Successful treatment of refractory autoimmune haemolytic anaemia in a post-unrelated bone marrow transplant paediatric patient with rituximab.

Here, we report a case of paediatric beta-thalassaemia major patient who underwent unrelated T cell-non- depleted bone marrow transplantation and developed a complication of autoimmune haemolytic anaemia (AIHA) refractory to corticosteroid and intravenous immunoglobulin therapy. After this child received two doses (375 mg/m2/dose) of rituximab (anti-CD20 monoclonal antibody), his AIHA was resolved.
