Mesothelioma can be difficult to diagnose, and response to treatment is transient, even with recently adopted immune checkpoint inhibitor (ICI) combinations. Identification of mesothelioma-specific biomarkers could facilitate early diagnosis and tailor treatment strategies. Mesothelioma is characterized by frequent loss or alteration of the tumor suppressor genes <i>cyclin-dependent kinase inhibitor 2A</i> (<i>CDKN2A</i>) and <i>BRCA1-associated protein-1</i> (<i>BAP1</i>)<i>.</i> Accumulating data show these genes and/or their related protein products will be valuable tissue-based biomarkers for mesothelioma. Loss of BAP1, CDKN2A, p16, or methylthioadenosine phosphorylase provide pathologists with a reliable means of differentiating between mesothelioma and reactive mesothelial cell proliferations. This can aid diagnosis in difficult cases and is requisite for the identification of the new pathological entity malignant mesothelioma in situ. However, limited progress in identifying clinically useful soluble biomarkers in this cancer type has been made, with mesothelin remaining the benchmark. To date, results from studies to identify predictive biomarkers for ICI response have been disappointing. A recent retrospective study demonstrated BAP1 loss was predictive of improved survival following combination pemetrexed- and platinum-based chemotherapy. Validation of this result could have important clinical implications. Clinical trials aimed at targeting therapy based on biomarker expression are generally in the early phase setting, with overall results being moderate. The identification of biomarkers for mesothelioma remains a key research question due to their potential to improve patient outcomes in this deadly cancer.</p>","PeriodicalId":21727,"journal":{"name":"Seminars in respiratory and critical care medicine","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9794778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.</p>","PeriodicalId":21727,"journal":{"name":"Seminars in respiratory and critical care medicine","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9796322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its prevalence, it is only in the past 20 years that pleuralmedicine has been viewed as a specialty in its own right.1 With that, we have seen an exponential growth in research on its better management. Pleural disease is a centuries-old condition, with Hippocrates writing many landmark papers on pleural infection more than 25 centuries ago. Pleural effusion can be caused by more than 60 pathologies.2 It is a dynamic field as its incidence, diagnosis, and management constantly evolve with advances in medical management of the underlying conditions. In this issue of the Seminars of Respiratory and Critical Care Medicine, we aim to provide important updates on contemporary issues of key aspects of pleural diseases from leading experts around theworld. The enormous global economical and health care burden of pleural diseases are coming to light, as is concisely summarized by Vakil et al.3 New pleural disease entities are also described including pleural complications of COVID-19.4 With new developments of anticancer treatments, clinicians need to keep abreast of their implications on management of the associated malignant pleural effusions. Wong et al outline the impact of immunotherapy and antiangiogenic therapy on malignant effusion management,5 whereas Agrawal et al highlight the emerging intrapleural therapy for controlled of the effusions in pleural malignancies.6 Advances in biomarker discovery in mesothelioma have uncovered new clinical diagnostic tests of which clinicians should be aware.7 Manyof these targetmoleculesmay also have prognostic and therapeutic implications. Through a series of Expert Reviews, we also outline the current debates and controversies on management of spontaneous pneumothorax,8 a subject of pro–con debates in several major respiratory conferences and on advances in the care of parapneumonic effusions.9 Benign pleural effusions remain the most common cause of pleural effusions that clinicians will encounter. Porcel provides a state-ofthe-art review10 on their diagnosis and management. Muruganandan et al highlight the new advances in our understanding of why patients with pleural effusion are breathless, which is of significant interest to clinicians.11 Indwelling pleural catheters (IPCs) are now an established management of recurrent, especially malignant, pleural effusions. The focus of research has shifted from their advantages to how best to manage, or prevent, complications of IPC use.12 Sidhu et al outline the latest clinical guidelines and, where evidence is lacking, the expert opinions onbest care strategies. We trust that this series will equip clinicians with the most up-to-date knowledge on contemporary topics in pleural medicine. These advances in pleural disease will form the foundation of future, much-needed, research in clinical care of various pleural diseases.","PeriodicalId":21727,"journal":{"name":"Seminars in respiratory and critical care medicine","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10169804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
