[Diabetes mellitus and bone]

Area of Science:

• Endocrinology
• Metabolic Bone Disease
• Diabetology

Background:

• Diabetic patients exhibit bone fragility, irrespective of bone mineral density.
• Diabetes-related bone disease is an emerging complication of diabetes.
• Factors implicated include advanced glycation end products (AGEs), collagen cross-linking, and impaired osteoblast function.

Purpose of the Study:

• To review the multifaceted effects of diabetes on bone metabolism.
• To elucidate the complex mechanisms underlying diabetes-related bone disease.

Main Methods:

• Literature review of recent evidence on diabetes and bone metabolism.
• Analysis of factors contributing to bone fragility in diabetic patients.

Main Results:

• Advanced glycation end products (AGEs) and homocysteine negatively impact osteoblasts and osteocytes.
• Diabetes is associated with low bone turnover, osteoblastic dysfunction, and microarchitectural abnormalities (e.g., cortical porosity, trabecular deterioration).
• Anti-diabetic medications can also influence bone metabolism.

Conclusions:

• Diabetes significantly complicates bone metabolism through various pathways.
• Understanding these complex mechanisms is crucial for managing bone health in diabetic patients.
