BACKGROUND: Haematological malignancy is an important cause of pleural effusion. Pleural effusions secondary to haematological malignancy are usually lymphocyte predominant. However, several other conditions such as carcinoma, tuberculosis, and chronic heart failure also cause lymphocytic effusions. Lymphocyte subset (LS) analysis may be a useful test to identify haematological malignancy in patients with lymphocytic effusions. However, research into their utility in pleural effusion diagnostic algorithms has not yet been published...

A negative pressure normally exists between the visceral and parietal pleurae in the lungs, which can act as vacuum for fluid, air and small particles from different parts of the body, allowing them to move into the pleural space and be retained in it, thus resulting to different manifestations of pleural disorders. A pleural effusion is the result of fluid collection between the parietal and visceral pleural surfaces. The most common cause in developed countries is congestive heart failure, followed by pneumonia and malignancy...

In this study, we aimed to examine the clinical value of the pleural effusion (PE) biomarkers, soluble mesothelin-related peptide (SMRP), cytokeratin 19 fragment (CYFRA 21-1) and carcinoembryonic antigen (CEA), and the utility of combining chest computed tomography (CT) findings with these biomarkers, in diagnosing malignant pleural mesothelioma (MPM). We conducted a retrospective cohort study in a single center. Consecutive patients with undiagnosed pleural effusions who underwent PE analysis between September 2014 and August 2016 were reviewed...

BACKGROUND: Many centers performing medical thoracoscopy (MT) to diagnose pleural disease will insert a chest tube and admit patients to hospital after the procedure, which is inconvenient for patients and contributes to healthcare costs. We report the data on the safety, outcomes, and performance characteristics of outpatient MT with indwelling pleural catheter (IPC) insertion in a large Canadian cohort. METHODS: This retrospective cohort study reviewed patients who underwent outpatient MT and IPC insertion under conscious sedation...

BACKGROUND: Closed pleural biopsy was previously considered a procedure of choice in cases of undiagnosed pleural effusion with good efficacy. Currently, the closed pleural biopsy has been replaced by thoracoscopic biopsy but not easily available in resource-limited setups. OBJECTIVE: The objective of this study was to analyze the diagnostic yield and safety of closed needle pleural biopsy in exudative pleural effusion and assessment of patients' characteristics with the yield of pleural biopsy...

We present the case of a 43-year-old Italian woman with a left undiagnosed pleural effusion, which in subsequent months presented a clinically unexpected evolution with the appearance at first of a right wrist tenosynovitis and subsequently a bilateral lung involvement caused by M. Tuberculosis. With this case report, we would like to underline the importance of making a correct diagnosis of any pleural effusion as soon as possible by at least a thoracocentesis. If untreated, tuberculosis may easily disseminate to other organs...

The cause of pleural effusion remains uncertain in approximately 15% of patients despite exhaustive evaluation. As recently described immunoglobulin (Ig)G4-related disease is a fibroinflammatory disorder that can affect various organs, including the lungs, we investigate whether idiopathic pleural effusion includes IgG4-associated etiology. Between 2000 and 2012, we collected 830 pleural fluid samples and reviewed 35 patients with pleural effusions undiagnosed after pleural biopsy at Yamaguchi-Ube Medical Center...

BACKGROUND: Pleural fluid adenosine deaminase (pfADA) is not routinely measured in patients with undiagnosed pleural effusion due to limited evidence of its diagnostic utility in areas of low tuberculosis (TB) prevalence. METHODS: We conducted a retrospective consecutive case series analysis of all patients who underwent pfADA testing from 2009 to 2015 at a tertiary service pleural centre in south London. Using receiver operating characteristic (ROC) curve analysis, we identified the optimal threshold at which maximal sensitivity and specificity were achieved...

Vikas Pathak, Ray W Shepherd, Ehab Hussein, Rajiv Malhotra
BACKGROUND: Pleural biopsy is often obtained in patients with undiagnosed exudative pleural effusion during pleuroscopy. Standard forceps have been traditionally used for the biopsy. Cryoprobes are being increasingly used for transbronchial lung biopsy as they obtain larger specimens and have less crush artifact. However, the safety and feasibility of cryoprobe biopsy compared to standard forceps for pleural biopsy has not been fully assessed. OBJECTIVES: The objective of this study was to demonstrate the safety and feasibility of cryoprobe biopsy in the pleural space using semi-rigid pleuroscopy...

BACKGROUND: Medical thoracoscopy is an effective and safe procedure for diagnosing pleural effusions of undetermined causes. But there are still a part of patients with pleural effusions were diagnosed as nonspecific pleurisy when no specific biopsy results were found after undergoing thoracoscopic biopsy. The long-term outcome of these patients is unclear, and anxieties about undiagnosed malignancy persist. METHODS: Between July 2005 and June 2014, medical thoracoscopy using the semi-rigid instrument was performed and pleural biopsy was taken in 833 patients with pleural effusions...

INTRODUCTION: In case of undiagnosed pleural effusions, it is necessary to conduct thoracentesis with pleural fluid (PF) cytology. Yet, sensitivity of PF cytology is widely variable as a result of sample size, experience and preparation method. OBJECTIVES: The aim of this study was to assess whether pleural fluid (PF) cytology is correlated to visceral or parietal pleural invasion as assessed by thoracoscopy in metastatic pleural effusions. METHODS: All records of patients with pleural effusion were reviewed...

BACKGROUND: Bacterial pleural infection requires prompt identification to enable appropriate investigation and treatment. In contrast to commonly used biomarkers such as C-reactive protein (CRP) and white cell count (WCC), which can be raised due to non-infective inflammatory processes, procalcitonin (PCT) has been proposed as a specific biomarker of bacterial infection. The utility of PCT in this role is yet to be validated in a large prospective trial. This study aimed to identify whether serum PCT is superior to CRP and WCC in establishing the diagnosis of bacterial pleural infection...

Conventional methods may fail to identify the cause of pleural effusion (PE), thus establishing reliable biomarkers is deemed necessary. This study aimed at examining the role of vascular endothelial growth factor (VEGF) as a biomarker in the differentiation between malignant and benign PEs in adults. A comprehensive literature search in PubMed (Medline), Scopus (ELSEVIER), and Cochrane Central Register of Controlled Trials (CENTRAL) databases was conducted using keywords. We included studies that evaluated pleural and/or serum levels of VEGF among patients presenting with undiagnosed PE and the association between these levels and the final diagnosis...

BACKGROUND: Pleural effusion secondary to a nonmalignant cause can represent significant morbidity and mortality. Nonmalignant pleural effusion (NMPE) is common, with congestive heart failure representing the leading cause. Despite this, there are limited data on mortality risk and associated prognostic factors. METHODS: We recruited 782 consecutive patients presenting to a pleural service between March 2008 and March 2015 with an undiagnosed pleural effusion. Further analysis was conducted in 356 patients with NMPE...
