Abstract:
Pure red cell aplasia (PRCA) is a rare condition leading to erythroid bone marrow failure. Parvovirus is one of the rare causes of PRCA in older adults. We present a 73-year-old man on high dose prednisone who presented with rapid functional decline and shortness of breath and was found to have normocytic normochromic anemia with low reticulocyte counts. On further workup, he was found to have elevated immunoglobulin M (IgM) titer of parvovirus B-19 antibody. The patient was managed with supportive care with blood transfusion, hydration and had improvement in his symptoms.
Insights
Pure red cell aplasia (PRCA) is a rare bone marrow failure. Parvovirus B-19 infection can cause PRCA in older adults, as seen in this case managed with supportive care.
Area of Science:
- Hematology
- Virology
- Immunology
Background:
- Pure red cell aplasia (PRCA) is a rare hematologic disorder characterized by erythroid-specific bone marrow failure.
- While various causes exist, parvovirus B-19 infection is an uncommon but significant etiology, particularly in elderly populations.
Observation:
- A 73-year-old male on high-dose prednisone presented with acute functional decline and dyspnea.
- Clinical evaluation revealed normocytic, normochromic anemia with suppressed reticulocyte counts, indicative of bone marrow dysfunction.
Findings:
- Further investigation identified an elevated immunoglobulin M (IgM) titer for parvovirus B-19 antibody.
- This confirmed parvovirus B-19 infection as the likely cause of PRCA in this patient.
Implications:
- This case highlights parvovirus B-19 as a potential cause of PRCA in immunocompromised or elderly individuals.
- Supportive management, including blood transfusions and hydration, led to symptomatic improvement, underscoring the importance of prompt diagnosis and care.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
