Evaluation of the supertransfusion regimen in homozygous beta-thalassaemia children.
The maintenance of physiological levels of haemoglobin is beneficial in the management of patients with thalassaemia major since it leads to better tissue oxygenation, reduction of blood volume, and reduced intestinal absorption of iron. We have studied 11 patients with thalassaemia major while treating them for 4-12 months with a standard transfusion regimen (mean pre-transfusion Hb 10.2 g/dl) and then for a second period of 7-18 months with a supertransfusion regimen (mean pre-transfusion Hb 12.3 g/dl). Blood consumption was 16.71 +/- 2.0 ml/kg/month in the first period; it rose to 20.30 +/- 3.5 ml/kg/month in the first 5 months of the second period, and then returned to the values of the first period (16.53 +/0 2.0 ml/kg/month). There were no significant differences in blood consumption between the two transfusion regimens, after the 5-month equilibration period.
