Red cell ferritin and iron overload in heterozygous beta-thalassemia.

Abstract:

:Red cell ferritin was evaluated in 101 individuals with heterozygous beta-thalassemia to determine its clinical utility as an index for iron deficiency or overload in these subjects. The mean red cell ferritin for the total population was elevated threefold and showed a significant correlation with transferrin saturation, plasma ferritin, and HbA2 levels. Five of six subjects with reduced red cell ferritin had associated iron deficiency; a further five had iron deficiency and normal red cell ferritin. Normal red cell ferritin occurred in 51 subjects, and 44 had increased values. In the elevated red cell ferritin group, 21 individuals had associated normal plasma ferritin, and 23 had increased plasma ferritin. Only in the latter group was red cell ferritin significantly correlated with transferrin saturation and plasma ferritin. Ten individuals had a red cell ferritin greater than or equal to 150 attogram/cell, and liver biopsy performed in four showed grades II to IV iron overload. A clinical feature of subjects with both increased red cell and plasma ferritin levels was a high incidence of inappropriate iron administration. These findings suggest that red cell ferritin, particularly when combined with plasma ferritin, is a useful parameter for determining potential iron overload in individuals with heterozygous beta-thalassemia.
