Overview
Diamond Black-fan Anemia must be differentiated from other diseases that cause Anemia and bone marrow failure such as Aplastic anemia, Fanconi anemia, Transient Erythroblastopenia of Childhood, Shwachman-Diamond syndrome, Pearson syndrome, Dyskeratosis congenita, Cartilage-hair hypoplasia, Congenital amegakaryocytic thrombocytopenia, Infections: Parvovirus B19, HIV, Viral hepatitis, Drugs, and toxins (eg. antileptic drugs, azathioprine), Immune-mediated disorders( eg Thymoma, Myasthenia Gravis, SLE)
Dimond-Blackfan anemia differential diagnosis
- Aplastic anemia
- Fanconi anemia is a bone marrow failure syndrome, present with pancytopenia, and physical abnormalities usually present within the first decade of life.
- Transient Erythroblastopenia of Childhood is anacquired anemia usually (over 80%) presents at one year of age, while DBA usually (90%) presents before one year of age.[1]
- Shwachman-Diamond syndrome (SDS) is a clinical syndrome characterized by exocrine pancreatic dysfunction with malabsorption, single or multi-lineage cytopenia, growth failure, bone abnormality, and susceptibility to myelodysplastic syndrome, and AML[2][3]
- Pearson syndrome is an inherited mDNA mutation characterized by sideroblastic anemia of childhood, exocrine pancreatic failure, liver failure, renal tubular defects, and pancytopenia. Death generally occurs in infancy due to liver failure.
- Dyskeratosis congenita (DC) is an inheretied disorder with the classic triad of lacy reticular pigmentation of the upper chest and/or neck, dysplastic nails, and oral leukoplakia. These patients have an increased risk of MDS, BMF, or AML. [2]
- Cartilage-hair hypoplasia (CHH)It is an autosomal recessive inherited disorder characterized by anemia, macrocytosis, defective T cell-mediated immune response, short tubular bone, and fine sparse blond hair.
- Congenital amegakaryocytic thrombocytopenia (CAMT) usually presents at birth or in infancy with severe thrombocytopenia, petechiae, and/or intracranial or intestinal mucosal bleeding. In childhood, these patients may develop pancytopenia, MDS, or leukemia.
- Infections: Parvovirus B19, HIV, Viral hepatitis
- Drugs and toxins (eg. antileptic drugs, azathioprine)[4]
- Immune-mediated disorders( eg Thymoma, Myasthenia Gravis, SLE)
