Their proper diagnosis based on different parameters like pleural fluid protein, LDH, ADA, and cholesterol is very important. Light's criteria, though used as a standard method in differentiating pleural effusions as exudates and transudates, usually misidentifies 15%–20% of transudates as exudates. Hence, the role of other criteria like combined pleural fluid cholesterol and total protein in the differentiation of pleural fluid is studied in this study. The objectives of our study are to determine the role of combined pleural fluid cholesterol and total protein in the differentiation of exudates and transudates in cases presenting in Tribhuvan University Teaching Hospital.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>This is a single-centered, analytical, cross-sectional, observational study.

SHR-1501 also enhanced systemic immune responses, increasing CD8+ T cells and TEM populations in peripheral blood and spleen, with an early NK cell elevation on day 7 post-treatment. Single-cell analysis indicated that SHR-1501 promoted the activity of macrophages, increasing M1 macrophage proportions. Moreover, SHR-1501 enhanced the antitumor immune response by promoting pro-inflammatory changes across multiple cell types within the TME, including neutrophils, fibroblasts, and endothelial cells.

Diffuse lung lesions as a radiological presentation of ABPA are exceedingly rare, with no documented case in the literature. We present a case with asthma. High-resolution computed tomography (HRCT) of the chest revealed diffuse lung lesions. Additionally, arterial blood gas analysis revealed life-threatening acute Type II respiratory failure. Initially, there was suspicion of a mycobacterial infection. However, a subsequent diagnosis revealed the atypical presentation of ABPA. Finally, the patient's symptoms improved, and lung shadows were absorbed after undergoing mechanical ventilation with tracheal intubation and receiving methylprednisolone treatment.</p>","PeriodicalId":55247,"journal":{"name":"Clinical Respiratory Journal","volume":"19 7","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/crj.70115","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144673117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
