Erythrocytapheresis: Do Not Forget a Useful Therapy!

Area of Science:

• Hematology
• Therapeutic Apheresis

Background:

• Pathologically altered erythrocytes necessitate advanced treatments.
• Increasing global migration introduces more patients with severe malaria and sickle cell anemia.
• Red blood cell exchange (erythrocytapheresis) is a therapeutic apheresis technique.

Purpose of the Study:

• To evaluate the efficacy and safety of erythrocytapheresis in managing sickle cell anemia and sickle cell thalassemia.
• To explore erythrocytapheresis as an alternative to blood transfusions, particularly for preventing iron overload.
• To assess its role in preventing complications associated with these hematological disorders.

Main Methods:

• Erythrocytapheresis was employed for long-term prophylaxis in sickle cell anemia and sickle cell thalassemia patients.
• Treatment aimed to achieve specific end hematocrit levels.
• Liver susceptometry was used to document iron balance.

Main Results:

• Erythrocytapheresis demonstrated efficiency in treating severe malaria by reducing parasite load and restoring oxygen transport.
• It effectively breaks the cycle of sickling and hypoxia in sickle cell disease complications like stroke and acute chest syndrome.
• Prophylactic erythrocytapheresis prevented hemolysis in ABO-incompatible stem cell transplantations.
• Improved iron balance was observed in treated patients.

Conclusions:

• Erythrocytapheresis is a safe and highly efficient therapeutic option for various hematological conditions, including sickle cell disease and severe malaria.
• It offers a valuable alternative to traditional transfusions, mitigating long-term risks like iron overload.
• This apheresis method provides reproducible control over hematological parameters and reduces disease-specific complications.
