The optimal duration of anti-tuberculous therapy before pericardiectomy in constrictive tuberculous pericarditis

Background It is unclear about the duration of anti-tuberculous therapy before pericardiectomy (DATT) in the patients with constrictive tuberculous pericarditis. This study aims to explore the optimal DATT and its impact on surgical outcomes in these patients. Methods We retrospectively enrolled 93 patients with constrictive tuberculous pericarditis undergoing pericardiectomy and divided them into two groups according to the optimal cutoff value of DATT which was determined by the receiver operating characteristic (ROC) curve and Youden Index. Postoperative and survival outcomes were compared between the two groups. Results The optimal cutoff value of DATT was 1.05 (months). The enrolled patients were divided into the DATT ≤ 1.05 group and the DATT > 1.05 group, with 24 (25.8%) and 69 (74.2%) cases, respectively. Comparing with the DATT ≤ 1.05 group, the DATT > 1.05 group had shorter postoperative ICU stay (P = 0.023), duration of chest drainage (P = 0.002), postoperative hospital stay (P = 0.001) and lower incidence of postoperative complications (P < 0.001). There were no statistical differences between the two groups in recurrence and survival outcomes. Conclusions It would be of potential benefit to enhance recovery after pericardiectomy if DATT lasted for at least 1 month in the patients with constrictive tuberculous pericarditis.

Diagnostic accuracy of the Xpert MTB/RIF assay for tuberculous pericarditis: A systematic review and meta-analysis

Objective The purpose of this study was to evaluate the diagnostic efficacy of Xpert MTB/RIF for tuberculous pericarditis (TBP). Methods We searched relevant databases for Xpert MTB/RIF for TBP diagnosis until April 2021 and screened eligible studies for study inclusion. We evaluated the effectiveness of Xpert MTB/RIF when the composite reference standard (CRS) and mycobacterial culture were the gold standards, respectively. We performed meta-analyses using a bivariate random-effects model, and when the heterogeneity was obvious, the source of heterogeneity was further discussed. Results We included seven independent studies comparing Xpert MTB/RIF with the CRS and six studies comparing it with culture. The pooled sensitivity, specificity, and area under the curve of Xpert MTB/RIF were 65% (95% confidence interval, 59–72%), 99% (97–100%), and 0.99 (0.97–0.99) as compared with the CRS, respectively, and 75% (53–88%), 99% (90–100%), and 0.94 (0.92–0.96) as compared with culture, respectively. There was no significant heterogeneity between studies when CRS was the gold standard, whereas heterogeneity was evident when culture was the gold standard. Conclusions The sensitivity of Xpert MTB/RIF for diagnosing TBP was moderate and the specificity was good; thus, Xpert MTB/RIF can be used in the initial diagnosis of TBP.

Inheritance vs. infectivity as a mechanism of malady and death of Frederic Chopin

Based on a macroscopic analysis of the heart of Frederic Chopin performed in 2014, it can be stated with high probability that the composer suffered from a long lasting tuberculosis as a primary disease, which was the cause of progressive deterioration of his physical condition and numerous symptoms mainly from the respiratory tract. Tuberculous pericarditis rapidly progressing within a rather short period of time, a relatively rare complication of diffuse tuberculosis, might have been an immediate cause of death. This would aptly coincide with a startling opinion that in an autopsy picture the composer’s heart had been more affected by the disease than the lungs.

A Case of Crohn’s Disease with Cardiac Tamponade Caused by Tuberculous Pericarditis: Assessment of a Rare Phenomenon

A 28-year-old woman was hospitalized for cardiac tamponade caused by tuberculous pericarditis. She was taking ustekinumab (UST) for Crohn’s disease. UST is not considered to significantly increase the risk of developing serious infections, including tuberculosis. However, there is still a risk of Mycobacterium tuberculosis reactivation. Therefore, for patients on concurrent UST and antituberculosis medication, a close collaboration among specialists in infectious diseases, cardiology, and gastroenterology is necessary.

Diagnostic accuracy of the Xpert MTB/RIF assay for tuberculous pericarditis: A protocol of systematic review and meta-analysis

Background Tuberculous pericarditis (TBP) can lead to serious consequences. Early diagnosis and treatment are very important for TBP, but early diagnosis is still very challenging. This study aims to evaluate the diagnostic accuracy of Xpert MTB/RIF for TBP using meta-analysis method. Methods We will search Embase, PubMed, the Cochrane Library, China National Knowledge Infrastructure (CNKI), and the Wanfang database for researches assessing the diagnostic accuracy of Xpert MTB/RIF for TBP until April 2021. Any types of study design with full text will be selected and included. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool will be used to assess the risk of bias. We will use version 15.0 of the STATA software with the midas command packages to carry out meta-analyses. Results Evidence for diagnostic accuracy of Xpert MTB/RIF for TBP will be provided through the study, and this protocol will be submitted to a peer-reviewed journal for publication. Conclusion This study will provide evidence of Xpert MTB/RIF for TBP.

Penggunaan Kortikosteroid pada Pasien Anak dengan Perikarditis Tuberkulosis.

Tuberculous pericarditis (TB pericarditis) is a disease that still frequently occurs in developing countries. The mortality rate due to TB pericarditis is still quite high, reaching 17-40%. Death due to tuberculous pericarditis is influenced by adequate or not treatment. The use of additional corticosteroid therapy is still a matter of debate in the treatment of tuberculous pericarditis. Writing this case aims to see the outcome of the use of corticosteroids in patients with tuberculous pericarditis. Literature searches were carried out through Pubmed and Google Scholar. From the results of literature search, two meta-analyzes were obtained that discussed the use of corticosteroids in tuberculous pericarditis. In children with tuberculous pericarditis, the use of corticosteroids does not reduce mortality, but can reduce complications due to tuberculous pericarditis. Keywords: corticosteroids, tuberculous pericarditis, outcome.

Pericardial calcification with plain radiographic features of tuberculosis in a child: incidental finding and a case report

Tuberculous pericarditis is frequently reported as the primary cause of pericardial calcification and occurs in about 1-2% of individuals with pulmonary tuberculosis, this however is a rare finding in the Western world. This is a 12-year-old male child that was referred from a peripheral health care center for plain radiograph of the chest on account of cough, easy fatiguability, night sweats, loss of weight, loss of appetite and dyspnea most times on excersion for more than a month duration. The plain chest radiograph demonstrated normal cardiac size with a cardiothoracic ratio of about 55/120, there is circumferential radio-opacity of calcic density around the peripheral walls of the heart; the pericardial calcification. The vascular pedicle appears slightly widened. The lung fields show extensive streaky opacities with cystic lung changes bilaterally more marked on the left lung field where consolidation, loss of lung volume and pleural effusion are also demonstrated. A two-dimensional echocardiography showed mild-moderate pericardial effusion, thickening of both visceral and parietal pericardium, and echogenic fond-like structures protruding in to the pericardial cavity. A diagnosis of pulmonary tuberculosis with features of tuberculous pericarditis in a 12-year-old male child was established. The patient has been placed on anti-tuberculous drugs, hematinic, and parents advised on good and adequate diet with adequate rehydration and strict drug compliance. Screening of the siblings and members of the family with close contact have also been emphasized. We report the radiographic features of pulmonary tuberculosis and pericardial calcification in a 12-year-old male child due to its peculiar presentation.
