Compatibility problems after intravenous immunoglobulin--a case report.

ABSTRACT

Serious incompatibility was noted in a patient diagnosed as acute Guillain Barre syndrome treated with intravenous immunoglobulin. Patient had positive direct and indirect antiglobulin test and the auto control was negative. There was no clinical signs of hemolysis. Patient's blood group was O D positive and cross matched several units of ABO compatible D positive and D negative blood. Only one unit was compatible. These findings suggest that the particular intravenous immunoglobulin contained a mixture of saline and immune antibodies having different specificity. As the number of patients getting treated with intravenous immunoglobulin is on the rise more and more compatibility problems should be anticipated and should be borne in mind during serological testing and evaluation.
