The aim of this paper is to present the preliminary results of a joint project by SIBioC-AIPO working group on “Body cavities fluids”. The main purpose of the working group is to achieve a harmonized and shared diagnostic pathway related to pleural fluid (PF) analysis. The multistep project begins with a state of the art analysis. A survey, sent to both laboratory medicine personnel and pneumologists, was conducted between October and December 2016. The questionnaire (21 questions) was made available through the web-based SurveyMonkey platform. Overall, 408 replies were collected, 40.4% from laboratory medicine specialists, 3.2% from laboratory technicians, 49.3% from pneumologists and 7.1%…
Matrix metalloproteinases production in malignant pleural effusions after talc pleurodesis
2003
SUMMARY In this study we have evaluated the modifications of matrix metalloproteinases (MMPs) in malignant pleural fluids taken from patients suffering from lung cancer and treated with intrapleural talc instillation to induce pleurodesis. Furthermore, we have analysed the variations of some inflammatory mediators (C-reactive protein, α-1 antitrypsin) and of a protein (plasminogen) involved in MMP activation. In all patients the clinical improvement after talc pleurodesis was followed by a reduction in MMP-1, TIMP-1, C-reactive protein, α-1 antitrypsin and plasminogen activity. Furthermore, MMP-9 levels were variable; in fact, in some patients they were high at the beginning of treatment, i…
Free-Floating Mesothelial Cells in Pleural Fluid After Lung Surgery
2018
Objectives: The mesothelium, the surface layer of the heart, lung, bowel, liver and tunica vaginalis, is a complex tissue implicated in organ-specific diseases and regenerative biology; however, the mechanism of mesothelial repair after surgical injury is unknown. Previous observations indicated seeding of denuded mesothelium by free-floating mesothelial cells may contribute to mesothelial healing. In this study, we investigated the prevalence of mesothelial cells in pleural fluid during the 7 days following pulmonary surgery. Study design: Flow cytometry was employed to study pleural fluid of 45 patients after lung resection or transplantation. We used histologically validated mesothelial …
Lack of everolimus diffusion in pleural fluid during pleural progression of breast cancer: A case report
2020
Background We report here a case where no everolimus pleural diffusion was evidenced at the same time of pleural progression of a metastatic breast cancer treated with everolimus and exemestane. Case description A 69-year-old woman was diagnosed in October 2006 with stage III invasive ductal breast adenocarcinoma. After nine months of everolimus and exemestane treatment, she presented with a pleural progression. Everolimus concentration was measured in blood and in pleural fluid. Residual blood concentration was at 9.1 ng/mL, while no everolimus was observed in the pleural fluid. Management and outcome Due to inefficacy of everolimus in this patient, she was switched to palbociclib and fulv…
