GUTIERREZ DIAZ, Adys I. et al. Type 1 congenital dyserytropoieitc anemia: A case presentation. Rev Cubana Hematol Inmunol Hemoter [online]. 2010, vol.26, n.2, pp. 62-70. ISSN 1561-2996.

The congenital dyserytropoietic anemias (CDT) include a series of hematopoiesis hereditary disorders characterized by a refractory anemia of variable severity. There are three fundamental types: 1, 2 and 3. The gen accounted for CDT-1(CDAN1) is located in 15q15 chromosome, although recent studies demonstrate the heterogeneity of this disease. This is the case of a female patient aged 3 diagnosed with CDT-1who at three months old had a severe anemia, indirect hyperbilirubinemia, slight reticulocytosis, high transfusion requirements and stature disorders due to its low height. Ham’s was negative and in peripheral blood there was macrocytosis predominance. Bin bone marrow examination it was possible to observe dyserytropoiesis with erythroid hyperplasia, megaloblast hematopoiesis, intracytoplasm precipitates, irregular nuclei, karyorresis, binuclearization and internuclear bridges. There wasn’t response to treatment with the recombinant type α interferon. Patient is under chelation treatment with deferoxamine and it was proposed the possibility of no-related allogenic of hematopoietic parent cell.
