ANTIBODIES TO GAMMA-GLOBULIN IN INFANTS AND CHILDREN EXPOSED TO ISOLOGOUS GAMMA-GLOBULIN

Abstract
Isoantibodies directed against human gamma-globulin were found in children receiving single and repeated injections of gamma-globulin and in those who had received blood transfusions at birth. Nine of 14 children receiving repeated gamma-globulin injections had anti-gamma-globulin antibodies. One-third of all children exposed to gamma-globulin by transfusion or injection, but only 6% of unexposed children had anti-gamma-globulin antibodies. Females appear to have a higher incidence of sensitization than males. The possibility exists that these antibodies may be implicated in reported anaphylactic reactions to gamma-globulin.
