[Diabetic osteopathies. 6. Treatment and its pitfalls]

Area of Science:

• Endocrinology
• Metabolic Bone Disease
• Diabetes Mellitus

Context:

• Diabetic osteopenia and osteomalacia are common complications of diabetes mellitus.
• Metabolic control significantly influences bone health in diabetic patients.
• Current treatments for diabetic bone disease vary in efficacy and impact on calcium and vitamin D metabolism.

Purpose:

• To evaluate the impact of different diabetes management strategies on bone metabolism.
• To assess the effectiveness of combined therapies (calcium, vitamin D, NaF, exercise) for diabetic osteoporoses.
• To examine the role of vitamin D and thiazide diuretics in managing diabetic osteomalacia and calciuria.

Summary:

• Optimal diabetes management, particularly with insulin, enhances calcium absorption and reduces urinary calcium excretion, benefiting bone health.
• Oral antidiabetics can negatively affect vitamin D and calcium metabolism, potentially worsening bone mineralization.
• Combined therapy with calcium, vitamin D, NaF, and exercise improves serum calcium levels and bone metabolism markers in diabetic osteoporoses, despite increased urinary calcium.
• High-dose vitamin D is the primary treatment for diabetic osteomalacia, improving metabolic control.
• Thiazide diuretics can reduce excessive urinary calcium but may slightly impair glucose tolerance.

Impact:

• Highlights the critical role of metabolic compensation in treating diabetic bone conditions.
• Provides insights into the differential effects of insulin versus oral antidiabetics on bone health.
• Suggests therapeutic strategies for managing diabetic osteopenias and osteomalacias, balancing bone health and metabolic control.
