[Findings in relation to serum and urinary iron in heterozygotic beta-thalassemia].
Iron status (expressed as serum ferritin and iron levels) has been compared in normal and in heterozygous beta-thalassemic subjects. A higher serum ferritin concentration has been found in beta-thalassemic males, showing, therefore, a shift towards super-normal values of the balance between tissue iron and serum ferritin levels. In beta-thalassemic subjects the serum ferritin levels have been found in the normal range and this seems to be correlated with an adequate and ready iron supply by protein transferrin to hyperplastic bone marrow. The higher urinary iron values in normal male subjects can be explained in this way: a large iron supply from the transferrin to the thalassemic erythroid cells limits the contribution from this protein to the urinary iron.
