Tuberculous pericarditis.
Tuberculous pericarditis is a rare but dangerous disease with a mortality of 20% to 40%. Early diagnosis and institution of appropriate therapy are critical, and open pericardial biopsy appears to be the most reliable diagnostic tool. Corticosteroids, in conjunction with antituberculous medication, are effective in suppressing the early granulomatous inflammatory response. Pericardiectomy should be considered early when the response to a medical regimen is delayed or inadequate.

Interventions for treating tuberculous pericarditis.
BACKGROUND: Tuberculous (TB) pericarditis is becoming more common. The infection can result in fluid around the heart, which can be fatal. OBJECTIVES: To evaluate evidence from trials about the effects of medical and surgical treatments for TB pericarditis on death and life-threatening conditions. SEARCH STRATEGY: The Cochrane Infectious Diseases Group trials register, the Cochrane controlled trials register, Medline, Embase and reference lists of articles; contact with experts in the field. SELECTION CRITERIA: Randomised and quasi-randomised trials of treatments for TB pericarditis. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed trial quality and extracted data. Meta-analysis using fixed effects models calculated summary statistics, provided there was no significant heterogeneity, and expressed results as relative risk. MAIN RESULTS: Three trials met the inclusion criteria, with a total of 411 participants. Treatments were adjuvant steroids and surgical drainage. Two small trials tested steroids. There were fewer deaths (all causes) in the intervention group, but the numbers were small and the result could have occurred by chance (relative risk [RR] 0.65, 95% confidence interval [CI] 0.36 to 1.16, n = 350). In one trial studying patients with effusion, "cure" was higher in the steroid group (alive and free of disability at 2 years (RR 0.69, 95% CI 0.29 to 0.80, n = 221). One trial examined open surgical drainage compared with conservative management, and showed no impact of surgery on death, but a protective effective against cadiac tamponade (RR 0.04, 95% CI 0.00 to 0.64). REVIEWER'S CONCLUSIONS: Steroids have potentially large impacts on survival, but trials are too small to test this. We believe further placebo controlled trials of steroids are warranted, exploring whether the presence of effusion or fibrosis modifies effects. Surgical options also require further evaluation.

Predictors of constrictive pericarditis after tuberculous pericarditis.
OBJECTIVE: To identify features which predict the subsequent development of constrictive pericarditis from acute or subacute tuberculous (TB) pericarditis. SETTING: Tertiary referral centre, chest hospital. PATIENTS: The records of 16 consecutive patients in whom acute or subacute TB pericarditis was diagnosed between 1988 and 1990 at a chest hospital were reviewed. These records included a follow up of at least 12 months. RESULTS: During a follow up of 14.2 (12-30) months, 8 patients had constrictive pericarditis diagnosed by cardiac catheterisation or by inspection at the time of operation (group A). There was no evidence of constriction in the other eight patients (group B). There was no significant difference between the two groups in the type or duration of symptoms of TB pericarditis before admission or the volume and characteristics of pericardial fluid obtained at hospital admission. Clinical features of cardiac tamponade on admission correlated closely with the subsequent development of constrictive pericarditis requiring pericardectomy (7/8 v 2/8; P = 0.01), despite the fact that the signs of tamponade resolved completely after pericardiocentesis. CONCLUSION: The findings suggest that cardiac tamponade in the early clinical stage of TB pericarditis is the most predictive factor of subsequent constrictive pericarditis. The degree of fibrosis of pericardium when treatment starts may be the most important determinant of whether or not constriction develops.

Constrictive pericarditis in patients with tuberculous pericarditis.
Constrictive pericarditis is a complication of tuberculous pericarditis that necessitates surgical intervention. In this study, we sought to identify echocardiographic features that could predict the development of constrictive pericarditis from acute or subacute pericarditis. From January 1988 through May 1998, all patients with a discharge diagnosis of tuberculous pericarditis were enrolled in the study, and their clinical features, laboratory findings, sonographic images, treatments, and outcomes were analyzed. Tuberculous pericarditis was demonstrated on the basis of positive Mycobacterium tuberculosis cultures from pericardial fluid or tissue in 11 patients; pericardial biopsy specimens demonstrating caseating granulomas in seven; and bacteriologic or histologic evidence of active extra-pericardial tuberculosis in conjunction with major pericardial effusion in four. Seventeen patients had effusive tuberculous pericarditis and five had constrictive tuberculous pericarditis as the initial diagnosis. The echocardiographic findings of effusive pericarditis were classified as shaggy-type effusion (n = 8) and non-shaggy-type effusion (9). Shaggy effusion was defined as the presence of multiple fibrin strands or a mass-like exudate coating the pericardium and bridging the pericardial effusion. Non-shaggy effusion was characterized by an anechoic pericardial space with or without a thickened pericardium, but no shaggy exudative coating. The mean duration between the onset of symptoms and diagnosis was longer in patients with shaggy-type effusion (39.6 +/- 8.7 vs 21.0 +/- 13.9 days, p < 0.05). Prednisolone (20-30 mg/d) was used in addition to antituberculous chemotherapy in 11 of the 17 patients with effusive pericarditis. Two of 11 patients (18%) who received steroid therapy, and five of the six patients (83%) who did not, developed constrictive pericarditis in the following year. Therefore, we concluded that adjuvant therapy with steroids significantly decreased the risk of constrictive pericarditis in patients with non-shaggy, but not shaggy, effusion.

The detection of IgG against a specific mycobacterial antigen (A60) in the diagnosis of tuberculous pericarditis.
Diagnosis of tuberculous pericarditis (TP) is often difficult with standard methods, while prompt recognition of this disease may affect its prognosis. We report a case of tuberculous pericarditis, in which the presumptive diagnosis was obtained by detection of specific immunoglobulin G (IgG) against A60 antigen, the main thermostable component of purified protein derivative (PPD). Serological diagnosis may be a useful approach in the screening of the aetiology of pericarditis.

The diagnostic and prognostic value of adenosine deaminase in tuberculous pericarditis.
Because of the difficulty in isolating the causative organism, pericardial tuberculosis is rarely diagnosed. Adenosine deaminase activity measured in the pericardial fluid of 108 patients was initially of undetermined origin. Subsequently, we classified five sources: (1) tuberculosis (20 cases); (2) idiopathy (82 cases); (3) neoplasia (three cases); (4) purulent bacterial infection (two cases); and (5) radiotherapy (one case). The highest mean adenosine deaminase value (126 +/- 16.68 U.l(-1) was found in group 1; other values were 29.4 +/- 8.9, 27 +/- 7.21, 29.5 +/- 13.4, 26 U.l(-1) in the idiopathy, neoplasia, purulent bacterial infection and radiotherapy groups, respectively. there was a statistically significant difference between group 1 and the other groups (P less than 0.001), indicating that the adenosine deaminase value has 100% sensitivity and 91% specificity. In addition, there was a positive correlation between high adenosine deaminase values and the development of constrictive pericarditis. In this study, two patients required pericardectomy. Therefore, the adenosine deaminase value is a significant prognostic indicator for the development of constrictive pericarditis in tuberculous pericarditis.

Tuberculous pericarditis.
BACKGROUND: The incidence of tuberculous pericarditis is increasing in Africa as a result of the human immunodeficiency virus (HIV) epidemic. The primary objective of this article was to review and summarize the literature on the pathogenesis, diagnosis, and management of tuberculous pericarditis. METHODS AND RESULTS: We searched MEDLINE (January 1966 to May 2005) and the Cochrane Library (Issue 1, 2005) for information on relevant references. A "definite" diagnosis of tuberculous pericarditis is based on the demonstration of tubercle bacilli in pericardial fluid or on a histological section of the pericardium; "probable" tuberculous pericarditis is based on the proof of tuberculosis elsewhere in a patient with otherwise unexplained pericarditis, a lymphocytic pericardial exudate with elevated adenosine deaminase levels, and/or appropriate response to a trial of antituberculosis chemotherapy. Treatment consists of the standard 4-drug antituberculosis regimen for 6 months. It is uncertain whether adjunctive corticosteroids are effective in reducing mortality or progression to constriction. Surgical resection of the pericardium remains the appropriate treatment for constrictive pericarditis. The timing of surgical intervention is controversial, but many experts recommend a trial of medical therapy for noncalcific pericardial constriction, and pericardiectomy in nonresponders after 4 to 8 weeks of antituberculosis chemotherapy. CONCLUSIONS: Research is needed to improve the diagnosis, assess the effectiveness of adjunctive steroids, and determine the impact of HIV infection on the outcome of tuberculous pericarditis.

Diagnosing tuberculous pericarditis.
BACKGROUND: Definitive diagnosis of tuberculous pericarditis requires isolation of the tubercle bacillus from pericardial fluid, but isolating the organism is often difficult. AIM: To improve diagnostic efficiency for tuberculous pericarditis, using available tests. DESIGN: Prospective observational study. METHODS: Consecutive patients (n = 233) presenting with pericardial effusions underwent a predetermined diagnostic work-up. This included (i) clinical examination; (ii) pericardial fluid tests: biochemistry, microbiology, cytology, differential white blood cell (WBC) count, gamma interferon (IFN-gamma), adenosine deaminase (ADA) levels, polymerase chain reaction testing for Mycobacterium tuberculosis; (iii) HIV; (iv) sputum smear and culture; (v) blood biochemistry; and (vi) differential WBC count. A model was developed using 'classification and regression tree' analysis. The cut-off for the total diagnostic index (DI) was optimized using receiver operating characteristic (ROC) curves. RESULTS: Fever, night sweats, weight loss, serum globulin (>40 g/l) and peripheral blood leukocyte count (<10 x 10(9)/l) were independently predictive. The derived prediction model had 86% sensitivity and 84% specificity when applied to the study population. Pericardial fluid IFN-gamma >or=50 pg/ml, concentration had 92% sensitivity, 100% specificity and a positive predictive value (PPV) of 100% for the diagnosis of tuberculous pericarditis; pericardial fluid ADA >or=40 U/l had 87% sensitivity and 89% specificity. A diagnostic model including pericardial ADA, lymphocyte/neutrophil ratio, peripheral leukocyte count and HIV status had 96% sensitivity and 97% specificity; substituting pericardial IFN-gamma for ADA yielded 98% sensitivity and 100% specificity. DISCUSSION: Basic clinical and laboratory features can aid the diagnosis of tuberculous pericarditis. If available, pericardial IFN-gamma is the most useful diagnostic test. Otherwise we propose a prediction model that incorporates pericardial ADA and differential WBC counts.

Recent experience with tuberculous pericarditis.
Twelve patients with tuberculous pericarditis were found among 1,194 patients with tuberculosis treated at the University of Texas Medical Branch over a 10-year period, an incidence of 1%. Surgical treatment was undertaken in 4 patients, and the rest were treated medically. The surgically treated patients had no major complications, and none of them died. In the medically treated group, however, 1 patient died, 1 had an anaerobic empyema, and 1 experienced respiratory arrest. In addition, the average hospital stay was 33 days less in the surgically treated group. Early surgical intervention should be carried out in patients with tuberculous pericarditis who do not respond promptly to adequate antituberculosis chemotherapy.

[A case of tuberculous pericarditis].
A case of tuberculous pericarditis successfully managed with medical treatment alone was reported. A 78-year-old male was admitted because of cough, dyspnea and fever. Chest X-P and echocardiogram revealed massive pericardial effusion. His clinical symptoms and signs suggested cardiac tamponade. Mycobacterium tuberculosis was detected from pericardial fluid. ADA activity in pericardial fluid was high. Thoracic CT scan showed tracheobronchial, pretracheal, paratracheal and superior mediastinal lymph-node swelling. The diagnosis of tuberculous pericarditis was confirmed. Anti-tuberculous therapy consisting of INH, RFP, EB in combination with prednisolone was started. One month later pericardial effusion was controlled and six months later he was in good clinical condition without surgical treatment.

[Tuberculous pericarditis].
A case of specific tuberculous pericarditis is described. A short clinical and etiological classification of pericarditis is given. There are so many new forms of pericarditis today, like autoimmune, postirradiation, drug induced, etc. Specific tuberculous pericarditis is rarely registered today. One must intend to specify TB pericarditis almost if pericardial effusion is present. Pericardial punction is of much help in the diagnosis and treatment of pericardial effusion. Steroid therapy is very important in prevention of forming pericardial adhesions.

Tuberculous pericarditis: MRI features with contrast enhancement.
Tuberculous pericarditis has decreased in incidence, but early diagnosis and treatment are critical because constrictive pericarditis is a serious complication of this condition. The appearances of tuberculous pericarditis on gadolinium enhanced magnetic resonance imaging are described and the value of this modality in achieving an early diagnosis is emphasized.

Clinical characteristics and initial management of patients with tuberculous pericarditis in the HIV era: the Investigation of the Management of Pericarditis in Africa (IMPI Africa) registry.
BACKGROUND: The incidence of tuberculous pericarditis has increased in Africa as a result of the human immunodeficiency virus (HIV) epidemic. However, the effect of HIV co-infection on clinical features and prognosis in tuberculous pericarditis is not well characterised. We have used baseline data of the Investigation of the Management of Pericarditis in Africa (IMPI Africa) registry to assess the impact of HIV co-infection on clinical presentation, diagnostic evaluation, and treatment of patients with suspected tuberculous pericarditis in sub-Saharan Africa. METHODS: Consecutive adult patients in 15 hospitals in three countries in sub-Saharan Africa were recruited on commencement of treatment for tuberculous pericarditis, following informed consent. We recorded demographic, clinical, diagnostic and therapeutic information at baseline, and have used the chi-square test and analysis of variance to assess probabilities of significant differences (in these variables) between groups defined by HIV status. RESULTS: A total of 185 patients were enrolled from 01 March 2004 to 31 October 2004, 147 (79.5%) of whom had effusive, 28 (15.1%) effusive-constrictive, and 10 (5.4%) constrictive or acute dry pericarditis. Seventy-four (40%) had clinical features of HIV infection. Patients with clinical HIV disease were more likely to present with dyspnoea (odds ratio [OR] 3.2, 95% confidence interval [CI] 1.4 to 7.4, P = 0.005) and electrocardiographic features of myopericarditis (OR 2.8, 95% CI 1.1 to 6.9, P = 0.03). In addition to electrocardiographic features of myopericarditis, a positive HIV serological status was associated with greater cardiomegaly (OR 3.89, 95% CI 1.34 to 11.32, P = 0.01) and haemodynamic instability (OR 9.68, 95% CI 2.09 to 44.80, P = 0.0008). However, stage of pericardial disease at diagnosis and use of diagnostic tests were not related to clinical HIV status. Similar results were obtained for serological HIV status. Most patients were treated on clinical grounds, with microbiological evidence of tuberculosis obtained in only 13 (7.0%) patients. Adjunctive corticosteroids were used in 109 (58.9%) patients, with patients having clinical HIV disease less likely to be put on them (OR 0.37, 95% CI 0.20 to 0.68). Seven patients were on antiretroviral drugs. CONCLUSION: Patients with suspected tuberculous pericarditis and HIV infection in Africa have greater evidence of myopericarditis, dyspnoea, and haemodynamic instability. These findings, if confirmed in other studies, may suggest more intensive management of the cardiac disease is warranted in patients with HIV-associated pericardial disease.

A late complication of tuberculous pericarditis after partial pericardial resection.
Tuberculous pericarditis is estimated to occur in 1% to 2% of cases of pulmonary tuberculosis. Despite adequate therapy, a subset of patients may eventually require pericardiectomy. Incomplete pericardial resections are associated with an increased incidence of late complications. We report a cutaneous sinus tract communicating with residual pericardium and a retrosternal abscess cavity 11 years after partial pericardial resection.

[Echocardiography in a case of acute tuberculous pericarditis which progressed to constrictive pericarditis].
A case of acute tuberculous pericarditis with massive pericardial effusion progressed to constrictive pericarditis under echocardiographic observation during one year. This 59-year-old man was hospitalized because of dyspnea. On admission, his physical examination revealed a paradoxical pulse, engorged jugular veins, hepatomegaly, and pitting edema in the pretibial regions. Chest radiography revealed an enlarged cardiac silhouette and a marked left pleural effusion. His echocardiogram showed a massive pericardial effusion. A biatrial echogram recorded by esophageal echocardiography showed a massive pericardial effusion anterior to the right atrial free wall. Echocardiography performed four months after commencing therapy revealed a reduction in the pericardial effusion, and normal motion of the interventricular septum and posterior wall. However, the motion of the interatrial septum was already abnormal and the excursion of the right atrial free wall was markedly reduced. These finding were similar to those in constrictive pericarditis, as previously reported. Eleven months after admission, both conventional and esophageal echograms showed findings typical of constrictive pericarditis. Thus, in this case, the abnormal biatrial dynamics were recognized earlier than the abnormal left ventricular wall motion.

Management of tuberculous pericarditis.
The cases of 17 patients with tuberculous pericarditis were reviewed. Thirteen patients had effusive pericarditis, and 10 had surgical drainage of the effusion. No deaths were due to pericardial tamponade; this appears to be related to earlier recognition of major pericardial effusions by echocardiography. In 2 patients clinical evidence of pericardial constriction developed while they were on a regimen of therapy, and in another 2 patients, echocardiography revealed pericardial thickening after resolution of the effusion. A pericardial window is recommended for the short-term management of patients suspected of having tuberculous pericarditis with a major pericardial effusion by echocardiography. If a thickened pericardium is found during the window procedure, early pericardiectomy is strongly encouraged.
