Pure red cell aplasia is a rare form of anemia caused when the bone marrow stops producing red blood cells, but produces white blood cells normally. It is usually a symptom of another underlying disorder, but can be congenital or ideopathic.
Several other conditions can cause red cell aplasia, including:
- Autoimmune conditions
- A Thymoma
- Infections, including HIV, Herpes and Hepatitis
- Drugs, such as erythropoietin
In addition to an infusion of red blood cells, the condition usually responds well to ciclosporin.
