[Acquired autoimmune hemolytic anemia after liver transplantation by "auto"-anti-A and "auto"-anti-P1]

Abstract

A 47-year-old man (group A) received a cadaver liver from a group 0 donor. On day 8 after the transplant the recipient developed severe immune hemolysis and showed a positive direct antiglobulin test due to two antibodies (anti-A and anti-P1) of transplant donor origin. The possible mechanisms involved in "autoantibody" formation in the recipient are discussed.
