title: Autoimmune hemolytic anemia due to anti B autoantibody.
abstract: An anti B autoantibody was found during a routine cross-matching of the blood of two patients who presented with fever and hemolytic anemia. It appeared transiently and was shown to be IgM- and cold-reacting. The patients had an excellent response to a short course of corticosteroid treatment.
