Popis: Purpose In patients on long-term hemodialysis, high lipoprotein(a) [Lp(a)] levels are difficult to lower with medications, although they remain a risk factor for cardiovascular disease. We investigated whether ultrapure dialysate (UPD) could lower Lp(a). Methods: We randomly assigned patients stabilized on long-term dialysis to either a low-flux synthetic polysulphone membrane (the UPD group; n=14) or to a conventional dialysate (the CD group; n=13). Blood samples were collected 1 week before dialysis and 1 week, 1 month, 6 months and 12 months after dialysis; Lp(a) was measured by the immunotur-bidimetry method. Hemoglobin, interleukin-6, hypersensitive C-reactive protein, β2 microglobulin and albumin were also measured. The erythropoietin dosage, Kt/V, and normalized protein catabolic rate were recorded monthly. Results At 12 months, mean (SD) serum levels of Lp(a) in the CD patients increased from 143.46 (125.11) to 283.89 (145.81) mg/L (pConclusions Ultrapure dialysate can prevent the rise of Lp(a), potentially decreasing the risk of cardiovascular disease in hemodialysis patients.
