Lowering vascular calcification burden in chronic kidney disease: Is it possible?

Area of Science:

• Nephrology
• Cardiology
• Vascular Biology

Background:

• Chronic kidney disease (CKD) is associated with a high prevalence of atherosclerosis and arterial calcification, which cannot be solely explained by traditional cardiovascular risk factors.
• Coronary artery calcification magnitude is independently and inversely linked to renal function.
• CKD-specific factors like phosphate retention, calcium imbalance, and extended dialysis duration exacerbate vascular calcification.

Purpose of the Study:

• To explore the multifactorial nature of vascular calcification in CKD.
• To review current and potential therapeutic strategies for mitigating vascular calcification in CKD patients.

Main Methods:

• Review of existing literature on CKD, cardiovascular risk factors, and vascular calcification.
• Analysis of the impact of CKD-related factors on arterial calcification.
• Evaluation of current and emerging treatment options.

Main Results:

• Traditional cardiovascular risk factors are insufficient to explain the high rate of vascular calcification in CKD.
• CKD-specific issues significantly contribute to vascular calcification.
• Statins have shown no benefit in slowing vascular calcification progression in CKD.
• Emerging therapies like sodium thiosulfate show promise, but require further investigation.

Conclusions:

• Effective management of vascular calcification in CKD necessitates addressing both CKD and atherosclerotic risk factors.
• Current therapeutic strategies include phosphate binders, low-dose vitamin D, and calcimimetics.
• The efficacy of bisphosphonates remains uncertain, and further research is needed for newer agents.
