ABO Haemolytic Anaemia in Transplanted Patients

Abstract
A case of severe intravascular haemolysis, due to an ''auto-anti-B antibody'', and a case of transient haemolytic anaemia, due to an ''auto-anti-A antibody'', following allogeneic organ transplantation, are reported. Both patients were receiving immunosuppressive therapy with cyclosporin A and were non-secretors of A, B and H substances.
