Management of pleural effusion and empyema in a third-level pediatric surgical center.

Pleural effusion and empyema are frequent complications of acute bacterial pneumonia in children. To date, evidence regarding the optimal treatment of this condition is limited in the literature. Patients with pleural effusion and empyema admitted at our Department of Pediatric Surgery over the last ten years were enrolled in this retrospective study, and successively compared with the clinical charts of patients treated before the introduction of a new diagnostic and therapeutic algorithm. In particular, primary outcomes investigated between pre- and postalgorithm period were the use of diagnostic tools and antibiotics, the need for additional therapeutic approaches, complications, and the length of stay. After the introduction of the new algorithm there were a decrease in the use of chest radiography for re-evaluation (100% vs. 79%, P=0.003), a more focused use of computed tomography (68% vs. 15%, P=0.001), and a decrease in the use of a second computed tomography (18% vs. 3%, P=0.07); in favor of an increase in the use of the ultrasound scan (40% vs. 100%, P=0.001). There was also a shift from the use of chest tube drainage alone to the use of drainage for urokinase administration (50% vs. 92.3%, P=0.001), and a statistically significant decrease in the need for video-assisted thoracoscopic surgery (25% vs. 7.7%, P=0.001). The introduction of a diagnostic and therapeutic algorithm for the management of pediatric pleural effusion and empyema has notably resulted in a decrease in the utilization of radiography and computed tomography and an increase in the use of ultrasonography, reducing unnecessary radiation exposure in children and overall costs.

The diagnostic value of interleukin-36 cytokines in pleural effusions of varying etiologies

BackgroundThe clinical management of pleural effusion (PE) poses challenges due to its diverse etiologies. The objective of this research was to investigate the concentrations of interleukin-36 (IL-36) cytokines in pleural fluid (PF) from different etiologies and assess their diagnostic efficacy in distinguishing the causes of PE. MethodsThis study enrolled 89 patients with confirmed PE, comprising 11 cases classified as transudate, 24 cases as malignant pleural effusion (MPE), 24 cases as tuberculous pleural effusion (TPE), and 30 cases as parapneumonic pleural effusion (PPE). The PPE group was further subdivided into 20 cases of uncomplicated parapneumonic effusion (UPPE) and 10 cases of complicated parapneumonic effusion (CPPE)/empyema. The concentrations of IL-36 cytokines in the PF of all 89 patients were quantified by the enzyme-linked immunosorbent assay (ELISA). ResultsIL-36α exhibited excellent diagnostic accuracy in TPE, achieving a sensitivity of 91.7 % and specificity of 83.1 %, along with a cut-off value of 435.3 pg/ml. IL-36Ra also demonstrated relatively favorable diagnostic performance in PPE, with a sensitivity of 80.0 % and specificity of 76.3 %, along with a cut-off value of 390.8 pg/ml. Multivariable logistic regression models were successfully developed for both TPE and PPE, confirming their diagnostic utility. Furthermore, the levels of IL-36Ra were notably elevated in CPPE/empyema in comparison to UPPE. Moreover, in PF, IL-36γ exhibited positive associations with both IL-36α and IL-36Ra. ConclusionIL-36α and IL-36Ra may serve as novel biomarkers for diagnosing TPE and PPE, respectively. The multivariate models established significantly enhance the diagnostic efficacy of both TPE and PPE. Furthermore, IL-36Ra can function as an indicator for assessing the extent of pleural inflammation. Additionally, the interaction among IL-36 cytokines in PF may contribute to their expression modulation.

Expert Review on Contemporary Management of Common Benign Pleural Effusions.

Heart failure (HF) and cirrhosis are frequently associated with pleural effusions (PEs). Despite their apparently benign nature, both HF-related effusions and hepatic hydrothorax (HH) have poor prognosis because they represent an advanced stage of the disease. Optimization of medical therapy in these two entities involve not only the use of diuretics, but also other pharmacological therapies. For instance, all HF patients with reduced or mildly reduced left ventricular ejection fraction can benefit from angiotensin receptor-neprilysin inhibitors, beta blockers, mineralocorticoid receptor antagonists, and sodium-glucose cotransporter 2 inhibitors. Conversely, it is better for HH patients to avoid nonselective beta blockers. Refractory cardiac- and cirrhosis-related PEs are commonly managed by iterative therapeutic thoracentesis. When repeated aspirations are needed, thereby diminishing quality of life, the insertion of an indwelling pleural catheter (IPC) may be warranted. However, in selected HH patients who are diuretic-resistant or diuretic-intractable, placement of transjugular intrahepatic portosystemic shunts should be considered as a bridge to liver transplantation, whereas in transplant candidates the role of IPC is debatable. Another benign condition, pleural tuberculosis (TB) is a serious health problem in developing countries. Diagnostic certainty is still a concern due to the paucibacillary nature of the infection, although the use of more sensitive nucleic acid amplification tests is becoming more widespread. Its treatment is the same as that of pulmonary TB, but the potential drug interactions between antiretroviral and anti-TB drugs in HIV-coinfected patients as well as the current recommended guidelines for the different types of anti-TB drugs resistance should be followed.

Predictors of prolonged pleural effusion after Fontan operation.

Prolonged pleural effusion is a fairly common condition which has considerable impact on complicated and longer hospital stays after Fontan surgery. Identifying the patient population prone to have pleural effusions is still seeking for an answer. This study is to determine the variables that may predict prolonged pleural effusion according to the data of 69 patients who underwent Fontan operation between June 2018 and December 2020 and survived to date. Prolonged pleural effusion was defined as the need for a chest tube for more than 7 days. Two patient groups, with and without prolonged effusion, were compared in terms of pre-, peri-, and post-operative variables. The patients were subdivided into "high-risk" and "low-risk" groups based on the pre-operative catheterisation data. The most frequent main diagnosis was tricuspid atresia (n: 13, 19%). Among 69 patients, 28 (40%) had prolonged pleural effusion whereas 11 (16%) had effusions that lasted longer than 14 days. Ten patients among prolonged effusion group (35%) had pulmonary atresia coexistent with the main diagnosis. Fontan operation was performed in 6 patients (8.7%) over the age of 10, and 4 of these patients (67%) had prolonged pleural effusion. Among numerous variables, statistical significance between the two groups was achieved in pre-operative mean pulmonary artery pressure, post-operative albumin, C-reactive protein levels, length of hospital stay, duration of chest tube drainage, and amount of effusion per day. Early recognition and treatment strategies with routine medical protocol use remain to be the cornerstone for the management of post-operative prolonged pleural effusions after Fontan surgery.

Pleural effusion in critically ill patients and intensive care setting.

Pleural effusion usually causes a diagnostic dilemma with a long list of differential diagnoses. Many studies found a high prevalence of pleural effusions in critically ill and mechanically ventilated patients, with a wide range of variable prevalence rates of up to 50%-60% in some studies. This review emphasizes the importance of pleural effusion diagnosis and management in patients admitted to the intensive care unit (ICU). The original disease that caused pleural effusion can be the exact cause of ICU admission. There is an impairment in the pleural fluid turnover and cycling in critically ill and mechanically ventilated patients. There are also many difficulties in diagnosing pleural effusion in the ICU, including clinical, radiological, and even laboratory difficulties. These difficulties are due to unusual presentation, inability to undergo some diagnostic procedures, and heterogenous results of some of the performed tests. Pleural effusion can affect the patient's outcome and prognosis due to the hemodynamics and lung mechanics changes in these patients, who usually have frequent comorbidities. Similarly, pleural effusion drainage can modify the ICU-admitted patient's outcome. Finally, pleural effusion analysis can change the original diagnosis in some cases and redirect the management toward a different way.

Operative versus percutaneous drainage with fibrinolysis for complicated pediatric pleural effusions: A nationwide analysis

Management of complicated pleural effusions and empyema using tube thoracostomy with intrapleural fibrinolysis versus surgical drainage has been debated for decades. However, there remains considerable variation in management with these approaches in the pediatric population. This study aims to compare the nationwide outcomes of pediatric patients with complicated pleural effusions. Patients <18 years old with a diagnosis of pleural effusion or empyema associated with pneumonia were identified from the Nationwide Readmissions Database (2016-2018). Demographics, hospital characteristics, and complications were compared among patients undergoing isolated percutaneous drainage (PD), percutaneous drainage with intrapleural fibrinolysis (PDF), or operative drainage (OD) using standard statistical tests. 5424 patients (age 4 [IQR 1-11] years) were identified with a pleural effusion or empyema who underwent percutaneous or surgical intervention. PD (22%) and OD (24%) were utilized more frequently than PDF (3%). Index complications, including bleeding and postprocedural air leak, were similar between groups. Those receiving PDF had lower index length of stay (LOS) and admission costs. Thirty-day and overall readmission rates were highest in patients receiving PD (15% and 24%) and OD (12% and 23%) versus PDF, all p<0.001. Those receiving OD had fewer readmission complications including recurrent effusion or empyema, pneumonia, and bleeding. Overall readmission cost was highest in those receiving PD (p=0.005). In this nationwide cohort, PDF was associated with lower index admission cost, shorter LOS and lower rates of readmissions compared to OD. This knowledge should be used to improve selection of these treatments in this patient population. Retrospective Comparative LEVEL OF EVIDENCE: III.

The thoracoscopic approach in the management of parapneumonic pleural effusion in children

Background: Parapneumonic pleural effusion is a relatively common entity and continues to be a major cause of morbidity in children. However, managing this disease is still a matter of controversy between surgical and non-surgical options. With the advancement of mini-invasive surgery, video-assisted thoracoscopic surgery (VATS) has become a mainstay in the treatment of parapneumonic effusion in children. This study aimed to evaluate the clinical characteristics and pathological features of parapneumonic pleural effusion in children and to explore the feasibility and safety of the thoracoscopic approach in the pediatric population. Methods: The clinical data of all patients who underwent VATS for parapneumonic effusion between 2007 and 2021 were analyzed retrospectively. Factors that were documented included demographic criteria, clinical manifestations, preoperative examinations, therapeutic procedures, intraoperative findings, postoperative complications, and outcomes. Results: Totally, 35 patients with a mean age of 5.14 ± 3.9 years were operated on thoracoscopically. The mean duration of evolution before VATS was 9 days ± 4. All children were hospitalized in a Pediatric Continuing Care Unit. Antibiotic therapy was administrated in combination in all cases. Corticosteroid therapy was used in 2 patients. Thoracentesis was performed in 6 patients. Thoracostomy tube drainage was placed before surgery in 11 patients. The average duration of drainage before VATS was 6 days ± 4. VATS decortication and/or debridement was indicated as second-line in 23 patients. The average duration of the surgery was 51 minutes (20 min - 115 min). There is no conversion to open surgery and no intraoperative procedure-dependent complication. 4 children have early complications after the VATS and one patient had a late postoperative complication. There were no deaths during the hospital stay or follow-up. Conclusion: In skilled hands, VATS is safe, feasible, and effective in the management of parapneumonic pleural effusion in children with excellent outcomes.

Tissue plasminogen activator with prolonged dwell time effectively evacuates pleural effusions

ObjectivesFibrinolytic therapy can be effective for management of complex pleural effusions. Tissue plasminogen activator (tPA, 10 mg) and deoxyribonuclease (DNAse) every 12 h with a dwell time of one hour is a common strategy based on published data. We used a simpler protocol of tPA (4 mg) without DNAse but with a longer dwell time of 12 h, repeated daily. We reviewed our results.MethodsCharts were reviewed and demographics, clinical data and treatment information were abstracted. Outcomes were assessed based on radiographic findings and need for surgery.ResultsTwo hundred and fifteen effusions in 207 patients (8 bilateral) were identified. 85% were either infectious or malignant. Two hundred and forty nine chest tubes were used: 84% were 10 Fr or 12 Fr and 7% were PleurX®. Five hundred and thirty one doses of tPA were given. The median number of doses per effusion was 2 (range 1–10), and 84% of effusions were treated with three or fewer doses. There were no significant bleeding complications. Median time to chest tube removal was 6 days (range 1 to 98, IQR 4 to 10). Drainage was considered complete for 78% of effusions, while 6% required decortication.ConclusionsLow dose tPA daily with a 12 h dwell time may be as effective as the standard regimen of tPA and DNAse twice daily with one hour dwell. For most patients only three doses were required, and small pigtail catheters were sufficient. This regimen uses less medication and is logistically much easier than the current standard.

Diagnostic role of video-assisted thoracoscopy in the management of indeterminate pleural effusion.

The management of pleural effusion usually involves the drainage of the effusion, identification, and treatment of the underlying cause (s). Studies have shown that the initial diagnostic techniques do not give conclusive diagnosis in some cases of pleural effusion. This group of patients described as patients with indeterminate or undiagnosed pleural effusion constitutes a significant proportion of patients with pleural effusion in clinical practice. In this study, we examined the role of video-assisted thoracoscopy (VAT) in the diagnostic work-up of these patients. To determine the diagnostic outcome of VAT in the management of indeterminate pleural effusion in our center. Consecutive patients who presented with pleural effusions and who met the inclusion criteria had video-assisted thoracoscopy for diagnostic purposes. Outcome measures including the diagnostic yield, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of VAT in patients with indeterminate pleural effusion, duration of the procedure, duration of hospitalization after the procedure, and complications for all the patients were documented and analyzed. Of the 22 patients with indeterminate pleural effusion, conclusive diagnosis was obtained in 18 (81.8%) with a sensitivity of 91.7% [95% confidence interval (CI); 61.5-99.8%], specificity of 100% (95% CI; 69.1-100%), PPV of 100% (95% CI; 0-100%), and NPV of 90.9% (95% CI; 60.5-98.5%) for malignancy and a sensitivity of 78% (95% CI; 40-97%), a specificity of 100% (95% CI; 75.3-100%), PPV of 100% (95% CI; 0-100%), and NPV of 86.7% (95% CI; 65.7-95.7%) for tuberculosis. Our results show that video-assisted thoracoscopy plays a useful role in our center in obtaining diagnosis in patients with indeterminate pleural effusion.

Intrapleural Instillation of Sodium Bicarbonate versus Urokinase in Management of Complicated Pleural Effusion: A Comparative Cohort Study.

The main target is evacuation; however, with evidence about the value of intrapleural instillation of different fibrinolytic agents still under evaluation, our aim was comparing the effectiveness and safety of intrapleural instillation of sodium bicarbonate (NaHCO3) in comparison with urokinase in patients with infected pleural effusion. Our prospective cohort study included 40 patients with complicated empyema; the diagnosis was based on analysis of aspirated fluid in association with radiological and bacteriological culture. The patients were subjected to instillation of two different fibrinolytic agents; the first one was NaHCO3, the second was urokinase. The commonest underlying chest infection that was visualized by CT was pneumonia 70%. Nearly half of cases had community-acquired infection (45%), and more than half of them (55%) had anaerobic infection, and only five cases had TB pleural effusion based on ADA-positive, tuberculin skin test in addition to Abram's needles closed biopsy. The rate of repeated therapeutic thoracentesis success in each group was 85%; 80% in NaHCO3 group, and 90% in urokinase group, both of them was significantly equal, P=0.37. Moreover, the frequency of complications in all patients was less than 13%, hence hemothorax and iatrogenic pneumothorax was 12.5%, and only 10% of cases were admitted in ICU after the maneuver, with insignificant difference in between the groups. However, looking at the smaller rate of RTT failure of NaHCO3 or urokinase, the logistic regression model showed that RTT-NaHCO3 was insignificantly related to failure in both unadjusted and adjusted models, P=0.37 and 0.32, respectively, and only smoking habits increase the likelihood of failure 9-fold (OR=8.9, P=0.04) with respect to age, sex, and treatment methods. The efficacy of repeated therapeutic thoracentesis (RTT) with intrapleural instillation of NaHCO3 was effective and safe, the same as urokinase, with consideration that NaHCO3 was much more available and affordable than urokinase.

Local Anaesthetic Thoracoscopy for Pleural Effusion-A Narrative Review.

The incidence of pleural disease is increasing, and interventions are crucial in this subspecialist area of respiratory medicine. One of the cornerstones of pleural effusion investigation and management is medical, which is also known as local anaesthetic thoracoscopy. This allows fluid drainage, biopsy for diagnosis and preventative measures for further fluid potential build-up. This article summarises the evidence around this procedure through a narrative review of the available evidence.

Automated and manual microscopic analyses for leukocyte differential counts in exudative pleural effusions: Real-world disagreement and clinical application.

Differential leukocyte counts of pleural fluid are routinely recommended for the early diagnosis and management of exudative pleural effusions. Rapid automated cellular analysis agrees strongly with standard manual microscopic counts and has become a reality in many clinical laboratories. However, discordant results sometimes observed between automated and manual analyses raise concern about using automated analysis to aid prompt differential diagnosis. This study aimed to evaluate the real-world disagreement between automated and manual leukocyte analyses in exudative pleural effusions and to investigate whether the discordant results occur in specific cellular ranges or randomly. We conducted a retrospective study of patients who were diagnosed with parapneumonic pleural effusions (PPE), tuberculous pleural effusions (TPE), and malignant pleural effusions (MPE) between September 2018 and December 2020. Differential and predominant leukocyte counts were performed using an automated XN-350 analyzer with a two-part differential count consisting of polymorphonuclear (PMN) and mononuclear (MN) leukocytes and a manual method with Wright-stained cytospin slides. We compared the two methods on cases of 109 PPEs, 50 TPEs, and 116 MPEs. Although the overall correlation between the two methods for differential leukocyte counts was excellent, there were etiologic variations; MPEs showed a lower correlation compared to PPEs and TPEs. Automated-PMN predominance almost corresponded to manual cytospin-neutrophilic predominance. In contrast, ~10% of the automated-MN predominance did not correspond with the cytospin-lymphocytic predominance. These discrepancies occurred most in the automated-MN% range of 51% to 60%, followed by 61% to 70%. The PMN% range ≥50% and <30% on the automated analysis reliably corresponds to the neutrophilic and lymphocytic predominance, respectively. However, the MN% range of 51% to 70% may not coincide with lymphocytic predominance on manual cytospin analysis. This range leaves the potential cause of exudative pleural effusions open.
