[The changes of ghrelin, growth hormone, growth hormone releasing hormone and their clinical significances in patients with chronic obstructive pulmonary disease].

Objective: To investigate the changes of plasma ghrelin, growth hormone (GH) and growth hormone releasing hormone (GHRH) and gastric ghrelin in patients with chronic obstructive pulmonary disease (COPD) and to explore their clinical significances.

Methods: Plasma ghrelin, GH, GHRH, TNFα, IL-6 and C reactive protein (CRP) were measured in 40 COPD patients and 20 controls with chronic bronchitis. Correlated factors of plasma ghrelin, TNFα, IL-6, CRP were analyzed.
