Method and compositions for the direct concentrated delivery of passive immunity
First Claim
1. A method for preventing infections in human and animal hosts that are derived from wounds, burns, or biomaterials, comprising the steps of:
- preparing a surgical or trauma site of a wound, burn or biomaterial implant site in a human or animal host where damaged tissue exists, wherein said preparing is selected from the group consisting of cleaning, decontaminating, debriding and surgery;
directly applying an amount of an immunoglobulin composition containing a combination of IgG, IgM and IgA, wherein said composition contains elevated levels of IgM between 200-300 mg/dl and IgA between 400-500 mg/dl when compared with normal serum levels, directly on either tissue surfaces at said surgical or trauma site or on a biomaterial to be applied at said biomaterial implant site to produce an immunocompetent inflammatory zone sufficient to prevent adhesion of microorganisms to said tissue surfaces, said biomaterial implant site or a biofilm formation and to pre-opsonize said microorganisms for rapid intracellular killing by host defense mechanisms, said step of directly applying said composition occurring prior to microbial attachment to said tissue surfaces, biomaterial implant site or biofilm formation, said step of directly applying being performed by a process selected from the group consisting of applying said immunoglobulin composition to said tissue surfaces or said biomaterial implant site at a time of surgery or trauma or within a period of six hours after said surgery or trauma, or using a biomaterial pre-coated with said immunoglobulin composition; and
preventing or reducing infections in said human or animal host at said surgical or trauma site with said immunoglobulin composition or biomaterial pre-coated with said immunoglobulin composition.

Abstract
Compositions containing a high concentration of the full repertoire of immunoglobulins, including IgA, IgM and IgG, are used to combat infections from microorganisms and viruses at a wound, surgical, or burn site, or normal tissue times of risk of infection. The compositions can contain elevated antibody titers for several specific pathogens including S. aureus, Coagulase Negative Staphylococci Enterococci, S. epidermidis, P. aeruginosa, E. coli, and Enterobacter spp., etc. The compositions are applied directly to a wound or burn site as an ointment, creme, fluid, spray, or the like, prior to viral or bacterial attachment or biofilm formation such that adhesion of the pathogens is inhibited and the pathogens closest to the wound or burn site will be pre-opsonized for phagocytic killing prior to toxin release. The immunoglobulins in the composition can be immobilized on a biocompatible material such as collagen, fibrin, hyaluronan, biodegradable polymers, and fragments thereof, which will be placed in-situ at the wound, surgical or burn site. In addition, the immunoglobulins in the composition may be coated on the body contacting surface of an implantable device such as a catheter, contact lens or total joint. The inventive compositions have particular application in preventing infections.
