  • Title: [Pseudomonas aeruginosa immunoglobulin in experimental pneumonia].
    Author: Pennington JE, Pier GB.
    Journal: Infection; 1987; 15(1):56-9. PubMed ID: 3106230.
    Abstract:
    A guinea pig model of experimental Pseudomonas aeruginosa pneumonia was used to evaluate factors affecting the efficacy of passive immune therapy with Psomaglobin N, a hyperimmune P. aeruginosa globulin. Animals treated 2 h after infection with a single intravenous infusion of Psomaglobin N, 500 mg/kg, demonstrated 33% survival. Lower dosages were less effective and no survivors occurred among albumin-treated controls. Treatment with Psomaglobin N was effective if given 2 h or 8 h after infection but not if delayed until 24 h after infection. Animals rendered neutropenic with cyclophosphamide did not survive if treated with Psomaglobin N alone. However, when Psomaglobin N was added to tobramycin treatment, a significant increase in survival occurred (86%) as compared to that observed with tobramycin alone (43%) (p less than 0.05). We conclude that Psomaglobin N may offer a useful therapeutic option in management of P. aeruginosa pneumonia.
