Pure Red Cell Aplasia (PRCA)

 

 

Overview

The production of red blood cells declines due to bone marrow damage, which leads to anemia. This bone marrow disease can be acquired or inherited (present at birth). The two acquired forms are known as primary and secondary.  The primary form involves autoantibodies and other autoimmunity processes, whereas the secondary form arises with coexisting autoimmune disease and is not always antibody-mediated.

Common Symptoms

Dizziness, pale skin, shortness of breath, and fatigue.

Coexisting Diseases and Conditions

Rheumatoid arthritis, hepatitis, inflammatory bowel disease, myasthenia gravis, SLE, autoimmune hemolytic anemia, acquired hypogammaglobulinemia, autoimmune polyglandular syndrome, and thymoma.

Risk Factors

Pre-existing autoimmune diseases, tumors in the thymus, and viral infections (including parvovirus B19).
