Pan Afr Med J 2024; 47:54. [PMID: 38646137 PMCID: PMC11032075 DOI: 10.11604/pamj.2024.47.54.15439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2018] [Accepted: 01/24/2024] [Indexed: 04/23/2024] Open
Abstract
Our study aimed to assess the benefit of intrapleural fibrinolysis before resorting to surgery to treat complicated parapneumonic effusion and empyema. We conducted a retrospective and descriptive study, including all patients hospitalized in the intensive care unit (ICU) of the Abderhaman Mami hospital, Tunisia for empyema treated with instillation of intrapleural fibrinolytic therapy between the 1st January 2000 and 31st December 2016. In all patients, empyema was diagnosed on clinical features, imaging findings (chest X-ray, thoracic echography and/or computed tomography (CT), and microbiological data. The fibrinolytic agent used was streptokinase. The efficiency of intrapleural fibrinolytic therapy was judged on clinical and paraclinical results. Among 103 cases of complicated parapneumonic effusion and empyema, 34 patients were included. The mean age was 34 years [15-81] with a male predominance (sex ratio at 2.77). Median APACH II score was 9. Fifty (50%) of the patients (n=17) had no past medical history; addictive behavior was described in 17 patients (50%). All patients were admitted for acute respiratory failure and one patient for septic shock. Pleural effusion was bilateral in 7 patients. Bacteria isolated were Streptococcus pneumonia (6 cases), Staphylococcus aureus (3 cases, including one which methicillin-resistant), Staphylococcus epidermidis (1 case), anaerobes (5 cases), and Klebsiella pneumoniae (1 case). First-line antimicrobial drug therapy was amoxicillin-clavulanate in 20 patients. A chest drain was placed in all cases in the first 38 hours of ICU admission. The median number of fibrinolysis sessions was 4 [2-9] and the median term of drainage was 7 days [3-16]. No side effects were observed. Video-assisted thoracoscopic surgery was proposed in 5 patients. The median length of hospitalization stay was 15 days [6-31]. One patient died due to multi-organ failure.

BMC Pulm Med 2023; 23:355. [PMID: 37730573 PMCID: PMC10512587 DOI: 10.1186/s12890-023-02649-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Accepted: 09/11/2023] [Indexed: 09/22/2023] Open
Abstract
BACKGROUND Community-acquired pneumonia (CAP) patients usually present with parapneumonic pleural effusion (PPE), which complicates the treatment of pneumonia. This study aims to investigate the clinical characteristics and risk factors of elderly CAP patients hospitalised with PPE. METHODS The clinical data of 132 elderly patients with CAP were retrospectively analysed. A total of 54 patients with PPE (PPE group) and 78 patients without PPE (NPPE group) were included in this study. Clinical data, laboratory examinations, treatments and other relevant indicators were collected. Univariate analysis and multivariate logistic regression analysis will be used to explore the possible risk factors for PPE. RESULTS The proportion of PPE in elderly patients with CAP was 40.9%. PPE patients were significantly more likely to be older, have comorbid neurological diseases, experience chest tightness, and have a lasting fever (P < 0.05). In contrast to NPPE patients, the total number of lymphocytes, serum albumin and blood sodium levels in the PPE group were significantly lower (P < 0.05). The blood D-dimer, C-reactive protein and CURB-65 score of PPE patients were significantly higher (P < 0.05) than those of NPPE patients. Multivariate logistic regression identified chest tightness (OR = 3.964, 95% CI: 1.254-12.537, P = 0.019), long duration of fever (OR = 1.108, 95%CI: 1.009-1.217, P = 0.03), low serum albumin (OR = 0.876, 95%CI: 0.790- 0.971, P = 0.012) or low blood sodium (OR = 0.896, 95%CI: 0.828-0.969, P = 0.006) as independently associated with the development of parapneumonic pleural effusion in the elderly. CONCLUSION This study has identified several clinical factors, such as chest tightness, long duration of fever, low serum albumin, and low blood sodium, as risk factors for the development of pleural effusion in elderly patients with CAP. Early identification and prompt management of these patients can prevent inappropriate treatment and reduce morbidity and mortality.

Abstract
OBJECTIVES Compare the use of Tissue Plasminogen Activator (t-PA) and t-PA + Dornase (DNase) for the management of complicated pleural effusions, and to determine if a dose-response relationship exists for t-PA. METHODS Retrospective cohort study that examined all adult patients at a large academic medical center who received intrapleural t-PA or t-PA + DNase for the management of a complicated pleural effusions. Outcomes were success of therapy [defined as avoidance of secondary interventions (i.e. VATSD or thoracotomy)], chest tube output pre- and post-administration, radiographic findings, t-PA dose and frequency, and bleeding complications. RESULTS Thirty-five patients were enrolled: 25 received t-PA and 10 received t-PA + DNase. Successful pharmacologic treatment occurred in 88% of patients receiving t-PA and 100% of patients receiving t-PA + DNase (p = 0.54). In the t-PA group, chest tube output increased from 75 ml/12 h to 538 ml/12 h after administration of t-PA (p = 0.001), and from 103 ml/12 h to 502 ml/12 h (p = 0.001) in the t-PA + DNase group. Radiographic improvement occurred in 84% of t-PA patients and 90% of t-PA + DNase patients (p = 0.99). In the t-PA group, a successful response occurred in 92% of patients receiving a cumulative dose of ≤10 mg (n = 13) and 83% of patients receiving a cumulative dose of >10 mg (n = 12), p = 0.43. Patients who received a single t-PA dose compared to those who received multiple doses also had similar success rates (p = 1). There was one instance of bleeding following drug administration. CONCLUSION Both t-PA and t-PA + DNase were highly effective for reducing a patient's need for surgical intervention. Higher cumulative doses or more frequency administrations did not appear to provide additional benefit.

Abstract
Blood and fluid analysis is extensively used for classifying the etiology of pleural effusion. However, most studies focused on determining the presence of a disease. This study classified pleural effusion etiology employing deep learning models by applying contrastive-loss. Patients with pleural effusion who underwent thoracentesis between 2009 and 2019 at the Asan Medical Center were analyzed. Five different models for categorizing the etiology of pleural effusion were compared. The performance metrics were top-1 accuracy, top-2 accuracy, and micro-and weighted-AUROC. UMAP and t-SNE were used to visualize the contrastive-loss model’s embedding space. Although the 5 models displayed similar performance in the validation set, the contrastive-loss model showed the highest accuracy in the extra-validation set. Additionally, the accuracy and micro-AUROC of the contrastive-loss model were 81.7% and 0.942 in the validation set, and 66.2% and 0.867 in the extra-validation set. Furthermore, the embedding space visualization in the contrastive-loss model exhibited typical and atypical effusion results by comparing the true and false positives of the rule-based criteria. Therefore, classifying the etiology of pleural effusion was achievable using the contrastive-loss model. Conclusively, visualization of the contrastive-loss model will provide clinicians with valuable insights for etiology diagnosis by differentiating between typical and atypical disease types.

Abstract
Empyema, a severe complication of pneumonia, trauma, and surgery is characterized by fibrinopurulent effusions and loculations that can result in lung restriction and resistance to drainage. For decades, efforts have been focused on finding a universal treatment that could be applied to all patients with practice recommendations varying between intrapleural fibrinolytic therapy (IPFT) and surgical drainage. However, despite medical advances, the incidence of empyema has increased, suggesting a gap in our understanding of the pathophysiology of this disease and insufficient crosstalk between clinical practice and preclinical research, which slows the development of innovative, personalized therapies. The recent trend towards less invasive treatments in advanced stage empyema opens new opportunities for pharmacological interventions. Its remarkable efficacy in pediatric empyema makes IPFT the first line treatment. Unfortunately, treatment approaches used in pediatrics cannot be extrapolated to empyema in adults, where there is a high level of failure in IPFT when treating advanced stage disease. The risk of bleeding complications and lack of effective low dose IPFT for patients with contraindications to surgery (up to 30%) promote a debate regarding the choice of fibrinolysin, its dosage and schedule. These challenges, which together with a lack of point of care diagnostics to personalize treatment of empyema, contribute to high (up to 20%) mortality in empyema in adults and should be addressed preclinically using validated animal models. Modern preclinical studies are delivering innovative solutions for evaluation and treatment of empyema in clinical practice: low dose, targeted treatments, novel biomarkers to predict IPFT success or failure, novel delivery methods such as encapsulating fibrinolysin in echogenic liposomal carriers to increase the half-life of plasminogen activator. Translational research focused on understanding the pathophysiological mechanisms that control 1) the transition from acute to advanced-stage, chronic empyema, and 2) differences in outcomes of IPFT between pediatric and adult patients, will identify new molecular targets in empyema. We believe that seamless bidirectional communication between those working at the bedside and the bench would result in novel personalized approaches to improve pharmacological treatment outcomes, thus widening the window for use of IPFT in adult patients with advanced stage empyema.

Abstract
Intrapleural thrombolytics have shown promising results in complicated parapneumonic pleural effusions reducing the need for surgical interventions. Until now, studies have evaluated primarily streptokinase, urokinase, and recently, alteplase. In this case series, we share our experience with tenecteplase-a tissue-specific plasminogen activator in 15 patients. We observed that tenecteplase is effective in 14/15 (93.3%) of our patients, and none of them had any bleeding episodes.

Abstract
Disorders of the pleural space are quite common in the critically ill patient. They are generally associated with the underlying illness. It is sometimes difficult to assess for pleural space disorders in the ICU given the instability of some patients. Although the portable chest X-ray remains the primary modality of diagnosis for pleural disorders in the ICU. It can be nonspecific and may miss subtle findings. Ultrasound has become a useful tool to the bedside clinician to aid in diagnosis and management of pleural disease. The majority of pleural space disorders resolve as the patient’s illness improves. There remain a few pleural processes that need specific therapies. While uncomplicated parapneumonic effusions do not have their own treatments. Those that progress to become a complex infected pleural space can have its individual complexity in therapy. Chest tube drainage remains the cornerstone in therapy. The use of intrapleural fibrinolytics has decreased the need for surgical referral. A large hemothorax or pneumothorax in patients admitted to the ICU represent medical emergencies and require emergent action. In this review we focus on the management of commonly encountered complex pleural space disorders in critically ill patients such as complicated pleural space infections, hemothoraces and pneumothoraces.

Abstract
Pleural sepsis stems from an infection within the pleural space typically from an underlying bacterial pneumonia leading to development of a parapneumonic effusion. This effusion is traditionally divided into uncomplicated, complicated, and empyema. Poor clinical outcomes and increased mortality can be associated with the development of parapneumonic effusions, reinforcing the importance of early recognition and diagnosis. Management necessitates a multimodal therapeutic strategy consisting of antimicrobials, catheter/tube thoracostomy, and at times, video-assisted thoracoscopic surgery.

Abstract
OBJECTIVE To assess whether dexamethasone (DXM) decreases the time to recovery in patients with parapneumonic pleural effusion. STUDY DESIGN This was a multicenter, randomized, double blind, parallel-group, placebo-controlled clinical trial of 60 children, ranging in age from 1 month to 14 years, with community-acquired pneumonia (CAP) and pleural effusion. Patients received either intravenous DXM (0.25?mg/kg/dose) or placebo every 6 hours over a period of 48 hours, along with antibiotics. The primary endpoint was the time to recovery in hours, defined objectively. We also evaluated complications and adverse events. RESULTS Among the 60 randomized patients (mean age, 4.7 years; 58% female), 57 (95%) completed the study. Compared with placebo recipients, the patients receiving DXM had a shorter time to recovery, after adjustment by severity group and stratification by center (hazard ratio, 1.95; 95% CI, 1.10-3.45; P?=?.021). The median time to recovery for patients receiving DXM was 68 hours (2.8 days) shorter than patients receiving placebo (109 hours vs 177 hours; P?=?.037). In exploratory subgroup analysis, the median time to recovery for patients with simple effusion receiving DXM was 76 hours (3.1 days) shorter than for patients with simple effusion receiving placebo (P?=?.017). The median time to recovery for patients with complicated effusion receiving DXM was 14 hours (0.5 days) shorter than for patients with complicated effusion receiving placebo (P?=?.66). The difference in the effect of DXM in the 2 severity groups was not statistically significant (P?=?.138 for interaction). There were no significant differences in complications or adverse events attributable to the study drugs, except for hyperglycemia. CONCLUSION In this trial, DXM seemed to be a safe and effective adjunctive therapy for parapneumonic pleural effusion. TRIAL REGISTRATION ClinicalTrials.gov: NCT01261546.

Abstract
BACKGROUND The selection of ideal candidates for surgical intervention among patients with parapneumonic pleural effusion remains challenging. In this retrospective study, we sought to identify the main predictors of surgical treatment and devise a simple scoring system to guide surgical decision-making. METHOD Between 2005 and 2014, we identified 276 patients with parapneumonic pleural effusion. Patients in the training set (n=201) were divided into two groups according to their treatment modality (non-surgery vs. surgery). Using multivariable logistic regression analysis, we devised a scoring system to guide surgical decision-making. The score was subsequently validated in an independent set of 75 patients. RESULTS A white blood cell count >13,500/µL, pleuritic pain, loculations, and split pleura sign were identified as independent predictors of surgical treatment. A weighted score based on these factors was devised, as follows: white blood cell count >13,500/µL (one point), pleuritic pain (one point), loculations (two points), and split pleura sign (three points). A score >4 was associated with a surgical approach with a sensitivity of 93.4%, a specificity of 82.4%, and an area under curve (AUC) of 0.879 (95% confidence interval: 0.828-0.930). In the validation set, a sensitivity of 94.3% and a specificity of 79.6% were found (AUC=0.869). CONCLUSIONS The proposed scoring system reliably identifies patients with parapneumonic pleural effusion who are candidates for surgery. Pending independent external validation, our score may inform the appropriate use of surgical interventions in this clinical setting.

Abstract
BACKGROUND: Parapneumonic effusions complicating pneumonia are associated with increased morbidity and mortality. AIM: To determine the role of the clinical, laboratory and radiographic features to the differential diagnosis of patients with community- acquired pneumonia (CAP) without effusion, uncomplicated parapneumonic effusion (UCPPE) and complicated parapneumonic effusion (CPPE). MATERIAL AND METHODS: We analysed 148 patients with CAP without effusion, 50 with UCPPE and 44 with CPPE. In three groups of patients, the majority was male patients (58.11%, 58%, 61.36%) consequently. RESULTS: The chronic heart failure was the most common comorbidity in a group with CAP (28; 18.92%) and UCPPE (7; 14%), alcoholism (12;12.77%) in a group with CPPE. Patients with CPPE had significantly longer fever compared to patients with CAP without effusion (p = 0.003). Pleuritic chest pain (86.36%) and dyspnea (88.64%) were the most common symptoms in CPPE, then to group with UCPPE (60%; 52%), and in CAP without effusion (25.68%; 47,97%). Diffuse pulmonary changes were detected more frequently in the group with CAP without effusion compared with the group with CPPE (64.86 % vs. 27.27 %), while the segment lung changes were more common in patients with CPPE (50% vs. 20.27%). Patients with CPPE were significant with higher erythrocytes sedimentation rate (ESR), white blood cells (WBC) and serum C- reactive protein (CRP) than it the other two groups (p = 0.00090, p = 0.01, p= 0.000065). CONCLUSION: Proper analysis of clinical, laboratory and radiographic features of patients with CAP and parapneumonic effusion can prevent mismanagement in these patients and will reduce morbidity and mortality.

Abstract
BACKGROUND Parapneumonic empyema patients with coronary artery disease and reduced left ventricular ejection fraction are risky to receive surgical decortication under general anesthesia. Non-intubated video-assisted thoracoscopy surgery is successfully performed to avoid complications of general anesthesia. We performed single-port non-intubated video-assisted flexible thoracoscopy surgery in an endoscopic center. In this study, the possible role of our modified surgery to treat fibrinopurulent stage of parapneumonic empyema with high operative risks is investigated. METHODS We retrospectively reviewed fibrinopurulent stage of parapneumonic empyema patients between July 2011 and June 2014. Thirty-three patients with coronary artery disease and reduced left ventricular ejection fraction were included in this study. One group received tube thoracostomy, and the other group received single-port non-intubated video-assisted flexible thoracoscopy surgery decortication. Patient demographics, characteristics, laboratory findings, etiology, and treatment outcomes were compared. RESULTS Mean age of 33 patients (24 males, 9 females) was 76.2 ± 9.7 years. Twelve patients received single-port non-intubated video-assisted flexible thoracoscopy surgery decortication, and 21 patients received tube thoracostomy. Visual analog scale scores on postoperative first hour and first day were not significantly different in two groups (p value = 0.5505 and 0.2750, respectively). Chest tube drainage days, postoperative fever subsided days, postoperative hospital days, and total length of stay were significantly short in single-port non-intubated video-assisted flexible thoracoscopy surgery decortication (p value = 0.0027, 0.0001, 0.0009, and 0.0065, respectively). Morbidities were low, and mortality was significantly low (p value = 0.0319) in single-port non-intubated video-assisted flexible thoracoscopy surgery decortication. CONCLUSIONS Single-port non-intubated video-assisted flexible thoracoscopy surgery decortication may be suggested to be a method other than tube thoracostomy to deal with fibrinopurulent stage of parapneumonic empyema patients with coronary artery disease and reduced left ventricular ejection fraction.

Abstract
The aim of the study was to compare differences between lymphoma and inflammation as indicated by high diffuse uptake of F-fluorodeoxyglucose (F-FDG) in the spleen, liver, and bone marrow without increased F-FDG uptake in the lymph nodes and without enlarged peripheral lymph nodes.Eighteen lymphoma patients and 14 inflammation patients were examined with F-FDG positron emission tomography-computer tomography (PET-CT). All patients displayed high diffuse uptake of F-FDG in the spleen, liver, and bone marrow without increased F-FDG uptake in the lymph nodes and without enlarged peripheral lymph nodes. Our analyses compared the maximum standardized uptake values (SUVmax) of F-FDG uptake ratios between the spleen/liver, the spleen/bone marrow, and the liver/bone marrow and further compared spleen sizes between lymphoma and inflammation patients.Using Student t test, no significant differences were found in the SUVmax ratios of spleen/liver and liver/bone marrow between the lymphoma and inflammation patients (t = 0.853, P = 0.401 > 0.05; t = 1.622, P = 0.115 > 0.05). However, the SUVmax ratio of the spleen/bone marrow of the lymphoma patients was significantly different from that of the inflammation patients (t = 2.426, P = 0.021 < 0.05). The spleen size between the lymphoma and inflammation patients was also significantly different (t = 2.911, P = 0.007 < 0.05).As indicated by F-FDG PET-CT, our study demonstrated that lymphoma and inflammation patients displayed a few differences despite both having high diffuse uptake of F-FDG in the spleen, liver, and bone marrow without enlarged peripheral lymph nodes and without increased F-FDG uptake in lymph nodes.

Abstract
OBJECTIVE To review the current literature in reference to the pathophysiology, diagnosis, and treatment of pyothorax in dogs and cats. ETIOLOGY Pyothorax, also known as thoracic empyema, is characterized by the accumulation of septic purulent fluid within the pleural space. While the actual route of pleural infection often remains unknown, the oral cavity and upper respiratory tract appear to be the most common source of microorganisms causing pyothorax in dogs and cats. In human medicine, pyothorax is a common clinical entity associated with bacterial pneumonia and progressive parapneumonic effusion. DIAGNOSIS Thoracic imaging can be used to support a diagnosis of pleural effusion, but cytologic examination or bacterial culture of pleural fluid are necessary for a definitive diagnosis of pyothorax. THERAPY The approach to treatment for pyothorax varies greatly in both human and veterinary medicine and remains controversial. Treatment of pyothorax has classically been divided into medical or surgical therapy and may include administration of antimicrobials, intermittent or continuous thoracic drainage, thoracic lavage, intrapleural fibrinolytic therapy, video-assisted thoracic surgery, and traditional thoracostomy. Despite all of the available options, the optimal treatment to ensure successful short- and long-term outcome, including the avoidance of recurrence, remains unknown. PROGNOSIS The prognosis for canine and feline pyothorax is variable but can be good with appropriate treatment. A review of the current veterinary literature revealed an overall reported survival rate of 83% in dogs and 62% in cats. As the clinical presentation of pyothorax in small animals is often delayed and nonspecific, rapid diagnosis and treatment are required to ensure successful outcome.

Abstract
Parapneumonic pleural effusions represent the main cause of pleural infections. Their incidence is constantly increasing. Although by definition they are considered to be a "parapneumonic" phenomenon, the microbial epidemiology of these effusions differs from pneumonia with a higher prevalence of anaerobic bacteria. The first thoracentesis is the most important diagnostic stage because it allows for a distinction between complicated and non-complicated parapneumonic effusions. Only complicated parapneumonic effusions need to be drained. Therapeutic evacuation modalities include repeated therapeutic thoracentesis, chest tube drainage or thoracic surgery. The choice of the first-line evacuation treatment is still controversial and there are few prospective controlled studies. The effectiveness of fibrinolytic agents is not established except when they are combined with DNase. Antibiotics are mandatory; they should be initiated as quickly as possible and should be active against anaerobic bacteria except for in the context of pneumococcal infections. There are few data on the use of chest physiotherapy, which remains widely used. Mortality is still high and is influenced by underlying comorbidities.

Abstract
Rationale Optimal management of complicated parapneumonic effusions (CPPE) remains controversial. Objectives to assess safety and efficacy of iterative therapeutic thoracentesis (ITTC), the first-line treatment of CPPE in Rennes University Hospital. Methods Patients with CPPE were identified through our computerized database. We retrospectively studied all cases of CPPE initially managed with ITTC in our institution between 2001 and 2010. ITTC failure was defined by the need for additional treatment (i.e. surgery or percutaneous drainage), or death. Results Seventy-nine consecutive patients were included. The success rate was 81% (n = 64). Only 3 patients (4%) were referred to thoracic surgery. The one-year survival rate was 88%. On multivariate analysis, microorganisms observed in pleural fluid after Gram staining and first thoracentesis volume ≥450 mL were associated with ITTC failure with adjusted odds-ratios of 7.65 [95% CI, 1.44–40.67] and 6.97 [95% CI, 1.86–26.07], respectively. The main complications of ITTC were iatrogenic pneumothorax (n = 5, 6%) and vasovagal reactions (n = 3, 4%). None of the pneumothoraces required chest tube drainage, and no hemothorax or re-expansion pulmonary edema was observed. Conclusions Although not indicated in international recommendations, ITTC is safe and effective as first-line treatment of CPPE, with limited invasiveness.

Abstract
Background Intrapleural fibrinolytics have been used successfully worldwide for the management of complicated pleural effusions and empyema. Bleeding complications are usually mentioned as rare side effects, but there is no clear information in the literature addressing the alarming outcome that might result following the use of alteplase as a fibrinolytic in the management of complicated parapneumonic effusions. We present a rare, if not unique, case of intrapleural hemorrhage requiring transfusion after alteplase use as a fibrinolytic in a 6-year-old male with complicated parapneumonic effusion. Methods A search of the PubMed database was carried out, using a combination of the following terms: alteplase, fibrinolytic, intrapleural hemorrhage, and side effects. Results The majority of studies found in the search concentrated on the efficacy of intrapleural fibrinolytics in the management of pleural effusion, but very few of the reports addressed the bleeding complications which may be caused by the treatment. Conclusion Although intrapleural and systemic hemorrhage are rare side effects of intrapleural fibrinolytic use, the health care provider must be watchful for these potentially life-threatening complications. Further studies are needed to understand not only the efficacy of fibrinolytics but also their safety, especially in children.

Abstract
PURPOSE OF REVIEW Spontaneous bacterial empyema (SBEM) is defined as spontaneous infection of a preexisting hepatic hydrothorax. SBEM is diagnosed after exclusion of pneumonia, and, in patients with liver cirrhosis, it is still associated with significant morbidity and mortality. To date, studies focusing on SBEM are rare. This review will highlight the recent data focusing on the clinical characteristics, bacteriology, management, and outcome predictors of cirrhotic patients with SBEM. RECENT FINDINGS The Enterobacteriaceae (Escherichia coli and Klebsiella pneumoniae) are the major causative pathogens isolated from SBEM patients. Therefore, the cornerstone of therapy is antibiotic therapy with immediate empirical use of third-generation cephalosporins as first-line treatment. Chest-tube placement is not necessary. Regression analysis identified three independent factors related to poor outcome: high score of the model for end-stage liver disease-sodium (MELD-Na), initial ICU admission, and initial antibiotic treatment failure. High MELD-Na score may be a useful predictor of SBEM mortality in cirrhotic patients. SUMMARY Although SBEM is a rare complication of cirrhosis, the high mortality rate should increase physicians' index of suspicion in cirrhotic patients with hydrothorax and prompt immediate diagnostic thoracentesis. The MELD-Na score rather than Child-Pugh score may be a strong predictor of in-hospital mortality of SBEM patients.

Abstract
Pleural effusions can present in 40% of patients with pneumonia. Presence of an effusion can complicate the diagnosis as well as the management of infection in lungs and pleural space. There has been an increase in the morbidity and mortality associated with parapneumonic effusions and empyema. This calls for employment of advanced treatment modalities and development of a standardized protocol to manage pleural sepsis early. There has been an increased understanding about the indications and appropriate usage of procedural options at clinicians' disposal.

Abstract
AIM A double blind randomized cross over trial to compare the rate of decortication, safety and efficacy of intrapleural instillation of Alteplase vs. Placebo in empyema and complicated parapneumonic effusions (CPE). METHODS Patients diagnosed with empyema or CPE and considered for surgery were given the option to enter into this trial. Intrapleural instillation of the 'Drug' was given daily for three days. Patient that failed the first arm of the trial were offered surgery or to cross over to the second arm. Failure was documented if pleural effusions did not improve by 50% on CT scans after three doses of the 'Drug' or if these effusions recurred within six weeks. RESULTS One hundred and eight patients were evaluated and one hundred enrolled in the trial. 32 patients were excluded, 29 for noninfectious loculated effusions, two for protocol violation and one for bleeding at chest tube site. There were 17 patients with empyema and 51 patients with CPE. 58 of the 61 patients (26 crossed over) with empyema/CPE resolved with Alteplase therapy compared to 4 of the 32 patients (one crossed over) treated with Placebo (p value <0.001). None of the patients went to surgery. Adverse events with Alteplase therapy compared to Placebo were not statistically significant, with chest pain and bleeding complications being the most common. CONCLUSION Intrapleural instillation of Alteplase is significantly more effective than Placebo in patients with empyema and PPE (95% vs.12%). This study demonstrates it is safe and efficacious with minimal adverse reactions.

Abstract
Empyema thoracis causes high mortality, and its incidence is increasing in both children and adults. Parapneumonic effusions (PPEs) develop in about one-half of patients hospitalized with pneumonia, and their presence increases mortality by about four-fold. PPEs can be divided into simple PPEs, complicated PPEs, and frank empyema. Two guideline statements on the management of PPEs in adults have been published by the British Thoracic Society (BTS) and the American College of Chest Physicians; a third guideline statement published by the BTS focused on management of PPEs in children. The two adult guideline statements recommend drainage of the pleural space in complicated PPEs and frank empyema. They also recommend the use of intrapleural fibrinolysis in those who do not show improvement. The pediatric guideline statement recommends adding intrapleural fibrinolysis to those treated by tube thoracostomy if they have loculated pleural space or thick pus. Published guideline statements on the management of complicated PPEs and empyema in adults and children recommend the use of intrapleural fibrinolysis in those who do not show improvement after pleural space drainage. However, published clinical trial reports on the use of intrapleural fibrinolysis for the treatment of pleural space sepsis suffer from major design and methodologic limitations. Nevertheless, published reports have shown that the use of intrapleural fibrinolysis does not reduce mortality in adults with parapneumonic effusions and empyema. However, intrapleural fibrinolysis enhances drainage of infected pleural fluid and may be used in patients with large collections of infected pleural fluid causing breathlessness or respiratory failure, but a proportion of these patients will ultimately need surgery for definite cure. Intrapleural streptokinase and urokinase seem to be equally efficacious in enhancing infected pleural fluid drainage in adults. In most of the published studies in adults, the use of intrapleural fibrinolysis was not associated with serious side effects. There is emerging evidence that the combination of intrapleural tissue plasminogen activator (tPA) and deoxyribonuclease (DNase) is significantly superior to tPA or DNase alone or placebo in improving pleural fluid drainage in patients with pleural space infection. In children, intrapleural fibrinolysis has not been shown to reduce mortality, but has been shown to enhance drainage of the pleural space and was safe. In addition, two prospective, randomized trials have shown that intrapleural fibrinolysis is as effective as video-assisted thoracoscopic surgery for the treatment of childhood empyema and is a more cost-effective treatment and therefore should be the primary treatment of choice.

Abstract
Klebsiella pneumoniae is the major cause of community-acquired pyogenic infections in Taiwan and is becoming an increasing problem in acute thoracic empyema. This study evaluated the clinical and microbiological characteristics of community-acquired thoracic empyema or complicated parapneumonic effusion caused by K. pneumoniae in Taiwanese adults treated during the period 2001-2008 at a tertiary medical center. All clinical isolates were examined for capsular serotypes K1/K2, and pulsed-field gel electrophoresis (PFGE) was performed on strains of the same serotype. K. pneumoniae was the most frequent cause of community-acquired thoracic empyema or complicated parapneumonic effusion. It was associated with high mortality (32.4%) and was an independent risk factor for fatal outcome. Diabetes mellitus, liver cirrhosis, and bronchogenic carcinoma were independent risk factors for K. pneumoniae infection. Serotypes K1 (9/37, 24.3%) and K2 (13/37, 35.1%) were the prevalent strains but did not predispose patients to poor outcome compared with other non-K1/K2 serotypes. There was no major cluster of isolates found among serotype K1/K2 strains. In summary, physicians should be aware of the risk factors for thoracic empyema or complicated parapneumonic effusion caused by K. pneumoniae and the associated high mortality, and monitor these patients more closely.

Abstract
Pleural effusion is defined as an accumulation of fluid in the pleural space in excess of 15 to 20 mls. The aetiology for the development of a pleural effusion includes changes in hydrostatic or colloid-osmotic pressure of pleural and pulmonary capillaries, changes in pleural vascular permeability and impaired lymphatic drainage. About 5% to 12% of patients referred for emergency medical treatment are diagnosed with a pleural effusion, making it a common finding on hospital admission. The excess of pleural fluid may be triggered by pleuro-pulmonary infection, malignancy, or conditions of cardiac, renal or hepatic origin. Subsequent management is guided mainly by aetiology and to a lesser degree by symptoms. This paper provides a review of pathophysiology, diagnosis and management of the condition and addresses specific issues regarding the perioperative care of these patients.

Abstract
Until recently, pyothorax in the cat has been generally considered to have a poor prognosis. However, it has become clear that most cats that survive the first 48 h following presentation can be successfully treated with aggressive medical management. In this second part of a two-part review, logical guidelines for the management of the disease are discussed, with particular emphasis on antimicrobial selection. Patient stabilisation and supportive care, techniques for pleural space drainage and lavage and indications for surgery are reviewed.

Abstract
Pleural empyema remains a frequently encountered clinical problem and is responsible for significant morbidity and mortality worldwide. Its diagnosis may be difficult; delays in diagnosis and treatment may contribute to morbidity, complications, and mortality. The management of parapneumonic effusion and empyema depends on timely, stage-dependent therapy and the underlying etiology. Thoracentesis and antibiotics remain the cornerstones of treatment in stage I disease. In the early fibrinopurulent phase (stage II) thoracoscopic methods should be considered. As treatment strategy for this stage, fibrinopurulent pleural empyema entails thorough debridement of multiloculated collections from the pleural cavity by video-assisted thoracic surgery. After evacuation of multilocular effusions and the removal of fibrin deposits with drainage by two intercostal chest tubes, irrigation treatment helps to achieve clarity of the pleural discharge. Open thoracotomy and decortication are reserved for organized, multiloculated empyema with lung entrapment (stage III disease). Early drain removal may lead to rapid symptomatic recovery and complete resolution.

Abstract
The infectious effusion, one of the most frequent causes of pleural effusions in the clinical practice, is a sign of complication of the pneumonic disease. The early recognition of the parapneumonic effusion is crucial to determine the best treatment form and reduce the risk of morbidity and mortality. The evolution in the diagnostic methods and the contribution of several studies published in the literature allowed to establish evidence-based guidelines that are used to guide the treatment of the parapneumonic pleural effusion and empyema.

Clinical characteristics and outcomes of empyema thoracis in 117 patients: a comparative analysis of tuberculous vs. non-tuberculous aetiologies. Respir Med 2006; 101:423-30. [PMID: 17045789 DOI: 10.1016/j.rmed.2006.07.016] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2005] [Revised: 06/27/2006] [Accepted: 07/25/2006] [Indexed: 11/24/2022]
Abstract
BACKGROUND Empyema thoracis remains a major problem in developing countries. Clinical outcomes in tuberculous empyema are generally believed to be worse than in non-tuberculous aetiologies because of the presence of concomitant fibrocavitary parenchymal disease, frequent bronchopleural fistulae and poor general condition of patients. We performed a prospective study over a 2-year period with the objective of comparing the clinical characteristics and outcomes of patients with tuberculous vs. non-tuberculous empyema. METHODS Prospective study of all cases of non-surgical thoracic empyema seen at a tertiary care centre in North India over a 2-year period. A comparative analysis of clinical characteristics, treatment modalities and outcomes of patients with tuberculous vs. non-tuberculous empyema was carried out. Factors associated with poor outcomes were analysed using multivariate logistic regression. RESULTS One hundred and seventeen cases of empyema were seen in the study period of which 95 had non-tuberculous and 41 had tuberculous empyema. Malnutrition and bronchopleural fistulae (BPF) were more common and duration of symptoms longer in the tuberculous empyema group. Time to resolution of fever, duration of pleural drainage and pleural thickening >2 cm were significantly greater as well. Eight (10.5%) patients with non-tuberculous empyema and four (9.8%) with tuberculous empyema succumbed. Presence of a BPF was significantly associated with poor outcomes on multivariate logistic regression analysis. CONCLUSIONS Tuberculous empyema remains a common cause of thoracic empyema in India though it ranked second amongst all causes of empyema after community acquired lung infections in this study. Tuberculous empyema is associated with longer duration of symptoms, greater duration of pleural drainage and more residual pleural fibrosis.

Abstract
To evaluate the effective dose frequency (once daily vs. twice daily) of intrapleural urokinase treatment in children who required tube thoracostomy for drainage of a complicated parapneumonic effusion, we designed a randomised prospective study in a tertiary medical centre in Taiwan. From June 2002 to January 2005, 30 paediatric patients with complicated parapneumonic effusion who had received chest tube drainage were randomised 1 : 1 to the once-daily (urokinase 5000-6000 IU/kg/dose) or twice-daily (urokinase 2500-3000 IU/kg/dose) treatment. We compared clinical manifestations and outcomes in both groups. There were no differences in pleural effusion characteristics between the groups. Six patients had Streptococcus pneumoniae, one had Staphylococcus aureus, one had Group A Streptococcus, and 22 had unknown pathogens. There were no significant differences between the once- vs. twice-daily group in the amount of drained pleural fluid (564.9 +/- 422.1 ml vs. 560.5 +/- 198.6 ml, respectively), fever duration after chest tube insertion (4.3 +/- 3.2 days vs. 5.3 +/- 2.7 days), or total admission days (14.3 +/- 3.9 days vs. 14.6 +/- 3.0 days) (p > 0.05 for all). Only two patients (one in each group) required the surgery. Thus, we found that both once- and twice-daily administration of urokinase were similarly efficacious, and resulted in good clinical outcomes. Both obviated the need for surgery in most (93%) cases of pneumonia with complicated parapneumonic effusion in this series. A larger, multicentre study is necessary to verify our findings.
