Tuberculous Pleural Effusion (tuberculous + pleural_effusion)
Selected AbstractsClinical spectrum of tuberculous pleural effusion in childrenPEDIATRICS INTERNATIONAL, Issue 3 2007CHIH-YUNG CHIU Abstract Background: The aim of this study was to describe the clinical characteristics and potentially diagnostic specimens of pediatric patients with tuberculous pleural effusion (TPE) to make a prompt diagnosis. Methods: Children who had TPE from September 1997 to December 2003 were retrospectively reviewed at a tertiary pediatric facility in northern Taiwan. Results: There were seven boys and six girls and their ages ranged from 10 to 17 years (average, 14.6 years). Tuberculosis contact history was identified in only six patients (46%). Fever (12/92%), cough (9/69%) and malaise (6/46%) were the most common symptoms. Normal leukocyte count was found in 12 patients (92%). Chest radiograph review showed unilateral pleural effusion in 12 patients (92%) but parenchymal involvement was found in nine patients (69%). Most of the pleural fluid analysis showed a lymphocytic exudative effusion (5/6). The acid-fast bacilli (AFB) stain of sputum, gastric washing, and pleural aspirate was positive in six of 11 (55%), two of seven (29%), and one of five (20%) patients, respectively. Culture of sputum, gastric washing, and pleural aspirate yielded Mycobacterium tuberculosis in four of 11 (36%), two of seven (29%), and two of five (40%) patients, respectively. A total of 6 to 9 months of multiple-drug therapy for tuberculosis was successful without sequale. Conclusions: Tuberculous pleural effusion usually presents as an acute illness and should always be considered in the differential diagnosis for older children and adolescents with pneumonia. A normal leukocyte count with a lymphocytic exudative effusion may provide a clue to the correct diagnosis of TPE. Diagnostic specimen of sputum seems more effective and sensitive in childhood TPE, especially those having pulmonary involvement.

CELIK Summary It is suggested that leptin may be involved in inflammation. Although relation between leptin levels and active pulmonary tuberculosis has been studied, there is no information about relation between leptin levels and tuberculous pleural effusions (TPE). We evaluated the diagnostic value of pleural fluid and serum leptin levels in TPE and compared them with adenosine deaminase (ADA). Forty-five patients, 17 tuberculous effusion and 28 nontuberculous effusion, with exudative pleural effusions were included. Leptin and ADA levels were measured from serum and pleural fluid in all patients. There were no statistically significant differences between tuberculous and nontuberculous groups with respect to the serum ADA activity and pleural fluid/serum leptin ratio. On the contrary, pleural fluid leptin level, pleural fluid ADA activity, serum leptin level and pleural fluid/serum ADA activity ratio were statistically different between tuberculous and nontuberculous groups. When leptin levels were corrected for body mass index, serum leptin levels did not reach statistical significance. Cut-off points to predict tuberculosis were calculated as 9.85 ng/ml and 35.55 U/l for pleural fluid leptin level and pleural fluid ADA activity, respectively. Sensitivity, specificity and area under the curve ± standard error were 82.4%, 82.1%, 0.83 ± 0.07 for pleural fluid leptin levels and 100%, 100%, 1.00 ± 0.00 for pleural fluid ADA activity, respectively; the difference between these curves was significant (p = 0.01). Pleural fluid leptin levels were lower in tuberculous effusions than in other exudates. Pleural fluid leptin has a diagnostic value for TPE but not as good as that of ADA. [source] | ||||||||||
