In a double-blind, placebo-controlled trial of rHu-EPO (recombinant human erythropoietin) comprizing 19 haemodialysis patients (rHu-EPO: n = 9, placebo: n = 10) the patients' opinion about the influence of the treatment on the quality of life was investigated. At the commencement of the trial and after eight weeks, a score was registered by means of a structured interview with a range of 0-10 concerning the complaints most frequently expressed by haemodialysis patients. Erythropoietin was effective in the treatment of renal anaemia. In the therapeutic group, the mean haematocrit value increased from 0.206 to 0.338 (p less than 0.0005), while no change in the haematocrit value was observed in the placebo group. In the therapeutic group, significant decreases were found in the interview scores for fatigue, vertigo (p less than 0.001), dyspnoea (p less than 0.0025), muscular weakness (p less than 0.01) and palpitations (p less than 0.05). No significant differences were found in the placebo group. The treatment had no serious side-effects. On the basis of this material, it is concluded that erythropoietin treatment of haemodialysis patients is effective and that a marked improvement in the quality of life can be observed already after treatment for eight weeks.

A 62-year-old man with a history of coronary insufficiency complained at his scheduled visit to the outpatient clinic of symptoms suggestive of gastritis. His blood hemoglobin concentration, however, was markedly increased. Results of a hematological work-up suggested an erythropoietin-producing tumor. Signs of increased intracranial pressure then led to the finding of a cerebellar tumor, which could explain his vertigo and abdominal symptoms. This cystic capillary hemangioblastoma probably was responsible for the erythropoietin production and also seemed to produce basic fibroblast growth factor. The clinical evaluation of polycythemia as well as erythropoietin biochemistry and clinical application are reviewed.

Cancer-related anemia often develops from the infiltration of marrow by malignant cells, impaired hemoglobin (Hb) production related to chemotherapy or radiation therapy, iron deficiency, or low endogenous erythropoietin levels. Patients with cancer-related anemia may experience cognitive dysfunction including decreased mental alertness, poor concentration, and memory problems. Anemia-mediated cerebral hypoxia may cause symptoms such as headache, vertigo, tinnitus, and dizziness. These symptoms often are exacerbated in the elderly patient with cancer and related to underlying low Hb concentrations. Restoring Hb levels via the administration of iron supplements, blood transfusions, or, more recently, erythropoiesis-stimulating therapy (epoetin alfa) results in significant improvement of cognitive function. The use of epoetin alfa as a treatment option for patients with chemotherapy-associated anemia and an Hb concentration less than 10 g/dL has been recommended by the American Society of Clinical Oncology and the American Society of Hematology. Erythropoiesis-stimulating therapies are a promising treatment option for cancer-related anemia that may improve cognitive function and quality of life for patients with cancer.
