Titration of Igs contained in an intravenous IgM-enriched preparation against selected pathogens involved in sepsis.

Abstract:

:The goal of our work was to titer the IgG, IgM and IgA in Pentaglobin® (a preparation enriched in IgM), targeting specific surface antigens of Gram-positive and Gram-negative bacteria as well as a C. albicans strain. Lipopolysaccharides from Gram-negative bacteria, peptidoglycan and lipoteichoic acid from the other microorganisms were extracted and used in several ELISA assays in order to determine the titration of immunoglobulins in Pentaglobin® directed towards the aforementioned surface antigens. Our results showed an overall immunoglobulin titer of at least 103 in Pentaglobin® with some exceptions for the IgA titers and for some immunoglobulin titers against E. faecalis, K. pneumoniae and P. aeruginosa. According to these results, Pentaglobin® can be considered as a potential adjuvant for antimicrobial therapy.
