Overview
Congenital hypoplastic anemia, including Blackfan-Diamond syndrome (BDS), is a rare hematologic disorder characterized by ineffective erythropoiesis leading to severe anemia, often presenting in infancy with growth retardation and other congenital anomalies 1.Diagnosis
Prenatal suspicion based on family history of BDS
Detailed fetal ultrasonography to assess for hydrops fetalis and structural anomalies
Fetal echocardiography to evaluate cardiac function and detect signs of anemia
Cordocentesis for confirming anemia and assessing fetal blood parameters 1Management
First-line: Early initiation of corticosteroid therapy (dose specifics not provided in abstract)
Adjunctive: Red blood cell transfusions as needed for severe anemia
Special considerations: In utero transfusions if anemia is severe and other treatments are insufficient
Planned intervention: Early delivery if fetal condition warrants 1Special Populations
Pregnancy: Prenatal counseling for parents with BDS, serial monitoring via ultrasound and echocardiography, consideration of in utero transfusions, and planned early delivery for affected fetuses 1Key Recommendations
Provide prepregnancy genetic counseling for individuals with BDS 1 (Evidence: Expert opinion)
Implement detailed and serial fetal ultrasonography and echocardiography for at-risk pregnancies 1 (Evidence: Expert opinion)
Consider cordocentesis and in utero transfusions if signs of fetal anemia are present 1 (Evidence: Expert opinion)
Plan for early delivery if fetal condition necessitates intervention 1 (Evidence: Expert opinion)References
