomarker to discriminate MPE from BPE.

Abstract The significance of carbohydrate (cancer) antigen 125 (Ca-125) and carcinoembryonic antigen (CEA) tumour markers levels in differential diagnostics of malignant and benign pleural effusion was studied. Within this prospective study, 121 patients with fluids of various aetiology in the pleural cavity were analysed. Malignant pleural effusion was detected in 55 patients, parapneumonic effusion in 28 patients, transudative effusion of cardiac origin in 31 patients, pancreatitis in one patient and tuberculous pleurisy in five patients. The highest accuracy in diagnosis of malignancy was observed for Ca-125 and CEA levels in the pleural fluid: 75.2% at cut-off value ≥1452 U/mL and 76.9% at cut-off value ≥6.58 ng/mL, respectively. We conclude that the level of tumour markers in pleural fluid has additional diagnostic significance in the differential diagnosis of malignant and benign pleural effusions.

Abstract Introduction: To accurate differential diagnosis of pleural effusion (PE) is still a big challenge. Gasdermin D (GSDMD), controlling pyroptosis in cells, has multiple physiological functions. The diagnostic role of GSDMD in PE remains unknown.Methods: Sandwich ELISA kits that we developed were applied to measure the level of GSDMD for 335 patients with the definite cause of PE, including transudative pleural effusion, tuberculous pleural effusion (TPE), parapneumonic pleural effusion (PPE), and malignant pleural effusion (MPE). Clinical follow up of 40 cases of PPE were conducted and divided into efficacy group and non-efficacy group according to therapeutic outcome. The receiver operating characteristic (ROC) curve was conducted to explore the diagnostic and predictive performance of GSDMD. Nucleated cells (NCs) in pleural effusion were isolated and further infected with bacteria to verify the cell source of GSDMD.Results: In this study, there was prominent statistical significance among the concentration of GSDMD in these four groups (all p < 0.0001, except between MPE and PPE). ROC curve indicated that GSDMD can be an efficient biomarker for differential diagnosis of transudative pleural effusion and other groups (all AUC ＞ 0.973). Noteworthily, the highest AUC belonged to tuberculosis diagnosis of 0.990, and the sensitivity and specificity were 100% and 97.53%. The combination of GSDMD, adenosine deaminase (ADA) and lactate dehydrogenase (LDH) will further improve the diagnostic efficiency especially between TPE and PPE (AUC = 0.968). The AUC of GSDMD change at day 4 could predict the therapeutic effect at an early stage was 0.945 (P < 0.0001). Interestingly, bacterial infection experiments further confirm that the pleural fluid GSDMD was expressed and secreted mainly by the NCs. Conclusion: GSDMD and its combination not only candidate as the potentially novel biomarkers to separate PEs early and effectively, but also monitor disease progression.

The aim is to examine whether the changes in pleural fluid interleukin (IL)-1β, IL-2, IL-6, and IL-8 levels were significant in differential diagnosis of childhood pleural effusions. IL-1β, IL-2, IL-6, and IL-8 levels in pleural fluids of all 36 patients were measured. The levels of IL-1β, IL-2, IL-6, and IL-8 in pleural fluids were statistically significantly higher in the transudate group compared with those of the exudate group. The levels of IL-1β, IL-6, and IL-8 were also found to be statistically significantly higher in the empyema group compared with both the parapneumonic and the tuberculous pleural effusion groups. The levels of IL-2 and IL-6 were detected to be statistically significantly higher in the tuberculous pleural effusion group in comparison with those of the parapneumonic effusion group. The results showed that pleural fluids IL-1β, IL-2, IL-6, and IL-8 could be used in pleural fluids exudate and transudate distinction.

Concentration of zinc in blood serum and effusion was determined in 104 patients with the pleural effusion of different etiology. The importance of zinc concentration in serum and effusion was analyzed, as well as their relation regarding the differential diagnosis of pleural effusion. It was established that the isolated zinc concentrations in serum and pleural effusion could not be used separately either in differing transudates from exudates or in the diagnosis of the pleural diseases. The average value of zinc in the pleural effusion in relation to the serum value in patients with tuberculosis effusion was 1.37, higher than 1 in all patients and was significantly different from the average value of the ratio 0,74 in patients with nonspecific and malignant pleural effusions. The relation of zinc concentration in the effusion and serum higher than 1.0 reliably indicated the presence of tuberculous pleurisy.

Abstract Objective This study aimed to establish a predictive model based on the clinical manifestations and laboratory findings in pleural fluid of patients with pleural effusion for the differential diagnosis of malignant pleural effusion (MPE) and tuberculous pleural effusion (TPE). Methods Clinical data and laboratory indices of pleural fluid were collected from patients with malignant pleural effusion and tuberculous pleural effusion in Zigong First People's Hospital between January 2019 and June 2020，and were compared between the two groups. Independent risk factors or Independent protective factors for malignant pleural effusion were investigated using multivariable logistic regression analysis. Receiver operating characteristic curve (ROC) analysis was performed to assess the diagnostic performance of factors with independent effects, and combined diagnostic models were established based on two or more factors with independence effect. ROC curve was used to evaluate the diagnostic ability of each model, and the fit of the eath model was measured using Hosmer-Lemeshow goodness-of-fit test. Results Patients with MPE were older than those with TPE, the rate of fever of patients with MPE was lower than that of patients with TPE, and these differences were statistically significant (p < 0.05). Carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), cytokeratin-19 fragment antigen (CYFRA21-1), cancer antigen 125 (CA125), and glucose (GLU) levels in the pleural fluid were higher, but total protein (TP), albumin (ALB) and Adenosine deaminase (ADA) levels in the pleural fluid were lower in MPE patients than in TPE patients, and the differences were statistically significant (P<0.05). In multivariate logistic regression analysis, CEA and NSE levels in the pleural fluid were independent risk factors for MPE, whereas ADA levels in pleural fluid and fever were independent protective factors for MPE. The differential diagnostic value of pleural fluid CEA and pleural fluid ADA for MPE and TPE were higher than that of pleural fluid NSE（p<0.05） and the area under the ROC curve was 0.901, 0.892, and 0.601, respectively. Four different binary logistic diagnostic models were established based on pleural fluid CEA combined with pleural fluid NSE, pleural fluid ADA or ( and ) fever. Among them, the model established with the combination of pleural fluid CEA and pleural fluid ADA (logit (P) = 0.513 + 0.457*CEA-0.101*ADA) had the highest diagnostic value for malignant pleural effusion, and its predictive accuracy was high with an area under the ROC curve of 0.968 [95% confidence interval (0.947, 0.988)]. But the diagnostic efficacy of the diagnostic model could not be improved by adding pleural fluid NSE and fever. Conclusion The model established with the combination of CEA and ADA in the pleural fluid has a high differential diagnostic value for malignant pleural effusion and tuberculous pleural effusion, and NSE in the pleural fluid and fever cannot improve the diagnostic efficacy of the diagnostic model.

Abstract Background Prostate cancer is one of common cancers around the world, and in our country the incidence and mortality of PCa are both increasing. More and more reports have revealed that SOX9 is involved in various human cancers. In this study, we aimed to explore the relationship between SOX9 expression and diagnostic value of PCa patients. Methods In this study, quantitative real-time PCR (qRT-PCR) was performed to determine the expression of SOX9 of the 131 PCa patients and 74 healthy volunteers. And receiver operating characteristic (ROC) curve was used to determine the diagnostic value of SOX9 for PCa patients. Results The results of qRT-PCR showed that the expression of serum SOX9 in PCa patients was higher than that in healthy controls (P < 0.05). And the expression of SOX9 was significantly associated with PSA (P = 0.001), differentiation (P = 0.000), and lymph node metastasis (P = 0.000). Besides, the area under the ROC curve (AUC) was 0.966 with the sensitivity of 93.2% and specificity of 87.8% respectively. The optimal cutoff value of SOX9 was 2.34. Conclusions Our results found that SOX9 is a novel oncogene for PCa, and may be a novel and effective biomarker for the diagnosis of patients with PCa.

Abstract Background There have been many studies on the clinical characteristics of neutrophilic, lymphocytic, and/or eosinophilic pleural effusion. While caring for patients with pleural effusion, we found that histiocytic pleural effusion (HisPE) was not uncommon. However, few studies have explored HisPE. The purpose of the present study was to determine the clinical characteristics and etiologies of HisPE. Methods In this retrospective study, HisPE was defined as pleural fluid white blood cells comprised of ≥ 50% histiocytes. Using a clinical data warehouse, patients with HisPE among all patients aged > 18 years who underwent thoracentesis and pleural fluid analysis between January 2010 and December 2019 at Ulsan University Hospital were enrolled. A total of 295 (9.0%) of 3279 patients who underwent thoracentesis were identified as HisPE patients. Among them, 201 with exudative HisPE were included. Clinical characteristics and etiologies were extracted from medical records and analyzed. Results Among the 201 patients with exudative HisPE, the major causes were malignant pleural effusion (n = 102 [50.7%]), parapneumonic effusion (n = 9 [4.5%]), and tuberculous pleurisy (n = 9 [4.5%]). In the 102 patients with malignant pleural effusion, the main types of cancer were lung (n = 42 [41.2%]), breast (n = 16 [15.7%]), and stomach cancer (n = 11 [10.8%]). Among lung cancers, adenocarcinoma (n = 34 [81.0%]) was the most common histology. Conclusions The leading cause of exudative HisPE was malignancy, particularly lung cancer. Physicians should consider the possibility of malignant disease if histiocytes are predominantly present in pleural effusion.

Cholesterol and carcinoembryonic antigen (CEA) levels in pleural effusion and sera, were measured in 199 patients with pleural effusions of various origins. Malignant cause was found in 93, and nonmalignant in 106 patients. Mean cholesterol level in sera of patient with malignant disease was 5.0 ? 0.93mmol/L, and in nonmalignant group 4.34 ? 1.32 mmol/L. The difference was not statistically significant. Mean cholesterol level in nonmalignant pleural effusions was higher thAn those in malignant (2.51 ? 1.23 mmol/L; and 2.28 ? 1.06 mmol/L), but the difference was also not significant. Average pleural fluid/serum cholesterol ratio (HolI/S) in nonmalignant group was 0.61 ? 0.32 and in malignant group 0.46 ? 0.22. The difference between those mean values was significant. Higher ratio, at the cut off value of 0.5 was found in 79/106 and in 25/93 malignant patients. Calculated sensitivity was 75%, specificity 73%, positive predictive value 76%, negative predictive value 65% and accuracy 69%. Significant negative correlation between Holi/S and pleural fluid CEA was found (p<0.05). It was assumed that pleural fluid/serum cholesterol ratio lower than 0,5 could be of great benefit, as an additional test in the differentiation of malignant from benign pleural effusion.
