Hemorheology and fistula function in home hemodialysis patients following erythropoietin treatment: a prospective placebo-controlled study.
The beneficial effect of correcting anemia in end stage renal failure using recombinant human erythropoietin (rHuEPO) is sometimes complicated by thrombosis of the arteriovenous fistula. This placebo-controlled study investigated the relationship between hemorheological changes caused by rHuEPO and alterations in fistula function and heparin requirements in home hemodialysis patients. Erythropoietin induced a rise in high shear rate blood viscosity, a determinant of blood flow in large vessels. Doppler assessment of brachial artery blood flows, tests of fistula function and heparin requirements were similar in the two patient groups. These findings indicate that rHuEPO treatment of renal anemia resulted in the expected rise in red blood cell mass and blood viscosity although these changes did not cause problems with arteriovenous access or alter fistula function in the short term.
