Subcutaneous recombinant erythropoietin in preterminal renal insufficiency.

Recombinant human erythropoietin was given to eight children and adolescents with stable chronic renal failure in the predialysis state. The hormone was administered subcutaneously, twice weekly for 12 weeks, at a starting dose of 50 U/kg per week. The dosage was adapted every 4th week. Target haemoglobin was 10.5-11.5 g/dl, and the target haematocrit 32%-35%. Baseline haemoglobin levels of 8.20 +/- 0.93 g/dl increased to 9.17 +/- 1.10, 10.38 +/- 1.18 and 11.19 +/- 0.84 g/dl (mean +/- SD) after 4, 8 and 12 weeks respectively. Serum ferritin levels decreased progressively despite iron supplementation. No side-effects were observed: creatinine clearances remained stable, blood pressure did not increase and none of the patients displayed either convulsions or thrombotic features. The study shows that subcutaneous recombinant human erythropoietin is both effective and safe in anaemic children and adolescents with chronic renal insufficiency.
