Abnormal iron incorporatin, survival protoporphyrin content and fluorescence of one red cell population in preleukemic sideroblastic anemia.
The dimorphic blood picture in sideroblastic anemia suggests the coexistence of at least two types of erythrocyte, the populations with the smaller RBCs being responsible for the crucial abnormality, namely the impairment of iron incorporation into protoporphyrin. In a patient with sideroblastic anemia who subsequently developed acute myelocytic leukemia, we found a light and a heavy cell popul...

متن کاملNatural history of idiopathic refractory sideroblastic anemia.
We analyzed the natural history of idiopathic refractory sideroblastic anemia (IRSA) in 37 patients studied between 1969 and 1986. Although erythroid abnormalities were prominent in all, 12 patients also showed involvement of the granulocytic and/or megakaryocytic cell lines, and nonrandom chromosomal aberrations were observed in five of 23 patients studied for such defects. Measurements of ery...
متن کاملSideroblastic anemia.
When first defined 50 years ago, sideroblastic anemia (SA) was already recognized to occur in heterogeneous settings, including as familial or acquired disease. The spectrum of SA has since become considerably expanded with respect to distinct clinical phenotypes as well as discrete causes. The singular feature that typifies all forms of SA and is required for initial diagnosis is the presence ...
متن کاملAssociation of HLA-linked hemochromatosis with idiopathic refractory sideroblastic anemia.
Five of seven patients with idiopathic refractory sideroblastic anemia carried an HLA-A3 alloantigen (relative risk, 7.3; P = 0.02). The significance of this association was strengthened by study of two pedigrees. An abnormality in iron metabolism was found in two siblings who had an HLA-A3,B14 haplotype in common with the first proband. A second proband with idiopathic refractory sideroblastic...
