[Arteriosklerosis and "osteoporosis" in patients with chronic kidney disease: same same, but different!]

Area of Science:

• Nephrology
• Cardiovascular Medicine
• Bone Metabolism

Background:

• Vascular calcifications and osteoporosis are common, impacting cardiovascular health.
• In chronic kidney disease (CKD), these disorders progress rapidly and have significant cardiovascular morbidity and mortality.
• The pathophysiology linking renal insufficiency to vascular and bone disorders is complex and interconnected.

Purpose of the Study:

• To explore the relationship between vascular calcifications and osteoporosis in CKD patients.
• To highlight the distinct pathophysiological mechanisms driving these conditions in CKD.
• To inform cautious clinical management of these disorders in CKD.

Main Methods:

• Review of current literature on vascular calcification and osteoporosis in CKD.
• Analysis of pathophysiological similarities and differences.
• Evaluation of current therapeutic strategies and their limitations.

Main Results:

• Vascular calcifications and bone formation share dynamic processes.
• CKD accelerates both vascular and bone disorders, driven by unique mechanisms.
• Standard treatments like calcium and bisphosphonates may need careful consideration in CKD.

Conclusions:

• Vascular and bone disorders in CKD, while related, require distinct management approaches.
• Current evidence-based therapies for these conditions in CKD lack proven efficacy on hard endpoints.
• Further research is needed for effective therapeutic options in CKD patients.
