Utilization of iron dextran in recurrent iron deficiency anaemia.
Previously published studies have documented a reduction in the rate at which iron stores laid down by iron dextran therapy can be utilized for haemoglobin synthesis after the acute demands of haemorrhage and phlebotomy. In order to determine if a defect in the mobilization of these stores exists in the face of a chronic stimulus to red cell production, 93 patients who had previously received a total dose infusion of iron dextran were examined for a recurrence of iron deficiency anaemia, and in those in whom anaemia had recurred, iron stores were assessed by marrow aspiration. Twenty of the 93 patients were found to have recurrent iron deficiency anaemia, and marrow aspiration in all failed to demonstrate stainable iron stores. Although the rate at which iron dextran can be mobilized from storage sites is reduced, the present study demonstrates that ultimately these stores are fully utilizable.
