Isoantibodies to human serum proteins in children after blood and plasma transfusions.
The influence of blood and blood-product therapy was studied in two groups of children: 1) 90 children who had exchange transfusion after birth because of serologic incompatibility (aged 5 months to 5 years). In 7 children of this group isoprecipitins were detected. In 4 cases they reacted probably with lipoprotein group factors. One child had anti-Gm 2 antibodies. 2) 32 patients with various blood diseases, aged 18 months to 17 years, who had multiple transfusions of blood or plasma. In 12 children of this group (38%), precipitins were demonstrated. Two had antibodies to lipoprotein group factors. No anti-Gm antibodies were discovered in this group of children. The results of the study indicate an influence of transfusions of blood and blood products on the formation of antibodies to human proteins.
