The clinical significance of the Gerbich antibodies has been described as variable and there are no well-documented reports of hemolytic transfusion reactions (HTRs).


We present the case of a woman with a long history of documented anti-Ge3 alloantibody who received multiple units of Ge+ red blood cells (RBCs) uneventfully. During the first admission to our hospital she was transfused 8 units of Ge+ RBCs and had a negative monocyte monolayer assay (MMA) before receiving the units. Within 2 weeks of the transfusions, the anti-Ge3 became significantly stronger by indirect antiglobulin test, and the MMA increased from 2.2 to 79.5% reactivity. She returned 4.5 years later with an emergent need for blood and was transfused with 2 units of Ge+ RBCs after premedication with steroids and intravenous immunoglobulin.


The first unit was transfused without incident; however, she developed clinical and laboratory signs consistent with an acute HTR with the second unit.


After a comprehensive review of the literature, we believe this to be the first well-documented case of acute HTR due to anti-Gerbich alloantibodies.
