Improved lipid profiles in patients undergoing high-flux hemodialysis.
Hyperlipidemia is one of many atherogenic risk factors encountered by patients undergoing chronic hemodialysis (HD). We have studied lipid profiles in these patients and have found less hypertriglyceridemia in those undergoing high-flux HD than those receiving traditional HD. Mean +/- SEM triglyceride level was 1.62 +/- 0.15 mmol/L (143.3 +/- 13.6 mg/dL) in high-flux dialysis patients, 2.39 +/- 0.27 mmol/L (211.6 +/- 24.1 mg/dL) in conventional dialysis patients, and 1.55 +/- 0.13 mmol/L (137.1 +/- 11.5 mg/dL) in normal age- and sex-matched controls. In addition, we found that in patients undergoing high-flux HD, females had higher high-density lipoprotein2 (HDL2) levels (0.62 +/- 0.03 mmol/L [23.8 +/- 1.3 mg/dL]) than males (0.33 +/- 0.04 mmol/L [12.9 +/- 1.7 mg/dL]) (P < 0.01). The mechanism(s) responsible for divergent lipid profiles in subsets of HD patients deserves further investigation. Whether reductions of hypertriglyceridemia and/or increases of HDL2 will diminish the incidence of cardiovascular disease in dialysis patients is unknown.
