Allorgafting for Aplastic Anemia on a Background of HELLP Syndrome in Identical Twins.

Syngeneic twins presented at different times with HELLP (Hemolysis, Elevated Liver Enzymes, Low Platelets) Syndrome, and in both cases, a post-pregnancy with severe aplastic anemia (SAA). Both were managed with matched related donor bone marrow transplant, again at different times, from a HLA-matched third sister, and are doing well more than 15 years later. Management of AA is discussed.
