From June 1983 to September 1984, the pleural biopsies with Cope needle were performed at department of thoracic and cardiovascular surgery, Pusan Paik Hospital, Inje college, on 78 patients for exudative pleural effusion caused by various conditions. These results were analyzed clinically and summarized as follows: 2. The accuracy of pleural biopsy was 69.2% [54 of 78 patients]. The accuracy represented by ratio for the number of biopsy was 63.5% [54 of 85 biopsies]. 3. Among 61 patients of tuberculosis or malignancy, 37 [60.7%] were confirmed by pleural biopsy. 4. Tuberculosis was diagnosed in 48 patients, in 26[54.2%] out of these by pleural biopsy alone, in 3[6.2%] by pleural biopsy and isolation of AFB, in 2[4.2%] by pleural biopsy and operation, in 4[8.3%] by isolation of AFB, in 2[4.2%] by operation, and in 11[22.9%] clinically. 5. Among 13 patients of malignancy, 4[30.8%] were diagnosed by cytology alone, 4[30.8%] by pleural biopsy and cytology alone, 4[30.8%] by pleural biopsy and cytology, 1[7.7%] by pleural biopsy alone, 1[7.7%] by pleural biopsy and operation, and remained 3 by operation, lymph node biopsy, or bronchoscopy respectively. 6. False positive of clinical diagnosis was 12.5% for tuberculosis and 28.6% for malignancy. In pathological diagnosis there was no false positive. So specificity of pleural biopsy was very high. But false negative of pleural biopsy was 29.2% for tuberculosis and 46.2% for malignancy. 7. 4 cases[5.1%] of minimal pneumothorax were in the early series.

Background: The release of interferon-gamma (IFN-${\gamma}$) by T lymphocytes increases after rechallenge with Mycobacterium tuberculosis antigen, especially, at a localized site of tuberculosis (TB) infection. We aimed to compare the clincial efficacy of two commercial IFN-${\gamma}$ release assays from pleural fluid for the diagnosis in tuberculous pleurisy. Methods: We performed T-SPOT.TB and QuantiFERON-TB Gold tests simultaneously on pleural fluid and peripheral blood samples from patients with pleural effusion, in South Korea, an area with intermediate TB burden. Results: Thirty-six patients were enrolled prospectively, and tuberculous pleurisy was found in 21 patients. Both the numbers of IFN-${\gamma}$ secreting T cells and the concentration of IFN-${\gamma}$ were greater in the pleural tuberculous group, comparing with the non-tuberculous group. Moreover, in the tuberculous group, there was a significant difference in IFN-${\gamma}$ producing spot-forming cells using the T-SPOT.TB method between pleural fluid and peripheral blood. The receiver operating characteristic (ROC) curve, was the greatest for pleural fluid T-SPOT.TB test, followed by peripheral blood T-SPOT.TB test, peripheral blood QuantiFERON-TB Gold test, and pleural fluid QuantiFERON-TB Gold test (area under the ROC curve of 0.956, 0.890, 0.743, and 0.721, respectively). The T-SPOT.TB assay produced less indeterminate results than did QuantiFERON-TB Gold assay in both pleural fluid and peripheral blood. Conclusion: These findings suggest that the pleural fluid T-SPOT.TB test could be the most useful test among the IFN-${\gamma}$ release assays for diagnosing tuberculous pleurisy in an area with an intermediate prevalence of TB infection.

연구 배경: 결핵성 흉막염의 진단에 있어서 흉수에 대한 중합효소연쇄반응 검사는 매우 낮은 민감도를 보였으며, 이는 흉수 내의 결핵균의 수가 적은 데에 기인하는 것으로 추정된다. 이번 연구에서는 흉수의 검체양을 증가시켰을 때 결핵성 흉수에 대한 중합효소연쇄반응 검사의 민감도가 향상되는지를 알아보고자 하였다. 방 법: 결핵성 흉막염에 대한 감별 진단이 필요하였던 53명의 환자에 대하여 전향적인 연구를 시행하였다. 각각의 환자로부터 얻은 흉수를 10 ml, 25 ml, 50 ml로 양을 달리 하여 결핵균에 대한 중합효소연쇄반응 검사를 시행하였으며, Cobas Amplicor MTB (Roche Diagnostic Systems)를 이용하였다. 결핵성 흉막염은 흉수에서 결핵균이 배양된 경우, 흉막 생검에서 결핵이 진단된 경우, 가래에서 결핵균이 배양된 경우 및 기타 원인이 배제된 상태에서 임상적으로 결핵성 흉수가 의심되며 항결핵제 투약으로 흉수가 호전된 경우를 포함하였다. 결 과: 53명의 환자 중 26명이 결핵성 흉막염으로 진단되었다. 흉수에 대한 항산균 바름질, 결핵균 배양, 아데노신 디아미나아제 측정 및 흉막 생검의 민감도는 각각 3.8%, 15.4%, 88.5%, 84.6%이었다. 10 ml, 25 ml, 50 ml의 흉수를 이용한 결핵균 중합효소연쇄반응 검사는 각각 3명(11.5%), 4명(15.4%), 3명(11.5%)에서 양성이었으며, 통계적으로 유의한 차이를 보이지 않았다(p>0.05, symmetry exact 검사). 결 론: 결핵균의 수가 극히 적을 것으로 예상되는 흉수 등의 검사물에 대해서는 결핵균 중합효소연쇄반응 검사의 임상적 유용성이 극히 제한적이며, 검사물의 양을 증가시키더라도 민감도는 향상되지 않는다.

Pleural effusion is not a rare disease in Korea. The diagnosis of pleural effusion is very difficult, even though the patients often complain of typical symptoms indicating of pleural diseases. Pleural effusion is characterized by the pleural cavity filled with transudative or exudative pleural fluids, and it is developed by various etiologies. The presence of pleural effusion can be confirmed by radiological studies including simple chest radiography, ultrasonography, or computed tomography. Identifying the causes of pleural effusions by pleural fluid analysis is essential for proper treatments. This review article provides information on the diagnostic approaches of pleural effusions and further suggested ways to confirm their various etiologies, by using the most recent journals for references.

Increasing incidence of pleural infection has been reported worldwide in recent decades. The pathogens responsible for pleural infection are changing and differ from those in community acquired pneumonia. The main treatments for pleural infection are antibiotics and drainage of infected pleural fluid. The efficacy of intrapleural fibrinolytics remains unclear, although a recent randomized control study showed that the novel combination of tissue plasminogen activator and deoxyribonuclease had improved clinical outcomes. Surgical drainage is a critical treatment in patient with progression of sepsis and failure in tube drainage.

연구 배경: 결핵성 흉막삼출은 아직까지도 우리나라에서 가장 흔한 흉막삼출 원인으로 생각되고 있으나 기존의 검사로는 60% 정도의 확진만이 가능하다. 이에 보다 예민한 진단법의 개발이 요구되던 중 PCR의 발전으로 결핵성흉염의 진단에 도움을 줄 것으로 기대되었다. 여에 저자들은 PCR을 이용한 결핵성 흉막염 진단의 유용성을 알아보고자 하였다. 방법: 환자군으로 결핵성 흉막염으로 확진된 경우와 임상적으로 결핵성 흉막엽으로 의심이된 각각 7명의 선정하였고 대조군으로 결핵의 과거력이 없었던 7명의 악성종양 환자의 흉수를 각각 사용하여 PCR을 시행하였으며, PCR의 target은 IS6110 gene의 일부인 123bp DNA로 하였고 DNA추출은 Eisennach 방법(1991)을 변형하여 사용하였다. 결과: 1) PCR의 감수성검사에서 자외선 발광경하에서 50fg DNA에서 양성 임을 확인하였다. 2) 조직병리학적 및 미생물학적 방법으로 확진된 결핵성 흉막염 환자중 85.7%(6/7)에서 PCR양성을 나타내었고, 임상적으로 결핵성 흉막염이 의심된 환자중 71.5%(5/7)에서 PCR 양성을 나타내었다. 3) 대조군 7예는 모두 PCR 음성이었다. 결론: 이상의 결과로서 결핵성 흉막액의 진단에 있어서 IS6110을 이용한 PCR법은 고식적인 진단방법에 비하여 결핵균의 신속하고 정확한 진단을 가능하게 해주는 유용한 방법임을 알 수 있었으나 비용을 절감할 수 있고 오염을 줄일 수 있는 방법에 대한 연구가 더 필요하리라 생각된다.

Background: Thoracoscopic pleural biopsy is often required for rapid and confirmative diagnosis in patients with suspected pleural tuberculosis (PL-TB). However, this method is more invasive and costly than its alternatives. Therefore, we evaluated the clinical utility of the chest computed tomography (CT)-based bronchial aspirate (BA) TB-polymerase chain reaction (PCR) test in such patients. Methods: Bronchoscopic evaluation was performed in 54 patients with presumptive PL-TB through diagnostic thoracentesis but without a positive result of sputum acid-fast bacilli (AFB) smear, pleural fluid AFB smear, or pleural fluid TB-PCR test. Diagnostic yields of BA were evaluated according to the characteristics of parenchymal lesions on chest CT. Results: Chest radiograph and CT revealed parenchymal lesions in 25 (46%) and 40 (74%) of 54 patients, respectively. In cases with an absence of parenchymal lesions on chest CT, the bronchoscopic approach had no diagnostic benefit. BA TB-PCR test was positive in 21 out of 22 (95%) patients with early-positive results. Among BA results from 20 (37%) patients with patchy consolidative CT findings, eight (40%) were AFB smear-positive, 18 (90%) were TB-PCR-positive, and 19 (95%) were culture-positive. Conclusion: The BA TB-PCR test seems to be a satisfactory diagnostic modality in patients with suspected PL-TB and patchy consolidative CT findings. For rapid and confirmative diagnosis in these patients, the bronchoscopic approach with TB-PCR may be preferable to the thoracoscopy.

Background: Tuberculous pleurisy is the leading cause of pleural effusion in Korea. And differential diagnosis of tuberculous pleurisy with other cause is clinically very important. Traditional diagnostic methods such as routine analysis of pleural fluid, staining for acid-fast bacilli or pleural biopsy have major inherent limitaion. This study was designed to evaluate the significance of pleural fluid polymerase chain reaction(PCR) and adenosine deaminase (ADA) activity in early diagnosis of tuberculous pleurisy. Material and Method: Between March 1996 and July 1997, 198 patients with pleural effusion reviewed retrospectively. The study group included 112 cases with tuberculous effusion and 86 cases with non-tuberculous effusions, whose diagnoses were confirmed by pleural biopsy, microbiological methods, or cytology. We compared the results of PCR and pleural fluid levels of ADA between tuberculous and non-tuberculous effusions. Result: Mean age was 47.54$\pm$19.52 years(range 2 to 85 years). The positive rate of PCR was significantly higher in tuberculous group than non-tuberculous group(p<0.05). The sensitivty, specificity, positive predictive value(PPV), and negative predictive value(NPV) for PCR were 31.7, 90.9, 83.0, and 48.8%, respectively. Mean ADA activity was significantly higher in tuberculous group than non-tuberculous group(83.2 U/L vs 49.8 U/L)(p<0.05). With diagnostic thresholds of 40 U/L, the sensitivity, specificity, PPV, and NPV of ADA for tuberculosis were 75.9, 70.9, 77.3, and 69.3% respectively. At a level of 70 U/L, the sensitivity, specificity, PPV, and NPV of ADA for tuberculosis were 70.1, 75.9, 82.9, and 60.3% respectively. Conclusion: PCR is very highly specific, but less sensitive methods in diagnosis of tuberculous pleurisy. But ADA level of pleural fluid has acceptable sensitivity and specificity in diagnosis of tuberculous pleurisy. ADA activity is more useful test in the evaluation of pleural effusions.
