Mixed Autoimmune Hemolytic Anemia - A Rare Case Report

Abstract

Abstract Mixed autoimmune hemolytic anemia (MAIHA) is a rare clinical condition where both warm and cold antibodies cause red cell destruction, leading to anemia. MAIHA can present as a blood group discrepancy or crossmatch incompatibility, which can be very challenging for transfusion medicine services to diagnose and issuing of best-matched blood. Therefore, a comprehensive immunohematology workup, including a monospecific direct antiglobulin test, and indirect antiglobulin test is performed to determine the thermal amplitude and titer of autoantibodies. It is important to be aware of this phenomenon because, like warm AIHA and MAIHA should be treated immediately, with steroids. We hereby report a case of a 14-year-old girl presenting with a history of generalized weakness and dizziness; preliminary investigations revealed anemia, increased reticulocyte count, and antinuclear antibodies positive. Hence, further diagnosis of MAIHA associated with systemic lupus erythematosus was made. A high-dose steroid therapy was given to the patient, and significant improvement was seen clinically.
