概括
囊性纤维化 (CF) 中的小血管损失始于童年,即使肺功能正常且早期治疗. 与较旧的CF调节剂不同,Trikafta治疗阻止了这种下降.
科学领域:
- 肺部医学
- 放射学
- 心肺成像检查
背景情况:
- 在囊性纤维化 (CF) 中的肺血管变化尚未完全理解.
- 衰老,疾病进展和调节剂疗法可能会影响CF肺血管.
研究的目的:
- 研究肺血管系统的形态变化.
- 评估年龄,疾病严重程度和调节器治疗对小血管体积的影响.
主要方法:
- 对65名CF患者进行了高分辨率CT扫描和肺功能测试.
- 计算了小血管体积与总血管体积 (BV5/ TBV%) 的比率.
- 通过对不同治疗组的BV5/ TBV%变化进行分析.
主要成果:
- 在CF患者的第一十年内,BV5/ TBV%下降,独立于FEV1%的下降.
- 这种下降与扩散和运动能力的减少有关.
- 在健康对照组或用Trikafta治疗的对照组中没有观察到显著的BV5/ TBV%下降.
结论:
- 在CF中,即使肺功能正常,小血管流失也会在生命的早期开始.
- 第一代调节器治疗没有阻止这种下降.
- 在CF中,Trikafta治疗似乎阻止了小血管损失的进展.

Cystic Fibrosis: Pathogenesis
360
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Pulmonary Hypertension: Classification and Pathogenesis
285
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...

Cystic Fibrosis: Management

Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.
