Abstract
Pleural tuberculosis (TB) is common and often follows a benign course but may result in serious long-term morbidity. Diagnosis is challenging because of the paucibacillary nature of the condition. Advances in Mycobacterium culture media and PCR-based techniques have increased the yield from mycobacteriologic tests. Surrogate biomarkers perform well in diagnostic accuracy studies but must be interpreted in the context of the pretest probability in the individual patient. Confirming the diagnosis often requires biopsy, which may be acquired through thoracoscopy or image-guided closed pleural biopsy. Treatment is standard anti-TB therapy, with optional drainage and intrapleural fibrinolytics or surgery in complicated cases.

Abstract
Background: Tuberculosis (TB) is the world's leading cause of death from infectious disease. The World Health Organization (WHO) recognized 6.3 million new TB cases in 2017, 16% corresponding to extrapulmonary forms; pleural tuberculosis (PT) is the most common extrapulmonary form in adults. PT diagnosis is often challenging because the scarcity of bacilli in pleural fluid (PF), sometimes requiring invasive procedures to obtain pleural tissue for histological, microbiological or molecular examination. In regions of medium and high disease prevalence, adenosine deaminase (ADA), interferon gamma (IFN-γ) and interleukin 27 (IL-27) dosages are useful to establish presumptive diagnosis in patients with compatible clinical/radiological picture who present with lymphocytic pleural effusion. PT treatment is similar to the pulmonary TB treatment regimen recommended by WHO. Area covered: In this update, we present a PT review, including epidemiology, pathogenesis, clinical features, diagnosis, and therapy. Expert opinion: There is no PF test alone accurate for PT diagnosis, despite the evolution in clinical laboratory. ADA, IFN-γ and IL-27 are valuable laboratory biomarkers; however, IFN-γ and IL-27 are quite expensive. Molecular tests present low sensitivity in PF, being useful for diagnostic confirmation. Multidrug therapy remains the PT treatment choice. Advancing research in immunotherapy may bring benefits to PT patients.

Abstract
PURPOSE OF REVIEW Pleural infection remains an important pulmonary disease, causing significant morbidity and mortality. There is a resurgence of disease burden despite introduction of antibiotics and pneumococcal vaccines. A revisit of the pathogenesis and update on intervention may improve the care of pleural infection. RECENT FINDINGS Recent studies have uncovered the prognostic implication of the presence of a pleural effusion in patients with pneumonia. Identifying where the bacteria lives may have diagnostic and therapeutic implications. Over-exaggerated pleural inflammation may underlie development of parapneumonic effusion as indirect evidence and a randomized study in children raised a role of corticosteroids in parapneumonic pleural effusions, but data are lacking for adults. Optimization of the delivery regimen of intrapleural fibrinolytic and deoxyribonuclease therapy is ongoing. SUMMARY The review aims to review the current practice and explore new directions of treatment on pleural infection.

Respir Med 2018; 139:86-90. [PMID: 29858007 DOI: 10.1016/j.rmed.2018.05.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2017] [Revised: 03/14/2018] [Accepted: 05/01/2018] [Indexed: 11/25/2022]
Abstract
BACKGROUND Adjunctive use of corticosteroids with anti-tuberculosis (TB) therapy has been reported to benefit people with tuberculous pleural effusion (TPE), while there is a paucity of data to support it as routine use. TPE can be subdivided into free-flowing type and loculated type. We evaluated the effects of adjunctive prednisolone therapy on functional sequelae, pleural thickening and pleural adhesions in patients with free-flowing TPE. METHODS This is a retrospective cohort study, conducted from Jan 2013 to Dec 2016 (ChiCTR-ORC-16009267). All the patients were diagnosed with TPE, and treated with standard 4-drug anti-TB chemotherapy regimen and complete drainage of the effusion. We compared the incidence of a composite of roentgenographic sequelae (pleural thickening of > 2 mm, or pleural adhesions and costophrenic angle > 90°), or restrictive functional sequelae (FVC/FVC pre or TLC/TLC pre < 80%) between those who received adjunctive prednisolone therapy and those who did not. RESULTS The final cohorts consisted of 135 subjects. Of those, 56 received adjunctive prednisolone therapy and 79 did not. The incidence of a composite of roentgenographic sequelae or restrictive functional sequelae was significantly decreased in the prednisolone group as compared with the control group (51.8% vs. 75.9%; RR 2.83, 95% confidence interval, 1.27-6.31, P = 0.011). No serious side effects due to corticosteroid were noted. CONCLUSIONS This study detected a significant association between adjunctive prednisolone therapy and decreased incidence of a composite of radiographic sequelae, or functional sequelae in HIV-negative, free-flowing type TPE patients treated with adjunctive prednisolone.

Abstract
The aim of this study was to determine whether twinkling artifact (TA) detected on color Doppler ultrasonography can effectively determine the presence of pleural calcification compared with computed tomography (CT) and differentiate tuberculous pleuritis (TP) and cancerous pleuritis (CP). One hundred six cases of TP and 26 cases of CP were scanned using gray-scale ultrasonography (GSU) and TA to determine the presence of pleural calcification. With CT as the reference standard, 63.3% and 79.6% of patients with pleural calcification were identified with GSU and TA, respectively. The detection rate of TA was higher than that of GSU (p = 0.039). For the whole study population, 37.1% were identified as having pleural calcification with CT, significantly higher than the proportion detected with GSU (25.8%, p = 0.001), but not different from that detected with TA (41.7%, p = 0.327). The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of TA were 79.6%, 80.7%, 80.3%, 70.9% and 87.0%, respectively. The detection rate of TA was significantly higher than that of GSU (p <0.001). When GSU was combined with TA (GSUTA), the positive rate in the TP group was significantly higher than that in the CP group (χ2 < 0.001). In conclusion, TA is comparable to CT and more sensitive than GSU in the detection of pleural calcification. Evaluation for GSUTA on pleura may help to differentiate TP from CP.

Abstract
Purpose To evaluate the efficacy and safety of adjunctive corticosteroids in the treatment of patients with tuberculous pleurisy. Methods The PubMed, Cochrane, Medline, Embase, Web of Science and Chinese National Knowledge Infrastructure were searched. Clinical trials of corticosteroids compared with control were eligible for inclusion. Results Ten studies (6 randomized controlled trials [RCTs] and 4 non-RCTs) with 957 participants met the inclusion criteria. Compared to the controls (placebos or non-steroids), adjunctive corticosteroid use reduced the risk of residual pleural fluid after 4 weeks and the number of days to symptom improvement; however, there was no convincing evidence to support the positive effects of corticosteroids over the long term (8 weeks) on residual pleural fluid, pleural thickening, or pleural adhesions, and there was no statistical difference between the corticosteroid group and control group with respect to 7-days relief of the clinical symptoms or death from any cause. In addition, more adverse events were observed in patients who received corticosteroids than in those in the control group. Conclusions Our results suggest that adjunctive corticosteroid use did not improve long-term efficacy and might induce more adverse events, although the risk of residual pleural fluid at 4 weeks and the number of days to symptom improvement were reduced.

Abstract
BACKGROUND Corticosteroids used in addition to antituberculous therapy have been reported to benefit people with tuberculous pleurisy. However, research findings are inconsistent and raise doubt as to whether such treatment is worthwhile. There is also concern regarding the potential adverse effects of corticosteroids, especially in HIV-positive people. OBJECTIVES To evaluate the effects of adding corticosteroids to drug regimens for tuberculous pleural effusion. SEARCH METHODS In April 2016, we searched the Cochrane Infectious Diseases Group Specialized Register, CENTRAL (the Cochrane Library), MEDLINE, Embase, LILACS, Current Controlled Trials, and the reference lists of articles identified by the literature search. SELECTION CRITERIA Randomized controlled trials (RCTs) and quasi-RCTs that compared any corticosteroid with no treatment, placebo, or other active treatment (both groups should have received the same antituberculous drug regimen) in people diagnosed with tuberculous pleurisy. DATA COLLECTION AND ANALYSIS Two review authors independently screened the search results, extracted data from the included trials, and assessed trial methodological quality using the Cochrane 'Risk of bias' tool. We analysed the data using risk ratios (RR) with 95% confidence intervals (CIs). We applied the fixed-effect model in the absence of statistically significant heterogeneity. MAIN RESULTS Six trials with 590 participants met the inclusion criteria, which were conducted in Asia (three trials), Africa (two trials), and Europe (one trial). Two trials were in HIV-negative people, one trial was in HIV-positive people, and three trials did not report HIV status.Corticosteroids may reduce the time to resolution of pleural effusion. Risk of residual pleural effusion on chest X-ray was reduced by 45% at eight weeks (RR 0.54, 95% CI 0.37 to 0.78; 237 participants, 2 trials, low certainty evidence), and 65% at 24 weeks (RR 0.35, 95% CI 0.18 to 0.66; 237 participants, 2 trials, low certainty evidence).Compared with control, corticosteroids may reduce the risk of having pleural changes (such as pleural thickening or pleural adhesions), on chest X-ray at the end of follow-up by almost one third (RR 0.72, 95% CI 0.57 to 0.92; 393 participants, 5 trials,low certainty evidence), which translates to an absolute risk reduction of 16%.One trial reported deaths in people that were HIV-positive, with no obvious difference between the groups; the trial authors' analysis suggests that the deaths observed in this trial were related to HIV disease rather than pleural TB (RR 0.91, 95% CI 0.64 to 1.31; 197 participants, 1 trial).We found limited data on long-term functional respiratory impairment on 187 people in two trials, which reported that average percentage predicted forced vital capacity was similar in the group receiving prednisolone and in the control group (very low certainty evidence).The risk of adverse events that led to discontinuation of the trial drug was higher in people with pleural TB receiving corticosteroids (RR 2.78, 95% CI 1.11 to 6.94; 587 participants, 6 trials, low certainty evidence). The trial in HIV-positive people reported on six different HIV-related infections, with no obvious differences. However, cases of Kaposi's sarcoma were only seen in the corticosteroid group (with 6/99 cases in the steroid group compared to 0/98 in the control group) (very low certainty evidence). AUTHORS' CONCLUSIONS Long-term respiratory function is potentially the most important outcome for assessing the effects of adjunctive treatments for people with pleural TB. However, the information on the impact of pleural TB on long-term respiratory function is unknown and could be eclipsed by other risk factors, such as concurrent pulmonary TB, smoking, and HIV. This probably needs to be quantified to help decide whether further trials of corticosteroids for pleural TB would be worthwhile.

Abstract
The American Thoracic Society, Centers for Disease Control and Prevention, and Infectious Diseases Society of America jointly sponsored the development of this guideline for the treatment of drug-susceptible tuberculosis, which is also endorsed by the European Respiratory Society and the US National Tuberculosis Controllers Association. Representatives from the American Academy of Pediatrics, the Canadian Thoracic Society, the International Union Against Tuberculosis and Lung Disease, and the World Health Organization also participated in the development of the guideline. This guideline provides recommendations on the clinical and public health management of tuberculosis in children and adults in settings in which mycobacterial cultures, molecular and phenotypic drug susceptibility tests, and radiographic studies, among other diagnostic tools, are available on a routine basis. For all recommendations, literature reviews were performed, followed by discussion by an expert committee according to the Grading of Recommendations, Assessment, Development and Evaluation methodology. Given the public health implications of prompt diagnosis and effective management of tuberculosis, empiric multidrug treatment is initiated in almost all situations in which active tuberculosis is suspected. Additional characteristics such as presence of comorbidities, severity of disease, and response to treatment influence management decisions. Specific recommendations on the use of case management strategies (including directly observed therapy), regimen and dosing selection in adults and children (daily vs intermittent), treatment of tuberculosis in the presence of HIV infection (duration of tuberculosis treatment and timing of initiation of antiretroviral therapy), as well as treatment of extrapulmonary disease (central nervous system, pericardial among other sites) are provided. The development of more potent and better-tolerated drug regimens, optimization of drug exposure for the component drugs, optimal management of tuberculosis in special populations, identification of accurate biomarkers of treatment effect, and the assessment of new strategies for implementing regimens in the field remain key priority areas for research. See the full-text online version of the document for detailed discussion of the management of tuberculosis and recommendations for practice.

Abstract
Background Tuberculosis is an important risk factor for chronic respiratory disease in resource poor settings. The persistence of abnormal spirometry and symptoms after treatment are well described, but the structural abnormalities underlying these changes remain poorly defined, limiting our ability to phenotype post-TB lung disease in to meaningful categories for clinical management, prognostication, and ongoing research. The relationship between post-TB lung damage and patient-centred outcomes including functional impairment, respiratory symptoms, and health related quality of life also remains unclear. Methods We performed a systematic literature review to determine the prevalence and pattern of imaging-defined lung pathology in adults after medical treatment for pleural, miliary, or pulmonary TB disease. Data were collected on study characteristics, and the modality, timing, and findings of thoracic imaging. The proportion of studies relating imaging findings to spirometry results and patient morbidity was recorded. Study quality was assessed using a modified Newcastle-Ottowa score. (Prospero Registration number CRD42015027958) Results We identified 37 eligible studies. The principle features seen on CXR were cavitation (8.3–83.7%), bronchiectasis (4.3–11.2%), and fibrosis (25.0–70.4%), but prevalence was highly variable. CT imaging identified a wider range of residual abnormalities than CXR, including nodules (25.0–55.8%), consolidation (3.7–19.2%), and emphysema (15.0–45.0%). The prevalence of cavitation was generally lower (7.4–34.6%) and bronchiectasis higher (35.0–86.0%) on CT vs. CXR imaging. A paucity of prospective data, and data from HIV-infected adults and sub-Saharan Africa (sSA) was noted. Few studies related structural damage to physiological impairment, respiratory symptoms, or patient morbidity. Conclusions Post-TB structural lung pathology is common. Prospective data are required to determine the evolution of this lung damage and its associated morbidity over time. Further data are required from HIV-infected groups and those living in sSA.

Abstract
Although it is curable, tuberculosis remains one of the most frequent causes of pleural effusions on a global scale, especially in developing countries. Tuberculous pleural effusion (TPE) is one of the most common forms of extrapulmonary tuberculosis. TPE usually presents as an acute illness with fever, cough and pleuritic chest pain. The pleural fluid is an exudate that usually has predominantly lymphocytes. The gold standard for the diagnosis of TPE remains the detection of Mycobacterium tuberculosis in pleural fluid, or pleural biopsy specimens, either by microscopy and/or culture, or the histological demonstration of caseating granulomas in the pleura along with acid fast bacilli, Although adenosine deaminase and interferon-γ in pleural fluid have been documented to be useful tests for the diagnosis of TPE. It can be accepted that in areas with high tuberculosis prevalence, the easiest way to establish the diagnosis of TPE in a patient with a lymphocytic pleural effusion is to generally demonstrate a adenosine deaminase level above 40 U/L. The recommended treatment for TPE is a regimen with isoniazid, rifampin, and pyrazinamide for two months followed by four months of two drugs, isoniazid and rifampin.

Abstract
When a patient presents with new pleural effusion, the diagnosis of tuberculous (TB) pleuritis should be considered. The patient is at risk for developing pulmonary or extrapulmonary TB if the diagnosis is not made. Between 3% and 25% of patients with TB will have TB pleuritis. The incidence of TB pleuritis is higher in patients who are human immunodeficiency virus (HIV)-positive. Pleural fluid is an exudate that usually has a predominance of lymphocytes. The easiest way to diagnose TB pleuritis in a patient with lymphocytic pleural effusion is to demonstrate a pleural fluid adenosine deaminase level above 40 IU/L. The treatment for TB pleuritis is the same as that for pulmonary TB. Tuberculous empyema is a rare occurrence, and the treatment is difficult.

Abstract
BACKGROUND Tuberculosis causes approximately 8.6 million disease episodes and 1.3 million deaths worldwide per year. Although curable with standardized treatment, outcomes for some forms of tuberculosis are improved with adjunctive corticosteroid therapy. Whether corticosteroid therapy would be beneficial in treating people with pulmonary tuberculosis is unclear. OBJECTIVES To evaluate whether adjunctive corticosteroid therapy reduces mortality, accelerates clinical recovery or accelerates microbiological recovery in people with pulmonary tuberculosis. SEARCH METHODS We identified studies indexed from 1966 up to May 2014 by searching: Cochrane Infectious Diseases Group's trials register, Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and LILACS using comparative search terms. We handsearched reference lists of all identified studies and previous reviews and contacted relevant researchers, organizations and companies to identify grey literature. SELECTION CRITERIA Randomized controlled trials and quasi-randomized control trials of recognized antimicrobial combination regimens and corticosteroid therapy of any dose or duration compared with either no corticosteroid therapy or placebo in people with pulmonary tuberculosis were included. DATA COLLECTION AND ANALYSIS At least two investigators independently assessed trial quality and collected data using pre-specified data extraction forms. Findings were reported as narrative or within tables. If appropriate, Mantel-Haenszel meta-analyses models were used to calculate risk ratios. MAIN RESULTS We identified 18 trials, including 3816 participants, that met inclusion criteria. When compared to taking placebo or no steroid, corticosteroid use was not shown to to reduce all-cause mortality, or result in higher sputum conversion at 2 months or at 6 months (mortality: RR 0.77, 95%CI 0.51 to 1.15, 3815 participants, 18 studies, low quality evidence; sputum conversion at 2 months RR 1.03, 95%CI 0.97 to 1.09, 2750 participants, 12 studies; at 6 months; RR1.01, 95%CI 1.01, 95%CI 0.98 to 1.04, 2150 participants, 9 studies, both low quality evidence). However, corticosteroid use was found to increase weight gain (data not pooled, eight trials, 1203 participants, low quality evidence), decrease length of hospital stay (data not pooled, three trials, participants 379, very low quality of evidence) and increase clinical improvement within one month (RR 1.16, 95% CI 1.09 to 1.24; five trials, 497 participants, low quality evidence). AUTHORS' CONCLUSIONS It is unlikely that adjunctive corticosteroid treatment provides major benefits for people with pulmonary tuberculosis. Short term clinical benefits found did not appear to be maintained in the long term. However, evidence available to date is of low quality. In order to evaluate whether adjunctive corticosteroids reduce mortality, or accelerate clinical or microbiological recovery in people with pulmonary tuberculosis further large randomized control trials sufficiently powered to detect changes in such outcomes are needed.

Abstract
Tuberculous pleurisy is the most common form of extrapulmonary tuberculosis in Korea. Tuberculous pleurisy presents a diagnostic and therapeutic problem due to the limitations of traditional diagnostic tools. There have been many clinical research works during the past decade. Recent studies have provided new insight into the tuberculous pleurisy, which have a large impact on clinical practice. This review is a general overview of tuberculous pleurisy with a focus on recent findings on the diagnosis and management.

Abstract
Tuberculous pleural effusion (TBPE) is the most common form of extrapulmonary tuberculosis (TB) in Spain, and is one of the most frequent causes of pleural effusion. Although the incidence has steadily declined (4.8 cases/100,000population in 2009), the percentage of TBPE remains steady with respect to the total number of TB cases (14.3%-19.3%). Almost two thirds are men, more than 60% are aged between 15-44years, and it is more common in patients with human immunodeficiency virus. The pathogenesis is usually a delayed hypersensitivity reaction. Symptoms vary depending on the population (more acute in young people and more prolonged in the elderly). The effusion is almost invariably a unilateral exudate (according to Light's criteria), more often on the right side, and the tuberculin test is negative in one third of cases. There are limitations in making a definitive diagnosis, so various pleural fluid biomarkers have been used for this. The combination of adenosine deaminase and lymphocyte percentage may be useful in this respect. Treatment is the same as for any TB. The addition of corticosteroids is not advisable, and chest drainage could help to improve symptoms more rapidly in large effusions.

Abstract
BACKGROUND The effects of corticosteroids are systemic, but their benefits in tuberculosis are thought to be organ specific, with clinicians using them routinely to treat some forms of tuberculosis (such as meningitis), but not others. We aimed to assess the effects of steroids on mortality attributable to all forms of tuberculosis across organ systems. METHODS We did a systematic review and meta-analysis to estimate the efficacy of steroids for the prevention of mortality in all forms of tuberculosis, and to quantify heterogeneity in this outcome between affected organ systems. We searched the Cochrane Infectious Diseases Group trials register, the Cochrane Central Register of Controlled Trials, Medline, Embase, and Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) for studies published up to Sept 6, 2012, and checked reference lists of included studies and relevant reviews. We included all trials in people with tuberculosis in any organ system, with tuberculosis defined clinically or microbiologically. There were no restrictions by age, comorbidity, publication language, or type, dose, or duration of steroid treatment. We used the Mantel-Haenszel method to summarise mortality across trials. FINDINGS We identified 41 eligible trials, 18 of which assessed pulmonary tuberculosis. 20 of the 41 trials (including 13 of those for pulmonary tuberculosis) were done before the introduction of modern rifampicin-containing antituberculosis chemotherapy. Meta-analysis stratified by affected organ systems identified no heterogeneity; steroids reduced mortality by 17% (risk ratio [RR] 0·83, 95% CI 0·74-0·92; I(2) 0%), consistent across all organ groups. In a sensitivity analysis that only included trials that used rifampicin-containing regimens, the results were similar (RR 0·85, 95% CI 0·74-0·98; I(2) 21%). A sensitivity analysis in pulmonary tuberculosis that excluded trials with high potential risks of bias suggested a slight benefit, but the point estimate was closer to no effect and the difference was not significant (RR 0·93, 95% CI 0·60-1·44). INTERPRETATION Steroids could be effective in reducing mortality for all forms of tuberculosis, including pulmonary tuberculosis. However, further evidence is needed since few recent trials have assessed the effectiveness of corticosteroids in patients with pulmonary tuberculosis.

Abstract
The possibility of tuberculous pleuritis should be considered in every patient with an undiagnosed pleural effusion, for if this diagnosis is not made the patient will recover only to have a high likelihood of subsequently developing pulmonary or extrapulmonary tuberculosis Between 3% and 25% of patients with tuberculosis will have tuberculous pleuritis. The incidence of pleural tuberculosis is higher in patients who are HIV positive. Tuberculous pleuritis usually presents as an acute illness with fever, cough and pleuritic chest pain. The pleural fluid is an exudate that usually has predominantly lymphocytes. Pleural fluid cultures are positive for Mycobacterium tuberculosis in less than 40% and smears are virtually always negative. The easiest way to establish the diagnosis of tuberculous pleuritis in a patient with a lymphocytic pleural effusion is to generally demonstrate a pleural fluid adenosine deaminase level above 40 U/L. Lymphocytic exudates not due to tuberculosis almost always have adenosine deaminase levels below 40 U/L. Elevated pleural fluid levels of gamma-interferon also are virtually diagnostic of tuberculous pleuritis in patients with lymphocytic exudates. In questionable cases the diagnosis can be established by demonstrating granulomas or organisms on tissue specimens obtained via needle biopsy of the pleura or thoracoscopy. The chemotherapy for tuberculous pleuritis is the same as that for pulmonary tuberculosis.

The use of adjunctive corticosteroids in the treatment of pericardial, pleural and meningeal tuberculosis: do they improve outcome? Respir Med 2008; 102:793-800.

Abstract
Tuberculosis remains a major cause of mortality and morbidity on a global scale. Effective anti-tuberculous chemotherapy has improved outcomes for individuals suffering from tuberculosis, although the disease often results in significant and permanent damage to organs. The use of adjunctive corticosteroid treatment has been studied with a view to demonstrating a reduction in inflammatory events that may improve outcomes for both mortality and morbidity. Cochrane reviews have summarized the evidence for adjunctive corticosteroids in the treatment of tuberculous pericarditis, meningitis and pleural effusion. These reviews have shown improved mortality for pericarditis and meningitis, but inconclusive effects for pericardial constriction and ongoing neurological disability. Rapid improvements in clinical parameters for pleural effusion were not supported by any lasting improved outcomes for these patients.

Abstract
BACKGROUND Corticosteroids used in addition to antituberculous therapy have been reported to benefit people with tuberculous pleurisy. However, research findings are inconsistent, raising doubt as to whether such treatment is worthwhile. Concern also exists regarding the potential adverse effects of corticosteroids, especially in HIV-positive people. OBJECTIVES To evaluate the effects of adding corticosteroids to drug regimens for tuberculous pleural effusion. SEARCH STRATEGY In May 2007, we searched the Cochrane Infectious Diseases Group Specialized Register, CENTRAL (The Cochrane Library 2007, Issue 2), MEDLINE, EMBASE, LILACS, Current Controlled Trials, and reference lists of articles. SELECTION CRITERIA Randomized and quasi-randomized controlled trials comparing any corticosteroid with no treatment, placebo, or other active treatment (both groups should receive the same antituberculous drug regimen) in people diagnosed with tuberculous pleurisy. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial methodological quality and extracted data. Data were analysed using relative risks (RR) and weighted mean difference (WMD) with 95% confidence intervals (CI). The fixed-effect model was applied in the absence of statistically significant heterogeneity. MAIN RESULTS Six trials with 633 participants met the inclusion criteria; one trial included only HIV-positive people. Compared to control, corticosteroid use was associated with less residual pleural fluid at four weeks (RR 0.76, 95% CI 0.62 to 0.94; 394 participants, 3 trials) and reduced pleural thickening (RR 0.69, 95% CI 0.51 to 0.94; 309 participants, 4 trials). We found no evidence of an effect of corticosteroids on death from any cause (194 participants, 1 trial), respiratory function (191 participants, 2 trials), residual pleural fluid at eight weeks (399 participants, 4 trials), or pleural adhesions (123 participants, 2 trials). Although discontinuation of treatment due to adverse events was more frequent in participants receiving corticosteroids than placebo (RR 2.80, 95% CI 1.12 to 6.98; 586 participants, 6 trials), the effects were generally mild. The risk of Kaposi sarcoma may be increased in HIV-positive people receiving corticosteroids (RR 13.00, 95% CI 0.74 to 227.63; 194 participants, 1 trial). AUTHORS' CONCLUSIONS There are insufficient data to support evidence-based recommendations regarding the use of adjunctive corticosteroids in people with tuberculous pleurisy. Randomized controlled trials that are sufficiently powered to evaluate the effects of corticosteroids on both morbidity and mortality are needed. The effects of corticosteroids on HIV-related complications, such as Kaposi sarcoma, should be assessed in people co-infected with HIV.

Abstract
The therapeutic scheme for initial pulmonary tuberculosis recommended by the SAEI is as follows: Initial phase, isoniazid, rifampin and pyrazinamide given daily for 2 months. In HIV(+) patients and immigrants from areas with a rate of primary resistance to isoniazid > 4%, ethambutol should be added until susceptibility studies are available. Second phase (continuation phase): rifampin and isoniazid, given daily or intermittently for 4 months in the general population. HIV(+) patients (< or = 200 CD4) and culture-positive patients after 2 months of treatment should receive a 7-month continuation phase. A 6-month regimen is recommended for extrapulmonary tuberculosis, with the exception of tuberculous meningitis, which should be treated for a minimum of 12 months and bone/joint tuberculosis, treated for a minimum of 9 months. Treatment regimens for multidrug resistant tuberculosis are based on expert opinion. These would include a combination of still-useful first-line drugs, injectable agents, and alternative agents, such as quinolones. Patients who present a special risk of transmitting the disease or of non-adherence should be treated with directly observed therapy.

Abstract
Tuberculous (TB) pleural effusion occurs in approximately 5% of patients with Mycobacterium tuberculosis infection. The HIV pandemic has been associated with a doubling of the incidence of extrapulmonary TB, which has resulted in increased recognition of TB pleural effusions even in developed nations. Recent studies have provided insights into the immunopathogenesis of pleural TB, including memory T-cell homing and chemokine activation. The definitive diagnosis of TB pleural effusions depends on the demonstration of acid-fast bacilli in the sputum, pleural fluid, or pleural biopsy specimens. The diagnosis can be established in a majority of patients from the clinical features, pleural fluid examination, including cytology, biochemistry, and bacteriology, and pleural biopsy. Measurement of adenosine deaminase and interferon-gamma in the pleural fluid and polymerase chain reaction for M tuberculosis has gained wide acceptance in the diagnosis of TB pleural effusions. Although promising, these tests require further evaluation before their routine use can be recommended. The treatment of TB pleural effusions in patients with HIV/AIDS is essentially similar to that in HIV-negative patients. At present, evidence regarding the use of corticosteroids in the treatment of TB pleural effusion is not clear-cut.

Abstract
AIM To assess the effect of intrapleural urokinase, vis-à-vis simple pleural drainage, on residual pleural thickening in a series of patients suffering from loculated tuberculous pleural effusion. PATIENTS AND METHOD Twenty-nine patients (21 males and 8 females) with loculated pleural effusion were studied. These patients were randomly allocated to one of two groups: one group received intrapleural urokinase (n=12) and the other was treated by simple drainage with suction (n=17). The urokinase (125,000 UI) was administered into the pleural cavity via an intrathoracic tube. This procedure was repeated every 12h until the quantity of pleural fluid obtained was less than 50 cm3, at which point the intrathoracic tube was removed. RESULTS In both groups, the biochemical analysis of the pleural fluid was an exudate and the fluid had a serous appearance. Pleural thickening when the drainage tube was removed was 8.09+/-3.36 mm for the group treated with urokinase, and 14.78+/-17.20mm (P>0.05) for the control group. Residual pleural thickening measured upon completion of medical treatment at 6 months was 1.45+/-0.89 mm for the group treated with urokinase and 7.47+/-10.95 mm for the control group (P<0.05). In the control group, only two patients presented over 10mm of residual pleural thickening. The mean quantity of fluid drained in the two groups was 1.487+/-711 ml for the patients with urokinase, and 795+/-519 ml for the control group (P<0.01). CONCLUSION Our study shows that patients with loculated tuberculous pleural effusion treated with urokinase suffered less from residual pleural thickening, as measured after six months, than those treated by simple drainage. It is therefore suggested that the administration of intrapleural urokinase is a safe and effective treatment for those patients who drain a larger quantity of pleural fluid.

Abstract
Pleural fibrosis can result from a variety of inflammatory processes. The response of the pleural mesothelial cell to injury and the ability to maintain its integrity are crucial in determining whether normal healing or pleural fibrosis occurs. The pleural mesothelial cell, various cytokines, and disordered fibrin turnover are involved in the pathogenesis of pleural fibrosis. The roles of these mediators in producing pleural fibrosis are examined. This article reviews the most common clinical conditions associated with the development of pleural fibrosis. Fibrothorax and trapped lung are two unique and uncommon consequences of pleural fibrosis. The management of pleural fibrosis, including fibrothorax and trapped lung, is discussed.

Abstract
Tuberculosis (TB) can spread to any tissue or organ of the body by way of hematogenous or lymphatic dissemination or contiguity. However, pulmonary TB is the most common presentation and the only form of the disease of epidemiologic importance. Consequently, the literature on the various forms of extrapulmonary TB (EPTB) is scant, and most of the published authors are specialists in specific extrapulmonary forms. As a result, in most of the major areas of study of EPTB, recommendations similar to those for pulmonary TB or others based on little or no evidence have been accepted. This lack of evidence is of particular concern in the case of treatment guidelines. The present article reviews important work that has given rise to current treatment guidelines. While most of these guidelines reveal the lack of evidence available on this subject, it can, nevertheless, be concluded that a 6-month treatment regimen similar to that used in patients with pulmonary TB may be sufficient to treat all forms of EPTB, including meningeal disease. The role of steroids and surgery in the treatment of TB affecting different sites is also discussed. Other topics dealt with are the considerations that should be taken into account and the treatment modifications necessary in patients infected with the human immunodeficiency virus.

Abstract
OBJECTIVE The aim of the present study was to evaluate the utility of serum and pleural fluid biomarkers for predicting residual pleural scarring (RPS) in tuberculous pleuritis. METHODOLOGY A retrospective study of patients with pleural tuberculosis was performed. Demographic data, clinical parameters, haematological indices, serum and pleural fluid biochemistry and pleural effusion area were assessed for correlation with the extent of RPS. RESULTS RPS was found in 41.4% of the 70 cases evaluated, with significant pleural scarring being present in 7.1%. It was more common in males (odds ratio 5.55). Among the variables studied, only the percentage reduction of the effusion after 2 weeks of treatment was found to independently predict the extent of RPS (r=-0.502, P<0.001). CONCLUSION RPS was more common in males and the percentage reduction in pleural effusion on CXR after 2 weeks of treatment was found to be a useful predictor of RPS.

Abstract
STUDY OBJECTIVES To assess the resolution of pleural disease in patients with tuberculous pleurisy (TP) during and after antituberculosis medication. DESIGN An observational, prospective, longitudinal study. SETTING University-affiliated general hospital in Seoul, Korea. PATIENTS AND METHODS Chest radiographs of 85 adult TP patients were followed up prospectively from diagnosis to 24 months after the start of medication. The extent of pleural disease, synonymous with the radiographic term, pleural opacity (PO), was evaluated at regular intervals according to a size scale. Additionally, following completion of 6 months of therapy, residual PO (RPO) was determined by either measurement of the widest width of the opacity, if loculated, or at the superior level of the hemidiaphragm. RESULTS Seventy-seven patients had a PO graded > or = 2 at the initial presentation. At 6, 9, and 24 months, the number of patients with these grades declined. At these time periods, there were 14, 8, and 7 patients, respectively, remaining with this classification. RPO > 10 mm at 24 months was considered indicative of significant residual pleural disease. During the period after 6 months of antituberculosis medication, the number of patients with RPO > or = 10 mm declined from 43 patients at 6 months to 21 patients at 24 months. The presence of loculation on an initial chest decubitus view was associated with significant RPO at 24 months (p = 0.009). CONCLUSION In TP patients, improvement of RPO often occurred even after completion of 6 months of antituberculosis medication up to 24 months. A loculated PO at initial presentation, but not initial PO size, was a predictor of significant RPO at 24 months.

Abstract
Management of patients with tuberculous pleuritis can be improved by establishing early diagnosis accurately, administering effective chemotherapy, and close monitoring of progress for early detection and prompt management of severe pleural inflammation in the hope of preventing or reducing subsequent residual pleural fibrosis. In addition to the conventional diagnostic tools, chemical markers, especially pleural fluid adenosine deaminase and interferon-gamma levels and new microbiological tests such as polymerase chain reaction and BACTEC culture of pleural biopsy specimens for Mycobacterium tuberculosis, can increase the diagnostic yield for tuberculous pleuritis. Indicators of the severity of pleural inflammation, including high pleural fluid tumour necrosis factor-alpha and lysozyme levels, and low pleural fluid glucose and pH, can help to predict residual pleural fibrosis. It is likely that patients will require surgery: (i) complete drainage of pleural fluid for prevention; and (ii) pleurectomy for the treatment of residual pleural fibrosis.

Abstract
The development of pleural fibrosis follows severe pleural space inflammation which is typically associated with an exudative pleural effusion. The response of the mesothelial cell to injury and its ability, along with the basement membrane, to maintain its integrity, is vital in determining whether there is normal healing or pleural fibrosis. The formation of a fibrinous intrapleural matrix is critical to the development of pleural fibrosis. This matrix is the result of disordered fibrin turnover, whereby fibrin formation is up-regulated and fibrin dissolution is down-regulated. Cytokines, such as TGF-beta and TNF-alpha, facilitate the fibrin matrix formation. A complete understanding of the pathogenesis of pleural fibrosis and why abnormal pleural space remodeling occurs in some and not in others, remains unknown. Clinically significant pleural fibrosis requires involvement of the visceral pleura. Isolated parietal pleural fibrosis, as with asbestos pleural plaques, does not cause restriction or respiratory impairment. The causes of visceral pleural fibrosis include asbestos-associated diffuse pleural thickening, coronary bypass graft surgery, pleural infection (including tuberculous pleurisy), drug-induced pleuritis, rheumatoid pleurisy, uraemic pleurisy, and haemothorax. Systemic and intrapleural corticosteroids administered during the initial presentation of rheumatoid pleurisy in small series may decrease the incidence of pleural fibrosis. Several randomised control trials using corticosteroids in tuberculous pleurisy have not shown efficacy in reducing residual pleural fibrosis. Decortication is effective in treating symptomatic patients regardless of the cause of pleural fibrosis as long as chronicity has been documented and significant underlying parenchymal disease has been excluded.

PATIENTS AND METHODS Pleural fluid from 32 TB and 34 non-TB patients was sent for assay of IL-6, TNF-alpha and IFN-gamma. Clinical parameters at presentation and residual pleural scarring at completion of treatment were assessed for pleural TB cases. RESULTS The pleural fluid Levels of IL-6, TNF-alpha and IFN-gamma in TB patients were significantly higher than those with non-TB effusions (P values of <0.001, 0.018 and <0.001, respectively by independent t-test). Utility of these cytokines for diagnosis of pleural TB was evaluated using receiver operating characteristic (ROC) curve analysis. The cut-off values for IL-6, TNF-alpha and IFN-gamma determined in this analysis were 4000, 4 and 60 pg/ml respectively, and their sensitivity and specificity were 90.6% and 76.5%, 90.6% and 79.4%, 100% and 100%, respectively. The pretreatment pleural fluid IL-6 levels had a positive correlation with the number of febrile days after treatment (Pearson correlation test: r=0.60, P=0.009). A negative correlation was found between the percentage reduction in pleural fluid cytokines after 2 weeks treatment and the extent of residual pleural scarring (IL-6: r=-0.62, P=0.041; TNF-alpha: r=-0.65, P=0.030; IFN-gamma: r=0.83, P=0.002). CONCLUSION Pleural fluid IL-6, TNF-alpha and IFN-gamma assays are useful in the diagnosis of pleural TB. The initial IL-6 level correlates with the number of febrile days. The percentage change of cytokines after 2 weeks of treatment also helps to predict residual pleural scarring.

Abstract
STUDY OBJECTIVES To assess the functional sequelae (FS) of patients with tuberculous pleurisy (TP), to analyze the influence of different factors in the occurrence of these FS, and, finally, to evaluate the relationship between the FS and roentgenographic sequelae. DESIGN An observational, retrospective study. SETTING A community teaching hospital in Alicante, Spain. PATIENTS AND METHODS From April 1986 to July 2000, all patients with a firmly established diagnosis of TP, who had been functionally studied at the end of follow-up, were included in the study. A diagnosis of TP was considered to be definitive when the presence of granuloma on a pleural biopsy specimen was demonstrated or when a culture was positive for Mycobacterium tuberculosis in pleural fluid (PF) or tissue. The general characteristics of the study population and PF were compared in patients with or without restrictive FS (ie, FVC or TLC < 80%), looking for risk factors for developing this complication. RESULTS Eighty-one of 150 patients who had been treated for TP were eligible for the study. At the end of follow-up, eight patients (10%) had a restrictive FS. These patients had a lower PF lactate dehydrogenase concentration (p < 0.001), a higher PF concentration of cholesterol (p < 0.03) and triglycerides (p < 0.03), and a higher percentage of lymphocytes (p < 0.04). A weak correlation was found between the FVC and the intensity of radiographic pleural thickening (r = - 0.298; p < 0.01). CONCLUSIONS The FS in patients with TP is restrictive in type, infrequent, and usually mild. A higher PF lipid content or a more chronic inflammatory pleural reaction at diagnosis appear to be risk factors for developing a FS. The correlation between FS and roentgenographic sequelae is poor.

Abstract
1. The aim of the present study was to evaluate the effect of a hyaluronate-based gel (HAbg) on the prevention of pleural thickening and adhesion in tuberculous pleural effusions (TPE). 2. Fifty-two patients who had accumulated a medium or large volume of tuberculous thoracic fluid, fluid being bound by fibre tissues and a pleura thickened more than 2 mm were divided randomly into two groups. All patients were all given standard treatments with antituberculous drugs. The HAbg was injected into the thoracic cavity in the treatment group (n = 27 patients), whereas normal saline was introduced into the thoracic cavity in the control group (n = 25 patients). Before and after HAbg injection, routine thoracic fluid examinations (including qualitative protein analysis, cell counts and classification of cell types) and protein quantification were performed. A chest radiograph and B-ultrasound were performed and pulmonary function was tested after 2 weeks and 3 months of thoracic fluid absorption. 3. The results show that patients who were treated with the HAbg had a significantly thinner pleura, a lower protein concentration and white blood cell count in the thoracic fluid and a higher forced expiratory volume in 1 s and forced vital capacity compared with patients in the control group. 4. Intrathoracic HAbg can prevent pleural thickening and improve lung function in patients who have a large amount of TPE.

Abstract
BACKGROUND To study the factors related to the development of residual pleural thickening in pleural tuberculosis. PATIENTS AND METHODS We studied 39 patients with tuberculous pleural effusion. A chest X-ray was taken of each patient at the end of treatment. The patients' medical histories, pleural fluid findings and diagnostic chest films were evaluated. Residual pleural thickening was defined as thickening that was visibly greater than 2 mm in the lower side portion of the chest film. RESULTS Residual pleural thickening developed in 26% of patients and was found mainly in men (RR = 3.86). In no patients with Löwenstein-Jensen cultures positive for Mycobacterium tuberculosis did pleural complications develop. CONCLUSION Residual pleural thickening is a common complication of tuberculous pleural effusion. Residual pleural thickening in tuberculous pleurisy occurs more often in men and older patients, and in cases in which pleural liquid culture is negative for M. tuberculosis.

Abstract
BACKGROUND TB of the pleura is associated with inflammation and fibrosis. Steroids could reduce the effects of the inflammation, but the immunosuppression could make patients vunerable. OBJECTIVES This review aims to summarise the evidence about the effects of corticosteroids in patients with TB of the pleura, and explores if HIV status is associated with differences in effect estimates. SEARCH STRATEGY We searched the Cochrane Infectious Diseases Group trials register, the Cochrane Library, MEDLINE, and EMBASE. Lists of references from review articles and primary studies were scanned and experts in the field of tuberculosis were contacted. SELECTION CRITERIA Randomised and quasi-randomised trials evaluating the effects of adjunctive corticosteroids in patients diagnosed with TB pleurisy were sought. Both beneficial and adverse effects were noted. DATA COLLECTION AND ANALYSIS Two authors independently applied inclusion criteria, assessed trial quality and extracted the relevant data. MAIN RESULTS Three small trials met the inclusion criteria( total participants n=236), conducted in only HIV negative patients, and with insufficient power to examine death as an outcome. There was no difference in residual lung function between steroid and control groups at completion of treatment. The point estimates for secondary outcomes tended towards benefit with steroids rather than harm, but none were significant; number with pleural fluid (RR 0.28, 95% CI 0.06 to 1.34), number with pleural thickening (RR 0.76, 95% 0.48 to 1.21), and number with pleural adhesions (RR 0.30, 95% CI 0.03 to 2.66). Adverse effects were few and did not result in treatment being discontinued. REVIEWER'S CONCLUSIONS There is insufficient evidence to know whether steroids are effective in tuberculous pleural effusion.

Abstract
STUDY OBJECTIVE Identification of predictive factors for the development of residual pleural thickening (RPT). DESIGN Retrospective study. LOCATION A 1,500-bed tertiary hospital. PATIENTS Patients with pleural tuberculosis diagnosed between December 1991 and February 1995 in our Respiratory Disease Service. INTERVENTIONS The clinical and radiologic characteristics, and measurements of microbiological and biochemical parameters and markers in pleural fluid were studied. RPT was defined in a posteroanterior chest radiograph as a pleural space of >2 mm measured in the lower lateral chest at the level of an imaginary line intersecting the diaphragmatic dome. MEASUREMENTS AND RESULTS In 56 patients studied, 11 (19.6%) had RPT 10 mm and 24 (42.8%) had RPT >2 mm. The pleural fluid of patients with RPT 10 mm had a significantly lower glucose concentration and pH and higher lysozyme and tumor necrosis factor-alpha levels than the other patients. The pleural fluid of patients with RPT >2 mm showed no significant differences. CONCLUSIONS The development of RPT 10 mm was related to higher concentrations of lysozyme and tumor necrosis factor-alpha and lower glucose concentration and pH in pleural fluid compared with development of lower measurements of RPT.
