BACKGROUND: Matrix metalloproteinases (MMPs) are responsible for the breakdown of the extracellular matrix and play an important role in the inflammatory processes of pleural exudates. The imbalance between MMPs and their inhibitors (TIMPs) is present in various pathological processes. OBJECTIVE: To evaluate the profile of MMPs and TIMPs in pleural effusions of different etiologies correlated with inflammatory markers. METHODS: The patients with pleural effusion due to tuberculosis (TB), cancer (CA) or transudate were prospectively evaluated...

Urinothorax, the presence of urine in the pleural space, is a rare cause of pleural effusion, usually associated with obstructive uropathy, or urinary trauma. We present the case of a 3 year-old boy and a systematic review of the literature of the 44 cases encountered. After resection of a Wilm's tumour in the right kidney our patient presented acute respiratory distress associated with radiographically confirmed pleural effusion. With the initial diagnosis of pneumonia or malignant pleural effusion, a closed thoracotomy was performed...

Crimean-Congo Hemorrhagic Fever (CCHF) is a disease transmitted by the Crimean-Congo hemorrhagic fever virus (CCHFV), characterized by severe fever and hemorrhage and with a reported fatality level of 3-30%. Cerebral hemorrhage, gastrointestinal hemorrhage, severe anemia, shock, myocardial infarction, pulmonary edema, and pleural effusion may be seen as causes of death. Cardiac troponin T (cTn-T) is a biochemical marker with high sensitivity and specificity in myocardial injury. The purpose of this study was to determine the prognostic significance of serum troponin T levels in CCHF patients...

BACKGROUND: The biochemical analysis of pericardial fluid for differentiating transudate from exudate is often ordered and interpreted according to the criteria extrapolated from pleural effusions. However, the validity of this discrimination when applied to pericardial effusion is under question. METHODS: Patients who underwent pericardiocentesis between January 2004 and February 2014 were identified. Among them, 216 had essential medical records available and constituted the study population...

REASONS FOR PERFORMING STUDY: Pleural effusion (PE) is reported to occur most commonly secondary to bacterial pneumonia or lung abscesses, with neoplastic effusions contributing the minority of cases. The majority of these reports originate from America and Australia, where long distance transport of horses, a recognised risk factor, appears to occur more frequently. Anecdotally, neoplastic PE is more commonly diagnosed in the UK. OBJECTIVES: To describe the causes of PE in horses resident in the UK, and to identify potential markers that can help differentiate between infectious and neoplastic causes of PE...

REVIEW
Lara Milevoj Kopcinovic, Jelena Culej
The pathological accumulation of serous fluids in the pleural, peritoneal and pericardial space occurs in a variety of conditions. Since patient management depends on right and timely diagnosis, biochemical analysis of extravascular body fluids is considered a valuable tool in the patient management process. The biochemical evaluation of serous fluids includes the determination of gross appearance, differentiation of transudative from exudative effusions and additional specific biochemical testing to assess the effusion etiology...

Asbestosis shows peribronchiolar fibrosis with numerous asbestos bodies. Subpleural dots and curvilinear lines in HRCT are good indicators for the diagnosis of asbestosis. Asbestos-related lung cancer in Japanese Compensation System means lung cancer with asbestosis. Furthermore, pleural plaques and the content of asbestos bodies in the lung tissues with the term of occupational asbestos exposure are good indicators. Mesothelioma induced also by the low dense exposure to asbestos. For the definite diagnosis of mesothelioma, we need histological examination using biopsy and immunochemical staining for positive and negative markers...

In this study, we measured ADA and DPP-IV enzymatic activity and sCD26 concentration in 150 pleural effusion (PE) samples and tested for correlations between these and other cellular and biochemical measures. We found that DPP-IV in particular might improve the specificity (but not the sensitivity) of the ADA test for diagnosis of pulmonary tuberculosis, since half of the false ADA positive results in non-tuberculous PE were also DPP-IV positive. A percentage of patients with malignant PE were sCD26 or DPP-IV positive; however, some patients with benign PE also tested positive...

BACKGROUND: Apolipoprotein E (apoE) levels have been shown to be elevated in pleural effusion of patients with non-small cell lung cancer (NSCLC). However, the diagnostic value of apoE in pleural effusion in NSCLC has not been well validated and established. METHODS: Samples of malignant pleural effusions (MPE) and benign effusions were collected and analyzed for apoE, tumor markers, and other biochemical changes. RESULTS: ApoE levels were significantly higher in MPE (n=160) than in benign pleural effusions (n=40)...

Hyaluronic acid (HA) has been proposed as a biochemical marker of malignant pleural mesothelioma (MPM). The present study focused on the implications of HA and CD44 interaction in the proliferation and invasiveness of MPM. The proliferation and invasive activity was evaluated in two human mesothelioma cell lines, ACC-MESO-1 and K921MSO, by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and the transwell chamber model. The knockdown of CD44 gene expression was accomplished by transfection of the cells with small interfering RNA...

Cell state is often assayed through measurement of biochemical and biophysical markers. Although biochemical markers have been widely used, intrinsic biophysical markers, such as the ability to mechanically deform under a load, are advantageous in that they do not require costly labeling or sample preparation. However, current techniques that assay cell mechanical properties have had limited adoption in clinical and cell biology research applications. Here, we demonstrate an automated microfluidic technology capable of probing single-cell deformability at approximately 2,000 cells/s...
