Overview
Pure red cell aplasia (PRCA) is a rare hematologic disorder characterized by selective failure of red blood cell production by the bone marrow, often associated with immune-mediated mechanisms. 1Diagnosis
Bone marrow biopsy showing absent or markedly decreased erythroid precursors 1
Elevated reticulocyte count with low hemoglobin levels 1
Exclusion of other causes of anemia through comprehensive blood work 1Management
Blood transfusions for symptomatic relief and to manage anemia 1
Corticosteroids as a first-line immunosuppressive treatment 1
Consideration of other immunosuppressive agents if corticosteroids are ineffective 1Special Populations
Pregnancy: PRCA can occur at any gestational age, often resolves postpartum, but has a high risk of relapse in subsequent pregnancies 1
Relapse risk: Women with a history of pregnancy-induced PRCA have a significant chance of recurrence with subsequent pregnancies or with progestin exposure 1Key Recommendations
Monitor and manage PRCA during pregnancy with blood transfusions as primary support, with corticosteroids as first-line therapy 1 (Evidence: Moderate)
Evaluate for potential relapse in subsequent pregnancies or with progestin use in women with a history of pregnancy-induced PRCA 1 (Evidence: Moderate)
Consider alternative immunosuppressive treatments if corticosteroids fail to resolve PRCA 1 (Evidence: Weak)References
