Use of lung ultrasound (LUS) in resource-rich ICUs is still under investigation. The present study compares the utility of LUS to that of CXR in identifying pulmonary edema and pleural effusion in ICU patients. In addition, consolidation and pneumothorax were analyzed as secondary outcome measures. Material and Methods This is a prospective, single centric, observational study. Patients admitted in ICU were examined for lung pathologies, using LUS by a trained intensivist;and CXR done within 4 hours of each other. The final diagnosis was ascertained by an independent senior radiologist, based on the complete medical chart including clinical findings and the results of thoracic CT, if available. The results were compared and analyzed. Results Sensitivity, specificity and diagnostic accuracy of LUS was 95%, 94.4%, 94.67% for pleural effusion;and 98.33%, 97.78%, 98.00% for pulmonary edema respectively. Corresponding values with CXR were 48.33%, 76.67%, 65.33% for pleural effusion;and 36.67%, 82.22% and 64.00% for pulmonary edema respectively. Sensitivity, specificity and diagnostic accuracy of LUS was 91.30%, 96.85%, 96.00% for consolidation;and 100.00%, 79.02%, 80.00% for pneumothorax respectively. Corresponding values with CXR were 60.87%, 81.10%, 78.00% for consolidation;and 71.3%, 97.20%, 96.00% for pneumothorax respectively. Conclusion LUS has better diagnostic accuracy in diagnosis of pleural effusion and pulmonary edema when compared with CXR and is thus recommended as an effective alternative for diagnosis of these conditions in acute care settings. Our study recommends that a thoracic CT scan can be avoided in most of such cases.展开更多

Infusion chemotherapy is currently one of the most common intracavitary treatments for MPE. Unfortunately, there is no definitive consensus on which intracavitary infusion drug has the best effect on the treatment. The use of de-platinum-based thoracic perfusion therapy can offer several advantages, such as reducing drug toxicity and contributing to an improvement in patients’ physical condition. Therefore, this study was to investigate the clinical efficacy and safety of de-platinum-based pleural perfusion bevacizumab combined with Brucea Javanica Oil Emulsion Injection (BJOEI) in the treatment of malignant pleural effusion in advanced lung adenocarcinoma. Methods: A total of 60 patients diagnosed with lung adenocarcinoma and malignant pleural effusion were selected from Binzhou People’s Hospital, Shandong Provincial Cancer Hospital, and Binzhou Central Hospital between June 2022 and May 2024, with 30 cases treated in each group. The study was divided into two groups: the treatment group received bevacizumab injection perfusion in combination with intravenous infusion of Brucea Javanica Oil Emulsion Injection (BJOEI), while the control group received bevacizumab injection combined with cisplatin perfusion. To analyze the data and evaluate their efficacy and adverse reactions, such as disease control rate (DCR), overall response rate (ORR), Karnofsky Performance Status (KPS), vascular endothelial growth factor (VEGF), and so forth. Results: Following the treatment, the quality of life scores in both groups exhibited an increase compared to pre-treatment levels. Moreover, the enhancement observed in the treatment group was deemed statistically significant (P = 0.007). Following treatment, The expression of VEGF in the pleural effusion of both groups of patients was significantly decreased, and the disparity within the same group was found to be statistically significant (P P χ2 = 0.317, P = 0.573;χ2 = 0.218, P = 0.640). A stratified analysis of factors influencing the ORR revealed that the ORR in both groups exhibited statistical significance when the previous KPS score was below 70 (χ2 = 5.850, P = 0.016). The main adverse reactions in both groups included nausea, vomiting, gastrointestinal reactions, fatigue, and hematological toxicity. Among them, there was a statistically significant difference in the occurrence of gastrointestinal reactions and fatigue between the two groups (χ2 = 8.148, P = 0.004;χ2 = 6.696, P = 0.010). Conclusion: Bevacizumab, when combined with Brucea Javanica Oil Emulsion Injection (BJOEI), demonstrates noteworthy efficacy in treating malignant pleural effusion. This combination therapy reduces VEGF expression, in which the reduction supports the efficacy of thoracic perfusion and is associated with minimal adverse reactions, contributing to an improvement in patients’ physical condition and overall clinical tolerability, especially for the poor physique, especially in the elderly and KPS score is less than 70. Therefore, it can be considered a recommended approach for managing malignant pleural effusion, offering significant clinical value.展开更多

The sensitivity, specificity, accuracy and area under the curve （AUCR^ROC） of CEA and VEGF, VEGF/IFN-γ ratio, ADA and IFN-γ were measured by receiver operating characteristic curve （ROC）, The results showed that CEA, VEGF levels and VEGF/IFN-γ ratio were significantly higher and the ADA and IFN-γ levels were significantly lower in malignant group than those in tuberculous group （P〈0,01）, The sensitivity, specificity, accuracy and AUCR^ROC of VEGF/IFN-γ ratio （88,7%, 99,8%, 94,4%, 0.96 respectively） were higher than those of CEA （67.8%, 96.1%, 82,4%, 0.78 respectively） and VEGF （81,5%, 84,3%, 82.9%, 0.79 respectively）. The sensitivity, specificity, accuracy and AUCR^ROC of IFN-γ （85.7%, 96,4%, 90.9%, 0.94 respectively） were higher than those of ADA （80,2%, 87,6%, 83.8%, 0,81 respectively）. It was concluded that VEGF/IFN-γ ratio and IFN-γ could be used as valuable parameters for the differential diagnosis of malignant pleural effusion and tuberculous pleural effusion.展开更多

The purpose of this study was to evaluate these factors. METHODS: From March 2003 to May 2005, 228 consecutive patients with primary liver cancer underwent hepatectomy in our department were evaluated retrospectively to identify factors related to postoperative pleural effusion. RESULTS: Among the 228 patients, postoperative pleural effusions arose in 58 (25.4%). Univariate analysis showed significant differences in postoperative ascites, subphrenic collection, Pringle manoeuvre length, drainage amount on postoperative day 1, albumin level on postoperative day 7, alanine aminotransferase (ALT) level on postoperative days I and 3, prealbumin level on postoperative days 3 and 7, and tumor size (P<0.05). Ordinal regression analysis revealed that subphrenic collection, drainage on postoperative day I and ALT plus prealbumin on postoperative days I and 3 were statistically significantly related to postoperative pleural effusion (P<0.05). CONCLUSION: Subphrenic collection and operative injury to the liver appeared to be significantly related to pleural effusion after hepatectomy for primary liver cancer.展开更多

The risk factors, prevention and management of postoperative pleural effusion in patients with primary liver cancer (PLC) who have undergone hepatectomy and the value of the argon beam coagulator (ABC) for the prevention of pleural effusion are studied. METHODS:A total of 523 patients with PLC at our institution who had had right hepatectomy from July 2000 to June 2004 were studied retrospectively. Comparative analysis was made to identify the factors contributing to postoperative pleural effusion and the efficacy of various managements. RESULTS:Of the 523 patients whose livers were dissociated using argon beam cutting and/or coagulation, 20(3.8%) developed pleural effusions;whereas in the other 467 patients underwent hepatectomy with suture ligation of the diaphragmatic secondary wound surface during the same period, 49(10.5%) had pleural effusion (P<0.01). The factors contributing to postoperative pleural effusion included subphrenic collection, postoperative hepatic insufficiency with ascites, duration of hepatic occlusion and underlying cirrhosis. CONCLUSIONS: Dissociation of the liver by argon beam cutting and/or coagulation can save suture ligation of the diaphragmatic secondary wound surface and may also prevent postoperative pleural effusion. Pleural drainage using an indwelling central-venous-catheter (CVC) in the pleural cavity is safe and efficacious.展开更多

Methods Ninety-five consecutive patients diagnosed with univentricular heart underwent extracardiac connection using Gore-Tax conduits at the Department of Children’s Heart Centre,Justus-Liebig-University Giessen in Germany from June 1996 to July 2007. The outcome measures were duration and volume of chest tube drainage after surgical intervention. The investigated factors included age and weight at the time of operation,anatomical diagnosis,preoperative oxygen saturation,mean pulmonary artery pressure,ventricular end-diastolic pressure,fenestration,cardiopulmonary bypass time,conduit size,postoperative pulmonary artery pressure,administration of angiotensin-converting enzyme inhibitors,and postoperative infection. Associations between these factors and persistent pleural effusion after the extracardiac Fontan procedure were analyzed. Results Every patient suffered postoperative effusion. The median duration of postoperative chest tube drainage was 9 days (range,3-69 days),and the median volume was 12 mL·kg-1·d-1 (range,2.0-37.5 mL·kg-1·d-1). Thirty-seven (38.9%) patients had pleural drainage for more than 15 days,and the volume in 35 (36.8%) patients exceeded 25 mL·kg-1·d-1. Nineteen (20%) patients required placement of additional chest tubes for re-accumulation of pleural effusion after removal of previous chest tubes. Fifteen (17.8%) patients were hospitalized again due to pleural effusion after discharge. The median length of hospital stay after the operation was 14 days (range,4-78 days). Multivariate analysis results showed that non-fenestration,low preoperative oxygen saturation,and postoperative infections were independent risk factors for prolonged duration of pleural drainage (P<0.05). Long cardiopulmonary bypass time,non-fenestration,small conduit size,and low preoperative oxygen saturation were independent risk factors for excessive volume of pleural drainage (P<0.05).Conclusions For reduing postoperative duration and volume of pleural drainage following Fontan procedure,it seems to be important to improve the preoperative oxygen saturation,use large size of conduit,shorten cardiopulmonary bypass time,and make fenestration during the operation,as well as avoid postoperative infections.展开更多

The follow-up clinical data on patients who received crizotinib treatment were recorded.Results： Of the 313 MPE samples, 27（8.6%） were confirmed as ALK expression-positive, and the Ventana IHC ALK（D5F3）-positive rate was 17.3%（27/156） in wild-type epidermal growth factor receptor（EGFR） MPE samples. Twenty-three of the 27 IHC ALK（D5F3）-positive samples were positive by FISH. Of the 11 Ventana IHC ALK（D5F3）-positive patients who received crizotinib therapy, 2 patients had complete response（CR）, 5 had partial response（PR） and 3 had stable disease（SD）.Conclusions： The ALK gene expression status detected by the Ventana IHC ALK（D5F3） platform in MPE samples may predict tumor responsiveness to crizotinib in Chinese patients with advanced lung adenocarcinoma.展开更多

文摘BACKGROUND Ovarian hyperstimulation syndrome(OHSS)is a life-threatening complication that can occur in the luteal phase or early pregnancy after controlled ovarian stimulation.This case report highlights a unique manifestation of OHSS involving pleural effusion(PE)in a patient without identifiable risk factors.CASE SUMMARY A 39-year-old woman who underwent controlled ovarian hyperstimulation for an in vitro fertilization(IVF)cycle experienced dyspnea on the eleventh day of post oocyte retrieval.The diagnosis was severe OHSS with a unique manifestation of PE without ascites.Clinical management involved fluid balance and treatment with albumin,furosemide,thromboembolic prophylaxis,and thoracentesis.A continued drainage of the pleural cavity was performed.The patient had a favo-rable outcome,and a dichorionic diamniotic gestation passed without incident.CONCLUSION OHSS and its potential complications can include respiratory distress and PE,as well as thromboembolic disorders.
文摘BACKGROUND Although inflammatory diseases commonly affect the pleura and pleural space,their mechanisms of action remain unclear.The presence of several mediators emphasizes the concept of pleural inflammation.Adenosine deaminase(ADA)is an inflammatory mediator detected at increased levels in the pleural fluid.AIM To determine the role of total pleural ADA(P-ADA)levels in the diagnosis of pleural inflammatory diseases.METHODS 157 patients with inflammatory pleural effusion(exudates,n=124,79%)and noninflammatory pleural effusion(transudates,n=33,21%)were included in this observational retrospective cohort study.The P-ADA assay was tested using a kinetic technique.The performance of the model was evaluated using the area under the receiver operating characteristic(ROC)curve(AUC).The ideal cutoff value for P-ADA in pleural inflammation was determined using the Youden index in the ROC curve.RESULTS The transudates included congestive heart failure(n=26),cirrhosis of the liver with ascites(n=3),chronic renal failure(n=3),and low total protein levels(n=1).The exudate cases included tuberculosis(n=44),adenocarcinoma(n=37),simple parapneumonic effusions(n=15),complicated parapneumonic effusions/empyema(n=8),lymphoma(n=7),and other diseases(n=13).The optimal cutoff value of P-ADA was≥9.00 U/L.The diagnostic parameters as sensitivity,specificity,positive and negative predictive values,positive and negative likelihood values,odds ratio,and accuracy were 77.69(95%CI:69.22-84.75);68.75(95%CI:49.99-83.88);90.38 and 44.90(95%CI:83.03-95.29;30.67-59.77);2.48 and 0.32(95%CI:2.21-11.2;0.27-0.51);7.65(95%CI:0.78-18.34),and 75.82(95%CI:68.24-82.37),respectively(χ^(2)=29.51,P=0.00001).An AUC value of 0.8107(95%CI:0.7174-0.8754;P=0.0000)was clinically useful.The Hosmer-Lemeshow test showed excellent discrimination.CONCLUSION P-ADA biomarker has high diagnostic performance for pleural inflammatory exudates.
文摘BACKGROUND Postoperative complications such as atrial fibrillation and pericardial effusion are frequent after coronary artery bypass grafting(CABG),contributing to increased morbidity and prolonged hospital stays.Posterior pericardiotomy(PP),a surgical technique involving incision of the posterior pericardium to allow drainage,has been suggested as a preventive measure.However,its overall efficacy and safety profile,including potential risks like pleural effusion,require comprehensive evaluation amid varying study qualities.We hypothesized that PP reduces key post-CABG complications compared to standard care.AIM To determine the efficacy of PP in reducing postoperative complications following CABG.METHODS This systematic review and meta-analysis included randomized controlled trials(RCTs)from PubMed,Cochrane,ClinicalTrials.gov,and Ovid,comparing PP vs no PP in adult CABG patients.Studies were conducted in tertiary care hospital settings.Twenty RCTs with 5331 participants were selected based on predefined inclusion criteria.The intervention involved intraoperative PP.Primary outcome was postoperative atrial fibrillation(POAF);secondary outcomes included effusions,tamponade,hospital/intensive care unit stay,and bleeding revisions.Risk ratios(RRs),mean differences,and 95%confidence intervals(CIs)were calculated using random-effects models;heterogeneity assessed via I^(2) statistic.RESULTS Twenty RCTs analyzed 5331 patients(2665 with PP vs 2666 without).PP significantly lowered POAF(10%vs 21%;RR=0.48,95%CI:0.36-0.65,P<0.00001;I^(2)=70%),cardiac tamponade(0.5%vs 3%;RR=0.16,95%CI:0.08-0.34,P<0.00001;I^(2)=0%),early pericardial effusion(2%vs 6%;RR=0.31,95%CI:0.14-0.68,P=0.004;I^(2)=96%),and late pericardial effusion(1%vs 9%;RR=0.11,95%CI:0.05-0.21,P<0.00001;I^(2)=0%).Hospital stay decreased(mean difference=-1.23 days,95%CI:-1.87 to-0.59,P=0.0002;I^(2)=85%).Pleural effusion risk increased(25%vs 17%;RR=1.46,95%CI:1.21-1.76,P<0.0001;I^(2)=0%).No significant effects on mortality(RR=0.92,95%CI:0.48-1.76,P=0.80;I^(2)=0%),intensive care unit stay,or bleeding revisions.CONCLUSION PP effectively reduces POAF,pericardial effusions,tamponade,and hospital stay in CABG patients,though it increases pleural effusion risk and shows heterogeneity in some outcomes.
文摘This editorial underscores the importance of Maranhão et al’s study,which investigates pleural adenosine deaminase(P-ADA)as a biomarker for inflammatory pleural effusions.Despite advances in imaging,distinguishing between inflammatory and non-inflammatory causes of pleural effusion remains a diagnostic challenge.The authors conducted a rigorous retrospective cohort analysis of 157 patients(124 with inflammatory exudates and 33 with non-inflammatory transudates),establishing a robust cutoff value of P-ADA≥9.00 U/L for diagnosing inflammatory diseases using receiver operating characteristic curve analysis and internal statistical calibration.This is the first study to define a standardized PADA threshold in a Brazilian cohort,addressing previous inconsistencies in cutoff values.Furthermore,the authors delved into the pathophysiological mechanisms underlying elevated P-ADA,linking it to purinergic signaling pathways and immune cell activation,particularly emphasizing the role of ADA2 isoforms in macrophages and lymphocytes.Their findings support P-ADA as a non-invasive,cost-effective biomarker for early diagnosis,treatment stratification,and minimizing the need for invasive procedures such as thoracentesis.This has particular relevance in resource-limited settings,where streamlined diagnostics can reduce healthcare costs and improve patient outcomes.Future studies must prioritize global validation,explore the integration of adenosine deaminase with additional biomarkers(e.g.,interleukin 6,C-reactive protein),and support the development of point-of-care technologies.
文摘Pleural effusion,characterized by the accumulation of fluid in the pleural space,poses significant challenges in clinical practice,especially in determining whether it belongs to the inflammatory exudates or non-inflammatory transudates.Adenosine deaminase(ADA),an enzyme primarily produced by immune cells,particularly lymphocytes,increase in response to inflammatory conditions,including tuberculosis and malignancies.Elevated ADA levels in pleural have been shown to correlate with inflammatory exudates,making it a valuable biomarker for dif-ferentiating between inflammatory and non-inflammatory effusions.Moreover,numerous studies have demonstrated the treatment function of ADA in inflammation-related pleural effusion syndrome.Recently,research has established the values for the implication of ADA in diagnosing and managing pleural disease.Based on these findings,ADA becomes a reliable,non-invasive marker for early diagnosis and the appropriate treatment for pleural inflammation,ultimately improving patient outcomes.

文摘Background:The diagnosis of tuberculous pleurisy(TP)presents a significant challenge due to the low bacterial load in pleural effusion(PE)samples.Cell-free Mycobacterium tuberculosis DNA(cf-TB)in PE samples is considered an optimal biomarker for diagnosing TP.This study aimed to evaluate the applicability of cf-TB testing across diverse research sites with a relatively large sample size.Methods:Patients suspected of TP and presenting with clinical symptoms and radiological evidence of PE were consecutively enrolled by treating physicians from 11 research sites across 6 provinces in China between April 2020 and August 2022.Following centrifugation,sediments obtained from PE were used for Xpert MTB/RIF(Xpert)and mycobacterial culture,while the supernatants were subjected to cf-TB testing.This study employed a composite reference standard to definite TP,which was characterized by any positive result for Mycobacterium tuberculosis(MTB)through either PE culture,PE Xpert,or pleural biopsy.Results:A total of 1412 participants underwent screening,and 1344(95.2%)were subsequently enrolled in this study.Data from 1241(92.3%)participants were included,comprising 284 with definite TP,677 with clinically diagnosed TP,and 280 without TP.The sensitivity of cf-TB testing in definite TP was 73.6%(95%CI 68.2%-78.4%),significantly higher than both Xpert(40.8%,95%CI 35.3%-46.7%,P<0.001)and mycobacterial culture(54.2%,95%CI 48.4%-59.9%,P<0.001).When clinically diagnosed TP was incorporated into the composite reference standard for sensitivity analysis,cf-TB testing showed a sensitivity of 46.8%(450/961,95%CI 43.7%-50.0%),significantly higher than both Xpert(12.1%,116/961,95%CI 10.2%-14.3%,P<0.001)and mycobacterial culture(16.0%,154/961,95%CI 13.8%-18.5%,P<0.001).The specificities of cf-TB testing,Xpert,and mycobacterial culture were all 100.0%.Conclusions:The performance of cf-TB testing is significantly superior to that of Xpert and mycobacterial culture methods,indicating that it can be considered as the primary diagnostic approach for improving TP detection.Trial registration:The trial was registered on Chictr.org.cn(ChiCTR2000031680,https://www.chictr.org.cn/showproj.html?proj=49316).
文摘This paper presents a novelmulticlass systemdesigned to detect pleural effusion and pulmonary edema on chest Xray images,addressing the critical need for early detection in healthcare.A new comprehensive dataset was formed by combining 28,309 samples from the ChestX-ray14,PadChest,and CheXpert databases,with 10,287,6022,and 12,000 samples representing Pleural Effusion,Pulmonary Edema,and Normal cases,respectively.Consequently,the preprocessing step involves applying the Contrast Limited Adaptive Histogram Equalization(CLAHE)method to boost the local contrast of the X-ray samples,then resizing the images to 380×380 dimensions,followed by using the data augmentation technique.The classification task employs a deep learning model based on the EfficientNet-V1-B4 architecture and is trained using the AdamW optimizer.The proposed multiclass system achieved an accuracy(ACC)of 98.3%,recall of 98.3%,precision of 98.7%,and F1-score of 98.7%.Moreover,the robustness of the model was revealed by the Receiver Operating Characteristic(ROC)analysis,which demonstrated an Area Under the Curve(AUC)of 1.00 for edema and normal cases and 0.99 for effusion.The experimental results demonstrate the superiority of the proposedmulti-class system,which has the potential to assist clinicians in timely and accurate diagnosis,leading to improved patient outcomes.Notably,ablation-CAM visualization at the last convolutional layer portrayed further enhanced diagnostic capabilities with heat maps on X-ray images,which will aid clinicians in interpreting and localizing abnormalities more effectively.
文摘BACKGROUND Plasma cell myeloma(PCM)is characterized by hypercalcemia,renal impairment,anemia,and bone destruction.While pleural effusion,ascites,abdominal pain,and bloody stool are common manifestations of lung disease or gastrointestinal disorders,they are rarely observed in patients with PCM.CASE SUMMARY A 66-year-old woman presented with complaints of recurrent chest tightness,wheezing,and abdominal bloating accompanied by bloody stools.Computed tomography revealed pleural effusion and ascites.Pleural effusion tests showed inflammation,but the T-cell spot test and carcinoembryonic antigen were negative.Endoscopy showed colonic mucosal edema with ulcer formation and local intestinal lumen stenosis.Echocardiography revealed enlarged atria and reduced left ventricular systolic function.The diagnosis remained unclear.Further testing revealed elevated blood light chain lambda and urine immunoglobulin levels.Blood immunofixation electrophoresis was positive for immunoglobulin G lambda type.Smear cytology of the bone marrow showed a high proportion of plasma cells,accounting for about 4.5%.Histopathological examination of the bone marrow suggested PCM.Flow cytometry showed abnormal plasma cells with strong expression of CD38,CD138,cLambda,CD28,CD200,and CD117.Fluorescence in situ hybridization gene testing of the bone marrow suggested 1q21 gene amplification,but cytogenetic testing showed no clonal abnormalities.Colonic mucosa and bone marrow biopsy tissues were negative for Highman Congo red staining.The patient was finally diagnosed with PCM.CONCLUSION A diagnosis of PCM should be considered in older patients with pleural effusion,ascites,and multi-organ injury.
文摘Background and Aims While chest X-ray (CXR) has been a conventional tool in intensive care units (ICUs) to identify lung pathologies, computed tomography (CT) scan remains the gold standard. Use of lung ultrasound (LUS) in resource-rich ICUs is still under investigation. The present study compares the utility of LUS to that of CXR in identifying pulmonary edema and pleural effusion in ICU patients. In addition, consolidation and pneumothorax were analyzed as secondary outcome measures. Material and Methods This is a prospective, single centric, observational study. Patients admitted in ICU were examined for lung pathologies, using LUS by a trained intensivist;and CXR done within 4 hours of each other. The final diagnosis was ascertained by an independent senior radiologist, based on the complete medical chart including clinical findings and the results of thoracic CT, if available. The results were compared and analyzed. Results Sensitivity, specificity and diagnostic accuracy of LUS was 95%, 94.4%, 94.67% for pleural effusion;and 98.33%, 97.78%, 98.00% for pulmonary edema respectively. Corresponding values with CXR were 48.33%, 76.67%, 65.33% for pleural effusion;and 36.67%, 82.22% and 64.00% for pulmonary edema respectively. Sensitivity, specificity and diagnostic accuracy of LUS was 91.30%, 96.85%, 96.00% for consolidation;and 100.00%, 79.02%, 80.00% for pneumothorax respectively. Corresponding values with CXR were 60.87%, 81.10%, 78.00% for consolidation;and 71.3%, 97.20%, 96.00% for pneumothorax respectively. Conclusion LUS has better diagnostic accuracy in diagnosis of pleural effusion and pulmonary edema when compared with CXR and is thus recommended as an effective alternative for diagnosis of these conditions in acute care settings. Our study recommends that a thoracic CT scan can be avoided in most of such cases.
文摘Background: Malignant pleural effusion (MPE) is the most common complication of advanced NSCLC. Infusion chemotherapy is currently one of the most common intracavitary treatments for MPE. Unfortunately, there is no definitive consensus on which intracavitary infusion drug has the best effect on the treatment. The use of de-platinum-based thoracic perfusion therapy can offer several advantages, such as reducing drug toxicity and contributing to an improvement in patients’ physical condition. Therefore, this study was to investigate the clinical efficacy and safety of de-platinum-based pleural perfusion bevacizumab combined with Brucea Javanica Oil Emulsion Injection (BJOEI) in the treatment of malignant pleural effusion in advanced lung adenocarcinoma. Methods: A total of 60 patients diagnosed with lung adenocarcinoma and malignant pleural effusion were selected from Binzhou People’s Hospital, Shandong Provincial Cancer Hospital, and Binzhou Central Hospital between June 2022 and May 2024, with 30 cases treated in each group. The study was divided into two groups: the treatment group received bevacizumab injection perfusion in combination with intravenous infusion of Brucea Javanica Oil Emulsion Injection (BJOEI), while the control group received bevacizumab injection combined with cisplatin perfusion. To analyze the data and evaluate their efficacy and adverse reactions, such as disease control rate (DCR), overall response rate (ORR), Karnofsky Performance Status (KPS), vascular endothelial growth factor (VEGF), and so forth. Results: Following the treatment, the quality of life scores in both groups exhibited an increase compared to pre-treatment levels. Moreover, the enhancement observed in the treatment group was deemed statistically significant (P = 0.007). Following treatment, The expression of VEGF in the pleural effusion of both groups of patients was significantly decreased, and the disparity within the same group was found to be statistically significant (P P χ2 = 0.317, P = 0.573;χ2 = 0.218, P = 0.640). A stratified analysis of factors influencing the ORR revealed that the ORR in both groups exhibited statistical significance when the previous KPS score was below 70 (χ2 = 5.850, P = 0.016). The main adverse reactions in both groups included nausea, vomiting, gastrointestinal reactions, fatigue, and hematological toxicity. Among them, there was a statistically significant difference in the occurrence of gastrointestinal reactions and fatigue between the two groups (χ2 = 8.148, P = 0.004;χ2 = 6.696, P = 0.010). Conclusion: Bevacizumab, when combined with Brucea Javanica Oil Emulsion Injection (BJOEI), demonstrates noteworthy efficacy in treating malignant pleural effusion. This combination therapy reduces VEGF expression, in which the reduction supports the efficacy of thoracic perfusion and is associated with minimal adverse reactions, contributing to an improvement in patients’ physical condition and overall clinical tolerability, especially for the poor physique, especially in the elderly and KPS score is less than 70. Therefore, it can be considered a recommended approach for managing malignant pleural effusion, offering significant clinical value.

文摘In order to investigate the clinical value of vascular endothelial growth factor （VEGF） combined with interferon-γ （IFN-γ） in diagnosing malignant pleural effusion and tuberculous pleural effusion, 42 cases of malignant pleural effusion and 45 cases of tuberculous pleural effusion in Tongji Hospital, from March 2004 to May 2005, were included, The carcinoembryonic antigen （CEA）, VEGF and IFN-γ levels of pleural effusion were detected by using ELISA, and adenosine deaminase （ADA） activity was determined by using enzyme kinetic analytical method. The sensitivity, specificity, accuracy and area under the curve （AUCR^ROC） of CEA and VEGF, VEGF/IFN-γ ratio, ADA and IFN-γ were measured by receiver operating characteristic curve （ROC）, The results showed that CEA, VEGF levels and VEGF/IFN-γ ratio were significantly higher and the ADA and IFN-γ levels were significantly lower in malignant group than those in tuberculous group （P〈0,01）, The sensitivity, specificity, accuracy and AUCR^ROC of VEGF/IFN-γ ratio （88,7%, 99,8%, 94,4%, 0.96 respectively） were higher than those of CEA （67.8%, 96.1%, 82,4%, 0.78 respectively） and VEGF （81,5%, 84,3%, 82.9%, 0.79 respectively）. The sensitivity, specificity, accuracy and AUCR^ROC of IFN-γ （85.7%, 96,4%, 90.9%, 0.94 respectively） were higher than those of ADA （80,2%, 87,6%, 83.8%, 0,81 respectively）. It was concluded that VEGF/IFN-γ ratio and IFN-γ could be used as valuable parameters for the differential diagnosis of malignant pleural effusion and tuberculous pleural effusion.
文摘BACKGROUND: Pleural effusion frequently complicates hepatectomy and multiple factors contribute to its development following hepatectomy for primary liver cancer. The purpose of this study was to evaluate these factors. METHODS: From March 2003 to May 2005, 228 consecutive patients with primary liver cancer underwent hepatectomy in our department were evaluated retrospectively to identify factors related to postoperative pleural effusion. RESULTS: Among the 228 patients, postoperative pleural effusions arose in 58 (25.4%). Univariate analysis showed significant differences in postoperative ascites, subphrenic collection, Pringle manoeuvre length, drainage amount on postoperative day 1, albumin level on postoperative day 7, alanine aminotransferase (ALT) level on postoperative days I and 3, prealbumin level on postoperative days 3 and 7, and tumor size (P<0.05). Ordinal regression analysis revealed that subphrenic collection, drainage on postoperative day I and ALT plus prealbumin on postoperative days I and 3 were statistically significantly related to postoperative pleural effusion (P<0.05). CONCLUSION: Subphrenic collection and operative injury to the liver appeared to be significantly related to pleural effusion after hepatectomy for primary liver cancer.
文摘Postoperative pleural effusion occurs frequently after hepatectomy. The risk factors, prevention and management of postoperative pleural effusion in patients with primary liver cancer (PLC) who have undergone hepatectomy and the value of the argon beam coagulator (ABC) for the prevention of pleural effusion are studied. METHODS:A total of 523 patients with PLC at our institution who had had right hepatectomy from July 2000 to June 2004 were studied retrospectively. Comparative analysis was made to identify the factors contributing to postoperative pleural effusion and the efficacy of various managements. RESULTS:Of the 523 patients whose livers were dissociated using argon beam cutting and/or coagulation, 20(3.8%) developed pleural effusions;whereas in the other 467 patients underwent hepatectomy with suture ligation of the diaphragmatic secondary wound surface during the same period, 49(10.5%) had pleural effusion (P<0.01). The factors contributing to postoperative pleural effusion included subphrenic collection, postoperative hepatic insufficiency with ascites, duration of hepatic occlusion and underlying cirrhosis. CONCLUSIONS: Dissociation of the liver by argon beam cutting and/or coagulation can save suture ligation of the diaphragmatic secondary wound surface and may also prevent postoperative pleural effusion. Pleural drainage using an indwelling central-venous-catheter (CVC) in the pleural cavity is safe and efficacious.

文摘BACKGROUND Pleural effusions occur for various reasons,and their diagnosis remains challenging despite the availability of different diagnostic modalities.Medical thoracoscopy(MT)can be used for both diagnostic and therapeutic purposes,especially in patients with undiagnosed pleural effusion.AIM To assess the diagnostic efficacy and safety of MT in patients with pleural effusion of different causes.METHODS Between January 1,2012 and April 30,2021,patients with pleural effusion underwent MT in the Department of Respiratory Medicine,The Second Affiliated Hospital of Xi’an Jiaotong University(Shaanxi,China).According to the discharge diagnosis,patients were divided into malignant pleural effusion(MPE),tuberculous pleural effusion(TBPE),and inflammatory pleural effusion(IPE)groups.General information,and tuberculosis-and effusion-related indices of the three groups were analyzed.The diagnostic yield,diagnostic accuracy,performance under thoracoscopy,and complications of patients were compared among the three groups.Then,the significant predictive factors for diagnosis between the MPE and TBPE groups were analyzed.RESULTS Of the 106 patients enrolled in this 10-year study,67 were male and 39 female,with mean age of 57.1±14.184 years.Among the 74 thoracoscopy-confirmed patients,41(38.7%)had MPE,21 had(19.8%)TBPE,and 32(30.2%)were undiagnosed.Overall diagnostic yield of MT was 69.8%(MPE:75.9%,TBPE:48.8%,and IPE:75.0%,with diagnostic accuracies of 100%,87.5%,and 75.0%,respectively).Under thoracoscopy,single or multiple pleural nodules were observed in 81.1%and pleural adhesions in 34.0%with pleural effusions.The most common complication was chest pain(41.5%),followed by chest tightness(11.3%)and fever(10.4%).Multivariate logistic regression analyses showed effusion appearance[odds ratio(OR):0.001,95%CI:0.000-0.204;P=0.010]and carcinoembryonic antigen(OR:0.243,95%CI:0.081-0.728;P=0.011)as significant for differentiating MPE and TBPE,with area under the receiver operating characteristic curve of 0.977(95%CI:0.953-1.000;P<0.001).CONCLUSION MT is an effective,safe,and minimally invasive procedure with high diagnostic yield for pleural effusion of different causes.
文摘The occurrence of pancreatic pleural effusion,secondary to an internal pancreatic fistula,is a rare clinical syndrome and diagnosis is often missed.The key to the diagnosis is a dramatically elevated pleural fluid amylase.This pancreatic pleural effusion is also called a pancreatic pleural fistula.It is characterized by profuse pleural fluid and has a tendency to recur.Here we report a case of delayed internal pancreatic fistula with pancreatic pleural effusion emerging after splenectomy.From the treatment of this case,we conclude that the symptoms and signs of a subphrenic effusion are often obscure;abdominal computed tomography may be required to look for occult,intra-abdominal infection;and active conservative treatment should be carried out in the early period of this complication to reduce the need for endoscopy or surgery.
文摘BACKGROUND Meigs syndrome is a rare neoplastic disease characterized by the triad of benign solid ovarian tumor,ascites,and pleural effusion.In postmenopausal women with pleural effusions,ascites,elevated CA-125 level,and pelvic masses,the probability of disseminated disease is high.Nevertheless,the final diagnosis is based on its histopathologic features following surgical removal of a mass lesion.Here we describe a case of Meigs syndrome with pleural effusion as the initial manifestation.CASE SUMMARY A 52-year-old woman presented with a 2-mo history of dry cough and oppression in the chest and was admitted to our hospital due to recurrent pleural effusion and gradual worsening of dyspnea that had occurred over the previous month.Two months before admission,the patient underwent repeated chest drainage and empirical anti-tuberculosis treatment.However,the pleural fluid accumulation persisted,and the patient began to experience dyspnea on exertion leading to admission.A computed tomography scan of the chest,abdominal ultrasound,and magnetic resonance imaging confirmed the presence of right-sided pleural effusion and ascites with a right ovarian mass.Serum tumor markers showed raised CA-125.With a suspicion of a malignant tumor,the patient underwent laparoscopic excision of the ovarian mass and the final pathology was consistent with an ovarian fibrothecoma.On the seventh day postoperation,the patient had resolution of the right-sided pleural effusion.CONCLUSION Despite the relatively high risk of malignancy when an ovarian mass associated with hydrothorax is found in a patient with elevated serum levels of CA-125,clinicians should be aware about rare benign syndromes,like Meigs,for which surgery remains the preferred treatment.
文摘Objective To investigate the association between preoperative,operative,and postoperative factors and persistent pleural effusion after the extracardiac Fontan procedure. Methods Ninety-five consecutive patients diagnosed with univentricular heart underwent extracardiac connection using Gore-Tax conduits at the Department of Children’s Heart Centre,Justus-Liebig-University Giessen in Germany from June 1996 to July 2007. The outcome measures were duration and volume of chest tube drainage after surgical intervention. The investigated factors included age and weight at the time of operation,anatomical diagnosis,preoperative oxygen saturation,mean pulmonary artery pressure,ventricular end-diastolic pressure,fenestration,cardiopulmonary bypass time,conduit size,postoperative pulmonary artery pressure,administration of angiotensin-converting enzyme inhibitors,and postoperative infection. Associations between these factors and persistent pleural effusion after the extracardiac Fontan procedure were analyzed. Results Every patient suffered postoperative effusion. The median duration of postoperative chest tube drainage was 9 days (range,3-69 days),and the median volume was 12 mL·kg-1·d-1 (range,2.0-37.5 mL·kg-1·d-1). Thirty-seven (38.9%) patients had pleural drainage for more than 15 days,and the volume in 35 (36.8%) patients exceeded 25 mL·kg-1·d-1. Nineteen (20%) patients required placement of additional chest tubes for re-accumulation of pleural effusion after removal of previous chest tubes. Fifteen (17.8%) patients were hospitalized again due to pleural effusion after discharge. The median length of hospital stay after the operation was 14 days (range,4-78 days). Multivariate analysis results showed that non-fenestration,low preoperative oxygen saturation,and postoperative infections were independent risk factors for prolonged duration of pleural drainage (P<0.05). Long cardiopulmonary bypass time,non-fenestration,small conduit size,and low preoperative oxygen saturation were independent risk factors for excessive volume of pleural drainage (P<0.05).Conclusions For reduing postoperative duration and volume of pleural drainage following Fontan procedure,it seems to be important to improve the preoperative oxygen saturation,use large size of conduit,shorten cardiopulmonary bypass time,and make fenestration during the operation,as well as avoid postoperative infections.

文摘Objective： The relationship between anaplastic lymphoma kinase（ALK） expression in malignant pleural effusion（MPE） samples detected only by Ventana immunohistochemistry（IHC） ALK（D5F3） and the efficacy of ALKtyrosine kinase inhibitor therapy is uncertain.Methods： Ventana anti-ALK（D5F3） rabbit monoclonal primary antibody testing was performed on 313 cell blocks of MPE samples from Chinese patients with advanced lung adenocarcinoma, and fluorescence in situ hybridization（FISH） was used to verify the ALK gene status in Ventana IHC ALK（D5F3）-positive samples. The follow-up clinical data on patients who received crizotinib treatment were recorded.Results： Of the 313 MPE samples, 27（8.6%） were confirmed as ALK expression-positive, and the Ventana IHC ALK（D5F3）-positive rate was 17.3%（27/156） in wild-type epidermal growth factor receptor（EGFR） MPE samples. Twenty-three of the 27 IHC ALK（D5F3）-positive samples were positive by FISH. Of the 11 Ventana IHC ALK（D5F3）-positive patients who received crizotinib therapy, 2 patients had complete response（CR）, 5 had partial response（PR） and 3 had stable disease（SD）.Conclusions： The ALK gene expression status detected by the Ventana IHC ALK（D5F3） platform in MPE samples may predict tumor responsiveness to crizotinib in Chinese patients with advanced lung adenocarcinoma.

文摘Database-assisted global metabolomics has received growing attention due to its capability for unbiased identification of metabolites in various biological samples.Herein,we established a mass spectrometry(MS)-based database-assisted global metabolomics method and investigated metabolic distance between pleural effusion induced by tuberculosis and malignancy,which are difficult to be distinguished due to their similar clinical symptoms.The present method utilized a liquid chromatography(LC) system coupled with high resolution mass spectrometry(MS) working on full scan and data dependent mode for data acquisition.Unbiased identification of metabolites was performed through mass spectral searching and then confirmed by using authentic standards.As a result,a total of 194 endogenous metabolites were identified and 33 metabolites were found to be differentiated between tuberculous and malignant pleural effusions.These metabolites involved in tryptophan catabolism,bile acid biosynthesis,and β-oxidation of fatty acids,provided non-invasive biomarkers for differentiation of the pleural effusion samples with high sensitivity and specificity.
文摘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 ICUadmitted patient’s outcome.Finally,pleural effusion analysis can change the original diagnosis in some cases and redirect the management toward a different way.
