RESUMEN
ABSTRACT: Our objective was to identify independent risk factors for predicting which patients in the Chinese population would likely develop respiratory failure.A descriptive analysis was conducted of demographic and clinical data of patients with tuberculous empyema (TE) admitted to the Beijing Chest Hospital, Capital Medical University between January 2001 and January 2020. Risk factors associated with postsurgical respiratory failure in TE patients were identified based on results of analyses based on univariable and multivariable logistic regression models.A total of 139 TE patients who underwent surgical treatment in the Beijing Chest Hospital, Capital Medical University from January 2001 to January 2020 were enrolled in this study. Cases included 109 male and 30 female patients, with an overall mean age (range 17-73) of 39.3âyears. Of 139 TE patients, 26 (18.7%) experienced respiratory failure after surgery. Among significant risk factors for postsurgical respiratory failure, intraoperative blood loss volume greater than 1000âmL had the highest odds ratio value of 6.452. In addition, a pathologic preoperative pulmonary function test result showing a high partial pressure of carbon dioxide level was an independent risk factor for respiratory failure. Moreover, the presence of tuberculosis lesions in the contralateral lung was another significant risk factor for respiratory failure, as determined using multivariate analysis.Respiratory failure is a predominant complication experienced by TE patients undergoing surgery. High intraoperative blood loss, high preoperative high partial pressure of carbon dioxide level, and tuberculosis lesion(s) in the contralateral lung of TE patients were associated with increased risk of postoperative respiratory failure.

We present a case of pleural effusion with encapsulation that was observed in the right thorax of a patient. PCR analysis of the patient's pleural effusion showed positivity for Mycobacterium tuberculosis. After six months, his chest CT showed the development of niveau and pulmonary consolidation. We definitively diagnosed him as having chronic pulmonary tuberculosis with tuberculous empyema drainage. At the time of his hospital admission, his serum carcinoembryonic antigen (CEA) level was elevated. After we started treatment using antituberculosis drugs, the infiltration shadow in his lung fields disappeared, and the serum CEA level decreased. The results suggest that the serum CEA level reflects the extent of the development of pulmonary tuberculosis lesions.

Tuberculous (TB) pleurisy and parapneumonic effusion (PPE) are common causes of pleural fibrosis. The mechanisms underlying fibrin deposition may be different since involved inflammatory cells are distinct. In this study, we measured various cytokines and fibrinolytic enzymes and compared the differences between the two effusions. PPE was further divided into noncomplicated PPE and complicated PPE/empyema subgroups. Tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, IL-6, IL-8, macrophage inflammatory protein (MIP)-1beta, monocyte chemoattractant protein (MCP)-1, plasminogen activator inhibitor type 1 (PAI-1) and tissue type plasminogen activator (tPA) were measured using enzyme-linked immunosorbent assays. Significantly higher values of PAI-1, PAI-1/tPA ratio, IL-1beta, IL-8 and MIP-1beta and significantly lower values of TNF-alpha, IL-6 and MCP-1 were observed in PPE/empyema than in TB effusions. Compared to noncomplicated PPE, complicated PPE/empyema had significantly higher levels of TNF-alpha, IL-1beta, IL-8 and MIP-1beta. TB pleurisy patients who had higher effusion levels of TNF-alpha, IL-1beta and IL-8 were predisposing to residual pleural thickening. The underlying mechanisms of fibrin formation and deposition between the two effusions studied (PPE/empyema and TB pleurisy) could not be fully explained by the results of the present study. More studies are needed to explore this further.
