title: Intravenous gamma globulin in the management of patients with hypogammaglobulinemia.
abstract: The safety and efficacy of plasmin-treated gamma globulin (PG-GG), an intravenous preparation with low anticomplementary activity, was assessed as an antibody replacement therapy in 14 patients with hypogammaglobulinemia. Seven were studied in 2 treatment periods of 6 and 15 mo on PT-GG with an intervening control period of intramuscular gamma globulin (IM-ISG). Frequency of infusions ranged from 2 to 4 wk to maintain a serum IgG concentration of less than 2.5 mg/ml. Three patients with severe chronic pulmonary disease were removed from the study because of lack of clinical improvement and were placed on single-donor plasma. The remaining 11 patients had a decrease in the number of hospitalizations or severe infections. Five patients had one or more systemic reactions (21/240 infusions). Symptoms abated rapidly with temporary interruption of the infusion. From these results, we conclude that PT-GG represents a relatively safe, efficacious mode of replacement therapy which has had uniformly high acceptance in patients with hypogammaglobulinemia.
