The effectiveness of recombinant human erythropoietin (r-HuEpo)

The impact of chronic administration of the luteinizing hormone-releasing hormone agonist leuprolide depot on cardiovascular risk factors was investigated in a controlled double-blind study comprising 50 evaluable patients with benign prostatic hyperplasia. In the 26 patients receiving leuprolide the mean total cholesterol level increased by 10.6%, high density lipoprotein cholesterol by 8.2% and triglycerides by 26.9% (p = 0.003, 0.052 and 0.050, respectively). Low density lipoprotein cholesterol levels were unchanged. Apolipoprotein A1 increased by 13.2% (p = 0.001), while apolipoprotein B, fibrinogen, thrombocytes and plasminogen activator inhibitor were unchanged. Hemoglobin decreased by 1.2 gm./100 ml. without a concomitant decrease in serum erythropoietin concentration. These changes act in different directions with regard to cardiovascular risk and the overall effect is difficult to assess.

Commercial cow's milk protein added to human milk was as good as human milk protein supplementation in supporting growth and erythropoiesis. Fifty IU/kg r-HuEpo thrice weekly during AOP stimulated erythropoiesis significantly, but less so than 100 IU/kg. Even when using high oral doses of iron to preterms receiving r-HuEpo, our data suggested a certain degree of iron deficient erythropoiesis.
