Brief Summary:
Vascular calcification is the leading cause of death in patients with end stage renal disease ESRD in hemodialysis The protein matrix Gla vitamin K dependent MGP is a potent inhibitor of the vascular calcification Objective To evaluate the effect of vitamin K2 on vascular calcification in patients on hemodialysis Materials and Methods A prospective randomized double-blind study will be performed The study subjects will be divided into a control 1000 µl of saline or treated group 1000 µl containing 2000 µg of Vitamin K2 Vitamin K2 will be administered three times a week intravenously at the end of each dialysis session Blood samples for biochemical determinations and vascular calcification will be assessed before and after 6 months of treatment through carotid Doppler ultrasound
Detailed Description:
This study is designed according to the ethical reference framework for biomedical research of the Declaration of Helsinki Its design is prospective randomized double blind Study subjects will be assigned either Arm 1 or control vial with 1000 μL of saline or Arm 2 or treated group vial with 1000 μL containing 2000 μg of Vitamin K2 The trial protocol was approved by the ethics committee of the Catholic University of Salta and written informed consent will be made available to all patients who agree to participate and meet the inclusion criteria Vascular calcification will be evaluated at the beginning of the study to determine the presence of vascular calcification and at the end of the study to assess changes if any The carotid artery examination will be performed with a GE VIVID 5 GE Healthcare Little Chalfont Buckinghamshire UK with a 75 MHz linear probe The protocol used to obtain images is consistent with the recommendations of the American Society of Echocardiography Longitudinal images will be obtained by means of B-mode ultrasound the maximum and the global median intima thickness EIM value of the common carotid artery and the presence of carotid plaques defined as isolated and focal areas of the abnormal intima that protrude into the lumen more than 15 mm or at least 50 of the surrounding total mean intimate value The EIM represents the thickness of the intima plus the component of the mean of the vessel wall with an automated computerized system of the equipment on the distal wall of both common carotid arteries 1 cm below the carotid bulb along a 10 mm long straight arterial segment Patients may be stratified into 3 groups according to the EIM value EIM patients with 05 mm are considered disease-free patients with IMD between 06-1 mm will be considered to be non-significantly affected by the disease patients with IMD 1 mm will be grouped as affected by significant disease Table 1 Therefore carotid atherosclerosis is considered in the presence of plaques or an EIM 1 mm 253 Table 1 Thickness of the intima plus the component of the mean in the wall of a vessel associated or not with the presence of vascular calcification
EIM VALUE Presence or not of vascular calcification 05 mm Patients without vascular calcification 06-1 mm Patients non-significantly affected by the disease 1 mm Patients significantly affected by the disease
EIM VALUE Presence or not of vascular calcification 05 mm Patients without vascular calcification 06-1 mm Patients non-significantly affected by the disease 1 mm Patients significantly affected by the disease
