Chronic renal disease is a worldwide major health problem, with increasing incidence, prevalence, high costs, and poor outcomes. 1 Mortality among patients with CKD and ESRD remains high due to its association with the occurrence of ischemic heart disease (IHD). 2 Numerous data show a close relationship between inflammation and cardiovascular morbidity and mortality. Hs-CRP is an important indicator and diagnostic tool for systemic inflammation. It has been found that Interleukin-6 and tumour necrosis factor-α are proinflammatory cytokines that can stimulate CRP synthesis in the liver. 3 All these biomarkers are very useful in the prediction of cardiovascular complications and mortality in ESRD patients. 4 Renal function impairment frequently leads to IHD. There are many traditional risk factors associated with IHD. Nowadays non-traditional CKD-specific risk factors for IHD appeared. Among the most important non-conventional risk factors are uremic toxins (UTs). Despite many studies either
Introduction: Matrix Gla protein (MGP) is a central calcification inhibitor of vascular wall. The biological activation of the calcification-inhibitory protein MGP can be achieved by simple administration of oral vitamin K. Aim: The study was conducted to assess the effect of vitamin k supplementation on vascular calcification and to evaluate its effect on MGA in hemodialysis patients. Materials and Methods: Forty adult patients with end stage renal disease (ESRD) on regular hemodialysis sessions, thrice weekly, were enrolled in the study and were randomly assigned into two groups. Vitamin K group consisted of 20 patients were given oral vitamin K at 10 mg after each session of dialysis for a duration of one year. No-Vitamin K group included 20 patients didn’t receive vitamin K. All patients were subjected to the following: Matrix Gla protein (MGP), in addition to, plain digital abdominal x-ray and doppler ultrasound. Results: After one-year of vitamin K supplementation, a significant increase in MGP levels in Vitamin K group (75.7±26 ng/mL) were noticed. There were no significant changes in CIMT and AACS in Vitamin K group after vitamin K supplementation in compared to their baseline levels, while the CIMT and AACS were significantly increased in No-Vitamin K group in compared to their baseline levels. Conclusion: Vitamin K supplementation could not stop vascular calcifications but significantly attenuate their progression.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
