慢性阻塞性肺病 (COPD) 患者的胸部肌肉质量减少. 夜间缺氧,或睡眠期间的低氧,与COPD患者的进一步肌肉损失 (肉症) 有关.
科学领域:
- 肺部医学 肺部医学
- 睡眠医学 睡眠医学
- 老年病的医生 老年病的医生
背景情况:
- 慢性阻塞性肺病 (COPD) 是一个主要的全球健康问题,在全球排名第三的死亡原因.
- 之前的研究表明,在COPD模型中,夜间低氧化症有助于骨肌肉损失 (肉症).
- 这项研究调查了COPD临床患者群体中夜间低氧化和肉症之间的关联.
研究的目的:
- 为了确定夜间低氧化症是否与被诊断为COPD的患者的肉症有关.
- 扩展对低氧化症诱导的肉症的临床前发现到人类队列中.
- 分析大量的睡眠注册表,以查看睡眠氧气水平与肌肉质量之间的相关性.
主要方法:
- 分析了479名COPD患者和275名对照患者的睡眠研究,不包括阻塞性睡眠呼吸暂停症患者 (呼吸暂停-呼吸暂停指数≥5).
- 通过CT扫描在睡眠研究的一年内量化胸部肌肉横截面积 (PMcsa).
- 根据调整的PMcsa残留物 (控制年龄,BMI,性别) 定义和使用平均夜间氧和度进行预测.
主要成果:
- 与对照组相比,COPD患者的胸肌指数 (PMI) 显著降低,男性减少了16.6%,女性减少了9.4%.
- 在COPD患者中,夜间低氧化症与PMI进一步下降,男性9.5%,女性11.2%,与没有夜间低氧化症的COPD患者相比.
- 这些减少在与夜间低氧血症的COPD患者与对照对象进行比较时更为明显,突出了睡眠期间低氧的有害影响.
结论:
- 在胸部肌肉中定义了sarcopenia,考虑了年龄,BMI和性别,建立了一个新的指标 (PMI).
- 患有COPD的患者表现出降低的PMI,而这种降低因夜间低氧化症而加剧.
- 需要进一步的研究,以确定保护性氧和值,以减轻或逆转与COPD夜间缺氧症相关的.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
