Racial differences in plasma high-density lipoproteins in patients receiving hemodialysis. A possible mechanism for accelerated atherosclerosis in white men.

Among 346 nondiabetic patients receiving long-term hemodialysis, cardiovascular mortality was higher in white than in black men (P less than 0.02) but was similar between black and white women, despite the higher incidence of nephrosclerosis in black men and women (59 and 58 per cent vs. 8 and 10 per cent, respectively; P less than 0.0001). There were significant racial differences in plasma lipid and apoprotein levels in a subset of 100 of these patients. The white men had higher levels of plasma triglyceride and lower levels of high-density-lipoprotein (HDL) cholesterol, apoprotein A-I, and apoprotein A-II than black men; concentrations of HDL, apoprotein A-I, and apoprotein A-II were also lower in white than in black women. The distribution of the HDL subfractions HDL2, HDL3, and HDL3D, as determined by zonal ultracentrifugation, was normal in black and abnormal in white men receiving hemodialysis. HDL2 concentrations were higher in black than in white men by both zonal analysis (P less than 0.05) and polyanionic precipitation of the HDL subfractions (P less than 0.01). The distributions and concentrations of HDL2 and HDL3L were similar in black and white women. Thus, there are marked racial differences in HDL in male patients receiving hemodialysis. The abnormalities in HDL and the hypertriglyceridemia in the white men may explain their high rate of cardiovascular mortality.[1]
