概括
胸腔液人体外皮膜分泌蛋白4 (HE4) 在区分恶性胸腔溢出 (MPE) 和良性胸腔溢出 (BPE) 中显示了中度的准确性. 然而,单纯的HE4不足以确定MPE的确诊.
科学领域:
- 肺液研究中的生物标志物.
- 诊断准确性的研究研究.
- 系统性审查和元分析.
背景情况:
- 腹液中的可溶性生物标志物为诊断恶性腹溢液 (MPE) 提供了一种具有成本效益,快速和最少侵入性的方法.
- 之前对肺部液体人体外皮膜分泌蛋白4 (HE4) 的MPE检测研究产生了不一致的结果.
- 这项研究系统地审查和元分析了多液HE4在区分MPE与良性多溢液 (BPE) 的诊断价值.
研究的目的:
- 评估腹腔液HE4的诊断性能.
- 使用HE4.4来区分恶性多流血 (MPE) 和良性多流血 (BPE).
- 提供关于HE4实用性的现有证据的综合分析.
主要方法:
- 在PubMed和Web of Science上对2025年5月1日之前发表的研究进行了系统的文献搜索.
- 数据提取包括研究特征,样本大小,HE4测定细节和诊断性能指标 (灵敏度,特异性,AUC).
- 使用QUADAS-2进行了质量评估,对聚合估计进行了双变量元分析,并进行了sROC曲线构造. 使用Deeks的测试来评估出版偏见.
主要成果:
- 包括7项包括1,216名患者 (592名MPE,624名BPE) 的研究.
- 对HE4的聚合灵敏度为0.59 (95% CI:0.43-0.74) 和聚合特异性为0.94 (95% CI:0.82-0.98).
- 曲线下的面积 (AUC) 为0.83 (95% CI:0.80-0.86),没有发现显著的出版偏差. 关键的偏见包括队列代表性和值选择.
结论:
- 腹液HE4在区分MPE和BPE方面表现出中等的价值.
- 仅仅HE4不足以证实或排除MPE.
- 可能需要进一步的研究来优化其在临床决策中的作用.

Pleural Effusion I: Introduction
4.0K
Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.
There are two main types of pleural effusion: transudative and exudative. They are differentiated using Light's...

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Pleura of the Lungs
6.5K
The lungs are nestled in a cavity, shielded by the pleura. The pleura, a form of serous membrane, wraps around each lung. This membrane arrangement consists of two layers: the visceral and parietal pleurae. The visceral pleura lines the surface of the lungIn contrast, the parietal pleura is the outer layer and contacts to the thoracic wall, the mediastinum, and the diaphragm. The hilum is the point of connection between the visceral and parietal layers. The space between the parietal and...

Endoscopic Studies II: Thoracocentesis
1.3K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
