约有 50 %ＣＯＰＤ住院病人其体重低于理想体重的 90 % ,而且大多有全身肌肉 (尤其是膈肌 )的消耗。目前认为低体重和肌肉消耗与ＣＯＰＤ病死率的增高和临床一般情况的恶化有关 ,而针对低体重的有效治疗措施有助于改善生存率。本研究旨在观察服用甲地孕酮 (ＭＡ)对ＣＯＰＤ病人 Approximately 50% of hospitalized patients with COPD have a body weight less than 90% of their ideal body weight, and most often have a depletion of the body muscles, especially the diaphragm. It is currently believed that low body weight and muscle depletion are associated with increased COPD mortality and general clinical deterioration, whereas effective treatment for low birth weight may help improve survival. This study aimed to observe the use of megestrol (MA) in COPD patients
