概括
胸部CT异常可以预测肺移植 (LTx) 后慢性肺异位功能障碍 (CLAD). 肺动脉狭窄,马赛克衰减,巩固和多发性溢出是早期CLAD检测和患者结果的关键指标.
科学领域:
- 肺部病理学 肺部病理学
- 放射学 放射学是一门学科.
- 移植医学 移植医学
背景情况:
- 慢性肺异位移植功能障碍 (CLAD) 是肺移植 (LTx) 后的一个主要并发症,表现为支气管炎消灭综合征 (BOS) 或限制性异位移植综合征 (RAS).
- 在呼吸系统显著下降之前预测CLAD对于及时干预和改善患者结果至关重要.
研究的目的:
- 调查早期和后续的胸部CT扫描异常对LTx后CLAD发展的预测价值.
- 确定与肺移植受体中CLAD,BOS,RAS和死亡率相关的特定CT发现.
主要方法:
- 一项回顾性单心研究分析了2015年1月至2018年12月期间118名肺移植接受者.
- 检查了初始 (CTi) 和随访 (CTf,LTx后≥9个月) 胸部CT扫描的异常.
- 考克斯回归分析确定了CLAD,BOS,RAS和死亡的风险因素,并进行了子组分析.
主要成果:
- 在初始CT (CTi) 上,肺动脉狭窄 (30-50%) 预测了CLAD (HR=4.6).
- 在随访CT (CTf) 时,马赛克衰减,巩固和多溢出与CLAD和BOS有关.
- 在CTf上,结合和流是死亡率的重要风险因素 (分别为p=0.029和p=0.001).
结论:
- 胸部CT成像在监测CLAD肺移植接受者的过程中发挥着至关重要的作用.
- 在CTI上早期识别肺动脉狭窄对于预测CLAD.很重要.
- 后续CT发现的巩固和多流是CLAD和死亡率的关键风险因素.

01:24Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
