Explorative analysis of the immunmodulatory capacities of apathogenic Escherichia coli Nissle 1917 in patients with rhinoconjunctivitis due to grass pollen allergy.

Phase 1
Conditions
Due to the worldwide increasing prevalence of allergic rhinoconjunctivitis (AR), new therapeutical strategies are needed. The symptomatic treatment with topical and systemic antihistamines and corticosteroids are often insufficient. E. coli Nissle 1917 (EcN) has immunmodulatory capacities and reveals less side effects. EcN has no sedative properties and exhibits no hepatotoxic and nephrotoxic qualities. Thus, EcN represents a new relevant therapeutical agent.
