[Autoimmune hemolytic anemia with cold antibodies and hemoglobinuria secondary to EBV infection].

The infection caused by EBV can be followed by immunological complications. One of these is autoimmune hemolytic anemia that up to today has been observed during infective mononucleosis only a few times. The authors describe a patient with this rare complication of the EBV infection and discuss its main clinical, pathogenetic and laboratory aspects, with particular attention to the presence of hemoglobinuria and to the absence of anti-i-antibodies. The disease's evolution was spontaneously favorable. For this reason and for the possible risks secondary to transfusions and to other therapeutical interventions, the authors believe that in autoimmune hemolytic anemia a vigil wait is more opportune before beginning the therapy.
