Abstract
Autoimmune hemolytic anemia (AIHA) has been considered to be unresponsive to intravenous gammaglobulin (IVGG) at the doses that are effective in immune thrombocytopenic purpura and autoimmune neutropenia (usually 2 g/kg total dose). This study reports the use of a higher dose (5 g/kg total dose over 5 days) in four severe cases of AIHA which resulted in a sustained remission in two patients, a transient response in the third, and a failure in the fourth patient. These data suggest that larger quantities of IVGG may be needed in this disease, possibly because the reticuloendothelial system appears to be enlarged in AIHA patients.
