Biological Role of Vitamin K-With Particular Emphasis on Cardiovascular and Renal Aspects

Area of Science:

• Nephrology
• Biochemistry
• Cardiology

Background:

• Vitamin K (VK) is essential for calcium homeostasis and blood coagulation.
• Vascular calcification (VC) is a key factor in renal pathology.
• Matrix Gla protein (MGP), a potent VC inhibitor, is VK-dependent.

Purpose of the Study:

• To discuss the role of Vitamin K in chronic kidney disease (CKD).
• To explore the potential of Vitamin K supplementation in CKD patients.
• To examine the impact of anticoagulation therapy on VK status in CKD.

Main Methods:

• Review of existing literature on Vitamin K, CKD, vascular calcification, and MGP.
• Analysis of the relationship between VK deficiency, ucMGP levels, and cardiovascular risk in CKD.
• Discussion of the implications of anticoagulation therapy on VK status.

Main Results:

• CKD patients frequently exhibit Vitamin K deficiency, indicated by elevated ucMGP levels.
• VK deficiency is linked to an increased risk of cardiovascular events.
• Vitamin K supplementation may reduce VC and associated cardiovascular risks.

Conclusions:

• Vitamin K deficiency is prevalent in CKD and associated with adverse outcomes.
• VK supplementation is a potential therapeutic strategy to reduce VC and cardiovascular risk in CKD.
• Further research is needed to clarify the optimal use of VK and the effects of anticoagulation in CKD.
