Reticulocyte parameters: markers of early response to oral treatment in children with severe iron-deficiency anemia.

The aim of the present study was to determine the effects of exclusive oral iron supplementation (iron sulphate 2 mg/kg/die) in asymptomatic children with severe iron-deficiency anemia [median hemoglobin (Hb) level before treatment 6.3 g/dL; range 4.5 to 7 g/dL] and to investigate the accuracy of Hb, reticulocyte hemoglobin content (CHr), and absolute reticulocyte count (ARC) as markers for monitoring early response to treatment.
