    Interventions for treating tuberculous pericarditis
    (John Wiley & Sons, Ltd. on behalf of The Cochrane Collaboration, 2017) Wiysonge, Charles S.; Ntsekhe, Mpiko; Thabane, Lehana; Volmink, Jimmy; Majombozi, Dumisani; Gumedze, Freedom; Pandie, Shaheen; Mayosi, Bongani M.
    Background: Tuberculous pericarditis – tuberculosis infection of the pericardial membrane (pericardium) covering the heart – is becoming more common. The infection can result in fluid around the heart or fibrosis of the pericardium, which can be fatal. Objectives: In people with tuberculous pericarditis, to evaluate the effects on death, life‐threatening conditions, and persistent disability of: 1. 6‐month antituberculous drug regimens compared with regimens of 9 months or more; 2. corticosteroids; 3. pericardial drainage; and 4. pericardiectomy. Search methods: We searched the Cochrane Infectious Diseases Group trials register (January 2005); the Cochrane Controlled Trials Register (Issue 4, 2004); MEDLINE (1966 to January 2005); EMBASE (1980 to January 2005); and checked the reference lists of existing reviews. We also contacted organizations and individuals working in the field. Selection criteria: Randomized and quasi‐randomized controlled trials of treatments for tuberculous 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 statistically significant heterogeneity, and expressed results as risk ratio. Study authors were contacted for additional information. Main results: Four trials met the inclusion criteria, with a total of 469 participants. Treatments tested were adjuvant steroids and surgical drainage. Two trials with a total of 383 participants tested adjuvant steroids in participants with suspected tuberculous pericarditis in the pre‐HIV era. Fewer participants died in the intervention group, but numbers were small (risk ratio [RR] 0.65; 95% confidence interval [CI] 0.36 to 1.16, n = 350). One small trial tested steroids in HIV positive participants with effusion showed a similar pattern (RR 0.50; 95% CI 0.19 to 1.28, n = 58). One trial examined open surgical drainage compared with conservative management, and showed surgery relieved cardiac tamponade. Authors' conclusions: Steroids could have important clinical benefits, but the trials published to date are too small to demonstrate an effect. This requires large placebo controlled trials. Subgroup analysis could explore whether effusion or fibrosis modify the effects. Therapeutic pericardiocentesis under local anaesthesia and pericardiectomy also require further evaluation.
