AbstractPatients with tuberculous pleural effusion (TPE) or malignant pleural effusions (MPE) frequently have similar pleural fluid profiles. New biomarkers for the differential diagnosis of TPE are required. We determined whether cytokine profiles in the PE of patients could aid the differential diagnosis of TPE. 30 patients with TPE, 30 patients with MPE, 14 patients with empyema (EMP) and 14 patients with parapneumonic effusion (PPE) were enrolled between Dec 2018 and 2019. The levels of interleukin (IL)-6, IL-18, IL-27, CXCL8, CCL-1 and IP-10 were determined in PE by ELISA along with measurements of adenosine deaminase (ADA). The best predictors of TPE were combined ADA.IL-27 [optimal cut-off value = 42.68 (103 U ng/l2), sensitivity 100%, specificity 98.28%], ADA [cut off value 27.5 (IU/l), sensitivity 90%, specificity 96.5%] and IL-27 [cut-off value = 2363 (pg/ml), sensitivity 96.7%, specificity 98.3%, p ≤ 0.0001]. A high level of IL-6 [cut-off value = 3260 (pg/ml), sensitivity 100%, specificity 67.2%], CXCL8 [cut-off value = 144.5 (pg/ml), sensitivity 93.3%, specificity 58.6%], CCL1 [cut-off value = 54 (pg/ml), sensitivity 100%, specificity 70.7%] and IP-10 [cut-off value = 891.9 (pg/ml), sensitivity 83.3%, specificity 48.3%] were also predictive of TPE. High ADA.IL-27, ADA and IL-27 levels differentiate between TPE and non-TPE with improved specificity and diagnostic accuracy and may be useful clinically.

Abstract Background: Tuberculous pleural effusion (TPE) is one of the most common forms of extrapulmonary tuberculosis. Patients with tuberculous or malignant pleural effusions (MPE) frequently have similar clinical manifestations and pleural fluid profile. New biomarkers for the differential diagnosis of TPE are required. Objective: We sought to determine of whether cytokine profiles in the pleural effusion of patients were suitable as tools for the differential diagnosis of TPE. Methods: 30 patients with TPE, 30 patients with MPE, 14 patients with empyema and 14 patients with parapneumonic effusion were enrolled consecutively from the Masih Daneshvari Hospital, Tehran, Iran between Dec 2018-Dec 2019. The levels of interleukin (IL)-6, IL-18, IL-27, CXCL-8, CCL-1 and IP-10 were determined in pleural effusions by ELISA along with measurements of adenosine deaminase (ADA). Results: The levels of all analytes measured except IL-18 were higher in TPE compared with non-TPE subjects (all p < 0.01). The best predictors of TPE were combined ADA.IL-27 (optimal cut-off value = 42.68 103.U.ng/L2, sensitivity 100%, specificity 98.28%, p ≤ 0.0001), ADA (optimal cut off value 27.5 IU/L, sensitivity 90%, specificity 96.5%, p ≤ 0.0001) and IL-27 (optimal cut-off value = 2363 pg/ml, sensitivity 96.7%, specificity 98.3%, p ≤ 0.0001). A high level of IL-6 (optimal cut-off value = 3260 pg/ml, sensitivity 100%, specificity 67.2%, p ≤ 0.0001), CXCL-8 (optimal cut-off value = 144.5 pg/m, sensitivity 93.3%, specificity 58.6%, p ≤ 0.0001), CCL-1 (optimal cut-off value = 54 pg/mL, sensitivity 100%, specificity 70.7%, p ≤ 0.0001) and IP-10 (optimal cut-off value = 891.9 pg/mL, sensitivity 83.3%, specificity 48.3%, p = 0.0001) were also predictive of TPE. Conclusion: High ADA.IL-27, ADA and IL-27 levels differentiate between TPE and non-TPE with improved specificity and diagnostic accuracy.

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.

Objective: To study the diagnostic accuracy of Adenosine deaminase enzyme (ADA) in the diagnosis of tuberculous pleural effusion (TPE).Material and Methods: It was a cross-sectional descriptive study conducted in the Pulmonology departments of Lady Reading and Khyber Teaching Hospital Peshawar and department of Pathology, Khyber Medical College, Peshawar from April 2015 to Jan 2016. A total of 210 tuberculous and non-tuberculous pleural effusion patients were selected through consecutive non-probability sampling techniques. After physical and systemic examination, 3cc of pleural fluid was taken. ADA was estimated by Non-Guisti and Galanti method through the simple colorimetric method. All the data was entered in a specially designed proforma and SPSS v16 was used for statistical analysis.Results: Out of 210 tuberculous and non-tuberculous pleural effusions, the commonest cause of pleural effusion was tuberculosis followed by malignancy. In our study, Pleural fluid ADA levels have sensitivity, specificity, positive predictive value( PPV), and negative predictive value (NPV) of 95.5%, 92.3%, 92.4%, and 96% respectively in differentiating tuberculous pleural effusions from non-tuberculous lymphocytes predominant pleural effusions. Conclusion: Tuberculosis is the commonest infectious disease worldwide. A pleural fluid ADA level of ≥ 35 U/L in lymphocyte-predominant effusions makes mycobacterium tuberculosis most likely etiology. This test is not only very sensitive and specific but also it is very cheap, quick, and easy to perform by routine colorimetric method.

ABSTRACT Background: Conventionally Pleural effusions are suspected by history of pleuritis, evaluated by physical signs and multiple view radiography. Trans-thoracic pleural aspiration is done and aspirated pleural fluid is considered the gold-standard for pleural effusion. Chest sonography has the advantage of having high diagnostic efficacy over radiography for the detection of pleural effusion. Furthermore, ultrasonography is free from radiation hazards, inexpensive, readily available  and feasible for use in ICU, pregnant and pediatric patients. This study aims to explore the diagnostic accuracy of trans-thoracic ultrasonography for pleural fluid detection, which is free of such disadvantages. The objective is to determine the diagnostic efficacy of trans-thoracic ultrasound for detecting pleural effusion and also to assess its suitability for being a non-invasive gold-standard.   Subject and Methods: This retrospective study of 4597 cases was conducted at pulmonology  OPD-Gulab Devi Teaching Hospital, Lahore from November 2016 to July 2018. Adult patients with clinical features suggesting pleural effusions were included while those where no suspicion of pleural effusion, patients < 14 years and pregnant ladies were excluded. Patients were subjected to chest x-ray PA and Lateral views and chest ultrasonography was done by a senior qualified radiologist in OPD. Ultrasound-guided pleural aspiration was done in OPD & fluid was sent for analysis. At least 10ml aspirated fluid was considered as diagnostic for pleural effusion. Patient files containing history, physical examination, x-ray reports, ultrasound reports, pleural aspiration notes and informed consent were retrieved, reviewed and findings were recorded in the preformed proforma. Results were tabulated and conclusion was drawn by statistical analysis. Results: Out of 4597 cases, 4498 pleural effusion were manifested on CXR and only 2547(56.62%) pleural effusions were proved by ultrasound while 2050 (45.57%) cases were reported as no Pleural effusion. Chest sonography demonstrated sensitivity, specificity, PPV, NPV and diagnostic accuracy 100 % each. Conclusions: Trans-thoracic ultrasonography revealed an excellent efficacy that is why it can be considered as non-invasive gold standard for the detection of pleural effusion.

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.

Pleural effusion is divided into exudative and transudative effusion, and the distinction between exudate and transudate requires multiple investigations of biochemical parameters and their comparison in pleural fluid and serum. This study aimed to assess the diagnostic value of CEA, CA125, and CRP and their cut-off point for discrimination of exudative pleural effusions. This epidemiological and cross-sectional study was performed on 50 patients aged between 18 to 90 years with the diagnosis of exudative pleural effusion referred to Imam Khomeini Hospital in Ahvaz in 2018 and 2019. Demographic and clinical information of patients were collected. The pleural effusion was diagnosed based on physical examination and chest radiography. Pleural effusion was confirmed by thoracentesis. A pleural fluid sample was taken from all patients, and the levels of CEA, CA125, and CRP markers were measured in the pleural fluid. Differentiation of transudate and exudate pleural effusions was performed using Light criteria. The mean CEA and CA125 level of pleural fluid were significantly higher, and the mean CRP level of pleural fluid was significantly lower in patients with malignant diagnoses (P <0.05). Cut-off value with highest sensitivity and specificity in differentiating types of exudative pleural effusions was obtained for CEA tumor marker (greater than 49.8), CA125 tumor marker (greater than 814.02), and CRP marker (less than 7.56). Also, in differentiating types of exudative pleural effusions, CEA tumor marker had sensitivity (89.03%) and specificity (78.42%); CA125 tumor marker had sensitivity (53.18%) and specificity (62.44%), and CRP marker had sensitivity (82.16%), and specificity (89.05%) were. Although the tumor markers had high specificity in the present study, the low sensitivity of some of these tumor markers reduced their diagnostic value. On the other hand, given the numerous advantages of tumor markers, such as low cost and non-invasive, combining them with another can increase the diagnostic value and accuracy.

As a tool for differentiating malignant and benign pleural effusions, we evaluated the diagnostic value of the assay of tissue polypeptide-specific antigen (TPS) in pleural fluid and serum, and of the pleural fluid TPS/serum TPS ratio in patients with pleural effusion. We studied prospectively 147 consecutive patients who had pleural effusions: 43 malignant pleural effusions and 104 benign pleural effusions. TPS levels were measured by RIA. The sensitivity and specificity of these measurements were: TPS in pleural fluid (cutoff 20,000 U/L): 0.21 and 0.98; TPS in serum (cutoff 300 U/L): 0.31 and 0.96; pleural fluid TPSI serum TPS ratio (cutoff 1200): 0.07 and 0.99. All these values enhanced the sensitivity of cytologic analysis of pleural fluid. However, we conclude that TPS assay in pleural fluid and serum, and the pleural fluid TPSI serum TPS ratio have limited diagnostic value in patients with pleural effusion.
