A major cause of the morbidity and mortality of patients with end-stage renal disease (ESRD) is related to disorders of large blood vessels, especially coronary heart disease. Atherosclerosis, the most common form of this disease, is known to result from abnormalities in plasma lipoproteins, as well as from factors that damage the vessel wall. Two well-known risk factors for coronary heart disease are elevated plasma concentrations of LDL and reduced concentrations of HDL. This latter disorder is often accompanied by elevated triglycerides. Low HDL and elevated triglycerides are commonly associated with ESRD. Dialysis with high flux membranes differs from conventional dialysis in a number of ways. These include better biocompatibility and increased flux of larger molecules. Although several previous studies had suggested that dialysis with high flux membranes improves plasma lipoprotein profiles, a definitive cross-over designed study to assess the roles of high flux versus biocompatibility in altering lipoprotein profiles had not been done. Preliminary data from such a study are presented. These data confirm the beneficial effects of high flux membranes to reduce plasma triglycerides and suggest that this effect is primarily due to the high flux, and not the biocompatible, feature of the membranes.
