慢性阻塞性肺疾病的营养缺乏

慢性阻塞性肺疾病(COPD)是全世界范围内威胁人类健康的主要疾病,营养缺乏是COPD患者一个常见的问题,也是关系到其预后的一个独立危险因素.除体重下降外,人体测量指标结合实验室检查的综合判定指标及去脂体重、瘦体重等身体组成的分析对营养缺乏的判定具有一定的价值.目前对COPD营养缺乏的发病机制尚不完全清楚,研究表明除能量/代谢失衡、组织缺氧等因素外,系统炎症及瘦素、食欲素的相互调节可能也参与其发病.在COPD患者营养缺乏的治疗方面,除营养支持外,生长激素、睾丸酮等也可作为一种治疗措施.

Nutritional depletion in chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is one of the major diseases worldwide. Nutritional depletion is a common problem in COPD patients and also an independant predictor of survival in these patients. Many data are helpful for determining nutritional depletion, including anthropometric measurement, laboratory markers, body composition analysis (fat-free mass and lean mass), and body weight. The mechanism of nutritional depletion in patients with COPD is still uncertain. It may be associated with energy/metabolism imbalance, tissue hypoxia, systemic inflammation, and leptin/orexin disorders. In patients with nutritional depletion, growth hormone and testosterone can be used for nutritional therapy in addition to nutrition supplementation.
