DECREASED INCIDENCE OF ADVERSE INFUSION REACTIONS IN HYPOGAMMAGLOBULINEMIC CHILDREN RECEIVING LOW pH INTRAVENOUS IMMUNOGLOBULIN

Abstract
Eighteen patients (ages eight months to 20 years) with disorders of immunoglobulin and antibody production received infusions of two preparations of intravenous immunoglobulin in a blind crossover trail. The incidence and severity of immediate adverse infusion reactions was significantly lower with low pH immunoglobulin; ten patients (56%) experiencing immediate reactions with the standard preparation and only one patient experiencing an immediate reaction with the low pH preparation (p < 0.01). Infusion times were significantly less with the low pH preparation (p < 0.02) and patient tolerance, determined by visual analogue scores, was significantly better than with the standard preparation (p < 0.01). HOwever, the incidence of delayed reactions (44%) was the same for both infusions.
