How do you treat Blackfan Diamond?

Bone marrow transplant is the only treatment that is curative for Diamond-Blackfan anemia. Compatible means that the donor has the same types of proteins, called human leukocyte antigens (HLA), on the surface of their cells as the person with Diamond-Blackfan anemia who will be receiving the transplant.

What is the difference between Fanconi and Diamond Blackfan anemia?

This is in contrast to Shwachman–Bodian–Diamond syndrome, in which the bone marrow defect results primarily in neutropenia, and Fanconi anemia, where all cell lines are affected resulting in pancytopenia….

Why is Diamond Blackfan Anemia Macrocytic?

Diamond Blackfan anemia (DBA) is a dominantly inherited macrocytic anemia, often associated with congenital anomalies. Twenty-five percent of cases result from haploinsufficiency of ribosomal protein S19 (RPS19), and ~30% result from haploinsufficiencies of 10 other ribosomal proteins (1).

When is Diamond-Blackfan anemia diagnosed?

Diamond-Blackfan anemia, also known as acquired pure red cell aplasia, is usually diagnosed when a child is less than a year old. It’s caused by changes, or mutations, in their genes, which are the building blocks of DNA. Sometimes the genetic mutation is passed down from one parent to a child.

It’s often diagnosed during the first year of life with blood and bone marrow tests. DBA is treated with corticosteroids and blood transfusions. Stem cell transplants offer a cure for DBA.

Is Diamond Blackfan Anemia curable?

For some children, Diamond-Blackfan anemia can be cured by having an infusion of blood-forming stem cells from a healthy donor. This is called a stem cell transplant or bone marrow transplant or hematopoietic (him-at-oh-poy-EH-tik) cell transplant. It helps your child’s bone marrow make normal blood cells.
