Immunomodulation of E.Coli Nissle 1917 in Patients With Grass Pollen Rhinoconjunctivitis (Ecorhino)

November 12, 2009 updated by: Charite University, Berlin, Germany

Explorative Analysis of the Immunomodulatory Capacities of Apathogenic Escherichia Coli Nissle 1917 in Patients With Rhinoconjunctivitis Due to Grass Pollen Allergy

Due to the worldwide increasing prevalence of the allergic rhinoconjunctivitis, new therapeutical strategies are needed. The symptomatic treatment with topical and systemic antihistamines and corticosteroids are often insufficient. E.coli Nissle 1917 has immunomodulatory capacities and reveals less side effects. E.coli Nissle 1917 has no sedative properties and exhibits no hepatotoxic qualities. Thus, E.coli Nissle 1917 represents a new relevant therapeutical agent.
