Lack of transmission of neutrophil and platelet antibodies by intravenous immunoglobulin in bone marrow transplant patients.
BACKGROUND
Several studies have demonstrated that the administration of intravenous immunoglobulin (IVIG) may be followed by the transient appearance of positive red cell antibody screens, positive direct antiglobulin tests, and, occasionally, frank hemolysis. However, little information is available regarding the possibility that IVIG could transmit neutrophil and/or platelet antibodies.


METHODS
Serum samples were obtained both immediately before and immediately after the administration of 12 separate lots of commercially available IVIG to bone marrow transplant patients.


RESULTS
None of the patients were shown by standard granulocyte immunofluorescence testing to have acquired neutrophil antibodies. Four of the 12 postinfusion sera were positive for platelet antibodies in standard platelet suspension immunofluorescence testing, but in all four instances the corresponding preinfusion serum was positive as well.


CONCLUSIONS
The risk of acquiring neutrophil and/or platelet antibodies after the administration of commercially available IVIG appears to be low.
