Anaphylactic Reactions after Gamma Globulin Administration in Patients with Hypogammaglobulinemia

Abstract
VYAS and co-workers1 were the first to identify anti-IgA antibodies as the cause of anaphylactic reactions to human blood products in patients with selective IgA deficiency. Other reports of anaphylaxis due to anti-IgA antibodies soon followed,2 3 4 5 6 7 8 9 10 11 12 13 including several reports of anaphylactic reactions in patients with common variable immunodeficiency.3 4 5 6 7 8 , 11 Although such patients have severe defects in antibody production, they often retain the ability to produce autoantibodies. Gamma globulin replacement is essential in the management of hypogammaglobulinemia,6 in contrast to selective IgA deficiency. Therefore, it is important to find ways to circumvent these life-threatening anaphylactic reactions and to provide adequate replacement therapy. . . .
