Between April 1985 and July 1989, 125 cases with pleural effusion were admitted to our department. The causes of pleural effusion were carcinomatous pleurisy in 47 cases, infection without tuberculosis in 34 cases, tuberculous pleurisy in 17 cases, cardiac insufficiency and hypoproteinemia in 11 cases, trauma and pneumothorax in nine cases, collagen disease in two cases and unknown origin in five cases. Carcinomatous pleurisy and tuberculous pleurisy, the differential diagnosis of which is very important, comprised 37% and 14% of all cases, respectively. These diseases can be definitively diagnosed by pleural biopsy, effusion cytology and/or effusion culture. In July 1987, we introduced thoracoscopy to improve the ratio of definitive diagnoses. The ratio for carcinomatous pleurisy in the previous term, when thoracoscopy was not being used, was 59%, while that in the latter term, when it was used, was 73%. The ratio for all cases with tuberculous pleurisy was 47%. Prior to June 1987, pleural biopsies in our department were performed with a Cope needle. Using that procedure, a low positive ratio of 50% was obtained. For thoracoscopic pleural biopsies, a high positive ratio of 84% was achieved (in carcinomatous pleurisy, 13 out of 15 cases; in tuberculous pleurisy, three out of four cases). This procedure was performed with minimal patient discomfort and no serious complications. Therefore, thoracoscopic pleural biopsy is recommended as a diagnostic procedure for cases with pleural effusion. 相似文献

The objective of this study was to evaluate the utility of invasive and noninvasive diagnostic procedures in tuberculous pleurisy (TPE) in an area with intermediate incidence of tuberculosis. The aim was to determine the cutoff value for adenosine deaminase (ADA) and the sensitivity and specificity of ADA and evaluate pleural fluid cytology and pleural biopsy in the differential diagnosis of malignant and tuberculous pleurisy. The study included 121 patients. TPE was confirmed in 54 patients and malignant effusion in 67 patients. Criteria used for TPE diagnosis were positive cultures of effusion or biopsy specimen, tuberculous granulomas, or positive sputum cultures without other explanation for pleural effusion. Malignancy was diagnosed by either cytology or biopsy. The cutoff value of ADA in TPE was 49 U/L, sensitivity was 89.2%, specificity was 70.4%, positive predictive value (PPV) was 84.4%, and negative predictive value (NPV) was 78.4%. ADA activity below 16 U/L suggests that TPE is highly unlikely with sensitivity=38.5%, specificity=100%, PPV=100%, and NPV=57.4%. ADA effusion/serum ratio reached a cutoff in TPE of 1.7 (sensitivity=84.6%, specificity=72.2%, PPV=81.4%, NPV=71.4%). Sensitivity, specificity, PPV, and NPV of cytology evaluation for TPE are 72.2%, 70.1%, 66.1%, and 75.8%, respectively. Pleuroscopy-guided pleural biopsy had sensitivity=66.7%, specificity=100%, PPV=100%, and NPV=78.8%. In 27.8% of TPE cases, pleural fluid cultures were positive. There is no doubt that pleuroscopy-guided biopsy is of great value for TPE diagnosis; however, sensitivity and specificity of noninvasive tests, especially ADA, can help to distinguish between TB and malignancy. 相似文献

SETTING: University Hospital, Bangkok, Thailand. OBJECTIVE: To evaluate the diagnostic value of antibody detection in serum and in pleural effusion as a marker of tuberculous pleuritis (TBP). DESIGN: Cross-sectional study. MATERIALS AND METHODS: One hundred and fifty-five patients with pleural effusion who underwent diagnostic evaluation at Siriraj Hospital between March 1999 and May 2000 were recruited. Samples of pleural fluid were examined biochemically, cytologically and microbiologically. Pathological examination of pleural tissue was also performed. The diagnosis of TBP or other diagnosis was made by either pathological finding or culture result. Immunochromatographic tuberculosis (ICT-TB) tests for antibody detection were then performed using the stored serum samples and effusions from those patients with a final definite diagnosis. This test detects antibodies to five secreted antigens of Mycobacterium tuberculosis, including the 38 kDa antigen. RESULTS: We investigated 67 patients with TBP, 44 with malignant pleural effusions, seven with transudates and one with cryptococcal pleuritis. The combined ICT-TB serum and effusion tests were positive in 34/67 TBP and 22/52 non-TBP patients. The sensitivity, specificity, positive predictive value and negative predictive value of the ICT-TB test were 50.7, 57.7, 60.7 and 47.6%, respectively. In 11 TBP patients with human immunodeficiency virus (HIV) co-infection, the sensitivity of the ICT-TB test was 45.6%. There was no correlation between the test positivity and culture result or duration of disease. CONCLUSIONS: The diagnostic value of antibody detection in TBP is modest in an area with intermediate prevalence of tuberculosis, independently of HIV serological status. 相似文献

Forty-eight cases of tuberculous pleurisy were examined and the following results were obtained. (1) Most of the patients were male, and there was no significant age and underlying diseases. (2) Fever and chest pain were observed mainly in younger patients, and sputum and dyspnea in older patients. (3) All of the cases examined had exudative pleural effusion, and increased ADA activity was frequently observed. (4) Mycobacterium tuberculosis was detected in the sputum of 65%, and also in the pleural effusion of 28% of the patients. The pathological diagnosis of tuberculosis was made by pleural biopsy in 83% of the patients, suggesting that pleural biopsy is very useful in the diagnosis of tuberculosis pleurisy. (5) The prognosis of the patients with tuberculosis pleurisy was good. Steroid therapy was generally ineffective. 相似文献

A clinical study of 38 patients (28 men and 10 women) with tuberculous pleurisy was conducted. The age of these patients ranged from 19 to 92 years, with an average age of 48.9 years. In 30 patients, the chief complaint was fever, and other common complaints included chest pain, dyspnea, and coughing. Bacillus tuberculosis was found in the pleural fluid of 7.9% of the patients. Tuberculous pleurisy was diagnosed histologically, based on pleural biopsy, in 23.7% of the patients. The diagnosis rate of pleural biopsy was 47.4%. There were no significant differences in results of blood and pleural fluid tests between idiopathic pleurisy and concomitant pleurisy, but the tuberculin skin test was positive in only 50% of the patients with concomitant pleurisy. The tendency was that the longer the time period between symptom onset and first examination, the greater the pleural fluid retention. The diagnosis rate of pleural biopsy was influenced by the severity of pleural fluid retention. A thoracic cavity drain was inserted for continuous drainage in 15 patients, and every patient underwent INH + RFP-based chemotherapy. Tuberculous pleurisy is an important disease among patients with pleural fluid retention, thus clinicians need to know how to treat this disease. 相似文献
