Eur Respir J:但肺气肿并发特发性肺纤维化的功能和预后效应分析!

2017-07-08 xing.T MedSci原创

IPF患者的肺气肿对预后没有影响,超出了纤维化和肺气肿的相加程度所能解释的范畴。关于肺纤维化的位置,肺气肿的分布决定了肺气肿的功能效应。

近日,呼吸疾病领域权威杂志Eur Respir J上发表了一篇研究文章,该研究旨在利用视觉和计算机(CALIPER)为基础的断层扫描(CT)分析来探讨纤维化和肺气肿的结合是否比其部分对特发性肺纤维化(IPF)功能指数和预后的影响更大。

连续就诊的多学科IPF诊断患者(n=272)通过视觉评分和CALIPER来评估间质性肺疾病(ILD)程度。视觉得分肺气肿被分类为孤立性或混合性的肺纤维化。CT评分与功能指标用力肺活量(FVC)、肺一氧化碳弥散量(DLCO)、肺一氧化碳转移系数(KCO)、复合生理指数(CPI)和死亡率进行了评估。

肺气肿的存在和严重程度对生存没有影响。在对年龄、性别、吸烟状况和采用DLCO评估的基础严重程度以及结合的视觉肺气肿和ILD严重程度进行调整后,结果仍然一致。视觉肺气肿的定量分析表明相对正常的肺容积(FVC)导致肺纤维化内牵引性脱离地扩张气道,混合肺气肿的通气面积(P<0.0001),在孤立性肺气肿中对FVC没有独立的效应。相反,只有孤立性肺气肿(P<0.0001)可以降低气体转移(DLCO)。

IPF患者的肺气肿对预后没有影响,超出了纤维化和肺气肿的相加程度所能解释的范畴。关于肺纤维化的位置,肺气肿的分布决定了肺气肿的功能效应。

JAMA:肺减容线圈能有效地改善重度肺气肿患者的症状,但是短期成本较高

重度肺气肿的治疗方法十分有限。使用镍钛肺减容线圈的支气管镜介入治疗可诱导局部实质体积的减少并可恢复肺的弹性回缩。本研究旨在评估使用镍钛合金线圈治疗重度肺气肿的疗效、安全性、成本以及成本效益。
