How does anti-D immunoglobulin work to treat ITP?
A. Anti-D immunoglobulin (or anti-D) is used in patients who cannot tolerate or do not respond to initial treatment with corticosteroids or IVIG. Patients receiving anti-D must have Rh-positive blood and must not have had a splenectomy. It is believed that anti-D forms red blood cell (RBC) complexes that block the destruction of the targeted platelets.
