Abstract

Plasma levels of alpha-tocopherol (vitamin E) in chronic renal insufficiency (CRI) patients may be decreased, normal or elevated. However, an abnormal distribution of vitamin E in each lipoprotein has been reported. In comparison to control subject low-density lipoprotein (LDL), patient LDL contained less vitamin E. On the contrary, malondialdehyde (MDA) in patient LDL was enhanced. According to the evaluation of the susceptibility of LDL to in vitro oxidation and the rate of lipid peroxidation by fluorescence development during copper exposure, the susceptibility of patient LDL was enhanced, suggesting a possible relationship between excessive LDL peroxidation and accelerated atherosclerosis. In a clinical small uncontrolled trial, the increments of an aortic calcification index estimated by CT scan in patients treated with vitamin E were suppressed compared to those treated without vitamin E, suggesting that vitamin E might prevent the progress of atherosclerosis in CRI patients.
