Rheumatologic and skeletal changes in acromegaly.
The anabolic functions of growth hormone (GH) and insulin-like growth factor-I (IGF-I) in cartilage and bone metabolism are important in the normal physiology of these tissues. The effects of chronic elevation of GH and IGF-I levels on bony structures produce the typical physical changes associated with acromegaly, whereas the effects on cartilage result in arthropathy, which is usually degenerative. This article presents an overview of the physiologic roles of GH and IGF-I in cartilage and bone metabolism, the clinical features of the degenerative arthropathy and other rheumatologic syndromes associated with acromegaly, effects of acromegaly on bone and mineral metabolism, and an unusual bone disease that is occasionally associated with acromegaly, the McCune-Albright syndrome.
