York City.
1. Two cases of infectious mononucleosis complicated by acute hemolytic
anemia are presented. One of these patients had, in addition, an underlying
Mediterranean anemia.
2. Hemolytic anemia is a rare complication of infectious mononucleosis.
3. Thirteen similar cases have been collected from the literature, and the
cumulative data summarized.
4. Recovery occurred in all cases. Splenectomy was considered necessary in
only two.
5. The etiology of hemolytic anemia in infectious mononucleosis is obscure
but there is good evidence to indicate it may be different in different cases.
Hypersplenism initiated by infectious mononucleosis could best explain the
authors cases whereas the elaboration of hemolytic antibodies would best
explain some of the reported cases.
