Abstract

BackgroundPeripheral artery disease PAD represents atherosclerotic disease and is a risk factor for death in peritoneal dialysis PD patients, who tend to show an atherogenic lipid profile. In this study, we investigated the relationship between lipid profile and ankle-brachial index ABI as an index of atherosclerosis in PD patients with controlled serum low-density lipoprotein LDL cholesterol level.

MethodsThirty-five PD patients, whose serum LDL cholesterol level was controlled at less than 120mg-dl, were enrolled in this cross-sectional study in Japan. The proportions of cholesterol level to total cholesterol level cholesterol proportion in 20 lipoprotein fractions and the mean size of lipoprotein particles were measured using an improved method, namely, high-performance gel permeation chromatography. Multivariate linear regression analysis was adjusted for diabetes mellitus and cardiovascular and-or cerebrovascular diseases.

ResultsThe mean standard deviation age was 61.6 10.5 years; PD vintage, 38.5 28.1 months; ABI, 1.07 0.22. A low ABI 0.9 or lower was observed in 7 patients low-ABI group. The low-ABI group showed significantly higher cholesterol proportions in the chylomicron fraction and large very-low-density lipoproteins VLDLs Fractions 3–5 than the high-ABI group ABI>0.9. Adjusted multivariate linear regression analysis showed that ABI was negatively associated with serum VLDL cholesterol level parameter estimate=-0.00566, p=0.0074; the cholesterol proportions in large VLDLs Fraction 4, parameter estimate=-3.82, p=0.038; Fraction 5, parameter estimate=-3.62, p=0.0039 and medium VLDL Fraction 6, parameter estimate=-3.25, p=0.014; and the size of VLDL particles parameter estimate=-0.0352, p=0.032.

ConclusionsThis study showed that the characteristics of VLDL particles were associated with ABI among PD patients. Lowering serum VLDL level may be an effective therapy against atherosclerosis in PD patients after the control of serum LDL cholesterol level.
