The acromegalic arthropathy.
Since the initial definition of acromegaly over 100 yr ago, extraordinary efforts have been made to control GH levels and the pituitary tumor. Criteria of cure have been evolving constantly and all previous statements should be revised according to modern criteria of disease control. Arthropathy is undoubtedly the most important cause of morbidity and functional disability of acromegaly, and bone alterations are highly characteristic of this syndrome. They involve theoretically all bones and, particularly, the appendicular and the axial skeleton. Radiographic changes at different joint sites are more common than symptoms related to their involvement. There is a progression in the acromegalic arthropathy, resembling that described for the acromegalic cardiomyopathy or for the acromegalic features at other organs, such as thyroid, breast and prostate. At early stage, cartilage hypertrophy predominates, and then degenerative changes start until osteoarthritis features occur. Arthropathy can be reversed by normalizing GH and IGF-I levels only at the initial stage. If the disease is left untreated for long time, the osteo-articular sequelae cannot be modified by any treatment of acromegaly.[1]References
