The pharmaceutical composition and a method of treatment of infectious diseases, such as otitis media, paranasal sinusitis, labyrinthitis and meningitis are described. The composition comprises EP2E or homologues thereof.

Use of antimicrobial proteins and peptides for the treatment of otitis media and paranasal sinusitis

Disclosed herein is a composition and a method for the treatment of otitis media and paranasal sinusitis using human defensins, lysozyme and/or lactoferrin as a new class of non-antibiotic antimicrobials. From studies of otitis media and paranasal sinusitis, it was observed that certain innate immune modulators were important in the bodies response to the infection. Therefore, these innate immune modulators, lysozyme, lactoferrin, and defensins were tested for use as a non-antibiotic treatment for infection, particularly infections such as otitis media and sinusitis.
