Abstract

To evaluate objectively the effects of recombinant human erythropoietin (rHuEPO) administration on nutritional status in stable dialyzed patients, we used urea kinetic modeling (UKM) analysis and dietary protein intake evaluation by dietary assessment. Fifteen patients (9 females, 6 males; mean age 46.9 +/- 15.6 years) dialyzed for 9.4 +/- 6.3 years were studied longitudinally for 18 months, consisting of a control period (6 months) and an rHuEPO treatment period (12 months). Treatment modalities based on 3 weekly sessions were hemodialysis in 12 patients (6 cuprophane, 3 cellulose acetate and 3 highly permeable membranes), hemodiafiltration in 2 patients and postdilutional hemofiltration in 1 patient. Bicarbonate buffered dialysate was used in 9 patients and acetate in 6 patients. Urea kinetic modeling using a single-pool model was performed monthly over 1-3 cycles. rHuEPO was administered intravenously at the end of dialysis according to a two-phase protocol: (1) correction of anemia by stepwise increment of rHuEPO dose, and (2) maintenance dose to keep hemoglobin at 10-11 g/dl. rHuEPO administration corrected anemia in all patients, improving their general clinical condition. Dialysis efficacy was significantly reduced (15%)...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
