Introduction: After several years of erythropoietin (EPO) use in the prophylaxis of anaemia of prematurity, it also began to be administered to treat post-haemolytic disease anaemia of the newborn in order to avoid blood transfusions.
Objective: To show the results obtained with EPO treatment in post-haemolytic disease anemia of the newborn.
Patients and methods: Observational study in 13 newborns with late anaemia due to an hemolytic disease caused by Rh isoimmunization (9 cases), AB0 isoimmunization (2 cases), glucose-6-P-dehydrogenase deficiency (1 case) or idiopathic (1 case). The newborns began EPO treatment when they reached the haematocrit level for a blood transfusion.
Results: EPO treatment was started at 26±7 days of life (15-46), with a haematocrit value of 21.7±3% (18-27) and a reticulocyte count of 3.8±2.2%. Blood transfusion was not necessary in 11 newborns (haematocrit of 30.7±4.4% and reticulocytes of 5.9±1.4%), and only 2 newborns were admitted for a blood transfusion (haematocrit 18±4.4% and reticulocytes 0.6%). Significant increases in haemoglobin and reticulocyte figures were seen after EPO treatment.
Conclusions: EPO administration proved useful to avoid blood transfusion in 84% of treated newborns. No adverse events were detected which could be attributed to this treatment,.
