Vitamin K occurs in the diet as phylloquinone and menaquinones. Observational studies have shown that both phylloquinone and menaquinone intake might reduce cardiovascular disease CVD risk. However, the effect of vitamin K on vascular calcification is unknown. The aim of this study was to assess if menaquinone supplementation, compared to placebo, decreases vascular calcification in people with type 2 diabetes and known CVD. Femoral arterial calcification at baseline and 6 mo was measured with 18 sodium fluoride positron emission tomography 18 F-NaF PET scans as target-to-background ratios TBRs , a promising technique to detect active calcification.

Clinical Advances in Immunonutrition and Atherosclerosis: A Review

Atherosclerosis, the buildup of plaque inside arterial walls, is an early event in the development of cardiovascular disease CVD.

There is very limited evidence that nutrients influence the progression of atherosclerosis. Most research indicates that nutrients with antioxidant properties influence endothelial dysfunction , a condition that precedes atherosclerosis.

There is also evidence that some nutrients and phytochemicals reduce blood pressure and serum lipid levels , conditions that increase the risk of developing atherosclerosis. Atherosclerosis is a disease in which plaque builds up inside arterial walls. The formation of atherosclerotic plaque is an early event in the development of coronary heart disease CHD and progresses slowly over many years. The process begins with endothelial dysfunction , mainly in medium- and large-sized arteries.

At sites of endothelial dysfunction, damage to arterial walls may occur more quickly than repair. As a result, blood clotting proteins, immune cells, fat, and cholesterol accumulate at the site of damage, forming what is known as plaque. Ultimately, blood clots or pieces of plaque may become lodged in an artery, causing a heart attack or stroke.

Because atherosclerosis develops slowly over many years, there are several opportunities to intervene and slow its progression. See below for specific information about nutrients and dietary factors relevant to atherosclerosis. Peripheral arterial disease PAD - atherosclerosis in the arteries to the head, organs, arms and legs Coronary artery disease CAD - atherosclerosis in the arteries that supply blood to the heart Carotid artery disease - atherosclerosis in the arteries that supply blood to the brain.

Vitamin K-dependent proteins are involved in patho physiological calcification of the vasculature and the bones. Type 2 diabetes mellitus DM2 is associated with increased arterial calcification and increased fractures. CT scans were made at baseline and follow-up. Arterial calcification mass was quantified in several large arterial beds and a total arterial calcification mass score was calculated. BMD was assessed in all non-fractured thoracic and lumbar vertebrae. The vitamin K group had higher arterial calcification mass at baseline [median IQR : — vs — ] for the total arterial calcification mass. Future clinical trials may want to pre-select patients with very low vitamin K status and longer follow-up time might be warranted.

To assess the rate of matrix Gla-protein carboxylation in patients with small intestinal bacterial overgrowth SIBO and to decipher its association with subclinical atherosclerosis. Patients with suspected SIBO who presented with a low risk for cardiovascular disease and showed no evidence of atherosclerotic plaques were included in the study. A glucose breath test was performed in order to confirm the diagnosis of SIBO and vascular assessment was carried out by ultrasound examination. Plasma levels of the inactive form of MGP dephosphorylated-uncarboxylated matrix Gla-protein were quantified by ELISA and vitamin K2 intake was estimated using a food frequency questionnaire. Thirty-nine patients were included in the study.

Matrix Gla protein MGP is a major inhibitor of soft tissue calcification and contributes to preventing both intimal and medial vascular calcification. In support of this hypothesis, the procalcific effects of warfarin, an antagonist of vitamin K, on arterial calcification have been demonstrated in several clinical studies. There have been several studies showing the association of circulating levels of dp-ucMGP with vitamin K intake, vascular calcification, mortality, and CVD. However, additional larger prospective studies including randomized controlled trials are necessary to confirm the beneficial effects of vitamin K supplementation on CV health. Vitamin K is a fat-soluble vitamin that is composed of a 2-methyl-1,4-naphthoquinone ring and a side chain at the 3-carbon position varying in length and degree of saturation [ 1 ]. Vitamin K1 is predominantly found in green leafy vegetables and plant oils such as soybean, canola, and olive, whereas vitamin K2 is present in small amounts in fermented foods, milk products, meat, and cheese.

The Inhibitory Roles of Vitamin K in Progression of Vascular Calcification

Adriana J. Vitamins D and K are both fat-soluble vitamins and play a central role in calcium metabolism. Vitamin D promotes the production of vitamin K-dependent proteins, which require vitamin K for carboxylation in order to function properly.

Immunonutrient Supplementation View all 15 Articles. Atherosclerosis is a chronic low-grade inflammatory disease that affects large and medium-sized arteries and is considered to be a major underlying cause of cardiovascular disease CVD. The high risk of mortality by atherosclerosis has led to the development of new strategies for disease prevention and management, including immunonutrition. However, many of these correlations have been obtained in vitro and in experimental animals' models.

Atherosclerosis, the buildup of plaque inside arterial walls, is an early event in the development of cardiovascular disease CVD. There is very limited evidence that nutrients influence the progression of atherosclerosis. Most research indicates that nutrients with antioxidant properties influence endothelial dysfunction , a condition that precedes atherosclerosis. There is also evidence that some nutrients and phytochemicals reduce blood pressure and serum lipid levels , conditions that increase the risk of developing atherosclerosis.

Arterial stiffness is associated with cardiovascular risk, morbidity, and mortality. The present paper reviews the main vitamins related to arterial stiffness and enabling destiffening, their mechanisms of action, providing a brief description of the latest studies in the area, and their implications for primary cardiovascular prevention, clinical practice, and therapy. Despite inconsistent evidence for destiffening induced by vitamin supplementation in several randomized clinical trials, positive results were obtained in specific populations. The main mechanisms are related to antiatherogenic effects, improvement of endothelial function vitamins A, C, D, and E and metabolic profile vitamins A, B12, C, D, and K , inhibition of the renin-angiotensin-aldosterone system vitamin D , anti-inflammatory vitamins A, D, E, and K and antioxidant effects vitamins A, C, and E , decrease of homocysteine level vitamin B12 , and reversing calcification of arteries vitamin K. Vitamins A, B12, C, D, E, and K status is important in evaluating cardiovascular risk, and vitamin supplementation may be an effective, individualized, and inexpensive destiffening therapy.

Although vitamin K is a fat -soluble vitamin , the body stores very small amounts that are rapidly depleted without regular dietary intake. Perhaps because of its limited ability to store vitamin K, the body recycles it through a process called the vitamin K-epoxide cycle Figure 2. The vitamin K cycle allows a small amount of vitamin K to be reused many times for protein carboxylation , thus decreasing the dietary requirement. Briefly, vitamin K hydroquinone reduced form is oxidized to vitamin K epoxide oxidized form. The recycling of vitamin K epoxide oxidized form to hydroquinone reduced form is carried out by two reactions that reduce vitamin K epoxide KO to vitamin K quinone and then to vitamin K hydroquinone KH 2 ; Figure 2.

The Inhibitory Roles of Vitamin K in Progression of Vascular Calcification

Vascular Calcification View all 12 Articles. Calcium supplements are broadly prescribed to treat osteoporosis either as monotherapy or together with vitamin D to enhance calcium absorption. It is still unclear whether calcium supplementation significantly contributes to the reduction of bone fragility and fracture risk. Data suggest that supplementing post-menopausal women with high doses of calcium has a detrimental impact on cardiovascular morbidity and mortality.

Conclusions: A day course of vitamin K2 administration in patients with CKD stages may reduce the progression of atherosclerosis, but does not significantly affect the progression of calcification. Vitamin K2 significantly changes the levels of calcification promoters and inhibitors: dp-ucMGP, OC, and OPG.
