Selvi, A. Kant, S. Arslan, M. Ozgel. Background: Residual pleural thickening (RPT) still occurs in most patients with tuberculosis pleurisy despite advances in the treatment of tuberculosis. The aim of this study was to evaluate the significance of RPT in tuberculosis pleurisy with the patients clinical findings, biochemical and microbiological properties of pleural effusion and with the total adenosine deaminase (ADA) and isoenzymes levels. Methods: 121 tuberculosis pleurisy patients were evaluated retrospectively. According to posteroanterior chest x-rays, the 63 (52%) cases with the thickness 2 mm or more in lower lateral hemithorax were grouped as I and the 58 (48%) cases without pleural thickness were grouped as II. The amount of pleural effusion was classified into small, medium or massive according to their chest x-rays. In both groups; sex, age, symptoms score, bacteriological and biochemical tests and ADA levels were recorded. Results: 81 (67%) male and 40 (33%) female, overall 121 patients were enrolled into the study. RPT was found higher in males (p=0.014) and the increase ran parallel with the amount of cigarette smoking (p=0.014). RPT was found to be lower in small effusions (p=0.001). The group with RPT, the serum albumin was found lower (p=0.002), pleural fluid total protein (p=0.047) and the ratio of pleural fluid protein to serum protein (p=0.002) were found higher. In group I, total ADA: 69.5±38.9 IU/L and ADA2: 41.3±31.6 IU/L were higher than the cases without RPT (p=0.032, p=0.017, respectively). Conclusions: We suggest that the immunological mechanisms are effective in the development of pleural thickening.

Exudative Pleural Effusion

Pleural effusion discusses the radiographic and computed tomography (CT) manifestations of this entity. Pleural effusion is classified based on pleural fluid analysis using Light’s criteria: transudative and exudative. Free pleural fluid collects in the most dependent aspect of the pleural space due to gravitational effects. It exhibits a meniscus configuration on upright chest radiography. Pleural effusion in a supine or semiupright patient is more difficult to identify but may be suspected in cases with a homogeneous or gradient-like opacity over the lower hemithorax, elevation of the hemidiaphragm contour, or an apical cap. Subpulmonic pleural effusion manifests with lateral displacement of the apex of the ipsilateral hemidiaphragm contour and increased distance between the gastric air bubble and pseudodiaphragmatic contour. Exudative pleural effusion should be suspected in cases with CT findings of pleural thickening, enhancement, septations, and/or loculations.

Background: C-reactive protein in both pleural fluid and serum has been found to be higher in tubercular pleural effusion than in other causes of pleural effusion. Objectives: The main aim of this study was to find out the diagnostic value of C-reactive protein in patients withlymphocytic pleural effusion. Methodology: A cross-sectional study was conducted in 90 patients with pleural effusion who underwent thoracocentesis at Kathmandu Medical College Teaching Hospital, Kathmandu, Nepal. The complete biochemical tests of pleural fluid and serum were performed. The C-reactive protein concentrations of both pleural fluid and serum were then measured from samples from patients with lymphocytic exudative pleural effusion. Results: Ninety patients with exudative lymphocytic pleural effusion were included. Male patients were 56 (62.2%) and female were 34 (37.8%) with the male to female ratio of 1.64. Mean age of the patients was 51±21.54 (Mean ± Standard Deviation). The pleural fluid C-reactive protein levels in tubercular pleural effusion were higher (48.87±24.19 mg/dl) compared to non-tubercular group (38.30±17 mg/dl; p<0.001). Similarly, the serum fluid C-reactive protein levels in tubercular pleural effusion were higher (29.60±13mg/dl) compared to non-tubercular group (18.14±9.2mg/dl; p< 0.001). The sensitivity of pleural fluid C-reactive protein level in diagnosing tubercular pleural effusion was 86%. Conclusion: Simple and inexpensive test like C-reactive protein is useful in the diagnostic workup of lymphocytic pleural effusions. High C-reactive protein levels are very suggestive of tubercular pleural effusion.

Adenosine Deaminase (ADA) is used as a well established biological marker for diagnosis of tuberculous pleuritis. The aim of this study was to assess the sensitivity and specificity of ADA in patients with pleural effusion admitted in the medical ward. This was an cross sectional study. The information was gathered only from those patients whose pleural fluid sample was sent for ADA in clinical biochemistry laboratory of KIST Medical College and Teaching hospital. The data was acquired from the medical records of patients attending medical ward. The patients were considered as TB positive if they were clini­cally diagnosed so and taken as negative otherwise. Fifty six pleuritis patients were evaluated. Using the cut off value of 30 U/L, the overall sensitivity and specificity was 93.3% and 57.1% respectively. The association between ADA findings and the clinical findings were statistically significant (p <0.001). The positive predictive value (PVP) and the negative predictive value (PVN) were 82.3% and 80% respectively. ADA is an inexpensive, rapid and simple test for analysis of tuberculous pleuritis. Though, it is a sensitive test for tuberculosis, due to its low specificity, sometimes negative cases can be considered as positive.

Pleural effusion is an abnormal accumulation of fluid in the pleural space resulting from increased production of fluid or decreased resorption of fluid in the pleural space. Pleural effusion can be caused by infectious diseases, malignancies, collagen disease, gastrointestinal disease, heart disease and other causes such as medication. Adenosine Deaminase (ADA) is an enzyme involved in the catabolism of purines. This enzyme can be measured in pleural fluid, serum and other body fluids such as cerebrospinal and ascites fluid. The aim of this study was to analyze the correlation between adenosine deaminase activity in pleural fluid and serum in patients with pleural effusion. This research was an observational study with a cross-sectional design. Examination of ADA activity was performed in pleural fluid and serum. Adenosine deaminase activity was examined using photometric methods (Non-Giusti), using Diazyme reagent by TMS 24i Premium. Subjects were 46 patients with pleural effusion caused by malignancies, tuberculosis and systemic diseases. Mean±SD ADA activity for all pleural effusion samples in serum was 13.037± 8.365 (0.5-34.1) U//L and pleural fluid 30.843± 28.860 U//L (1.3-140.8). No correlation between ADA activity in serum and pleural fluid (r=0.173, p= 0.252) was found in all samples. No correlation between ADA activity in serum and pleural fluis was found in malignancies (r=0.109, p=0.630), tuberculosis (r= 0.366, p=0.123), systemic diseases (r =0.466, p=0.429) and non-tuberculosis group (r=0.126, p=0.532). There was no correlation between pleural fluid ADA activity and serum.
