Skeletal complications in acromegaly

Area of Science:

• Endocrinology
• Bone Metabolism
• Rheumatology

Background:

• Growth hormone (GH) hypersecretion, often from pituitary tumors (somatotropinoma), causes gigantism or acromegaly.
• Excess GH and insulin-like growth factor 1 (IGF-1) impact bone metabolism, density, and microstructure.
• Acromegaly leads to unique joint disease, bone fragility, and systemic complications.

Purpose of the Study:

• To review the pathophysiology of bone and joint disease in acromegaly.
• To outline diagnostic approaches for acromegaly-related skeletal issues.
• To summarize current treatment strategies for acromegaly's skeletal manifestations.

Main Methods:

• Literature review of pathophysiology, diagnosis, and treatment.
• Synthesis of data on GH/IGF-1 effects on bone.
• Analysis of acromegaly's impact on joint disease and fracture risk.

Main Results:

• Acromegaly increases bone density but accelerates turnover, weakening microstructure.
• Vertebral fractures can occur despite normal bone mineral density due to impaired bone strength.
• Acromegaly causes distinct degenerative joint disease and systemic complications.

Conclusions:

• Acromegaly significantly alters bone metabolism, increasing fracture risk.
• Management requires addressing both hormonal excess and its skeletal consequences.
• Early diagnosis and treatment are crucial for improving quality of life and preventing complications.
