Abstract
Diamond Blackfan anemia is a rare congenital hypoplastic anemia that usually presents early in infancy. Congenital anomalies, in particular of the head and upper limbs, are present in about 25% of reported patients. The disease is characterized by a moderate to severe macrocytic anemia, occasional neutropenia or thrombocytosis, a normocellular bone marrow with erythroid hypoplasia, and an increased risk of developing leukemia. Recent genetic studies have led to the identification of mutations in the ribosomal protein RPS19 in approximately 25% of sporadic and familial cases, a second gene on chromosome 8p, and evidence for an additional locus (or loci). The pathogenesis is unknown. The majority of patients respond to prednisone, and often erythropoiesis can be maintained with low doses of the drug. Both remissions and increased resistance to steroid treatment can occur. Patients who do not respond to treatment are usually transfusion dependent, although responses to high dose steroid, androgen, and interleukin-3 have been observed. Bone marrow transplantation can be curative.Keywords
