Abstract
The presence of both complete IgM autoagglutinins and IgG autoantibodies in warm autoimmune hemolytic anemia (AIHA) is an uncommon finding. Over a 6-year period, only 5 of 115 (4.1%) patients with AIHA had IgM and IgG autoantibodies. In 3 of the 5 cases, the complete IgM autoagglutinins reacted up to 30 °C and these patients responded well to corticosteroid or other therapies for warm AIHA. The 2 patients who had warm (37 °C) reactive IgM autoagglutinins, were refractory to corticosteroids, splenectomy and cytotoxic drugs, and died due to the complications of hemolytic anemia. The data in these 5 cases suggest that the thermal amplitude of the IgM antibody in these unusual AIHA cases may be predictive of refractoriness to therapy and poor clinical outcome.
