Overview
DBA typically present with common symptoms of anemia, including pale skin, sleepiness, irritability, tachycardia. Common complications of DBA include physical abnormalities, Cancer predisposition, eye problems such as cataracts, glaucoma, or strabismus, kidney abnormalities, hypospadias, and secondary complications due to standard therapies( Corticosteroids treatment, Red cell transfusion, Bone marrow transplantation). Prognosis is relatively good, overall actuarial survival is 75% at age 40 years
Diamond-Blackfan anemia natural history, complications and prognosis
Natural history
- DBA typically presents in infancy, most commonly with pallor and lethargy, median age at presentation is 8 weeks. Hydrops fetalis in some cases have been seen.[1][2]The severity of Diamond-Blackfan anemia may vary, even within the same family.
Complications
- Common complications of Diamond-Blackfan anemia include:
- Physical abnormalities
- higher-than-average chance of developing myelodysplastic syndrome (MDS), acute myeloid leukemia (AML), bone cancer (osteosarcoma), colon cancer[3]
- Eye problems such as cataracts, glaucoma, or strabismus
- kidney abnormalities
- hypospadias
- Secondary complications due to standard therapies( Corticosteroids treatment, Red cell transfusion, Bone marrow transplantation):
- Oragans involvement due to Transfusion iron overload
- Cirrhosis or fibrosis of the liver
- Cardiac arrythmias
- Diabetes
- Reproductive organ failure
- Growth stunting
- Endocrine failure affecting the thyroid and adrenal
- Side effects of corticosteroids
- Osteoporosis
- Weight gain
- Cushingoid appearance
- Hypertension
- Diabetes mellitus
- Growth retardation
- Pathologic bone fractures
- Gastric ulcers
- Cataracts
- Glaucoma
- Increased susceptibility to infection
- Stem cell transplantation
- Oragans involvement due to Transfusion iron overload
Prognosis
Prognosis is relatively good, overall actuarial survival is 75% at age 40 years, but complications related to treatment may alter the quality of life of the affected individuals. Severe complications as a result of treatment or the development of cancer may reduce life expectancy. [4]
- Ultimately, 40% of case subjects remain dependent upon corticosteroids which increase the risk of heart disease, osteoporosis, and severe infections. [5]
- Another 40% become dependent upon red cell transfusions which require regular chelation to prevent iron overload and increases the risk of alloimmunization and transfusion reactions, and can cause severe co-morbidities.[6]
