概括
患有纤维性过敏性肺炎 (f-HP) 的患者比异常性肺纤维化 (IPF) 的生存率更好. 非纤维性HP (nf-HP) 显示出极好的生存率,HP患者随着时间的推移没有显著的肺功能下降.
科学领域:
- 肺部医学 肺部医学
- 呼吸系统疾病 呼吸系统疾病
- 放射学 放射学是一门学科.
背景情况:
- 慢性过敏性肺炎 (HP) 包括纤维化 (f-HP) 和非纤维化 (nf-HP) 形式.
- 异形性肺纤维化 (IPF) 是一种进展性纤维化肺病,预后不佳.
- 在临床管理中,HP亚型和IPF之间的比较生存率和肺功能数据对于临床管理至关重要.
研究的目的:
- 估计慢性HP (f-HP和nf-HP) 和IPF患者的生存率.
- 在这些患者群体中评估肺功能 (FVC,DLCO) 的纵向变化.
- 为了将放射学发现的预后值与HP的组织学诊断进行比较.
主要方法:
- 诊断HP涉及抗原暴露,高分辨率CT (HRCT),支气管支气管洗 (BAL) 和组织学.
- 根据HRCT的发现,HP被表型为纤维化 (f-HP) 或非纤维化 (nf-HP).
- IPF诊断主要基于HRCT;分析了生存率和肺功能 (FVC,DLCO).
主要成果:
- 五年生存率为IPF的23.9%,f-HP的72%,nf-HP的100% (p <0.0001).这些患者的5年生存率为23.9%,f-HP的72%,nf-HP的100% (p <0.0001).
- IPF显示FVC (-18.3%) 和DLCO (-10.2%) 的显著下降,而HP组的变化很小.
- 放射性表型与HP中的组织学具有很高的一致性 (89.6%),蜂巢预测IPF和f-HP的生存率较差.
结论:
- 与IPF相比,NF-HP和f-HP的生存率明显更好.
- 随着时间的推移,HP患者表现出稳定的肺功能,与IPF患者呈现逐渐下降的情况不同.
- 在HP中纤维化的放射性迹象可靠地诊断f-HP,并具有预后价值.

COPD: Pathogenesis and Clinical Features
265
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Pulmonary Hypertension: Classification and Pathogenesis
173
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Chronic Obstructive Pulmonary Disease-I: Introduction
2.8K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.
