Fifteen long-term hemodialysis patients suffering from stable anemia received recombinant human erytheropoietin (r-huEPO). The hormone was given intravenously at the end of each dialysis session starting with a dose of 24 IU/kg. This dose was doubled when hemoglobin levels did not rise within 2 weeks. The number of reticulocytes started to increase after 14 days of treatment. The hematocrit rose from baseline values of 23.7 ± 1.2% to 32.4 ± 1.3% after 24 weeks of treatment. In parallel, hemoglobin values increased from 7.3 ± 0.3 g/100 ml to 10.1 ± 0.4 g/100 ml. As for side effects, 3 patients developed hypertension and 2 patients suffered from occlusions of their arterio-venous fistulas. There was no evidence of major organ dysfunctions, toxic effects, allergic reactions, or antibody formation. These data show that rHuEPO is able to correct the anemia of patients undergoing hemodialysis treatment.

Before And After

Twenty -two continuous ambulatory peritoneal dialysis (CAPD) patients, mean age 48 years, at 3 U.K. renal units were assessed with the Nottingham Health Profile (N HP) before and after treatment with recombinant human erythropoietin (r-HuEPO). Mean (SD) hemoglobin (Hb) at baseline was 7.5 (1.0) gIn/dl and 10.8 (1.5) gIn/dl at retest. There were significant improvements in energy (p<0.0001), social life (p<0.005), relationships at home (p<0.05) and leisure pursuits (p<0.05). Twelve patients, mean age 51 years, who had already completed more than 9 months on r-HuEPO treatment were reassessed to determine the changes sustained. Mean (SD) Hb at second retest was 12.8 (1.3) gm/dl. Improvement in energy continued to be significant, and emotional wellbeing showed further improvement. Problems with household tasks, which had not shown significant improvement at Test B, were now considerably reduced (p=0.016). The study showed far-reaching benefits similar to those reported in hemodialysis patients, in a population with a higher mean age and higher potential coexisting illness or disability than most reported hemodialysis studies.

Abstract The thrombopoietic status of patients with uremia remains unclear. This issue was addressed with particular reference to marrow megakaryocytopoiesis and endogenous thrombopoietin (TPO) levels. A study was conducted in 114 patients on hemodialysis, 43 patients on continuous ambulatory peritoneal dialysis, and 48 age-matched controls. Reticulated platelets, a marker of marrow megakaryocytopoiesis, were measured by flow cytometry. Serum TPO levels, platelet-associated IgG (PAIgG) levels, and hepatitis C virus (HCV) antibody titers were also measured by enzyme-linked immunosorbent assay. Circulating and reticulated platelet counts were significantly lower in the patients on dialysis than in the controls. Thrombocytopenia (less than 150 × 109/L) was most frequent in the HCV-positive hemodialysis patients, who had a higher incidences and higher PAIgG titers. The following results were obtained in the HCV-negative dialysis patients: (1) platelet counts chronologically decreased with years on hemodialysis; (2) platelet counts were associated with the reticulated platelet counts; (3) serum TPO levels were significantly elevated in the dialysis patients, responding to the decrease of reticulated platelets; (4) hematocrits had a positive correlation with serum TPO levels, and serum TPO levels were significantly higher in the patients on hemodialysis who did not require recombinant human erythropoietin therapy than in the other patients. In conclusion, thrombocytopenia is a frequent finding in patients on dialysis. The failure of megakaryocyte production could be the principal cause of the platelet reduction, and the peripheral destruction and sequestration of platelets may be concomitantly involved. Elevation of serum TPO may in part serve as an aid to erythropoiesis in dialysis patients.
